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 study was designed to investigate the effect of mastitis on various components including fat percentage, protein, total solids, solid not fat, pH, specific gravity and lactose content in milk cross-bred (Holstein Friesian × Cholistani) Sahiwal cattle. A 376 samples (excluding blind nonfunctional teats) from 100 cows (50 50 sahiwal) were collected aseptically. Animals different ages,...

Bovine Mastitis is an inflammation of the mammary gland, usually due to microbial infection, which causes economic loss dairy producer every year. Staphylococcus one most common pathogens responsible for contagious mastitis in bovines. The aim this study was identify coagulase positive Staphylococci isolated from bovine subclinical mastitis. In vitro biofilm forming ability isolates, important ...

Susceptibility to mastitis is in part determined by genetics. Opportunities exist for genetic improvement of resistance to mastitis but currently available means for genetic selection are limited and focus mainly on EBV for SCC and, in countries with health recording, on EBV for clinical mastitis. Further opportunities exist to incorporate available EBV for udder conformation and milking speed ...

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...

The primary objective of this study was to assess the antibacterial sensitivity pattern of Coliforms isolates from clinical and sub-clinical mastitis to quinolones. Forty coliforms isolates from bovine clinical and subclinical mastitis were tested for antimicrobial susceptibility by measuring MIC by Resazurin dye broth microdilution method. Of the 27 E. coli isolates tested, only 7.4% of the is...

In this investigation, some epidemiological studies were run on subclinical mastitis for totally 350 dairy cows of different breeds, ages and distributed in different villages in Assiut governorate, Assiut, Egypt, along a whole year (during the period from June 2006 till July 2007) through field screening surveys by using of the California mastitis test (CMT) for each quarter milk sample follow...

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...

The objective of this study was to compare the results of an on-farm test, named Somaticell, with results of electronic cell counting and for milk somatic cell count (SCC) among readers. The Somaticell test correctly determined the SCC in fresh quarter milk samples. Correlation between Somaticell and electronic enumeration of somatic cells was 0.92 and kappa coefficient 0.82. Using a threshold ...

The aim of the study was to evaluate the slime-producing ability of coagulase-negative staphylococci (CNS) isolated from clinical and subclinical mastitis in cows. The study was carried out on 100 isolates of CNS obtained from milk of 86 cows from farms located in the Lublin region (Poland). Slime-producing ability was observed in over half of coagulase-negative staphylococci (54.0% of isolated...
