the objective of this study was to describe the seroprevalence rates of bluetongue virus (btv) in sheep in west and northwest provinces of iran. bluetongue virus, an economically important orbivirus of the reoviridae family, causes a hemorrhagic disease mainly in sheep and occasionally in cattle and some species of deer. bluetongue virus is transmitted between its mammalian hosts by certain spe...

conclusions based on the findings of this study, s. aureus enterotoxin c (sec) has been detected in synovial fluid of patients with rheumatoid arthritis by pcr and elisa methods. these valuable findings may describe the exact etiology of the ra and as well as change the methods of its diagnosis and treatment. this is the first research, which has shown the staphylococcal entc gene in synovial f...

APPLICATION OF ENZYME-LINKED IMMUNOSORBENT ASSAYS FOR THE DIAGNOSIS OF BOVINE BRUCELLOSIS IN RIO GRANDE DO SUL, BRAZIL. The results of an indirect ELISA (I-ELISA) and a competitive ELISA (C-ELISA) for detection of antibody to Brucella abortus in cattle were compared with those of conventional serological tests. The sensitivity of I-ELISA using 230 sera from infected animals was 98.6% and the sp...

Herein, we presented the first report on bluetongue (BT) disease in 10 pregnant camels in a herd fromKerman province, Iran. All sera samples were tested serologically (AGID, C-ELISA). We also used the Razi-BK cell line, performed primary culture of ovine kidney and inoculated intravenously the embryonatedchicken eggs (ECE) to culture and isolate the BT virus. Efforts to culture and isolation of...

Bluetongue (BT) is an infectious, noncontagious, arthropod-borne viral disease, principally of sheep but many domestic and wild animals are also affected by this disease (Akita et al., 1994). The severity of BT in sheep varies depending on the virus, the breed of sheep and environmental stress. Infection in cattle and goats is usually sub-clinical. Etiological agent of the disease belongs to th...

Bertino, Ferrari and Atluri (BFA) have recently presented a model for specifying and enforcing authorization constraints for Workflow Management Systems (WFMS). The model is comprehensive and exhibits strong properties such as (1) a language to express constraints, (2) formal notions of constraint consistency and (3) algorithms for role-task and user-task assignments. In this paper, we extend t...

Recently, IACR ePrint archive posted two fully homomorphic encryption schemes without bootstrapping. In this note, we show that these schemes are trivially insecure. Furthermore, we also show that the encryption schemes of Liu and Wang [6] in CCS 2012 and the encryption scheme of Liu, Bertino, and Xun [5] in ASIACCS 2014 are insecure either.
