    Abstract:
    This study was carried out to investigate the effect of infection with Campylobacter fetus subsp. venerealis (Cfv) on the pattern of lectin binding in the uterus and oviduct of heifers. Cfv persistence was demonstrated by bacterial isolation and immunofluorescence. Infected animals showed variations in the lectin binding pattern when compared with control animals. Cfv-infected heifers showed an increased expression of galactose and N-acetyl-galactosamine in the endometrial glands (PNA and SBA binding, respectively). The oviductal epithelium of infected heifers was strongly positive for Con A, which indicated the presence of alpha-D-mannose and alpha-D-glucose. The results of this study showed that Cfv-infection modifies the lectin binding pattern in the reproductive system of heifers. Modifications in glycoconjugates may be involved in failures of fertility and/or implantation.
