Research Abstract |
This study aims to understand the symbiosis between bacteria and protozoa in animal intestine. In this study, the new parasitic protozoa were detected from fecal sample of cattle. And then it was suggested that some viable intestinal bacteria selectively existed in the dormant protozoa, i.e. cyst condition, and these bacteria accounted for minor population in the whole feces. Some anaerobic intestinal bacteria maybe use the intestinal protozoa for a vehicle, and not only defend itself from oxygen at natural environment but also may watch for an opportunity to pass on to other hosts.
