Bordetella pertussis know which antibody has been detected. The organism is oxidase positive, but urease, nitrate reductase, and citrate negative. It is also not motile. Bordetella pertussis Bordetella pertussis is a Gram-negative, aerobic, pathogenic, encapsulated coccobacillus of the genus "Bordetella", and the causative agent of pertussis or whooping cough. Unlike "B. bronchiseptica", "B. pertussis" is not motile. Its virulence factors include pertussis toxin, filamentous hæmagglutinin, pertactin, fimbria, and tracheal cytotoxin. The bacterium is spread by airborne droplets; its incubation period is 9–10 days on average (range 6–20 days). Humans are the only known reservoir for "B. pertussis".

Unverricht–Lundborg disease ULD, MRIs taken once the disease has progressed show characteristic damage, which may help to correct a misdiagnosis. While ULD is a rare disease, the lack of well defined cases to study and the difficulty in confirming diagnosis provide strong evidence that this disease is likely under diagnosed. Unverricht–Lundborg disease is also known as EPM1, as it is a form of progressive myoclonic epilepsy (PME). Other progressive myoclonic epilepsies include myoclonus epilepsy and ragged red fibers (MERRF syndrome), Lafora disease (EPM2a or EMP2b), Neuronal ceroid lipofuscinosis (NCL) and sialidosis. Progressive myoclonic epilepsies generally constitute only a small percentage of epilepsy
