Prevalencia e Incidencia de Mastitis Bovina Mediante la Prueba Decaliforniamastitis Test con Identificación del Agente Etiológico en Paquiestancia, Ecuador

An epidemiological study of the prevalence and incidence of bovine mastitis was carried out in the Paquiestancia community in the Cayambe canton using the California MastitisTest and identification of the etiological agent with microbiological culture tests and antibiograms for antibiotic resistance. The milk sampling was carried out in two stages with an interval of 4 months. 880 mammary quarters were sampled from 220 cows in production in 42 cattle farms. The prevalence (P) in the first stage was 64% and in the second stage 66% with an incidence (I) of 70%. Laboratory results confirmed the presence of the following etiological agents: Staphylococcus intermedius 26%, Staphylococcus aureus 22%, Streptococcus dysgalactiae 13%, Staphylococcus epidermis 13%, Escherichia coli strain 1 13%, Micrococcus 5%, Corynebacterium sp 4%. According to the antibiogram analysis, the animals under study were resident Streptomycin 48%, Amoxicillin 35%, Cephalexin 5%, Tetracycline 4% and Gentamicin 4%. The risk factor that influences the prevalence and incidence of the disease is the lack of application of good milking practices.
