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...
The decoration of the lipid A headgroups of the lipooligosaccharide (LOS) by the LOS phosphoethanolamine (PEA) transferase (LptA) in Neisseria spp. is central for resistance to polymyxin. The structure of the globular domain of LptA shows that the protein has five disulphide bonds, indicating that it is a potential substrate of the protein oxidation pathway in the bacterial periplasm. When neis...
In a quantitative bacteriological study of the salivary flora from 50 children the following aerobic organisms were identified and enumerated: alpha-haemolytic streptococci, beta-haemolytic streptococci, Streptococcus faecalis, pneumococci, Staphylococcus aureus, Staph. albus and Staph. citreus, Neisseria spp, N. meningitidis, corynebacteria, aerobic lactobacilli, B. subtilis, H. influenzae, co...
The penicillin-binding protein 2 genes (penA) of penicillin-resistant Neisseria meningitidis have a mosaic structure that has arisen by the introduction of regions from the penA genes of Neisseria flavescens or Neisseria cinerea. Chromosomal DNA from both N. cinerea and N. flavescens could transform a penicillin-susceptible isolate of N. meningitidis to increased resistance to penicillin. With ...
