background: the risk for transmission of blood-borne viruses (bbvs) such as human immunodeficiency virus (hiv), hepatitis b virus (hbv) and hepatitis c virus (hcv) due to occupational exposure is a major concern in the health care setting. m aterials and methods: this study among 337 health care workers (hcws) accidentally exposed to bbvs was carried out from january 2009 to march 2015. the dat...

background meningitis is an inflammation of the membranes, which surround the brain and spinal cord. early treatment of bacterial meningitis can prevent serious complications. in the last two decades, three vaccines have been developed against the three main bacterial species implicated in meningitis of children in western countries and vaccine-preventable invasive bacterial meningitis has decr...

abstract background: in recent years, infrared thermography tools are used for viral disease detection. however, no study has been to evaluate the value of this device. the current study was designed to review the effectiveness of infrared thermography technique for diagnosis of viral diseases in international airports. materials and methods: this study was conducted as a systematic review. all...

background although certain hbv mutations are known to affect the expression of hepatitis e antigen, their association with hbv viral level or clinical outcomes is less clear. objectives we evaluated associations between different mutations in the basal core promoter (bcp) and pre-core (pc) regions of hbv genome and subsequent changes in hbv viral dna level over seven years in a population of u...

results based on our results, mab against recombinant erns was produced and reacted successfully with recombinant and natural antigens. conclusions with regards to the role of erns in the identification of pi animals, it appears that erns recombinant antigen and the specific monoclonal antibodies produced against it may be suitable for developing bvdv laboratory diagnostic assays. objectives er...

background hepatitis c virus (hcv) infection is one the major health concern among the infected transplant patients. considering several complications of the disease in them, pre and post-transplantation studies should be performed for monitoring of the infection, as well as, developing new treatment protocols. objectives the current study was conducted to determine the hepatitis c virus rna le...

respiratory disorders are major concern for dairy cattle industry. viruses and bacteria in combinationwith stress play a key role in triggering acute respiratory infections. the most important viral agents arebovine viral diarrhoea virus (bvdv), bovine herpes virus type 1 (bhv-1), bovine respiratory syncytial virus(brsv), parainfluenza virus type 3 (piv-3) and bovine adenovirus (bav). this cros...

â  â  hepatocellular carcinoma (hcc) is a major worldwide public health concern. despite recent advances, there has been little success in improving the survival of hcc patients. due to advances in diagnostic modalities and the increasing incidence of chronic viral hepatitis and nonalcoholic fatty liver disease (nafld), both of which are well known risk factors of hcc, the prevalence of hcc is ...

1320 blood samples were collected from herds showing clinical signs of pestiviral infections. 39 samples were positive in ag-elisa assay. all these 39 samples in addition to 5 cytopathic strains were cultured in md-bk cell line and presence of pestiviral antigens was confirmed by direct-immunofluorescent test. 27 out of 44 bvdv suspected isolates were detected by rt-pcr using a primer set. diff...
