Gastrointestinal Helminthic Infection among the Population in Northern Thailand.

Purpose: Gastrointestinal (GI) helminthic infections pose substantial public health threat, particularly in northern Thailand, with a heightened concern in Nan province. This study aims to evaluate the prevalence of GI helminthic infections in Nan province and identify associated risk factors in local population.

Methods: A cross-sectional survey was conducted in 2022.

Anthelmintic activity and pathophysiological effect of anthelmintic drugs against carcinogenic liver fluke, Opisthorchis viverrini.

Human liver fluke, Opisthorchis viverrini poses a significant risk for development of cholangiocarcinoma (CCA) in Thailand, primarily attributed to consumption of undercooked cyprinoid fishes. The current use of anthelmintic drug treatment such as praziquantel (PZQ), as the main therapeutic agent against O. viverrini.

Oral parasitic protozoan Entamoeba gingivalis in periodontal disease patients, northeastern Thailand.

Entamoeba gingivalis is present in the oral cavity of humans and is associated with periodontal disease. Consequently, this study aimed to comprehensively investigate the E. gingivalis infection and the associated risk factors among individuals suffering from periodontal conditions.

Molecular identification of Opisthorchis viverrini among the northeastern Cambodian population by internal transcribed spacer 2 based polymerase chain reaction.

The southeast Asian fluke Opisthorchis viverrini remains endemic, particularly in Thailand, Lao PDR, Cambodia, Vietnam, and Myanmar. However, there is a lack of data on the prevalence of liver fluke infection in Kratie Province in northeastern Cambodia. The present study aimed to detect O.

Molecular detection of oral Trichomonas tenax in periodontal disease patients by polymerase chain reaction -based 18S rRNA gene.

Trichomonas tenax, an oral flagellated protozoon found in humans, potentially associated with the inflammation of periodontal tissues and decreased immunity that causes the tissue damage and tooth loss from chronic infection. Currently, there is a lack of data regarding the prevalence of T. tenax infection in Thailand.

Intestinal parasitic infections and risk factors among the population in Cambodia.

Many species of helminths and protozoa caused intestinal parasitic infections (IPIs). It belongs to neglected tropical diseases (NTDs) and remains a major public health problem in several Southeast Asian countries. The present study aimed to investigate the prevalence of IPIs and associated risk factors among the population in Kratie Province in northeastern Cambodia and Phnom Penh is the capital that locates in southern Cambodia.

Prevalence and intensity of helminths among inhabitants of the Chi River and Lahanna water reservoir areas of Northeastern Thailand.

Helminth infections (HIs) are an important public health problem in tropical countries, and the associated problems have been neglected in rural areas of Thailand. Therefore, this study reports the prevalence and intensity of HIs among inhabitants of the Khon Sawan district, Chaiyaphum province, and Kaeng Samnam Nang district, Nakhon Ratchasima province, which are located near the Chi River and Lahanna water reservoir, northeastern Thailand. A cross-sectional descriptive study was conducted between July 31, 2018, and June 30, 2019, among rural villagers from 40 rural villages in 4 subdistricts.

The prevalence of intestinal helminth infection in rural subdistricts of northeastern Thailand.

This study aimed to determine the prevalence and intensity of intestinal helminth infections (IHIs) among rural villagers in Waeng Noi district, Khon Kaen Province, northeastern Thailand. A cross-sectional study was conducted between March 1 and July 30, 2018, among rural villagers from 30 rural villages in 2 subdistricts. The participants were selected from the village enrollment list after proportional allocation of the total sample size.

Effects of aestivation on survival of Bithynia siamensis goniomphalos snails and the infection of Opisthorchis viverrini in the irrigation area of wet- and dry-season rice paddy.

The snail Bithynia siamensis goniomphalos acts as the first intermediate host of the human liver fluke, Opisthorchis viverrini, a major cause of cholangiocarcinoma in Northeast Thailand. In this study, we investigated host-parasite interactions in wet- and dry-season rice paddy plantation. The snails that aestivated through 4-month-dried period after rice harvest had average mortality rate of 36.

Animation as Supplementary Learning Material About Carcinogenic Liver Fluke in Classes for Primary Schoolchildren.

Carcinogenic liver fluke is still an issue of great concern in some countries of Southeast Asia, particularly in Thailand, Cambodia, the Lao People's Democratic Republic, and Vietnam. The infection, caused by Opisthorchis viverrini, is associated to cholangiocarcinoma and is endemic among human populations for whom raw fish is frequently consumed. Prevention and health education are required.

Effects of albendazole, artesunate, praziquantel and miltefosine, on Opisthorchis viverrini cercariae and mature metacercariae.

Objective: To explore larvicidal effects of anthelmintic drugs on Opisthorchis viverrini (O. viverrini) for alternative approach to interrupting its cycle for developing a field-based control program.

Methods: The larvicidal activities of albendazole (Al), artesunate (Ar), praziquantel (Pzq) and miltefosine (Mf) on O.
