Toxoplasmosis is a zoonotic infectious disease that is common worldwide and caused by the Toxoplasma gondii. Congenital toxoplasmosis is one of the major complications of this infection. The present study aimed to investigate T.gondii seroprevalence and evaluate the IgG avidity test results among childbearing- age women retrospectively. A total of 9401 samples obtained from childbearing -age (15-49 years of age) women who attended Karabuk University Training and Research Hospital between February 2016- January 2020, over the four-year, were included in the study.The Toxoplasma-IgM, Toxoplasma-IgG antibody, and Toxoplasma IgG avidity tests were analyzed chemiluminescent method by using ARCHITECT I 2000 SR immunoassay device (Abbott Laboratories, USA). Toxoplasma-IgM and Toxoplasma-IgG seropositivity were detected as 0.7% (67/9401) and 15.7% (1415/9005) respectively. A high percentage of Toxoplasma-IgM and Toxoplasma-IgG seropositivity were detected among 31-35 years of age group. The Toxoplasma seropositivity increased by age, but no statistically difference was found (P >0.05).The Toxoplasma IgG avidity was high in 45 patients (69.4%), low avidity was detected in 16 patients (22.6%) and from the remaining 6 patients were borderline (8%). The Toxoplasma IgM and IgG seropositivity rate decreased 2016 to 2020. The highest Toxoplasma IgM and IgG seropositivity were in 2016 with 1.2% and 16.8%, respectively. The T. gondi seropositivity rate was decreased from 2016 to 2020; it is probably a result of increasing awareness of the disease among patients. We think our results will contribute to the epidemiological data in our province and country and raise awareness.

Background/aim: To determine the frequency, genotype distribution, and genetic relatedness of adenoviruses in children under 5 years old with diarrhoea and to investigate their distribution according to clinical findings, age, months, and seasons.Materials and methods: Stool samples were collected from 180 children with acute gastroenteritis who presented from July 2007 through June 2011 at the Ankara Training and Education Hospital. Stool samples were analysed by immune chromatographic test (ICT), enzyme immunoassay (EIA), and polymerase chain reaction (PCR). All adenovirus types were determined by nucleotide sequence analysis. A phylogenetic tree was constructed by Mega 6.0 using the neighbour-joining method.Results: Five percent of the samples were positive for adenovirus (9/180) by ICT, 6.1% (11/180) by EIA, and 13.9% (25/180) by PCR. Adenovirus gastroenteritis did not show any differences in age group, sex, month, or season. In this study, 16 (64%) of the PCR positive samples were AdV41, 6 (24%) were AdV40, 2 (8%) were AdV31, and 1 (4%) was AdV7, as determined by nucleotide sequencing. Conclusion:AdV31 and AdV7 were associated with gastroenteritis. Adenovirus serotypes showed a similarity of 80% (20/25) and 20% (5/25) with Asian and American serotypes, respectively.
