Statistics in Infection and immunity revisited.

Immunity in experimental murine filariasis: roles of T and B cells revisited.

We have reevaluated the contributions of T and B cells in Brugia malayi infection by utilizing knockout mice on a uniform background (C57BL/6J). We find that B-cell-deficient mice are more permissive to infection than T-cell-deficient mice.

THE ROLE OF B-CELLS IN THE DEVELOPMENT OF IMMUNITY TO CRYPTOSPORIDIUM INFECTION

Studies have shown that symptomatic improvement of cryptosporidiosis in immunocompromised patients is possible following treatment with" hyperimmune" colostrum containing anti-sporozoite antibodies from cattle immunized with Cryptosporidium parvum antigens. The contribution to immunity of antibodies developed during Cryptosporidium infection is unclear, however. Previously, we showed that ...

Comparison of living vaccines in producing immunity against natural brucella melitensis infection in sheep and goats in Iran

بررسی مقایسه‌ای سرولوژی اریون در کودکان مبتلا به کاهش شنوایی حسی عصبی و کودکان غیرمبتلا Comparative Study of Mumps Serology in SNHL Children and Unaffected Ones

    Background & Aim: Mumps infection is endemic in Iran. Due to high percentage of unvaccinated young people(10y(2.1%). Acute mumps infection(positive IgM) was seen in 8.3% and previous immunity to mumps(IgG) in 24.1% of all. The highest incidence of acute infection(IgM) was in 3-5-year old group, but it was not different in other age groups(P=0.11). Previous infection(IgG was also higher in 3...

Immunity Against Avian Influenza Viruspanax Ginseng Polysaccharide (GPS) Can Improve Immunity Against H9N2 Avian Influenza Virus in Chickens

The humoral immunization potential of panax ginseng polysaccharide (GPS) against H9N2 avian influenza virus (H9N2 AIV) in chickens was investigated. The effects of GPS treatment before and during H9N2 AIV infection were determined in chicken embryo fibroblast (CEF) by MTT (3(4, 5-dimethylthiazol-2-yl)-2, 3-diphenyl tetrazolium bromide) assays and quantitative RT-PCR analysis of MHC and cytokine...
