Identification and Genomic Analysis of the First Salmonella typhimurium Monophasic Variant 1,4,[5],12:i:‐ Isolate Harbouring a Chromosomally Integrated blaNDM‐5

Microbial Biotechnology, Volume 19, Issue 7, July 2026.
This study reports the first clinical isolate of the monophasic variant of Salmonella typhimurium (serotype 1,4,[5],12:i:‐) ST34 harbouring a chromosomally integrated blaNDM‐5. The ~11 kb resistance region is flanked by two directly oriented IS26 elements, forming an IS26‐composite transposon.

Characteristics of Salmonella enterica Serovar 4,[5],12:i:- as a Monophasic Variant of Serovar Typhimurium

PLoS ONE, 2014
Salmonella enterica subspecies enterica serovar 4,[5],12:i:- (S. 4,[5]12:i:-) is believed to be a monophasic variant of S. enterica serovar Typhimurium (S. Typhimurium). This study was conducted to corroborate this hypothesis and to identify the molecular and phenotypic characteristics of the S. 4,[5]12:i:- isolates in Japan. A total of 51 S. 4,[5]12:i:

Cytosolic delivery of bacterial metabolites by riboflavin transporters promotes MR1 antigen presentation and MAIT cell recognition

Immunology &Cell Biology, Volume 104, Issue 6, Page 595-608, July 2026.
VitBAg antigen presentation is promoted through a cytosolic pathway that reaches ligand‐receptive MR1 to present to MAIT cells, like the riboflavin transport pathway. Riboflavin solute carrier transporters can promote this MR1 presentation, but they are not essential for this role, suggesting redundant pathways to uptake VitBAg.

PLP Homeostasis Protein Is Required for Efficient Maturation of Aromatic Amino Acid Aminotransferase in Salmonella enterica

Molecular Microbiology, Volume 126, Issue 1, Page 1-14, July 2026.
Cellular pool of aromatic amino acid aminotransferase proteins represented as holo‐ or apo‐ enzymes, reflecting presence or absence of associated PLP. Status of PLPHP is implicated in determining the ratio of holo‐ and apo‐TyrB. ABSTRACT Pyridoxal 5′‐phosphate (PLP) is an essential cofactor required for metabolic functions including amino acid ...

Update of the list of qualified presumption of safety (QPS) recommended microbiological agents intentionally added to food or feed as notified to EFSA 24: Suitability of taxonomic units notified to EFSA until March 2026

EFSA Journal, Volume 24, Issue 7, July 2026.
Abstract The Qualified Presumption of Safety (QPS) process was developed to provide a harmonised safety assessment approach to support EFSA Scientific Panels and Units. The QPS approach assesses the taxonomic identity, body of knowledge and safety of microorganisms intentionally added to the food and feed chain.

Chlamydia trachomatis Serovars from the C-Complex and the B- and C-Related Complexes Are Significantly More Pathogenic than Those from the B-Complex in C3H/HeN but Not in BALB/c Mice

Pathogens
Studies in humans indicate that certain Chlamydia trachomatis serovars are more pathogenic than others. Specifically, several studies concluded that serovars from the C-complex are more pathogenic than those from the B-complex, although there are reports
