Abstract

The effect of non-aureus staphylococci (NAS) in bovine mammary health is controversial. Overall, NAS intramammary infections (IMI) increase somatic cell count (SCC), with an effect categorized as mild, mostly causing subclinical or mild to moderate clinical mastitis. However, based on recent...

Abstract

Introduction: Staphylococcus aureus and coagulase-negative staphylococci (CNS) are frequently isolated from cows with mastitis. A main virulence factor of CNS is the ability to adhere and form biofilms. The intercellular gene cluster adhesion (ica) operon is one factor involved in biofilm...

Abstract

In many parts of the world, coagulase-negative staphylococci (CNS) are the predominant cause of intramammary infections (IMI) in dairy cows and in water buffaloes, as well. A longitudinal field study was carried out on one well-managed dairy water buffalo herd to determine the prevalence and...

Abstract

Subclinical mastitis caused by intramammary infections (IMI) with coagulase-negative staphylococci (CNS) is common in dairy cows and may cause herd problems. Control of CNS mastitis is complicated by the fact that CNS contain a large number of different species. The aim of the study was to...

Abstract

Coagulase-negative staphylococci (CNS) have emerged as bovine mastitis pathogens in many countries. CNS mastitis is generally mild but can persist in the udder for long periods. Pathogenesis of CNS intramammary infection is not well understood. In the present study, adhesion, invasion and...

AbstractFull Text

Some of the bovine mastitis pathogens were relevant either in respect to the milk quality as well as to public health. The objective of this study was to evaluate the main mastitis pathogens occurrence in Brazilian dairy herds, in order to verify the persistence of classical etiological agents and...

Abstract

The aim of this study was to investigate the prevalence of gram-positive bacteria causing cow mastitis in cows and determine their susceptibility to beta-lactam antibiotics. Eight hundred and seventy one isolated gram-positive bacterial strains belonged to Staphylococcus (n=506), Streptococcus...

Abstract

The aim of this study was to investigate whether the main coagulase-negative staphylococci (CNS) species involved in bovine intramammary infections (IMI) possess specific characteristics that promote colonization of the udder. Virulence markers associated with biofilm formation, antimicrobial...

Abstract

Coagulase-negative staphylococci (CNS) are the most commonly isolated bacteria from goat milk, but they have often been identified with phenotypic methods, which may have resulted in misclassification. The aims of this paper were to assess the amount of misclassification of a phenotypic test for...
