Notes on Helminthofauna of the Caucasian Toad, Bufo Verrucosissimus (Pallas, 1814)

Abstract

The purpose of the research is to study helminthofauna of Caucasian toad in vivo and in vitro. Materials and methods. Researches were conducted in vivo and in laboratory setting (Russian State Agrarian University -Moscow Timiryazev Agricultural Academy). Fecal from mature animals catching in six places in the north Caucasus andTranscaucasia during April-May 2012-2015 were investigated. Specimen of animals contained in laboratory during 1-4 years after catching and born in vitro have also be analyzed. Method of sequential irrigation was used for detachment helminths and their ootids. Died animals were anatomized according to Skryabin's method. Total 200 fecal samples of bufo in vivo and 150 samples of animals from laboratory have been studied.Results and discussion. Results and discussion. Eggs and adult proboscis worms of four species have been found in fecal of Caucasian toad:

A new species ofPseudoacanthocephalus(Acanthocephala: Echinorhynchidae) from the guttural toad,Sclerophrys gutturalis(Bufonidae), introduced into Mauritius, with comments on the implications of the introductions of toads and their parasites into the UK

“…It is not referred to by Kennedy (2006) in his discussion of acanthocephalan life cycles and their transmission. The only record we could find of such an event happening was from Kidov et al (2018), who reported finding adults of Acanthocephalus falcatus (Froelich, 1789), A. ranae (Shrank, 1788), P. bufonis and Pseudoacanthocephalus caucasicus (Petrochenko, 1953) in the Caucasian toad Bufo verucossismus (Pallas, 1814). Perhaps the phenomenon is more common in toads than the literature would suggest but has previously gone unnoticed.…”
