ABSTRACT: Interleukin-12 receptor beta-1 (IL-12Rbeta1) defect is generally associated with selective susceptibility to weakly pathogenic mycobacteria and Salmonella species. Patients rarely experience infections caused by other organisms. We report a 5-year-old patient with IL-12Rbeta1 deficiency who developed recurrent visceral leishmaniasis 6 months apart. The patient responded to lyposomal amphotericin B treatment reasonably well.
