Each gill arch was examined and the number of metacercarial cysts counted.
Total worm or cyst counts were made for each rabbit.
Aggregates consisted of three or more metacercarial cysts, separated from each other by a distance of 200 mm or less.
The number of metacercariae forming cyst associations was reduced and, at low concentrations, an increase in the number of floating metacercarial cysts occurred.
It is also possible that septic or sewage treatment systems are probable environmental sources of giardia cyst contamination.
The control mice and those that received 25 cysts showed progressive weight gain, whereas the heavily infected mice maintained their weight (fig. 1).
Serial sections were made to identify the organisms contained within the grossly observed small cysts.
A feature of the study was the determination of the viability of protoscoleces from hydatid cysts of livestock.
