Other Moraxella Species Other Moraxella species are occasional causes of a wide range of infections, including bronchitis, pneumonia, empyema, endocarditis, meningitis, conjunctivitis, endophthalmitis, urinary tract infection, septic arthritis, and wound infection. In a report on all Moraxella isolates submitted to the Centers for Disease Control and Prevention between 1953 and 1980, certain clinical associations were apparent (Table 138-2). M. osloensis and M. nonliquefaciens, the most commonly isolated species, were cultured from various normally sterile body sites, including blood, cerebrospinal fluid, and joints. M. osloensis was the Moraxella species most frequently isolated from blood; M. nonliquefaciens tended to be isolated.
