This is the first review of the helminth fauna of the moor frog Rana arvalis Nilsson, 1842 from the Volga river basin (Russia). The article summarizes the authors’ and literature data on the helminthic fauna of this species. The method of complete helminthological dissection was used. Thirthy-eight helminth species were recorded from three classes: Cestoda (1), Trematoda (28), and Chromadorea (9). Nine helminth species are new to the moor frog in Russia: trematodes Gorgodera varsoviensis Sinitzin, 1905, Strigea falconis Szidat, 1928, larvae, Neodiplostomum spathoides Dubois, 1937, larvae, Tylodelphys excavata (Rudolphi, 1803), larvae, Pharyngostomum cordatum (Diesing, 1850), larvae, Astiotrema monticelli Stossich, 1904, larvae and Encyclometra colubrimurorum (Rudolphi, 1819), larvae, nematodes Strongyloides spiralis Grabda-Kazubska, 1978 and Icosiella neglecta (Diesing, 1851). The cestode Spirometra erinacei (Rudolphi, 1918), larvae were observed of this amphibian species in the Volga basin for the first time. The nematodes Rhabdias bufonis, Oswaldocruzia filiformis, Cosmocerca ornata and the trematode Haplometra cylindracea form the core of the helminth fauna of the moor frog. Information on species of helminths includes systematic position, localization, areas of detection, type and scheme of life cycle, geographical distribution, and degree of specificity to host amphibians.

Few Data

The helminthofauna of Bombina bombina (Linnaeus, 1761) has been studied to an unequal degree in different parts of the habitat. Thus, it has been studied in more detail in the west of its range (in the countries of central and eastern Europe) and in less detail in the center (in Belarus and Ukraine). There were few data on helminths of this host in the east of its range (in Russia). For the first time, an inventory of the helminthofauna in B. bombina was carried out for populations in the Volga River Basin. The results of our own research are presented and supplemented with information from other authors. We summarized scattered data on helminths from 390 specimens of amphibians collected over more than 40 years in the territory of five regions: Kaluga and Samara regions, the Republics of Mordovia, Tatarstan and Bashkortostan. The helminthofauna includes 21 species from three classes: Trematoda (15), Chromadorea (5) and Clitellata (1). For each species, we give the systematic position, localization, places of detection, geographical distribution and characteristics of the life cycle. The leech Helobdella stagnalis (Linnaeus, 1758) was first recorded in the European fire-bellied toad in Europe. Four species of trematodes are new to this amphibian species in Russia: Haematoloechus abbreviatus (Bychowsky, 1932), Paralepoderma cloacicola (Luhe, 1909), larvae, Tylodelphys excavata (Rudolphi, 1803), larvae and Astiotrema monticelli (Stossich, 1904), larvae. Another species of trematode – Strigea strigis (Schrank, 1788), larvae – was first recorded in this host within the boundaries of the Volga Basin. A specific parasite is the trematode Haematoloechus abbreviatus (Bychowsky, 1932). The number and composition of the species of helminths of the European fire-bellied toad vary in different regions; the structure of the helminth fauna is generally stable and includes three groups of species: adult and larval stages of trematodes, adult nematodes-geohelminths. The results of the study create a database for further population studies and contribute to the development of ideas about the distribution and formation of the amphibian helminth fauna in Europe, Russia and the Volga Basin.

AbstractIn this paper we considered information on the helminth fauna of the European common brown frog (Rana temporaria Linnaeus, 1758) from 10 regions of the Volga basin. This study includes consolidated data of different authors over the last 30 years, supplemented by the results of our own research. There are reliably known finds of 29 species of helminths: Monogenea — 1, Trematoda — 21, Nematoda — 7. Trematodes Gorgodera asiatica Pigulevsky, 1945, Paralepoderma cloacicola (Luhe, 1909), mtc. and nematodes Icosiella neglecta (Diesing, 1851) were observed for the first time in a given host on the territory of Russia and the Volga Basin. Six species of worms make the basis of helminth fauna: nematodes Rhabdias bufonis, Oswaldocruzia filiformis, Neoxysomatium brevicaudatum and Cosmocerca ornata, trematode Haplometra cylindracea and monogenea Polystoma integerrimum. These six species are the most common and widespread parasites of the brown frog. For each species of helminths there is the following information included: taxonomic position, localization, area of detection, biology, definitive hosts, geographic distribution, the degree of host-specificity.

Objetive. Present a modern review of the nematodes fauna of the pool frog Pelophylax lessonae (Camerano, 1882) from Volga basin populations on the basis of our own research and literature sources analysis. Materials and methods. Present work consolidates data from different helminthological works over the past 80 years, supported by our own research results. During the period from 1936 to 2016 different authors examined 1460 specimens of pool frog, using the method of full helminthological autopsy, from 13 regions of the Volga basin. Results. In total 9 nematodes species were recorded. Nematode Icosiella neglecta found for the first time in the studied host from the territory of Russia and Volga basin. Three species appeared to be more widespread: Oswaldocruzia filiformis, Cosmocerca ornata and Icosiella neglecta. For each helminth species the following information included: systematic position, areas of detection, localization, biology, list of definitive hosts, the level of host-specificity. Conclusions. Nematodes of pool frog, excluding I. neglecta, belong to the group of soil-transmitted helminthes (geohelminth) and parasitize in adult stages. Some species (O. filiformis, C. ornata, I. neglecta) are widespread in the host range. The latter two are able to reach high invasion indices and also to be the background parasites of the pool frog. It happens due to these nematode species life cycle specificity and the long-term connection of the amphibian with water.

Summary In the years 2012-2014, carcasses of 286 birds of prey from the territory of Slovakia were examined for the presence of helminth parasites. The number of bird species in the study was 23; five belonging to the Falconiformes order, eleven to Accipitriformes, and seven to Strigiformes. A finding of Cestoda class comprehended 4 families: Paruterinidae (4), Dilepididae (2), Mesocestoididae (2) and Anoplocephalidae (1). Birds of prey were infected with 6 families Nematoda species of the Secernentea class: Syngamidae (1), Habronematidae (2), Tetrameridae (3), Physalopteridae (1), Acuariidae (1), and Anisakidae (2). Out of the Adenophorea class, the Capillariidae family (1) was confirmed. The Acanthocephala group was represented by the Paleacanthocephala class, the Centrorhynchidae family (3). Out of the Trematoda class, 12 different species of flukes were found, belonging to the Diplostomidae (5), Cyathocotylidae (1), Strigeidae (4), Opistorchidae (1), and Plagiorchidae (1) families. The most frequent helminth species infecting diurnal birds of prey was Strigea falconis. This fluke was confirmed in one bird species from the Falconiformes order and in eight species from the Accipitriformes order. In nocturnal birds of prey, the most common finding was the acanthocephalan Centrorhynchus aluconis, identified in four different host species of the Strigiformes order. In total, 23 helminth species were recorded for the first time in Slovakia.

Helminthological autopsies of Mustelids from various districts of Pskov, Тver and Smolensk region were carried out. To determine the prevalence rates of the infestation, an extensive invasion index was used. According to the results of helminthological autopsies, a list of detected helminthes is given. For the first time on the study area, 14 species of helminthes were recorded in studied Mustelids. Two of the found species of helminthes parasitize in Mustelids in larval form. The maximum variety of species is observed among the Nematoda class. The data on the number of detected helminth species in Mustelids in certain districts of the Tver, Pskov and Smolensk regions, as well as indicators of the frequency of helminthes were given. The maximum number of helminth species is recorded in Mustelids in the Novosokolnichesky district of the Pskov region. Extensiveness of invasion of all studied species of Mustelids, excluding otter, is 100%. According to the indicators of extensiveness of invasion in the studied Mustelids, Isthmiophora melis, Capillaria mucronata, Capillaria putorii, Filaroides martis are prevalent. The maximum number of species of parasitic worms is recorded in pine marten. The research results indicate the dominant influence of the trophic factor in the formation of the helminth fauna of martens that inhabit the study areas.

AbstractThe helminth fauna of the barbary partridge (Alectoris barbara) in Tenerife Island (Canary Archipelago) was studied from 2001 to 2002, as there were no records of helminths from this host in the Canary Islands. Seven helminth species were identified: two cestodesChoanotaenia infundibulumandLyruterina nigropunctata, and five nematodesAonchotheca caudinflata,Baruscapillaria obsignata,Eucoleus annulatus,Ascaridia galliandHeterakis gallinarum.Lyruterina nigropunctata,A. galli and E. annulatusare recorded for first time inA. barbara. An analysis of available data onAlectorisspp. reveals the importance of intermediate hosts such as arthropods and earthworms in the diet of partridges. Terrestrial helminths are dominant species, with monoxenous and heteroxenous species being present in similar numbers in differentAlectorisspecies along their geographical distribution. Helminth species found in Tenerife fromA. barbaraare poor indicators of the host colonization from North Africa because these helminths are species that are commonly found in fowl with a cosmopolitan distribution.

AbstractThe helminth fauna in 109 Eurasian otters (Lutra lutra L.) from France, Portugal and Spain was analysed, together with 56 faecal samples collected in Portugal and 23 fresh stools from otters included in a reintroduction programme. Seven helminth species were found in L. lutra in southwest Europe: Phagicola sp. (Trematoda), Aonchotheca putorii, Eucoleus schvalovoj, Strongyloides lutrae, Anisakis (third stage larvae) and Dirofilaria immitis (Nematoda), and Gigantorhynchus sp. (Acanthocephala). Eucoleus schvalovoj was the dominant species throughout southwest Europe. Strongyloides lutrae was significantly more prevalent in the Iberian Peninsula than in France. Apart from these two dominant nematodes and A. putorii, the other helminth species were incidental parasites of L. lutra in southwest Europe. The helminth fauna of L. lutra in southwest Europe is, in general, poorer than that reported in eastern Europe and in all other aquatic mustelids in southwest Europe. Phagicola specimens are reported for the first time in a non-marine wild carnivore in Europe. The prevalences of E. schvalovoj and S. lutrae obtained by necropsy were higher than those observed by coprological analysis using a formalin-ether concentration method (Ritchie). Nevertheless, the culture of fresh faeces appears to be the best method to study infection of L. lutra by Strongyloides.

The article describes the process of tench growing (male and female species removed from set gear in the Volga river in the Astrakhan region) using experimental feedstuff "T", taking into account the fact that problems with artificial growing tench ( Тinca tinca ) appear first in the process of feeding when wild sires change to artificial food. The research took place on the base of the department of aquaculture and water bioresources of Astrakhan State Technical University in innovation centre "Bioaquapark - scientific and technical centre of aquaculture" in 2015. Special feed including components of animal origin - mosquito grab and sludge worm as an effective substitute to fish flour, as well as components of vegetable origin (carrot, parsley, pumpkin, wheatgrass) for domestication of tenches are offered for the first time. Food technology has been described. The exact composition of the formula, which is being licensed at the moment, is not disclosed. Feed "T", which has undergone biological analysis and is in accordance with organoleptic and physical standards was used for feeding tench female and male species during domestication period (60 days), along with food "Coppens" (Holland). Feed efficiency was determined according to survival and daily fish growth. Growth rate of females appeared more intensive than growth rate of males fed with experimental food "T". Daily growth changed depending on the types of food: from 0.3 ("Coppens") to 0.47 (experimental food) in females, from 0.25 ("Coppens") to 0.39 (experimental food) with males. Ability to survive among tench species fed with "Coppens" and experimental food made 60% and 100%, correspondingly. Nutricion of tench species with experimental food encouraged their domestication, which allowed using tench species in further fish breeding process in order to get offspring. The project was supported by the Innovation Promotion Fund in terms of the project "Development and implementation of the technique for the steady development of aquaculture: food "TechSA".
