Bacteria form complex and highly elaborate surface adherent communities known as biofilms which are held together by a self-produced extracellular matrix. We have previously shown that by adopting a biofilm mode of existence in vivo, the gram negative bacterial pathogens Bordetella bronchiseptica and Bordetella pertussis are able to efficiently colonize and persist in the mammalian respiratory ...
results the results showed that all the strains had the dominant allele ptxs1a. there were differences between the alleles of the clinical strains and the vaccine strain. conclusions in recent years, a significant increase in the incidence of pertussis has been reported worldwide. our findings regarding the allelic shift of the ptxs1 gene are similar to those reported in many european and ameri...
conclusions although previous studies have shown that a-g transition mutations in 23 srrna gene (domain v) are the main reason for the occurrence of high level macrolides resistance in b. pertussis, however, the mentioned single nucleotide polymorphisms (snps) have not been detected in our resistant strain. this is the first report of high level macrolide resistant b. pertussis, without snps in...
UNLABELLED Bordetella fimbriae (FIM) are generally considered to function as adhesins despite a lack of experimental evidence supporting this conclusion for Bordetella pertussis and evidence against a requirement for FIM in adherence of Bordetella bronchiseptica to mammalian cell lines. Using B. bronchiseptica and mice, we developed an in vivo adherence assay that revealed that FIM do function ...
We have previously reported that the respiratory pathogen Bordetella bronchiseptica can form biofilms in vitro. In this report, we demonstrate the disruption of B. bronchiseptica biofilms by rhamnolipids secreted from Pseudomonas aeruginosa. This suggests that biosurfactants such as rhamnolipids may be utilized as antimicrobial agents for removing Bordetella biofilms.
Bordetella bronchiseptica colonizes the respiratory tracts of a wide variety of mammals and causes a range of diseases, from lethal pneumonia to asymptomatic chronic infection. We report the complete genome sequence of Bordetella bronchiseptica strain S798, isolated from a pig with atrophic rhinitis in Japan.
Current methods for the isolation and identification of Bordetella bronchiseptica from clinical samples are time-consuming and are based, in part, on subjective observations. We describe the use of a Bordetella-specific DNA probe in a nonradioactive colony lift-hybridization assay for the identification of B. bronchiseptica. Eleven of 82 clinical specimens were found to contain B. bronchiseptic...
We present the scaffolded genome of Bordetella bronchiseptica ATCC 10580, assembled into 98 contigs. This 5.1-Mb assembly (68.2% G+C content) contains 4,870 coding regions. The strain was originally isolated from canine lung tissue and is used in quality control testing.
Bordetella bronchiseptica swine isolate KM22 has been used in experimental infections of swine as a model of clinical B. bronchiseptica infections within swine herds and to study host-to-host transmission. Here we report the draft genome sequence of KM22.
