- 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.

Pertussis About the organism. Pertussis (whooping cough) is a highly contagious bacterial disease caused by Bordetella pertussis (a small, aerobic, Gram-negative pleomorphic bacillus). Transmission occurs via respiratory secretions on the hands or in aerosolized form.

- Introduction. Bordetella pertussis was first isolated in pure culture in 1906 by Bordet and Gengou. Today, B pertussis belongs to the genus Bordetella in the family Alcaligenaceae, which contains several species of closely related bacteria with similar morphology. pertussis and B parapertussis cause whooping cough (pertussis) in humans. Other members of the genus are B bronchiseptica, which causes respiratory disease in various animals and is only occasionally found in humans.

Pertussis Pertussis, also known as whooping cough, is an acute infection of the respiratory tract caused by Bordetella pertussis bacteria. Only humans can be affected by this disease. Transmission occurs through direct contact with respiratory droplets spread during coughs and sneezes from an infected person. Symptoms begin with a mild respiratory illness then progresses to prolonged cough episodes with the characteristic whoop or which end in vomiting.

Bordetella Bordetella is a genus of small (0.2 - 0.7 µm), 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.Three species are human pathogens (B. pertussis, B. parapertussis, B. bronchiseptica); one of these (B. bronchiseptica) is also motile.. bronchiseptica causes several diseases in other mammals, including kennel cough and atrophic rhinitis in dogs and pigs, respectively. Other members of the genus cause similar diseases in other mammals, and in birds (B. hinzii, B. avium). The Bordetella genus is named after Jules Bordet.

- Introduction. Whooping cough (pertussis) is a highly contagious bacterial infection of the lungs and airways. The condition usually begins with a persistent dry and irritating cough that progresses to intense bouts of coughing.hooping cough is caused by a bacterium called Bordetella pertussis, which infects the lining of the airways, mainly the windpipe (trachea) and the two airways that branch off from it to the lungs (the bronchi).

Bordetella pertussis Description and significance. 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. It cannot survive in the environment; it must reside in a host either in small groups or singly.

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.

Bordetella pertussis and Bordetella parapertussis: two immunologically distinct species. As expected, pertussis toxin did not protect against B. parapertussis infection, since this bacterium did not express this protein, but the surprising result was that none of the other factors were protective against B. parapertussis infection.

- Pertussis, or whooping cough, is a highly contagious disease involving the respiratory tract. It is caused by a bacterium, Bordetella pertussis, which is found in the mouth, nose and throat of an infected person.ertussis can occur at any age. Severe illness is more common in young children that have not been immunized. Adults with pertussis have milder symptoms. A diagnosis of pertussis should be considered for adults with persistent cough, to ensure they do not pass on the infection.

Bordetella Pertussis Bordetella Pertussis. Bordetella pertussis is a kind of bacteria. It is a gram-negative organism and has a morphology named coccobacillus. It is an aerobic organism, meaning that it has to be in an oxygenated atmosphere in order to survive.he disease has to live in a warmer temperature, like that of the human body. Pertussis is an infection of the respiratory system. It was called the whooping cough since victims of the disease make a whooping sound when breathing.

Pertussis (Whooping Cough) Pertussis is a respiratory disease found only in humans that is caused by the bacterium Bordetella pertussis. The first account of the infection was recorded in the sixteenth century, but it was not until the early twentieth century that B. pertussis was identified as the cause.he DTaP vaccine (made with acellular pertussis, which contains only parts of the pertussis bacterium and does not cause as many side effects as the vaccine made with the whole bacterium) is given in multiple doses, starting at 2 months of age.
