is responsible for Q fever, a zoonosis that mainly manifests as a mild acute infection and may persist in specific individuals causing severe complications, including endocarditis and vascular infections. Transmission mainly occurs through the inhalation of aerosols, underlining bacterial resistance to environmental stress. is an intracellular gram-negative pathogen that can infect and survive in monocytes and macrophages and replicate within acidic compartments. expresses several virulence factors, including lipopolysaccharide and a type IV secretion system, which are involved in hijacking several functions of the immune system and controlling cell death. This review summarizes research on infection from clinical presentation of Q fever to bacterial and host factors of virulence. It compiles immunological data associated with bacterial cure or persistence and discusses a potential link between macrophage interaction and immune dysregulation of Q fever.

Aim: To investigate the phenotypic and genomic features of three multidrug-resistant (MDR) clinical mucoid and non-mucoid uropathogenic Escherichia coli (UPEC) strains to understand their antimicrobial resistance, biofilm formation, and virulence in urinary tract infections (UTIs).
Methods And Results: The UPEC strains A5, A10, and A15 were isolated from two UTI patients. Phenotypic assays included colony morphology, antibiotic susceptibility, motility, and biofilm formation.

Biofilm formation and other virulence phenotypes under quorum sensing regulation play a vital role in the pathogenicity of Aeromonas hydrophila, triggering the emergence of multi-drug resistance (MDR) which increases fish mortality, environmental issues, and economic loss in aquaculture, necessitating the discovery of novel drugs to bypass standard antibiotics. Here, quorum quenching (QQ) may be a sustainable anti-virulent approach. β-Lactamase enzyme obtained from Chromohalobacter sp.

Efficient DNA delivery is essential for genetic manipulation of mycobacteria and for dissecting their physiology, pathogenesis, and drug resistance. Although electroporation enables transformation efficiencies exceeding 10⁵ CFU per µg DNA in and , it remains highly inefficient in many nontuberculous mycobacteria (NTM), including . Here, we discovered that NTM such as exhibit exceptional tolerance to ultra-high electric field strengths and that hypertonic preconditioning partially protects cells from electroporation-induced damage.

Unlabelled: Lactobacilli, recognized as beneficial bacteria within the human body, are celebrated for their multifaceted probiotic functions, including the regulation of intestinal flora, enhancement of body immunity, and promotion of nutrient absorption. This study comprehensively analyzed the genotypic and phenotypic characteristics of () strains isolated from the intestines of healthy chicks and assessed their potential as probiotics. The assembled genome consists of 29,521,986 bp, and a total of 1,771 coding sequences (CDSs) were predicted.
