Topic:Equine Diseases
Equine diseases encompass a wide range of health conditions that can affect horses, including infectious diseases, metabolic disorders, and genetic conditions. These diseases can impact the overall health, performance, and well-being of horses. Common equine diseases include equine influenza, equine herpesvirus, laminitis, and equine metabolic syndrome. Diagnosis and management of these diseases often require a combination of clinical evaluation, laboratory testing, and appropriate treatment strategies. This page gathers peer-reviewed research studies and scholarly articles that explore the etiology, pathophysiology, diagnosis, and treatment options for various equine diseases, providing valuable insights for veterinarians and researchers in the field.
Isolation of the contagious equine metritis organism from colts and fillies in the United Kingdom and Ireland. Between January 1978 and August 1982 the streptomycin resistant strain of the contagious equine metritis organism (CEMO) was isolated from 15 colts and two fillies in the United Kingdom and Ireland. A first season stallion was also suspected of having initiated an outbreak of contagious equine metritis (CEM) at the beginning of the 1982 breeding season. A detailed investigation of the breeding history of the dams and sires of each positive individual indicated that in a number of cases the CEMO was acquired either in utero or following transmission at the time of parturition. In several other ...
Blood groups in animals. The membrane of RBC is literally peppered with a great variety of antigenic determinants (blood factors). Some are fixed genetically, ie, they occur on the RBC of all members of the species under study. Others segregate genetically, ie, they occur on the RBC of some but not all members of the species under study. It is these segregrating determinants that form the blood groups proper, the classic example being blood factors A and B of the ABO system of human blood groups. The number of blood group determinants varies considerably between species (eg, greater than 80 in domestic cattle to only ...
In vitro blastogenesis of equine lymphocytes by inactivated equine adenovirus type 1 antigen. An inactivated equine adenovirus type 1 (EAdV1) vaccine was administered to 4 horses. The horses had virus-neutralizing (VN) antibody titers before they were vaccinated, but developed higher VN antibody titers in response to vaccination. Nonvaccinated control horses did not show increases in VN antibody during the study, indicating that any increase in antibody titer in vaccinated horses was a result of vaccination and not due to an EAdV1 epizootic during the study. Specific EAdV1 in vitro lymphocyte blastogenesis (LB) was evaluated, using lymphocytes from 4 vaccinated and 2 control horses. Ho...
Microsporum equinum in North America. Microsporum equinum was isolated in Ontario, Canada, from five human and two equine cases of ringworm infection. This dermatophyte was previously recovered from North American horses on several occasions, but was considered to be M. canis. We regard M. equinum as distinct from M. canis. It can be differentiated from M. canis by the smaller size of its macroconidia, its failure to perforate hair in vitro, its poor growth and sporulation on bromocresol purple casein dextrose agar, and its incompatibility with Nannizzia otae, the telemorph of M. canis.
Radiographic and arthroscopic findings in the equine stifle. The radiographic and arthroscopic findings in the equine stifle were compared. Survey radiography, contrast arthrography, and arthroscopy were performed on both stifles of 10 horses. Nine of the horses were euthanatized to evaluate the effects of the techniques on the joints. Techniques for double-contrast arthrography and arthroscopy were developed, and the findings were compared. Survey radiography identified only osseous structures. Double-contrast arthrography of the femoropatellar joint demonstrated articular surfaces of the trochlea, patella, and joint capsule. Those of the femorotibial ...
The prevalence of Gasterophilus intestinalis in horses in northern England and Wales. The stomachs of 448 horses from northern England and Wales were examined for Gasterophilus larvae, and 237 (52.7%) were found to be infected with G. intestinalis. Larvae were present in stomachs examined during each month of the year except August. Second instar larvae occurred from September through February and third instars were present from November through July. Adult fly activity began in August as indicated by the presence of eggs on horses. The life-cycle of G. intestinalis in northern England and Wales is outlined from the data presented. The mean instar burdens were 15.7 second and 3...
Electrocardiographic changes in induced hyperkalemia in ponies. In 11 crossbred ponies, hyperkalemia was induced by acute intracardiac infusion of a 0.4M solution of potassium chloride. The ECG changes noticed can be assigned to 4 stages: (1) a widening and a lowering of amplitude followed by inversion and final disappearance of the P wave; (2) an increase in the amplitude of the T wave; (3) an increase in the QRS interval, with some irregularity in the ventricular rate; and (4) periods of cardiac arrest that became terminal or were followed by ventricular fibrillation. At plasma potassium values of greater than 7.5 mM/L, the T-wave amplitude and duration ...
