Bovine Trichomonosis (BT, Tritrichomonas foetus) and Bovine Genital Campylobacteriosis (BGC, Campylobacter fetus ssp. fetus and veneralis) are sexually transmitted diseases that cause important economic losses. Improper or no application of the diagnostic protocol would be responsible for the low efficiency in the health control. The objective of this work was to compare the standard techniques versus seroprevalence in a bovine roundup of Santiago del Estero. Preputial scrapes and extraction of serum of 145 bulls were made. BGC was detected by direct immunofluorescence and BT by culture and observation under the microscope. Seroprevalence was conducted by "spot-blotting", using as antigens homogenates from each pathogen and the obtained sera. According to the standard technique, 20.7% BGC and 5.5% BT were estimated. Seroprevalence values were 94.5% (Cf veneralis); 98.6% (Cf fetus) and 80% (T. foetus). The latter indicated a strong presence of disease in the herd coinciding with high reproductive losses reported in the rodeo (~ 40%). However, the standard diagnostic yielded much lower values. The lack of standardization of technology or its misapplication partly account for the under-diagnosis of these pathologies. Seroprevalence provides important information that allows thedetermination of the presence of pathogens, its use being significant in rodeos with no previous health checks for adequate planning and increased productivity.
