Echinococcus multilocularis is a frequent parasite of red foxes (Vulpes vulpes) in Latvia

Pubblicato online: 11 Jan 2009
Pagine: 157 - 161

Astratto

Abstract

45 red foxes (Vulpes vulpes) from various regions of Latvia were examined by necropsy between 2003 and 2008 for the presence and infection intensity of Echinococcus multilocularis. The overall prevalence was 35.6 %, with the intensity of infection ranging from 1 to 1438. Although a limited number of foxes were examined, the prevalence was high and infected animals were found throughout the country. Considering the increasing number of humans infected with echinococcosis in Latvia since 2002, the situation is highly suggestive of a recent emergence of E. multilocularis. DNA sequences of four fox isolates were examined by multilocus analysis of mitochondrial and nuclear genes (cox1, nad1, rrnS, atp6, actII). All isolates were allocated to the predominant genetic form in Europe, with partial affinity of one isolate to a genotype that had previously been reported from southern Germany.

Two remarkable pinworms (Nematoda: Enterobiinae) parasitizing orangutan (Pongo abelii) in the Sumatra (Indonesia) including Lemuricola (Protenterobius) pongoi n.sp.

Abstract

Two species of pinworms (Enterobiinae) were collected from fresh faeces of semi-wild orangutans Pongo abelii Lesson living in northern Sumatra (Indonesia). The female of Enterobius (Enterobius) buckleyi Sandosham, 1950 is redescribed. Lemuricola (Protenterobius) pongoi n. sp. is described on the basis of females (no males are available) and distinguished from L. (P.) nycticebi (Baylis, 1928) by cephalic and mouth morphology (head and teeth superstructures), body (9.85–15.46 mm) and tail (2.34–2.95 mm) length, smaller eggs (48–56 x 22–28 μm), longer vulva distance from anterior extremity (2.05–3.09 mm) and other features. Characteristic is the total body length/oesophagus length ratio (1: 15.3–22.0). Both nematode species were studied using scanning electron microscopy for the first time.

A case of complicated cerebral toxocariasis in a 4-year old child

Pubblicato online: 11 Jan 2009
Pagine: 169 - 172

Astratto

Abstract

We report the case of a 4-year-old boy suffering from a cerebral form of toxocariasis. High serum titres of anti-Toxocara antibodies indicated that the primary infection was induced by a high number of Toxocara eggs and that the larvae did not penetrate to cerebrospinal fluid due to the hematoencephalic barrier. MRI of the patient’s brain showed multiple focal lesions spread diffusely in almost all parts of the brain, predominantly paraventricularly. These might be eosinophil-rich granulomatous infiltrates enclosing larvae. Extensive morphological changes were the cause of serious neurological symptoms, most of them being reversible after follow-up therapy. Radiology proved to be useful diagnostic method, but the specific serological assessment had a key role for the final diagnosis. In conclusion, diagnosis of this patient was intracranial primary Toxocara infection with central quadruparesis and parainfective myocarditis.

Fuhrmanolepis beskydensis n.sp. (Cestoda: Dilepididae) from woodcock Scolopax rusticola L.(Aves, Charadriformes) in Slovakia with comments on sytematics and nomenclature of the genus Fuhrmanolepis Spassky et Spasskaya, 1965

Abstract

Fuhrmanolepis beskydensis n.sp. from woodcock, Scolopax rusticola L. in Slovakia is described based upon light microscope observation. The medium sized species possess a single crown of 21‘diorchid’ (wrench-shaped) hooks, 28–30 μm long. Irregularly alternating genital pores were combined with abnormal multiple shifting of pores within the lateral margins of strobila. Number of testes 18–25. Cirrus-sac and evaginated cirrus are 115–135 × 7–12 and 26 × 6–11 μm, respectively. The species is differentiated from closely related congeneric taxons and some other morphologically similar dilepidids. An attention is being paid to taxonomy and nomenclature of Fuhrma n olepis Spassky et Spaskaja, 1965 regarding an emendation of mentioned genus to Fuhrma nn olepis by Bona (1994a) and modification of its diagnosis.

A checklist of helminth fauna of weatherfish, Misgurnus fossilis (Pisces, Cobitidae): state of the art, species list and perspectives of further studies

Abstract

The helminth fauna of weatherfish (Misgurnus fossilis) in natural range is reviewed. Several helminth species reported in weatherfish are discussed with reference to host specificity and their geographical distribution. The current list of helminth parasites of the weatherfish includes 37 species. Most (15) are digenean trematodes, half of them being larval stages. Only one species of trematode — Allocreadium transversale is more specific parasite of weatherfish. Second largest group are Monogenea, with 10 species. Two of them (Gyrodactylus strelkovi and G. misgurni) are found only in the genus Misgurnus. Tapeworms (6 species) and Nematodes (6 species) are less numerous. No Acanthocephala, however, were ever found.

Seasonal variation in parasite occurrence and microhabitat distribution of monogenean parasites of gudgeon Gobio gobio (L.)

Abstract

Seasonal changes in occurrence, infracommunity composition and microhabitat distribution of the monogenean parasites of gudgeon Gobio gobio (L.) were studied during two years in the River Haná (Czech Republic). Altogether 212 specimens of gudgeon were examined and a total of 6456 specimens of eight monogenean species were recorded: Dactylogyrus cryptomeres, Gyrodactylus gobiensis, Gyrodactylus gobii, Gyrodactylus gasterostei, Gyrodactylus vimbi, Gyrodactylus markakulensis, Gyrodactylus sedelnikowi and Paradiplozoon homoion. The occurrence of monogeneans correlated with seasonal changes of water temperature. In 2001, gyrodactylids peaked in March and D. cryptomeres in May, whereas in 2002, gyrodactylids peaked in May and D. cryptomeres in July. The majority of specimens of all Gyrodactylus species were found on the fins; the remaining specimens of Gyrodactylus were located on the body surface and gills, and all Dactylogyrus and Paradiplozoon specimens were located on the gills. The microhabitat distribution of the monogeneans changed in relation to changing water temperature and intensity of infection.

Abstract

The present paper summarized data on parasites of percid fishes (Actinopterygii: Percidae), such as pike-perch, European perch and ruffe from estuaries of the Polish coastal zone are listed, based on published records and long-term surveys carried out by the author. Parasites are listed alphabetically, separately for each host and for each parasite group with notes on their location on the host and geographical distribution (with references). A total of 41 species (taxa) of parasites were recorded on pike-perch Sander lucioperca (6 Ciliophora, 1 Myxozoa, 1 Monogenea, 11 Digenea, 4 Cestoda, 6 Nematoda, 5 Acanthocephala, 1 Mollusca, 1 Hirudinea, 4 Copepoda and 1 Branchiura). European perch, Perca fluviatilis, harboured 60 parasites (6 Ciliophora, 4 Myxozoa, 1 Monogenea, 18 Digenea, 9 Cestoda, 10 Nematoda, 5 Acanthocephala, 1 Mollusca, 1 Hirudinea, 4 Copepoda and 1 Branchiura). Ruffe Gymnocephalus cernuus featured 43 parasites (1 Microsporidia, 7 Ciliophora, 3 Myxozoa, 1 Monogenea, 13 Digenea, 5 Cestoda, 8 Nematoda, 2 Acanthocephala, 1 Mollusca and 2 Copepoda).

Effects of land use history and inoculation with Fusarium oxysporum f. sp. cucumberinum Owen on soil nematodes communities

Abstract

A pot culture experiment was carried out to study the effects of land use history and inoculation with Fusarium oxysporum f. sp. cucumberinum Owen (Foc) on soil nematodes communities during the cucumber growing season in 2007. The results showed that land use history and inoculation had significant effects on the abundance and diversity of soil nematodes. Bacterivores were found to be the most dominant group in this study. Irrespective of inoculation, numbers of fungivores, plant-parasites and values of trophic diversity index (TD) and plant-parasites index (PPI) were greater in greenhouse soils (GH) than in open field vegetable soils (OF) during the growth period of cucumber. While, the number of omnivores-predators and values of richness (SR) and maturity index (MI) presented an opposite trend. Foc inoculation had noticeable effects on numbers of plant-parasites and some taxa, such as Helicotylenchus, Epidorlaimus at flowering stage and Aphelenchus, Tobrilus at fruiting stage. Besides, inoculation significantly affected values of PPI at flowering stage and TD at fruiting stage, respectively. The faunal analysis showed that soil food web in GH was highly disturbed and in OF was degraded.
