pasteurella multocida (p. multocida) is an important pathogen of various domestic animals. the outer membrane proteins (omps) play a major role in pathogenesis and immunogenicity of p. multocida. the aim of the study was to develop indirect enzyme linked immuno sorbant assay (elisa) based on omps to ascertain the antibody titers in animals post-infection or to gauge the potency of vaccine. the ...
Introduction: Neisseria meningitidis is a major causative agent of bacterial septicemia and meningitis in human. PorA is a major component of the outer membrane of N. meningitidis and functions as a cationic Porin. This study aimed to clone and determine the expression of PorA as the first step for producing a proper antigen in a vaccine study against N. meningitidis. Methods: An approximately ...
helicobacter pylori infections are accompanied with the release of some antigenic material into the stool. outer membranes proteins (omp) are among the major antigens of bacteria, which in comparison with other bacterial constituents have less cross-reactivity. in this study, omp of h. pylori were isolated from 11 clinical isolates and rabbit antiserum against them was used to detect possible a...
One of the main fundamental mechanisms of antibiotic resistance in Gram-negative bacteria comprises an effective change in the membrane permeability to antibiotics. The Gram-negative bacterial complex cell envelope comprises an outer membrane that delimits the periplasm from the exterior environment. The outer membrane contains numerous protein channels, termed as porins or nanopores, which are...
Chloroplasts, unique organelles of plants, originated from endosymbiosis of an ancestor of today's cyanobacteria with a mitochondria-containing host cell. It is assumed that the outer envelope membrane, which delimits the chloroplast from the surrounding cytosol, was thus inherited from its Gram-negative bacterial ancestor. This plastid-specific membrane is thus equipped with elements of prokar...
INTRODUCTION Acinetobacter baumannii is involved in various infectious diseases ranging from nosocomial community-acquired infections to those acquired following war or natural disasters. The treatment has become exceedingly difficult partly because the bacterium can form biofilms. Therefore, it is imperative to elucidate mechanisms of the biofilm formation that may be exploited to develop ther...
