The impact of zoonotic diseases transmitted by pets on human health and the economy

In the context of all causes of human morbidity and mortality, or even within the context of all infectious diseases affecting the public health, pet-associated zoonotic infections are of moderate importance. The data documented in Table 1, however, indicate that they do exact significant human health and economic costs. If complete data were available for all of the infections shown in Table 1, the costs would be considerably higher. Moreover, most of these diseases are preventable through educating the public, particularly pet owners, of the zoonotic potential of these diseases, so that they may take precautions to minimize the risks leading to infection. These measures include appropriate health care of pets to eliminate infectious agents, reducing the number of uncontrolled, ownerless pets as well as unwanted or poorly supervised pets, preventing pets from soiling public places with their feces, excluding animals from areas where children play, enforcing leash laws, and promoting responsible pet ownership. Veterinarians, physicians, and public health agencies can aid in these efforts; ultimately, however, the responsibility lies with the pet owner.     

All creatures great and minute: a public policy primer for companion animal zoonoses

Approximately 63% of US households have at least one pet, a large percentage of which are considered family members. Pet owners can derive substantial physical and psychological benefits from interaction with companion animals. However, pet ownership is not without risks; zoonotic diseases are increasingly drawing the attention of healthcare professionals, policy makers and the general public. While zoonoses of 'traditional' pets are widely recognized and their prevention and treatment factors are generally known, the growing popularity of 'non-traditional' pets has the potential to facilitate human exposure to novel zoonoses. However, the greatest risk of zoonoses probably arises from animals taken directly from the wild to serve as pets. Non-governmental organizations, state veterinary associations and others have been calling for increased regulation of animal imports, some proposing that all 'exotics' be banned from the pet trade. Because zoonotic diseases of companion animals are influenced by interacting factors of ecological, technical, socio-economic, and political origin, efforts to minimize their impact need be multi-dimensional, simultaneously addressing both the ecological and socio-political drivers of disease emergence and transmission. This study is intended to serve as a primer for animal care professionals seeking to engage with policy makers and the pet industry on the prevention of companion animal zoonoses. We provide background on the human-animal bond, risks of zoonoses associated with groups of companion animals, and the public policy context, as well as identify the factors needed to build a comprehensive approach to companion animal zoonoses risk management. Also included are examples of innovative, non-regulatory initiatives designed to limit the spread and impact of companion animal zoonoses, including a reptile salmonella poster, the National Reptile Improvement Plan, Habitattitude campaign, Pet Zoonoses Committee, and a wildlife disease surveillance initiative known as Project TripWire.     

Keeping of pets--assessment of accessories

In keeping of pets accessories play an important role. They serve to improve the conditions of pet keeping or even help to make it possible at all. Beyond that, accessories enrich activity of the animals and thus may increase their well-being. But accessories can endanger health and life of the pets due to deficient quality or due to inadequate use. This paper demonstrates the sources of danger potentially arising from accessories by pointing out examples. On the other hand exemplary paraphernalia and ways of pet keeping are presented which are qualified to increase well-being of the pets and to avoid physical impairment.     

Retention of provided identification for dogs and cats seen in veterinary clinics and adopted from shelters in Oklahoma City, OK, USA

Personalized identification (ID) tags that contain contact information for the dog or cat owner can help assure lost animals are quickly reunited with their owners. The authors have previously reported that while the majority of pet owners stated that ID tags were very important, only a third responded that their pet wears an ID tag. The objective of this study was to evaluate if providing and putting on the pet a free collar and ID tag during an owner's visit to a veterinary hospital or spay/neuter facility increased the likelihood that the pet owners would actually keep the identification on their pet at least 6-8 weeks after they were placed on the pet. A second population of dogs and cats that were adopted from animal control and humane society shelters were also studied to assess retention of a collar and personalized ID tag. Telephone follow-up occurred a mean of 8 weeks after the tag was applied. Retaining and using the tag significantly increased for the veterinary group with 13.8% reporting their pets were currently wearing an ID tag pre-intervention, and 84.3% reporting their pets were currently wearing and ID tag post-intervention. Of the dogs and cats that were adopted, at follow-up 94% of owners reported their pets were currently wearing an ID tag. Approximately 5% of those who participated in the post-intervention survey lost a pet and recovered that pet because of the ID tag. This suggests that ID tagging is an effective method to potentially decrease stray intake into shelters and return pets home. The data also support placing tags and collars directly on pets as a method to retain those ID tags and collars on the animals, thus increasing the likelihood they will be returned home if lost or during a disaster.     

Future directions in training of veterinarians for small exotic mammal medicine: expectations, potential, opportunities, and mandates

Small exotic mammals have been companions to people for almost as long as dogs and cats have been. The challenge for veterinary medicine today is to decipher the tea leaves and determine whether small mammals are fad or transient pets or whether they will still be popular in 20 years. This article focuses on pet small-mammal medicine, as the concerns of the laboratory animal are better known and may differ profoundly from those of a pet. Dozens of species of small exotic mammals are kept as pets. These pet small-mammal species have historically served human purposes other than companionship: for hunting, for their pelts, or for meat. Now, they are common pets. At present, most veterinary schools lack courses in the medical care of these animals. Veterinary students need at least one required class to introduce them to these pets. Currently, there are no small-mammal-only residency programs. This does not correspond with current needs. The only way to judge current needs is by assessing what employers are looking for. In a recent JAVMA classified section, almost 30% of small-animal practices in suburban/urban areas were hiring veterinarians with knowledge of exotic pets. All veterinarians must recognize that pet exotic small mammals have changed the landscape of small-animal medicine. It is a reality that, today, many small-animal practices see pet exotic small mammals on a daily basis.     

Healthy pets, healthy people.

Zoonoses, diseases that can be transmitted from animals to humans, can pose serious health risks to immunocompromised people. Although pets can carry zoonoses, owning and caring for animals can benefit human health. Information exists about preventing transmission of zoonoses, but not all physicians and veterinarians provide adequate and accurate information to immunocompromised pet owners. This disease prevention/health promotion project provides physicians and veterinarians with information, created specifically to share with patients and clients, about the health risks and benefits of pet ownership. Further, "Healthy Pets, Healthy People" encourages communication between veterinarians, physicians, clients, and patients and can serve as a model program for a nation-wide effort to aid health professionals in making recommendations about pet ownership for immunocompromised people.     

Zoonoses transmitted by mouse and rat maintained as laboratory or pet animals

Large numbers of mice (Mus spp.) and rats (Rattus spp.) are maintained for scientific reasons and as pet animals in Germany. While laboratory animals are monitored for pathogenic agents, the hygienic status of pet animals is usually completely unknown. Despite great efforts, zoonotic infections were reported even in laboratory settings, e.g. with Hantavirus (Seoul virus), Streptobacillus moniliformis, and Trichphyton mentagrophytes. However, in current reports, zoonotic infections were transmitted by mice and rats maintained as pet animals. This includes infections by Lymphocytic choriomeningitis virus, Leptospira interrogans, Streptobacillus moniliformis, Salmonella enterica, Trichophyton mentagrophytes, and Ornithonyssus bacoti. Furthermore, entero-hepatic Helicobacter spp. of rats and mice are currently discussed to be involved in the etiology of hepatobiliary diseases. Pasteurella spp. of mice and rats do not present a risk for human disease comparable to those species that are transmitted by dogs or cats and might induce serious disease after bites. Altogether, this article lists potential zoonotic agents that were detected in mice and rats and are present in Germany, as well as agents that were reportedly transmitted by mice and rats maintained as laboratory or pet rodents.     

Endocrine diseases of rodents.

The frequency of documented endocrine diseases in rodents and other small mammals varies considerably among the species maintained as pets, biomedical research animals, or display animals in zoos. The clinical diagnosis of endocrine diseases almost never occurs in free-ranging animals in their native habitat. Feral animals that have clinical endocrine disease, such as neoplasia, adrenal cortical hyperplasia, or diabetes, would exhibit clinical signs of altered behavior that would result in their removal by predators. The diagnosis of endocrine disease thus takes place in the relatively protective environment of captivity. This observation should forewarn pet owners and clinicians caring for these animals that the environment contributes to the development of endocrine diseases in these animals.     

Epidemiologic features of pet evacuation failure in a rapid-onset disaster.

OBJECTIVE: To describe epidemiologic features of pet evacuation failure after a hazardous chemical spill in which residents had no warning and only a few hours notice to evacuate. DESIGN: Cross-sectional study. SAMPLE POPULATION: Pet-owning households that evacuated from a hazardous chemical spill with (n = 119) or without (122) their pets. Procedures-Evacuees were surveyed by mail. RESULTS: 261 of 433 (60.3%) dogs and cats in 241 households were not evacuated. Of the 241 households, 119 (49.4%) evacuated with their pets, 98 (40.7%) evacuated without them but later attempted to rescue them, and 24 (10.0%) neither evacuated their pets nor attempted to rescue them. Pet evacuation failure was most common in households that thought the evacuated area was safe for pets. Risk of pet evacuation failure increased in households with many animals, low pet attachment and commitment scores, and low levels of preparedness. Cat evacuation failure was associated with not having cat carriers. Nearly 80% of households that evacuated with their pets found accommodation with friends and family. CONCLUSIONS AND CLINICAL RELEVANCE: Pet evacuation failure was common and jeopardized pets' health and well-being. Logistical challenges to transporting pets were substantial contributors to pet evacuation failure, whereas not knowing where to house a pet was only a minor concern. Most pet owners seemed self-reliant and acted appropriately towards their pets. Such self-reliant behavior by pet owners should be encouraged prior to disasters as part of an evacuation plan for households.     

Animal abuse and intimate partner violence: researching the link and its significance in Ireland - a veterinary perspective

Research on domestic violence has established a substantial association between intimate partner abuse and the abuse of children within the home. It is only recently however, that researchers have demonstrated the correlation between non-accidental injury in animals, and abuse of women by their intimate male partners. A growing body of evidence suggests that animal abuse can be an early indicator for other forms of violent behaviour. This research includes the responses of a sample of 23 women using refuge services in the Republic of Ireland. It investigates the connection between domestic violence and animal abuse, and ascertains if there is sufficient support service for animals and people relevant to domestic abuse. In the survey population, 57% of women reported witnessing one or more forms of abuse, or threats of abuse, of their pets. Five of which were reported to have resulted in the death of the pet. Eighty seven per cent of women felt a facility to accommodate pets would have made their decision to leave the family home easier. Four women disclosed that lack of such a service and concern for the welfare of their companion animals caused them to remain in their abusive relationships for longer than they felt appropriate. Nine families placed pets in the care of family or friends, one woman is unaware of the fate of her pet, while the pets of six families remained with the abusive male after his partner entered a refuge. The majority of women felt unable to talk to anyone about their fears for their pets' welfare. Many felt that there is no service which can provide temporary accommodation for womens' pets while they are in refuge. The results obtained support those found elsewhere in larger studies in the USA and UK, and demonstrate an association of animal abuse in households where there is reported domestic violence.     

Canine and feline nasal neoplasia

Dogs and cats of our society have outgrown their status as merely pets and are now considered our close companions and even family members. This shift in their roles has led to pet owners seeking improved preventative medicine for their four-legged friends. Subsequently, dogs and cats are living longer lives than ever before and developing more old-age-related diseases. One of the most devastating diseases of older animals is cancer. Once a veterinarian has detected cancer in a pet, pet owners seek advice on their next course of action. This article is intended to provide concise information regarding the diagnosis and treatment of intranasal tumors of the dog and cat. This article outlines the forms of nasal tumors that are the most common, the recommended imaging and biopsy techniques to diagnose the tumor, and the most appropriate treatments of them.     

Disease prevalence among dogs and cats in the United States and Australia and proportions of dogs and cats that receive therapeutic diets or dietary supplements

OBJECTIVE: To estimate disease prevalence among dogs and cats in the United States and Australia and proportions of dogs and cats that receive therapeutic diets or dietary supplements. DESIGN: Telephone survey. Sample Population-Dog and cat owners located in 5 geographic areas. PROCEDURES: A telephone survey was administered to dog and cat owners. RESULTS: Of 18,194 telephone calls that were made, 1,104 (6%) were to individuals who owned at least 1 dog or cat and agreed to participate. Information was collected for 635 dogs and 469 cats. Only 14 (1%) respondents indicated that their pet was unhealthy, but 176 (16%) indicated that their pets had 1 or more diseases. The most common diseases were musculo-skeletal, dental, and gastrointestinal tract or hepatic disease. Many owners (n = 356) reported their pets were overweight or obese, but only 3 reported obesity as a health problem in their pets. Owners of 28 (2.5%) animals reported that they were feeding a therapeutic diet, with the most common being diets for animals with renal disease (n = 5), reduced-calorie diets (5), and reduced-fat diets (4). Owners of 107 of 1,076 (9.9%) animals reported administering dietary supplements to their pets. Multivitamins (n = 53 animals), chondroprotective agents (22), and fatty acids (13) were the most common dietary supplements used. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that most dogs and cats reported by their owners to have a health problem were not being fed a therapeutic diet. In addition, the rate of dietary supplement use was lower than that reported for people.     

The prevalence of carriage of meticillin‐resistant staphylococci by veterinary dermatology practice staff and their respective pets

It has been shown that people and pets can harbour identical strains of meticillin‐resistant (MR) staphylococci when they share an environment. Veterinary dermatology practitioners are a professional group with a high incidence of exposure to animals infected by Staphylococcus spp. The objective of this study was to assess the prevalence of carriage of MR Staphylococcus aureus (MRSA), MR S. pseudintermedius (MRSP) and MR S. schleiferi (MRSS) by veterinary dermatology practice staff and their personal pets. A swab technique and selective media were used to screen 171 veterinary dermatology practice staff and their respective pets (258 dogs and 160 cats). Samples were shipped by over‐night carrier. Human subjects completed a 22‐question survey of demographic and epidemiologic data relevant to staphylococcal transmission. The 171 human‐source samples yielded six MRSA (3.5%), nine MRSP (5.3%) and four MRSS (2.3%) isolates, while 418 animal‐source samples yielded eight MRSA (1.9%) 21 MRSP (5%), and two MRSS (0.5%) isolates. Concordant strains (genetically identical by pulsed‐field gel electrophoresis) were isolated from human subjects and their respective pets in four of 171 (2.9%) households: MRSA from one person/two pets and MRSP from three people/three pets. In seven additional households (4.1%), concordant strains were isolated from only the pets: MRSA in two households and MRSP in five households. There were no demographic or epidemiologic factors statistically associated with either human or animal carriage of MR staphylococci, or with concordant carriage by person–pet or pet–pet pairs. Lack of statistical associations may reflect an underpowered study.     

Potbellied pig husbandry and nutrition.

Vietnamese potbellied pigs, when appropriately cared for, make excellent pets for some people. However, their proper housing, care, and training is more challenging to the average person than that required for most traditional pets, such as dogs and cats. Failure to feed and house the pet pig appropriately results in the most common health and behavior problems. The obese, intractable pet pig gives little pleasure to a pet owner and appears to lead a very poor-quality life, frequently leading to the pet pig being given away or worse. Preventing health and behavior problems is easy if pet owners are armed with correct information early, either before or immediately after their acquisition of a pet pig. A veterinarian prepared to share this information can save the lives of many pigs as well as keep clients happy and coming back.     

Pet Ownership,Attitude Toward Pets,and Support for Wildlife Management Strategies

Pet ownership affects engagement with animal-related activities and may be related to support of wildlife management. British participants (N = 220) completed an online survey providing information on pet ownership, attitudes toward pets, and support for wildlife management strategies. Within this sample, pet owners and individuals with positive attitudes toward pets were less supportive of strategies that put human needs before the needs of wildlife, more supportive of strategies attempting to avoid species extinctions, and opposed to strategies requiring compromises of individual species. Pet owners’ affectionate attitudes toward animals and opposition to their exploitation may be important in dictating attitudes toward wildlife. Conservation planners could apply these findings when seeking support for management strategies that constrain freedoms of pets and wildlife. Utilizing the sympathetic attitudes of pet owners toward animals by focusing on welfare and survival benefits for wildlife species may help foster support for management strategies.     

Euthanasia & thanatology in small animals

The study of thanatology has recently taken on increased importance in the field of veterinary medicine. Today, the roles of companion animals have expanded to include beloved pet and family member, provider of social and emotion support, and in the case of service dogs, provider of assistance to owners with special needs. For these reasons, companion animals have taken on greater significance within their human families. Their deaths can be as painful and difficult for their families as the death of human family members. Veterinarians are tasked with working in concert with the pet owner, throughout the lifetime of the pet, to promote the pet’s health and well-being. In critical and or terminal situations, it is the veterinarian’s role to educate the owner so that informed decisions regarding treatment options or a decision to euthanize the pet can take place. In veterinary medicine, euthanasia means to end life painlessly. Veterinarians and owners, working in partnership to make subjective and objective assessments on the pets quality of life, produce the best results. For the veterinarian, the medical approach (including: clinical history, physical exam, laboratory tests, diagnosis, prognosis and treatment) can assist in assessing the pet’s physical health status, any potential treatments, and the likely short and long term outcomes. The owner’s role in the partnership is to subjectively assess overall behavioral changes and the pet’s quality of life. Once owners have decided to euthanize their pet, there are still more factors to consider: where to perform the procedure, which family members will be present, and how the remains will be handled. The veterinarian can do everything possible to minimize any anxiety for the pet during the euthanasia, including administration of a tranquilizer prior to the procedure. The veterinarian will allow the pet’s family time to say goodbye and educate them on what to expect when their pet dies. There is a possibility that other pets that lived in the same household may also experience distress at the loss of their animal family member. The veterinarian can let the owners know what signs may be signaling depression or anxiety in that pet. The grieving process is extremely personal and people must be allowed to grieve in the way that helps them deal with their loss. Veterinarians need to be careful not to minimize the owner’s loss or grief. The owner will count on the veterinarian’s guidance and expertise when making decisions affecting their pet’s well-being. Making an informed decision can help assuage any guilt about opting for euthanasia when done in the best interest of the pet.     

Survey of Zoonotic Dermatoses in Client‐Owned Exotic Pet Mammals in Southern Italy

Several ‘exotic’ mammalian species (e.g. rabbits, rodents, ferrets and hedgehogs) live in close proximity to humans as companion pets. Skin diseases (SD) are frequent causes of morbidity in exotic pet mammals, and most of those SDs have a zoonotic potential. The purpose of this study was to determine the frequencies and types of zoonotic dermatosis (ZD) in client‐owned, exotic pet mammals in Southern Italy. Six‐hundred and fifty‐five medical records of exotic pet mammals examined between 2011 and 2012, across twenty private practice veterinary clinics around the Naples area (Italy), were retrospectively evaluated and screened for animals diagnosed with SDs (rabbits n = 455, guinea pigs n = 93, ferrets n = 64, hedgehogs n = 19, chinchillas n = 13 and rats n = 11). The records of animals diagnosed with SD, whose causative agents had a zoonotic potential, were selected for analysis. The Mann–Whitney independent test was used for statistical analysis. A P value ≤0.05 was considered statistically significant. Eighty‐two records (12.5%) of animals with ZD were identified. Of those, 56.1% (46/82) were affected by fungal infections and 42.7% (35/82) by parasitic infections. No zoonotic bacterial or viral infections were diagnosed. Dermatophytosis was significantly diagnosed more frequently in younger animals. The results of this survey indicate that exotic pet mammals may serve as active carriers for many highly contagious pathogens with zoonotic potential. Awareness and vigilance by the veterinary practitioner is crucial in the prevention of occurrences of ZDs. Children frequently come in close contact with exotic pets. To prevent the unplanned transmission of pathogen from pet to human, an active routine screening examination and preventative treatments are strongly recommended for every newly purchased pet mammal.     

Pet ownership increases human risk of encountering ticks

We examined whether pet ownership increased the risk for tick encounters and tickborne disease among residents of three Lyme disease‐endemic states as a nested cohort within a randomized controlled trial. Information about pet ownership, use of tick control for pets, property characteristics, tick encounters and human tickborne disease were captured through surveys, and associations were assessed using univariate and multivariable analyses. Pet‐owning households had 1.83 times the risk (95% CI = 1.53, 2.20) of finding ticks crawling on and 1.49 times the risk (95% CI = 1.20, 1.84) of finding ticks attached to household members compared to households without pets. This large evaluation of pet ownership, human tick encounters and tickborne diseases shows that pet owners, whether of cats or dogs, are at increased risk of encountering ticks and suggests that pet owners are at an increased risk of developing tickborne disease. Pet owners should be made aware of this risk and be reminded to conduct daily tick checks of all household members, including the pets, and to consult their veterinarian regarding effective tick control products.
