Spatial Patterns and Associated Factors of Intestinal Antibiotic Resistance Genes in Farmed Bullfrogs From Selected Farms Across Major Production Regions in China

Integrative Zoology, EarlyView.
Across selected bullfrog farms in major Chinese production regions, 106 intestinal ARG subtypes were detected, with tetracycline and sulfonamide resistance genes predominating and clear farm‐level variation. High‐risk ARGs, including ermB, floR, and qnrA, were associated with heavy metals, MGEs, and opportunistic pathogens. These findings highlight the

Multiplex real-time PCR for detection of Staphylococcus aureus, mecA and Panton-Valentine Leukocidin (PVL) genes from selective enrichments from animals and retail meat. [PDF]

PLoS ONE, 2014
The aim of this study was to compare a real-time PCR assay, with a conventional culture/PCR method, to detect S. aureus, mecA and Panton-Valentine Leukocidin (PVL) genes in animals and retail meat, using a two-step selective enrichment protocol.

High Endothelial Venules in Small Cell Lung Cancer: Prognostic Subtypes and Therapeutic Implications for Immunoradiotherapy

International Journal of Cancer, Volume 159, Issue 9, Page 2314-2327, 1 November 2026.
ABSTRACT Small cell lung cancer (SCLC) is a highly aggressive neuroendocrine malignancy with an immunosuppressive tumor microenvironment, and current immunotherapy provides limited benefit. This highlights the need to identify microenvironmental features enabling effective immune responses.

Evaluation of the accuracy of various phenotypic tests to detect oxacillin resistance in coagulase-negative staphylococci

Brazilian Journal of Infectious Diseases
In this study, we determined the accuracy of phenotypic tests (cefoxitin agar dilution, 30µg-cefoxitin and 1µg-oxacillin disks) to detect the oxacillin resistance/mecA gene among coagulase-negative staphylococci (CoNS) isolates.

Molecular Diagnostics for WHO Priority Bacterial Pathogens: A Bibliometric Mapping of Diagnostic Platforms, Resistance Markers, and Antimicrobial Resistance Research Trends

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
This bibliometric mapping of 1746 publications (2000–2025) charts molecular diagnostics for WHO priority bacterial pathogens across platforms, targets, and resistance markers. Conventional PCR/NAAT and whole‐genome sequencing emerge as complementary core platforms, and the field evolves from targeted pathogen detection into an AMR‐centered ...

Prevalence of mecA, mecC and Panton-Valentine-Leukocidin Genes in Clinical Isolates of Coagulase Positive Staphylococci from Dermatological Canine Patients

Microorganisms, 2022
Coagulase positive Staphylococci (CoPS) are the leading cause of canine cutaneous and otic infections. Virulence factors associated with Staphylococci include the expression of mec and panton-valentine leukocidin (pvl) genes.

The anti-repressor MecR2 promotes the proteolysis of the mecA repressor and enables optimal expression of β-lactam resistance in MRSA. [PDF]

PLoS Pathogens, 2012
Methicillin-resistant Staphylococcus aureus (MRSA) is an important human pathogen, which is cross-resistant to virtually all β-lactam antibiotics. MRSA strains are defined by the presence of mecA gene.

Nasopharyngeal Carriage Rate, Risk Factors, and Co‐Resistance Patterns of Methicillin‐Resistant Staphylococcus aureus in Ethiopia: Systematic Review and Meta‐Analysis

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
This systematic review and meta‐analysis show that nasopharyngeal carriage of methicillin‐resistant Staphylococcus aureus remains an important public health concern in Ethiopia. High resistance to commonly used antibiotics and significant associations with prior hospitalization and antibiotic use highlight the need for strengthened antimicrobial ...
