Echinococcosis
WHO supports the development of a new internationally standardised classification of ultrasonographic images in cystic echinococcosis.1 The classification will enable recommended treatments for the different cyst types, and worldwide comparisons of cyst types, which may also provide evidence for strain differences in Echinococcus granulosus.
For management the cysts are divided into three main groups: active, transitional, and inactive (figure 1). Active cysts are simple cysts or cysts
Echinococcosis
PAIR and other procedures less invasive than conventional surgery (radiofrequency thermal ablation, percutaneous evacuation) are being developed for treating large cysts containing multiple daughter cysts.14 To modify the WHO classification CE3 cysts should be subdivided into cysts with water-lily sign and other transitional cysts. Multi-centre studies are needed to find the best management of echinococcosis. Epidemiology of and disease activity in multilocular and polycystic echinococcosis are
Conclusion
Technical progress will provide smaller, better, and cheaper ultrasound devices, which will make the technique more widespread, even in poor countries. Because ultrasonography is operator-dependent, the distribution of machines must be accompanied by adequate teaching and quality con-trol.17 Educational structures for training in ultrasonography vary from country to country, which makes it difficult for imagers from developing countries to gain a recognised qualification. Criteria are needed to

2017, Small Ruminant ResearchCitation Excerpt :Other parasitic infections causing tissue lesions have also been readily diagnosed by use of ultrasonographic examination. These include Fasciola infections (Bassily et al., 1989; Aksoy et al., 2005; Koc et al., 2009), where it could also guide therapeutic management of the disease (Alatoom et al., 2008), schistosomiosis (Doehring-Schwerdtfeger and Kardorff, 1995), lymphatic filariosis (Poltera and Zak, 1988; Mand et al., 2005) and liver abscesses associated with Ascaris infections (Javid et al., 1999; Richter et al., 2003). In animal species other than sheep, ultrasonographic examination can be of value as an adjunct to clinical examination in adult horses, used to detect intra-arterial changes associated with Strongylus vulgaris infections (Wallace et al., 1989a,b,c), as well as in foals, used to detect the characteristic intestinal dilation with intraluminal presence of ascarids associated with Parascaris equorum infection (Tatz et al., 2012; Nielsen et al., 2016).
