    (Yonsei Univ College Medicine, 2004) Gurcan, S; Tatman-Otkun, M; Otkun, M; Arikan, OK; Ozer, B
    The aim of this study was to investigate the source and the size of a tularemia outbreak in a village located in a non-endemic area. Five patients from the same village were admitted to hospital with the same complaints all within one week of September 2001. Tularemia was suspected and a diagnosis was made after physical and anamnesis examinations. The village was visited the same week that the patients were admitted to the hospital, in the January and April 2002. The villagers were examined and screened serologically by microagglutination method and the water sources were investigated bacteriologically. A total of 14 people were found to be infected from the outbreak and the oropharyngeal form was the only clinical presentation. Antibody titers ranged between 1 : 80 and 1 : 640. The patients responded well to the aminoglycoside plus tetracycline therapy. Examination of the pipewater and three springs revealed that all the water sources were contaminated by coliforrns, however, Francisella tularensis could not be isolated in glucose-cystine. medium. Antibody levels stayed stable or decreased seven months after. Tularemia had not been reported in this area before, so the first patients were misdiagnosed. In conclusion tularemia should be considered in differential diagnosis of patients with fever, sore throat and cervical lymphadenopaties.

    Prevalence of hydatidosis and fertility of hydatid cysts in sheep in Kirikkale, Turkey
    (Akademiai Kiado, 2003) Yildiz, K; Gurcan, S
    This study was conducted in order to determine the prevalence and fertility of hydatid cysts in sheep in Kirikkale, Turkey. A total of 3.2% of 553 lambs and 50.9% of 1320 adults were found to be infected with hydatid cysts. The most common locations of cysts were in the liver and lung. Liver cysts tended to be more fertile than lung cysts (81.53% v. 76.47%), though the difference was not significant. The mean number of viable protoscoleces in the liver and lung cysts were 12,400 and 5,800, respectively. In general, 1-10 cysts were found in liver (51.8%) and lung (64.7%). The findings of this study indicate that hydatid cysts are common in sheep and the fertility rate of cysts is quite high. Sheep play an important role in the life cycle of Echinococcus granulosus in this region.
