The parasite infects cells of the gut epithelium and initiates sporogony
, which ends with the formation of a sporophorous vesicle (= SV), a spherical cluster of spores, surrounded by a membrane, inside the host cell.
Average mean temperature of 20[degrees]C prevails throughout the year and relative humidity (RH) of [greater than or equal to] 60% was observed from June to October which is suitable for sporogony
is hindered or prevented completely by oxygen deficiency, low environmental temperatures, or desiccation.
HOBO data loggers (Onset Computer Corporation, Bourne, MA, USA), which are devices for measuring temperature and humidity, were placed inside all experimental houses where the duration of sporogony
