The aim of this study was to determine the prevalence of bovine mastitis and the antimicrobial resistance of the pathogens involved in a dairy region of Colombia. Mammary quarters of 348 cows were examined and evaluated using the California Mastitis Test(CMT). CMT-positive samples were cultured for bacteriological isolation and susceptibility to antibiotics by the disk diffusion method. Descriptive statistics and prevalence ratio were calculated. The results indicate that 158 (45.4%) of the cows were positive for CMT. Clinical mastitis was found in seven cows (2.0%) and subclinical mastitis in 151 cows (43.4%). The coagulase-negative staphylococcus (CNS) group was the main pathogen found in 46.7% of the isolates, followed by Staphylococcus aureus (31.1%) and Streptococcus spp (20.7%). Klebsiella pneumoniae and E. coli had a low occurrence (0.5%). CNS, Staphylococcus aureus and Streptococ...

El objetivo de la investigación fue determinar la prevalencia de mastitis bovina y la resistencia antimicrobiana de los patógenos involucrados en una región lechera de Colombia. Los cuartos mamarios de 348 vacas fueron examinados y evaluados mediante la prueba de California para el diagnóstico de mastitis (CMT). Las muestras positivas a CMT se cultivaron para el aislamiento bacteriológico y susceptibilidad a antibióticos mediante el método de difusión en disco. El análisis de los resultados se realizó mediante estadística descriptiva y relación de prevalencia. Los resultados indican que 158 (45.4%) de las vacas fueron positivas para CMT. Se encontró mastitis clínica en siete vacas (2.0%) y mastitis subclínica en 151 vacas (43.4%). El grupo estafilococo coagulasa-negativo (SNC) fue el principal patógeno encontrado en el 46.7% de los aislamientos, seguido de Staphylococcus ...

The aim of this study was to determine the post-vaccine response of canines and felines of the municipality of San Sebastián de Mariquita, Colombia, which presented in 2014 a fatal case of canine rabies due to atypical bat variant. A cross-sectional and non-experimental sampling by convenience was carried out on 130 canines and 38 felines from the rural and urban area of ​​the municipality. Blood samples were taken. The anti-rabies antibody titration was done using the ELISA kit (Platelia Rabies II Kit Ad Usum Veterinarium) approved by the OIE for the detection and titration of IgG antibodies against the glycoprotein of the virus. The classification categories (protection status) were established as Protected (> 0.5 IU/ml), Insufficient protection (>0.1 - <0.5 IU/ml) and Unprotected (<0.1 IU/ml). Results showed that 40% (52) of the canines obtained titles corresponding t...
