Association of a Pasteurella Haemolytica-Like Organism with Enteritis in Swine

Pasteurella haemolytica A2

Twenty-one healthy local goats of about eight months old were divided into four groups consisting of six animals in groups 1, 2 and 3 and three animals in group 4. Goats in groups 1 and 2 were inoculated intratracheally with Mycoplasma arginini. Goats in group 2 were inoculated again with Pasteurella haemolytica A2 six days later. Goats in group 3 were inoculated intratracheally with P. haemoly...

Lipopolysaccharide complexes with Pasteurella haemolytica leukotoxin.

The presence of lipopolysaccharide (LPS) in gram-negative bacterial repeats-in-toxin (RTX) toxin preparations, as well as the harsh conditions required to remove it, suggests that LPS may complex with RTX toxins. Concentrated culture supernatant (CCS) preparations of the RTX toxin Pasteurella haemolytica leukotoxin (LKT) contained LKT and LPS as the most prominent components, with LKT and LPS c...

Cultivation of Pasteurella haemolytica in a chemically defined medium.

A chemically defined medium was developed for the aerobic cultivation of Pasteurella haemolytica. Studies on the growth of strain H44L were conducted in a medium consisting of 15 amino acids, inorganic salts, citrate, nicotinamide, pantothenate, thiamine or thiamine monophosphate, and carbon sources. The amino acids were provided as l isomers, because racemic mixtures of some amino acids inhibi...
