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 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 ]
Whooping cough is a highly contagious bacterial infection that affects children and adults alike - though it's more common and concerning in infants and toddlers. The infection primarily affects ...
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]
According to the Centers for Disease Control. whooping cough, also known as pertussis, is a highly contagious respiratory illness caused by the bacteria Bordetella pertussis. It spreads easily ...
Due to the fact B. pertussis is only found in humans and shows little genetic variation from the other Bordetella species, it is thought that it was derived from a common ancestor in recent years. B. parapertussis can affect both humans and other mammals, primarily sheep. Similar to B. pertussis, it causes whooping cough in babies. Yet, when ...
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.
