What Dr. Humber said:

"Salmonella. Bacterium, a flagellated bacillus, Gram-negative, over 2200 known serovars."

Dr. Jessie's translation:

"Salmonella is a bacterium. In appearance, it’s pill-shaped, and has little hairs on it called flagella. If you put Gram stain on it, it looks pink. There are over 2200 different serological varieties of the Salmonella species."
