Determination of Giardia lamblia cyst infective dose for the Mongolian gerbil (Meriones unguiculatus).

Cultivation of Giardia duodenalis in Mongolian gerbils.

The Mongolian gerbil (Meriones unguiculatus) is susceptible to infection with Giardia duodenalis trophozoites. Each animal was orally infected with 0.5 ml Diamond's TYIS-33 culture medium containing 10(6) trophozoites. Cysts were then collected and concentrated by sucrose gradient centrifugation. G. duodenalis cysts were first observed in feces on day 5 post-infection. The characteristic of G. ...

Variable infectivity of human-derived Giardia lamblia cysts for Mongolian gerbils (Meriones unguiculatus).

To determine whether gerbils can be used as a suitable animal model for giardiasis, we attempted to infect Mongolian gerbils with cysts of Giardia lamblia isolated from the stools of 10 humans with symptomatic and asymptomatic giardiasis. We obtained 100% infection with one isolate (CDC:0284:1), as evidenced by the presence of numerous trophozoites in the intestines of the gerbil and cysts in t...

The Effect of Diethylcarbamazine on Microfilariae of Brugia pahangi in Mongolian Jirds (Meriones unguiculatus)

Diethylcarbamazine (DEC) was effective in reducing microfilarial densities of Brugia pahangi in Mongolian jirds (Meriones unguiculatus) when it was administered intraperitoneally at the daily dosage of 300 mg/kg of body weight either for 5 consecutive days or every 3 days for 43 days with the total of 15 doses. The latter treatment scheme seemed to be more effective than the former, suggesting ...
