[Investigation of Cryptosporidium sp. in workers of the Van municipality slaughterhouse and in slaughtered animals].

This study was carried out in order to investigate the prevalence of Cryptosporidium sp. in slaughtered animals and workers of the Van municipality slaughterhouse in Van. Animals slaughtered at different times and workers who had been working in different departments of the slaughter house were included in the study for three months. A total of 309 fecal specimens from animals including 167 sheep, 56 goats and 86 cattle and 87 fecal specimens from workers were examined for Cryptosporidium sp. oocysts. In slaughtered animals, the modified acid-fast staining method was used to determine the oocysts of Cryptosporidium sp. The fecal samples of slaughter workers were examined by using RIDA (R) Quick Cryptosporidium Strip Test (R-Biopharm, Germany) and the modified acid-fast staining method. Fecal samples found to be positive by stripe test were also confirmed with the ELISA method (R-Biopharm, Germany). Oocysts of Cryptosporidium sp. were found in fecal specimens of 22 sheep (13.17%), 6 goats (10.71%) and 7 cattle (8.13%). Intestinal parasites were observed in 34 fecal specimens of workers (39.08%). Cryptosporidium sp., Hymenolepis nana, Chilomastix mesnili, Endolimax nana, Iodamoeba bütschlii were found in the specimen of one worker (1.14%), Entamoeba coli in 4 workers (4.59%), Blastocystis hominis (9.19%) in 8 workers, and Giardia intestinalis (19.54%) in 17 workers.
