Abstract:
Human infection with 〈 i 〉 Echinostoma aegyptica 〈 /i 〉 Khalil and Abaza, 1924 (Trematoda: Echinostomatidae) is extremely rare. In this study, we confirmed 〈 i 〉 E. aegyptica 〈 /i 〉 infection in 5 riparian residents living along the Mekong River in Savannakhet Province, Lao PDR. The patients revealed eggs of 〈 i 〉 Opisthorchis viverrini 〈 /i 〉 /minute intestinal flukes, echinostomes, and other parasites in fecal examinations using the Kato-Katz technique. Following treatment with praziquantel 30-40 mg/kg and pyrantel pamoate 10-15 mg/kg in a single dose and purging with magnesium salts, adult specimens of various helminth species were collected. Among the trematodes, echinostome flukes of 4.5-7.6 mm in length (n = 134; av. 22.3 specimens per case) were of taxonomic interest and subjected in this study. The flukes were morphologically characterized by having total 43-45 collar spines arranged in 2 alternating rows (corner spines usually 5 on each side) and compatible with previous descriptions of 〈 i 〉 E. aegyptica 〈 /i 〉 . The patients were mixed-infected with other helminths, so specific clinical manifestations due to this echinostome fluke were difficult to determine. The present paper describes for the first time human 〈 i 〉 E. aegyptica 〈 /i 〉 infections in Lao PDR. This is the second report of human infection (2nd-6th cases) with 〈 i 〉 E. aegyptica 〈 /i 〉 in the world following the first one from China.
