PERTUSSIS 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.

Signs and Symptoms After 1 to 2 weeks and as the disease progresses, the traditional symptoms of pertussis may appear and include: 1  Paroxysms (fits) of many, rapid coughs followed by a high-pitched “whoop” sound. 2  Vomiting (throwing up) during or after coughing fits. 3  Exhaustion (very tired) after coughing fits.

Lyme Disease The vector is once again an arthropod although this time it is a tick rather than a mosquito. The arthropod-borne pathogen for Lyme disease is a now bacterium, rather than a virus, as was the case for both of the two previous arthropod-borne infections we covered.

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 cough fits, someone with pertussis often needs to take deep breaths, which result in a “whooping” sound. Pertussis can affect people of all ages, but can be very serious, even deadly, for babies less than a year old. The best way to protect against pertussis is by getting vaccinated.

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.

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 pertussis (Whooping Cough) and other species M icrobiology. Bordetella pertussis, a small gram-negative coccobacillus, is the most important cause of pertussis. B. parapertussis causes similar, but often milder type of cough with posttussive vomiting. B. bronchiseptica and B. avium are important pathogens in wild and domestic animals.ne explanation for the increase might be the adaptation of B. pertussis bacteria to vaccine-induced immunity, because the antigenic divergence has been recently found between the B. pertussis vaccine strains and circulating strains (13, 60, 61).

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 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. Among vaccine-preventable diseases, Pertussis is one of the most commonly occurring ones in the United States and it remains a cause of high morbidity and mortality among children worldwide.

- Pertussis is known to occur in three to five year cycles. The last peak year in Texas was 2013 with 3,985 cases, the highest annual case count since 1959. There were 1,504 cases in 2015, marking the beginning of the valley of the three to five year cycle.

Immunizations The best way to prevent yourself and your family from pertussis is to get the pertussis vaccine. Two vaccines are available to protect against pertussis. The childhood vaccine is called DTaP (diphtheria, tetanus, and pertussis) and is given to children at 2 months, 4 months, 6 months, 12-15 months of age, and a booster between 4 and 6 years of age.

Pertussis is a very contagious disease only found in humans. It is spread from person to person. People with pertussis usually spread the disease to another person by coughing or sneezing or when spending a lot of time near one another where you share breathing space.

Best Practices for Healthcare Professionals on the Use of Polymerase Chain Reaction (PCR) for Diagnosing Pertussis Optimal Timing for PCR Testing for Pertussis. PCR has optimal sensitivity during the first 3 weeks of cough when bacterial DNA is still present in the nasopharynx. After the fourth week of cough, the amount of bacterial DNA rapidly diminishes, which increases the risk of obtaining falsely-negative results.
