Mikrobiologi

19. august kl. 12:42 af beautyL - Niveau: Universitet/Videregående

A research group is studying a bactrium X that binds to muosal cells in the lungs and invades host cells. Wildtype X has an LD50 value of 10 bacteria when administered to mice by inhalation. Using transposon mutagenesis, the researchers have isolated two mutants of X that they call Xmut1 and Xmut2, both of which have LD50 values of 105 when inhaled by mice. However, in tissue culture cells, Xmut1 can invade the cells just as well as wildtype X, while Xmut2 cannot. Provide a possible explanation for these results. 

Håber nogen der lige kan give mig en forklare og et svar på det her. Det bare en normal opgave jeg lige gerne vil forstå.
