Quorum Sensing Inhibits Type III‐A CRISPR‐Cas System Activity Through Repressing Positive Regulators SarA and ArcR in Staphylococcus Aureus

Advanced Science, Volume 12, Issue 36, September 25, 2025.
This study proposes a novel model illustrating how quorum sensing (QS) regulates the type III‐A CRISPR‐Cas system in Staphylococcus aureus. The QS regulator AgrA suppresses CRISPR‐Cas activity by downregulating the transcriptional regulators SarA and ArcR.

A new multiplex PCR for easy screening of methicillin-resistant Staphylococcus aureus SCCmec types I–V [PDF]

, 2007
A multiplex PCR with four primer-pairs was designed to identify the five main known SCCmec types. A clear and easily discriminated band pattern was obtained for all five types.

An unexpected location of the arginine catabolic mobile element (ACME) in a USA300-related MRSA strain.

PLoS ONE, 2011
In methicillin resistant Staphylococcus aureus (MRSA), the arginine catabolic mobile element (ACME) was initially described in USA300 (t008-ST8) where it is located downstream of the staphylococcal cassette chromosome mec (SCCmec).

CC8 MRSA Strains Harboring SCCmec Type IVc are Predominant in Colombian Hospitals

PLoS ONE, 2012
Contexte Des rapports récents soulignent l'incursion du SARM associé à la communauté dans les établissements de soins de santé. Cependant, la connaissance de ce phénomène reste limitée en Amérique latine. L'objectif de cette étude était d'évaluer l'épidémiologie moléculaire du SARM dans trois hôpitaux de soins tertiaires à Medellín, en Colombie ...

Genetic diversity of Staphylococcus aureus strains from a teaching hospital in Isfahan, Iran: The emergence of MRSA ST639- SCCmec III and ST343- SCCmec III.

Iranian journal of microbiology, 2018
Staphylococcus aureus is an important pathogen that can be colonized in the nose and increase the risk of spreading infections in hospitals. The present study aimed at determining the phenotypic and genotypic characterization of S. aureus strains isolated from patients and healthcare workers (HCWs) from a teaching hospital in Isfahan, Iran.This cross ...
