New Insight regarding Legionella Non-Pneumophila Species Identification: Comparison between the Traditional mip Gene Classification Scheme and a Newly Proposed Scheme Targeting the rpoB Gene

Microbiology Spectrum, 2021
The identification of Legionella non-pneumophila species (non-Lp) in clinical and environmental samples is based on the mip gene, although several studies suggest its limitations and the need to expand the classification scheme to include other genes. In

New and Improved Diagnostics for Detection of Drug-Resistant Pulmonary Tuberculosis. [PDF]

, 2011
PURPOSE OF REVIEW: Tuberculosis (TB) remains a global emergency and continues to kill 1.7 million people globally each year. Drug-resistant TB is now well established throughout the world and most TB patients are not being screened for drug resistance ...

A Hanks‐type bacterial kinase, PknS, directly phosphorylates the alternative sigma factor EcfK to promote resistance to protist predation

The FEBS Journal, EarlyView.
The Xanthomonas citri Hanks‐type kinase PknS autophosphorylates and directly phosphorylates the alternative sigma factor EcfK at five residues. Besides the conserved residue T51 in the σ2 domain, phosphorylation of a residue in the linker between σ2 and σ4 is critical for EcfK activation by promoting its interaction with a positively charged pocket in ...

Molecular Analysis of Rifampicin Resistance Conferring Mutations in Mycobacterium tuberculosis

مجلة بغداد للعلوم, 2020
Mycobacterium tuberculosis resistance to rifampicin is mainly mediated through mutations in the rpoB gene. The effects of rpoB mutations are relieved by secondary mutations in rpoA or rpoC genes.

Mutations in 1700 Bp Fragment of Rpob Gene of Multi-drug Resistant Mycobacterium Tuberculosis Isolate [PDF]

, 2012
This research aimed to amplify a 1700 bp fragment of rpoB gene of multidrug resistance M. tuberculosis (MDR-TB) isolate and determine types of mutation beyond the core region (hot-spot region).

Tripartite Symbiosis Between Legumes, Arbuscular Mycorrhizal Fungi and Nitrogen Fixing Rhizobia: Interactions and Regulation

Plant, Cell &Environment, EarlyView.
ABSTRACT Legume plants can interact with nitrogen‐fixing rhizobia bacteria and arbuscular mycorrhizal fungi (AMF) simultaneously, forming a tripartite symbiotic association. Co‐inoculation studies performed on a variety of legumes have shown that rhizobia and AMF influence each other when they co‐occur in tripartite association and affect host plant ...

SMC is recruited to oriC by ParB and promotes chromosome segregation in Streptococcus pneumoniae [PDF]

, 2011
Segregation of replicated chromosomes is an essential process in all organisms. How bacteria, such as the oval-shaped human pathogen Streptococcus pneumoniae, efficiently segregate their chromosomes is poorly understood.

The Role of Nontuberculous Mycobacteria in Patients With Cystic Fibrosis Advanced Lung Disease

Transplant Infectious Disease, EarlyView.
Among 270 cystic fibrosis patients, 20.7% were NTM‐positive and had a lower pre‐transplant risk of death or lung transplantation but higher post‐transplant mortality, with no difference in CLAD incidence. These results suggest NTM infection should not be an absolute contraindication to lung transplantation, though careful individual risk assessment is ...

Natural Co‐Infection With Streptococcus agalactiae and Klebsiella pneumoniae in Cultured Nile Tilapia: Assessing Plant‐Based Therapeutics as Sustainable Alternatives to Antibiotics

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Nile tilapia (Oreochromis niloticus), a key species in global freshwater aquaculture and a major contributor to Bangladesh's fish production, is increasingly affected by bacterial infections that compromise farm productivity. This study investigated natural co‐infection of bacterial pathogens in diseased tilapia and assessed the effectiveness ...
