Abstract

Staphylococcus chromogenes is one of the main coagulase-negative staphylococci isolated from mastitis of dairy cows. We describe S. chromogenes isolates that can clot plasma. Since the main pathogen causing mastitis is coagulase-positive Staphylococcus aureus, the coagulase-positive phenotype of S. ...

Abstract

Epidemiological studies have identified Staphylococcus aureus as the most common agent involved in food poisoning. However, current research highlights the importance of toxigenic coagulase-negative staphylococci (CoNS) isolated from food. The aim of this study was to characterize Staphylococcus...

Abstract

The use of antimicrobial agents has led to the emergence of resistant bacterial strains over a relatively short period. Furthermore, Staphylococcus spp. can produce β-lactamase, which explains the survival of these strains in a focus of infection despite the use of a β-lactam antibiotic. The aim of ...

AbstractFull Text

The aim of this study was to identify the main factors affecting the somatic cell count (SCC) in dairy cows under Brazilian conditions. 2657 cows were examined at least once during a 13-month period (June 2002 to July 2003). A total of 3987 milk samples were examined for SCC and mastitis pathogen...

Abstract

Bacteriocins have been suggested as an alternative to conventional antibiotics for the prevention and treatment of mastitis infections. Predominant bacteria associated with bovine mastitis (n=276 isolates) were evaluated for their susceptibility to bovicin HC5, a ruminal bacteriocin produced by ...

Abstract

Staphylococcus aureus is a well-armed pathogen that is a leading cause of bovine mastitis. Attempts to define a set of bacterial proteins that are crucial for infection have failed. The identification of these proteins is important to define biomarkers that can be used for diagnostic purposes and...

Abstract

Bacteria of the genus Staphylococcus are one of the major pathogens causing bovine mastitis. In recent decades, resistance of this genus to oxacillin (methicillin) has been a matter of concern due to the possibility of reducing the effectiveness of mastitis treatments and the transfer of resistance ...

Abstract

Bovine mastitis is an important disease in dairy cattle due to its high incidence and economic losses associated mainly with reduced milk production and treatment costs. The use of antimicrobials to treat clinical cases and at dry off raises the concern of selection of resistant bacterial strains....

AbstractFull Text

Mastitis is an inflammation of the mammary gland that affects dairy cattle worldwide causing economic losses. Coagulase-negative staphylococci (CNS) are the predominant cause of this type of infection. We have recently showed that coagulase-positive staphylococci could be misidentified. So, the aim ...
