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.
A survey of Clostridium perfringens enterotoxin antibody in human and animal sera in western Canada. Sera from human, cattle, sheep, swine, and horse populations in western Canada were tested for the presence of Clostridium perfringens enterotoxin antibody by the passive hemagglutination (PHA) test, supplemented by an immunodiffusion test and by counterimmunoelectrophoresis. A total of 224 human, 345 cattle, 165 sheep, 620 swine, and 768 horse serum samples were examined. Low-titer reactions in the PHA test were detected in human, cattle, horse, and swine sera, in that order, with no titers demonstrated in sheep. The titers in human sera ranged up to 1:128 and three of these samples were also...
An epidemic of Getah virus infection among racehorses: isolation of the virus. During the autumn of 1978 a disease characterised by fever and occasionally by exanthema and/or oedema of the limbs was seen in approximately 13 per cent of horses in a training stable in the Kanto district of Japan. A virus was isolated by the intracerebral inoculation of one-day-old mice from blood and nasal swabs taken from naturally and experimentally infected horses. The virus was subsequently passaged in two monkey kidney cell lines in which it produced complete cytopathic changes. Infected horses developed neutralising, complement fixing and haemagglutinin inhibiting antibodies to the v...
Leptospirin – an intradermic test for the diagnosis of leptospirosis. IN the State of Bahia (Brazil) the leptospirin produced in Germany for experimental use by the Institute for Veterinary Medicine, Federal Health Office, Berlin, was administered to humans and animals in order to diagnose leptospirosis in collaboration with this Institute. The results were compared with the microscopic agglutination reaction. The total number of test persons or animals was 268; this group included 81 human patients. 60 heads of cattle, 50 goats, 40 pigs, 25 horses, and 12 dogs. All were tested serologically and simultaneously the intracutaneous test was carried out. This test w...
Equine salmonellosis: a review. Salmonellosis in Equidae occurs sporadically throughout the world; the incidence recorded ranges from less than 1 per cent to as much as 27 per cent. In 1976 there was a significant increase in disease and mortality caused by salmonellosis in horses in Britain and treatment was less successful than with other species. Data revealed a general progressive shift away from species specific salmonella serotypes towards the ubiquitous but less discerning strains of Salmonella typhimurium. The role of predisposing causes is assessed and treatment, prevention and zoonitic importance commented upon.
Serological studies on leptospirosis in domestic animals in Quebec. During a period of 30 months, from January 1977 to June 1979, Leptospira agglutinins were detected in 355 (6%) of 5841 bovine sera, 52 (10.1%) of 511 porcine sera, one (5%) of 20 equine sera and one (12.5%) of eight canine sera. Bovine, porcine and equine sera reacted predominantly with L. pomona. Reactors to L. hardjo/sejroe, L. icterohaemorrhagiae and L. grippotyphosa were also detected in cattle. One porcine serum reacted with L. grippotyphosa and one canine serum with L. icterohaemorrhagiae. Al the sera originated from suspected cases of leptospirosis.
Environmental exposure to Coxiella burnetii: a sero-epidemiologic survey among domestic animals. The prevalence of agglutinating serum antibodies against Coxiella burnetii, the cause of Q fever in humans, was tested in a hospital population of companion animals and livestock in California during 1973--1975. A sample of stray dogs was also tested. Among the hospitalized animals 346 (48%) of 724 dogs, 7 (9%) of 80 cats, 9 (32%) of 28 cattle and 31 (26%) of 121 horses had antibodies against C. burnetii. Of 316 stray dogs 208 (66%) were seropositive. The overall prevalence of 53% among 1040 dogs tested was comparable to the 63% antibody prevalence found in an earlier survey among coyotes and ...
Water hardness in relation to cadium accumulation and microscopic signs of cardiovascular disease in horses. The hardness of drinking water (i.e., the sum of calcium and magnesium concentrations) has been related to cadmium concentration in kidney cortex and to microscopic signs of arteriosclerosis and focal myocardial fibrosis in 50 Swedish horses slaughtered for meat production. A significant negative correlation was found between water hardness and cadmium concentrations in kidney cortex. This indicates that horses living in soft water areas are more inclined to accumulate cadmium from the general environment. Microscopic changes in the aorta and myocardium were approximately 2 times as frequent i...
Salmonellosis in a group of ponies: failure to identify a chronic active carrier. Three of 33 ponies died after the herd had been moved to a new environment 3 months earlier. One mare died without premonitory signs of illness. Shortly thereafter, a 5-day-old foal and a 2-year-old gelding died after brief illness. Although cultures were not performed on the mare, Salmonella typhimurium was isolated from the feces and tissues of the foal and gelding. Lesions in the foal were confined to ecchymotic hemorrhages on the mucosal surface of the colon and petechial hemorrhages in the splenic capsule, with adhesions to the parietal peritoneum. The gelding had evidence of severe typhl...
Eastern equine encephalomyelitis in Panama: the epidemiology of the 1973 epizootic. In late June 1973, a small outbreak of equine encephalitis caused by eastern equine encephalomyelitis (EEE) virus occurred in the Republic of Panama. At least 100 horses were affected by the disease and 40 died. More than 1,700 human sera were obtained from areas of virus activity but no serological evidence for infection was found. Four isolates of EEE virus were recovered, one of which was from a small pool of Culex taeniopus mosquitoes. Serologic studies of infected horses and classification by the short incubation hemagglutination-inhibition tests revealed that these isolates were South Am...
[Findings on an epidemic of human trichinelliasis verified in Italy]. The present article completes the information already given in previous papers (Mantovani et al., 1976; Bellani et al., 1977; Mantovani, 1978) and is connected with the research on the infection of horses by Pampiglione et al. (1978). In September 1975 an epidemic of Trichinellosis involving at least 89 people was reported at Bagnolo in Piano (Reggio Emilia). This present article describes the epidemiological investigations. In the introductory part, the Trichinellosis outbreaks are summarized which were reported in Italy during this century along with research on domestic and wild animals. Th...
Survey on antibody to Getah virus in horses in Japan. A seroepidemiological survey was performed on antibody against Getah virus in horses in Japan by the complement fixation test. The positive rate was 35 and 53% in two areas where an outbreak of the infectious disease was reported, whereas it was in a range of 3.3 to 24.2% in other areas, except in certain prefectures of the Kyushu district where a high positive rate was observed. In the Hokkaido district, the northernmost part of Japan, no reactors were found in horses under 6 years old, unlike in any other district. It was also suggested that Getah virus infection might have already been prev...
Persistence in nature of influenza virus A/eq/Praha/56 (Heq1Neq1). Equine influenza occurred in Czechoslovakia 14 years after the last epizootic in horses that had returned from abroad. Six strains A (Heq1Neq1) antigenically related to, but not identical with, strain A/eq/Praha/56 were isolated from 10 washings. Seroconversion was demonstrated with paired sera, but the antibody increase was more marked against the newly isolated strain.
