Bordetella pertussis and B. bronchiseptica are Gram-negative bacterial respiratory pathogens. Bordetella pertussis is the causative agent of whooping cough and is considered a human-adapted variant of B. bronchiseptica. Bordetella pertussis and B. bronchiseptica share mechanisms of pathogenesis and are genetically closely related 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 cough fits, someone with pertussis often needs to take deep breaths, which result in a whooping sound Transmission of pertussis can occur through direct face-to-face contact, through sharing of a confined space, or through contact with oral, nasal, or respiratory secretions from an infected source Background: The recent increase in whooping cough incidence (primarily caused by Bordetella pertussis) presents a challenge to both public health practitioners and scientists trying to understand the mechanisms behind its resurgence. Three main hypotheses have been proposed to explain the resurgence: 1) waning of protective immunity from vaccination or natural infection over time, 2) evolution.

Mode of transmission of Bordetella pertussis B. pertussis is highly infectious. It may be spread from person to person by close contact, usually by respiratory aerosols, infecting 70-100 per cent of susceptible household contacts Pertussis is a contagious, acute respiratory illness caused by the bacterial pathogen Bordetella pertussis.Although it is widely believed that transmission of B. pertussis occurs via aerosolized respiratory droplets, no controlled study has ever documented airborne transmission of pertussis. We set out to determine if airborne transmission occurs between infected and naive animals, utilizing. Bordetella pertussis is coccobacilli of the phylum proteobacteria that is gram negative and is an obligate aerobe.B.pertussis is also encapsulated and does not produce spores. Being an aerobe is advantageous being that it lives within the human respitory system. B.pertussis was identified as early as 1578 by Guillaume de Baillou, but earlier reports date back at least to the 12th century

[Sarah Gregory] Are these new strains any more transmissible or dangerous than other forms o Pertussis Emerging and Acute Infectious Disease Guidelines-May 2021 310 Pertussis rev March 2021 BASIC EPIDEMIOLOGY Infectious Agent Bordetella pertussis (B. pertussis), a fastidious Gram-negative bacillus Transmission Transmitted from person to person through direct contact with respiratory secretions, mos Disease may occur in those who have been vaccinated, but symptoms are typically milder. Pertussis is caused by the bacterium Bordetella pertussis. It is spread easily through the coughs and sneezes of an infected person. People are infectious from the start of symptoms until about three weeks into the coughing fits Pertussis has reemerged as an important public health concern since current acellular pertussis vaccines (aP) replaced older whole-cell vaccines (wP). In this study, we show nonhuman primates vaccinated with aP were protected from severe symptoms but not infection and readily transmitted Bordetella pertussis to contacts. Vaccination with wP and previous infection induced a more rapid clearance. Bordetella pertussis is a bacterium that can live in the human respiratory tract. The bacteria is easily spread through sneezes and coughs , often from people who often don't even know they have.

Pertussis is caused by the gram-negative coccobacillus B. pertussis, a strict human pathogen with no known animal or environmental reservoir [ 2 ]. The organism is fastidious, surviving only a few hours in respiratory secretions and thus requiring special media for culture Pertussis, more commonly known as whooping cough, is caused by a bacterium (germ), Bordetella pertussis, that lives in the mouth, nose and throat. The germ is highly contagious and is easily spread from person-to-person 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 that 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 Bordetella pertussis is a fastidious gram-negative coccobacillus responsible for the respiratory infection commonly known as whooping cough.
