Medical Microbiology, 4th edition, [1] states that Regan-Lowe medium [2] (containing charcoal, blood, and antibiotic) has replaced Bordet–Gengou medium as the medium of choice for routine Bordetella pertussis incubation. Bordetella bacteria were difficult to culture; Jules Bordet and Octave Gengou invented the first version to isolate the ...
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 .
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]

A nasopharyngeal swab is a device used for collecting a sample of nasal secretions from the back of the nose and throat. [ 1 ] [ 2 ] The sample is then analyzed for the presence of organisms or other clinical markers for disease.
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]
Two of these (B. pertussis and B. bronchiseptica) are also motile. [3] [4] There are about 16 different species of Bordetella likely descending from ancestors who lived in soil and/or water environments. [5] B. pertussis and occasionally B. parapertussis cause pertussis (whooping cough) in humans, and some B. parapertussis strains only colonize ...
