Eksempler på cyst

• This discrepancy in the inhibitory effect on excystment may be due to differences in the permeability of the cyst wall.

• 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.
