High prevalence of large trematode eggs in schoolchildren in Cambodia

Large trematode eggs (LTE) resembling Fasciola spp. eggs were reportedly found in the stools of schoolchildren in Kandal province, Cambodia. This study aimed to assess the prevalence of LTE in the stools of children attending the affected school, identify potential risk factors for infection and ascertain the trematode species. We performed a cross-sectional study involving an in-depth questionnaire administered to schoolchildren at the affected school, and examined cattle droppings in the surrounding area and the livers of slaughtered cattle. Three stool samples were examined per child, using KatoKatz and formalin-ether concentration techniques. In addition, blood serum ELISA and coprological PCR was conducted for species clarification. Cattle droppings were examined by cup sedimentation and coprological ELISA. LTE were observed in the stools of 228 schoolchildren (46.5%). Two blood serum samples from schoolchildren were positive for Fasciola hepatica in a first ELISA but were negative in a confirmation immunofluorescence antibody test. Out of 221 PCR samples, only one tested positive for transmission from cattle to human is possible and public health services need to be alerted accordingly.3

“…Studies from other countries, namely, Philippines, Cambodia and Turkey, have reported a higher prevalence of intestinal parasites among school children. [10][11][12] This could be attributed to the different geographical location and time of the survey, i.e., summer (January to June), which is a low transmission season. Also, the direct microscopic examination method used for detection of parasites has a low rate of parasite 3) 34 (1.6) n a n a Necator…”

This study was conducted to estimate the prevalence of intestinal parasitic infestations among school children in Kaski District of Western Nepal. A total of 2091 stool samples were collected from school children selected from 11 rural and eight urban schools. The stool samples were examined for evidence of parasitic infections by direct microscopic examination. Prevalence of intestinal parasites was 21.3%. There was a significant difference in prevalence between urban (18.7%) and rural (24.1%) school samples. Giardia lamblia (13.2%), Ascaris lumbricoides (2.1%) and Entamoeba histolytica (1.7%) were the commonest parasites isolated. The results indicate that intestinal parasitic infestation among school children in the study area is mainly water-borne. The burden of parasitic infestations among the school children, coupled with the poor sanitary conditions in the schools, should be regarded as an issue of public health priority. This strongly supports the need for school health programmes that will involve periodic deworming, health education and improvement of school sanitation.

“…Recent studies in Cambodia have reported that the proportion of IPIs-positive children ranges between 19.1% and 70.2%, and a child infected with multiple parasites is common. 2-4 , 6 , [10][11][12] In this study, the most common parasites in schoolchildren were G. intestinalis (31.5%) and E. histolytica/dispar (17.5%). However, E. histolytica and E. dispar are not distinct under a microscope.…”

“…Almost all these studies have focused on Ascaris lumbricoides (2-40%), Hook worm (3.4-65%), Trichuris trichiura (0.4-17.3%), and Strongyloides stercoralis (0.4-31.5%) in communities and hospitals. [6][7][8][9][10][11][12][13] The Cambodian Ministry of Health has implemented national deworming programs. However, mass treatment has only focused on the most common parasites, such as A. lumbricoides, Hook worm, and T. trichiura.…”

Abstract. Most intestinal parasitic infections (IPIs), commonly endemic in tropical resource-poor developing countries, are neglected tropical diseases. Parasitic infections and malnutrition are most commonly found in children. We determined the prevalence of IPIs and the risk factors in Battambang Province, northwestern Cambodia, from August to September 2015. This study collected 308 valid questionnaires and specimens from Dontri (173, 56.2%) and Kon Kaêk (135, 43.8%) primary schools. All stool samples were examined using Chang's Feces Examination Apparatus through the merthiolate-iodine-formaldehyde technique. Headache (259, 84.1%), recurrent cough (249, 80.8%), and abdominal pain (235, 76.3%) were the most common symptoms as detected from questionnaire investigation. A total of 155 students were positive for any parasite type; a single parasite type was observed in 97 students (31.5%), two types in 40 students (13.0%), three types in 14 students (4.6%), and four types in four students (1.3%). Nine gastrointestinal parasite species (three helminths and six protozoa) were identified in the stool samples. The most common parasites in schoolchildren were Giardia intestinalis (31.5%) and Entamoeba histolytica/dispar (17.5%). This is the first IPIs study, and more than half of the schoolchildren were infected with parasite species in Moung Russey District of Battambang Province. We found nine parasite species, including helminths and protozoa, and pathogenic protozoa were the main source of IPIs. Improving the detection method, sanitation facilities, and personal hygiene as well as utilizing combined drugs are all important measures to greatly reduce IPIs in Cambodian schoolchildren.
