A differential stain allows us to distinguish between different types of bacteria based on structural characteristics

The same catalase-positive, coagulase-positive, beta-hemolytic Gram positive coccus from the previous question was isolated from an infected finger wound.  Based on the most likely pathogen, the isolated organism _________ be considered a definitive pathogen, and ____________ grow on MacConkey agar.

You have cultures tubes of five organisms on your lab bench. However, the labels of the tubes have come off and you need to relabel the tubes correctly! First, you look up some of the various reactions for the organisms in question: genus gramreaction shape (morphology) catalasereaction glucosefermentation lactosefermentation phenylalaninedeaminase citrateutilization Bacillus + rod + + or – ? ? ? Staphylococcus + coccus + + ? ? ? Enterobacter – rod + + + – + Morganella – rod + + – + – Pseudomonas – rod + – – – ? What one specific laboratory procedure will provide results to differentiate Bacillus and Staphylococcus from each other and also from the remaining three genera?

All organisms in this picture SHOULD BE GRAM NEGATIVE. What most likely went wrong with the gram staining technique to produce this image?
