Synonyms: Bisgaard taxon 2, Actinobacillus salpingitidis (Kohlert 1968) Mraz, Vladik and Bohacek 1976.
Gram-negative, coccobacilli, 0.4-2.0 μm, with a tendency for bipolar staining. Longer polymorphic rods and curved filaments occur
Cells appear individually, in pairs, and in short or long chains. Nonmotile.
Colonies are 0.1-1.0 mm in diameter. Facultatively anaerobic. Growth on MacConkey
agar is positive after 48 hours. Hemolysis on sheep blood agar is positive. Optimum
temperature is 37 ºC.
Isolated from the respiratory tract and oviduct of clinically healthy domestic fowl. It is a comensal in the respiratory tract and oviduct of
Isolated from salpingo-peritonitis in hens and from organs of dead chicks and young turkeys. Independent infections arise on the
basis of previous weakening; the others are of mixed or secondary character (mycoplasmosis, tuberculosis, leukocytosis, parasitic
Is pathogenic for 5-day-old chicks and for white mice. Guinea pigs and rabbits are not susceptible.
