Swarming gram negative rods
SpletINTRODUCTION There are four medically important gram-negative rods typically associated with the respiratory tract, namely, Haemophilus influenzae, Bordetella pertussis, Legionella pneumophila, and Acinetobacter baumannii ( Table 19–1 ). SpletProteus strains are able to grow in temperatures ranging from 10 to 43 °C. The optimal temperature for Proteus is 25 °C. The swarming occurs between 20 and 37 °C. Proteus spp. decompose organic substances. They also oxidatively deaminate amino acids, hydrolyze urea, exhibit proteolytic activity, and produce hemagglutinins and hemolysins.
