Contagious equine metritis (CEM), a highly contagious bacterial venereal infection of equids, caused by Taylorella equigenitalis, is of major international concern, causing short-term infertility in mares. Portugal has a long tradition of horse breeding and exportation and until recently was considered CEM-free. However, in 2008, T. equigenitalis was isolated at our laboratory from a recently i...

The objectives of this presentation are to review results of our previous and on-going research with respect to the risk factors and consequences of poor reproductive performance in dairy cows, and to develop an economic framework to optimize decisions related to dairy cow reproductive performance. To make profitable breeding and replacement decisions, the farmer must account for factors includ...

Abstract It has been established that the development of metritis in cows after providing obstetric aid as a result abortion, eversion uterus or retention placenta is accompanied by an increased microbial and fungal background uterus. Without during delivery, only from 5… 9 days birth, 35.37% had genitals contaminated with various pathogenic microflora. Already on third day puerperia, 14 specie...

The objective was to unravel the peripartum immune and metabolic changes associated with metritis in Holstein cows. cows (n = 128) had blood collected at −14, 0, 3, 7 d relative parturition (DRP). Flow cytometry used evaluate leukocyte counts, proportions, activation. Total cells, live cells (LiveDead-), single monocytes (CD172α+/CD14+), polymorphonuclears (PMN; CD172α+/CD14-/SSChigh), B-cells ...

The objective of this study was to develop a method to quantify antimicrobial drug usage and treatment practices on conventional and organic dairy farms that had been recruited to represent a broad spectrum of potential exposure to antimicrobial drugs. Data on disease prevalence and treatment practices of organic (n = 20) and conventional (n = 20) farms were obtained during a farm visit using a...
