background: brucellosis is one of the most important zoonosis that is prevalent among human and animal. today, a large percentage of animal and human population suffer from its side effects. objectives: the purpose of the present study was to estimate the prevalence of anti-brucella antibodies in flock- and animal-level in districts of south of kerman province. methods: in this cross-sectional ...

This cross-sectional study was conducted to estimate seroprevalence and to identify flock-level factors associated with seropositivity to brucellosis in small ruminants in Kerman province, southeastern Iran. In October-November 2011, serum samples were randomly collected from 1767 sheep and 1233 goats, older than 18 months, from 300 flocks. The sera were initially screened for the presence of a...

This paper reports on a sporadic, naturally acquired infection of sheep with Brucella abortus on a privately owned farm in Toro near Bauchi, Nigeria. The abortions, which occurred in a flock of 28 Yankassa sheep, involved five ewes at the third month of gestation. Serum and milk samples from the flock were examined for Brucella antibodies by the Rose Bengal plate test, serum agglutination test ...

ABSTRACT Brucella ovis, a non-zoonotic species, is the etiological agent of ovine brucellosis, an infectious disease clinical or subclinical occurrence in sheep flocks. Until then, there no serological study anti-Brucella ovis antibodies purebred herds. This aimed to determine presence flocks with breeding purposes from Parana State. Blood samples 728 animals, which 563 were females and 165 mal...

Arctic foxes (Vulpes lagopus) are susceptible to smooth Brucella (s-Brucella) infection and may be exposed such bacteria through the consumption of infected marine mammals, as implied by finding s-Brucella antibodies in polar bears (Ursus maritimus). Svalbard have not previously been investigated for s-Brucella antibodies, but antibodies detected Iceland, Alaska (USA) Russia...

In this study, a localized surface plasmon resonance (LSPR) nanobiosensor was designed to quantify anti-Brucella antibodies in the human sera. Smooth Lipopolysaccharide (LPS) extracted from Brucella melitensis via modified hot phenol water method and fixed on of gold nanoparticles by covalent interactions with functionalized nanoparticles. To obtain best performance probe, ratio LPS nanoparticl...

Monoclonal antibodies which bind Brucella A lipopolysaccharide (LPS)-specific, M LPS-specific, or cross-reactive epitopes were used as reagents in quantitative dot blot, Western blot (immunoblot), and immunoprecipitation analysis of Brucella whole cells, whole-cell extracts, and purified LPS preparations. This set of monoclonal antibodies detected four unique epitopes on Brucella LPS. The speci...

background: brucellosis is one of the most common zoonosis in middle east and iran. objectives: the purpose of this study was genomic detection of brucella spp. in sero-positive dairy cattle. methods: we have collected 28,519 blood samples from cows during 2012-2013. samples were screened by slide and tube agglutination and 2-mercaptoethanol tests. samples with anti-brucella antibodies titer ≥ ...
