In vitro susceptibilities of Bordetella pertussis and Bordetella parapertussis to six new oral cephalosporins.
Of six new oral cephalosporins, cefixime and cefpodoxime were the most active (MIC for 90% of isolates tested [MIC90], 16 micrograms/ml) against Bordetella pertussis, followed by cefetamet, cefprozil, and loracarbef (LY163892) (MIC90, 64 micrograms/ml) and ceftibuten (MIC90, 128 micrograms/ml). Against Bordetella parapertussis, loracarbef was more active (MIC90, 32 micrograms/ml) than the other...
متن کاملPolymorphism of repeated regions of pertactin in Bordetella pertussis, Bordetella parapertussis, and Bordetella bronchiseptica.
Pertactin is an outer membrane protein expressed by Bordetella pertussis, Bordetella parapertussis, and Bordetella bronchiseptica that induces protective immunity to Bordetella infections. The immunodominant and immunoprotective epitopes of pertactin include two repeated regions, I and II. Comparison of these two repeated regions showed that B. parapertussis pertactin is invariant, whereas B. p...
متن کاملNucleotide sequence homology to pertussis toxin gene in Bordetella bronchiseptica and Bordetella parapertussis.
Multiple strains of Bordetella parapertussis and B. bronchiseptica were examined for the presence of nucleotide sequences which hybridized with a cloned 4.5-kilobase (kb) fragment of B. pertussis DNA containing the genes responsible for pertussis toxin expression. All six B. parapertussis strains tested had nucleic acid sequences that hybridized with the cloned 4.5-kb fragment in Southern blot ...
متن کاملRegulation of pertussis toxin and lipopolysaccharide levels of Bordetella pertussis 134 in response to modulators
Whooping cough (pertussis) is a highly contagious disease of the human respiratory tract, which is caused by Bordetella pertussis. Reemerge of pertussis in some highly immunized populations and divergency in gene order among several B. pertussis strains promoted this research to study the change of pertussis toxin (PT) and lipopolysacharide levels in response to the different environments. Th...
متن کاملInfection with Bordetella parapertussis but not Bordetella pertussis causes pertussis-like disease in older pigs.
The 3 major Bordetella species--namely, B. pertussis, B. parapertussis, and B. bronchiseptica--can be distinguished by their different host ranges. B. bronchiseptica infects a wide range of mammals (including humans), whereas B. pertussis infects only humans and, under experimental conditions, mice and pigs. In contrast, B. parapertussis, also a causative agent of pertussis, displays a unique h...
