Fungal rhinosinusitis is on the rise worldwide and it is endemic especially in North India. The main purpose of this study was to determine the antifungal resistance profile of fungal isolates from the cases of fungal rhinosinusitis. Antifungal susceptibility testing of isolated fungi to fluconazole, amphotericin B, itraconazole, and voriconazole was determined by standard CLSI broth microdilution method. Sixty-eight fungal isolates of . ( = 49), ( = 9), . ( = 4), . ( = 2), . ( = 2), . ( = 1), and . ( = 1) were obtained from 60 different clinical samples as exudate from nasal mucosa ( = 28), allergic mucin ( = 8), nasal lavage ( = 2), tissue biopsy from nasal polyps ( = 14), and intraoperative nasal mucosa ( = 8). Of the 68 isolates, 75% were resistant to fluconazole, 13.23% were resistant to itraconazole, 2.94% to amphotericin B, and none were resistant to voriconazole. (5%) was the only fungi found resistant to amphotericin B, while against itraconazole, flavus (7.5%) and (100%) were found resistant. All the isolates of , , , and spp. were resistant to fluconazole. Although amphotericin B stills remains to be the most effective drug, more prospective studies are needed for the requirement of knowledge of the sensitivity pattern for optimal treatment and reduction in morbidity in the long run.

Factors associated with tuberculosis treatment initiation among bacteriologically negative individuals evaluated for tuberculosis: An individual patient data meta-analysis.

Background: Globally, over one-third of pulmonary tuberculosis (TB) disease diagnoses are made based on clinical criteria after a negative bacteriological test result. There is limited information on the factors that determine clinicians' decisions to initiate TB treatment when initial bacteriological test results are negative.
Methods And Findings: We performed a systematic review and individual patient data meta-analysis using studies conducted between January 2010 and December 2022 (PROSPERO: CRD42022287613).
Microbiota-derived proteins synergize with IL-23 to drive IL22 production in model type 3 innate lymphoid cells.

Microbiota-induced production of IL-22 by type 3 innate lymphoid cells (ILC3) plays an important role in maintaining intestinal health. Such IL-22 production is driven, in part, by IL-23 produced by gut myeloid cells that have sensed select microbial-derived mediators. The extent to which ILC3 can directly respond to microbial metabolites via IL-22 production is less clear, in part due to the difficulty of isolating and maintaining sufficient numbers of viable ILC3 ex vivo.

Background: We aimed to determine the household distribution and viability of Chlamydia trachomatis (Ct) from the eyes, face, and hands during the initial two visits of a year-long fortnightly cohort study in geographically defined adjacent households.
Methods/findings: We enrolled 298 individuals from 68 neighbouring households in Shashemene Woreda, Oromia, Ethiopia. All individuals above 2 years of age residing in these households were examined for signs of trachoma.

Two novel yeast strains, NYNU 236247 and NYNU 23523, were isolated from the leaves of Hance, collected in the Tianchi Mountain National Forest Park, Henan Province, central China. Phylogenetic analysis of the D1/D2 domain of the large subunit rRNA gene and the internal transcribed spacer (ITS) region revealed the closest relatives of the strains are three described species: , and . The novel species differed from the type strains of these three species by 12 to 22 nucleotide substitutions and 1 gap (~2.
