The use of analgesic drugs by South African veterinarians

According to a survey, non-steroidal anti-inflammatory agents were the most popular analgesic used in South Africa for management of peri-operative pain, acute post-operative pain and chronic pain. The most popular non-steroidal anti-inflammatory agents are flunixin meglumine and phenylbutazone. The most popular opioid type drug is buprenorphine, followed by morphine. In the peri-operative setting, analgesic agents were not actively administered to 86.3% of cats and 80.7% of dogs. Analgesic premedications were frequently administered, e.g. xylazine or ketamine, but no specific drug was administered for post-operative pain. Veterinarians need to critically review their anaesthetic and analgesic practices in order to achieve balanced anaesthesia.     

Legal responsibilities of veterinarians in the control of zoonotic diseases

This discussion of legal issues that may arise from the existence of zoonotic diseases is not meant to cause alarm; rather, it is meant to alert members of the profession to possibilities, not probabilities. The very nature of any discussion of legal issues, especially a discussion of case law in which someone is always suing somebody else, exaggerates the true-life situation. Although it is everyone's hope that they will not be involved in litigation, it is wise to be aware of the problems that may arise in connection with zoonotic diseases.     

Skills required of dairy veterinarians in western Canada: A survey of practicing veterinarians

This study determined skills required of entry-level veterinarians for dairy practice in western Canada and compared mixed and dairy practitioners in the skills that they perform. We surveyed western Canadian veterinarians involved in dairy practice, focusing primarily on clinical activity of respondents. Response rate was 39.4% (281/714). Respondents were classified as either mixed practitioners (< 10% time in dairy practice) or dairy practitioners (> 75% time in dairy practice). For both groups, individual animal medicine and surgery skills were performed more commonly than herd health skills. The most important skills identified were those required for basic theriogenology, physical examination, treatment of common disorders, and general surgery. These results underscore the continued importance of individual animal skills in food animal practice in western Canada.     

A survey of the risk of zoonoses for veterinarians

The objectives of this study were to identify factors associated with zoonotic infections in veterinarians, the incidence of physician consultation and treatment and the incidence of diagnostic and treatment errors. Veterinarians in any area of practice were solicited to participate in an online survey through an invitation letter sent to the Oregon Veterinary Medical Association. Proportions of respondents to various factors were analyzed for differences among gender, age, time since graduation and type of practice in which they worked. In all, 216 complete responses were received. In all, 13.9% of respondents had never been vaccinated against rabies, and 20.8% had been exposed to suspect rabid animals, mostly (64.4%) a single time. Other zoonoses were reported by 47.2% of respondents: mostly diseases transmitted via contact (57.4%) especially ringworm, followed by those with oral transmission (21.7%). Most zoonotic infections were reportedly acquired by young veterinarians working in primary care veterinary practice. Cats were the species most commonly reported as the animal source of a zoonotic infection. Veterinarians likely self-diagnosed zoonotic diseases, especially those transmitted by contact. Medical care providers were consulted for diagnosis of more serious diseases. Diagnosis and treatment errors were uncommon. Results of this study emphasize the need to educate future veterinarians during their early years in veterinary school about the risks associated with their future jobs.     

A survey of antimicrobial use during bovine abdominal surgery by western Canadian veterinarians

Members of the Western Canadian Association of Bovine Practitioners were surveyed regarding their use of antimicrobials in bovine abdominal surgery. Perioperative antimicrobials were used in 100% of abdominal surgeries by 96 of 98 respondents. Although postoperative administration was the most common perioperative period for antimicrobial use, intraoperative intraperitoneal use was reported by more than half of the veterinarians surveyed. Procaine penicillin G and oxytetracycline were the most commonly administered perioperative antimicrobials.     

Efficacy of training in theriogenology as determined by a survey of veterinarians

OBJECTIVE: To determine whether veterinarians perceive that theriogenology training at veterinary medical schools in North America and the Caribbean is adequate for achievement of theriogenology skills commonly used in private practice. PROCEDURES: A survey was mailed to members of the veterinary medical associations of Alabama, Kansas, Pennsylvania, and Washington. With regard to reproductive procedures in bovine, equine, porcine, small ruminant, camelid, and small animal species, veterinarians (predominantly practitioners) were asked to rate the importance of that procedure in their job and to assess their own degree of competency in that procedure at the time of their graduation from veterinary school. RESULTS: Procedures considered most valuable in practice were those that represent basic theriogenology education and training, such as transrectal palpation of cows and mares and interpretation of vaginal cytologic specimens in bitches. Dystocia management was a high priority in all species. Correlations between rankings for value in practice and competency at graduation were good, varying from 0.75 in cattle and 0.78 in horses to 0.98 in dogs and 1.0 in cats, small ruminants, and pigs. CONCLUSIONS: Analysis of these data suggests that appropriate theriogenology procedures are being taught in veterinary medical schools but perhaps not to the extent required to achieve adequate competency immediately at graduation. Issues requiring further investigation include the effect of tracking in the veterinary curriculum on theriogenology training, methods by which more students could receive greater practical exposure during theriogenology training, and the apparent relative lack of theriogenology training (including contraception) in small animals and exotic animals.     

A survey of reproductive success in South African Thoroughbred horse breeding from 1975 to 1999

The data and an analysis of the statistical summaries from the 'Return of Mares' of the General Stud Book of The Jockey Club of Southern Africa from 1975-1999 are presented. The total number of mares covered per season ranged from 7393 (1992) to 5180 (1995). The total living produce in the period surveyed was 95 317 foals. The categories of data examined include: the total number of mares covered per season; the total numbers and percentage of their living produce; the total numbers and percentage dead produce, 'slips' and foals born dead, barren and 'no return' mares; and the total number of live twins reported. The percentage live foals per season increased from 52 to 62% and the percentage barren and 'no return' mares declined from 35.50 to 28.40% over the period surveyed. The number of live twins reported showed a dramatic reduction from 156 to 5. These apparent improvements are ascribed to a combination of factors including advances in veterinary knowledge and technology. The findings are similar to those reported by similar surveys of national Thoroughbred populations from North America and Germany. There is an indication to broaden this annual survey by recording additional parameters more accurately reflecting reproductive efficiency rather than a cumulative annual total of live foals.     

Demographic survey of veterinarians employed in western Canada

The objective of this study was to generate demographic data on veterinarians working in western Canada. A sample of 551 veterinarians was randomly selected from a population of 2474 veterinarians employed in western Canada, 425 (77.1%) of whom responded to the survey. The respondents were evenly split between males (53.1%) and females (46.9%). More than half (58.0%) of the private practitioners practised exclusively on companion animals (small animals and horses), while 2.9% devoted 100% of their time to food animals. There were 351 respondents who had had ≥ 2 employers since graduation; 80% of those who had begun their careers in companion animal (CA) practice had remained in this type of practice, while 54.3% of those who had begun their careers in mixed animal practice had switched to CA practice. Analyses of wage and workload data from 85 full-time veterinary employees showed that CA practitioners worked the fewest hours/week (47.0), had the least number of evenings on-call/month (3.7), and earned the highest hourly wage ($35.79) as compared with non-CA practitioners.     

Carriage of methicillin-resistant Staphylococcus pseudintermedius in small animal veterinarians: indirect evidence of zoonotic transmission

Methicillin-resistant Staphylococcus pseudintermedius (MRSP) is increasingly reported in small animals and cases of human infections have already been described despite its recent emergence in veterinary practice. We investigated the prevalence of MRSP and methicillin-resistant Staphylococcus aureus (MRSA) among small animal dermatologists attending a national veterinary conference in Italy. Nasal swabs were obtained from 128 veterinarians, seven of which harboured MRSP (n = 5; 3.9%) or MRSA (n = 2; 1.6%). A follow-up study of two carriers revealed that MRSP persisted for at least 1 month in the nasal cavity. Methicillin-susceptible S. aureus (MSSA) was isolated from 32 (25%) conference participants, whereas methicillin-susceptible S. pseudintermedius (MSSP) was not detected, suggesting that MRSP may have a particular ability to colonize humans compared to MSSP. All isolates were characterized by spa typing. Methicillin-resistant isolates were further typed by antimicrobial susceptibility testing, SCCmec and multi-locus sequence typing. Two lineages previously associated with pets were identified among the five MRSP isolates; the European epidemic clone ST71-SCCmec II-III and ST106-SCCmec IV. One of the two MRSA isolates displayed a genotype (ST22- SCCmecIV) frequently reported in dogs and cats. MRSP isolates were resistant to more antimicrobial agents compared with MRSA isolates and displayed the typical multidrug resistance patterns of MRSP in pets. The 32 MSSA isolates belonged to 20 spa types and the most frequent types (t12, t15 and t166) were associated with common S. aureus lineages in humans (CC30 and CC45). Although low, the 3.9% MRSP carriage rate found among small animal dermatologists was surprising in consideration of the rare occurrence of S. pseudintermedius in humans, the lack of MSSP detection and the recent appearance of MRSP in Europe. As cases of human MRSP infection have been linked with pets, veterinarians should be aware of this zoonotic risk and proper preventative measures should be taken to avoid MRSP transmission from animal patients.     

Molecular detection of zoonotic tick-borne pathogens from ticks collected from ruminants in four South African provinces

Ticks carry and transmit a remarkable array of pathogens including bacteria, protozoa and viruses, which may be of veterinary and/or of medical significance. With little to no information regarding the presence of tick-borne zoonotic pathogens or their known vectors in southern Africa, the aim of our study was to screen for Anaplasma phagocytophilum, Borrelia burgdorferi, Coxiella burnetii, Rickettsia species and Ehrlichia ruminantium in ticks collected and identified from ruminants in the Eastern Cape, Free State, KwaZulu-Natal and Mpumalanga Provinces of South Africa. The most abundant tick species identified in this study were Rhipicephalus evertsi evertsi (40%), Rhipicephalus species (35%), Amblyomma hebraeum (10%) and Rhipicephalus decoloratus (14%). A total of 1634 ticks were collected. DNA was extracted, and samples were subjected to PCR amplification and sequencing. The overall infection rates of ticks with the target pathogens in the four Provinces were as follows: A. phagocytophilum, 7%; C. burnetii, 7%; E. ruminantium, 28%; and Rickettsia spp., 27%. The presence of B. burgdorferi could not be confirmed. The findings of this study show that zoonotic pathogens are present in ticks in the studied South African provinces. This information will aid in the epidemiology of tick-borne zoonotic diseases in the country as well as in raising awareness about such diseases in the veterinary, medical and tourism sectors, as they may be the most affected.     

Educational preparedness of veterinarians for foreign animal diseases

Veterinary medical education in FADs has been and will continue to be critically important if veterinarians are expected to fulfill the profession's primary obligations to society--those of protecting our animals' health, conserving our animal resources, and promoting public health. It is imperative that curricula and instruction in veterinary schools and colleges provide the depth and breadth of knowledge and understanding necessary to prepare all veterinarians, including those in private practice, for their key role in defending against FADs. Development and implementation of governmental and military programs to diagnose, prevent, control, and eradicate FADs will require a dedicated cadre of public sector veterinarians who have a solid educational foundation in FADs and understand the contemporary issues and global challenges we face. Animal-related industries, associations, and organizations will increasingly rely on well-educated veterinarians to help guide them in ways that will protect animals, clientele, consumers, and trading partners from effects of FADs. Agencies and organizations concerned with conservation of animal resources will require veterinary expertise necessary to prevent FADs in a multitude of animal species, including marine animals, wildlife, endangered species, zoologic specimens, and important genetic lines as well as our domestic companion and livestock species. Species affected by FADs also include human beings for those disease agents with zoonotic potential; thus, veterinary education also plays a key role in public health.     

A survey of farmers'' attitudes to services provided by consulting veterinarians to the Western Australian sheep industry

A postal survey was conducted of 80 sheep farmers in the Kojonup and Esperance districts of Western Australia to establish what they wanted from a veterinary service. Twenty five of the farmers surveyed used a sheep consultant, 25 did not, and 30 were interested in employing one. Farmers were asked questions about themselves and their attitudes to private veterinarians who provide specialist services to sheep farmers. Data reported here showed that farmers wanted a veterinarian who lived in the district, was well trained in sheep management and production, was enthusiastic and had good communication skills. The service provided should be whole-farm and available to members of the consultant's group only. Regular newsletters and field days were necessary, but the provision of contract services, such as mulesing, lamb-marking, drenching, pregnancy testing and sheep classing, and 'fire-brigade' services for sick animals, were not rated as important. Most farmers were unwilling or unable to give a dollar value for the likely benefits of a consultancy service. Non-financial benefits included keeping farmers up to date with new technical developments and information. The survey also showed that a veterinarian specialising in services to sheep farmers could be confident of employment.     

Occurrence of avian Schistosomatidae (Trematoda) in South African birds as determined by a faecal survey

The abundance, prevalence and distribution of avian Schistosomatidae in South African birds has been estimated by means of a survey for parasite eggs in faecal samples. Eight types of eggs were recovered, mostly from members of the Anatidae and Laridae and these have been assigned to the following schistosome genera: Austrobilharzia (1), Gigantobilharzia (1), Trichobilharzia (5) and Ornithobilharzia (1).     

A historical overview of African American veterinarians in the United States, 1889- 2000

The annals of veterinary medical history rarely mention the presence of African American veterinarians and other minorities. Between 1889 and 1948, records show, a meager 70 African Americans graduated from veterinary schools in the United States and Canada. It was not until the veterinary school at Tuskegee (Institute) University was established in 1945 that a significant increase in the number of African American veterinarians occurred in the United States, and over the ensuing years their participation in every facet of the profession has been striking. Their employment in various areas of the profession and their successful performance in the workforce have done much to dispel stereotypical perceptions about minorities. Despite demographic data indicating that the United States is moving rapidly toward a multicultural society, recruitment programs to increase the number of African American students and faculty at the 27 US veterinary colleges have not kept pace with the declared goals of ethnic diversity. If the needs of a changing culture are to be met, veterinary medical education must look toward more ethnic inclusion in the student body and faculty. To that end, the Iverson C. Bell Symposium has consistently advocated the adoption of new and creative methods for increasing minority student enrollment and expanding faculty opportunities in the nation's veterinary colleges.     

A preliminary biochemical genetic survey of four South African painted reed frog (Hyperolius marmoratus) populations

Allozyme electrophoresis was used to evaluate genetic variability in painted reed frog (Hyperolius marmoratus) populations from the Northern Province and the Eastern Cape. Sixteen protein-encoding loci were resolved, of which seven displayed allelic polymorphism. Average heterozygosity (H) values in two permanent H. m. taeniatus populations from the Northern Province (7.9% and 6.3%) did not differ substantially from each other nor from the geographically distant Eastern Cape H. m. verrucosus (9.1%). An isolated Northern Province H. m. taeniatus population displayed more polymorphism than any other group with H=14.1%, which can probably be attributed to the periodic influx of reed frogs following dry periods. Genetic distances and gene diversity (F_ST) values conformed with expected values for conspecific populations. The results attained concur with the hypothesis of increased genetic heterogeneity among populations of small and relatively sedentary animals     

A survey for small animal veterinarians regarding flea and tick control pesticide products

The Canadian Veterinary Medical Association administered a survey to capture the clinical experiences of small animal veterinarians regarding adverse effects observed in cats and dogs following the use of flea and tick control pesticide products. Results of this survey are discussed and compared with pesticide incident reports collected by Health Canada.
