Gram-negative, small, rod-shaped, pleomorphic depending on the growth medium, bipolar staining occasionally. Non-motile.
Non-sporulated.
Non-sporulated.
Sticky colonies. Growth is best on medium containing blood or serum. Hemolysis is present on sheep blood agar. Optimum
temperature 37 ºC, range 20-40 ºC. Growth on MacConkey agar is positive. V-factor independent.

Occurs infrequently in the nose of healthy humans.
Occasionally causes ozaena and other infections in the respiratory tract. Is a rare isolate from human bacteremia, endocarditis,
meningitis, bone-marrow infection, conjunctivitis, otitis media and peritonitis.
