What is your preliminary idea (s) of the species of bacteria responsible for anna's infection? has your idea changed since the last activity? explain your reasoning?

For Anna’s case, my preliminary idea of the species of bacteria responsible for Anna’s infection is a Gram-negative bacterium as observed in gross examination of the colony. With this, my idea has not changed since the last activity for the bacteria was rod-shaped when we view it through a microscope and the color of the colonies was pink after we Gram stained it, which indicate that it is Gram-negative.
