Infection patterns of helminths in Norops brasiliensis (Squamata, Dactyloidae) from a humid forest, Northeastern Brazil and their relation with body mass, sex, host size, and season [PDF]

open access: yesHelminthologia, 2019
Climatic and ecological factors can influence the parasite load of a host. Variation in rainfall, body size, and sex of the hosts may be related to the abundance of parasites.

First light microscopy and ultrastructural description of Mesocoelium sociale (Luhe, 1901) Odhner, 1910 (Trematoda: Mesocoeliidae) in Bufo regularis from Egypt

open access: yesJournal of Basic and Applied Zoology, 2020
Background Mesocoeliidae is a common parasite of the small intestine of amphibians and reptiles. From Egypt, only Mesocoelium monas (Rudolphi C., Berolini 811 (1819)) (Freitas JF, Revista Brasiliera de Biologia 18:171-174, (1958)) was reported and ...

Population distribution of Ochoterenella digiticauda (Nematoda: Onchocercidae) and Mesocoelium monas (Digenea: Brachycoeliidae) in naturally infected Bufo marinus (Amphibia: Bufonidae) from Jamaica

open access: yesParasitology, 1985
The worm burden distributions of a macrofilarial nematode, Ochoterenella digiticauda, and a gastroenteric digenean, Mesocoelium monas, were examined in a naturally infected population of Bufo marinus from Jamaica. Both parasite species had over-dispersed distributions which were well described by the negative binomial probability model (k = 0·35 for 0.

Spermatozoon and spermiogenesis in Mesocoelium monas (Platyhelminthes:Digenea): ultrastructure and epifluorescence microscopy of labelling of tubulin and nucleus.

open access: yesFolia parasitologica, 1997
Spermiogenesis and the spermatozoon were studied in the digenean Mesocoelium monas Rudolphi, 1819 (from the toad Bufo sp. in Gabon). An ultrastructural study revealed that spermiogenesis follows the usual pattern found in digeneans, i.e. proximo-distal fusion of axonemes with a median cytoplasmic process followed by elongation. The spermatozoon has two

Helminth parasites of the African lizard Agama agama (Squamata: Agamidae), in Lagos, Nigeria

open access: yesRevista de Biología Tropical, 2007
Agama agama, the agamid rainbow lizard, has been reported to serve as transport and reservoir host to several protozoan and helminth parasites. We randomly sampled 310 specimens between May and July, 2005, at Oyingbo, Lagos, Nigeria (6°34’60’’ N-3°19’59’’
