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.

Bordetella parapertussis can cause a milder form of pertussis. The bordetellae are small, Gram-negative, aerobic coccobacilli. Bordetella pertussis produces a number of virulence factors, including pertussis toxin, adenylate cyclase toxin, filamentous hemagglutinin, and hemolysin.

B. pertussis is a Gram-negative, pleomorphic aerobic coccobacillus that grows optimally on either Bordet-Gengou or Regan-Lowe agar between 35°C and 37°C and can be differentiated from other Bordetella species based on its growth and biochemical characteristics.

Bordetella is a Gram-negative, pleomorphic, aerobic coccobacillus. In the past several years, even countries with high immunization rates in early childhood have experienced rises in pertussis cases. Reasons for the resurgence of reported pertussis may include molecular changes in the organism and increased awareness and diagnostic capabilities ...

The majority of human illness is caused by Bordetella pertussis, and some is caused by Bordetella parapertussis. Bordetella is a Gram-negative, pleomorphic, aerobic coccobacillus. In the past several years, even countries with high immunization rates in early childhood have experienced rises in pertussis cases.

Bordetella pertussis is a contagious small gram-negative coccobacillus that is the causative organism associated with whooping cough. Pertussis infections are highly communicable and infected individuals continue to shed the bacteria for approximately 2-weeks after the distinctive whooping cough begins ( Halperin et al. 2018 ).

2018年5月1日 · Bordetella pertussis is a fastidious gram-negative coccobacillus responsible for the respiratory infection commonly known as “whooping cough.” The organism is spread by respiratory droplets and is highly contagious among close contacts.

Bordetella pertussis is a fastidious gram-negative coccobacillus responsible for the respiratory infection commonly known as “whooping cough. The organism is. spread by respiratory droplets and is highly contagious among close contacts. The typical incubation period is 7 to 10 days, but it may be as long as 21 days.

Bordetella pertussis is a small, aerobic, non-acid fast, slow-growing Gram-negative coccobacillus with fastidious growth requirements and has no known environmental or animal reservoir. It possesses several adhesins, toxins, and other virulence factors that contribute to disease (see Graphical abstract) some of which are included or targeted in ...
