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 .
Pertussis toxin (PT) is a protein-based AB 5-type exotoxin produced by the bacterium Bordetella pertussis, [2] which causes whooping cough.PT is involved in the colonization of the respiratory tract and the establishment of infection. [3]
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. All species can infect humans.
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.

The WHO says that the only contraindication to either whole cell or acellular pertussis vaccines is an anaphylactic reaction to a previous dose of pertussis vaccine, [1] while the US Centers for Disease Control and Prevention (CDC) lists encephalopathy not due to another identifiable cause occurring within seven days after a previous dose of ...
In late 2022, together with the H3N2 strain of canine influenza and other respiratory pathogens, Bordetella bronchiseptica experienced a surge in canine infections. This was partially due to increased human travel and reopened offices following the relaxation of COVID-19 pandemic public health measures, leading to large numbers of dogs being ...
