Influence of potential virulence determinants on Bordetella bronchiseptica-induced ciliostasis.
Eighteen strains of Bordetella bronchiseptica, selected on the basis of previously determined phenotypic characteristics, were examined for their ability to induce ciliostasis in canine tracheal outgrowth cultures. Fifteen strains grown on brucella agar caused ciliostasis. Strains that did not cause ciliostasis were stable, nonpiliated, and nonhemolytic, they did not produce extracellular adeny...
متن کاملBordetella bronchiseptica bronchitis.
The clinical course of a patient with bronchitis caused by Bordetella bronchiseptica is described. The organism was recovered on one occasion from a protected catheter brush specimen obtained at bronchoscopy and on two occasions from expectorated sputum specimens. The infection was eradicated with antimicrobial therapy.
متن کاملAirborne-induced experimental Bordetella bronchiseptica pneumonia in strain 13 guineapigs.
To evaluate the efficacy of a commercial bacterial vaccine in protecting Strain 13 guineapigs against fatal Bordetella bronchiseptica pneumonia, it was necessary to establish the infectivity and disease pathogenesis induced by virulent organisms. When guineapigs were exposed to small-particle aerosols of varying concentrations of virulent B. bronchiseptica, a spectrum of disease was produced th...
متن کاملAntimicrobial susceptibility of Bordetella avium and Bordetella bronchiseptica isolates.
Two veterinary pathogens, Bordetella bronchiseptica and Bordetella avium, were tested for their antimicrobial susceptibilities. Of the 20 antimicrobial agents tested, both species were consistently resistant to penicillin and cefuroxime but susceptible to mezlocillin, piperacillin, gentamicin, amikacin, and cefoperazone.
متن کاملExperimental infection of Bordetella bronchiseptica to rabbits.
Infectivity and pathogenicity of Bordetella bronchiseptica to rabbits were investigated by intranasal inoculation of the organism to suckling and young animals. Results are summarized as follows. 1. By inoculation of 5 X 10(4) and 10(6) organisms, the infection developed in 60% and 100% of young rabbits, respectively. 2. In young rabbits, the growth of the organism was evident in the trachea wi...
