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.
Onchocerca cervicalis infection in horses from the western United States. In a study of Onchocerca cervicalis infection in a sample of 100 horses from the western United States, 48 were infected. Infection was more common in older horses and occurred in both sexes equally. Data about the distribution and the concentration of microfilariae within the skin are presented. The only cutaneous pathologic change that could be attributed to microfilariae was minimal perivascular inflammatory cell infiltrate. Invasion of the eye with microfilariae occurred in 60 percent of the infected horses. An attempt was not made to relate microfilarial invasion of the eye with ocular pa...
[False-positive results obtained on examining slaughtered animals for the presence of antibiotic residues (author’s transl)]. As part of the examination of emergency-slaughtered animals for the presence of antibiotic residues, studies were done to see whether false-positive results would be obtained when the Sarcina lutea kidney test and Bacillus subtilis BGA test were performed. When the S. lutea kidney test was positive in cattle, calves and swine, penicillin was invariably found to be present in those animals, the histories of which showed that they had not been given antibiotics. A syringe and an injected fluid containing penicillin residues are regarded as possible causes of these positive results. When the S. l...
Sequelae of Venezuelan equine encephalitis in humans: a four year follow-up. The purpose of this study was the identification of possible sequelae of the infection of human individuals with Virus of Venezuelan Equine Encephalitis (VEE). Special emphasis was laid on exploring neurological, psychological and behavioural aspects and particularly on the search for a possible association of the disease with epileptic phenomena, brain damage and/or mental deficiency. A four-year period of observation was conducted on a sample of children from El Carmelo (Colombia) where an epidemic of VEE took place in 1967. A group of seven children who presented the encephalitic type of th...
[Prevention of tetanus in man and animal following injury]. The effect of heterologous and homologous antitoxin is the same if an equal amount of antitoxin is present in the organism. In man there are no circulating antibodies in the blood after the first injection of the toxoid because there is no natural immunity against the tetanus antigen. After the second injection, man develops the same immunity as animals. Large antitoxin doses protect people for a longer period than small doses. Normally 3,000 I. U. of the heterologous antitoxin protects people for 2 to 3 weeks. In man and sheep 2 ml of the adsorbed vaccine produces an earlier and longer-lastin...
Tetrachlorodibenzodioxin: an accidental poisoning episode in horse arenas. Tetrachlorodibenzodioxin was identified as the apparent cause of an outbreak of poisoning in humans, horses, and other animals. Exposure was related to the spraying of contaminated waste oil on riding arenas for dust control. The contamination resulted from improper disposal of a toxic industrial waste. The pathologic effects and chemical identification of tetrachlorodibenzodioxin are described.
A serologic survey of pronghorns in Alberta and Saskatchewan, 1970-1972. To determine the exposure of free-ranging pronghorns (Antilocapra americana Ord) to selected pathogens, serum samples were obtained from 33 live-trapped animals from southwestern Saskatchewan in 1970, and from 26 and 51 animals from southeastern Alberta, in 1971 and 1972, respectively. Antibodies were found to the agents of parainfluenza 3, bovine virus diarrhea, eastern and western encephalomyelitis, infectious bovine rhinotracheitis and the chlamydial group. No serologic reactors were found to the agents of bluetongue, epizootic hemorrhagic disease, brucellosis, or leptospirosis (4 serotypes...
[The cologne riding course for the blind. Original information on a didactic-methodical approach (author’s transl)]. Since November 1973 a riding course has been carried out with six blind adults. Due to the instructional methods the participants were able to ride independently, without an attendant, after only 30 hours. The effects of riding on the blind encompass coordination training and development of muscle strength. Furthermore, riding has a pronounced influence on the circulatory system. This attractive reaction activity provides the person who, as a result of his specific handicapping condition is limited in both the spatial and social fields, with an expansion of his living space and sphere of exper...
[Effect of tranquilizer doping on the muscular activity of the sport horse. II. — Diazepam (author’s transl)]. The practise of repeated doping of the sport horse led us to examine its effects on the health of the animal, and particularly on muscular activity. The main doping agent used at present (acepromazine) has already been studied (COURTOT et al., 1974). In this paper, we study the secondary effects of diazepam, a derivative of the benzodiazepine series, which is being used more and more frequently on horses. In treated animals as compared to controls, we observe: -- a slight respiratory depression related solely to effort, -- an increase in seric creatine phosphokinase rate with no apparent relat...
Investigations on the presence of antibodies to several alphaviruses in humans and domestic animals of a region with elevated epidemiological potential. The paper reports on serological results obtained by HAI tests against several alphaviruses - eastern equine encephalitis (EEE), western equine encephalitis (WEE), Chikungunya, Midlebourg, Semliki Forest, Sindbis, and Ilheus viruses - carried out in humans and some domestic animals in a region with an intensive circulation of migratory birds. It was possible to detect in human antibodies to EEE, WEE, and Sindbis viruses, but in very low proportions (1.8%, 0.4%, and 0.6%, respectively). Serological results obtained in animals were practically negative: antibodies to EEE virus were found only in...
