The BvgAS phosphorelay regulates ∼10% of the annotated genomes of Bordetella pertussis and Bordetella bronchiseptica and controls their infectious cycles. The hierarchical organization of the regulatory network allows the integration of contextual signals to control all or specific subsets of BvgAS-regulated genes. Here, we characterize a regulatory node involving a type III secretion system (T...
Respiratory tract infections (RTIs) are a major public health concern. This study aims to investigate the profiles and epidemiological characteristics of acute RTIs respiratory pathogens in Palestinian hospitalized patients. Clinical samples from patients with symptoms admitted between January 2011 December 2016 were referred Central Public Health Laboratory (PHCL) identify causative pathogen. ...
Species of the genus Bordetella associate with various animal hosts, frequently causing respiratory disease. Bordetella pertussis is the primary agent of whooping cough and other Bordetella species can cause similar cough illness. Here, we report four complete genome sequences from isolates of different Bordetella species recovered from human respiratory infections.
No standardized PCR method is available for the laboratory diagnosis of the pertussis syndrome. Consensus recommendations for the use of PCR in the diagnosis of Bordetella pertussis infections have been proposed, and the aim of this study was to develop a method that fulfills all of these criteria. A rapid-cycle shared-primer PCR method with a microwell format and probe hybridization detection ...
A novel multitarget real-time PCR (RT-PCR) assay for the rapid identification of Bordetella pertussis, B. parapertussis, and B. holmesii was developed using multicopy insertion sequences (ISs) in combination with the pertussis toxin subunit S1 (ptxS1) singleplex assay. The RT-PCR targets for the multiplex assay include IS481, commonly found in B. pertussis and B. holmesii; IS1001 of B. parapert...
A serological study was undertaken to investigate infections in active-duty United States soldiers with illnesses characterized by prolonged, afebrile, nonproductive coughs. Fifty-four soldiers were enrolled with such illness of >/=2 weeks' duration (case patients) along with 55 well soldiers (control subjects). Serum samples were tested for IgG and IgA antibody to 3 Bordetella pertussis antige...
Histamine-sensitizing factors from microbial agents, with special reference to Bordetella pertussis.
