- A clinical microbiologist is studying a microbe that can cause infections and gastrointestinal disease in humans, and which can also survive and reproduce in mice. A dormant cyst form of the microbe infects human hosts through fecal-oral transmission if they come in contact with mouse droppings and don’t wash their hands before eating. The organism grows in long filaments when grown at 20-28 deg C, and forms round/ovoid cells when grown at temperatures above 28 deg C. Sexual reproduction (fusion of haploid gametes) occurs in both humans and mice. A cell wall is present, and cells contain nuclei. This microbe could be which of the following? Bacterium Fungus Virus Protozoanarrow_forwardThis is a drawing of a Giardia cell.

How do the unique structural characteristics of mycoplasmas relate to their bacterial morphology? Mycoplasmas have a low G + C genome content. Mycoplasmas appear Gram negative when a Gram stain is performed. Mycoplasmas lack a cell wall. Mycoplasmas form colonies with a fried-egg appearance.arrow_forward
