[Toxoplasmosis studies in cattle by serological methods]

2037 cattle sera from seven breeding farms were analysed by SF and KBR methods. 27.29 % positive results were obtained by SF method and 8.94 % by KBR methods. The distribution of titres is shown in table VI. Race and age have no effect on toxoplasmosis infection. Positive findings varying from 1828-43-48 % were obtained in different regions which meant the effect of geografical factor. It is concluted that these differences were due to the cats, found in the government farms which spread the disease. It was observed that toxoplasmosis caused abortions, complicated still birth deliveries, post natal mortality. The SF and KBR methods were applied separately on cattle with or without clinical syndroms. It was found that the more acute cases showed higher titres.
