“…In pigs, the disease was high in stray pigs than farm pigs with high relative risk indicating there easy access to dog's faeces. The results were in parity with many workers (Yildiz and Gurcan 2009;Williams and Sweatman 1963;Thompson et al 1984;Kumaratilake et al 1986) who found similar morphological values in sheep samples. Similar morphological findings were also recorded in the neighbourhood in west Punjab (Pakistan) (Hussain et al 2005) indicating that similar G1 and G3 strains might also be prevalent in that area.…”

The purpose of this study was to document the prevalence and to analyze morphological characteristics from hydatid cysts to test their suitability for strain identification. In the present study, 4,130 animals, including 278 cattle, 298 buffaloes, 760 sheep, 2,439 goat and 355 pigs were examined for the presence of hydatid cysts on postmortem inspection at different slaughter houses/shops in northern India. Morphological characteristics from hydatid cysts were analyzed to test their suitability for strain identification. For statistical analysis, five variables were considered: number of hooks per rostellum, blade length of large and small hooks, and total length of large and small hooks. Principal component analysis was applied for analysis of morphological parameters. Out of a total of 4,130 animals examined, 66 were positive for hydatid cysts (prevalence 1.598 %). The prevalence of hydatid cysts was highest in cattle (5.39 %) followed by buffaloes (4.36 %), pigs (3.09 %), sheep (2.23 %) and goat (.41 %). The results indicate significant prevalence of hydatidosis in all the food producing animals and further that morphological analysis can also be used as a valid criterion for differentiation of different strains of E. granulosus particularly in developing countries where molecular studies could not be performed due to lack of infrastructure or financial constraints.

“…The means of individual isolates from 14 Australian mainland sheep, 2 UK horses, and 1 Egyptian camel are from unpublished data of the Hobbs et al (1990) study. The overall mean of 7 horse isolates is from the data of Kumaratilake, Thompson and Eckert (1986) ; of 7 cattle isolates is from Thompson, Kumaratilake and Eckert (1984) ; and of 21 camel isolates is from Eckert et al (1989). Overall means of 29 camel strain isolates, and 78 sheep strain isolates from Iran are derived from both published and unpublished data from the study of Harandi et al (2002).…”

Molecular and morphological characterization ofEchinococcusin cervids from North America

et al. 2005

View full text Add to dashboard Cite

Many issues concerning the taxonomy of Echinococcus have been resolved in recent years with the application of molecular tools. However, the status of Echinococcus maintained in transmission cycles involving cervid intermediate hosts remains to be determined. The recent characterization of the parasite from cervids in Finland has highlighted the paucity of data available, particularly that from North America. In this study, we have characterized a large number of Echinococcus isolates from cervids from Western Canada on the basis of morphology and molecular genetic techniques. Our results support earlier studies suggesting that Echinococcus of cervid origin is phenotypically and genetically distinct to Echinococcus maintained in domestic host assemblages, and also confirms that Echinococcus of cervid origin does not constitute a genetically homogeneous group. However, our data do not support the existence of 2 distinct genotypes (strains/ subspecies) with separate geographical distributions. Our data appear to support the existence of only 1 species in cervids, but additional isolates from cervids and wolves in other endemic regions should be characterized before a final decision is made on the taxonomic status of Echinococcus in cervids.

“…However, in the UK E. granulosus (G1-G3) has been found in dogs, sheep and cattle whilst E. equinus (G4) has been isolated from horses, dogs and from two captive mammals zebra (Equus burchellii) and lemur (Varecia rubra) (Boufana et al, 2015b). In Ireland, E. equinus has been found in horses and dogs (Hatch, 1970;Kumaratilake et al, 1986). Ireland is not believed to be endemic for other species/genotypes of E. granulosus (Torgerson and Budke, 2003).…”
