{Abstract}: <B>UNASSIGNED: </B>Balantidium coli is a protozoan that can infect humans and non-human primates, being the domestic pigs the animals most affected by this parasite. This study aimed to compare the performance of five coprological methods for diagnosis of Balantidium coli cysts in fecal samples from pigs.<BR><B>UNASSIGNED: </B>From September to December 2019, 558 fecal samples were collected from the rectum of backyard pigs in the Bucaramanga metropolitan area, Colombia. The average age of the sampled animals was 3-4 months. Fecal samples collected were tested using the following coprological techniques: Direct examination with Lugol's iodine solution, buffered saline, centrifugation/flotation and McMaster techniques, and Ziehl-Neelsen method.<BR><B>UNASSIGNED: </B>The results indicate that B. coli cysts were diagnosed most frequently through direct examination with Lugol's iodine solution (52.7% of the samples) followed by direct examination with a buffered saline solution (37.6%). Moderate concordance (k=0.41; p<0.05) was determined between direct method with Lugol's iodine and buffered saline solution, McMaster and buffered saline (k=0.35; p<0.05), and centrifugation/flotation and buffered saline (k=0.28; p<0.05) showed a fair degree of concordance. The rest of the comparisons were classified as poor. The flotation techniques (centrifugation/flotation and McMaster) did not show good recovery of cysts.<BR><B>UNASSIGNED: </B>It is concluded that the most efficient method for diagnosing this parasitosis was to an association between direct examination with Lugol's iodine solution and buffered saline.
