ABSTRACT: Seven dairy cattle farms from eastern Antioquia were tested for mastitis in a cross-sectional study with a non-probabilistic convenience sampling procedure. Each udder quarter of 290 lactating cows was evaluated through the California Mastitis Test in order to determine the prevalence of subclinical mastitis. Milk from positive quarters underwent somatic cell count (SCC), cell culture and antibiotic sensitivity tests. The prevalence of subclinical mastitis per quarter was 19.9% (228 quarters). Only 11 quarters (0.95%) had clinical mastitis. The average SCC for all quarters was 1,105,733 cells/mL. Streptococcus dysgalactiae was the most common bacteria observed (29.5%) in the 226 cultures evaluated, followed by coagulase negative staphylococci (CNS, 23%), and Staphylococcus aureus (10.3%). The frequency of contagious pathogens and environmental pathogens was 37.8% and 49.3%, respectively. This study confirms that mastitis remains elevated in this region, suggesting a continuous lack of milking hygiene and education of farm personnel. |

Se evaluó cada cuarto de 290 vacas en producción láctea mediante la realización del California Mastitis Test (CMT) con el fin de determinar la prevalencia de mastitis por cuarto y por vaca. A la leche proveniente de los cuartos positivos mayores a trazas, se les realizó recuento de células somáticas (RCS), cultivo y antibiograma. La prevalencia de mastitis subclínica por cuarto fue de 19.9% (228 cuartos) y 11 cuartos (0.95%) presentaron mastitis clínica. El promedio del RCS para todos los cuartos fue de 1.105.733 céls/ml. En los 226 cultivos, Streptococcus dysgalactiae fue la bacteria más común (29.5%), le siguieron estafilococos coagulasa negativo (ECN) (23%) y Staphylococcus aureus (10.3%). La frecuencia de patógenos contagiosos fue 37.8%, entre tanto que la de ambientales fue 49.3%.COL0001262application/pdfspaUniversidad de Antioquia, Facultad de Ciencias AgrariasCENTAUROMedellín, Colombiainfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_2df8fbb1https://purl.org/redcol/resource_type/ARTArtículo de investigaciónhttp://purl.org/coar/version/c_970fb48d4fbd8a85Atribución-NoComercial-CompartirIgual 2.5 Colombia (CC BY-NC-SA 2.5 CO)info:eu-repo/semantics/openAccesshttps://creativecommons.org/licenses/by-nc-sa/2.5/co/http://purl.org/coar/access_right/c_abf2https://creativecommons.org/licenses/by-nc-sa/4.0/Prevalencia de mastitis en siete hatos lecheros del oriente antioqueñoPrevalence of mastitis in dairy herds in Eastern AntioquiaRev.
