Evolutionary processes involved in the diversification of chelonian and mammal polystomatid parasites (Platyhelminthes, Monogenea, Polystomatidae) revealed by palaeoecology of their hosts.
Polystomatid flatworms are monogenean parasites that infect exclusively aquatic or semi-aquatic sarcopterygians such as the Australian lungfish, amphibians, freshwater turtles and the African common hippopotamus and their presence and evolution are indicative of early aquatic ecological habits within ancestral lineages.
Parasitic Infections of Amphibians in the Pendjari Biosphere Reserve, Benin
Investigation of parasitic infections of amphibians in the National Park, Buffer Zone, and Agricultural Zone of the Pendjari Biosphere Reserve, Benin found infection with trematodes occurred predominantly in hosts collected in the Agricultural Zone, indicating that landscape alteration, pesticide use and nutrient enrichment from fertilizers in this zone may be enhancing intermediate host populations and hence parasite prevalence.
A redescription of Polystoma africanum Szidat, 1932 (Monogenea: Polystomatidae)
It is concluded that P. africanum is exclusively parasitic in A. regularis, and that the polystomes retrieved from P. mascareniensis from Uganda and a Ptychadena sp.
Anurans as Intermediate and Paratenic Hosts of Helminth Infections in the Rainforest and Derived Savanna Biotopes of Southern Nigeria
Anurans from the rainforest and derived savanna locations in Nigeria were investigated for their role either as intermediate or paratenic hosts of helminth infections, finding Afrixalus dorsalis is a new host record for the ascaridoid nematode while the finding of the strigeoid trematode, the proteocephalid cestode larvae and acanthOcephalan cystacanths in the anurans investigated represents new geographical records.
Polystoma okomuensis n. sp. (Monogenea: Polystomatidae) from Boulenger's striped frog, Phlyctimantis boulengeri (Perret, 1986) in Nigeria
Abstract Polystoma okomuensis is described as a new species of the Polystomatidae parasitic in the urinary bladder of Boulenger's striped frog Phlyctimantis boulengeri in the Okomu National Park, Edo
Pattern of parasitic infections in anurans from a mangrove community of the Niger Delta, Nigeria
The mangrove environment at Ijala-Ikeren sustains a low diversity of amphibians which habour a low number of parasite species, whose low intensity of infection may be attributable to the parasite-hostile nature of the habitat.
Helminth Parasites of Amphibians from a Rainforest Reserve in Southwestern Nigeria
It is shown that monogeneans in Nigeria were preferentially parasites of amphibians in drier environments such as the savanna, but it is also shown that these parasites also infect amphibian in highly humid environmentssuch as the rainforest.
Polystomoides bourgati (Monogenea: Polystomatidae) Infecting Pelusios castaneus in Southern Nigeria
Pelusios spp. procured from four locations in southern Nigeria were investigated for polystomatid infection. None of the P. niger examined haboured monogeneans. Pelusios castaneus from Sapele, Ossisa
Parasitic infections of the African dwarf crocodile (Osteolaemus tetraspis) and the ornate Nile monitor (Varanus ornatus) from Nigeria
The parasitic infections of market derived Osteolaemus tetraspis and Varanus ornatus from locations in the savanna-mosaic and the rainforest of southern Nigeria were investigated and parasites recovered included members of the Pentastomida, Trematoda and Nematoda.
Diets of Hemisus mamoratus and Leptopelis hyloides (Order anura) from monoculture plantations in southern Nigeria.
The stomachs of 73 anurans, consisting of 22 Hemisus marmoratus and 51 Leptopelis hyloides from two monoculture plantations (oil palm and rubber), respectively, in Okomu-Udo, Edo State, were examined
