Oral and Fecal Microbial Dysbiosis as Non‐Invasive Diagnostic Biomarkers for Gastrointestinal Cancers: A Systematic Review and Meta‐Analysis of Diagnostic Accuracy

open access: yesInternational Journal of Cancer, EarlyView.
ABSTRACT Gastrointestinal (GI) cancers, including esophageal (EC), gastric (GC), and colorectal cancer (CRC), impose a substantial global burden, with early detection remaining crucial for improving patient outcomes. The oral and gut microbiota are increasingly implicated in cancer development and hold promise as sources of non‐invasive biomarkers ...

Comparative Diagnostic Performance of Three Commercial Real‐Time PCR Assays for the Detection of Mycobacterium tuberculosis Complex in Bronchial Washing Specimens: A Large Retrospective Study

open access: yesJournal of Clinical Laboratory Analysis, EarlyView.
This large retrospective study compared the diagnostic performance of three commercial real‐time PCR assays (AdvanSure TB/NTM, Cobas MTB, and Xpert MTB/RIF) for MTBC detection in 3348 bronchial washing specimens. In a head‐to‐head comparison of 740 specimens, the Cobas MTB and Xpert MTB/RIF assays showed markedly higher sensitivity than the AdvanSure ...

Genetic relatedness within the genus Campylobacter inferred from rpoB sequences

open access: yes, 2006
The genus Campylobacter comprises 17 species, some of which are important animal and human pathogens. To gain more insight into the genetic relatedness of this genus and to improve the molecular tools available for diagnosis, a universal sequencing ...

rpoB sequence-based identification of Mycobacterium avium complex species [PDF]

open access: yesMicrobiology, 2008
The Mycobacterium avium complex (MAC) comprises slowly growing mycobacteria responsible for opportunistic infections and zoonoses. The ability to speciate MAC isolates in the clinical microbiology laboratory is critical for determining the organism implicated in clinical disease and for epidemiological investigation of the source of infection ...

Geographical distribution of Brucella melitensis inferred from rpoB gene variation

open access: yesJournal of Infection in Developing Countries, 2017
Introduction: Currently available tests have limitations for the identification of Brucella species and strains, and their genetic lineage. The genome sequence of the rpoB gene encoding the β-subunit of DNA-dependent RNA polymerase was investigated for ...

Phylogenetic analysis of Mycobacterium massiliense strains having recombinant rpoB gene laterally transferred from Mycobacterium abscessus. [PDF]

open access: yesPLoS ONE, 2017
Recent multi locus sequence typing (MLST) and genome based studies indicate that lateral gene transfer (LGT) events in the rpoB gene are prevalent between Mycobacterium abscessus complex strains. To check the prevalence of the M.

Isolation and Identification of Erysipelothrix sp. in Hybrid Grouper (Epinephelus fuscoguttatus × E. lanceolatus) in Taiwan

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT In February 2025, a mortality event of unknown aetiology occurred at a hybrid grouper (Epinephelus fuscoguttatus × Epinephelus lanceolatus) aquaculture farm in southern Taiwan, with sporadic daily deaths persisting for a month. Four moribund groupers were collected over three sampling intervals for diagnostic investigation.

Mutations inside rifampicin-resistance determining region of rpoB gene associated with rifampicin-resistance in Mycobacterium tuberculosis

open access: yesJournal of Infection and Public Health, 2018
Background: Rifampicin (RIF) plays a pivotal role in the treatment of tuberculosis due to its bactericidal effects. Because the action of RIF is on rpoB gene encoding RNA polymerase β subunit, 95% of RIF resistant mutations are present in rpoB gene.

High prevalence of a host‐associated Anaplasma lineage in wild coatis (Nasua nasua) from the Brazilian Atlantic Forest

open access: yesMedical and Veterinary Entomology, EarlyView.
Anaplasma sp. DNA was detected in 47.9% of free‐ranging coatis (Nasua nasua) sampled in Iguaçu National Park, southern Brazil. Molecular analyses revealed a genetically distinct Anaplasma lineage infecting coatis, differing from Anaplasma strains detected in associated tick populations.

Genetic relationships of Aeromonas strains inferred from 16S rRNA, gyrB and rpoB gene sequences [PDF]

open access: yes, 2006
Genetic relationships among bacterial strains belonging to the genus Aeromonas were inferred from 16S rRNA, gyrB and rpoB gene sequences. Twenty-eight type or collection strains of the recognized species or subspecies and 33 Aeromonas strains isolated ...
