Depending on the geographical situation, the nature of infected hosts and the sites of infection, cysts may have different fertility rates. In both cases these dimensions do not include the thickness of the cyst wall. Cyst counts were transformed to instantaneous rates of infection. The walls of the cysts contain prominent smooth muscle and elastic tissue. Investigation of the latter would be assisted by tests able to distinguish between infection acquired from oocysts or tissue cysts. In the heart, tissue cysts were in the pericardium, myocardium, endocardium and in the mitral valves. A feature of the study was the determination of the viability of protoscoleces from hydatid cysts of livestock. Serial sections were made to identify the organisms contained within the grossly observed small cysts. The control mice and those that received 25 cysts showed progressive weight gain, whereas the heavily infected mice maintained their weight (fig. 1). It is also possible that septic or sewage treatment systems are probable environmental sources of giardia cyst contamination. The number of metacercariae forming cyst associations was reduced and, at low concentrations, an increase in the number of floating metacercarial cysts occurred. Aggregates consisted of three or more metacercarial cysts, separated from each other by a distance of 200 mm or less. Total worm or cyst counts were made for each rabbit. Each gill arch was examined and the number of metacercarial cysts counted. These examples are from corpora and from sources on the web.
