Catheter associated urinary tract infections by P. aeruginosa are related to variety of complications. Quorum sensing and related circuitry guard its virulence potential. Though P. aeruginosa accounts for an appreciable amount of virulence factors, this organism is highly unstable phenotypically. Thus, genotyping of clinical isolates of P. aeruginosa is of utmost importance for understanding th...

In the human pathogen Pseudomonas aeruginosa, the GltR regulator is required for glucose transport, whereas GtrS is a sensor kinase that plays a key role in mediating bacteria-host interaction and pathogen dissemination in the host. We show that GtrS and GltR form a two-component system that regulates the expression from the promoters Pedd/gap-1, PoprB and Pglk, which control the expression of ...

1 Introduction 2 Advantages of using M. truncatula to study resistance to fungal necrotrophs 3 Fungal pathogens of M. truncatula 4 New pathogens and isolate validation 5 References 1 Introduction Fungal diseases in plants are almost exclusively members of the phylum Ascomycota and subphylum Pezizomycotina. All common crop plants are susceptible to fungal disease of one kind or another. Spore pr...

We have previously shown that the Pseudomonas aeruginosa toxA regulatory protein PtxS autoregulates its own synthesis by binding to a 52-bp fragment. The 3' end of the 52-bp fragment is located 58 bp 5' of the ptxS translation start site. We have identified a 14-bp palindromic sequence (TGAAACCGGTTTCA) within the 52-bp fragment. In this study, we used site-directed mutagenesis and promoter fusi...

Objective: The study aimed to molecular characterization of Pasteurella multocida local strain using Enterobacterial Repetitive Intergenic Consensus (ERIC), 13 virulence genes and the outer membrane protein (OmpH) gene. Also, development of diagnostic markers by multiplex PCR from investigated genes. Methodology: The ERIC-PCR was used for the detection of the finger print of Pasteurella multoci...
