Bacterial endometritis in mares is one of the main problems in equine reproduction. Due to inadequate diagnoses, antibiotic treatments generally fail, increasing the cases of infertility in females. The present study was carried out with 90 mares which presented signs of subfertility such as abortions, placental retention, repetition of jealousy, vulvar secretion, among others; They were diagnosed by clinical reproductive examination, ultrasound, microbiological culture using the uterine swab technique, and an antibiogram was performed in which the sensidisks of procaine Penicillin G, Gentamicin, Ceftiofur, Cefquinoma, Amikacin and Ampicillin were evaluated. According to the results obtained in the microbiological laboratory, it was found that E. coli was the bacterium that grew most frequently with 21.11 % (19/90), followed by Staphylococcus spp. 11.11 % (10/90). In the isolation of E. coli it was found that the bacteria showed a greater sensitivity to amikacin, followed by ceftiofur and cefquinoma; In turn, Staphylococcus spp was more sensitive against antibiotics such as ceftiofur and cefquinoma. The large negative spectrum bacterial agents presented high percentages of sensitivity with respect to antibiotics such as amikacin, ceftiofur, cefquinoma and gentamicin.
