Evolution of to degrade halogenated aromatic compounds involves changes in pathway regulation and enzyme specificity.

Halogenated aromatic compounds are used in a variety of industrial applications but can be harmful to humans and animals when released into the environment. Microorganisms that degrade halogenated aromatic compounds anaerobically have been isolated but the evolutionary path that they may have taken to acquire this ability is not well understood. A strain of the purple nonsulfur bacterium, , RCB100, can use 3-chlorobenzoate (3-CBA) as a carbon source whereas a closely related strain, CGA009, cannot.

Bacterial communities associated with wood rot fungi that use distinct decomposition mechanisms.

Wood decomposer fungi are grouped by how they extract sugars from lignocellulose. Brown rot fungi selectively degrade cellulose and hemicellulose, leaving lignin intact, and white rot fungi degrade all components. Many trees are susceptible to both rot types, giving carbon in Earth's woody biomass, specifically lignin, a flexible fate that is affected not only by the fungal decomposition mechanism but also the associated microbial community.

Bacterial Spectrum and Antimicrobial Profile of Pediatric Blood Stream Infection at a Tertiary Care Hospital in Pakistan.

Objectives Blood stream infections (BSIs) are the main cause of morbidity and mortality in children worldwide. The present study was carried out to determine the prevalence of BSI with a focus on the identification of the causative agent of BSI, and to further evaluate the antibiotic susceptibility profile of the causing bacterial pathogens.Methods A cross-section study was carried out at the tertiary care hospital in Peshawar, Pakistan from January to December, 2018.

The Response of Strains to Two Soil Fungi and the Potential Role of Oxalate.

Fungal-associated strains in soil have been extensively studied, but their sensing strategies to locate fungi in soil have remained largely elusive. In this study, we investigated the behavior of five mycosphere-isolated strains [including the type-3 secretion system negative mutant BS001-Δ and the type strain DSM 17804] with respect to their fungal-sensing strategies. The putative role of oxalic acid as a signaling molecule in the chemotaxis toward soil fungi, as well as a potential carbon source, was assessed.

Draft genome sequences of three fungal-interactive strains, BS007, BS110 and BS437.

Here, we report the draft genome sequences of three fungal-interactive 10.1601/nm.27008 strains, denoted BS110, BS007 and BS437.

Transcriptional Responses of the Bacterium Burkholderia terrae BS001 to the Fungal Host Lyophyllum sp. Strain Karsten under Soil-Mimicking Conditions.

In this study, the mycosphere isolate Burkholderia terrae BS001 was confronted with the soil fungus Lyophyllum sp. strain Karsten on soil extract agar plates in order to examine its transcriptional responses over time. At the initial stages of the experiment (T1-day 3; T2-day 5), contact between both partner organisms was absent, whereas in the final stage (T3-day 8), the two populations made intimate physical contact.

Chemotaxis and adherence to fungal surfaces are key components of the behavioral response of Burkholderia terrae BS001 to two selected soil fungi.

Burkholderia terrae BS001 has previously been proposed to be a 'generalist' associate of soil fungi, but its strategies of interaction have been largely ignored. Here, we studied the chemotactic behavior of B. terrae BS001 towards Lyophyllum sp.

The interactions of bacteria with fungi in soil: emerging concepts.

In this chapter, we review the existing literature on bacterial-fungal interactions in soil, exploring the role fungi may play for soil bacteria as providers of hospitable niches. A focus is placed on the mycosphere, i.e.

The genome of the fungal-interactive soil bacterium Burkholderia terrae BS001-a plethora of outstanding interactive capabilities unveiled.

Burkholderia terrae strain BS001, obtained as an inhabitant of the mycosphere of Laccaria proxima (a close relative of Lyophyllum sp. strain Karsten), actively interacts with Lyophyllum sp. strain Karsten.

Characterization of a virulent bacteriophage LK1 specific for Citrobacter freundii isolated from sewage water.

Citrobacter freundii is a worldwide emerging nosocomial pathogen with escalating incidence of multidrug resistance. Citrobacter freundii exists in natural environment, especially in health care settings and is difficult to eradicate. Phage therapy is considered as an alternative way of controlling bacterial infections and contaminations.

Bacteriophages and their implications on future biotechnology: a review.

Recently it has been recognized that bacteriophages, the natural predators of bacteria can be used efficiently in modern biotechnology. They have been proposed as alternatives to antibiotics for many antibiotic resistant bacterial strains. Phages can be used as biocontrol agents in agriculture and petroleum industry.

Coeliac disease in children presenting with failure to thrive.

Background: Coeliac disease used to be considered as a disease of European and Western population but now it has emerged as a global problem. Objective of this study was to evaluate the frequency and mode of presentation of coeliac disease in children presenting with failure to thrive.

Methods: This cross-sectional descriptive study was conducted at Paediatrics Department of Madina Teaching Hospital in collaboration with Histopathology Department of University Medical and Dental College, Faisalabad over a period from April 2010 to March 2011.

Isolation and partial characterization of a virulent bacteriophage IHQ1 specific for Aeromonas punctata from stream water.

Aeromonas punctata is the causative agent of septicemia, diarrhea, wound infections, meningitis, peritonitis, and infections of the joints, bones and eyes. Bacteriophages are often considered alternative agents for controlling bacterial infection and contamination. In this study, we described the isolation and preliminary characterization of bacteriophage IHQ1 (family Myoviridae) active against the Gram-negative bacterial strain A.
