Detection of schistosome infection in the invasive snail Melanoides tuberculata (Gastropoda: Thiaridae) by polymerase chain reaction from Plateau State, Nigeria: a novel turning point in disease epidemiology and control?

BACKGROUND
Melanoides tuberculata is a freshwater snail that serves as an intermediate host for 11 parasitic flukes. This study was conducted with the aim of identifying and screening the snail intermediate hosts in the study site for schistosomiasis using the molecular technique.


METHODS
DNA was extracted from the snails by the hexadecyl trimethyl ammonium bromide method and the Dra1 primer was used to amplify the Dra1 repeated sequence of Schistosoma haematobium.


RESULTS
The presence of schistosome DNA in M. tuberculata by polymerase chain reaction was confirmed.


CONCLUSIONS
Our findings show that M. tuberculata is a potential intermediate host of schistosomes.
