Effect of E. granulosus infection on OVA-induced eosinophil recruitment and airway hyperresponsiveness. Samples collected from the BALF (A), blood (B) and PECs (C) of mice sensitized and challenged 24 h after the last OVA challenge(n = 5). The enhanced pause (Penh) was evaluated at baseline and after treatment with increasing doses of aerosolized methacholine (0–50 mg/ml). *, significant difference from OVA group, p <0.05 (D). OVA, ovalbumin; BALF, bronchoalveolar lavage fluid; PECs, peritoneal exudate cells; control, PBS control group; Eg, E. granulosus infection group; Eg + OVA, E. granulosu infection plus OVA-induced asthmatic group; OVA ,OVA-induced asthmatic group. *p <0.05; **p <0.01.
