Abstract
Two Knots, among 88 dissected, contained the trematodeCyclocoelum mutabile. One represents the first record of this trematode from the Afrotropics. Both birds showed retardation of moult, and it is possible that such parasites have an indirect lethal effect, and that they affect breeding performance of this migrant wader with a tight annual schedule.
Zusammenfassung
Zwei von 88 sezierten Knutts enthielten den SaugwurmCyclocoelum mutabile. Einer davon stellt den Erstnachweis dieses Trematoden für die Afrotropis dar. Beide Vögel waren in ihrer Mauser verspätet. Es ist möglich, daß die Parasiten indirekt tödliche Auswirkungen haben und den Brutverlauf des Knutts beeinflussen, dessen Jahreszyklus sehr gedrängt ist.
