We have reviewed the incidence, type and site of microbiologically proven bacterial infection occurring in 52 patients with the acquired immunodeficiency syndrome (AIDS) who presented to Southmead Hospital, Bristol between 1990 and 1994. A total of 30 (58%) patients had significant bacterial isolates. The majority of infections were community acquired. Overall, more infections were caused by Gr...

Non-pigmented strains of Pseudomonas pyocyanea occur frequently and this organism has only limited activity in conventional biochemical tests; 50 strains were tested for the presence of arginine dihydrolase and found positive whereas only Salmonella sp. and Enterobacter sp. among other Gram-negative species were positive. The test for arginine dihydrolase is rapid and simple and suitable for ro...

region. regulatory oxidative operon, and analysis of the activator of the tcbCDEF chlorocatechol P51 gene tcbR, a LysR-type transcriptional Characterization of the Pseudomonas sp. strain

We investigated the role of the surfactant proteins (SPs) A and D in the pulmonary immune defense of nonmucoid strains of Pseudomonas aeruginosa, the most etiologic agents of nosocomial Pseudomonas pneumonia. We first examined the interactions of recombinant human SP-D dodecamers and purified natural or recombinant human SP-A with two smooth, and two rough, clinical isolates of nonmucoid P. aer...

Of a sample of 42 gram-negative Hg-resistant bacteria, three (a Pseudomonas fluorescens, a Klebsiella sp. and a Citrobacter sp.) contained translocatable elements conferring resistance to Hg2+ (all three) and to Hg2+ and phenylmercuric acetate (P. fluorescens). The discovery of transposable phenylmercuric acetate resistance extends the range of known resistance "transposons" from heavy metals a...

Pedobacter sp. strain V48 participates in an interaction with Pseudomonas fluorescens which elicits interaction-induced phenotypes. We report the draft genome sequence of Pedobacter sp. V48, consisting of 6.46 Mbp. The sequence will contribute to improved understanding of the genus and facilitate genomic analysis of the model interspecies interaction with P. fluorescens.

Polythene plays an important role in packaging of goods, food material, medicine and garbage bags etc but its degradation is becoming a great threat and vital cause of environmental pollution. There are various polythene degradation methods available but the eco-friendly and acceptable method is by using microbes. The present study deals with the isolation, identification, screening and degrada...

OBJECTIVE To study on the distribution of bacterial keratitis isolates and the resistance to antibiotics in China from 2001 to 2004. METHODS 1985 specimens from the bacterial keratitis at the Beijing Tong Ren Eye Center were cultured and identified. In vitro susceptibility testing of positive isolates to antibiotics was determined by the Kirby-Bauer disk diffusion method and interpreted accor...

Pseudomonas sp. strain YS-1p and Rhizobium sp. strain YS-1r were isolated from a lignin-degrading enrichment culture. The isolates degraded lignin-derived monomers, dimers, alkali lignin, and, to a smaller extent (3% to 5%), lignin in switch grass and alfalfa. Genome analysis revealed the presence of a variety of lignin-degrading genes.

Pseudomonas sp. strain AZR1 and Klebsiella sp. strain AZR2 were isolated from reconstituted instant chocolate puddings that had turned green and were found to have azoreductase activity. This activity was inducible and NADH dependent. Differences in dye reduction rates between the two strains were apparent, and substrate specificity related to dye structure was observed.
