Vibrios are microbiologically characterized as gram-negative, highly motile, facultative anaerobes (not requiring oxygen), with one to three whiplike flagella at one end.
Francisella tularensis is a highly infectious facultative intracellular pathogen that is considered a potential agent of bioterrorism.
F. tularensis is a highly virulent facultative intracellular bacterium, disseminating within host mononuclear phagocytes.
Francisella tularensis is a highly virulent facultative intracellular bacterium, disseminating in vivo mainly within host mononuclear phagocytes.
Francisella tularensis is a highly infectious facultative intracellular bacterium that can be transmitted between mammals by arthropod vectors.
Tularemia is a zoonotic disease caused by Francisella tularensis, a highly infectious, facultative intracellular, Gram-negative bacterium.
B. microti is a member of the genus Brucella within the Alphaproteobacteria, which consists of medically important highly pathogenic facultative intracellular bacteria.
F. tularensis is a highly contagious facultative intracellular pathogen and has infectious doses as low as 10 50 bacteria; it is transmitted by inhalation, direct contact with infected animals, or ingestion of contaminated water or food.
One such organism is Francisella tularensis, a highly virulent, gram-negative, facultative intracellular pathogen that is the causative agent of tularemia.
Conversely, C. violaceum is facultative anaerobic, highly versatile in its metabolism, and can be found abundantly in multiple ecosystems, including water and soil; and in tropical and subtropical regions [ 17].
