[Aerobic bacterial flora of the nasal cavity of rabbits]

On the basis of bacteriological examinations carried out in April 1984 on 60 intranasal swabs, aerobic respiratory microbes were studied in rabbits. Differences in flora between animals with and without respiratory diseases were studied. Fourteen bacterial species were identified with no difference due to the pathological status. They were: Bordetella bronchiseptica, Staphylococcus epidermidis, Streptococcus faecalis, Pasteurella multocida, Staphylococcus aureus, Bacillus sp., Branhamella catarrhalis, Micrococcus sp., Enterobacter agglomerans, Proteus mirabilis, Pseudomonas paucimobilis, Pseudomonas diminuta, Alcaligenes faecalis and Escherichia coli. However, young weaned rabbits were more often Pasteurella carriers than adult females in maternity. The usefulness of performing only Pasteurella and Bordetella cultures in rabbits is questionable as is use of vaccines in order to prevent bacterial respiratory syndrome. It is emphasised that myxomatosis should be pursued in the investigation of respiratory infections in rabbit.
