Most previous works on release of cercariae by freshwater snails
have been mainly restricted to America, Asia and Europe with little
reports from other regions especially Africa. In Nigeria, especially
Borno State, there is still gap in knowledge particularly on the pattern
of cercarial shedding of trematodes within the region. The role of snails
in the epidemiology of important infections such as schistosomiasis,
fascioliasis, paragonimiasis, and clonorchiasis deserves attention.
Therefore, the current study was aimed at determining the distribution of
snail(s) of possible medical and veterinary importance and the cercarial
release pattern in Borno State.
