HAEMOPHILUS PARAINFLUENZAE
| Class: | Gamma Proteobacteria |
| Genus: | Haemophilus |
| Species: | Haemophilus parainfluenzae |
| Description: | Gram negative, pleomorphic rods, filamentous forms. Some strains possess capsule.Growth on chocolate agar is similar to that of H. parahaemolyticus: colonies are grayish white or yellowish opaque, 1-2 mm in diameter after 24h. Some strains produce flat, smooth colonies with entire edge, others show serrated edge and others produce rough wrinkled colonies. Growth in broth media may be granulated.Nonhemolytic (some strains show week beta-hemolysis, but the property is lost by subcultivation).Aerobic, facultatively anaerobic, require V-factor, but not X-factor for growth. CO2 is not required for growth. Growth on Mac Conkey agar is negative. |
