A bacterium capable of utilizing fenpropathrin as sole carbon source was isolated from activated sludge collected from wastewater treating system of a pesticide manufacturer. This bacterium was identified as Sphingomonas sp. according to its physiological & biochemical analysis and the similarity analysis of its 16S rDNA sequence (GenBank Accession No. DQ177525). This bacterium could degrade 99.8% of 20 mg/L fenpropathrin in 24h. The optimal pH and temperature for the degradation were 7.0 and 30 degrees C, respectively. The degradation speed was related positively to initial inoculum size. The enzyme distribution experiment showed that the degrading-enzyme in the bacterium was endoenzyme.

Mikrobiota układu pokarmowego jest nieodzownym elementem właściwego funkcjonowania organizmu człowieka, bowiem drobnoustroje jelitowe i ich metabolity silnie wpływają na metabolizm gospodarza i funkcje odpornościowe, jak również przyczyniają się do biosyntezy witamin, produkcji hormonów jelitowych, utrzymania integralności bariery jelitowej i ochrony przed patogenami, a także trawienia i wchłaniania składników odżywczych. Coraz częściej podkreśla się istnienie zależności pomiędzy zaburzeniami składu mikrobioty jelit a pojawianiem się chorób metabolicznych, tj. otyłości czy cukrzycy typu 2.

This study sought to compare bacterial abundance and diversity in milk and feces of healthy lactating women with patients suffering from lactation mastitis, explore the pathogenesis of lactation mastitis, and develop new ideas for its treatment and prevention from a microbiological perspective. A total of 19 lactating mastitis patients and 19 healthy lactating women were recruited. Milk and fecal Specimens were obtained from both groups, and microbial community structure was analyzed using 16S rRNA gene sequencing.

Objectives Of The Study: The aim of this study was to assess the impact of the COVID-19 pandemic on the epidemiology and clinical course of chickenpox in children based on 6 years of self-reported observations.
Material And Methods: The medical records of 350 patients under 18 years of age hospitalised in the Department of Paediatrics, Infectious Diseases, and Hepatology between 1 January 2018 to 31 December 2023 were analysed retrospectively.
Results: During the analysed period, 350 children were hospitalised due to chickenpox, the fewest in the pandemic period, the greatest number in 2023.
Using BW25113 as a host, we isolated a novel lytic phage from the commercial poly-specific therapeutic phage cocktail Sextaphage (Microgen, Russia). We provide genetic and phenotypic characterization of the phage and describe its host range on the ECOR collection of reference strains. The phage, hereafter named Sxt1, is a close relative of classical coliphage T3 and belongs to the genus, yet its internal virion proteins, forming an ejectosome, differ from those of T3.

Anti-phage defense systems are widespread in bacteria due to the latter continuous adaptation to infection by bacteriophages (phages). has a high degree of intrinsic antibiotic resistance, which makes phage therapy relevant for the treatment of infections caused by this species. Studying the array of anti-phage defense systems that could be found in helps in better adapting the phages to the systems present in the pathogenic bacteria.
