Web6 dec. 2005 · We have extended the Codeço model to incorporate a state of hyperinfectivity (Figure 1 B). In this modified model, infections, I, are caused by ingesting water contaminated with B H HI vibrios per ml or B L non-HI vibrios per ml. Ingestion of HI vibrios occurs at the rate β H while ingestion of non-HI vibrios occurs at the rate β L. george cecil hodgsonWebHere, we demonstrate that passage of V. cholerae through the infant mouse intestine leads to an equivalent degree of hyperinfectivity as passage through the human host. We have used this infant mouse model of host-passaged hyperinfectivity to characterize the timing and the anatomic location of the competitive advantage of mouse-passaged V. cholerae … george cedarstrom plumbing
