The fct cbsCEBA operon from the Erwinia chrysanthemi 3937 chrysobactin-dependent iron assimilation system codes for transport and biosynthetic functions. The sequence of the fct outer membrane receptor gene was determined. The fct promoter region displays a strong resemblance to the Escherichia coli bidirectional intercistronic region controlling the expression of the fepA-entD and fes-entF ope...

A total 63 samples were collected during the rainy season August- October 2018 dry season, equally January- March 2019. Composite method employed Areas coded, labelled, sealed pres...

BACKGROUND This study examines the dual role of Escherichia coli in the course of ulcerative colitis (UC). The intestinal microbiota is considered to play an important role in UC pathogenesis, but how E. coli contributes to inflammation in UC is still unknown. On the one hand, we demonstrated that there was a significant increase in the number of E. coli at the sites of inflammation in patients...

Traffic noise in urban areas has always been a global issue. This study focuses on the land use analysis of traffic levels Jos Metropolis. The was conducted Metropolis, Plateau State, Nigeria. Twenty-five (25) road corridors were sampled for study. Measurement points randomly selected along corridors. collected using Sound Level Meter. sound level meter positioned at distance 6.5 m from centrel...

Acinetobacter baumannii is emerging as a leading global multiple-antibiotic-resistant nosocomial pathogen. The identity of genes essential for pathogenesis in a mammalian host remains largely unknown. Using transposon-directed insertion-site sequencing (TraDIS), we identified A. baumannii genes involved in bacterial survival in a leukopenic mouse model of bloodstream infection. Mice were inocul...
