Hepatitis B virus genotype E detected in Brazil in an African patient who is a frequent traveler

Abstract: Genotype E of hepatitis B virus (HBV) has not been described in Brazil and is found mainly in Africa. Genotype A is the most prevalent in Brazil, and genotypes B, C, D, and F have already been reported. We report here an HBV genotype E-infected patient and some characterization of surface (S) protein, DNA polymerase (P) and precore/ core (preC/C) coding regions based on the viral genome. The patient is a 31-year-old black man with chronic hepatitis B who was born and raised in Angola. He has been followed by a… Show more

“…Genotype E is thought to be the most recent genotype originating in Africa. It is exclusively found in Africa or in African descendants living worldwide (Bekondi et al 2007, Kramvis & Kew 2007, Palumbo et al 2007, Sitnik et al 2007). Within Africa, it has a higher prevalence in Western African countries, including Senegal, Cote d'Ivoire, Ghana, Nigeria and Namibia (Dumpis et al 2001, Kramvis et al 2005, Kramvis & Kew 2007).…”

“…It is already known that genotype E is largely found only in Africa or African descendents and is very rare in any other continent. Currently, the few HBV/E carriers found outside Africa were recent travellers from this continent (Halfon et al, 2006;Palumbo et al, 2007;Toro et al, 2006;Liu et al, 2001;van Steenbergen et al, 2002;Mathet et al, 2006;Sitnik et al, 2007;Kato et al, 2004). The fact that Quibdó (the Colombian city from where the samples in this work were isolated) inhabitants are descendent from the slaves that arrived in America up to the beginning of the 19th century raises the question of when this genotype was introduced in this population.…”

“…In Europe, sporadic genotype E strains were reported from France (Halfon et al, 2006), Italy (Palumbo et al, 2007), Spain (Toro et al, 2006), Belgium (Liu et al, 2001) and The Netherlands (van Steenbergen et al, 2002). Others cases were reported in Argentina (Mathet et al, 2006), Brazil (Sitnik et al, 2007) and the USA (Kato et al, 2004).…”
