Damage to the sarcolemma is a consequence of fungal
infection and not specifically associated with the death grip. Damage to muscle cell sarcolemma is evident in both O. kimflemingiae- (A) and Beauvaria
bassiana- (B) infected muscle (arrows) (SEM images). Scale bars: A, 10 µm; B, 20 µm. Ophiocordyceps kimflemingiae-infected ants: controls, n=3; infected, n=6; B. bassiana-infected ants: controls, n=3; infected, n=3.
