## TL;DR

A study in Cambodia found that many schoolchildren and adults are infected with Echinostoma mekongi, likely from eating snails.

## Contribution

The study confirms snail consumption as the source of Echinostoma mekongi infection using both morphological and molecular methods.

## Key findings

- Echinostoma mekongi infection was found in 13.9% of participants in Kandal Province.
- Consumption of Pila sp. snails was identified as the source of infection.
- Molecular analysis confirmed the infection source using cox1 and nd1 genes.

## Abstract

A high prevalence of Echinostoma mekongi infection (13.9%; 260/1,876) was found among schoolchildren and adults in Kandal Province, Cambodia, by fecal examination, worm expulsion, and molecular analysis of cox1 and nd1 genes. The source of infection was consumption of Pila sp. snails, a finding confirmed morphologically and molecularly.

## Linked entities

- **Genes:** COX1 (cytochrome c oxidase subunit I) [NCBI Gene 4512], ND1 (NADH dehydrogenase subunit 1) [NCBI Gene 4535]
