Answer #1

E. Coli : Spreading

S. aureus : Beaded

Bacillus subtilis : spreading pattern

Justification

spreading is a pattern in which the organisms cover the entire surface of the slant.

Beaded pattern involves separate colonies

Filiform pattern is characterized by uniform lines

In general, Nonmotile bacteria usually produce even slants, while slightly motile to motile species produce irregular to spreading growth.

    One of the following bacteria is in a sample: Staphylococcus aureus, Citrobacter freundii, Bacillus subtilis, Proteus vulgaris and Enterococcus faecium. After Gram staining and visualization of the sample by brightfield microscopy, the identification of the bacterium was narrowed to two possibilities. An indole test was performed on the bacterium and produced a negative indole test result. This was enough information to determine the identity of the microorganism. Which microorganism was in the sample? (2 pts)
