Genetic control of the murine corneal response to Pseudomonas aeruginosa

Inbred mouse strains differ in susceptibility to intracorneal challenge with Pseudomonas aeruginosa. Genetic studies indicate that resistance to corneal infection is dominant over susceptibility and is controlled by autosomal genes, at least one of which is located outside of the H-2 locus. On the basis of genetic complementation studies, the susceptible strains BALB/c and C57BL/6 each bear one resistance gene, since the F1 hybrid (BALB/c X C57BL/6) was uniformly resistant to infection.
