Mastitis is a significant disease of adult dairy cattle affecting up to 40 percent of cows within a herd at any given time. Recent surveys show that udder health problems are consistently the most frequent cause of morbidity with the US dairy cattle population (Table 1). The U.S. dairy industry loses an estimated $2 billion every year due to mastitis, with reduced milk production accounting for...

UNLABELLED Although Staphylococcus aureus is best known for infecting humans, bovine-specific strains are a major cause of mastitis in dairy cattle. The bicomponent leukocidin LukMF', exclusively harbored by S. aureus of ruminant origin, is a virulence factor associated with bovine infections. In this study, the molecular basis of the host specificity of LukMF' is elucidated by identification o...

Upon undergoing biomonitoring, the most active dichloromethane extract retrieved from Senna macranthera roots led to the isolation of three main compounds: emodine, physione, and chrysophanol. In this sequence, these compounds revealed a potential antibacterial activity against Staphylococcus aureus strains isolated from animals with mastitis infections with minimum inhibitory concentration (MI...

ABSTRACT Bovine clinical mastitis caused by Staphylococcus spp. is a serious and widespread disease in the world of dairy farming. Antimicrobial therapy fundamental importance prevention treatment infectious mastitis, but indiscriminate use antimicrobials acts as determining factor for spread disease. The present study evaluated resistance profiles 57 isolated from bovine to beta-lactams gentam...

Bovine mastitis is an important disease in the dairy industry responsi?ble for welfare and significant economic losses cows. The treatment of choice administration antibiotics. However, this therapeutic has some disadvantages including presence antibiotics residues milk, low cure rate as well rapid increase antibiotic-resistant pathogens. Therefore, new alternative approaches to were investigat...

Mycoplasma bovigenitalium, a mycoplasmal species involved in various bovine diseases, including genital disease and mastitis, is also a commensal microorganism that inhabits the bovine genital organs. We present here the complete 853,553-bp genome sequence of M. bovigenitalium strain HAZ 596, which was isolated from a bovine vagina in Japan.

The fibronectin-binding proteins (FnBPs) of Staphylococcus aureus are believed to be implicated in the pathogen's adherence to and colonization of bovine mammary glands, thus leading to infectious mastitis. In vitro studies have shown that FnBPs help the adhesion of the pathogen to bovine mammary epithelial cells. However, the importance of FnBPs for the infection of mammary glands has never be...
