HAEMOPHILUS PARAHAEMOLYTICUS
| Class: | Gamma Proteobacteria |
| Genus: | Haemophilus |
| Species: | Haemophilus parahaemolyticus |
| Description: | Gram negative pleomorphic rods , filamentous forms.Growth on chocolate agar is similar to that of H. parainfluenzae: colonies are grayish white or yellowish opaque, 1-2 mm in diameter after 24 h. Some strains produce flat,smooth colonies with entire edge, others show serrated edge and others produce rough wrinkled colonies. Beta-hemolytic.Aerobic, facultatively anaerobic, require V-factor but not X-factor for growth. CO2 not required for growth. Growth on Mac Conkey agar is negative. |

| Pathogenicity: | Produce an extracellular IgA1 protease related to the H. influenzae endopeptidase, which cleaving human IgA1.Has been associated with acute pharyngitis, purulent oral infections, endocarditis, and exacerbation of chronic lower respiratory tract infections. |
