Resumen:
The bovine tritricomonosis is a venereal disease caused by the protozoan Tritrichomonas foetus that produces embryonic death and abortion. The protozoan strains isolated from different herds in the country differ in their pathogenicity in Balb/c mice. In the pathogenesis of the disease, cell adhesion mediated by the protozoan surface glycoconjugates and host cells is very important. In a previous work, we reported that the labelling intensity of SBA and PNA lectins increased in luminal and glandular epithelia of the uterus of mice infected with T. fetus. The aim of this work was to confirm whether these changes are dependent on the strain of the inoculated protozoa. We used preputial smegma samples of bulls from Berker, Laprida, San Cayetano, Bolivar and Tres Arroyos, which were inoculated intravaginally in Balb/c mice. Five weeks after inoculation mice were sacrificed. Samples of uterine horns were processed for lectinhistochemistry and incubated with SBA and PNA lectins. In animals infected with the isolation from Bolivar the affinity for both lectins in luminal and glandular epithelia of the endometrium clearly increased. There is a partial relationship between the lectin binding pattern and the previous data obtained on the pathogenicity of the different strains.T. fetus.
