conclusions bovine rotavirus presents 6% of calf diarrhea in pakistani cattle and buffalo samples. the vp4 and vp6 genes show closed relationships with bovine rotavirus reported from indian isolates. background group a bovine rotaviruses (brv) are one of the main factors of neonatal calf diarrhea and mortality around the world. the current study was carried out to assess the genetics of brv cir...

accurate and rapid diagnosis of human cytomegalovirus (hcmv) disease in immunocompromised patients has remained as a challenge. quantitative competitive pcr (qc-pcr) methods for detection of hcmv in these individuals have improved the positive and negative predictive values of pcr for diagnosis of hcmv disease. in this study we used qc-pcr assay, using a co-amplified dna standard, to quantitate...

conclusions hepatitis b core antibody immunoglobulin m positivity is different in healthy blood donors of different countries according to the prevalence of chronic hepatitis b and its vaccination. based on the current study findings, all positive samples of hepatitis b core antibody in iranian blood banks should be considered as candidates for occult hepatitis b not just the window period infe...

background bovine viral diarrhea (bvd) is an economically important disease of cattle with a worldwide distribution. diagnosis of bvd relies on laboratory-based detections of its viral causing agent or virus specific antibodies. the most common laboratory method used for this purpose is the elisa. bovine viral diarrhea virus (bvdv) nonstructural protein 3 (ns3) is one of the most highly conserv...

results primary, secondary, and 3d structure of cchfv gn were obtained and pcr reaction with m13 forward and reverse primers confirmed the generation of recombinant bacmid dna harboring gn coding region under polyhedron promoter. conclusions characterization of the detailed structure of cchfv gn by bioinformatics software provides the basis for development of new experiments and construction of...

background autoimmune hemolytic anemia is a hematologic disorder that is rarely observed in infants and young children. most of the cases are associated with viral or bacterial infections. in some cases, aiha can be characterized by a chronic course and an unsatisfactory control of hemolysis, thus requiring prolonged immunosuppressive therapy. case report especially in children younger than 2 y...

Introduction: Nitazoxanide is an oral anti-parasitic agent that has been found to have broad antiviral activity. Its role in the treatment of viral gastroenteritis is not well-studied. Given the worldwide prevalence of viral gastroenteritis, particularly in developing nations, a systematic review of this topic would be valuable. Methods: A formal literatu...

Background: During the recent years, significant progress has been achieved on development of novel anti-viral drugs. Natural products are assumed as the potential sources of novel anti-viral drugs; therefore, there are some previous studies reporting the anti-viral compounds from venomous animals. Based on the significant value for tracing of non-toxic anti-viral agents from natural resources,...
