In this study of the diversity of AmpC β-lactamase in clinical isolates of Enterobacter spp., a strain was found carrying the plasmid-mediated AmpC β-lactamase ACT-1 gene on its chromosome. The strain was identified as Enterobacter hormaechei using phylogenetic analysis of 16S rRNA and hsp60 genes. In addition, the species was confirmed by DNA-DNA hybridization. The genetic environment of the b...

The name Enterobacter hormaechei is proposed for a new species of the family Enterobacteriaceae, formerly called Enteric Group 75, which consists of 23 strains, 22 of which were isolated from humans. DNAs from 12 E. hormaechei strains tested were highly related to the type strain (ATCC 49162) by DNA hybridization, using the hydroxyapatite method (80 to 97% in 60 degrees C reactions; 80 to 90% i...

AIM Enterobacter cloacae complex bacteria are of both clinical and environmental importance. Phenotypic methods are unable to distinguish between some of the species in this complex, which often renders their identification incomplete. The goal of this study was to develop molecular assays to identify Enterobacter hormaechei and Ent. cloacae genetic cluster III which are relatively frequently e...

Abstract Petroleum oil contaminants have become severe ecological problems and negatively impact human health. It is, therefore, imperative to identify environmentally friendly approaches remediate oil-polluted environments. Therefore, bacterial degradation stimulated with a nitrogen source under optimum conditions was assessed in this study. Based on the 16S rRNA analysis, strain ODB H32 recov...

The present work aims to investigate the midgut bacteria of honey bee (Apis mellifera lamarckii) workers and larvae infested with Varroa destructor. To achieve this task, uninfested parasitic mites were obtained from natural bees apiaries in Qaliubiya Governorate, Egypt. Aerobic isolated A. on nutrient agar medium identified using a culture-dependent isolation along 16S rRNA sequences. results ...

The aim of this paper was to determine in 32 patients from 4 different Mexican hospitals the frequency of opportunistic bacteria in the 2010 to 2011 time period. The patients were divided in 4 groups. Group 1 included 21 HIV positive patients with acute respiratory syndrome. Four HIV positive patients with tuberculosis symptoms were included in Group 2; two patients with tuberculosis symptoms a...

This study was aimed to determine the genetic distribution and characteristics of bacterial family in Batang Ai reservoir their possible sources transmission into lake water. Surface water samples were collected from twenty-seven sampling points scattered around four fish obtained an aquaculture farm located within reservoir. The plated on Violet Red Bile Agar (VRBA) plates for isolation Entero...
