The aim of the research project was to determine the Etiologic Agent of caprine
mastitis and bacterial resistance of animals to different antibiotics. The research was
conducted in a goat-fold of the company la Pampilla, located in the parish Yaruqui,
province of Pichincha; and on small and medium farms producing goat's milk in the
parish of Mira, Carchi province.The results of the study were 45% of the samples
taken in Pichincha and 24% in the province of Carchi presented values > 700000
CCS/mL, outside the normal range according to the NTE INEN 2624 of 7,0 x 105
CCS/cc. As for the hygienic quality, in the province of Pichincha we found 5% and
in the province of Carchi 4%, of cases with values > 800000 CFU / cc, outside the
ranges established by the norm.For microbiological analysis, presented low counts in
cases; in the samples of the province of Pichincha, (27%) were positive to
Coagulase-negative staphylococci; while in the province of Carchi (3%) it was
Staphylococcus intermedius and (44%) Coagulase-negative staphylococci. In the
analysis of susceptibility for the detection of bacterial resistance of goats, it was
noted the following; in the province of Pichincha showed resistance by 27% for
Benzylpenicillin, 13% Ampicillin, 3% Tetracycline; in the province of Carchi
showed resistance by 29% to Ampicillin, 28% Benzylpenicillin, 2% Cefotaxime, 2%
Chloramphenicol, 2% Trimethoprim/sulfamethoxazole and 2% Tetracycline.
