HCV genotype 2 (HCV-2) has a worldwide distribution with prevalence rates that vary from country to country. High genetic diversity and long-term endemicity were suggested in West African countries. A global dispersal of HCV-2 would have occurred during the 20th century, especially in European countries. In Tunisia, genotype 2 was the second prevalent(More)
HCV variants were classified into six genotypes (1–6) subdivided into several subtypes with different geographic distribution worldwide. Previous studies conducted in Tunisia showed that genotype 1 counts for more than 80 % of circulating HCV genotypes and most of the isolates belong to subtype 1b. Genotype 2 comes in the second position, however, few(More)
Human adenovirus type 8 (HAdV-8) is a main aetiological agent of keratoconjunctivitis. It has been reported from both epidemic and sporadic cases. The aim of our study was to investigate the genetic characteristics and chronological pattern of HAdV-8 strains that have been circulating in Tunisia over a 14-year period. Fourteen HAdV-8 isolates from a(More)
Coxsackievirus type B1 (CVB1) has emerged globally as the predominant enterovirus serotype and is associated with epidemics of meningitis and chronic diseases. In this report, the phylogeny of CVB1 was studied based on the VP1 sequences of 11 North African isolates and 81 published sequences. All CVB1 isolates segregated into four distinct genogroups and 10(More)
BACKGROUND Hepatitis B virus (HBV) infection is a public health problem in developing countries. HBV genotypes play major role in the evolution of infection since they were involved in different clinical presentations and response to treatment. OBJECTIVES This study was conducted to evaluate the efficiency of restriction fragment length polymorphism(More)
