Abstract
OBJECTIVES:
Freshwater snails, as first intermediate hosts of trematodes, can cause health hazards in animals and humans. Recently, WHO has included Iran among six countries known to have a serious problem with fascioliasis. In addition, Cercarial dermatitis is a job-related disease that is seen often in paddy workers and swimmers of Iran particularly in the Mazandaran province. In our country, many studies have been conducted to survey larval trematodes in freshwater snails. However, to the best of our knowledge, there are no comprehensive data regarding the infection of gastropods. Therefore, the aim of the present study was to estimate the types and prevalence of cercarial infection in snails in Iran.
METHODS:
Electronic English and Persian language databases were searched to identify 24 published articles reporting the prevalence of trematode infections in snails in provinces of Iran. Snails of nine different species from six families were collected in the provinces.
RESULTS:
A total of 4.4 % of gastropods were infected with larval stages of the trematodes. According to the studies reviewed in this meta-analysis‚ the highest infection prevalence was found for Radix auricularia (9.9 %). Twelve larval species of trematodes were identified and the highest prevalence of cercaria found for Echinostomatidae cercariae (4.3 %). Among the provinces explored, West Azerbaijan had the highest prevalence of infected snails, (16.9 %).
CONCLUSIONS:
The presence of trematodes in snails could pose a serious health problem in Iran. Thus, further studies are necessary to identify these infections in other provinces.
