Serum and Nasal Secretion Immune Response in Meningococcal Disease

Effect of dietary chitosan on immune response and disease resistance in Cyprinus carpio

BACKGROUND: Occurrence of resistance against antibioticsand inadequate efficacy of some vaccines necessitates studies ofnatural immunostimulators in aquaculture. Shrimps shell derivedfrom Chitosan can be used as immune stimulators in fish.OBJECTIVES: In this study, the effects of oral administration ofchitosan, derived from shrimp shell, on some immune responsesand disease resistance in Cyprinu...

Cross-reacting serum opsonins in patients with meningococcal disease.

We have examined the opsonic activity of sera from patients with Neisseria meningitidis (B:15:P1.16) infections against different meningococcal strains, using flow cytometry and luminol-enhanced chemiluminescence. A marked increase in the phagocytosis of ethanol-fixed meningococcal strains of different serogroups, serotypes, and serosubtypes was demonstrated in the presence of convalescence ser...

Humoral Immune Response Induced by PLGA Micro Particle Coupled Newcastle Disease Virus Vaccine in Chickens

This experiment was conducted for evaluating the humoral immune responses induced by Poly Lactide-co-Glycolide Acid (PLGA) microspheres coupled inactivated Newcastle Disease Virus (NDV) vaccine in comparison to an ‘in-house’ prepared inactivated and a live commercial vaccine. PLG microparticles containing inactivated NDV were prepared by a double emulsion technique based on solvent evaporation ...
