Vaccine Targets and Antimicrobial Resistance of Streptococcus agalactiae Recovered From Pregnant Women in Brazil

Tropical Medicine &International Health, EarlyView.
ABSTRACT Objectives The available measure to prevent Streptococcus agalactiae (Group B Streptococcus, GBS) neonatal infection is intrapartum antibiotic prophylaxis (IAP), but it is threatened by bacterial resistance. Therefore, this study aimed to investigate antimicrobial resistance and bacterial targets of vaccines at the most advanced stage of ...

Distribution of Flavobacterium psychrophilum and its gyrA genotypes in a river [PDF]

Fisheries Science, 2019
Abstract Flavobacterium psychrophilum can be divided into three genotypes, G-C type (ayu type), A-C type (multi-fish type), and A-T type (salmon-trout type), by two single-nucleotide polymorphisms in the DNA gyrase subunit A (gyrA) gene. We isolated F.

Patterns of Drug Resistance, Drug Resistance Conferring Mutations and Genomic DNA Methylation Revealed in Mycobacterium tuberculosis From South Africa

Tropical Medicine &International Health, EarlyView.
ABSTRACT Tuberculosis remains a major public health threat globally, with drug‐resistant strains undermining treatment efficacy. We analyzed 126 Mycobacterium tuberculosis (M. tuberculosis) isolates with diverse drug resistance spectra and selected 35 for whole genome sequencing (WGS) using Illumina NextSeq, SMRT PacBio Onso and SMRT PacBio Revio ...

Biofilm‐Mediated Persistence of Salmonella in Poultry Processing: A Comprehensive Review of Isolate Heterogeneity, Stress Adaptation, and Antimicrobial Resistance

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 6, November 2026.
ABSTRACT Salmonella enterica remains a major foodborne pathogen in poultry‐processing environments, where its persistence is largely attributed to biofilm formation on food‐contact and non‐food‐contact surfaces. Despite extensive research on Salmonella control, persistent contamination continues to challenge food safety due to the complex interplay ...
