To explain: The strain of Salmonella typhi that was inhibited most by CFTR mutation.
Concept introduction: Allele is the modification of the gene. Salmonella typhi is the causative bacteria of typhoid. Cystic fibrosis (CF) is a genetic disorder due to inability of the cell to perform endocytosis due to mutation in the CFTR gene. Cystic fibrosis affects the lungs, intestine, liver, and kidneys. Endocytosis is a phenomenon where the cell takes up molecules by engulfing with its membrane. The S. typhi exploits this mechanism to infect the intestinal cell and cause diarrhea. The cells that are homozygous for this CFTR mutation cannot perform endocytosis, and the S. typhi cannot infect those individuals.

She recently returned from a trip to sub-Saharan Africa, where she did not take malaria prophylaxis. On examination, she is febrile (39.8°C/103.6°F) and hypotensive. Laboratory studies reveal hemoglobin of 8.0 g/dL, platelet count of 50,000/μL, and evidence of hemoglobinuria. A peripheral blood smear shows ring forms and banana-shaped gametocytes.
