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".

Rh disease Rh disease Rh disease (also known as rhesus isoimmunisation, Rh (D) disease, rhesus incompatibility, rhesus disease, RhD hemolytic disease of the newborn, rhesus D hemolytic disease of the newborn or RhD HDN) is a type of hemolytic disease of the newborn (HDN). The disease ranges from mild to severe, and typically occurs only in some second or subsequent pregnancies of Rh negative women where the fetus's father is Rh positive, leading to a Rh+ pregnancy. During birth, the mother may be exposed to the infant's blood, and this causes the development of antibodies, which may affect the health of subsequent
