Susceptibility of horses to Mycobacterium paratuberculosis. The susceptibility of horses to Mycobacterium paratuberculosis was studied. A total of 8 colts was used: 2 colts were exposed intravenously and 1 colt used as a contact control was placed with them; 2 colts were exposed intragastrically; 1 colt was administered killed M. paratuberculosis intravenously; and the remaining 2 colts were used as normal controls and were housed separately. Colts administered live bacilli intravenously began losing weight 84 days after exposure, and shortly thereafter they had clinical signs of disease, consisting of loss of body weight and rough coat. The exposed co...
Survey of histoplasmin skin test reactions among horses in Mexico. In a 3-month period, 2,221 Mexican horses were skin tested for sensitivity to Histoplasma capsulatum antigen. The prevalence of reactivity was 7.9%. There was little evidence of a difference in geographic distribution of sensitivity. The prevalence of reactivity increased with age of the horse. This increment with age is thought to be a function of time exposure to the organism and possibly of selective survival of the horses.
