Candida albicans is considered as the leading species causing vulvovaginal candidiasis. Numerous virulence determinants and escalating resistance to antifungal therapy have contributed to its pathogenicity. However, correlation between resistance profiles and virulence patterns of C. albicans is not very well-investigated, which was the main focus of the current study. C. albicans isolates (n = 65) were recovered from vaginal swab specimens and identified to the species level. Antifungal susceptibilities of isolates were performed against (amphotericin B, nystatin, clotrimazole, fluconazole, voriconazole, and micafungin), and their minimum inhibitory concentrations (MICs) were determined according to Clinical and Laboratory Standards Institute (CLSI) guidelines. Virulence patterns including secreted hydrolases (phospholipase, aspartyl protease, and haemolysin), cell surface hydrophobicity, and biofilm production were evaluated. Associations between resistance profiles and virulence patterns of tested C. albicans isolates were analyzed. Isolates showed variable levels of resistance and virulence patterns. Furthermore, there are significant (p < 0.05) positive correlations between amphotericin B MICs and biofilm production. However, significant (p < 0.05) negative correlations are found between fluconazole and voriconazole MICs and cell surface hydrophobicity as well as biofilm production. Moreover, significant (p < 0.05) negative correlations are detected between voriconazole MICs and aspartyl protease production. This study revealed significant correlations between resistance profiles and virulence patterns of C. albicans isolates recovered from vulvovaginal specimens.

Glycogen storage disease type IV (GSD IV) is a rare disease caused by a defect in glycogen branching enzyme 1 (GBE1), which played a crucial role in glycogen branching. GSD IV occurs once in approximately 1 in every 760,000 to 960,000 live births and is inherited in an autosomal recessive pattern. Early diagnosis of GSD IV is challenging due to non-specific symptoms, such as liver and spleen enlargement, which can overlap with other hematologic and hepatobiliary disorders.

Signal transducer and activator of transcription 1 (STAT1) gene mutations have broad clinical phenotypes, classified by the inheritance pattern and functional state. Individuals with autosomal dominant STAT1 deficiency are more susceptible to intracellular bacteria, the hallmark of which is Mendelian susceptibility to mycobacterial diseases (MSMDs) that are associated with increased risks of invasive disease by weakly virulent mycobacteria. We report a novel heterozygous missense mutation in exon 23 of the STAT1 gene (NM_007315.

Unlabelled: Mycobacteria, including pathogens like , exhibit unique growth patterns and cell envelope structures that challenge our understanding of bacterial physiology. This study sheds light on FhaA, a conserved protein in , revealing its pivotal role in coordinating cell envelope biogenesis and asymmetric growth. The elucidation of the FhaA interactome in living mycobacterial cells reveals its participation in the protein network orchestrating cell envelope biogenesis and cell elongation/division.

Introduction: Hypervirulent carbapenem-resistant Klebsiella pneumoniae (hv-CRKP) poses an increasing public health risk due to its high treatment difficulty and associated mortality, especially in bone marrow transplant (BMT) patients. The emergence of strains with multiple resistance mechanisms further complicates the management of these infections.
Methods: We isolated and characterized a novel ST11-KL64 hv-CRKP strain from a pediatric bone marrow transplantation patient.
