[ 1 ] - Antimicrobial Susceptibility of Stenotrophomonas maltophilia Clinical Isolates from Blood Samples in Iran
Introduction: Stenotrophomonas maltophilia is a nosocomial multi drug resistant opportunistic pathogen which causes infections in vulnerable patients with cancer, cystic fibrosis and indwelling catheters. Methods: 45 clinical S. maltophilia isolates were collected from blood samples and identified by biochemical tests. Susceptibility to different antibiotics including co-trimoxazole, levofloxac...
[ 2 ] - Isolation and characterization of Faecalibacterium prausnitzii extracellular vesicles
Introduction: Extracellular vesicles (EVs) contain active biological compounds which play important roles in biological processes. The secretion of EVs is a common phenomenon which occurs in archaea, bacteria and mammalian cells. The secretion of bacterial EVs has been discovered in various species of both Gram-negative and Gram-positive bacteria. Faecalibacterium prausnitzii is one of the comm...
[ 3 ] - Cloning and expression of porA gene as the first step of a vaccine candidate study against Neisseria meningitidis serogroup A infection
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 ...
[ 4 ] - New insight into the application of outer membrane vesicles of Gram-negative bacteria
This review presents a brief outline of our current knowledge of the structure and chemical composition of the outer membrane vesicles (OMVs), originating from the surface of Gram negative bacteria including their outer membrane proteins and lipopolysaccharides. Moreover, the functional roles and applications of OMVs in medical research such as OMV-based vaccines, OMV adjuvants properties, OMV ...
[ 5 ] - Protein profiling and analysis of drug sensitive and multidrug resistant isolates of Mycobacterium tuberculosis by native polyacrylamide gel electrophoresis and mass spectrometry
Introduction: Tuberculosis (TB) remains a deadly infectious disease despite all the efforts to reduce its incidence. Spread of multidrug resistant TB has seriously undermined the efforts to control the disease globally. In this study protein expression profile of MDR and sensitive isolates of MTB were analyzed and compared in order to identify proteins, which could be used in prevention, diagno...
[ 6 ] - Construction and assessment of the immunogenicity and bactericidal activity of fusion protein porin A from Neisseria meningitidis serogroups A and B admixed with OMV adjuvant as a novel vaccine candidate
Objective(s): The porins A and B and also outer membrane vesicles (OMVs) of Neisseria meningitidis are used for vaccine purposes. In the present study, we aimed to design a new vaccine candidate based on a fusion of PorA of serogroups A and B of N. meningitidis admixed with OMV and evaluate it in an animal model.Materials and Methods: Af...
[ 7 ] - Interaction between Intestinal Microbiota and Serotonin Metabolism
Gut microbiota regulates the production of signaling molecules, such as serotonin or 5-Hydroxytryptamine: 5-HT in the host. Serotonin is a biogenic amine that acts as a neurotransmitter in the gut and brain. There is a perfect interaction between human gastrointestinal microbiota and the serotonin system. The gut microbiota plays an important role in the serotonin signaling pathways through the...
