“…sp., species of Cardiofilaria Strom, 1937, Aproctella Cram, 1931, Rumenfilaria Lankester & Snider, 1982 and Madathamugadia Chabaud, Anderson & Brygoo, 1959 (Splendidofilariinae) have subequal spicules [2, 3, 57]. Cardiofilaria and Aproctella can be further distinguished from the new genus by caudal papillae that are arranged in a circle or semi-circle around the cloaca of males (sometimes irregularly distributed in Cardiofilaria ), and members of both genera are found in the body cavity of birds [1, 2, 58–60].

BackgroundThe filarial nematodes Wuchereria bancrofti (Cobbold, 1877), Brugia malayi (Brug, 1927) and B. timori Partono, Purnomo, Dennis, Atmosoedjono, Oemijati & Cross, 1977 cause lymphatic diseases in humans in the tropics, while B. pahangi (Buckley & Edeson, 1956) infects carnivores and causes zoonotic diseases in humans in Malaysia. Wuchereria bancrofti, W. kalimantani Palmieri, Pulnomo, Dennis & Marwoto, 1980 and six out of ten Brugia spp. have been described from Australia, Southeast Asia, Sri Lanka and India. However, the origin and evolution of the species in the Wuchereria-Brugia clade remain unclear. While investigating the diversity of filarial parasites in Malaysia, we discovered an undescribed species in the common treeshrew Tupaia glis Diard & Duvaucel (Mammalia: Scandentia).MethodsWe examined 81 common treeshrews from 14 areas in nine states and the Federal Territory of Peninsular Malaysia for filarial parasites. Once any filariae that were found had been isolated, we examined their morphological characteristics and determined the partial sequences of their mitochondrial cytochrome c oxidase subunit 1 (cox1) and 12S rRNA genes. Polymerase chain reaction (PCR) products of the internal transcribed spacer 1 (ITS1) region were then cloned into the pGEM-T vector, and the recombinant plasmids were used as templates for sequencing.Results Malayfilaria sofiani Uni, Mat Udin & Takaoka, n. g., n. sp. is described based on the morphological characteristics of adults and microfilariae found in common treeshrews from Jeram Pasu, Kelantan, Malaysia. The Kimura 2-parameter distance between the cox1 gene sequences of the new species and W. bancrofti was 11.8%. Based on the three gene sequences, the new species forms a monophyletic clade with W. bancrofti and Brugia spp. The adult parasites were found in tissues surrounding the lymph nodes of the neck of common treeshrews.ConclusionsThe newly described species appears most closely related to Wuchereria spp. and Brugia spp., but differs from these in several morphological characteristics. Molecular analyses based on the cox1 and 12S rRNA genes and the ITS1 region indicated that this species differs from both W. bancrofti and Brugia spp. at the genus level. We thus propose a new genus, Malayfilaria, along with the new species M. sofiani.Electronic supplementary materialThe online version of this article (doi:10.1186/s13071-017-2105-9) contains supplementary material, which is available to authorized users.

“…Potential bird parasite genera known from Europe are Cardiofilaria, Chandlerella, Eufilaria , Eulimdana , Pelecitus , Pseudlemdana , Sarconema and Splendidofilaria [12,43-49], some of which are found in common birds such as Blackbirds ( Turdus merula ), Magpies ( Pica pica ) or Great Tits ( Parus major ) ([12,50]), others in domesticated exotic birds [51]. However, only certain Cardiofilaria and Pelecitus species are known to be vectored by culicines from Asia and North America [12,52]. A single record from German birds of prey [47] makes Cardiofilaria pavlovskyi the favourite candidate for our unidentified specimens.…”

Molecular detection of Setaria tundra (Nematoda: Filarioidea) and an unidentified filarial species in mosquitoes in Germany

BackgroundKnowledge of the potential vector role of Culicidae mosquitoes in Germany is very scanty, and until recently it was generally assumed that they are not involved in the transmission of anthroponotic or zoonotic pathogens in this country. However, anticipated changes in the course of global warming and globalization may alter their status.MethodsWe conducted a molecular mass screening of mosquitoes for filarial parasites using mitochondrial 12S rRNA-based real-time PCR.ResultsNo parasites causing disease in humans such as Dirofilaria spp. were detected in about 83,000 mosquitoes tested, which had been collected in 2009 and 2010 in 16 locations throughout Germany. However, minimum infection rates of up to 24 per 1000 mosquitoes were revealed, which could be attributed to mosquito infection with Setaria tundra and a yet unidentified second parasite. Setaria tundra was found to be widespread in southern Germany in various mosquito species, except Culex spp. In contrast, the unidentified filarial species was exclusively found in Culex spp. in northern Baden-Württemberg, and is likely to be a bird parasite.ConclusionsAlthough dirofilariasis appears to be emerging and spreading in Europe, the absence of Dirofilaria spp. or other zoonotic filariae in our sample allows the conclusion that the risk of autochthonous infection in Germany is still very low. Potential vectors of S. tundra in Germany are Ochlerotatus sticticus, Oc. cantans, Aedes vexans and Anopheles claviger. Technically, the synergism between entomologists, virologists and parasitologists, combined with state-of-the-art methods allows a very efficient near-real-time monitoring of a wide spectrum of both human and veterinary pathogens, including new distribution records of parasite species and the incrimination of their potential vectors.

“…By the pattern of localization, the species of the Filariata suborder can be divided into the following groups: parasites of eye and nasal cavities (species of genera Aprocta, Aproctoides, and Skrjabinocta); parasites of air sacs and body cavity (species of genera Diplotriaena, Serratospiculum, Pseudaprocta, Parornithofilaria, and Dicheilonema); parasites of subcutaneous cellular tissue (species of genera Squamofilaria, Ornithofilaria, Hamatospiculum, Petrovifilaria, and Pseudlemdana); parasites of muscle tissue (Sarconema eurycerca, localized in cardiac muscles); parasites of the circulatory system (species of genera Splendidofilaria, Vargifilaria, (Anderson, 1956(Anderson, , 1957(Anderson, , 1962Dissanaike and Fernando, 1965;Sonin, 1966Sonin, , 1968Sonin, , 1971Sonin, , 1975Kabilov, 1983), are intermediate hosts of Filariata.…”
