Age- and sex-based variation in helminth infection of helmeted guineafowl (Numida meleagris) with comments on Swainson’s spurfowl (Pternistis swainsonii) and Orange River francolin (Scleroptila levaillantoides)Davies, OR, Junker, K, Jansen, R, Crowe, TM, Boomker, J 20 August 2008 (has links)
Gastrointestinal tracts from 48 helmeted guineafowl (Numida meleagris), five Swainson’s
spurfowl (Pternistis swainsonii) and a single Orange River francolin (Scleroptila
levaillantoides) were examined for helminth parasites. Twelve species of helminths were
found in helmeted guineafowl, comprising six nematodes, five cestodes and a single
acanthocephalan.Six species of nematodes were recovered fromSwainson’s spurfowl and a
single nematode was recovered from the Orange River francolin. First-year guineafowl had
more than twice the intensity of infection than did adult guineafowl, particularly regarding
the acanthocephalan Mediorhynchus gallinarum, the caecal nematodes Subulura dentigera
and S. suctoria, and the cestodes Octopetalum numida, Hymenolepis cantaniana and Numidella numida. Female guineafowl had significantly higher intensities of infection than males, especially concerning M. gallinarum, S. dentigera and N. numida and the nematode
Gongylonema congolense. The recovery of the cestode Retinometra sp. from helmeted guineafowl constitutes a new host-parasite record.
