豚由来Bordetella bronchiseptcaの化学療法剤に対する感受性

抄録

A total of 61 strains (including 1 strain of stock culture ATCC 4617) ofBordetella bronchisepticaisolated from swine were examined for sensitivity to 52 antibacterial drugs by means of a plate dilution method. Of them, 39 strains were derived from 35 pigs presenting clinical sighs of atrophic rhinitis and 21 strains from apparently healthy pigs.
The results obtained are summarized as follows. Many strains were highly sensitive to sulfa drugs, tetracyclines, colistin, polymyxin-B, and gentamicin.
Most of them were relatively sensitive to fradiomycin, erthromycin, kanamycin, chloramphenicol, novobiocin, and oxolinic acid.
Most of the strains tested were inclined to be decreasingly sensitive to aminobenzyl penicillin, oleandomycin, thiophenicol, bacitracin, streptomycin, macarbomycin, virginiamycin, spiramycin, tylosin, and mikamycin in the order listed. On the other hand, 11.5% of the strains tested were resistant to sulfa drugs and manifbsted a cross-resistance to aminobenzyl penicillin and streptomycin.
