One Health Genomic Analysis of Methicillin‐Resistant Staphylococcus spp. From Humans, Cats, and Dogs in a Veterinary Hospital in Central Chile

Zoonoses and Public Health, EarlyView.
ABSTRACT Introduction The emergence of methicillin‐resistant Staphylococcus species (MRS) poses a growing threat to both human and veterinary health. Methods We performed a comparative genomic characterisation of 49 methicillin‐resistant Staphylococcus isolates collected from humans, dogs, and cats in a veterinary hospital from Central Chile.

Comparative secretome analysis of Staphylococcus aureus strains with different within-herd intramammary infection prevalence

Virulence, 2022
Staphylococcus aureus is a major pathogen causing intramammary infection and mastitis in dairy cows. S. aureus genotypes (GT) can differ significantly in their ability to diffuse and persist in the herd; while the association of virulence gene carriage ...

Diverse immunological roles of liver‐resident immune cells in liver diseases

Precision Medical Sciences, Volume 15, Issue 1, Page 4-17, March 2026.
Based on their origin and functional characteristics, LRICs can be classified into four categories. These cells differ in the focus of their immune functions in liver diseases, yet all exhibit the characteristic of functional bidirectionality.

Staphylococcal leukocidin and .GAMMA.-hemolysin.

Nippon Saikingaku Zasshi, 1997
極めて相同性の高い一次構造を持つ2種類の蛋白質が, 数個のアミノ酸残基の相違により全く異なった機能を持つという事実が Staphylococcus aureus の二成分蛋白毒素ロイコシジンならびにγヘモリジンにおいて明らかにされた。両者は, それぞれヒト白血球および赤血球上で孔を形成する蛋白毒素であるが, ロイコシジンの LukS 成分が, プロテインキナーゼA認識蛋白質であり, 本毒素成分のリン酸化と毒素活性特異性とに強い相関があることが明らかになった。また Panton-Valentine ロイコシジン遺伝子 (lukF-PVおよび lukS-PV) はφPVLと命名された S.

Nanozyme Aptasensor Array for Predictive Sensing of Virulent and Antibiotic‐Resistant Staphylococcus Aureus strains

Small, Volume 22, Issue 15, 12 March 2026.
An array‐based nanozyme‐aptamer platform for rapid, colorimetric fingerprinting of Staphylococcus aureus strains is reported. By combining differential aptamer dissociation with pattern‐recognition analysis, the sensor achieves strain‐level discrimination, infers virulence, and predicts the identification of previously unencountered strains, offering a
