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...
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 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...
متن کاملLarge genomic differences between Moraxella bovoculi isolates acquired from the eyes of cattle with infectious bovine keratoconjunctivitis versus the deep nasopharynx of asymptomatic cattle.
Moraxella bovoculi is a recently described bacterium that is associated with infectious bovine keratoconjunctivitis (IBK) or "pinkeye" in cattle. In this study, closed circularized genomes were generated for seven M. bovoculi isolates: three that originated from the eyes of clinical IBK bovine cases and four from the deep nasopharynx of asymptomatic cattle. Isolates that originated from the eye...
متن کاملImproved semiselective medium for isolation of Legionella pneumophila from contaminated clinical and environmental specimens.
Eighteen types of media, all of which used charcoal yeast extract medium as a base, were tested for their ability to support the growth of a stock strain of Legionella pneumophila. Fifteen of these contained antimicrobial agents. Five antibiotic-containing media which performed best in growing the stock strain were then tested for the ability to grow L. pneumophila from clinical respiratory tra...
