A Christmas Story. A Christmas Story is a 1983 American Metrocolor Christmas comedy film directed by Bob Clark, and based on Jean Shepherd's semi-fictional anecdotes in his 1966 book In God We Trust: All Others Pay Cash, with some elements from his 1971 book Wanda Hickey's Night of Golden Memories.
Bordetella is a genus of small (0.2 â 0.7 Âµm), Gram-negative coccobacilli of the phylum Proteobacteria. Bordetella species, with the exception of B. petrii, are obligate aerobes, as well as highly fastidious, or difficult to culture. All species can infect humans. The first three species to be described (B. pertussis, B. parapertussis, B. bronchiseptica,); are sometimes referred to as the 'classical species'.
There are currently eight species in the Bordetella genus. Three species in this genus are known to be pathogenic to humans. B. pertussis and B. parapertussis are very similar species. Both species cause pertussis (whooping cough) in humans and are separated merely by the toxins they release during infection.
