Coccobacilli – A coccobacillus (plural coccobacilli) refers to an intermediate shape between coccus (spherical) and bacillus (elongated). Coccobacilli rods are short and wide and may resemble cocci on a Gram stain.

X and V factor disks: Species of Haemophilus require either or both of the two factors for growth and can be used to differentiate the species. The X factor is haemin and the V factor is nicotinamide adenine dinucleotide (NAD). The factors are incorporated into filter paper disks which are placed on a blood free medium previously inoculated with the organism under test. After incubation, the presence or absence of growth around the disks indicates a requirement for that particular factor.

Gram stain: The Gram stain, is a laboratory staining technique that distinguishes between two groups of bacteria that have differences in the structure of their cell walls. Standard bacterial taxonomy makes a distinction between Gram-negative bacteria, which stain red/pink and the Gram-positive bacteria, which stain blue/purple. Different antimicrobial agents are directed specifically at gram-positive bacteria and gram-negative bacteria.
Choc: Chocolate agar is a non-selective, enriched growth medium. It is a variant of the blood agar plate. It contains red blood cells, which have been lysed by heating. Chocolate agar is used for growing fastidious (hard to grow) bacteria.
X and V factor disks: Species of Haemophilus require either or both of the two factors for growth and can be used to differentiate the species. The X factor is haemin and the V factor is nicotinamide adenine dinucleotide (NAD). The factors are incorporated into filter paper disks which are placed on a blood free medium previously inoculated with the organism under test. After incubation, the presence or absence of growth around the disks indicates a requirement for that particular factor. 
Mueller-Hinton: This is a culture medium that is commonly used for antibiotic susceptibility testing.
BAP or SBA: An abbreviation for blood agar plate or sheep blood agar. Blood agar contains mammalian blood (usually sheep, rabbit or horse), typically at a concentration of 5-10%. Blood agar is an enriched media used to isolate bacteria and to detect hemolytic activity.

Grows well on chocolate agar

Smells like mice or mild bleach

Requires X (hemin) and V (NAD)

Grows on BAP next to streak of Staph aureus

Grows on Mueller-Hinton with XV factor disk

Haemophilus influenzae

Chocolate agar for isolation; does not grow on BAP without V factor added
