Serological diagnosis provides a robust and effective approach to monitoring controlling small ruminant brucellosis. Brucella melitensis Rev. 1 is live vaccine strain used in prophylactic vaccination against Because the shares identical serological antigens with corresponding field strains, differentiating infected from vaccinated animals (DIVA) responses hamper surveillance campaigns intervent...
Abstract Background and Objective: One of the proteins shared in all strains of Brucella is 31 kDa surface protein (BCPS31) that could be an appropriate target for immunization and serological diagnosis. Material and Methods: In the present study, BCSP31 produced as a recombinant protein in pET28a (+) expression system was utilized, using ELISA, to detect trace specific antibody (IgG) in brucel...
It was shown by Wiener (1944) that some human a,nti-Rh sera contained incomplete antibodies which combined with but did not agglutinate the corresponding red cells. They appeared to be more avid than agglutinating antibodies, so that, if the two kinds of antibody co-existed in the same serum, the incomplete or blocking antibody might account for failure of agglutination or for a zone of inhibit...
Brucella sp. antibodies, despite falling to low levels, can remain measurable after recovery from acute brucellosis (1). Recently, several studies have shown the persistence of Brucella sp. DNA in both chronic brucellosis patients and asymptomatic subjects with a history of brucellosis (2–4, 6). However, to our knowledge, the association between serum antibodies and Brucella sp. DNA has not bee...
The seroprevalence of brucellosis among undiagnosed family members of brucellosis positive patients.
AIM This study investigated the seroprevalence, complications and risk factors of Brucella infection in rural areas of Sivas, Turkey. MATERIALS AND METHODS The study was conducted in three hyperendemic counties for brucellosis known as Gurun, Altinyayla and Kangal in Sivas between April and October in 2011. A total of 1,430 subjects were consulted. RESULTS Of the 1,430 subjects, 217 (15.2%)...
INTRODUCTION Brucellosis in Egypt is an endemic disease among animals and humans. In endemic developing countries, dairy products produced from untreated milk are a potential threat to public health. The aim of this study was to detect brucellae in milk and milk products produced from apparently healthy animals to estimate the prevalence of contamination. METHODOLOGY Two hundred and fifteen u...
Western blotting or immunoblotting commonly use for study of reaction between antigens and antibodies. Denaturation of many proteins in immunoblotting can affect greatly the reactivity of antibodies and outcome of the procedure. In this study proteins of Brucella abortus (S19) was extracted by a mild method and reaction of the extracted proteins with serum of infected&nbs...
Background & Objective: One of the most common diseases between zoonosis - especially in developing countries – is brucellosis. Identification of Brucella cell antigen combinations in terms of the amount and type of immune response in infected hosts, are important in vaccine design. 31kDa Brucella cell surface protein (BCSP31) is shared among all Brucellae. We aimed to define specific immune r...
Cannella et al. (2012) published an article in this issue that aims at identifying serum antibodies associated with clinical manifestation of human brucellosis. They hypothesized that these antibodies can predict potential Brucella antigenic candidates, and may also have diagnostic, prognostic, and vaccine value. The authors also predicted that by elucidating the antibody profiles of groups of ...
