| Summary: | Mastitis is a common condition in dairy herds, related to important economical losses for the sector. Additionally, the development of resistance to antimicrobians has been a constant preoccupation in human and veterinary medicine. This study was carried out to identify the causal agents of clinical and subclinical mastitis, and its state of resistance in the presence of some antimicrobial in dairy herds in Duitama (Boyacá). 541 animals were evaluated in production, distributed in 25 farms, 12 with mechanical milking, and 13 with manual milking. Milk samples were taken from the positive quarters of clinical or subclinical mastitis for bacteriological culture and an antibiogram. It was found that the gram positive bacteria are the main cause of mastitis in the area, be-ing the Staphylococcusaureus the causal agent of the most frequent clinical and subclinical mastitis, with per-centages between the 32 to 42% respectively. With less frequency, the Streptococcus sp. was the causal agent for both types of mastitis. As for the resistance state, we observed a relative sensibility to oxacinlin, vancomicin, tetraciclin and streptomicina by the gram positive agents. The results obtained in this study ratify the importance of knowing the mastitis characteristics in each area in order to establish the right treatments. |
