Serum levels of SAA and MPO were increased in animals that received a protein-deficient diet before (4544 ± 644.3pg/ml and 784 ± 47.62μg/ml) and after infection (4792 ± 309.5 and 742.1 ± 55.11) when compared to the uninfected nourished mice (2526 ± 258.1pg/ml and 527.5 ± 70.86μg/ml) (Fig. 2A and 2B). Here, MPO is linked to infection.
