Hydrolytic enzymes of Moraxella bovis.
Certain strains of Moraxella bovis produce tissue-damaging enzymes which may initiate or potentiate infectious bovine keratoconjunctivitis. Thirteen reference strains of this species were characterized physiologically and screened for production of various enzymes by some conventional biochemical tests and the API ZYM system (Analytab Products, Plainview, N.Y.). All 13 strains were hemolytic. A...
متن کاملDefined medium for Moraxella bovis.
A defined medium (medium MB) for Moraxella bovis was formulated. Nineteen strains grew well on medium MB. One strain was auxotrophic for asparagine, and another was auxotrophic for methionine. Strains of M. equi and M. lacunata also grew on medium MB. All strains had an absolute requirement for thiamine and were stimulated by or actually required the other growth factors in the medium.
متن کاملMolecular characterization of a secreted enzyme with phospholipase B activity from Moraxella bovis.
A candidate for a vaccine against infectious bovine keratoconjunctivitis (IBK) has been cloned and characterized from Moraxella bovis. The plb gene encodes a protein of 616 amino acids (molecular mass of ~65.8 kDa) that expresses phospholipase B activity. Amino acid sequence analysis revealed that PLB is a new member of the GDSL (Gly-Asp-Ser-Leu) family of lipolytic enzymes.
متن کاملPurification, characterization, and pathogenicity of Moraxella bovis pili
Pilins composed of the alpha or beta pilins of Moraxella bovis strain Epp63 were purified, subjected to chemical or enzymatic cleavage, and the resulting fragments sequenced by automated Edman degradation. alpha Pilin was found to be a 155-amino-acid polypeptide with a single intramolecular disulfide bridge. The beta pilin amino acid sequence substantiated the previously reported structure deri...
متن کاملCloning and sequencing of a Moraxella bovis pilin gene.
Moraxella bovis pili have been shown to play a major role in both infectivity and protective immunity of bovine infectious keratoconjunctivitis. Sonicated M. bovis DNA from the piliated strain EPP63 was inserted into the vector lambda gt11 with EcoRI linkers. Recombinant phage were screened with an oligonucleotide probe based on the amino-terminal portion of the DNA sequence of a Neisseria gono...
