Mastitis is the most common and economically significant disease affecting dairy cattle. A variety of bacteria can be isolated from bovine mastitis cases. and are the most common causes of contagious and environmental clinical mastitis, respectively. Antimicrobial therapy is commonly implemented for mastitis prevention and control. Unfortunately, despite the best possible antimicrobial treatmen...

The prevention of bovine mastitis is the most important component of a mastitis control program, and both preand postmilking teat antisepses are the most effective procedures for preventing new intramammary infections (IMI) in dairy cows. These procedures involve dipping teats of dairy cows before and after milking with an appropriate germicidal preparation to reduce teat skin colonization and ...

A highly efficient and stereocontrolled synthesis of an aminooxy derivative of the tetrasaccharide repeating unit of a rhamnose-rich polysaccharide isolated from the cell envelop of bovine mastitis Streptococcus dysgalactiae 2023 is reported for the first time. The synthesis was accomplished utilizing a stereoselective and convergent [2 + 2] glycosylation strategy inclusive of a disaccharide Sc...

Bovine mastitis is a disease that concerns animals' welfare and increases the economic production losses. Bacterial agents such as Staphylococcus species are main causative agent of bovine mastitis. This bacterial expresses some inflammatory cytokines might enhance cell-mediated, which may promote pathogenesis The objective current study was to investigate innate immune response circulating lev...

S. aureus is a major aetiological agent of ruminant mastitis worldwide. The chronic nature of S. aureus mastitis makes it difficult to cure and prone to resurgence. In order to identify the bacterial factors involved in this chronicity, Newbould 305 (N305), a strain that can reproducibly induce mild and chronic mastitis in an experimental setting, was characterized in depth. We employed genomic...

The primary objective of this study was to determine the aetiology of bovine mastitis in ten herds of Holstein Friesian cow in Jordan, the prevalence of mastitis pathogens in dairy cows and their resistance to selected antimicrobial agents. Milk samples were collected from 220 lactating cows to determine the clinical and subclinical mastitis by white side test and confirmed by cultural tests. I...

Bovine mastitis causes changes in the milk and serum proteomes. Here both proteomes caused by naturally occurring subclinical clinical have been characterised quantified. Milk samples from healthy dairy cows (n = 10) were compared to those of with 12) using tandem mass tag (TMT) proteomics. Proteins that significantly increased or decreased 237) 117) quantified classified type change mastitis. ...

The study was carried out to investigate the current antibiogram status of bovine mastitis in and around Ranchi. The prevalence of mastitis was assessed by the results of bacteriological evacuation of mastitic milk samples collected from mastitis cases. A total of 150 cases of mastitis were studied for isolation followed by antibiotic sensitivity test. The major prevalent pathogens isolated wer...

We report here the genome sequences of two strains of Escherichia coli (ECA-B and ECC-M) that cause bovine mastitis. These strains are known to be associated with persistent and transient mastitis; strain ECA-B causes a transient infection, and ECC-M leads to a persistent infection.

Mastitis is a major economic concern for the dairy industry. Conditions such as parturition cause a transient immunosuppression that leads to increased incidence of mastitis. One facet of periparturient immunosuppression is a functional impairment of the blood and milk neutrophils in dairy cows. To better understand the biology of the bovine neutrophil we report the first proteomic analysis of ...
