Topic:Public Health
The topic of Public Health and horses encompasses the study of interactions between equine populations and human health systems. It involves examining the transmission of zoonotic diseases, which are diseases that can be transferred between animals and humans, as well as the role of horses in the epidemiology of such diseases. This field also considers the impact of equine-related activities on public health, including injuries and environmental effects. Research in this area often explores preventive measures, management strategies, and policies to mitigate health risks associated with horses. This page compiles peer-reviewed research studies and scholarly articles that investigate the intersection of equine and public health, focusing on disease transmission, risk assessment, and health management strategies.
Prevalence and epidemiology of the major gastrointestinal parasites of horses in Perth, Western Australia. A survey was conducted on the prevalence of the major gastrointestinal parasites in 140 horses necropsied in Perth, Western Australia, during 1979 to 1982. Adult Strongylus vulgaris were found in 22.5 per cent of horses and verminous arteritis in 62.9 per cent. The peak worm prevalence was in November to January (summer). S edentatus had a similar prevalence and seasonality but S equinus was not found in this survey. Draschia megastoma and Habronema muscae were found in 66.2 per cent and 35.3 per cent of horses respectively. Infection is probably acquired in summer when 8 per cent of the Musca...
The development of the canadian veterinary profession. A proposal for the development of Canadian veterinary education and of the organization of the profession is described. There should be one veterinary school with four branches (the current colleges). A student would train at any college in comparative medicine for two and one-half years and then train for 12 months or more in a specialty taught at one or more colleges. These specialties are general veterinary practice, poultry practice, public health and regulatory medicine, ruminant practice, swine practice, equine practice, small animal practice, fish medicine, fur-bearing and exotic animal...
Common plasmid encoding resistance to ampicillin, chloramphenicol, gentamicin, and trimethoprim-sulfadiazine in two serotypes of Salmonella isolated during an outbreak of equine salmonellosis. An outbreak of equine salmonellosis occurred at the Veterinary Medical Teaching Hospital, University of California, Davis, between June 1981 and March 1982. Forty-four horses were infected with Salmonella saint-paul, a serotype rarely isolated from animals at the university before the outbreak. Unlike the isolates of S saint-paul obtained at the beginning of the outbreak, almost all strains isolated near the end were resistant to ampicillin, cephalothin, chloramphenicol, gentamicin, kanamycin, sulfadiazine, trimethoprim, and trimethoprim-sulfadiazine. A conjugal-resistance plasmid (R-plasmid) ...
An outbreak of equine influenza at a harness horse racetrack. An outbreak of an influenza-like illness affected approximately 1/3 of the 1050 race horses stabled at a standardbred racetrack and resulted in a 3-day suspension of racing. A/Equi-2 influenza virus was isolated from 1 affected horse and 8 of 10 horses sampled seroconverted. Threshold protective levels of HI antibody against A/Equi-2 influenza virus were not demonstrated in unaffected horses. Resistance in unaffected horses was assumed to result from other factors following previous exposure. Few of the horses had been vaccinated against equine influenza. It was felt that an outbreak of this m...
Serologic surveillance for vesicular stomatitis virus on Ossabaw Island, Georgia. Seventeen species of mammals and seven species of birds from Ossabaw Island, Georgia, were tested for vesicular stomatitis (VS) neutralizing antibodies. Seropositive results were restricted to mammals with six of 17 species testing seropositive for VS (New Jersey type) neutralizing antibodies. Seropositive species included: raccoons (Procyon lotor), white-tailed deer (Odocoileus virginianus), feral swine (Sus scrofa), cattle (Bos taurus), horses (Equus caballus), and donkeys (Equus asinus). All tests for VS (Indiana type) were negative.
Antibiotic susceptibilities of Salmonella species isolated at a large animal veterinary medical center: a three year study. The antibiograms of 408 Salmonella species isolated from large animals were collected during a three year study from 1981 through 1983. The predominant Salmonella serogroup among these isolates was group B. A consistently high percentage of all isolates were resistant to ampicillin and tetracycline. A pattern of increasing resistance to chloramphenicol and gentamicin was documented for serogroup B isolates while the susceptibility of the isolates to neomycin increased. There was a decrease in the incidence of susceptibility to sulfamethoxazole-trimethoprim among the group E isolates. These cha...
Animal welfare considerations – pastoral animals. Modern pastoral farming has radically transformed the niche where agricultural animals live. Recent trends in husbandry tend to give as much emphasis to economic profit and human convenience, as do a concern for the farmed species. Most of the traditional ways of handling sheep, cattle, goats, horses and pigs, like castration, ear tagging, tail-docking or horse breaking, have been accepted by the public with little concern. Inevitably, as renewed public interest focuses on intensive farming, some questions are directed towards extensive pastoral farming practices, particularly in newly-farmed ...
Community people-pet programs that work. Excellent models exist for people-pet programs in institutions and in the community. Veterinarians should assess the needs of their local communities and adapt a model program to fit these needs.
The use of an animal-baited net trap for collecting mosquitoes during western equine encephalitis investigations in Argentina. A large net trap was used to sample mosquito populations attracted to horses at three sites each in Santa Fe and Rio Negro Provinces, Argentina, during the austral summer of 1984. These provinces, as well as others in Argentina, were affected by a severe epizootic of western equine encephalitis (WEE) during 1982-83. Totals of 2,752 and 6,929 mosquitoes were collected in Santa Fe and Rio Negro Provinces during five and three trap nights, respectively. Culex mosquitoes of the subgenus Culex were predominant (45.8% of total) in the Santa Fe collections, although Aedes albifasciatus also was preva...
[Vaccination of animals and human health]. Prophylactic immunization of animals against obligat and nonobligat pathogenic zoonoses benefit human health in many ways both directly and indirectly. Typical examples of a direct protective effect are the vaccinations of dogs, cats and foxes against rabies as well as the vaccinations against respiratory diseases in cows, horses, dogs and cats to which the most varied species of pathogens of noncompulsory zoonoses contribute. A considerable contribution to the protection of human health is made by the vaccination against salmonellosis and leptospirosis, against vesicular stomatitis, American ...
[Chronopharmacokinetics of phenylbutazone in the horse. Application to antidoping control]. Chronopharmacokinetics of intravenous phenylbutazone in the horse was studied with the aim of antidoping control. Among parameters studied, the single one which seemed to depend on circadian rhythm was the elapsed time between the injection and the plasmatic peak. There was no relationship between the injection time and the both parameters: half-life and time required to reach the forensic level of 4 micrograms/ml. This later, and oxyphenbutazone/phenylbutazone ratio, should depend on individual factors. Therefore, the injection time should not be a main parameter for the phenylbutazone evalua...
The prevalence of Toxoplasma gondii antibodies in man in Plateau State and meat animals in Nigeria. Toxoplasma gondii antibodies were found in the sera of 22.86% of people in the Jos area of Plateau State, Nigeria. The incidence of antibodies in Nigerian food animals was 17.40%, the highest being in sheep (21.92%) and lowest in goats (13.88%). Cattle and horses were roughly equally infected--about 17.0%. The zoonotic potential of T. gondii in food animals is stressed and epidemiological factors are reviewed.
[Flavivirus: serological survey in horses from the Tandil area]. Sera from 282 equines from Tandil country and surroundings were investigated searching for hemagglutination inhibition (HI), Complement fixation (CF), and Neutralizing (NT) antibodies against three flavivirus:Ilheus, St. Louis Encephalitis, and Yellow Fever from the Togaviridae family. Sera were collected between 3-20-79 and 11-25-80 from 10 different places in Tandil and Ayacucho countries. Animals ranged from 45 days to 27 years old. Forty nine of them reacted with one or more flavivirus by HI and/or CF tes representing a prevalence of 17.4% for this antigenic complex. Twenty four of them ne...
Case-control study of risk factors associated with isolation of Salmonella saintpaul in hospitalized horses. In an investigation of a 1981-1982 outbreak of nosocomial Salmonella saintpaul infection in hospitalized horses at the University of California Veterinary Medical Teaching Hospital in Davis, California, a case-control study was performed using data gathered from the records of 33 cases and 132 controls. Multiple logistic regression risk analysis was used to identify factors associated with isolation of the organism, controlling for the effects of other, possibly confounding variables. Horses receiving parenteral antibiotics were at 10.9 times greater risk of having S. saintpaul isolated than w...
“The grave yawns for the horseman.” Equestrian deaths in South Australia 1973-1983. The fatalities associated with the riding and handling of horses in South Australia over the 11-year period 1973-1983 are reviewed. There were 18 deaths, including two sudden natural deaths in the saddle and one drowning. The 15 cases of horse-related trauma represent a death rate of approximately one per million population per annum. Thirteen of the deaths were the result of a head injury after a fall. Nine persons were not wearing protective headgear. The two principal groups at risk were male professional riders with a mean age of 32 years and female amateurs with a mean age of 19 years.
Clinical and pathological studies of brain injuries in horse-riding accidents: a description of cases and review with a warning to the unhelmeted. We present a clinical and pathological study of brain injuries in horse-riding accidents. Among six fatal cases, all experienced riders varying in age and sex, two were not wearing helmets and four had inadequate protective headgear. Among five non-fatal cases, four wore adequate helmets and only one of these suffered permanent neurological damage. The fifth was not wearing a helmet and although he eventually returned to work, a CT scan following the fall showed a deep-seated perithalamic hematoma. These findings are consistent with those of virtually all other studies in that they suggest tha...
