Characterization of Non-tuberculous Mycobacteria by Line Probe Assay Isolated from Pulmonary Tuberculosis Suspected Patients at Rajasthan

Journal of Pure and Applied Microbiology, 2022
Non-tuberculous Mycobacteria (NTM) are emerging as an important opportunistic pathogen. Since clinical presentation of NTM infection is similar to tuberculosis (TB), patients present as suspected TB or drug resistant TB.

Asymptomatic Neurosyphilis Presenting With Bilateral Pulmonary Nodules: A Case Report

Respirology Case Reports, Volume 13, Issue 9, September 2025.
This report presents for the first time, a case of asymptomatic neurosyphilis with multiple pulmonary nodules and buttock lipodystrophy. This case showed a high expression of RPR (154 R.U.) and given the nature of the patient's work (long‐distance transportation), short‐term follow‐up was difficult.

A signal transduction blind spot: the function of adenylyl cyclase transmembrane domains

The FEBS Journal, Volume 292, Issue 17, Page 4477-4486, September 2025.
Transmembrane adenylyl cyclases (tmACs) are essential for synthesising the universal second messenger cyclic AMP. All tmACs share a common topology that includes a large 12‐helix transmembrane (TM) domain. This domain accounts for ~ 35% of the coding sequence but its function is still an open question.

Heterogeneity among Mycobacterium avium complex species isolated from pulmonary infection in Taiwan

Microbiology Spectrum
Mycobacterium avium complex (MAC) is an emerging pathogen causing nontuberculous pulmonary infections globally. However, clinical treatment guidelines regard MAC as a single entity, recommending a universal anti-mycobacterial combination therapy.

Population Genomics and Inference of Mycobacterium avium Complex Clusters in Cystic Fibrosis Care Centers, United States

Emerging Infectious Diseases, 2021
Mycobacterium avium complex (MAC) species constitute most mycobacteria infections in persons with cystic fibrosis (CF) in the United States, but little is known about their genomic diversity or transmission.

Conserved mycobacterial sRNA B11 regulates lipooligosaccharide synthesis at posttranscriptional level in Mycobacterium marinum

mLife, Volume 4, Issue 4, Page 447-460, August 2025.
Abstract Extractable glycolipids of mycobacteria, such as lipooligosaccharides (LOSs), play crucial roles in responding to environmental stress and modulating the host immune response. Although the biosynthesis of LOS is likely regulated at multiple levels to ensure proper composition of the cell wall, the key regulators remain unknown.

Subacute Mastoiditis Without Verified Nontuberculous Mycobacteria—Still a Clinical Challenge

Laryngoscope Investigative Otolaryngology, Volume 10, Issue 3, June 2025.
SAM represents an indolent form of mastoiditis with potential serious complications. Radiology, histopathological, and microbiological sampling is crucial for diagnosing this infection to optimize treatment and improve outcome. ABSTRACT Objective An indolent form of mastoiditis has gained increased attention lately, challenging clinicians both ...

Evidence for evolution of a new sex chromosome within the haploid‐dominant Marchantiales plant lineage

Journal of Integrative Plant Biology, Volume 67, Issue 6, Page 1533-1550, June 2025.
Genomic evidence suggests that sex chromosomes may not be conserved within liverworts. Re‐evolution of dioicy in the genus Riccia may have occurred with probable de novo establishment of a new sex chromosome from the autosome, and the m‐chromosomes have evolved independently from chromosomes in the Marchantiales.
