A haemolytic cell-free preparation of Moraxella bovis confers protection against infectious bovine keratoconjunctivitis.

Protection conferred by a cell-free preparation from a haemolytic Moraxella bovis isolate, UQV 148NF, was compared to an equivalent fraction from a non-haemolytic M. bovis isolate, Gordon 26L3, and to a recombinant DNA-derived pili vaccine. Three groups of ten calves were vaccinated twice with one of the three preparations and, together with ten non-vaccinated calves, challenged with virulent M...

Semiselective medium for isolation of Moraxella bovis from cattle with infectious keratoconjunctivitis.

The incorporation of 2.5 micrograms/ml of cloxacillin into 5% bovine blood agar provided an inexpensive, easily prepared culture medium for the primary isolation of Moraxella bovis from bovine lacrimal and nasal secretions. With this medium, the time required to identify and isolate M. bovis from large numbers of field specimens was substantially reduced, whereas the sensitivity of isolation wa...

Dynamics of Moraxella bovis infection and humoral immune response to bovine herpes virus type 1 during a natural outbreak of infectious bovine keratoconjunctivitis in beef calves

Infectious bovine keratoconjunctivitis (IBK) is an acute disease caused by Moraxella bovis (Mb). Several factors may predispose animals to an IBK outbreak; one commonly observed is infection with bovine herpes virus type 1 (BHV-1). The aim of this study was to investigate the dynamics of BHV-1 virus infection and its relation with clinical cases of IBK in weaned calves from a beef herd with a h...

Infectious bovine keratoconjunctivitis antimicrobial therapy.

Infectious bovine keratoconjunctivitis (IBK) is one of the most common diseases of cattle and is of major economic importance. If the primary aetiological agent, Moraxella bovis, is successfully eliminated from ocular tissues corneal ulcers heal at a constant rate. If treatment is unsuccessful ulcer reoccurrence may follow initial healing. Appropriate antimicrobial selection requires knowledge ...
