Intestinal Parasite Infections in Pigs and Beef Cattle in Rural Areas of Chungcheongnam-do, Korea

Abstract

The present study was performed to investigate the infection status of intestinal parasites in pigs and beef cattle in rural areas of Chungcheongnam-do, Korea. From November 2009 to April 2010, a total of 241 fecal samples of pigs and beef cattle (136 and 105, respectively) were examined by direct smear and centrifugal sedimentation methods. The overall positive rates of intestinal parasites among pigs and beef cattle were 73.5% and 4.8%, respectively, and the double-infection rate was 10.3% in pigs. Of 136 specimens from pigs, Balantidium coli, Ascaris suum, and Entamoeba spp. infections were found in 88 (64.7%), 24 (17.6%), and 5 cases (3.7%), respectively. Of 105 beef cattle, Entamoeba spp. infections were detected in 5 cases (4.8%). From these results, it is shown that pigs raised on rural farms in Chungcheongnam-do had a high B. coli infection rate and a moderate A. suum infection rate. These results demonstrate that environmentally resistant cysts or eggs could be widespread on the farms examined, and thus an effective hygienic management system is needed to prevent them from serving as the source of infection for human beings.

Prevalence and Associated Risk Factors of Major Gastrointestinal Parasites of Pig Slaughtered at Addis Ababa Abattoirs Enterprise, Ethiopia

“…The coproscopical examinations employed for identification of ova/oocyst include zinc sulphate flotation and sedimentation techniques which revealed the existence of parasitosis with overall prevalence of 61.8% of pigs slaughtered in the abattoir. This finding is consistent with the earlier reports of Fasil [30] in Ethiopia and Ismail HAHA [31] in Korea. However, our result is higher than the prevalence reported by Tomass [7,19,32] in Ethiopia, [33] in China and [34] in Nigeria.…”

“…The prevalence of 12.6% recorded for A. suum in this study was higher than 4.9% reported from Bishoftu, Ethiopia [19], 3.7% from Turkey [41] but lower than 54.6% reported from Bostwana [16], 17.6% from Korea [31] and 18.5% from Plateau state of Nigeria [42]. The moderately high prevalence of A. suum in the present study might be associated with farm management systems and access of free roaming of pig in the environment which facilitates ingestion of thick-shelled eggs of A. suum.…”

Prevalence of end parasites of pig at Mymensingh, Bangladesh

“…The present report is nearly similar with the findings of [3] in Western Kenya (84.2%), [18] in Kenya (83%), [19] in Western Estonia (82%) and [20] in Southwest Nigeria (80.4%). The present report is higher than [21] in Korea, [22] in Kenya, [23] in Zimbabwe, [24] in Western Iran and [25] in Aizawl who reported 73.5%, 67.8%, 58.7%, 58.3% and 37.5%, respectively. The differences in the prevalence may be due to the differences in climatic conditions, husbandry practies, breeds and inherent characteristics such as host immunity in the study regions.…”

“…infection is similar to [33] in Poland (58.5%), and [34] in Japan (40%) and highly differ from [35] in Ghana and [36] in China. The present result of Balantidium coli infection is differ from [21] in Korea (64.7%), [3] in Kenya (64%) and [37] in Danish (>57%). The differences in the prevalence may be due to the differences in husbandry practies, the techniques of sample collection, period and place of study, environmental factors and breed of animal etc.…”

Gastrointestinal parasites of swine raised in different management systems in the State of Rio de Janeiro, Brazil

“…Ismail et al (2010) studied pig rural areas of Chungcheongnam-do, Korea showed a lower frequency of Entamoeba sp. (3.7%) than those detected in the farms of Rio de Janeiro.…”
