Bordetella pertussis is a Gram-negative, aerobic, pathogenic, encapsulated coccobacillus bacterium of the genus Bordetella, and the causative agent of pertussis or whooping cough. Its virulence factors include pertussis toxin , adenylate cyclase toxin , filamentous haemagglutinin , pertactin , fimbria , and tracheal cytotoxin .
Bordetella (/ ˌ b ɔːr d ə ˈ t ɛ l ə /) is a genus of small (0.2 – 0.7 μm), Gram-negative, coccobacilli bacteria of the phylum Pseudomonadota. Bordetella species, with the exception of B. petrii, are obligate aerobes, as well as highly fastidious, or difficult to culture.

Whooping cough (/ ˈ h uː p ɪ ŋ / or / ˈ w uː p ɪ ŋ /), also known as pertussis or the 100-day cough, is a highly contagious, vaccine-preventable bacterial disease. [1] [10] Initial symptoms are usually similar to those of the common cold with a runny nose, fever, and mild cough, but these are followed by two or three months of severe coughing fits. [1]

Adenylate cyclase toxin from Bordetella pertussis is a 1706 amino acid residue long protein.The protein consists of three domains: from the N-terminus up to roughly residue 400, there is an adenylate-cyclase domain; between residues 500 and 700, there is a hydrophobic domain; and from residue 1000 to the C-terminus, there are calcium binding repeats.
Bordetella parapertussis is a small Gram-negative bacterium of the genus Bordetella that is adapted to colonise the mammalian respiratory tract. [1] Pertussis caused by B. parapertussis manifests with similar symptoms to B. pertussis -derived disease, but in general tends to be less severe. [ 2 ]
