Background/aim: Parvovirus risk in blood transfusion has become a popular research topic since there are limited data on parvovirus seroprevalence in blood donors in Turkey. The aim of this study was to investigate parvovirus seroprevalence in blood donors in Turkey. Materials and methods:Blood samples of 988 blood donors admitted to a university blood bank were obtained for parvovirus B19 IgM and IgG detection. The samples were analyzed using the ELISA method.Results: IgM positivity of 3.92% and IgG positivity of 58.9% was detected in the blood samples. Parvovirus IgM positivity was found to be the highest in the age group of 41-50 years (P = 0.045) and IgG positivity was detected to be the highest in the age group of 31-40 years (P < 0.001). Parvovirus IgG positivity was significantly higher in women (P = 0.041). However, there was no difference regarding parvovirus IgM positivity in terms of sex (P = 0.245). Conclusion:Although this study does not represent the whole country, it is still the largest investigation carried out on the topic in Turkey and the obtained results are generally similar to those of European countries. Therefore, it is thought that the results obtained from this study may be supportive for the first steps regarding plasma fractionation, which will soon begin in Turkey.

Sonuç olarak, solunum yolu enfeksiyonu etkeni izolatların direnç oranlarındaki artış dikkat çekici bulunmuştur. En yaygın saptanan izolatlar olan A. baumannii ve K. pneumoniae'nın tüm antibiyotik gruplarına yüksek direnç oranları göstermesi endişe vericidir. Doğru antibiyotik kullanımı için belirli zaman aralıklarında SYE'li hastalardan izole edilen bu tür mikroorganizmaların dağılım ve direnç profillerini gösteren çalışmaların yapılması gereklidir. Sonuçların ampirik tedavi protokollerinin güncellenmesinde ve klinisyenlerin doğru antibiyotik kullanımı konusunda yönlendirilmesinde yararlı olacağı düşünülmektedir.

Introduction: Rotavirus infection is a major cause of morbidity and mortality in infants and young children with diarrhea throughout the world. Material and Methods: In this study, we aimed to determine the detection rate of rotavirus infection in 181 children less than 5 years of age presenting with acute gastroenteritis and admitted to a tertiary care hospital in Ankara, Turkey, from April to November 2012. We documented the epidemiological data by elucidating the prevalent genotypes. Stool specimens were collected, and rotavirus antigen in the samples was detected using ELISA. G and P genotypes were determined by RT-PCR via type specific primers. The nucleotide sequence of the concerned genes was determined by Sanger sequencing and phylogenetic analysis was performed by neighbor-joining method. Results: Of the 181 samples, 28 (15.5%) were positive for the rotavirus antigen. Twenty-seven samples were positive for G genotypes and 21 were positive for P genotypes. Genotypes G1 (7.1%), G2 (7.1%), G3 (7.1%), G4 (3.6%), G9 (71.5%) and P4 (3.6%), P8 (71.4%) were identified. Genotype G9P[8] (50%) was predominant in the combination of G and P genotypes. Most of the G9 strains of this study formed an independent cluster in Lineage III, except two strains which clustered with an Ethiopian G9 strain of 2012. Conclusions: It seems that during 2012 season, genotype G9P[8] increased significantly in Ankara due to a new circulating strain of G9.
