Abstract This study was conducted to investigate the prevalence of subclinical mastitis and its contagious environmental bacterial causes in dairy cows Jos Metro polis Plateau State. A total 208 milk samples were collected aseptically from 52 lactating subjected California Mastitis Tests (CMT). Milk transferred into peptone water broth for enrichment, followed with bacteriological assays bioche...

This study was conducted to investigate the prevalence of subclinical mastitis caused by Staphylococcus spp. in ewes in West-Azerbaijan province of Iran. Molecular characterization of isolated Staphylococcus spp. from diseased ewes were performed using polymerase chain reaction (PCR) followed by restriction fragment length polymorphism (RFLP) and DNA sequencing of glyceraldehyde-3-phosphate deh...

California mastitis test (CMT), direct leukocytes counts and bacteriological examination were performed on 630 milk samples from apparently healthy mammary glands of dairy goats comprising a mixed population of German Alpine, Toggenberg, Saanen and Galla crosses to find the prevalence of subclinical mastitis. The prevalence of subclinical mastitis was 9.8% according to CMT, 9.7% according to di...

In present study, the polymorphism at five microsatellite loci BM302, BM4505, BMS2684, CYP21 and DIK20 were investigated for finding their association with the somatic cell counts (SCC) in crossbred cattle. Total 130 animals were tested using california mastitis test (CMT) and somatic cell count (SCC) to screen animals for mastitis. Total 83 alleles were found in all five microsatellites where ...

An outbreak of subclinical mastitis in a flock of 620 milking sheep was investigated. Microbiological and epidemiological analyses identified the causative agent as belonging to the Burkholderia cepacia complex (formerly Pseudomonas cepacia). Every ewe in the milking flock was individually tested for subclinical mastitis on two separate occasions, 6 weeks apart, by the California (rapid) mastit...

The present work is a large epidemiological study aiming to detect the prevalence of subclinical mastitis and to investigate the major udder pathogens in Jalisco State, western Mexico. For this purpose, 2205 dairy cows, representing 33 Mexican dairy herds, were involved. Of 2205 cows, 752 mastitic animals were diagnosed and only 2,979 milk samples could be obtained for further investigation. Al...

Mastitis is an important disease of dairy cows, and it causes huge economic losses to farm owners due a decrease in milk production, reduction quality, increase the cost cow treatment. A crosssectional study was conducted Southern Ethiopia’s Silte zone from October 2020 June 2021 aimed estimate mastitis prevalence, assess related risk factors, identify prevalent bacterial causes. Three hundred ...

A cross sectional study was carried out from November 2016 to April 2017 in and around Asella town to determine the prevalence, associated risk factors and antimicrobial susceptibility of Staphylococcus aureus in Bovine mastitic milk. A total of 384 lactating dairy cows were screened for mastitis based on clinical examinations and California Mastitis Test (CMT). Out of 230 lactating crossbred c...
