Abstract


 


The purpose of the research was to study a tissue cyst formation time Toxoplasma gondii
experimentally. A number of 84 mice were divided randomly into four groups. Each group consisted of 21
mice. The mice of the group I were infected with 10
1
, II with 10
2
and III with 10
tachyzoites respectively
intraperitoneally, whereas the group IV as a control (not infected with tachyzoites). All infected mice
were treated with sulfadiazine, 15 mg/mouse per oral diluted in drinking water, for 5 days. On first until
twenty first day after treatment one mouse of each group was necropsied. Liver, lymph, kidney, lung,
heart, brain, or diaphragm muscle were then taken for histological preparations. Data on tissue cyst
formation time was analysed descriptively. The research revealed that innoculation with tachyzoites 10

cyst was found on the 6
day of liver, in day

cyst was found on day 4

after infection, while in the control dosage there is no formation similar to cyst
found.
