Pertussis (Whooping Cough) & Pertussis Vaccine Pertussis, commonly referred to as whooping cough, is a highly contagious respiratory disease caused by the Bordetella (B.) pertussis bacterium. B. pertussis bacteria attach themselves to the mucus membranes of the respiratory tract and cause inflammation in the body.n severe cases of whooping cough disease, complications include high fever, brain inflammation, convulsions, pneumonia and death. Symptoms of B. pertussis at its onset are similar to the common cold, or an allergy attack with stuffy or runny nose, dry cough, loss of appetite, fatigue and, sometimes, a low fever.

Bordetella pertussis Previously called Alcaligenes fecalis. Bordetella bronchiseptica. a small, gram-negative, motile bacillus. A normal inhabitant of the respiratory tract in humans, dogs and pigs, but also causes pneumonia, stillbirths, abortions, canine infectious tracheobronchitis (see kennel cough) and atrophic rhinitis in pigs. pertussis produces various toxins including a dermo-necrotising toxin, an adenyl cyclase, an endotoxin and pertussis toxin, as well as surface components such as fimbrial haemagglutinin. Clinical findings. Runny nose, sneezing, mild cough, low-grade fever.

Test ID: BPRPBordetella pertussis and Bordetella parapertussis, Molecular Detection, PCR Bordetella pertussis is the highly contagious etiological agent of pertussis or whooping cough. Bordetella parapertussis causes a similar, but generally less severe illness. Despite vaccination efforts, Bordetella pertussis remains common in the United States, underscoring the need for effective diagnostic tests. In the United States, pertussis is most common in the late summer months.

- 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.

Whooping Cough: What You Need to Know What do we all need to know about whooping cough (pertussis)? WebMD asked epidemiologist Tom Clark, MD, MPH, of the CDC's National Center for Immunization and Respiratory Diseases. What is whooping cough?

Whooping cough Whooping cough (pertussis) is a very contagious respiratory infection caused by the bacterium Bordetella pertussis. The major symptom of whooping cough is the characteristic cough, which is often followed by a 'whooping' sound on inhalation. One in every 200 babies who contract whooping cough will die. Immunisation is the best way to reduce the risk of whooping cough.

Bordetella pertussis Bordetella pertussis is a small, Gram-negative, coccoid bacterium about the size of 0.8 µm by 0.4 µm. It is an encapsulated immotile aerobe that does not make spores. Bordetella pertussis produces a number of virulence factors, including pertussis toxin, adenylate cyclase toxin, filamentous hemagglutinin, and hemolysin.

- Bordetella pertussis is a Gram-negative, aerobic coccobacillus capsulate of the genus Bordetella, and the causative agent of pertussis or whooping cough.Unlike B. bronchiseptica, B. pertussis is not motile.. pertussis has the ability to inhibit the function of the host's immune system. The toxin, known as pertussis toxin (or PTx), inhibits G protein coupling that regulates an adenylate cyclase-mediated conversion of ATP to cyclic AMP.

- Causes. Pertussis, a respiratory illness commonly known as whooping cough, is a very contagious disease caused by a type of bacteria called Bordetella pertussis.These bacteria attach to the cilia (tiny, hair-like extensions) that line part of the upper respiratory system.hile pertussis vaccines are the most effective tool we have to prevent this disease, no vaccine is 100% effective. If pertussis is circulating in the community, there is a chance that a fully vaccinated person, of any age, can catch this very contagious disease.

Bordetella pertussis and Bordetella parapertussis: two immunologically distinct species. Bordetella pertussis and Bordetella parapertussis are closely related species. Both are responsible for outbreaks of whooping cough in humans and produce similar virulence factors, with the exception of pertussis toxin, specific to B. pertussis.
