Чувствительность к антибиотикам штаммов Bordetella bronchiseptica, выделенных от собак

Canine_Bordetella_bronchiseptica

У 78 штаммов  bronchiseptica, выделенных от , была изучена чувствительность к набору антибиотиков (энрофлоксацин, тетрациклин, доксициклин, ампициллин, триметоприм, амоксициллин/клавулановая кислота, сульфадиазин), определена минимальная ингибирующая концентрация.

The antimicrobial sensitivities of 78 (1995–1998) canine isolates of Bordetella bronchiseptica from 13 separate sources were determined. Minimum inhibitory concentrations were assessed using the E-test method or by agar dilution. All 78 isolates were sensitive to tetracycline, doxycycline, enrofloxacin, and amoxycillin/clavulanic acid; the majority were sensitive to ampicillin (63/78; 81%), trimethoprim (57/78; 73%), and sulphadiazine (63/78; 81%).

Plasmids in Bordetella bronchiseptica

Plasmids were detected in 14 out of the 24 isolates tested. There was no correlation between the presence of plasmids and antibiotic resistance, but there was some correlation between the presence of plasmids and the origin of the isolates. Three sizes of plasmid were found: 20, 14, and 5.5 kb. Eight of the isolates contained all three plasmids, the remainder one or two. Thirteen isolates demonstrated ß-haemolysis, of which six produced a soluble haemolysin. Except for one isolate, haemolysin production correlated with plasmid carriage.
