Three species of nematodes from the Camallanidae that are known to infect Xenopus laevis Daudin (Anura: Pipidae) were
collected from several localities across South Africa. New data on morphology, partial 28S and cox1 genes, infection levels and distribution
are presented herein. The most common species, Batrachocamallanus slomei Southwell et Kirsh...
Four species of previously known nematodes from the family Camallanidae were found from different hosts in South Africa: Batrachocamallanus xenopodis from the frog Xenopus muelleri, Paracamallanus cyathopharynx and Procamallanus pseudolaeviconchus from the catfish Clarias gariepinus and Spirocamallanus daleneae from the catfish Synodontis zambezens...
Anuran filarial nematodes are restricted to two comparatively small subfamilies (Icosiellinae and Waltonellinae) of the filariae that currently comprise six genera and 41 recognised species. However, the life histories of only five anuran filarial nematodes, proposed as an ancestral group based on molecular phylogenetic studies, have been elucidate...
The effect of invasive species on local parasite dynamics is often overlooked. The African Clawed Frog Xenopus laevis (Daudin, 1802) (Anura: Pipidae) is a global invader, with established populations on four continents and is a domestic exotic in southern Africa. Despite a century of parasitological surveys, the current study reports seven previous...
Cosmocercid nematodes have been documented with much criticism due to the numerous inaccurate descriptions, redescriptions and synonymisation of found species. This is due to indistinguishable characters of females and the lack of male specimens found. Consequently, the species C. ornata is the most commonly found species worldwide and the only spe...
This study investigated the helminths of the mixed invasive population of Darevskia armeniaca and D. dahli, collected during two field trips in Denyshy, Zhytomyr region, Ukraine, in 2023. In total, 67 adult lizards (35 D. armeniaca and 32 D. dahli) were examined. Molecular and morphological approaches were used to identify the parasites. The analys...
Two new species of lung-dwelling nematodes are described from North American frogs: Rhabdias aurorae n. sp. from Rana aurora and Rhabdias conni n. sp. from Rana clamitans and Rana catesbeiana from Arkansas; the latter species was also found in Oklahoma and Georgia. Rhabdias aurorae n. sp. differs from other Nearctic congeners in the combination of...
Background
Only a few comprehensive studies have been carried out on parasites in amphibians and reptiles in Ukraine. This has resulted in identifying over 100 helminth species across these vertebrate groups. However, most of the studies were performed in the 20th century and the taxonomy of many parasites and their hosts has changed ever since, in...
Nematodes of the genus Cosmocerca are commonly found in various amphibians in South Africa and in most cases are identified as C. ornata. However, after detailed morphological studies and molecular approaches, three new species of the genus were recently described from three different frogs in South Africa. In present study, we describe another new...
У результаті попередніх досліджень гельмінтофауни Ржищівської МОТГ було виявлено у 2 фонових видів амфібій (групи бурих жаб (Ranidae)) 4 види гельмінтів. З них більшість представляли нематоди родів Rhabdias (29,82 %),
Oxysomatium (64,91 %) та Oswaldocruzia (1,75 %). Також було зареєстровано два випадки виявлення моногеней Polystoma (3,51 %). Загаль...
Icosiella neglecta (Diesing, 1851) is a filarial nematode infecting anuran amphibians in the western Palaearctic. In the present survey, we found I. neglecta in 27 out of 28 localities in eight regions of Ukraine. In those localities, 56.5 % of sampled green frogs (Pelophylax esculentus complex) were infected. The infection prevalence was similar i...
Three new species of lung-dwelling nematodes are described from the frogs Ptychadena anchietae (Bocage), P. oxyrhynchus (Smith), and P. uzungwensis (Loveridge) in southern Africa. All three species are medium-sized species of Rhabdias Stiles et Hassall, 1905, with the thick-walled buccal capsules measuring 11–13 μm × 6–11 μm, consisting of longer a...
Serpentirhabdias mamlambo n. sp. is described from the lung of the herald snake, Crotaphopeltis hotamboeia (Laurenti) in KwaZulu-Natal Province, South Africa. The new species is characterised by the small lips, the absence of the buccal capsule, the large excretory glands (1.5–2.3 times longer than the oesophagus), and the numerous eggs in uteri. S...
IntroductionPseudocapillaria (Ichthyocapillaria) bumpi n. sp. (Nematoda: Capillariidae) is described from specimens infecting the digestive tract of the West African lungfish, Protopterus annectens (Owen) (Lepidosireniformes: Protopteridae).Methods
Nematodes were collected in Karingani Game Reserve, Southern Mozambique and studied using light micro...
IntroductionThe nematode Spiroxys ankarafantsika was described parasitising freshwater turtles Pelusios castanoides and Pelomedusa subrufra from Madagascar. During parasitological surveys at different localities in Mozambique and South Africa the species was recovered from the digestive tract of Pelusios sinuatus, P. subniger and P. castanoides.Met...
The genus Neofoleyellides was recently erected for a single species, Neofoleyellides boerewors from bufonid hosts in South Africa. In present study, we discovered two undescribed species of Neofoleyellides, namely N. steyni n. sp. and N. martini n. sp. parasitising frogs Amietia delalandii and Leptopelis natalensis, respectively. Both species diffe...
Nematodes of the genus Amphibiophilus Skrjabin, 1916 are a small group of parasites restricted to pyxicephalid frogs in southern Africa. In the present study, the new species A. bialatus parasitising the clicking stream frog Strongylopus grayii (Smith) as well as two forms parasitising the common river frog Amietia delalandii (Duméril & Bibron) fro...
Rhabdias delangei n. sp. (Nematoda: Rhabdiasidae) is described from the lungs of the clicking stream frog Strongylopus grayii (Smith) in the Western Cape Province of South Africa. The new species is characterised by the nerve-ring being located just posterior to the mid-length of the oesophagus, a pre-equatorial vulva, as well as a thin-walled and...
Een van die grootste groepe rondewurms wat diere parasiteer behoort aan die familie Camallanidae. Nematode van hierdie groep kom wêreldwyd voor en bewoon die spysverteringskanale van mariene en varswatervisse, amfibieë en reptiele (hoofsaaklik varswaterskilpaaie) (Yeh 1960; Baker 1987).
The genus Serpinema was erected from the genus Camallanus to include species parasitising freshwater turtles. Following this, the taxonomic status of Serpinema was challenged by different authors considering it as a subgenus or junior synonym of Camallanus. Several specimens of these nematodes were retrieved from the spot-legged wood turtle Rhinocl...
Rhabdias picardiae previously known from the Guttural Toad, Sclerophrys gutturalis (Bufonidae) is described from a new host, Delaland’s River Frog, Amietia delalandii (Pyxicephalidae). The species identification is confirmed by analysis of the COI gene sequence and morphological comparison with the original description. Morphological details of api...
Four species of the genus Amphibiophilus Skrjabin, 1916 from pyxycephalid frogs in southern and central Africa are currently recognised as valid. Several specimens of Amphibiophilus were found in material from the common river frog, Amietia delalandii (Duméril & Bibron) (Amphibia: Pyxicephalidae), collected in Potchefstroom (North-West Province, So...
Nematodes comprise the biggest component (over 70 %) in helminth communities of
African amphibians; however, there are only 24 species reported from fewer than 40 species of amphibians in South Africa. In the helminthological material collected from
103 specimens of Amietophrynus gutturalis (Power, 1927), 26 Amietia delalandii (Boulenger, 1895) and...
Two new species, Oswaldocruzia lisnykiensis sp. n. and Oswaldocruzia lacertica sp. n., are described from Anguis fragilis L. (Reptilia: Anquidae) and Lacerta agilis L. (Reptilia: Lacertidae) respectively. Both species belong to the Palaearctic group of species which have spicules divided in three main branches (blade, fork and shoe) with fork divis...
Sixteen specimens of Oswaldocruzia (Nematoda, Molineidae) were found in the material from Zootoca vivipara Lichtenshtein, 1823 collected in Ukraine. The nematodes were identified as O. skrjabini Travassos, 1937 due to the presence of well-developed cervical alae and the host species. Based on the specimens examined, an amended description of the sp...
The species composition of amphibians of national park “Piryatinsky" was studying during the annual ecological expeditions in 2007 – 2013.
