Brucella abortus agglutinins in the sera of pregnant women and blood donors.

چکیده
The incidence of brucellosis in the human population of England and Wales is still not accurately known, although estimates have been made (Wilson, 1932; Dalrymple-Champneys, 1950). Few persons who acquire Br. abortus develop any obvious clinical disease, but the existence of Br. abortus agglutinins in blood sera indicates past exposure to the organism. A survey of human and animal brucellosis made between 1957 and 1959 in the Oxford area (Bothwell, 1960 a, b, c, 1961; McDiarmid, 1960a, b, 1961) included the examination of 3,431 sera samples from pregnant women and of 8,690 samples of sera from blooddonorsforthepresenceofBr.abortusagglutinins. Both types of sera are readily available; both have limitations for survey purposes. Blood donor serum cannot be regarded as a normal sample compared with a cross-section of the general population, since blood donors are in fact highly-selected healthy persons. The serum from pregnant women also constitutes a selected sample. The incidence of agglutinins in both samples may represent an underestimate of the incidence of agglutinins in the general population. The results of both surveys are given, with notes on the investigation of milk supplies consumed by pregnant women with agglutinins to Br. abortus.

Low Prevalence of Brucella agglutinins in Blood Donors in Central Province of Iran
BACKGROUND AND OBJECTIVE Brucellosis is a zoonotic disease of worldwide distribution and has great economic importance. Despite its control in many countries, it remains endemic in Iran. Brucellosis was investigated in many high risk occupational groups; however, few studies on the prevalence of brucellosis among blood donors are available. To determine the seroprevalence of brucellosis antibod...

F(1) hybrid chicks isogenic for the strong B histocompatibility locus and for most weak H-loci were X-irradiated on day 1 after hatching, injected intraperitoneally on day 2 with dispersed cells of bursa, spleen, or thymus from 4- or 10-wk-old F(1) hybrid donors, and immediately challenged by the same route with either Brucella abortus, sheep erythrocytes, or a mixture of both together. The agg...

Brucellosis, caused by Brucella spp., is an important zoonotic disease that causes abortion and infertility in cattle and undulant fever in humans. Various studies have examined cell-free native and recombinant proteins as candidate protective antigens in animal models. Among Brucella immunogenes, antigen based on ribosomal preparation has been widely investigated. In this study, the immunogeni...

Background: Lipopolysaccharides (LPSs) and several antigenic proteins of Brucella have been considered for preparation of diagnostic reagents and subunit vaccines. The objective of this study was to identify and compare immunogens of B. abortus S19 which induce humoral immune responses in human, goat and rabbit. Material and Methods: The bacterial whole cell extract was prepared in extraction b...
