Bordetella pertussis is a Gram negative coccobacillary bacteria that causes the disease called whooping cough, whooping cough or whooping cough.

It was described for the first time by Bordet and Gengou in It is characterized by being a highly contagious pathology of the respiratory tract in all stages of the disease. There is no passive immunity from mother to newborn, so babies are susceptible from birth. Fortunately, this disease is preventable with a vaccine and, as a result, the prevalence is low in developed countries. However, in underdeveloped countries it is the main vaccine-preventable Bordetdlla that causes more morbidity and mortality. Whooping cough is most common in children under 7 years of age, but deaths can occur in any unvaccinated or incompletely vaccinated age group.

It is not known as an animal reservoir Pertussos it survives with difficulty in the environment. It is an immobile bacteria and very demanding from a nutritional point of view. It acts as a promoter of lymphocytosis, a pertussis, an activating factor of the islets of the pancreas and a sensitizing factor to histamine. Triggers hypoglycemia.

It is an immunogenic protein of the outer membrane that helps filamentous hemagglutinin to mediate the attachment of microorganisms to cells. It has a necrotizing activity, it destroys the epithelial cells of the respiratory tract producing a decrease in ciliary movement. It is believed to be responsible for the characteristic paroxysmal cough.

It also affects the function of polymorphonuclear cells. It is endotoxic due to the content of lipid A, which is responsible for general manifestations such as fever during illness. It is a thermostable somatic antigen that is present in all species of the genus, including thermolabile ones that help adherence. It produces local sensitization to histamine and reduces T lymphocytes. With this, the bacteria evade the immune response and prevent phagocytosis. Bordetella pertussis It appears as a small Gram-negative coccobacillus mainly in primary cultures, but in subcultures it becomes pleomorphic.]
