Prevalence and antimicrobial resistance of Salmonella spp. in pet mammals, reptiles, fish aquarium water, and birds in Trinidad

The prevalence of Salmonella spp. was determined in 970 animals comprising 423 pet birds, 485 fish aquaria water and 62 other pets (40 pet mammals, 14 reptiles, eight others - crustaceans, snail, stingray) from both pet shops and households throughout Trinidad. The serotypes of Salmonella spp. isolated were identified and the resistance to various antimicrobial agents was determined. Overall nine (0.9%) of 970 pet animals were positive for Salmonella spp. Six isolates of Salmonella spp. were recovered from all pet birds with two isolates of serotype Aberdeen and one isolate each of Thompson, Rubislaw, Panama and Newport. The prevalence of Salmonella spp. in birds was 0.9%. Four isolates of Salmonella spp. were recovered from fish aquaria water, serotypes included Panama (two isolates), Newport (one isolate) and Virchow (one isolate). Prevalence of Salmonella spp. from fish aquaria was 0.4%. No isolate of Salmonella spp. was detected in pet mammals sampled while two isolates were recovered from reptiles, S. Enteritidis and S. Montevideo. One isolate of Salmonella spp. was recovered from a stingray, serotype unknown. Antimicrobial resistance was present is all animal types. The highest prevalence of resistance was to streptomycin among isolates from birds (83.3%) and other pets (100.0%) while isolates from fish aquarium water exhibited comparatively high resistance to cephalothin (50.0%). It was concluded that the isolation of Salmonella spp. from apparently healthy birds, fish aquarium water and other pet animals may pose a health risk to their owners and contacts as all serotypes are known to be potentially pathogenic depending on the oral dosage of the organism and the immune status of those in contact. The high prevalence of resistance to antimicrobial agents among Salmonella isolates across pet species may pose chemotherapeutic consequences to their owners and contacts.

Numbers of dogs, cats, birds, and exotic animals in veterinary practices in the Netherlands 1994-2005 and possible consequences for the veterinary curriculum

The species of pets owned in the Netherlands are constantly changing, and it is important that veterinary practitioners have information about the number and species of pets presented in veterinary practice. Using the same methodology as in 1994, we determined the relative importance of the various pet species in 2005 and compared these data with those for 1994. The most notable findings were a 25% increase in the number of birds and exotic animals seen in small and large animal practices (from about 10% to about 12.5%), a doubling of the number of birds and tripling of the number of pigeons seen in mixed practices, a doubling of the number of reptiles seen in small animal practices, and a 10-fold increase in the number of fish seen in veterinary practices in general. There was a significant decrease in the proportion of cats (from 46% to 40.7%) and an increase in the proportion of dogs (from 44% to 46.7%). These trends in veterinary practice consultations did not parallel those seen in pet ownership. The increase in the number of birds (especially pigeons), reptiles, and fish seen in veterinary practice emphasizes the need to pay attention to these species in the standard companion animal curriculum.     

The Feeding of Live Food to Exotic Pets: Issues of Welfare and Ethics

Live food items are often fed to exotic pet species whether they are birds, amphibians, reptiles, or mammals. This raises issues of welfare, both of the animals fed live prey items and the prey itself. Concerns over live food welfare are particularly marked in the feeding of vertebrate prey items and evidence presented here shows the prolonged time taken for rodents to die. However, the welfare of all exotic pets relies both on providing optimal nutrition to the predator and ensuring, as much as possible, that their natural behaviours can be expressed. Does that mean that predatory species must be fed live prey? This article discusses this problem and seeks potential solutions.

Salmonella enterica in reptiles of German and Austrian origin.

Captive reptiles are routinely identified as reservoirs of Salmonella spp. and the number of reports about reptile-associated salmonellosis is increasing. In the present study, Salmonella were detected in 86 of 159 (54.1%) faecal reptile samples cultured. The percentage of Salmonella positive samples was significantly lower in turtles as compared with lizards and snakes, as Salmonella were only detected in one sample from a single turtle out of 38 turtles investigated. In all, 42 different Salmonella serovars were found. All isolated Salmonella belonged to the species enterica, predominantly to the subspecies I (n=46) and IIIb (n=30), but also to subspecies II (n=3), IIIa (n=6) and IV (n=2). All isolates were sensitive to the antimicrobials examined. A comparison between the reptile owners indicated that either no Salmonella were found, or that Salmonella could be isolated from all or nearly all animals of the respective owners. A significantly higher percentage of Salmonella positive reptiles was detected in the group of owners who purchase reptiles in comparison with pure breeders. A total of 88.9% of Salmonella isolates were found in samples of reptiles bought in pet shops and 58.8% in samples from wild-caught animals. The high percentage of Salmonella in reptiles in our study confirms the risk for the transmission of the infection to humans.     

Vitamin D and Ultraviolet B Radiation Considerations for Exotic Pets

Vitamin D is an essential hormone that regulates many different functions in vertebrates and can have a protective effect against various disease conditions. Providing exotic pets appropriate access to vitamin D, through the diet, ultraviolet B (UVB) exposure, or a combination of both, is important for veterinarians and exotic pet owners to consider. Although it is commonly thought that most animals derive the vitamin D they need through their diet, there are a number of species that appear to benefit more from UVB exposure. In addition, there has been minimal study to investigate appropriate dietary levels of vitamin D for many of our exotic pets. Although the recommendation of providing UVB lighting has been primarily limited to captive reptiles, research with other species (e.g., birds and small mammals) suggests that these animals may also benefit from this type of lighting. However, the provision of UVB is not without its potential side effects. The purpose of this article is to review the important roles of vitamin D in animals, the different methods animals use to acquire this hormone, the potential clinical signs associated with hypovitaminosis or hypervitaminosis D, the role of artificial UVB lighting in the synthesis of vitamin D, and the potential side effects associated with UVB radiation.     

Causes of disease and death in ornamental fish--frequency and importance]

Between 1986 and 1990 1068 aquarium fishes from breeders, wholesale dealers and pet shops and from private owners were examined. In 45% of the cases different non infectious causes of illness or death were detected. Infectious causes were present in 38%. 14% of the fishes showed no pathologic symptoms, whereas 3% of the samples were unfit for examination. The frequency of infectious and non infectious diseases respectively in fishes from breeders vs. dealers vs. private owners is given. From these results factors of pathogenesis in aquarium fishes are discussed and compared to those in fish breeding for food fish. Advices for prevention of diseases in fancy fishes are given.     

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.

Importation of wild and pet animals at Frankfurt-on-Main airport as an example

In 2000 more than 14,000 consignments of live animals have been checked at the border inspection post at Frankfurt am Main airport, most of them consignments of tropical fish, reptiles and animals for laboratory research. The import of wild or pet animals which could transmit notifiable or human pathogen diseases from third countries into the European Community has been rising continuously during the last years. Various national and community precautions have been taken to avoid the danger of importation of such diseases into the community. A risk analysis on EC-level concerning the transmission of diseases by reptiles, ornamental fish or other pet animals is still overdue.

Cross-sectional survey of pet ownership,veterinary service utilisation,and pet-related expenditures in New Zealand

ABSTRACT

Aims: To describe the demographics of and predictors for pet ownership, reasons for visiting a veterinarian, and pet-related expenditure in pet owners in New Zealand.

Methods: A cross-sectional online survey was conducted from 18–22 June 2015 using a permission-based panel of New Zealand residents aged ≥18 years. Questions included demographics of respondents, number of pets and reasons for owning or not owning pets, number of visits and reasons for visiting a veterinarian, and pet-related expenditure.

Results: Of the 1,572 respondents who completed the survey, 1,013 (64.4%) owned ≥1 pet. Of these, 443 owned dogs, 696 cats, 32 horses, 103 birds, 55 rabbits, and 159 owned fish. Companionship was the most common reason for getting dogs, cats, and birds; horses were mostly owned as a hobby, rabbits to provide fun for children, and fish as a source of relaxation. The majority of dog, cat, and rabbit owners considered their pets to be family members; horse owners almost equally considered their horses a hobby or a family member. The odds of pet ownership increased for respondents from a rural region, having a higher household income, having children and being female. Overall, 711/1,013 (70.2%) pet-owning respondents had taken ≥1 animal to the veterinarian in the previous year, with the most common reasons being for vaccination or annual check-ups or health issues. Respondents who considered their pets trusted companions, had a higher income, and owned dogs or cats compared with other species, were most likely to have taken their pet to a veterinarian. The greatest pet-related expenditure for all species was food. The median yearly veterinary expenditure was $200–499 by dog owners, $100–199 by cat owners, and <$100 by horse, bird, rabbit, and fish owners. The best source of information for pet-related issues was considered to be veterinarians by 724/1,001 (72.3%) owners, and the internet by 509/1,001 (50.8%) owners.

Conclusions: Among survey respondents, pet ownership was common and pets filled a variety of roles in the household. Pet owners reported spending considerable amounts of money on their pets each year, but some of them may be underutilising veterinary services despite veterinarians being considered as valuable sources of information about pet-related issues.     

Common Ophthalmic Problems in Pet Rabbits

As rabbits are becoming more popular as pets and owners are willing to pay for specialized care, veterinary practitioners are required to maintain their expertise treating these animals. In recent years, ophthalmic patients have become an important part of the small mammal pet population. Ocular disorders in pet rabbits can be caused by genetic defects, congenital malformations, traumatic events, infections, housing conditions, and nutritional deficiencies. Knowledge of the species-specific anatomy and physiology forms the basis for the interpretation of findings and prevents misinterpretation of a normal state as an abnormality. The ophthalmic examination of rabbits should adhere to the same principles and techniques used for canine and feline patients, although adjustments are required because of different anatomical and physiologic features. Magnification is necessary for accurate assessment. This article summarizes the common ophthalmic disorders of pet rabbits, especially those that are unique to rabbits.     

Behavior of pet animals

Severe mistakes in pet keeping are often the result of ignorance. Many animals suffer from the care of their owners. Industry provides food in the proper composition, but the importance of the cage's interior, its size and the number of animals of the same species kept in it is often neglected. The key to a better understanding of pets is the knowledge of the ecological environment of their species. Fish, amphibia and reptiles are capable of simple acts of learning, but their potential of adaptation to their environment is determined mainly genetically, which can be observed best during the phase of their youth. Most members of these animal groups are born with a perfect behaviour program. Thus aquaria and terraria should as far as possible correspond to the needs and requirements of the species in question to its ecological niche. An aquarium should be a model of the animals' biotope. The effect of the conditions under which a pet is kept on its wellbeing is discussed in detail for the budgerigar and the guinea pig. Experiments with budgerigars showing that too small cages and the missing company of animals of the same species lead to abnormal behaviour are described. Guinea pigs live in packs. The fact how important the group and its social organization is for the individual guinea pig is documented by experimentally verified data. Furthermore the effect of the guinea pig's ontogeny under experimental conditions on the structure of a pack is discussed. Already small changes in the size of the cage or in its interior encourage the guinea pig's exploration behaviour and its mobility.     

Gastrointestinal Parasites of Urban Dogs in Perth, Western Australia

A study was conducted to determine the prevalence of gastrointestinal parasites in a sample of urban dogs in Perth and the knowledge of their owners about the control and zoonotic transmission of these parasites. Faecal samples (421), collected from dogs originating from five sources, were examined by microscopy and questionnaires administered to dog owners and managers/owners of pet shops. The prevalence of gastrointestinal parasitism was higher in pet shop puppies (51%), than in dogs from refuges (37%), breeding kennels (32.7%), veterinary clinics (15.6%) and exercise areas (5.3%). Protozoa, in particular Giardia, were detected more frequently (22.1%) than helminth parasites. After adjusting for other factors with multiple logistic regression, puppies less than 6 months of age, dogs living in households with more than one dog, and dogs from refuges were significantly more likely to be parasitized. The prevalence of Giardia was found to be directly associated with the number of doses of anthelmintics given in a year, increasing 1.2 times for each dose administered. The majority of owners were aware of the potential risk to human health from canine helminths, however only one third were aware of the means of transmission to humans. It is concluded that veterinarians can play an important role in increasing the level of awareness of canine zoonotic parasites.     

Prevalence of Salmonella spp. in pet reptiles in Japan

From November 2000 to July 2002, 112 fecal samples from pet reptiles, including 18 turtles, 71 lizards and 23 snakes, sold at a pet shop were examined for the prevalence of Salmonella spp. in Japan. Salmonella spp. were isolated from 83 (74.1%) of 112 samples, and a total of 112 Salmonella isolates were identified as subspecies I to IV. The majority of isolates (62.5%) belonged to subspecies I and 54 isolates could be identified as any of 28 serovars. The predominant serovars were found to be S. Bardo, S. Newport and S. Panama, which cause human salmonellosis. These results indicate that pet reptiles may be a potential infectious source of human salmonellosis in Japan.     

Risk factors for pet evacuation failure after a slow-onset disaster.

OBJECTIVE: To determine risk factors for pet evacuation failure during a flood. DESIGN: Cross-sectional survey. SAMPLE POPULATION: 203 pet-owning households in a flooded region. PROCEDURES: Persons under evacuation notice because of a flood were interviewed by use of a random telephone survey. RESULTS: 102 households evacuated with their pets, whereas 101 households evacuated without their pets. Low pet attachment and commitment scores were significantly associated with a greater chance of pet evacuation failure. Risk of pet evacuation failure and lower attachment and commitment scores were also associated with pet management practices prior to the disaster, such as dogs being kept outdoors most of the time or owners not having carriers for their cats. More than 90% of owners made housing arrangements for their pets without assistance. CONCLUSIONS AND CLINICAL RELEVANCE: Predictors of pet evacuation failure are usually present before a disaster strikes and are potentially modifiable. Mitigation of pet evacuation failure should focus on activities that reinforce responsible pet ownership and strengthen the human-animal bond, including socializing dogs, attending dog behavior training classes, transporting cats in nondisaster times, and seeking regular preventive veterinary care. Most pet owners are self-reliant in disasters, and this behavior should be encouraged.
