Human lice have always been a major public health concern due to their vector capacity for louse-borne infectious diseases, like trench fever, relapsing and epidemic which are caused by Bartonella quintana, Borrelia recurrentis, Rickettsia prowazekii, respectively. Those diseases currently re-emerging in the regions of poor hygiene, social poverty, or wars with life-threatening consequences. These also outbreaks among populations jails refugee camps. In addition, antibodies DNAs those pathogens steadily detected homeless populations. Importantly, more bacterial human lice, some transmitted laboratories.

The dissemination of antibiotic resistance in Escherichia coli poses a significant threat to public health worldwide. This review provides comprehensive update on the diverse mechanisms employed by E. developing antibiotics. We primarily focus pathotypes (e.g., uropathogenic ) and investigate genetic determinants molecular pathways that confer resistance, shedding light both well-characterized recently discovered mechanisms. most prevalent mechanism continues be acquisition genes through horizontal gene transfer, facilitated mobile elements such as plasmids transposons. discuss role extended-spectrum β -lactamases (ESBLs) carbapenemases conferring -lactam antibiotics, which remain vital clinical practice. covers key resistant mechanisms, including: 1) Efflux pumps porin mutations mediate broad spectrum including fluoroquinolones aminoglycosides; 2) adaptive strategies , biofilm formation, persister cell activation stress response systems, withstand pressure; 3) regulatory systems coordinating providing insights into potential targets for therapeutic interventions.

Abstract The aquaculture industry is suffering from significant financial setbacks due to an increasing frequency of disease outbreaks, posing a threat the sector’s sustainability. Various bacterial, viral, parasitic, and fungal pathogens have led massive mortalities in farmed fish worldwide. Throughout years, management diseases has predominantly centered around utilization conventional antibiotics chemicals. Nevertheless, their indiscriminate use given rise serious implications, including increase resistant pathogens, disruptions metabolic processes fish, degradation aquatic environment, presence drug residues products, potential human health. effective bio-based immunoprophylaxis alternative therapies been developed overcome these impediments.

Carbapenem-resistant Acinetobacter baumannii (CRAB), particularly the globally prevalent ST2 clone, poses significant threats in Gulf Cooperation Council region through extensive drug resistance, high virulence, and efficient gene transfer. This study investigates epidemiological genomic characteristics of CRAB Jazan region, using whole genome sequencing to understand its transmission genetic determinants. Sixty-five clinical A. isolates exhibiting phenotypic resistance carbapenems (meropenem, imipenem, ertapenem) were collected from various tertiary hospitals region. The presence carbapenemase genes among these was examined two sets multiplex polymerase chain reaction (PCR). Forty-eight confirmed as producers selected for WGS analysis. Among 65 isolates, adult ICU exhibited highest prevalence (76.9%). Multiplex PCR identified 48 (73.8%) producers, all harboring blaOXA-51-like genes. Specifically, blaOXA-23 detected 39 (60%), blaNDM 8 (12.3%), blaOXA-24 one isolate. These carbapenemase-producing also carried virulence-associated related adherence, biofilm formation, immune evasion, iron acquisition regulation, serum resistance. Whole-genome (WGS) revealed that (81.2%) carbapenemase-positive belonged ST2, followed by ST85 ST107, with KL152 locus most common capsule type. indicates a rise clone Arabian Gulf, Saudi Arabia, underscores need ongoing surveillance less clones such ST107 manage public health risks effectively.

Carbapenem-resistant Acinetobacter baumannii (CRAB) is the most detrimental pathogen that causes hospital-acquired infections. Tigecycline (TIG) currently used as a potent antibiotic for treating CRAB infections; however, its overuse substantially induces development of resistant isolates. Some molecular aspects resistance mechanisms AB to TIG have been reported, but they are expected be far more complicated and diverse than what has characterized thus far. In this study, we identified bacterial extracellular vesicles (EVs), which nano-sized lipid-bilayered spherical structures, mediators resistance. Using laboratory-made TIG-resistant (TIG-R AB), demonstrated TIG-R produced EVs control TIG-susceptible (TIG-S AB). Transfer analysis AB-derived treated with proteinase or DNase recipient TIG-S showed EV proteins major factors in transfer. Additional transfer spectrum EV-mediated was selectively transferred Escherichia coli, Salmonella typhimurium, Proteus mirabilis. However, action not observed Klebsiella pneumonia Staphylococcus aureus. Finally, likely induce antibiotics.
