Non-aureus staphylococci in fecal samples of dairy cows: First report and phenotypic and genotypic characterization [PDF]

Journal of Dairy Science, 2019
The aims of this study were to determine whether non-aureus staphylococci (NAS) are present in rectal feces of healthy dairy cows, and if so, to delineate species to which they belong and to study several phenotypic and genotypic traits as a first step toward determining the potential impact of fecal shedding of NAS on bovine udder health.

The occurrence of methicillin-resistant non-aureus staphylococci in samples from cows, young stock, and the environment on German dairy farms [PDF]

Journal of Dairy Science, 2021
This study aimed to determine the occurrence of methicillin-resistant (MR) non-aureus staphylococci (NAS) on 20 preselected German dairy farms. Farms were selected based on the detection of methicillin-resistant Staphylococcus aureus (MRSA) during previous diagnostic investigations.

Nasal carriage of antibiotic-resistant staphylococci among undergraduate medical students, with special reference to methicillin-resistant Staphylococcus aureus

Journal of Clinical and Scientific Research, 2021
Background: Staphylococcus aureus and other staphylococci are the commensals of the human body, the anterior nares being an important niche for colonisation. The medical students constitute an important component of the hospital population.

The occurrence of <i>Aerococcus urinaeequi</i> and non-aureus staphylococci in raw milk negatively correlates with <i>Escherichia coli</i> clinical mastitis. [PDF]

mSystems
ABSTRACT Escherichia coli is a common environmental pathogen associated with clinical mastitis (CM) in dairy cattle. There is an interest in optimizing the udder microbiome to increase the resistance of dairy cattle to E.

Cross-Talk between Staphylococcus aureus and Other Staphylococcal Species via the agr Quorum Sensing System

Frontiers in Microbiology, 2016
Staphylococci are associated with both humans and animals. While most are non-pathogenic colonizers, Staphylococcus aureus is an opportunistic pathogen capable of causing severe infections. S.

Prevalence of non-aureus staphylococci species causing intramammary infections in Canadian dairy herds [PDF]

Journal of Dairy Science, 2017
Non-aureus staphylococci (NAS), the microorganisms most frequently isolated from bovine milk worldwide, are a heterogeneous group of numerous species. To establish their importance as a group, the distribution of individual species needs to be determined.

The untargeted lipidomic profile of quarter milk from dairy cows with subclinical intramammary infection by non-aureus staphylococci

Journal of Dairy Science, 2021
This observational study determined the lipidome of cow milk during subclinical intramammary infection (IMI) by non-aureus staphylococci (NAS), also defined as coagulase-negative staphylococci, using an untargeted approach. Among the pathogens causing bovine IMI, NAS have become the most frequently isolated bacteria from milk samples.

Comparative genome analysis of 24 bovine-associated Staphylococcus isolates with special focus on the putative virulence genes [PDF]

PeerJ, 2018
Non-aureus staphylococci (NAS) are most commonly isolated from subclinical mastitis. Different NAS species may, however, have diverse effects on the inflammatory response in the udder. We determined the genome sequences of 20 staphylococcal isolates from
