Figure 1From: Simultaneous infection of Schistosoma mansoni and S. rodhaini in Biomphalaria glabrata: impact on chronobiology and cercarial behaviourChronobiology of cercarial emergence. Chronobiology of S. mansoni and S. rodhaini cercarial emergence from snails individually infected with each species (A and B), snails doubly exposed at a dose of 3 miracidia of each species but only patently infected with S. mansoni (C), doubly exposed at a dose of 6 miracidia of each species but with only single patent infections of S. mansoni or S. rodhaini (D) and snails doubly exposed to a dose of 6 miracidia of each species and doubly infected (E) over a 24 hr period (+- SE), ( . . . . = transition from light to dark.)Back to article page
