Bordetella BcrH1 and BcrH2 Are Specific Chaperones for the Pore‐Forming Complex

Microbiology and Immunology, Volume 70, Issue 2, Page 57-67, February 2026.
ABSTRACT Bordetella has a type III secretion system that secretes virulence proteins crucial to the establishment of infection. The genes encoding components of the Bordetella type III secretion system are located in the bsc region on the chromosome. This region includes the bcrH1 and bcrH2 genes, which respectively encode the proteins BcrH1 and BcrH2.

Rifampin and rpoB mutations can alter DNA supercoiling in Escherichia coli [PDF]

Journal of Bacteriology, 1988
Two cases are described which indicate that RNA polymerase could alter DNA supercoiling. One occurred in a topA mutant in which abnormally high levels of plasmid supercoiling were lowered by rifampin, an inhibitor of the beta subunit of RNA polymerase. The second case involves suppression of a temperature-sensitive gyrB mutation by a rifampin-resistant

DNA repair systems and the pathogenesis of Mycobacterium tuberculosis: varying activities at different stages of infection [PDF]

, 2010
Mycobacteria, including most of all MTB (Mycobacterium tuberculosis), cause pathogenic infections in humans and, during the infectious process, are exposed to a range of environmental insults, including the host's immune response.

Detection and Genetic Diversity of Heritable Bacterial Symbionts in Human Lice Based on 16S‐rRNA Gene

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Candidatus Riesia pediculicola and Wolbachia were found in 79.6% and 95.2% of head lice, and 81.8% and 100% of body lice. Candidatus Riesia pthiripubis and Wolbachia appeared in 41.7% and 75% of pubic lice. Maximum‐likelihood 16S‐rRNA phylogeny revealed substantial heterogeneity within symbiont populations. ABSTRACT Human lice are obligate bloodsucking

rpoB Gene Sequencing for Identification of Rapidly Growing Mycobacteria

Archives of Pediatric Infectious Diseases, 2016
Background: Rapidly growing mycobacteria (RGM) are increasingly recognized as a cause of human infections. Rapid and reliable identification of RGM at species level should be carried out as a means of effective patient managements. Methods: Twenty clinical samples of RGM isolated from suspected tuberculosis (TB) patients were included.

Genetic diversity of Legionella pneumophila inferred from rpoB and dotA sequences [PDF]

Clinical Microbiology and Infection, 2006
This study characterised the population structure of Legionella pneumophila by comparing the rpoB (300-bp) and dotA (360-bp) sequences of 267 isolates (18 reference strains, 149 Korean isolates and 100 Japanese isolates). In addition to the six clonal subgroups established previously, four subgroups, P-V to P-VIII, were identified.

The consequences of replicating in the wrong orientation: Bacterial chromosome duplication without an active replication origin [PDF]

, 2015
Chromosome replication is regulated in all organisms at the assembly stage of the replication machinery at specific origins. In Escherichia coli the DnaA initiator protein regulates the assembly of replication forks at oriC.

Isolation, identification, and pathogenic potential of Bacillus cereus from diseased big‐belly seahorse Hippocampus abdominalis

Journal of the World Aquaculture Society, Volume 57, Issue 1, February 2026.
Abstract Members of Bacillus cereus have been documented as important bacterial pathogens in aquaculture. However, scarce information is available on B. cereus isolates as causal pathogens of big‐belly seahorses Hippocampus abdominalis. In the present study, a B. cereus isolate (SH1), recovered from a disease outbreak on a seahorse farm, was identified
