In mice DA normally first appear in the neck region of the worm but subsequently they appear elsewhere and increase in number until destrobilation or worm expulsion. The posterior of destrobilated worms is often darkened. In the more immunogenic infections with six cysticercoids there are more DA per worm than in infections with one cysticercoid. DA are areas of the tegument with a homogeneous increase in electron density; abnormal mitochondria; reduced granular endoplasmic reticulum, Golgi complexes and discoidal secretory bodies; and accumulation of lipid droplets. DA disappear from worms maintained for up to 4 h in Hanks' balanced salt solution and can be induced by mechanical damage to the worms.<\/jats:p><jats:p>As the numbers of DA increase with the duration and intensity of infection and have similarities with types of cell injury, they are probably sites of worm pathology induced by host immunity.<\/jats:p>","DOI":"10.1017\/s0031182000047284","type":"journal-article","created":{"date-parts":[[2009,6,5]],"date-time":"2009-06-05T16:57:35Z","timestamp":1244221055000},"page":"525-534","source":"Crossref","is-referenced-by-count":30,"title":["Possible immunological damage to the tegument of<i>Hymenolepis diminuta<\/i>in mice and rats"],"prefix":"10.1017","volume":"71","author":[{"given":"A.
