The effect of two protoporphyrin IX derivatives conjugated with single (PP[Lys(TFA)-OH)]2) or double (PP[Lys(TFA)-Lys(TFA)-OH]2) lysine moieties on the infectious capacity of Nosema ceranae spores was examined, and their efficacies were compared with those of a cationic porphyrin (H2TTMePP). Honeybees were inoculated with spores preincubated with porphyrins or with untreated spores (control). A significantly lower level of infection was observed in the bees infected with the porphyrin-treated spores than in the infected control. Por
