What causes a paroxysmal cough?
Paroxysmal coughing is commonly caused by Bordetella pertussis bacterium. This bacterium infects your respiratory tract (your nose, throat, windpipe, and lungs) and causes whooping cough. This infection is extremely contagious. Paroxysmal coughing is the second stage of whooping cough.
What is the paroxysmal stage of whooping cough?
The paroxysmal stage of Pertussis is characterized by episodes of coughing with a distinctive “whooping” sound when breathing in (inspiration). This characteristic cough gives the disease its common name, Whooping Cough. During the convalescent stage, episodes of coughing are less frequent and symptoms improve.
What bacteria causes whooping cough?
Pertussis, a respiratory illness commonly known as whooping cough, is a very contagious disease caused by a type of bacteria called Bordetella pertussis.
What are the characteristics of Bordetella pertussis?
CHARACTERISTICS: Bordetella pertussis are small, gram-negative, encapsulated, non-motile, coccobacilli with outer pili. They are generally about 0.5-1.0 µm in size 3- 5. Some have reported that the bacteria are covered with surface slime or biofilm composed of carbohydrates 6 .
What is the meaning of wet cough?
A productive (‘wet’ or chesty) cough is when you have a cough that produces mucus or phlegm (sputum). You may feel congested and have a ‘rattly’ or ‘tight’ chest. Symptoms are often worse when waking up from sleep and when talking. The wet cough may be the last symptom left after a common cold infection.
What causes nocturnal cough?
Following are the differential diagnoses of nocturnal cough. In adults with a cough longer than eight weeks, most of the cases are due to post-nasal drip, asthma, eosinophilic bronchitis, and GERD. The causes of chronic cough are the same in children with the addition of bacterial bronchitis.
Can whooping cough recur?
Can you get pertussis more than once? Reinfection appears to be uncommon but does occur. With natural infection, immunity to pertussis will likely wane as soon as seven years following disease; reinfec- tion may present as a persistent cough, rather than typical pertussis.
Which of the following is descriptive of 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.
How does Bordetella spread?
Transmission. Italicize Bordetella spreads through direct contact (licking, nuzzling), through the air (coughing or sneezing), or via contaminated fomites. Transmission can occur between dogs and cats.
Which of the following pathogens causes whooping cough?
Pertussis, also known as whooping cough, is a highly contagious respiratory disease. It is caused by the bacterium Bordetella pertussis.
What is the pathophysiology of whooping cough?
Whooping cough is caused by a type of bacteria called Bordetella pertussis. When an infected person coughs or sneezes, tiny germ-laden droplets are sprayed into the air and breathed into the lungs of anyone who happens to be nearby.
What are the four methods used to identify Bordetella pertussis?
Common laboratory diagnostic methods used for pertussis diagnosis include culture, direct-fluorescent-antibody testing (DFA), serology and polymerase chain reaction (PCR). Culture of Bordetella pertussis is highly specific but fastidious and has limited sensitivity.
