An infectious disease research group is studying a microbe that can cause infections and gastrointestinal disease in humans, and which can also survive and reproduce in hamsters. A dormant cyst form of the microbe infects human hosts through fecal-oral transmission if they come in contact with hamster droppings and don’t wash their hands before eating. The organism exhibits active, motile morphological forms at other stages of its life cycle. Sexual reproduction (fusion of haploid gametes) occurs in the hamsters; only asexual reproduction occurs in humans. It has a nucleus, but does NOT have a cell wall. This microbe could be which of the following? Protozoan Fungus Bacterium Virus
