Molecular differentiation of Turkey cattle isolates of Fasciola hepatica and Fasciola gigantica

Pubblicato online: 11 Mar 2011
Pagine: 3 - 7

Astratto

Abstract

The most common and widespread liver flukes of the genus Fasciola are Fasciola hepatica and F. gigantica. Adults of both species occur in many domestic ruminants and in humans and can cause serious disease. The differential diagnosis of these flukes infection is very important because of their different transmission and epidemiological characteristics. A simple and rapid PCR-restriction fragment length polymorphism (RFLP) assay, using the common restriction enzymes AluI and RsaI, is described to distinguish between both fasciolid species. After the digestion of the mitochondrial cytochrome c oxidase 1 (CO1) PCR product with the restriction enzyme AluI, the RFLP profile obtained from F. hepatica revealed two fragments, whereas F. gigantica was not cut. The RsaI digestion generated two fragments from F. gigantica, whereas it did not cut the PCR product from F. hepatica. Results were confirmed with CO1 sequence analysis of both F. hepatica and F. gigantica. The present study suggests that the PCRRFLP method described here can be used for the proper identification of Fasciola species.

Parasitic infections and pregnancy complications

Pubblicato online: 11 Mar 2011
Pagine: 8 - 12

Astratto

Abstract

Infections of various aetiology during pregnancy present a serious risk factor that can lead to abortion, premature birth, stillbirth, birth of newborn with genetic developmental defects, or seemingly healthy infant that may develop symptoms later in life. A total of 530 sera of patients from gynaecology departments were examined for antibodies against Toxoplasma gondii, Toxocara spp. and Listeria monocytogenes using ELISA (IgG, IgM). In women with habitual abortions we determined up to 42.1 % seroprevalence of IgG antibodies against T. gondii. The prevalence of antibodies was statistically significant (p < 0.0004) when compared to control group (25.1 %). In the patients diagnosed with sterility the prevalence of antibodies (26.3 %) was similar to that of control group. The prevalence of antibodies against Toxocara spp. (5.5 %) and Listeria monocytogenes (2.3 %) in patients with habitual abortions were similar to those of women in the general population.

Human dirofilariosis: The report of subcutaneous Dirofilaria repens infection in the Slovak Republic

Pubblicato online: 11 Mar 2011
Pagine: 13 - 16

Astratto

Abstract

Dirofilariosis is a vector-borne disease that is spreading in Europe from the southern endemic regions to the northern countries, including Slovakia. The dog parasites Dirofilaria immitis and D. repens are zoonotic agents, responsible for the development of human pulmonary and subcutaneous dirofilariosis, respectively. The present paper reports the third case of human dirofilariosis in Slovakia caused by D. repens. The pacient, a 41-year-old woman, was referred with tumour process in the subcutaneous area of the right forearm. Within 14 days the USG confirmed the rapid increase of the nodule from 20 × 10 mm to 30 × 25 mm. The surgical extirpation of the tumour was indicated. Histological examination revealed the formation with eosinofilic rime and the presence of a worm in the centre, detected as D. repens.

Surface of the filarial parasite Setaria digitata and the structural changes on treatment with Triton X-100

Pubblicato online: 11 Mar 2011
Pagine: 17 - 22

Astratto

Abstract

Setaria digitata, a bovine filarial parasite is used as a laboratory model for filariasis. The studies showed that considerable amount of biochemically and immunologically active materials are present on the surface of the parasite. The effect of Triton X-100 on the surface of the parasite, when it is used to separate the surface associated materials, is not known. Treatment with Triton X-100 enhances the amount of ES protein released into the medium. The electron microscopic study of S. digitata wall showed that structure of the surface is similar to that of W. bancrofti. There are striations, annulations and button like bosses on the filarial surface. On treatment with Triton X-100 the electron dense cloudy layer on the surface was disappeared. The surface appeared to be suitable for hosting secreted molecules on the surface.

Abstract

The intensity and extensity of infestation of cormorants (Phalacocorax carbo sinensis) from a colony in Lake Selment Wielki with the tapeworm Paradilepis scolecina (Rudolphi, 1819) was examined. The cormorants were shot in April, August and October 2006 and in August and September 2007. The extensity of infection in all the cormorants under study was very high — even reaching 100 %. The highest intensity of infestation was found in the birds shot in August — 4697 tapeworms per bird in 2006 and 2562 in 2007. The intensity of infestation in the birds which were shot in autumn was less than one-tenth of that found in the birds shot in summer. The lowest intensity of infestation was found in the spring of 2006 — 61 tapeworms per bird.

Pathology associated with Contracaecum rudolphii (Nematoda: Anisakidae) infection in the great cormorant Phalacrocorax carbo (L. 1758)

Abstract

This is a report of lesions associated with the nematode Contracaecum rudolphii (Nematoda: Anisakidae) from the proventriculus of the great cormorant, Phalacrocorax carbo (L. 1758). The study was undertaken as part of a health monitoring program for P. carbo, which is endangered and thus protected within the European continent. Cormorants were collected by gun-shot from north-eastern Poland in the spring of 2006, four birds were necropsied on site and the gastrointestinal tract was examined for the presence of nematodes. The birds came from a region with noted increases in the cormorant population over the last decade. Esophageal and gastric sections with parasites in situ were fixed in formalin and processed routinely for paraffin embedding, stained with H&E and examined by brightfield microscopy. Parasite associated lesions consisted of severe, ulcerative gastritis at the attachment sites, and diffuse granulomatous gastritis in adjacent areas. Eosinophilic material speculated to be the parasite-derived excretory-secretory product was consistently forming the parasite-host boundry at the attachment points. Although the parasite-associated gastric lesions were focally severe, all examined birds appeared in good body condition. Because only four birds were investigated in this study, the potential contribution of C. rudolphii to morbidity and mortality in great cormorants needs to be examined further.

Abstract

This survey records the occurrence of larvae of Contracaecum multipapillatum sensu lato (Von Drasche, 1882) Lucker, 1941 (Nematoda, Anisakidae) and adults of Floridosentis mugilis (Machado Filho, 1951) Ward, 1953 (Acanthocephala, Neoechinorhynchidae) in mullet Mugil incilis Hancock, 1830 caught in La Boquilla, Cartagena de Indias (Colombian Caribbean coast). The prevalence of F. mugilis was 45.7 % and of C. multipapillatum s.l. 58.6 %, while 28.6 % of the fish were parasitized by both species. The smallest hosts presented the lowest prevalence of F. mugilis but the highest prevalence of C. multipapillatum s.l.. Prevalence, mean abundance and mean intensity of C. multipapillatum s.l. in M. incilis were all highest in viscera. The prevalence in fish muscle tissue was low (2.9 %).

Abstract

Two little-known nematode species of the family Camallanidae, intestinal parasites of marine perciform fishes, are reported from off New Caledonia: Procamallanus (Procamallanus) annulatus Yamaguti, 1955 from the goldenlined spinefoot Siganus lineatus (Valenciennes) (Siganidae) and Procamallanus (Spirocamallanus) monotaxis (Olsen, 1952) from the longspine emperor Lethrinus genivittatus Valenciennes and the slender emperor Lethrinus variegatus Valenciennes (both Lethrinidae). Detailed light and electron microscopical studies (the latter used for the first time in these species) revealed some taxonomically important, previously not observed features, such as the presence of deirids, six crescent-shaped elevations surrounding the mouth, three poorly developed protuberances on the female tail tip and circumcloacal papillae and phasmids on the male tail in P. annulatus, and the presence of a circumoral flange, only 12 (instead of 14 reported) cephalic papillae, the shape of deirids and similar numbers (14–17 and 14–15) of spiral ridges in the male and female buccal capsules in P. monotaxis. The fourth-stage larva of P. annulatus is described for the first time. Firststage larvae of both species were found to possess several digital processes at the tail tip. The present findings represent new host and geographical records of these parasite species.

Abstract

The present study is the first description of the egg morphology, embryonic development, and time required for hatching, and longevity of the oncomiracidium of Heterobothrium ecuadori (Meserve, 1938) Sproston, 1946. Experiments found that hatching time fluctuated between 7 and 10 days with a mean of 7.5 ± 1 days at 23 ± 1° C and 35 ‰. Eggs were provided with a polar filamentous appendage. The body of the oncomiracidium was flattened dorso-ventrally, 156 ± 9 μm long and 65 ± 8 μm wide. A full description of the egg development and morphology of the oncomiracidium is provided. The longevity of the oncomiracidia was 4–7 days at 21 ± 1°C, with a mean survival time of 121.8h. The ability to rear diclidophorids like H. ecuadori and to record precise information on their development provides valuable data for further studies.

Abstract

A one-year-old female Shetland Sheepdog was presented with chronic cough. The patient exhibited tachypnea and moist cough, bronchoscopic examination revealed a hyperaemic trachea and mucopurulent exudate affecting the lower bronchi. Nematode parasites were observed during bronchoscopy and were collected by bronchoalveolar lavage. Microscopic examination of the collected fluid confirmed C. vulpis infection; L1 larvae were found in during coproscopy. Although other cases of canine C. vulpis infection have been previously recorded in Europe, the case reported herein is the first in a dog from Czech Republic.

Abstract

The present study is the first description of the egg morphology, embryonic development, and time required for hatching, and longevity of the oncomiracidium of Heterobothrium ecuadori (Meserve, 1938) Sproston, 1946. Experiments found that hatching time fluctuated between 7 and 10 days with a mean of 7.5 ± 1 days at 23 ± 1° C and 35 ‰. Eggs were provided with a polar filamentous appendage. The body of the oncomiracidium was flattened dorso-ventrally, 156 ± 9 μm long and 65 ± 8 μm wide. A full description of the egg development and morphology of the oncomiracidium is provided. The longevity of the oncomiracidia was 4–7 days at 21 ± 1°C, with a mean survival time of 121.8h. The ability to rear diclidophorids like H. ecuadori and to record precise information on their development provides valuable data for further studies.

Abstract

A one-year-old female Shetland Sheepdog was presented with chronic cough. The patient exhibited tachypnea and moist cough, bronchoscopic examination revealed a hyperaemic trachea and mucopurulent exudate affecting the lower bronchi. Nematode parasites were observed during bronchoscopy and were collected by bronchoalveolar lavage. Microscopic examination of the collected fluid confirmed C. vulpis infection; L1 larvae were found in during coproscopy. Although other cases of canine C. vulpis infection have been previously recorded in Europe, the case reported herein is the first in a dog from Czech Republic.
