IFNG and infection: Although this increased prevalence might be attributed to a higher rate of L. infantum infection, this study found similar rates of infection between the two groups (91.11% of Ibizan hounds and 75.56% of other breed dogs), as defined by a positive result for at least one of the four associated tests (i.e. L. infantum ELISA, L. infantum qPCR of blood, IFN-γ assay, or LST).
