FRANCISELLA PHILOMIRAGIA
| Class: | Gamma Proteobacteria |
| Genus: | Francisella |
| Species: | Francisella philomiragia |
| Description: | Gram-negative, catalase-positive, halophilic, aerobic, nonmotile, small coccoid bacterium.Colonies are semitranslucent,smooth,glossy,punctate to 0.5 mm in diameter, with entire edges after 24 h. Cells do not appear quite as small as those of F. tularensis. |
| Synonyms: | |
| Source: | Isolated from water, muskrats,and humans. |
| Pathogenicity: | Eighty-six percent of persons infected with F. Philomiiragia had an underlying immunosuppressive illness or near-drowning, while such persons constituted a minority of those with tularemia, suggesting that F. Tularensis is the more virulent pathogen. Nevertheless, infection with F. Philomiragia resulted in the death Of 1 of the 14 patients and clinical illness, including pneumonia And bacteremia without a known source, in most of the remaining patients. |
