  • General information

    • the following information is not yet verified
      Family: Veillonellaceae

      Natural habitats
      Is widely distributed in the oral, genitourinary, respiratory, and intestinal biotas of humans and animals.

      Clinical significance
      Veionella species strains are frequently isolated from clinical specimens in aerobic-anaerobic polymicrobial cultures.
      Rarely, Veillonella species have been the only etiologic agents identified in serious infections such as meningitis, osteomyelitis, prosthetic joint infection, pleuropulmonary infection, endocarditis, and bacteremia.

      The prevalence of these organisms as pathogens is clearly increasing.
