Figures & data

Figure 1. Survival curves of A. subterraneus subterraneus workers without bacterial biofilms (pre-treated with gentamicin) or with biofims (pre-treated with sterile distilled water) following exposure to the entomopathogenic fungus Metarhizium anisopliae. Error bars: SEM (Adapted from Mattoso et al., ref. Citation10)
