Humoral immune response against two surface antigens of Chlamydia pecorum in vaccinated and naturally infected sheep

Chlamydia pecorum is a globally recognised livestock pathogen due to the significant clinical and economic impact it poses to livestock producers. Routine serological diagnosis is through a complement fixation test (CFT), which is often criticised for cross-reactivity, poor sensitivity and specificity. Although serology remains the preferred method in veterinary diagnostic laboratories, serolog...

Humoral immune response in hens naturally infected with Salmonella Enteritidis against outer membrane proteins and other surface structural antigens.

A simple procedure for obtaining surface exposed antigens of Salmonella Enteritidis is described. A heat treatment of whole bacteria in saline solution induced the release of small membrane vesicles containing outer membrane components as well as surface appendage components, such as fimbriae and flagellin. The characterization of the structural components of this extract, called HE, was establ...

PRODUCTION AND CHARACTERIZATION OF HUMORAL IMMUNE RESPONSE AGAINST MUSTARD GAS

One of the promising aspects of the immunological research on chemical war gas is to investigate the immunogenicity of some hazardous compounds such as mustard gas. Mustard gas is categorized as a "hapten" based on its physical and chemical properties. Haptenic chemicals which do not possess immunogenicity could be immunogenic experimentally when conjugated with a suitable protein carrier...

Survey on Carrier State of Sheep in Chlamydia pecorum Infection

Over the last 40 years, evidence has accumulated to suggest the ubiquitous presence of infections with intracellular bacteria of the genus Chlamydia in different livestock species. Different methods to clinical specimens substantiated such widespread, but mostly clinically unapparent, presumably low-level infections. In this initial epidemiological study, we addressed the question of chlamydial...

Humoral immune response against mycobacterial antigens in children with tuberculosis.

Different clinical outcomes of tuberculosis (TB) are related to the balance between cell-mediated and humoral immunity and may depend on environmental and individual factors including age and sex. The purpose of this study was to analyze the humoral immune response to recombinant and native mycobacterial antigens in relation to clinical presentations of pulmonary TB in children. We examined 224...
