Abstract/Summary

Two hundred ten lymnaeid snails identified as Lymnaea quadrasi were collected each from Sta. Maria River, Barangay Catmon, Sta. Maria, Bulacan and at Sunken Garden Lagoon, University of the Philippines, Diliman. Snails were examined for the presence of trematode larvae and Chaetogaster limnaei infestation. Results show that length of snail > 1.0cm exhibited a positive relationship with trematode infection and C. limnaei infestation. Prevalence of trematode infection in L. quadrasi collected from Sta. Maria River and Sunken Garden Lagoon were 50.48% and 68.60%, respectively. Trematode larvae such as typical distome, microcercous, metacercariae and a precocious adult-looking like trematode were observed. Chaetogaster limnaei was noted in 17 *8.10%) of the L. quadrasi collected from Sta. Maria River. Snails from Sunken Garden Lagoon were free of C. limnaei infestation, instead insect larvae belonging to Genus Chironomus were recovered.
