The present study was designed to determine if an oral live Bordetella bronchiseptica vaccine protects dogs from developing signs of respiratory disease after challenge with virulent Bordetella bronchiseptica. The study was also designed to compare the level of protection induced by the oral vaccine with the protection provided by an intranasal live vaccine and an injected killed vaccine. Forty...

Bacteria of the genus Bordetella adhere preferentially to ciliated respiratory epithelial cells. We investigated the specificity of this unique tropism by assessing the concentration-dependent adherence of the three Bordetella species to ciliated cells from different hosts. Bordetella pertussis and Bordetella parapertussis adhere better to human ciliated cells than to those from rabbits, mice, ...

We report the prevalence in Bordetella bronchiseptica of IS481, a frequent target for diagnosis of Bordetella pertussis, as approximately 5%. However, PCR amplicons of the predicted size were detectable in 78% of IS481-negative strains. Our results suggest that PCR targeting IS481 may not be sufficiently specific for reliable identification of B. pertussis.

The differentiation of Bordetella species, particularly those causing human infection, is problematic. We found that sequence analysis of an internal fragment of nrdA allowed differentiation of the currently named Bordetella species. Analysis of 107 "Bordetella" isolates recovered almost exclusively from human respiratory tract specimens identified several putative novel species.

The genus Bordetella is reportedly a human or animal pathogen and environmental microbe. We report the draft genome sequence of Bordetella trematum strain HR18, which was isolated from the rumen of Korean native cattle (Hanwoo; Bos taurus coreanae). It is the first genome sequence of a Bordetella sp. isolated from the rumen of cattle.

Members of the genus Bordetella include human and animal pathogens that cause a variety of respiratory infections, including whooping cough in humans. Despite the long known ability to switch between a within-animal and an extra-host lifestyle under laboratory growth conditions, no extra-host niches of pathogenic Bordetella species have been defined. To better understand the distribution of Bor...

Guidance and protocol for the use of real-time PCR in laboratory diagnosis of human infection with Bordetella pertussis or Bordetella parapertussis

Bordetella pertussis and Bordetella bronchiseptica are respiratory pathogens of humans and animals respectively. Unlike many bacteria, they are able to efficiently colonise healthy ciliated respiratory mucosa. This characteristic of Bordetella spp. can potentially be exploited to develop efficient live vaccines and vectors for delivery of heterologous antigens to the respiratory tract. Here we ...

background and aims: pertussis is a highly contagious, vaccine-preventable disease. determination of the seroepidemiology of pertussis makes possible the evaluation of pertussis immunity in a population. in this study, we determined the seroprevalence of bordetella pertussis igg antibodies in different age groups in tehran, iran. materials and methods: overall, 1101 subjects between ages of 8 ...
