The P (VP4) and G (VP7) genotypes of 167 group A rotavirus strains
obtained during the period 1996 to 1998 from 149 children living in a
suburban community in Guinea-Bissau, western Africa, were determined by
the reverse transcription-PCR technique. A total of nine combinations
including five different P types and five different G types were
identified. The globally common genotype pairs P[8], G1; P[4], G2;
P[8], G3 and P[8], G4 were underrepresented in this study area. We
found a substantial year-to-year variation in the occurrence of the
genotype combinations. In 1996 and 1997, P[6], G2 was the most
frequent, whereas P[8], G1 was more common in 1998. The unusual type
P[9], G3 and a few mixed infections were detected. Sixteen percent of
the rotavirus-positive samples were nontypeable.
