We report a significantly higher prevalence of intestinal nematodes in patients with pulmonary tuberculosis (TB) compared to a matched control group: 33/57 (57.8%) in patients with TB and 18/86 (20.9%) in the control group; OR=5.19; 95% CI= 2.33-11.69; p=0.000). When TB patients eosinophilia was also significantly higher among those with intestinal parasites (69.8%) compared to those without this condition (45.6%). We hypothesized that the immune modulation induced by nematodes is a factor that enhances TB infection/progression and that eosinophilia seen in TB patients is a consequence of helminth infection.
