A haemolytic cell-free preparation ofMoraxella bovisconfers protection against infectious bovine keratoconjunctivitis

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...

Infectious Bovine Keratoconjunctivitis Management

Infectious bovine keratoconjunctivitis is a disease that affects many herds in the US, however, the epidemiology of the disease is complicated and control is frustrating for many producers. This article discusses putative causes of IBK and approaches to understanding the causes of success and apparent failure in IBK control programs.

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 ...
