Incidence of respiratory cryptosporidiosis in Georgia broilers: 1987-92.
The temporal incidence of respiratory cryptosporidiosis in Georgia broilers was established for 1987-92. Analyzed data showed that, for some years, the incidence of respiratory cryptosporidiosis was higher in southern Georgia than in northern Georgia. The incidence of respiratory cryptosporidiosis was never higher in northern Georgia than in southern Georgia. Because there was a significant (Z[rho] = 3.02, P = 0.003) relationship between the number of days < or = 0 C and the diagnostic frequency of respiratory cryptosporidiosis in the present study, we concluded that as the number of days below freezing increases, the diagnostic frequency of respiratory cryptosporidiosis in broilers decreases.
