  • Sample Question
    A 1-year-old toddler is admitted to the hospital in February following an abrupt onset of vomiting followed by watery diarrhea accompanied by low-grade fever. On admission, the child appears somnolent, has a fever of 38.8C (101.8F). His pulse is 130/min, respiratory rate 36/min, blood pressure 100/60 mmHg, and decreased skin turgor. Blood tests reveal an elevated white blood cell count (15,000/L) with 75% polymorphonuclear leukocytes. A stool sample is sent to the microbiology lab for analysis. Results reveal watery stools with no mucus, blood, leukocytes or parasites. A rapid antigen test is positive for a naked, segmented, dsRNA virus, so no stool culture is required. The diarrhea suffered by this child can be partially attributed to a viral protein (rotavirus NSP4) that alters the permeability of intestinal epithelial cell tight junctions and inhibits the glucose-coupled Na+ transport of these same cells, thereby increasing osmotic gap. What best describes this virulence mechanism?
