[Prevalence of anti-HCV antibodies and seroconversion incidence in five haemodialysis units in Morocco].

Dialysis patients are among groups at risk for development of hepatitis C infection (HCV). The aim of the study was to evaluate the prevalence and the incidence of seroconversion for HCV in five haemodialysis units in Morocco. The study was conducted during the period from September 2003 to September 2004.

Experimental transfection of Macaca sylvanus with cloned human hepatitis B virus.

Due to the absence of easily accessible animal models for the study of hepatitis B virus (HBV), the possibility of using Macaca sylvanus, a monkey originating from Morocco, North Africa, was investigated. Three monkeys were intrahepatically inoculated with a replication-competent head-to-tail HBV DNA plasmid dimer construct. The HBV surface antigen and HBV DNA were detected prior to alanine aminotransferase elevation in the serum of two of three HBV-inoculated monkeys at day 2 post-transfection and persisted for several weeks.
