Non-aureus Staphylococci Species in the Teat Canal and Milk in Four Commercial Swiss Dairy Herds. [PDF]

Front Vet Sci, 2019
Non-aureus staphylococci (NAS) are frequently found in milk samples as well as on the teat apex and in the teat canal and are known to be a cause of subclinical mastitis. The objective of this study was to investigate the relationship between NAS species colonizing the teat canal and those causing intramammary infection (IMI) in four commercial dairy ...

Fecal non-aureus Staphylococci are a potential cause of bovine intramammary infection [PDF]

Veterinary Research, 2020
The presence of non-aureus staphylococci (NAS) in bovine rectal feces has recently been described. Similar to other mastitis causing pathogens, shedding of NAS in the environment could result in intramammary infection.

Bacteriocins of Non-aureus Staphylococci Isolated from Bovine Milk. [PDF]

Appl Environ Microbiol, 2017
ABSTRACT Non- aureus staphylococci (NAS), the bacteria most commonly isolated from the bovine udder, potentially protect the udder against infection by major mastitis pathogens due to bacteriocin production.

Effects of non- aureus staphylococci on colostrum composition, properties and fatty acid profile in cow – a preliminary study [PDF]

Polish Journal of Veterinary Sciences, 2022
By providing the body with essential nutrients, colostrum plays an immune and immunostimulating function. Colostrum quality depends on multiple factors, including microbial presence. This study aimed to explore the effect of non-aureus staphylococci on colostrum quality.

Known mechanisms cannot account for a third of reduced susceptibility in non-aureus staphylococci. [PDF]

NPJ Antimicrob Resist, 2023
AbstractNon-aureus staphylococci (NAS) are implicated in many healthcare-acquired infections and an understanding of the genetics of antimicrobial resistance is important in relation to both clinical intervention and the role of NAS as a reservoir of resistance genes.

Farming Practice Influences Antimicrobial Resistance Burden of Non-Aureus Staphylococci in Pig Husbandries. [PDF]

Microorganisms, 2022
Non-aureus staphylococci (NAS) are ubiquitous bacteria in livestock-associated environments where they may act as reservoirs of antimicrobial resistance (AMR) genes for pathogens such as Staphylococcus aureus. Here, we tested whether housing conditions in pig farms could influence the overall AMR-NAS burden.

Species identification and cow risks of non-aureus staphylococci from South African dairy herds. [PDF]

Onderstepoort J Vet Res, 2022
Detailed information on specific species of non-aureus staphylococci (NAS) has become a necessity for effective udder health control programs in South Africa. The main objective of this preliminary study was to identify the different NAS species and strains present in dairy herds in South Africa using a cost-effective method. A further objective was to

Peptidomic changes in the milk of water buffaloes (Bubalus bubalis) with intramammary infection by non-aureus staphylococci. [PDF]

Sci Rep, 2022
Abstract Mastitis by non-aureus staphylococci (NAS) is a significant issue in dairy buffalo farming. In a herd with subclinical NAS mastitis, we identified Staphylococcus microti as the predominant species. To assess milk protein integrity and investigate potential disease markers, we characterized 12 NAS-positive and 12 healthy quarter milk ...

Effect of Biosynthesized Gold and Silver Nanoparticles Using Alchemilla vulgaris Extract and Their Synergistic Action with Subinhibitory Concentrations of Ampicillin Against Staphylococci [PDF]

Antibiotics
Background: Staphylococci, recognized for their virulence and antibiotic resistance, are important in both human and veterinary medicine. Loss of sensitivity to beta-lactam antibiotics, such as ampicillin, complicates therapy, prompting the search for ...

Metabolites of bovine-associated non-aureus staphylococci influence expression of Staphylococcus aureus agr-related genes in vitro. [PDF]

Vet Res, 2021
AbstractCommunications via quorum sensing (QS) between non-aureus staphylococci (NAS) and Staphylococcus (S.) aureus in the bovine mammary gland remains largely unexplored. We determined whether 34 S. chromogenes, 11 S. epidermidis, and 14 S. simulans isolates originating from bovine milk samples and teat apices were able to regulate the QS of S ...
