Actinobacillus

A genus of gram-negative, immotile and nonspore-forming, oval to rod-shaped, often pleomorphic bacteria which occur as parasites or pathogens in mammals (including humans), birds, and reptiles. They are facultatively aerobic, capable of fermenting carbohydrates (without production of gas) and of reducing nitrates. The genomic DNA contains between 40 and 47 mol % guanine plus cytosine. The actinobacillus group shares many biological properties with the genus Pasteurella. See Pasteurella

Actinobacillus (Pasteurella) ureae and A. hominis occur in the respiratory tract of healthy humans and may be involved in the pathogenesis of sinusitis, bronchopneumonia, pleural empyema, and meningitis. Actinobacillus actinomycetemcomitans occurs in the human oral microflora, and together with anaerobic or capnophilic organisms may cause endocarditis and suppurative lesions in the upper alimentary tract. Actinobacilli are susceptible to most antibiotics of the β-lactam family, aminoglycosides, tetracyclines, chloramphenicol, and many other antibacterial chemotherapeutics.

Actinobacillus

[‚ak·tə·nō·bə′sil·əs] (microbiology) A species of gram-negative, oval, spherical, or rod-shaped bacteria that are of uncertain affiliation; coccal and bacillary cells are often interspersed, giving a “Morse code” form; species are pathogens of animals, occasionally of humans.

Actinobacillus

[ak″tĭ-no-bah-sil´us] a genus of gram-negative, nonmotile, coccoid or rod-shaped bacteria that are part of the normal microflora of mammals. The organisms are capable of infecting cattle and other domestic animals and, rarely, are associated with human infection; A. ligniere´sii is the causative agent of actinobacillosis.

Actinobacillus

(ak'tin-ō-bă-sil'lŭs), A genus of small, nonmotile, non-spore-forming, aerobic, facultatively anaerobic bacteria containing gram-negative rods interspersed with coccal elements. The metabolism of these bacteria is fermentative. They are pathogenic to animals. The type species is Actinobacillus lignieresii. [actino- + L. bacillus, a little rod]

Ac·ti·no·ba·cil·lus

(ak'tin-ō-bă-sil'ŭs) A genus of nonmotile, non-spore-forming, aerobic, facultatively anaerobic bacteria (family Brucellaceae) containing gram-negative rods interspersed with coccal elements. The metabolism of these bacteria is fermentative. They are pathogenic to animals. The type species is A. lignieresii. [actino- + L. bacillus, a little rod]
