Bordetella pertussis Bordetella pertussis is a strict human pathogen that is the causative agent of pertussis (whooping cough). Its natural habitat is in the human respiratory mucosa. Whooping Cough, or pertussis, is a respiratory infection in which a “whooping” sound is produced when the sufferer breathes.

- Pertussis is caused by a bacteria that can easily be spread from person to person. Babies can catch pertussis from anyone around them (e.g., parents, siblings, grandparents, or. babysi©ers) who spread the disease while holding or caring for the baby. The bacteria travels through the air on droplets of saliva.

Bordetella a genus of gram-negative coccobacilli, some species of which are pathogens of the respiratory tract of humans, including Bordetella bronchiseptica, B. parapertussis, which causes mild pharyngitis, and B. pertussis, the causative agent of pertussis. See also parapertussis, pertussis.

Pertussis or Whooping Cough Fact Sheet Pertussis is also called whooping cough. It is a serious lung infection caused by bacteria. It is also very contagious and causes coughing fits. Whooping cough is most serious for babies with very small airways. It can lead to death.

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.

Pertussis: A Disease Affecting All Ages Bordetella pertussis, a highly communicable gram-negative coccobacillus, causes pertussis (whooping cough). B. pertussis is an exclusively human pathogen that is transmitted via airborne droplets. The organism produces antigens that can cause local cell damage and may mediate systemic symptoms.

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 infection causes a violent series of coughing fits ending in a high-pitched intake of breath that sounds like a whoop, giving the disease its other name: whooping cough. These coughing fits can be so severe that patients may vomit, lose consciousness, or turn blue from lack of oxygen.

Humus Thus stable humus contributes little to the pool of plant-available nutrients in the soil, but it does play a part in maintaining its physical structure. A very stable form of humus is that formed from the slow oxidation of black carbon, after the incorporation of finely powdered charcoal into the topsoil.

Pertussis Pertussis, also known as whooping cough or 100-day cough, is a highly contagious bacterial disease. Initially, symptoms are usually similar to those of the common cold with a runny nose, fever, and mild cough.This is then followed by weeks of severe coughing fits.he multicomponent acellular pertussis vaccine is 71–85% effective with greater effectiveness for more severe strains. Despite widespread vaccination, however, pertussis has persisted in vaccinated populations and is today one of the most common vaccine-preventable diseases in Western countries.

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.

- Causes. Pertussis, a respiratory illness commonly known as whooping cough, is a very contagious disease caused by a type of bacteria called Bordetella pertussis.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 toxin Pertussis toxin (PT) is a protein-based AB5-type exotoxin produced by the bacterium Bordetella pertussis, which causes whooping cough. PT is involved in the colonization of the respiratory tract and the establishment of infection.he appearance of pertussis is quite recent, compared with other epidemic infectious diseases. The earliest mention of pertussis, or whooping cough, is of an outbreak in Paris in 1414. This was published in Moulton’s The Mirror of Health, in 1640.

Pertussis (whooping cough) Pertussis (Whooping Cough) Pertussis, also known as whooping cough, is a highly contagious respiratory disease. It is caused by the bacterium Bordetella pertussis. Pertussis is known for uncontrollable, violent coughing which often makes it hard to breathe. After fits of many coughs, someone with pertussis often needs to take deep breaths which result in a whooping sound.

- 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.B. parapertussis releases toxins that seem to cause a milder form of pertussis (whooping cough).

- Pertussis [edit]. Pertussis (or whooping cough) is an infection of the respiratory system characterized by a “whooping” sound when the person breathes in. In the US, it killed between 10,000 and 20,000 people per year before a vaccine was available.. 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.
