Pertussis is caused by the bacterium Bordetella pertussis. It is an airborne disease (through droplets) that spreads easily through the coughs and sneezes of an infected person. Spread from other animals Uncertainties have existed of B. pertussis and<unk>  as a zoonotic disease since around 1910 but in the 1930s, knowledge was gained that the bacteria lost their virulent power when repeatedly spread on agar media. This explained the difficulties to reproduce results from different studies as the pre-inoculating handlings of the bacteria were not standardized among scientists. Today it is established that at least some primate species are highly susceptible to B. pertussis and develop clinical<unk>  in high incidence when exposed to low inoculation doses. The bacteria may be present in wild animal populations, but this is not confirmed by laboratory diagnosis, although<unk>  is known among wild gorillas. Several zoos also have a long-standing custom of vaccinating their primates against<unk> .
