Investigation of intestinal parasites in pig feces that are also human pathogens.

A total of 238 pig fecal specimens were collected from pig farms in Corlu (Tekirdağ), Ayazma, and Arnavutköy (Istanbul) during the summer. Out of the 238 pig specimens, 105 were from pigs younger than 6 months and 133 from pigs older than 6 months. These were investigated for intestine parasites in particular the ones that are human pathogens. Cryptosporidium spp. was detected In 21 fecal specimens (8.8%), Giardia spp. in 9 (3.7%), Balantidium coli cysts in 4 (1.6%) and Ascaris suum eggs in 9 (4.1%). Giardia lamblia were found in 8 (7.6%) of 105 pigs younger than 6 months, Cryptosporidium spp. in 12 (11.4%), Balantidium coli cysts in 2 (1.5%). In the pigs older than 6 months Giardia lamblia were found in 1 (0.7%), Cryptosporidium spp. in 9 (6.7%), Balantidium coli cysts in 2 (1.5%). and Ascaris suum eggs in 9 (6.7%). The difference in the rate of G. lamblia (p=0.01) in pigs less than 6 months and of A. suum in those over 6 months was found to be statistically significant (p=0.005). Our results revealed that pigs are important sources of these parasites.
