During routine necropsy of a 28-year-old horse with intestinal volvulus, numerous hydatid cysts were discovered in the liver. Viable protoscolices of Echinococcus granulosus were obtained from the cyst. As a 4-year-old, this horse had been imported from an area that is enzootic for equine hydatidosis. 相似文献

Sentinel lambs were used to identify young Echinococcus granulosus infections in sheep, to provide an early indication of the progress of the South Powys Hydatidosis Control Scheme. Four sentinel lambs were purchased on each of 60 farms, from inside and outside the control area; they were examined when approximately six, 10 and 15 months of age. Gross examination, thin slicing of organs and histological examination of the lesions in the viscera revealed no E granulosus hydatid cysts in lambs born within the control area, whereas 25 per cent of the 15-month-old lambs from outside the area harboured E granulosus cysts (less than 1 to 2 mm in diameter). Lambs from E granulosus infected farms had significantly higher anti-E granulosus ELISA antibody titres than lambs from uninfected farms. It was concluded that within one year of beginning to treat dogs with praziquantel every six weeks the transmission of E granulosus to sheep had ceased. In contrast, this treatment did not prevent infections with Taenia hydatigena or T ovis; an examination of the 240 lambs revealed T hydatigena in 33.3 per cent of them, Tovis in 4.2 per cent, Dictyocaulus filaria in 12.1 per cent and Meullerius capillaris in 49.2 per cent. 相似文献

In the current study, soluble proteins prepared from 200 mature Echinococcus granulosus and protoscolices of sheep hydatid cysts were applied to immunize sheep and mice respectively. The samples were mechanically homogenized in a blender, sonicated and the final yield was maintained at -20 degrees C until analysis. Hydatid fluid was isolated from liver or lung of sheep under sterile conditions. In the first experiment, 15 mice were randomly allocated to three groups of five mice each. Each mouse in groups 1 and 2 was immunized with 100 microg of hydatid fluid and protoscolex proteins in 100 microl of phosphate-buffered saline (PBS) and emulsified with an equal volume of Freund's complete adjuvant (FCA) respectively. The mice of group 3 were immunized with adjuvant in PBS. The mice were boosted 4 weeks after the first vaccination with the same preparation except that FCA was replaced by Freund's incomplete adjuvant (FIA). In the second experiment, eight male or female lambs 4-6 months of age, were allocated to two groups of four lambs each. Each lamb in the test group was vaccinated subcutaneously in the neck with a 2-ml dose of vaccine (1 mg of whole body protein of E. granulosus dissolved in 1 ml of PBS plus 1 ml of FCA). Control lambs were vaccinated with adjuvant in PBS. Lambs were boosted the same way as in the first experiment. Three weeks after the second vaccination, each mouse and lamb received a challenge infection with 2000 protoscolices intraperitoneally and each lamb additionally received 10 gravid E. granulosus. All mice and sheep were killed after 7 months and examined for hydatid cysts. In these studies, protective immunity was induced in mice with protoscolex protein and with hydatid fluid, and in sheep with whole-body homogenate of E. granulosus and the levels of protection afforded were found to be 72.1, 82.6 and 90.9% respectively. 相似文献

The aim of this study was to develop an immunological method for the identification of sheep infected with Echinococcus granulosus which would allow the monitoring of animals imported into countries free from hydatidosis and as an aid to countries where control schemes for the disease are in operation. Three enzyme-linked immunosorbent assays (ELISAs) were developed and validated, using as antigen either a purified 8 kDa hydatid cyst fluid protein (8kDaELISA), a recombinant EG95 oncosphere protein (OncELISA) or a crude protoscolex preparation (ProtELISA). Sera used for the assay validations were obtained from 249 sheep infected either naturally or experimentally with E. granulosus and from 1012 non-infected sheep. The highest diagnostic sensitivity was obtained using the ProtELISA at 62.7 and 51.4%, depending on the cut-off. Assay sensitivities were lower for the 8kDaELISA and the OncELISA. Diagnostic specificities were high, ranging from 95.8 to 99.5%, depending on the ELISA type and cut-off level chosen. A few sera from 39 sheep infected with T. hydatigena and from 19 sheep infected with T. ovis were recorded as positive. Western immunoblot analysis revealed that the dominant antigenic components in the crude protoscolex antigen preparation were macromolecules of about 70-150 kDa, most likely representing polysaccharides. This study demonstrated that the ProtELISA was the most effective immunological method of those assessed for detection of infection with E. granulosus in sheep. Because of its limited diagnostic sensitivity of about 50-60%, it should be useful for the detection of the presence of infected sheep on a flock basis and cannot be used for reliable identification of individual animals infected with E. granulosus. 相似文献

This study was conducted in order to determine the prevalence and fertility of hydatid cysts in sheep in Kirikkale, Turkey. A total of 3.2% of 553 lambs and 50.9% of 1320 adults were found to be infected with hydatid cysts. The most common locations of cysts were in the liver and lung. Liver cysts tended to be more fertile than lung cysts (81.53% v. 76.47%), though the difference was not significant. The mean number of viable protoscoleces in the liver and lung cysts were 12,400 and 5,800, respectively. In general, 1-10 cysts were found in liver (51.8%) and lung (64.7%). The findings of this study indicate that hydatid cysts are common in sheep and the fertility rate of cysts is quite high. Sheep play an important role in the life cycle of Echinococcus granulosus in this region. 相似文献

In the present study, 115 stray dogs (56 males and 59 females, mixed breed), 86 golden jackal (Canis aureus, 42 males and 44 females), 60 red foxes (Vulpes vulpes, 33 males and 27 females), and three female wolves (Canis lupus) were examined for Echinococcus granulosus infection, as well as, 32,898 sheep, 10,691 goats, 15,779 cattle and 659 buffaloes for hydatid infection from five provinces in western Iran during 3 years (1997-2000). Meanwhile fertility rates of different types and forms of cysts isolated from infected animals and the viability of protoscolices were also determined. Results indicated that 19.1% of the dogs, 2.3% of the golden jackals and 5% of the red foxes were infected with Echinococcus granulosus. 11.1% of the sheep, 6.3% of the goats, 16.4% of the cattle and 12.4% of the buffaloes were also found to be infected with hydatid cyst. The cysts isolated from liver and lungs of the sheep show higher fertility rate than the cysts of liver and lungs of goats, cattle and buffaloes. 相似文献

A 14-year-old male Chapman's zebra had been treated for a cervical granulomatous cellulitis for 3 months prior to sudden death associated with myocardial fibrosis. Incidental findings at necropsy included multiple 3-8-cm unilocular cysts in the liver and lungs. Cysts contained either a clear fluid with or without hydatid sand or a gelatinous substance with foci of mineralization. Light and scanning electron microscopic examination of the hydatid sand revealed free protoscolices as well as intact and ruptured brood capsules with protoscolices attached to the germinal membrane. The protoscolices had 2 rows of 36-38 rostellar hooks with a length of 25-30 microm. The cyst wall consisted of inner germinal, intermediate laminated, and outer adventitial layers. Hydatidosis caused by Echinococcus granulosus was diagnosed based on the unilocular cysts, multiple protoscolices formed in a brood capsule, typical trilayered cyst wall, and herbivorous intermediate host. This is the first reported case of animal hydatidosis in Taiwan. The infection is thought to have been established 12 years ago in South Africa prior to importation. 相似文献

The aim of this study was to determine the fertility and viability of hydatid cysts in slaughtered sheep and cattle. Cysts
were collected from the liver and lungs of 169 sheep and 171 cattle infected with Echinococcus granulosus when slaughtered
in industrial abattoir in Sari, Iran, 2007–2008. Fertility was determined by the examination of cyst fluid for the presence
of protoscoleces. The viability of the protoscoleces was assessed by staining with 0.1% aqueous eosin solution. The fertility
rates of hepatic cyst of sheep and cattle were 47.1% and 1.4%, respectively and the fertility rates of pulmonary cyst of sheep
and cattle were 39.4% and 8.1%. In the sheep, the fertility of cysts in the liver was higher than that in lungs, but in the
cattle the fertility of cysts in lungs was higher than liver. The viability of protoscoleces of fertile cysts for sheep and
cattle were about 76.9% and 82.5%, respectively. Based on the finding in the present study, effort should be made to control
transmission of cystic echinococcosis by safe disposal of Echinococcus cysts such that dogs cannot have access to the cysts. 相似文献
