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.
متن کاملInfectious 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 ...
متن کاملPutative quantitative trait loci associated with the probability of contracting infectious bovine keratoconjunctivitis.
Infectious bovine keratoconjunctivitis, also known as pinkeye, is an economically important disease in cattle. The objective of this study was to detect QTL associated with infectious bovine keratoconjunctivitis in offspring from a Brahman x Hereford sire. The sire was mated to Hereford, Angus, and F1 cows to produce 288 offspring in 1994 and mated to MARC III ((1/4) Hereford, (1/4) Angus, (1/4...
متن کاملGenetic and environmental factors associated with incidence of infectious bovine keratoconjunctivitis in preweaned beef calves.
Infectious bovine keratoconjunctivitis (IBK) is one of the most economically important diseases in preweaned calves. This study examined the health records of 45,497 calves over a 20-yr period to determine environmental and genetic factors influencing the incidence of IBK. Three data sets were analyzed with an animal model. The first data set (n = 41,986) evaluated environmental factors and gen...
متن کاملA 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...
