Congenital defects in domesticated animals: general considerations. A mass survey of the distribution of congenital defects in various types of livestock was made possible by the processing by the Veterinary Medical Data Program (VMPD) of standard observations collected on 137, 717 patients seen at veterinary college clinics between Mar. 1964 and Jan. 1969. A total of 6455 animals with 1 or more congenital defects was found. The data were analysed according to species, institution and organ system. Pigs had the highest proportion of congenital defects, cats the lowest. Over all, the systems most frequently involved were the musculo-skeletal and urogenital. The...
Growth of the equine infectious anemia virus in a continuous-passage horse leukocyte culture. A continuous-passage horse leukocyte culture [V.B. 40, abst. 4672] was susceptible to the virus of equine infectious anaemia, as determined by cyto-pathic effect and viral titre. Ultrafiltration studies indicated that the virus was less than 32 mμ in diameter, which agrees with previous reports. Susceptible horses developed clinical signs and lesions of the disease when they were inoculated with both unfiltered and ultrafiltered culture virus.
Critical tests of activity of dl-tetramisole against the internal parasites of horses. Single doses of tetramisole were evaluated in nine critical tests with horses (2.2, 5 and 10 mg/kg given s/c and 20 and 30 mg/kg given by mouth). Parascaris equorum was removed (83 to 100%) by all of the doses, and 98% of Strongylus vulgaris were removed by the two largest doses. The largest doses removed only 38-54% of S. edentatus, while the dose of 30 mg/kg removed 74% of small strongyles. Results against mature Oxyuris equi were variable, and only 13% of immature oxyurids were removed at 30 mg/kg. There was no effect on Gastrophilus intestinalis and G. nasalis. Toxicosis occurred only in t...
Plasma concentrations of cortisol and corticosterone in the normal horse. The plasma concentration of cortisol and corticosterone in the normal horse was determined by competitive protein-binding analysis (radiostereoassay). The mean plasma concentration of the 2 steroids in resting horses was 5.12 μg./ml., with standard deviation of 1.67 μg. There were no significant differences in the mean values according to age, sex, and pregnancy. Seemingly, diurnal variations in concentrations of the steroids existed in horses; values were high in the morning and low in the evening. Plasma values were increased in horses given corticotropin (acth) and were decreased in those...
