Topic:Animal Health
Animal Health encompasses a broad range of topics focused on maintaining and improving the well-being of equine species. This field addresses various aspects of horse care, including disease prevention, diagnosis, treatment, and management of health conditions. Key areas of interest include equine nutrition, vaccination protocols, parasite control, dental care, and the management of chronic conditions such as laminitis and colic. Additionally, animal health research in horses investigates the impact of exercise and training on physical health, the role of genetics in disease susceptibility, and the development of new therapeutic approaches. This page compiles peer-reviewed research studies and scholarly articles that explore the latest advancements, challenges, and best practices in preserving and enhancing the health of horses.
Characteristics of Escherichia coli isolated from septic foals. Fifteen Escherichia coli isolates from the blood and tissue of foals with septicemia were compared with 15 from the feces of clinically normal horses. Comparisons were made with respect to survival in normal equine serum, production of aerobactin, and production of hemolysin. Isolates from the blood and tissues of septic foals were more likely to be resistant to equine serum than were isolates from feces of clinically normal horses. There were minimal differences between the isolates with respect to aerobactin and hemolysin production, almost all being nonhemolytic and aerobactin negative. Ser...
Tissue-specific gene expression as an indicator of epididymis-specific functional status in the boar, bull and stallion. cDNA probes derived from genes expressed specifically in the human epididymis were used to examine gene expression in the epididymides of boar, bull and stallion by Northern hybridization. Two probes for the HE1 and HE4 gene products were found to recognize tissue-specific transcripts in all three species, with a regionally differential distribution within the epididymis. Additionally, antibodies recognizing the HE4 protein were shown to react specifically in the epididymis of the boar and bull. An extensive study of the boar showed that, whereas mRNA for the HE1-homologue was up-regulated mar...
Equine lutropin and chorionic gonadotropin bear oligosaccharides terminating with SO4-4-GalNAc and Sia alpha 2,3Gal, respectively. Equine chorionic gonadotropin (eCG) and lutropin (eLH) are heterodimeric glycoprotein hormones which are synthesized in the placenta and pituitary, respectively. The beta subunits of eCG and eLH, like their alpha subunits, arise from a single gene and have identical amino acid sequences. In contrast, the beta subunits of CG and LH in primates arise from different genes and differ in sequence. We have examined the structures of the Asn-linked oligosaccharides on eCG and eLH. eCG bears di- and tri-branched Asn-linked oligosaccharides terminating with Sia alpha 2,3 or 6Gal beta 1,4GlcNAc. In cont...

Serum concentrations of ormetoprim/sulphadimethoxine in 1-3-day-old foals after a single dose of oral paste combination. Ormetoprim (OMP)/sulphadimethoxine (SDM) combinations
have been used in the treatment of fowl cholera, colibacillosis,
salmonellosis, infectious coryza, and other bacterial infections in
poultry (Mitrovic et al. 1969; Maestrone et al. 1979). The drug
combination has also been used in the treatment of colibacillosis
in neonatal pigs (Brandt and Maestrone 1980) and Pasteurella
pneumonia in cattle (Ames et al. 1987). Serum concentrations and
pharmacokinetics of SDM (Oh-Ishi and Nakajima 1964; Durr et
al. 1980) and OMP/SDM (Brown et al. 1989) after intravenous or
oral administration to ad...
A comparative review of human and equine leucocyte differentiation antigens. Monoclonal antibody technology has allowed the recognition and study of numerous leucocyte antigens in man and laboratory animals for over a decade. Numerous advances in the understanding of immune responses and immunopathology have resulted. In recent years equine researchers have started to develop similar reagents, which now offer a powerful tool to investigators of equine immunology and disease.
Technique for long-term right dorsal colon fistulization in ponies. Right dorsal colon fistulas, 2.5 cm in diameter, were created in 2 healthy ponies, using a 2-stage surgical procedure. The first stage consisted of resection of portions of the 16th and 17th ribs on the right side, followed by surgical creation of a 6- to 8-cm-diameter adhesion between the right dorsal colon and the body wall. Fistulas were created approximately 2 weeks after the first surgery by sharp dissection through the adhesion into the lumen of the colon. The fistulas have been satisfactorily maintained for > 2 years by de Pezzer catheters (45 F). Ponies with fistulas have been used ...
Relationship between locomotor forces, hoof position and joint motion during the support phase of the stride of galloping horses. Three methods were used simultaneously to determine the relationships between the vertical forces exerted on the hooves and the positions of the limbs and hooves at the times of peak vertical forces from 2 horses galloping on a track straightaway. Vertical forces were recorded from an instrumented shoe, fetlock joint motion was measured with an electrogoniometer and the angles of the carpus, fetlock and hoof were determined from slow-motion films. At hoof contact, the mean angles of the carpus and fetlock were 181-182 degrees and 199-206 degrees, respectively. Peak vertical forces on the heel ...
Epizootic of equine influenza in 1969 in Poland. Epidemiological observations on the course and spread of equine influenza in Poland during the 1969 epizootic were carried out. The dynamics of the spread of the disease in the country are shown graphically by voivodship. The disease incidence and mortality rates for the entire country are also shown. The highest incidence of disease and mortality rates were found to be in November 1969. A/equi-2/Warsaw/69 was identified as the causal virus. It caused the largest epizootic in the country since 1954.
The estimation of factor VIII levels in horse, cattle, sheep and pig plasma by the use of synthetic chromogenic substrate. Factor VIII level in horse, cattle, sheep and pig plasma was estimated by the use of synthetic chromogenic substrate S-2222 (benzoyl-isoleucyl-glutamyl-glycyl-arginyl-p-nitronilide). The highest level of this factor was stated in pig, the lowest one in sheep plasma.
Large granular lymphocyte leukemia in a horse. Large granular lymphocytes (LGL) occur as a leukemic or aleukemic neoplasia in humans,(1) rats,(2) cats,(3,4) dogs,(5) and horses.(6) The single case of equine LGL previously reported was aleukemic.(5) In contrast to this previous report of aleukemic equine LGL neoplasia, the leukemia in the case presented here established the antemortem diagnosis of LGL.
Analgesic effects of detomidine in thoroughbred horses with chronic tendon injury. This study was undertaken to assess the analgesia provided by detomidine (20 micrograms kg-1 intravenously) in thoroughbred horses. Pain thresholds to a mechanical noxious stimulus were measured before and after a period of mild chronic pain in one foreleg. Detomidine was a good analgesic in control animals; their pain thresholds were significantly elevated for about 60 minutes. After injury, the injured leg had a significantly lower pain threshold and the intensity and duration of analgesia provided by detomidine were significantly reduced. The analgesia in the opposite (sound) leg was also r...
Laboratory transmission of eastern equine encephalomyelitis virus to chickens by chicken mites (Acari: Dermanyssidae). Pools of adult female chicken mites, Dermanyssus gallinae (De Geer), were allowed to feed on chicks that had been inoculated with eastern equine encephalomyelitis (EEE) virus and that had a viremia level of 10(6.2)-10(6.6) plaque-forming units per milliliter of blood. Virus remained detectable by plaque assay in samples of these mites for 30 d after the infectious blood meal. Virus was not recovered from any of 151 progeny of virus-exposed female mites. Mites that had fed on viremic chicks were allowed to feed on naive chicks 3, 7, 11, 15, or 30 d later. EEE virus was transmitted to chicks by ...
Assay for endogenous heparin in plasma of livestock using a synthetic chromogenic substrate. The levels of endogenous heparin in the plasmas of horses, cows, sheep and pigs were determined with the use of synthetic chromogenic substrate benzoyl-isoleucyl-glutamyl-glycyl-arginyl-p-nitroanilide (S-2222). The lowest heparin concentrations were stated in cattle plasma, the highest ones in the plasma of pigs.
[The occurrence and significance of enterotoxin-producing Clostridium perfringens strains in the intestinal tract of horses]. 100 faecal samples from clinically healthy horses of different age groups and feeding habits, 50 samples of faeces from horses suffering from enteropathy accompanied by diarrhoea and small and/or large intestine from 25 horses that had died after an intestinal disease were examined for the presence of Clostridium (Cl.) perfringens. The frequency with which Cl. perfringens was detected was 22% in clinically healthy horses, 32% in horses with diarrhoea and 52% in the dead horses. In two faecal samples from the horses with diarrhoea the microbial count of Cl. perfringens was ca. 10(6) cfu/g faece...
