The study identifies the prevalent rotavirus strains in Tunisia between 1995 and 1999, highlighting the emergence of natural human reassortants.
Strain surveillance in 1990s Tunisia highlights reassortant emergence; leaves open current genotype distribution and vaccine implications.
Rotavirus strains circulating in Sousse, Tunisia, between 1995 and 1999 were characterized antigenically by monoclonal antibodies to the VP6 subgroup and the VP7 serotype. The VP4 genotype was determined by reverse transcription-PCR, as were the strains with untyped VP7. Only 17% of 375 children were shedding rotavirus as determined by latex agglutination assay. Most rotavirus strains were G1P[8] (50%), followed by G4P[8] and G4P[6]. Reassortant G1P[4] strains emerged in Sousse during the 1998-1999 season.
