The aim of the study was the evaluation of the epizootic situation of contagious equine metritis (CEM) in selected horse breeding centers in Poland. In the years 2007-2009, 765 samples collected from 212 horses (83 mares and 129 stallions) were examined. Animals came from the National Stud, stallion’s depot and stud farms, in which procreation was based on natural service or artificial insemination. Swabs for examination were taken from predilection sites of the urinary-genital tract of stallions and mares harbored by Taylorella equigenitalis. Two stallions (0.9% of the examined population) coming from two different breeding centers were identified as CEM carriers. Isolated strains of Taylorella equigenitalis were susceptible to streptomycin, novobiocin, oleandomycin, cefoperazone, neomycin and oxytetracycline. The stallion-carriers were treated, with three sets of samples were taken from each stallion after treatment. Samples were collected every other day, not earlier than 7 days post therapy. The control examinations gave a negative result. The animals were admitted as cured and no longer as carriers of Taylorella equigenitalis.
