The Prevalence of mastitis and its relation with vitamins E and A serum levels and microbiological status in dual purpose creole cows, in summer season
Mastitis is an infectious disease of cows. The presence of mastitis is due to various factors such as the geographical area, climate, periods of drought, nutrition, hygiene, among others.

Mastitis, THI, Vitamina A, Vitamina E, Estatus Microbiológico. Mastitis is an infectious disease of cows. The presence of mastitis is due to various factors such as the geographical area, climate, periods of drought, nutrition, hygiene, among others. The objective of this study was to determine the prevalence of subclinical mastitis in dual-purpose cattle under grazing conditions, through the microbiological status of milk and its association with serum levels of vitamins E and A during the summer in ranches neighbouring the rural community of Cobachi, Sonora. Five hundred four milk samples were collected from the four quarters of 126 cows, for microbiological culture and to evaluate catalase, coagulase, and oxidase tests. The isolates were tested for antimicrobial sensitivity by the Kirby-Bauer method (disk-diffusion on agar). Vitamin A and E were analyzed by HPLC chromatography. Serum values of vitamin A and E, 5.58 and 0.59 µmol/L respectively, were found lower than normal and did not correlate with mastitis. Mastitis prevalence was 65.80%, and Gram-positive species in clusters, as well as coagulase and catalase-positive and oxidase negative, suggests that is gender Staphylococcus sp. Furthermore, ceftriaxone was an antibiotic that shows more resistance. A high prevalence of subclinical mastitis not associated with vitamins and deficiencies of vitamins E and A was found in summer is concluded. La mastitis es una enfermedad infecciosa de las vacas y se debe a diversos factores, como la zona geográfica, el clima, periodos de sequía, nutrición e higiene en ordeña principalmente. El objetivo del estudio fue determinar la prevalencia de mastitis subclínica en ganado de doble propósito en pastoreo a través de microbiología en leche y su asociación con niveles séricos de las vitaminas E y A durante el verano en un ejido aledaño a la comunidad rural de Cobachi, Sonora. Quinientos cuatro muestras de leche correspondientes a los cuatro cuartos de 126 vacas se analizaron para el cultivo microbiológico para las pruebas de catalasa, coagulasa y oxidasa. La sensibilidad antimicrobiana de los aislamientos se realizó por el método de Kirby-Baue. La vitamina A y E fueron analizadas por cromatografía HPLC. Los valores séricos de vitamina A (5.58 µmol/L) y E (0.59 µmol/L) fueron menores a los normales y no correlacionados (P>0.05) con mastitis. Se encontró una prevalencia del 65.80% y especies Gram positivos en racimos, coagulasa y catalasa positiva; oxidasa negativa que suponen del género Staphylococcus sp. La ceftriaxona fue el antibiótico al cual mostraron resistencia. Se encontró una alta prevalencia de mastitis subclínica no asociada a las vitaminas y también deficiencias de vitaminas E y A en verano.
