Spring Migrant

The digestive tracts of one local, eight spring migrant, and 16 fall migrant bufflehead ducks (Bucephala albeola L.) collected at Delta, Manitoba, were examined for helminths. Twenty-five species (5 nematode, 8 trematode, 11 cestode, and 1 acanthocephalan) were found. Thirteen species occurred in both spring and fall migrants, four occurred in spring migrants only, and six were found only in fall migrants. The species composition of the helminth fauna of buffleheads resembles that of lesser scaup more closely than that of any other anatid species studied to date.

ABSTRACTFive cestode, one monogenean, and two nematode species comprised the “normal” intestinal helminth fauna of Raja naevus in British waters. An additional two nematodes, a digenean, an acanthocephalan and a crustacean recorded are considered to be accidental infections. Geographical differences in the species composition and level of infection are noted and discussed. Short descriptions of the tetraphyllidean cestode Echeneibothrium sp. and the nematode Capillaria sp. are given, but the species, although probably both new, are left unnamed. The intensity of cestode infections show two patterns associated with host length and these are discussed in relation to variations in host diet. Speculations are made on the cestode life cycles. Only Echeneibothrium sp. numbers showed any significant variation associated with host sex.

The Western Region

The article presents the results of studying the species composition of helminth fauna of the jackal (Canis aureus) in the western region of Kazakhstan. The studies were carried out by coprological methods, the method of complete helminthological dissection, and swabs from the limbs were carried out for oocysts of protozoa and helminth eggs. As study results showed, the highest infection rate is observed for helminth species such as Uncinaria stenocephala, Dipylidium caninum, Toxocara canis, and Trichinella spiralis. The epizootology of parasitic diseases of wild animals is poorly studied, and many unclear questions remain, in particular, what factors serve as triggers for outbreaks of invasive animal diseases. There are many types of helminths parasitizing in domestic animals and their wild relatives, which cause severe diseases in both groups of animals that are often fatal if they have appropriate qualitative and quantitative composition. They include causative agents of echinococcosis, fascioliasis, coenurosis, dictyocaulosis, dicroceliasis of gastrointestinal strongylatosis, etc. As a result, huge losses are caused to natural populations of wild animals and the country's economy in general due to lower productivity and death of animals. Given that the jackal helminth fauna shows a high degree of similarity to domestic carnivores, it should be assumed that when these wild animals come into contact with farm animals, they can exchange parasites. Therefore, it should be assumed that any studies regarding helminthiases of this animal of Kazakhstan form the material of undoubted scientific and practical interest.

Parasites of spawning pacific herring (Clupea pallasii Valenciennes in Cuvier et Valenciennes, 1947) from the Taui population are explored on the samples caught on two spawning grounds located in the Ola lagoon and Amakhton Bay (Tauiskaya Guba Bay, Okhotsk Sea), and 17 species of helminthes are found, including 6 trematodes, 5 cestodes, 4 nematodes, and 2 acanthocephalans. Some differences in species composition of helminthes and their infestation were found between these estuarine and marine spawning grounds. In the Ola lagoon, 16 species of helminthes were identified, including 5 species of cestodes, whereas only 13 species of helminthes, including 3 species of cestodes, were found in the Amakhton Bay. The Taui population of herring is distinguished from the Okhotsk and Gizhiga-Kamchatka populations by presence of nematodes Hysterothylacium aduncum, l, and Ascorophis pacificus with rather high rates of invasion (occurence = 52.9 %; mean abundance = 4.16) and trematode Bucephaloides spp. On the other hand, the herring from the Taui population has common dangerous parasites with other populations in the Okhotsk Sea, as trematode Brachyphallus crenatus and nematode Anisakis spp. (larvae), with high degree of infestation.

A necropsy of lungs from mouflons, chamois, red deerand fallow deer from Bulgariawas performed aiming at determining the species composition of protostrongylids. For the first time in the country Muellerius capillaris, Cystocaulus ocreatus, Neostrongylus linearis, Protostrongylus rufescens, P. hobmaieri are reported as part of the helminth fauna in the mouflon, M. capillaris, N. linearis and P. rupicaprae are reported from the chamois, and Varestrongylus sagittatus is reported from the red deer. This is the first record of P. hobmaieri, P. rupicaprae and V. sagittatus for the fauna of Bulgaria. Some morphological data of males and first stage larvae of P. hobmaieri on materials from the present study are presented

Long Term Studies

As a result of long-term studies, it has been identified that the effects of anthropogenic factors on the formation of helminth fauna of domestic carnivores are reflected in a number of changes. Thus, primarily due to the change in habit of animal, the quantitative and qualitative changes have happened in the helminth fauna: new species of helminths which assume epizootic and epidemiological significance has been found and this has significantly enriched the species composition of the helminth fauna. Due to the influence of anthropogenic factors, the mixed parasitic focuses have formed and 14 species of helminths have included in helminth fauna. The domestic carnivores infected with pathogenic helminths from this focus infect human beings, domestic and ruminating animals from sinantropic focus. Thus, due to impact of the anthropogenic factors, the helminth fauna of animals has changed and has acquired its modern helminthological status.

The purpose of the research: the study of structure and seasonal dynamics of the species composition of helminth fauna of the great tit from Samarskaya Luka. materials and methods. 60 individuals of the great tit were examined by the method of complete helminthological dissection. The catching of birds was carried out with trapping nets. Parasitological objects were treated according to standard methods. The obtained data were statistically processed using the Kovnatsky dominance index, Kruskal-Wallis H test and Mann-Whitney U test. Results and discussion. Helminth fauna of the great tit from Samarskaya Luka was studied for the first time. The analysis of the structure and seasonal dynamics of the species composition of bird parasites was carried out. Helminth fauna of the great tit includes 11 parasite species. Cestodes and trematodes (5 species each) form the basis of helminth fauna. Only one nematode species (Physocephalus sexalatus, larvae) was revealed in tits. For the first time, the cestode Emberizotaenia reductorhyncha was found in birds from the Volga Basin. The great tit was registered as a new host for cestodes Wardium farciminosa and Passerilepis spasskii. Seasonal dynamics of helminth fauna of the great tit is connected with appearance or disappearance of rare parasites. Altogether, two parasite species occur in birds in all year seasons. The greatest diversity of parasites is observed in summer (11 species). In autumn (7) and spring (2) the parasite fauna is less abundant and diverse. Keywords

ABSTRACTPrevalence and intensity of helminth parasites are described for a sample of 102 Jamaican anole lizards representing 6 species (Anolis lineatopus lineatopus, A. I. neckeri, A. grahami, A. valencienni, A.opalinus, A. sagrei, A. garmani). Fifty nine per cent of lizards were infected with 5 species of nematodes, 16% with one acanthocephalan, 7% with two digeneans, and 4% with a single cestode species. Infection intensity was generally low (intensity range 1–5) although two species of nematode occurred in very large numbers (intensity range 1–436). Helminth prevalence patterns and species composition reflected differences in anole habitats rather than ecomorphs, and were uncorrelated with the genetic relatedness of indigenous versus introduced anole species.
