BACKGROUND The roe deer is the most abundant and widespread wild Eurasian cervid. Its populations are expanding and increasingly in contact with livestock. This may affect the distribution of infectious diseases shared with other wild and domestic ungulates. METHODS We investigated the antibody seroprevalence against Pestivirus, Herpesvirus, Bluetongue (BT) virus, M. avium paratuberculosis (M...

BACKGROUND: Brucellosis is a febrile zoonotic infectionand has worldwide distribution among humans as well asanimals. Although the seroprevalence of brucellosis in variousanimals has been described in Iran, there is only one report onequine brucellosis in the region. OBJECTIVES: This study wascarried out to determine the seroprevalence of brucellosis inracing clubs and private horse owners in t...

OBJECTIVE This study was conducted to identify the seroprevalance of diseases which are zoonotic and responsible from abortion such as toxoplasmosis, listeriosis and brucellosis in Holstein crossbred cattle of different age and sex in Adana province, between 2008 April-September. METHODS For this purpose, blood serum samples were collected from 132 cattle and analyzed for Toxoplasma gondii, L...

The few cytogenetic studies performed in both humans and animals exposed in vivo or in vitro to dioxin reported conflicting data with or without chromosome damage. Therefore the aim of this work was to fulfill the genotoxicity of dioxin and its effect on immune response of sheep vaccinated with Brucella melitensis Rev.1 vaccine. A total number of twenty female goats were divided into four group...

The lipopolysaccharide (LPS) is considered the major virulent factor in Brucella spp. Several genes have been identified involved in the synthesis of the three LPS components: lipid A, core and O-PS. Usually, Brucella strains devoid of O-PS (rough mutants) are less virulent than the wild type and do not induce undesirable interfering antibodies. Such of them proved to be protective against bruc...

Background: Using Brucella abortus Strain 19 (S19) to control bovine brucellosis is restricted due to induce antibodies to the O-side chain of the smooth lipopolysaccharide (LPS) which may be difficult to differentiate vaccinated and infected animals. Furthermore, it is virulent for humans and can induce abortion to cattle. Objectives: The aim of...

introduction: omp31 is animmunodominant and protective antigen conserved in brucella species and a good candidate for vaccine design. material & methods: the present study aimed at in silico design of the truncated omp31 (tomp31) using bioinformatic tools and to express the selected form in escherichia coli (e. coli) results and conclusion: various bioinformatically calculated scores for the mo...

Brucella abortus and Brucella melitensis have surface lipopolysaccharides and polysaccharides carrying B. melitensis-type (M) and B. abortus-type (A) epitopes as well as common (C) epitopes present in all smooth Brucella biotypes. Crude lipopolysaccharides, hydrolytic O polysaccharides, and native hapten polysaccharides of MC or AC specificity were evaluated in indirect enzyme-linked immunosorb...

Exposure of pronghorns (Antilocapra americana) in western Nebraska in 1983 to selected livestock pathogens was examined by serology and attempted virus isolation. Antibodies were present to the agents of bluetongue, epizootic hemorrhagic disease, and bovine respiratory syncytial virus. There were no serologic reactors to Brucella, and attempts to isolate the viruses of bluetongue and epizootic ...
