Lead (Pb), Cadmium (Cd) and Mercury (Hg) are recognized for their deleterious effect on the environment and immunity where subsequently compromised immune response affects the susceptibility to the potential parasitic infections. This study examined the host cytokine response after heavy metal intoxication (Pb, Cd, and Hg) and subsequent Ascaris suum infection in BALB/c mice. Pb modulated murine immune response towards the Th2 type of response (delineated by IL-5 and IL-10 cytokine production) what was also dominant for the outcome of A. suum infection. Chronic intoxication with Pb caused a more intensive development of the parasite infection. Cd stimulated the Th1 immune response what was associated with increase in IFN-γ production and reduction of larvae present in the liver of intoxicated mice. The larval burden was also low in mice intoxicated with Hg. This was probably not related to the biased Th1/Th2 type of immune response, but rather to the bad host conditions caused by mercury toxicity and high level of pro-cachectic cytokine TNF-α.
