Role of host immunity and HBx among inactive chronic hepatitis B patients in a highly endemic region.

The hepatitis B virus (HBV) infection has a wide range, from fulminant hepatitis to inactive chronic hepatitis B (ICB) infection. The present study evaluated critical factors in the outcomes of HBV infection in a highly endemic region of Iran (approximately 12% HBV positive). The expression of seven genes involved in host immunity (Foxp3, T-bet, ROR-γt, AKT, CREB, IL-28/or IFN-λ2, and IL-28R) and HBx for viral activities were evaluated using real-time PCR, TaqMan method.

Comparison of four methods for isolation of Yersinia enterocolitica from raw and pasteurized milk from northern Iran.

Four methods for isolation of Yersinia enterocolitica from raw and pasteurized milk from northern Iran were compared. Three hundred and ten raw milk samples were collected from tanks on their arrival at various central dairies, and 40 pasteurized milk samples were collected from tanks on their arrival at a manufacturing plant. Each sample was examined for the presence of Y.
