DEMONSTRATION OF THE GENETIC SUPPORT OF THE SHEDDING PATTERN OF S-MANSONI CERCARIAE BY HYBRIDIZATION BETWEEN SCHISTOSOMES WITH EARLY AND LATE CHRONOBIOLOGICAL PATTERNS
The hybridization between schistosomes (S. mansoni) with an early and a late shedding pattern of cercariae lead to heterozygotous cercariae whose shedding pattern is characterized by 2 peaks (early and late). The genetic support of the shedding rhythm of cercariae is demonstrated and the participation of the daughter sporocyst in the chronobiological phenomenon of cercarial shedding is suggested.
