To determine the prevalence and genotype distribution of rotaviruses in children presenting to authors’ hospital in Middle Black Sea region of Turkey. The results may supply important information about vaccine studies in Turkey.
Rotavirus antigen was detected by latex agglutination test and rotavirus RNA was detected by RT-PCR test. On the other hand, rotavirus positive samples were genotyped by semi-nested multiplex polymerase chain reaction.
The highest rate of rotavirus positivity (46.9%) was observed among children in the 13 to 24 mo age group. All the positive-strains were in G1–4, G8–9, P , P , and P  genotypes. The most common G and P combination in present study was G9P (n = 24, 28.9%).
The present results indicated that the most prevalent genotypes were G1, G9, P8, G9P and G1P in authors’ region. Rotavirus vaccines used in this region must include mainly these genotypes.

YB and GY: Provided the samples, did analysis and interpretation of the data; RD: designed the study and was responsible for genotyping. All the authors participated in writing and critical review of the manuscript. RD will act as guarantor for the paper.
Compliance with Ethical Statement
This study was approved by the ethics committee of the Ministry of Health, Dr. Abdurrahman Yurtaslan Oncology Training and Research Hospital, Ankara/Turkey (Protocol code: 2012–8/37). The verbal consent of parents of the child enrolled in this study was obtained prior to the sample collection. Because collection of fecal samples from children with suspected rotavirus infection being admitted to the hospital was a routine process for rotavirus diagnosis, verbal consent was approved by the ethics committees.
