ABSTRACT Zebu and Holstein x Zebu crossbred have low incidence of uterine infection when compared to Holstein cows. Resistance to uterine infections may be associated with the ability to recognize invading microorganisms. Endometrial transcription of microbial molecular patterns receptors has been investigated in the postpartum period of Holstein cows, but it is completely unknown in Zebu or Holstein x Zebu cows. In this study, 9 Gyr and 12 F1 Holstein x Gyr cows were submitted to endometrial biopsies at the first and seventh days postpartum, with the objective to measure transcription levels of toll-like receptors (TLRs) 1/6, 2, 4, 5, and 9; nucleotide-binding oligomerization domain (NOD)-like receptors 1 and 2; and coreceptors cluster of differentiation...

The aim of this study was to evaluate the endometrial inflammatory response of nine Zebu cows inoculated through uterine infusion with 30 mL of inactivated Escherichia coli suspension (1 x 109 UFC/mL) and nine with 30 mL of sterile phosphate buffered saline. Endometrial biopsies were performed before and after the inoculations during estrus, and ten days later in the diestrus phase. Neutrophilic infiltrates were observed in 88.8% of samples from the E. coli group in estrus phase and demonstrated different degrees of endometrial inflammation. This study characterizes a suitable model for studying endometritis in cattle.
