Some 20 babies in the U.S. die annually from the infection, per the CDC. ... called Bordetella parapertussis. Transmission occurs when an infected person coughs or sneezes, "and tiny drops ...
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 ]
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.
The first patient in the U.S. was hospitalized with "severe" bird flu. Here's what you should know about symptoms, according to an infectious disease expert.
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]
The CDC said the patient's sample showed mutations in the hemagglutinin (HA) gene, the part of the virus that plays a key role in it attaching to host cells. The mutations seen in the patient are ...
Bordetella parapertussis shows the most similarity to B. pertussis and was therefore used for research determining the role of PT in causing the typical symptoms of whooping cough. Rat studies showed the development of paroxysmal coughing, a characteristic for whooping cough, occurred in rats infected with B. pertussis .
