Protection of the mammary gland against mastitis-causing pathogens is mediated by many factors in thegland and blood circulation. The professional phagocytic cells of bovine udder, polymorphonuclearneutrophils (PMN) and macrophages, comprise the first line of defense against invading mastitis pathogens.Most researchers now accept that the PMN is a key factor in the cows’ defense against intrama...

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...

Escherichia coli is one of the main pathogenic agents causing inflammatory infections in the bovine udder. Here, we report the draft genome sequences of two strains isolated from different cases of clinical mastitis.

The present study was conducted to isolate and identify the major causing bacteria from mastitis milk sample collected from Kerala veterinaryUniversity Livestock Farm, Mannuthy. A total of fifty milk samples were collected from mastitis affected animals and microbiological testing of raw milk was done. Upon microbiological testing the major causing bacteria Staphylococcus aureusand Escherichia ...

Pseudomonas aeruginosa is one of the causative pathogens of bovine mastitis. Most P. aeruginosa strains possess the type III secretion system (TTSS), which may increase somatic cell counts (SCCs) in milk from mastitis-affected cows. Moreover, most of P. aeruginosa cells can form biofilms, thereby reducing antibiotic efficacy. In this study, the presence and effect of TTSS-related genotypes on i...

Escherichia coli is an important bacterial species isolated from bovine mastitis. The rate of neutrophil recruitment into the mammary gland and their bactericidal activity largely affect the severity and outcome of the disease. Ketosis is a common metabolic disease, and affected dairy cows are known to have increased risk for mastitis and other infectious conditions. The disease is associated w...

Streptococcus (Strep.) agalactiae is one of the major pathogens of bovine mastitis and is the main cause of subclinical infection. This study attempted to develop a rapid PCR diagnosis procedure using milk samples collected on filter paper disks. Chromatographic filter paper was employed as the preservation media and kept at room temperature for one to four weeks. The revival rate of Strep. aga...

The effect of enrofloxacin and alfa tocopherol on the capacity of bovine milk leukocytes to generate reactive oxygen species and phagocytic activity after stimulation with phorbol 12-myristate 13-acetate (PMA) for superoxide were studied in bovine clinical mastitis. Group I, consisting of 9 healthy cows, served as the control, whereas groups II and III each contained 9 cows with clinical mastit...

Coagulase-negative staphylococci (CNS) are the predominant cause of bovine intra-mammary infections. They can lead to chronic infections and were reported to significantly increase milk somatic cell counts. The goal of our study was to determine the species distribution and antimicrobial susceptibility profiles of CNS in bovine mastitis milk samples in Switzerland. Between March 2011 and Februa...
