Microfilariae and gravid females induces the formation of polyps on the visceral pleura. Lungs from 70 days Mfpos gerbils were recovered and polyps were analysed by histology. a Microfilaria (black arrow) in a small lung polyp. b Microfilaria (black arrow) in a small polyp of the diaphragm. Numerous eosinophils (lobed-shaped nucleus) near to microfilaria. c Microfilaria (black arrow) in a large lung polyp. d Linear regression between the pleural pathology and microfilaremia (Y (pleural pathology) = 0.02431 × X (microfilarial load) + 1.408; R2 = 0.67; n = 23 from 3 independent experiments). e Linear regression between the pleural pathology and gravid female (Y (pleural pathology) = 2.050 × X (number of gravid female) + 0.6341; R2 = 0.; n = 15 from 2 independent experiments)
