A serologic survey of Mycoplasma putrefaciens infection in goats.
The prevalence of Mycoplasma putrefaciens infection in goat populations in Mendocino and Sonoma counties of northern California was studied, using the plate and tube agglutination tests. On a county basis, Mendocino had a higher antibody prevalence (13%) than Sonoma (10%). The overall antibody prevalence among the 377 goat serum samples tested was 11%. There was no statistical evidence to show any significant difference in prevalence on the basis of herd size. Of the common goat breeds in California, the American La Mancha had the lowest prevalence (4.7%), the Toggenberg, highest (10.8%). Angora goats shipped from Texas showed a much higher prevalence (67%) than any of the California breeds. The age-specific risk calculations indicate that all age groups were more susceptible to M putrefaciens than 4-year-old goats, with the lowest prevalence of 3.8%. The highest prevalence (21.3%) was observed in the Angora goats. Males had a lower prevalence (10.7%) than females (16.1%). A flock of sheep included in the survey showed a prevalence of 15%.
