Rose Bengal coloured antigen was found to be more sensitive than Tetrazolium coloured antigen. The result indicated that there is an equal spread of infection in all the districts of Tamil Nadu and the incidence was more in organised farms than rural areas. Breed. sex and age wise analysis indicated that high graded white and black cattle, females and animals aged above 6 years are more susceptible to brucellosis.EnglishVeterinary ScienceArticle
