ABSTRACT
OBJECTIVE@#To determine Blastocystis frequency and subtypes (ST) in ulcerative colitis (UC) patients and analyse some laboratory findings between Blastocystis positive and negative cases.@*METHODS@#Faecal samples from 150 UC patients in Adnan Menderes University, Training and Research Hospital were examined by direct microscopy and cultivated in Jones medium. Blastocystis positive cultures were subjected to DNA isolation and subtypes were identified by sequencing of barcode region. A retrospective analysis was conducted on C reactive protein (CRP), leucocyte counts (WBC), neutrophil counts, and sedimentation rates.@*RESULTS@#The overall positive rate of Blastocystis was 8% (12 patients) and the most abundant subtype was ST3 (eight isolates, 66.7%), followed by ST1, ST2 and ST7. Laboratory findings between Blastocystis infected and non-infected UC patients were not significantly different. Blastocystis frequency was 3.8% among the patients in active stage, while it was 11.8% among the patients in remission stage.@*CONCLUSIONS@#The present study confirms previous findings that have indicated the predominance of Blastocystis ST3 in humans and contributes additional evidence that suggests the low colonisation of Blastocystis infection in ulcerative colitis patients during active stage.

ABSTRACT
To elucidate the prevalence of congenital toxoplasmosis in Turkey. This study was conducted in the Department of Parasitology, Faculty of Medicine, Ege University, Izmir, Turkey during the period of 2006 and 2007. Venous blood before delivery and cord blood during delivery were collected from 138 women, and we observed the presence of immunoglobulin [Ig]G and IgM antibodies by Enzyme Linked Immunosorbant Assay [ELISA], western blotting, and other serologic tests. The combination of ELISA and western blotting have the greatest sensitivity among the serological techniques used. The results of the cord and venous sera were comparable with no significant difference, except for one sample. Data obtained showed that early characterization of IgG antibodies synthesized by congenitally infected newborn is important. This preliminary study sets an example to the studies that would help both in determining the incidence of congenital toxoplasmosis by screening larger populations and in preventing sequels by early diagnosis
