IFNG and Salmonella Infections: Thus, inadequate IFN-γ production in Salmonella infections as a result of Ascaris infection as seen in the current study would potentially antagonize the protective host immunity against Salmonella. In concordance with the Ascaris-induced impairment of NK cell functionality, the coinfected pigs had higher live Salmonella burdens compared to the Salmonella-single-infected group15, though the mechanistic link with NK cells functionality calls for further investigation.
