Distribution of non-aureus staphylococci species in udder quarters with low and high somatic cell count, and clinical mastitis [PDF]
Journal of Dairy Science, 2017 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.

Distribution of non-aureus staphylococci from quarter milk, teat apices, and rectal feces of dairy cows, and their virulence potential [PDF]
Journal of Dairy Science, 2020 Non-aureus staphylococci (NAS) are predominantly isolated from bovine milk samples of quarters suffering from subclinical mastitis. They are also abundantly present on dairy cows' teat apices and can be recovered from bovine fecal samples, as recently described.

Antimicrobial resistance in non-aureus staphylococci isolated from milk is associated with systemic but not intramammary administration of antimicrobials in dairy cattle [PDF]
Journal of Dairy Science, 2018 Non-aureus staphylococci (NAS) are the bacteria most frequently isolated from bovine milk. Objectives of this study were to determine herd-level associations between antimicrobial use (AMU) and prevalence of antimicrobial resistance (AMR) and antimicrobial resistance genes in NAS according to antimicrobials and routes of administration. The AMR profile

Typeability of MALDI-TOF assay for identification of non-aureus staphylococci associated with bovine intramammary infections and teat apex colonization [PDF]
Journal of Dairy Science, 2018 Matrix-assisted laser desorption/ionization time of flight (MALDI-TOF), a culture-dependent assay, has recently been implemented for routine identification of non-aureus staphylococci (NAS) species from milk, but the assay has never been investigated for NAS from nonmilk or environmental samples.

Phenotypic and genotypic antimicrobial susceptibility of non-aureus staphylococci in dairy goats
American Association of Bovine Practitioners Conference ProceedingsSubclinical mastitis, most commonly due to non-aureus staphylococci (NAS), results in significant production losses within the dairy goat industry while also shortening the productive life of the animal due to the resultant chronic changes within the udder. The prevalence of this group of pathogens may be up to 50% in some dairies. Dry-off is a common

Veterinary Microbiology, 2022
Linezolid resistance, mediated by the cfr gene, which confers resistant phenotypes to phenicols, lincosamides, oxazolidinones, pleuromutilins, and streptogramin A antimicrobials, has emerged in S. aureus and non-aureus staphylococci (NAS). Moreover, due to the transferable potential via plasmids, the spread of cfr among staphylococci is of great ...

Foodborne Pathogens and Disease
Non-aureus staphylococci (NAS) and mammalicocci (collectively NASM) are coagulase-negative staphylococci, though they are less well-known than Staphylococcus aureus . Certain species within the NASM group have been associated with foodborne illnesses due to their ability to produce ...

Investigating the metabolism of non-aureus staphylococci relevant to prosthetic joint infection [PDF]
, 2020 Prosthetic joint infection (PJI) is a complication of joint replacement that occurs when bacteria adhere to the surface of a prosthetic joint and form a biofilm (Becker et al. 2014; Tande et al. 2014). Treatment is expensive and aggressive, constituting a major burden to the healthcare system and to the patients (Becker et al. 2014; Tande et al. 2014).

Journal of Dairy ScienceNon-aureus staphylococci and mammaliicocci (NASM) are the most frequently isolated bacterial group from bovine milk samples. Most studies focus on subclinical mastitis caused by NASM; however, NASM can cause clinical mastitis (CM) as well. We evaluated retrospective data from 6 years (2017-2022) to determine the species and frequency of NASM isolated ...
