Blowfly strike and wool growth. 2. Potential mediators of effects, other than anorexia.

Abstract

Infection of 5 finewool Merino wethers (18 month old) with 500 Lucilia cuprina larvae from days 0-7 induced significant elevations in temperature and plasma cortisol, interleukin-6 (IL-6), bilirubin and a significant depression in plasma glucose. Uninfected control sheep pair fed with struck sheep (n=5) did not differ from uninfected controls (n=6). No significant effects were observed for plasma IL-1a, IL-8, tumour necrosis factor-a and leptin, although there was a trend towards lower leptin concentrations in fly struck sheep.
