Abstrakt | Background. Rotavirus G9 genotype was thought to be the fifth most common genotype circulating amongst the population. In previous studies in Slovenia, only G1, G3 and G4 genotypes were detected. Objectives: To determine G and P genotypes of rotaviruses causing dehydrating gastroenteritis in children hospitalised at the University Medical Centre Ljubljana during the winter season 2001-2002. Some data obtained in previous years are included, too. Study design: For the G and P genotypes determination, we selected 99 of the total of 565 rotavirus positive samples. RT-PCR was carried out for G gene or partial P gene amplification. The RT-PCR product was used as a template for multiplex nested PCR using genotype-specitic primers. In untypable samples, a sequence analysis of a short segment of G or P gene was performed. From the period before July 2001, 183 stool samples were examined using the same methods. Results: Genotype G 1 was determined in 37, G4 in 6, and G9 in 28 samples out of 99. Only one sample showed a mixed infection with G1G4 genotype specifics. Following the sequence analysis of the short segment of G gene in 11 G9 genotypes, 2 different clusters of G9 genotype were determined. All samples had the same P genotype-P[8]. G9 genotype had not been detected prior to July 2001. Conclusion: Rotavirus G9 genotype emerged in Slovenia in the year 2001. Two different clusters were determined which have to be further characterised in detail. | |
