ho’mi.nis. L. masc. n.homo man; L. gen. n. hominis of man. Cells are small, nonmotile, polymorphic rods with small capsules (Friis-Møller, 1981). The capsule is best developed on chocolate agar. On nutrient agar, cultures grow with capsulatedandnoncapsulatedvariants.Nogrowthisobservedon MacConkey agar and 7.5% salt agar. On 5% blood agar, colonies are 1.0 mm, grayish-white, and soft mucoid, without hemolysis after 24 h at 35∘C. After 24 h, the colonies are flatter, with concentric rings. Colonies are up to 2 mm on nutrient agar, and on chocolate agar are 1.5–2.5 mm and very mucoid. There is no CO2 or V-factor-requirement. Growth is very poor at 22∘C, and no growth is seen at 4∘C. In semisolid medium, colonies are facultatively anaerobic. Strains are CAMP negative and possess very strong alkaline and acid phosphatase and esterase (C4) activity, as shown by API ZYM tests. Nearly all strains have valine arylamidase and some α-fucosidase activity. All isolates have α-galactosidase and some α-glucosidase activity (Friis-Møller, 1981). Other biochemical characters are listed in Tables 2 and 3. Originally isolated from patients with chronic lung disease, but also isolated from cases of septicemia in hepatic
