Moraxella bovis pathogenicity: An update
Comparative Immunology, Microbiology and Infectious Diseases, 2008Moraxella bovis is the etiologic agent of infectious bovine keratoconjunctivitis, the most important ocular disease affecting cattle worldwide. The severity of the cases varied from eyes that exhibited mild signs to severe clinical cases with profuse lacrimation, conjunctival swelling, corneal opacity, and ulceration.

Immunogenicity of Moraxella bovis hemolysin
American Journal of Veterinary Research, 1985SUMMARY Anti-Moraxella bovis hemolysin activity was observed in 35 cattle exposed to field infections of infectious bovine keratoconjunctivitis (ibk). All cattle in infected herds seroconverted with respect to antihemolysin whether or not clinical ibk was noted.

Partial characterization of a Moraxella bovis cytolysin
Veterinary Microbiology, 1995Moraxella bovis (M. bovis) is the etiologic agent of infectious bovine keratoconjunctivitis and M. bovis hemolysin is believed to be an important virulence factor. Two strains of M. bovis were compared, Epp 63(300) (Epp), a known virulent and hemolytic strain, and IBH 63 (IBH), a known avirulent and nonhemolytic strain.

Production and Characterization of Moraxella bovis Hemolysin
American Journal of Veterinary Research, 1977SUMMARY Moraxella bovis hemolysin was produced in trypticase soy broth and maximum hemolytic activity of the culture was observed during the logarithmic phase of growth. The hemolysin was filterable through a 0.22-μm (apd) membrane filter, heat labile, and destroyed by treatment with formalin or trypsin.

Biological reactivity of Moraxella bovis lipopolysaccharide
American Journal of Veterinary Research, 1990SUMMARY Lipopolysaccharide (lps) was isolated from Moraxella bovis 118F and ATCC 10900, M ovis ATCC 33078, and M phenylpyruvica ATCC 23333 by hot phenol-water extraction. In silver-stained sodium dodecyl sulfate polyacrylamide electrophoresis gels, M bovis 118F lps had a smooth profile, whereas the other Moraxella preparations appeared to be rough. The

A unified serotyping scheme for Moraxella bovis
Veterinary Microbiology, 1991Fifty-three Australian, seven British, two American and two New Zealand isolates of Moraxella bovis were classified into seven serogroups on the basis of their variable fimbrial (pilus) antigens using whole cell slide agglutination (SA), enzyme-linked immunosorbent assays (ELISA) and tandem-crossed immunoelectrophoresis (TCIE).

Plasmid profiles of Moraxella bovis isolates
American Journal of Veterinary Research, 1986SUMMARY Two-hundred isolates of Moraxella bovis were selected at random and examined for the presence of plasmid DNA by a rapid alkaline-detergent lysis method. All isolates contained from 1 to 6 plasmids, with varying agarose-gel electrophoretic migration patterns.

Growth requirements for Moraxella bovis
Veterinary Microbiology, 1984Moraxella bovis isolates do not necessarily require complex growth media. Minimal growth requirements were approached by selecting mutants that grew on progressively simpler solid media. Isolate 137T was selected until it could be cultured on a medium containing sodium L-glutamate, with thiamine, nicotinamide, pyridoxine and inorganic salts.

Identification of a capsular polysaccharide from Moraxella bovis
Carbohydrate Research, 2005The bacterium Moraxella bovis is the causative agent of an economically important disease of cattle: Infectious Bovine Keratoconjunctivitis (IBK), otherwise known as pinkeye. Little is known regarding the structure of the carbohydrates produced by M. bovis. The structure of a capsular polysaccharide from M. bovis (strain Mb25) has been determined using

Shunt nephritis associated with Moraxella bovis
Acta Paediatrica, 1996Moraxella bovis was repeatedly isolated from cerebrospinal fluid in a girl with two episodes of shunt nephritis. Clinical remission of nephritis was achieved only after shunt replacement. A list of about 20 infectious agents reported to date in patients with shunt nephritis is given. M.
