Pseudomonas aeruginosa is one of the major pathogens responsible for a wide variety of severe nosocomial and community acquired infections. Numerous vaccine candidates and several monoclonal antibodies have been developed over the past 40 years but only a few have reached clinical trials and none of these vaccine candidates has obtained market authorization. The understanding of P. aeruginosa p...
The research was aimed to demonstrate the frequency of virulence factors genes (exoenzyme S and exotoxin A) express their relationship antibacterial resistance among Pseudomonas aeruginosa isolated from patients suffering otitis externa. results were revealed that only twenty one (32%) out 65 clinical ear swabs aeruginosa. According PCR amplification, 18 (85.7%) bacterial isolates expressed bot...
Phagocytosis of bacteria by macrophages and neutrophils is an essential component of host defense against infection. The mechanism whereby the interaction of opsonized particles with Fcgamma receptors triggers the engulfment of opsonized particles remains incompletely understood, although activation of tyrosine kinases has been recognized as an early step. Recent studies in other systems have d...
Mouse monoclonal antibodies raised by immunisation with a protective antigen extract from Pseudomonas aeruginosa serotype 1 varied in immunoglobulin isotype, in passive protective properties against infection by homologous P. aeruginosa serotype 1, and in cross-reactions in ELISA against antigen preparations from 15 other P. aeruginosa serotypes. All monoclonal antibodies with specificity in EL...
Bacterial persister cells constitute a small portion of a culture which is tolerant to killing by lethal doses of bactericidal antibiotics. These phenotypic variants are formed in numerous bacterial species, including those with clinical relevance like the opportunistic pathogen Pseudomonas aeruginosa. Although persisters are believed to contribute to difficulties in the treatment of many infec...
PepP is a virulence-associated gene in Pseudomonas aeruginosa, making it an attractive target for anti-P. aeruginosa drug development. The encoded protein, aminopeptidases P (Pa-PepP), is a type of X-prolyl peptidase that possesses diverse biological functions. The crystal structure verified its canonical pita-bread fold and functional tetrameric assembly, and the functional studies measured th...
