A Hypervirulent Community‐Associated Methicillin‐Resistant Staphylococcus aureus Sequence Type 59 Strain Shows Enhanced Cytotoxicity and Accessory Gene Regulator Activation Compared With Strain USA300

International Journal of Microbiology, Volume 2026, Issue 1, 2026.
Background Different clonal groups of methicillin‐resistant Staphylococcus aureus (MRSA), particularly community‐acquired MRSA (CA‐MRSA), have caused widespread outbreaks and transmission in various regions. Methods We used the North American CA‐MRSA epidemic strain USA300, the Asian CA‐MRSA epidemic strain YNSA7, and ATCC43300 as research subjects ...

Emergence of Livestock‐Associated Methicillin‐Resistant Staphylococcus aureus ST398 in Wild Birds, Brazil

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
In a protected forest fragment in southern Brazil, 197 wild birds were sampled, with 12.2% carrying Staphylococcus aureus. Two MRSA ST398 strains, the first reported in Brazilian wild birds, were identified. Genomic analysis revealed resistance and virulence genes, linking these strains to pigs and underscoring the critical need for resistance ...

The Host R‐M Systems Change the Host Range of Staphylococcus Phage EBHT

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
The study shows how Staphylococcal restriction–modification (R‐M) systems methylate the phage genomic DNA and change the phage host range. The host R‐M systems should be considered when selecting phage manufacturing hosts, as the manufacturing host with a higher yield can result in a narrower phage host range.

Increased Incidence and Plasma-Biofilm Formation Ability of SCCmec Type IV Methicillin-Resistant Staphylococcus aureus (MRSA) Isolated From Patients With Bacteremia

Frontiers in Cellular and Infection Microbiology, 2021
In Japan, Staphylococcal cassette chromosome mec (SCCmec) type IV methicillin-resistant Staphylococcus aureus (MRSA) is an increasingly prominent cause of bacteremia, but the virulence of most of these strains is unclear.

Complete genome sequence of methicillin-sensitive Staphylococcus aureus containing a heterogeneic staphylococcal cassette chromosome element [PDF]

, 2013
Staphylococcus aureus is a common human bacterium that sometimes becomes pathogenic, causing serious infections. A key feature of S. aureus is its ability to acquire resistance to antibiotics.

Antibiotic Resistance: A Genetic and Physiological Perspective

MedComm, Volume 6, Issue 11, November 2025.
The development of resistance to antimicrobials and their historical progression are depicted in this graphic. It draws attention to important biochemical, physiological, and genetic factors that contribute to AMR, such as the transmission of genes, the development of biofilms, and the inactivation of antibiotics.

High frequency of SCCmec type IV and multidrug-resistant SCCmec type I among hospital acquired methicillin-resistant Staphylococcus aureus isolates in Birjand Imam Reza Hospital, Iran

Iranian Journal of Microbiology, 2022
Background and Objectives: The ever-increasing of antibiotic resistance in methicillin-resistant Staphylococcus aureus (MRSA) has become a major threat to public health worldwide. Molecular typing is used to determine the source of MRSA infections as well as to control and prevent the spread of these pathogens.
