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.

Adenylate cyclase toxin (CyaA) is released from bacterium Bordetella pertussis by the T1SS (Type 1 secretion system) and released in the host’s respiratory tract in order to suppress its early innate and subsequent adaptive immune defense. [1] CyaA plays a particular role in the early phases of airway colonization.
The USDA animal safety list is located at 9 CFR Subchapter B. [4] Not all select agents require BSL-4 handling, namely select bacteria and toxins, but most select agent viruses do (with the notable exception of SARS-CoV-1 which can be handled in BSL3). Many non-select agent viruses are often handled in BSL-4 according to facility SOPs or when ...
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 ]
A single protein, VirB10 is integral in both the inner and outer membranes. It inserts into the outer membrane using an α-helical barrel structure which helps form a channel between the two membranes. [7] There is an opening on the cytoplasmic end of the channel which is followed by a large chamber and a second opening.
Bordetella bronchiseptica is a small, gram-negative, rod-shaped bacterium of the genus Bordetella. [1] It can cause infectious bronchitis in dogs and other animals, [ 2 ] but rarely infects humans. [ 3 ]
