Impact of IL-32 Gene Polymorphisms on Tuberculosis Susceptibility in a Chinese Han population.

Objective: Interleukin (IL)-32, encoded by the IL-32 gene, is a crucial constituent of the autophagy pathway and is involved in the regulation of Mycobacterium tuberculosis (M.tb) infection, a major global health challenge. This study aimed to examine the potential association between IL-32 polymorphisms and susceptibility to Tuberculosis(TB), highlighting the significance of genetic factors in TB risk.

Using Vitek MS v3.0 To Identify Nontuberculous Mycobacteria in Liquid Media in a Clinical Microbiology Laboratory.

Recently, the incidence of diseases caused by nontuberculous mycobacteria (NTM) has been increasing worldwide, especially in immunocompromised patients and those with potential chronic lung disease. Vitek MS v3.0 matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) has emerged as a rapid and reliable method for identifying mycobacteria in clinical laboratories.

Polymorphism in the EREG gene confers susceptibility to tuberculosis.

Background: Host genetic factors affect the immune response to Mycobacterium tuberculosis (Mtb) infection as well as the progression of the disease. Epiregulin (EREG) belongs to the epidermal growth factor (EGF) family, which binds to the epidermal growth factor receptor (EGFR) to regulate the immune response of the host during infections. Our study aimed to compare EREG levels in tuberculosis (TB) patients and healthy controls and assess whether polymorphisms in EREG increase the risk of TB.

Evaluation of the VITEK MS knowledge base version 3.0 for the identification of clinically relevant Mycobacterium species.

Different Mycobacterium spp. infections may indicate varied treatment regimens in the clinic. Thus, the species-level identification of Mycobacterium spp.

Association of Single-Nucleotide Polymorphism in the Hepcidin Promoter Gene with Susceptibility to Extrapulmonary Tuberculosis.

Background: Hepcidin is a 25-amino acid peptide produced by the liver in response to inflammation and iron overload. It is encoded by the hepcidin antimicrobial peptide (HAMP) gene and plays a key role in innate immunity. Previous studies have reported that a -582 A>G polymorphism in the HAMP promoter (HAMP-P) affects hepcidin expression, causing susceptibility to various bacterial and viral pathogens.

Polymorphisms in the prostaglandin receptor EP2 gene confers susceptibility to tuberculosis.

Objectives: Prostaglandin E2 (PGE2) is an important lipid mediator of the inflammatory immune response during acute and chronic infections. PGE2 modulates a variety of immune functions via four receptors (EP1-EP4), which mediate distinct PGE2 effects. Mice lacking EP2 are more susceptible to infection by Mycobacterium tuberculosis (M.

Efflux pump overexpression in conjunction with alternation of outer membrane protein may induce Acinetobacter baumannii resistant to imipenem.

Background: To investigate the role of outer membrane proteins in Acinetobacter baumannii resistant to imipenem, 2 strains were procured from the same patient.

Methods: The imipenem-resistant strain was obtained following a period of imipenem treatment in vivo. The multilocus sequence typing and repetitive extragenic palindromic PCR results indicated that the imipenem-resistant strain originated from the sensitive one.
