Adhesion of Tritrichomonas foetus to bovine vaginal epithelial cells.
An in vitro culture system of bovine vaginal epithelial cells (BVECs) was developed to study the cytopathogenic effects of Tritrichomonas foetus and the role of lipophosphoglycan (LPG)-like cell surface glycoconjugates in adhesion of parasites to host cells. Exposure of BVEC monolayers to T. foetus resulted in extensive damage of monolayers. Host cell disruption was measured quantitatively by a...
متن کاملTritrichomonas foetus damages bovine oocytes in vitro.
Tritrichomonas foetus is an extracellular parasite of the urogenital tract in cattle. It causes infertility and abortion, but there is no documented information on the susceptibility of bovine oocytes to the parasite, except by one article that claimed no effects of T. foetus on oocytes or embryos. The aim of the present study was to study the effects provoked by T. foetus when in interaction w...
متن کاملTritrichomonas foetus induces apoptotic cell death in bovine vaginal epithelial cells.
Tritrichomonas foetus is a serious veterinary pathogen, causing bovine trichomoniasis, a sexually transmitted disease leading to infertility and abortion. T. foetus infects the mucosal surfaces of the reproductive tract. Infection with T. foetus leads to apoptotic cell death of bovine vaginal epithelial cells (BVECs) in culture. An affinity-purified cysteine protease (CP) fraction yielding on s...
متن کاملAntibody enhances killing of Tritrichomonas foetus by the alternative bovine complement pathway.
The role of bovine antibody and complement in host defense against Tritrichomonas foetus was measured by using an assay of trichomonad viability based on protozoal uptake of tritiated adenine. Moderate killing was measured in the absence of antibody only with high concentrations of complement-preserved hypogammaglobulinemic bovine serum. However, very low concentrations of hyperimmune serum pro...
متن کاملAntibody responses of cattle immunized with the Tf190 adhesin of Tritrichomonas foetus.
The antibody response patterns of cattle after subcutaneous and intranasal immunizations with adhesin Tf190 of Tritrichomonas foetus were investigated. Reactions of antibody from cattle parenterally immunized with Tf190 revealed antigen specificity and Tf190 sensitization in the majority of the animals, as determined by Western blotting. The results also demonstrated strong preimmune immunoglob...
