A paleoparasitological study was carried out on 2 lead coffins recovered from the Roman site of Jaunay-Clan (near Poitiers, France). For the first time, this particular type of burial gave positive parasitological results, and eggs of the whipworm Trichuris trichiura were identified in 1 individual. In the present case, thanatomorphose associated with funerary practices may explain the scarcity of the recovered eggs. However, human whipworm has now been observed in 9 individuals dated to the Roman period. The very high frequency of Trichuris sp. eggs in Roman archaeological sites (up to 80%) suggests that fecal peril, hygiene, and waste management were problematic during this period. Finally, due to the fact that very few analyses have been conducted on human bodies dated to the Roman period, more analyses must be performed in the future to provide further information about diseases in the Roman world.

We analyzed 320 clinical samples of parasitic infections submitted to the Department of Environmental Biology and Medical Parasitology, Hanyang University from January 2004 to June 2011. They consisted of 211 nematode infections, 64 trematode or cestode infections, 32 protozoan infections, and 13 infections with arthropods. The nematode infections included 67 cases of trichuriasis, 62 of anisakiasis (Anisakis sp. and Pseudoterranova decipiens), 40 of enterobiasis, and 24 of ascariasis, as well as other infections including strongyloidiasis, thelaziasis, loiasis, and hookworm infecions. Among the cestode or trematode infections, we observed 27 cases of diphyllobothriasis, 14 of sparganosis, 9 of clonorchiasis, and 5 of paragonimiasis together with a few cases of taeniasis saginata, cysticercosis cellulosae, hymenolepiasis, and echinostomiasis. The protozoan infections included 14 cases of malaria, 4 of cryptosporidiosis, and 3 of trichomoniasis, in addition to infections with Entamoeba histolytica, Entamoeba dispar, Entamoeba coli, Endolimax nana, Giardia lamblia, and Toxoplasma gondii. Among the arthropods, we detected 6 cases of Ixodes sp., 5 of Phthirus pubis, 1 of Sarcoptes scabiei, and 1 of fly larva. The results revealed that trichuriasis, anisakiasis, enterobiasis, and diphyllobothriasis were the most frequently found parasitosis among the clinical samples.

Trichuris trichiura, commonly referred to as a whipworm, has a worldwide distribution, particularly among countries with warm, humid climates. In Korea, trichuriasis was a highly prevalent soil-transmitted helminthiasis until the 1970s. However, the nationwide prevalence decreased to 0.02% in 2004 as a result of national control activities and improvement in the socioeconomic status of Koreans. Most infected individuals have no distinct symptoms, if lightly infected. The diagnosis is typically confirmed by detection of T. trichiura eggs on examination of a stool sample; few reports have described detection of the parasite during colonoscopy. Recently, we managed 4 patients with trichuriasis who were diagnosed by detection of the parasite on colonoscopy, and we reviewed the literature on the colonoscopic diagnosis of T. trichiura in Korea. We suggest that colonoscopy might be a useful diagnostic tool, especially when infected by only a few male worms with no eggs in the stool.

Soil-transmitted helminth (STH) infections are still a considerable challenge in Myanmar. We undertook a control program for STH infections (especially Trichuris trichiura) among schoolchildren in Myanmar using mass drug administration (MDA) and health education. Around 1,700 schoolchildren from 15 primary schools in 3 suburban districts (Shwe Pyi Thar, Twantay, and Kyauktan) of the Yangon Region were subjected in this study during 2017-2019. All of the schoolchildren in each school were orally administered albendazole (400 mg in a single dose) 2, 3, and 4 times a year in 2017, 2018, and 2019, respectively. The results revealed that the egg positive rate of any intestinal helminths (including STH) was reduced from 37.6% (649/1,724) in 2017 to 22.8% (352/1,542) in 2019. The egg positive rate of Ascaris lumbricoides was decreased remarkably from 23.3% (402/1,724) in 2017 to 3.6% (56/1,542) in 2019. However, that of T. trichiura was only slightly reduced from 26.9% (464/1,724) in 2017 to 20.2% (312/1,542) in 2019. The intensity of infection with A. lumbricoides and T. trichiura was both more or less reduced, and the proportion of light infection cases with A. lumbricoides and T. trichiura increased from 35.6% in 2017 to 64.3% in 2019 and from 70.3% in 2017 to 81.7% in 2019, respectively. The results indicated that repeated MDAs (2-4 times a year for 3 years) using albendazole on schoolchildren in Myanmar failed to control T. trichiura infection. For a successful control of trichuriasis in Myanmar, new MDA strategies, using a modified albendazole regimen (multiple daily doses for 2 or 3 days) or an alternative anthelmintic drug, such as oxantel pamoate, is strongly recommended.

편층증의 개인치료와 집단관리에 있어서 메벤다졸의 유용성 및 효과를 측정하였다. 메벤다졸(100∼1,200mg) 투약 3주후 430명에 있어서의 치료효과는 15.0∼64.0% 및 24.6∼95.2%의 치유율 및 충란감소율을 보여 대체로 만족스럽지 못한 결과이었으나 메벤다졸의 총 투여량이 높으면 높을수록 치유율 및 충란감소율도 높아지는 것이 관찰되었다. 일정간격 반복투여(600mg용량)에 의한 집단관리를 주민(4개군, 총 551명)의 편충란양성율은 3개월간격(3일 분복군) 투여 군에서 가장 현저한 감소추세를 보여 관리시작후 1년만에 40.0%에서 5.6%로 저하되었고, 3개월 간격(단희 또는 2회 분복군), 6개월, 12개월군 및 대조군에서는 감소추세가 완만하거나 거의 관찰되지 않았다. 이상의 결과로 보아, 메벤다졸은 편충의 개인치료에는 그다지 우수한 결과를 나타내지 않았으나, 3개월간격으로 반복투여하면 집단관리에는 유효한 약제가 될 수 있을 것으로 생각되었다.

The current status and future prospects of parasitic infections in Korea is briefly reviewed. Soil-transmitted helminth infections including ascariasis, trichuriasis, and hookworm infections decreased remarkably. owing to the national control activities excuted by the Korea Association of Health Promotion(formerly Korea Association of parasite Eradication) using mass heath education. Important recent trends include reemergence of vivax malaria since 1993, persistence of food-borne trematode infections including clonorchiasis and intestinal trematode infections, increased detection of zoonotic parasitosis, close-up of infection with opportunistic parasites including cryptosporidiosis, toxoplasmosis, and pneumosytosis, increase of imported tropical infectious disease, appearance of new parasitic disease such as gymnophalloidiasis, and increase of accidental infections with free-living amoebae. These trends represent greatly changed overall patterns of parasitic infections in Korea.

This study was perfomed to examine the distribution of causative agent of piglets diarrhea in eastern Chonnam province from February 1994 to March 1995. The causative agents of diarrhea were examined by bacterial culture test, parasitological test and serological test against PED, TGE and Rota. The 35 isolated E. coli were tested for antibiotic sensitivity. The results obtained were as follows. 1. The incidence of 81 piglets with diarrhea was most prevalent as 39.5% in the age of 2 to 4 weeks, compare to 34.6% in the age of 5 to 8 weeks and 16.0% under 1 weeks and 9.9 % in the age of 9 to 11 weeks after birth. 2. The incidence of 81 piglets diarrhea showed bacterial diarrhea(75.3%), viral diarrhea (35.8%) and parasitological diarrhea(18.5%). When compared the isolation frequency of each etiological agent, enteropathogenic E. coli was most prevalent as 55.5% in bacterial diarrhea, rotavlrus enteritis as 18.5% in viral diarrhea and trichuriasis as 13.6% in parasitological diarrhea. 3. The complicated infection of piglets was most prevalent as 41.7% in rotavirus enteritis with enteropathogenic E coli in 24 complicated piglets diarrhea. 4. In antibiotic sensitivity test, isolates showed moderatly resistance to Tobramycin, Amikacin, Imipenem, Trimethoprim/Sulfamethoxazole, Gentamicin, Ampicillin but sensitivty to Ticarcillin/K. The 30 E. coli isolate showed multiple drug resistances in 3 different antibiotics.

Soil-transmitted helminthiases (STH) are now no longer public health problems in the Republic of Korea (South Korea), but their status are unavailable in the residents of North Korea (NK) despite the expectation of large scale traffic and future reunification of the Korean Peninsula. A total of 20 female refugees from NK who had been admitted to the Division of Gastroenterology, Dankook University Hospital, were subjected in this study. Among them, 15 refugees were examined by the colonoscopy and 10 ones were examined with the stool examination (formalin-ether sedimentation). Both diagnostic methods were commonly adopted in 5 patients. Eggs of Trichuris trichiura were detected in 7 out of 10 refugees in the stool examination. In the colonoscopy, T. trichiura worms were found in 6 (40.0%) out of 15 refugees. Total 9 (45.0%) peoples were confirmed to be infected with human whipworms. Additionally, 1 case of clonorchiasis was diagnosed in the stool examination and a worm of Ascaris lumbricoides was discovered from a trichuriasis case. These findings suggested that STH is highly prevalent in NO, in which living conditions are not so good in the aspect of general hygiene and medical care.

We analyzed parasitic diseases diagnosed by tissue biopsy specimens at KyungHee Medical Center (KMC) from 1984 to 2005. The total number of parasite infection cases was 150 (0.07%) out of the total 211,859 biopsy specimens submitted for histopathological examinations. They consisted of 62 cysticercosis, 23 sparganosis, 16 paragonimiasis, 15 amebiasis, 11 anisakiasis, 11 clonorchiasis, 3 ascariasis, 2 scabies, 2 enterobiasis, 2 trichuriasis, 1 leishmaniasis, 1 taeniasis, and 1 thelaziasis. Out of 62 cysticercosis cases, 55 were detected in subcutaneous tissues or the central nerve system. Eighteen out of 23 sparganosis cases were involved in muscular and subcutaneous tissues. In most anisakiasis cases, the involved organ was the stomach. The lung and the pleura were the most common site of paragonimiasis. The incidence of parasitic diseases during the first 5 years (1984-1988) was the highest of all observed periods. After 1989, similar incidences were shown throughout the period. Whereas cysticercosis was diagnosed in 34 cases during 1984-1988, no case has been diagnosed since 2000. In the case of sparganosis, the chronological incidence was almost uniform throughout the period 1984-2005. Paragonimiasis showed a similar tendency to cysticercosis. In gender and age distribution of parasitic diseases, men showed higher incidence rates than females, and the age groups of the 40s or older indicated higher infection frequencies than other age groups. Therefore, these results are a significant report to appear the tendency of human parasitic disease diagnosed by tissue biopsy in association with parasitosis at KMC in Seoul.
