International Forum of Allergy &Rhinology, EarlyView.ABSTRACT Background Pseudomonas aeruginosa is an opportunistic pathogen in cystic fibrosis‐related chronic rhinosinusitis (CF‐CRS) that produces phenazine metabolites pyocyanin and 1‐hydroxyphenazine (1‐HP), which may have detrimental effects on mitochondria, reactive oxygen species (ROS), Ca2+ signaling, and apoptosis.

Animal Models and Experimental Medicine, EarlyView.Irrigation of periodontal pockets with human periopathogens, in combination with a 14‐day ligature‐induced periodontitis protocol, significantly enhances alveolar bone loss and sustains bacterial colonization for up to 28 days following ligature removal, thereby more closely replicating the chronic nature of human periodontitis compared to the ligature

Establishment of a biosafe murine model of skeletal tuberculosis using Mycobacterium smegmatis
Animal Models and Experimental Medicine, EarlyView.This study developed a biosafe, accessible, and versatile murine model of bone TB using Mycobacterium smegmatis, a fast‐growing, nonpathogenic mycobacterial species with high genomic homology to Mycobacterium tuberculosis. Three infection routes—subperiosteal calvarial injection, intratibial injection, and intracardiac (left ventricular) inoculation ...

Virulence Factors of Bordetella pertussis.
Nippon Saikingaku Zasshi, 1996 百日咳はワクチン接種の普及により日本では過去の病気となりつつあるが, 予防接種の行き渡らない国々では今なお猛威を奮っている小児の呼吸器伝染病で, 病因的にはジフテリアと同様, 毒素性疾患として理解し得る。最近では伝染源としての成人感染者が問題視され始めたが, 呼吸器感染症の常として根絶は殆ど不可能であり, 感染の予防, 治療に関する研究成果のみが百日咳の制圧を可能にする途である。本小文では, 百日咳菌の産生する病原因子のうち, 感染の第一段階である宿主細胞への菌の吸着に関与する接着因子 (繊維状赤血球凝集素, 線毛, パータクチン) および百日咳症の発現に関与する毒素類 (百日咳毒素, アデニレートシクラーゼ毒素, 気管上皮細胞毒素, 皮膚壊死毒素, 内毒素) の産生, 性状 ...

Surfactant‐Enhanced Electrospun Nanofiber Filters for Efficient Viral and Bacterial Inactivation
Journal of Applied Polymer Science, EarlyView.In this work, electrospun polyacrylonitrile (PAN) nanofibrous filters functionalized with surfactants (CTAB, CPC, and SDS) were developed for air filtration applications. The PAN nanofiber mats enable efficient particulate matter capture while simultaneously providing antimicrobial and antiviral activity against bacteria (E. coli and S.

Animal Research and One Health, EarlyView.Activo Liquid and Halquinol inhibit Salmonella and Escherichia coli in culture media. Activo Liquid exhibits bactericidal action, whereas HA is bacteriostatic, and their combination results in positive or indifferent interactions. This combination effectively inhibits E. coli throughout digestion simulation, thus reducing the required concentrations of
