Transcript of Whooping Cough

- catching the disease
Pertussis Toxins
Tracheal Cytotoxin - Stop cilia from beating
Pertussis Toxin - helps development and colonisation
Adenylate cyclase toxin (ACT) - same as above
Inside the body
What happens next?
Whooping Cough, or Pertussis, is a condition caused by a bacterium known as
Bordetella pertussis

It can occur at any age, but effects are worst in infants. It can be vaccinated against.

The bacteria is pathogenic only to humans (Guiso, 2009).

The first stage or the
Catarrhal stage
is the stage where 'normal cold' symptoms happen (eg. runny nose, cough)

The second stage or the
Paroxysmal stage
is what the disease is known for: bursts of coughing appear, known as Paroxysms punctuated by loud breathing in (hence whooping). It can also lead to pneumonia.

Final stage is recovery. Pan to the right for a video of the second stage.
The Role of Vaccinations
Vaccinations have greatly reduced the amount of deaths that occur from infectious diseases worldwide and in Australia.
What is Immunity?
How to be immune?
Immunity is the ability to fight off infections/diseases by a pathogen through the use of antibodies
Immunity and Vaccinations
and Whooping Cough

Whooping Cough is usually spread by coughing or sneezing -- then others breathe it in
Among case-infants, family members were the main source of pertussis. (Bisgard, et al 2004)
The Human Immune Response
"The Issues"
Active Immunity
When an organism's immune system form memory cells in response to a pathogen
1st Line of Defense
Keep the invaders out!
The 1st line of defense has chemical or physical
barriers to prevent entry of pathogens in the first place -- in this case, pertussis
Skin - an excellent barrier
Mucus Membrane and Cilia
2nd Line of Defense
Destroy it before it causes harm!
Macrophages and mainly Neurophils are involved in detecting and eliminating
B. Pertussis
Evidence indicates that neutrophils
appear to be the main target cells
for ACT. (Andreasen and Carbonetti, 2009)

The toxin suppresses innate immune responses during early infection (Connelly, et al. 2012)

3rd Line of Defense
Macrophages which consume the antigen
toxins and bacteria takes a fragment
and presents it on it's
Pertussis Toxin has been shown to target airway macrophages to allow for a delayed response (Carbonetti, et al, 2007)
*ACT is an enzyme for the conversion of ATP to cAMP
The Specific Response
On second infection, there is a faster, rapid and elevated response and antibodies are made quickly.
Passive Immunity
When an organism develops temporary immunity from antibodies given in some other way (i.e. no memory)
Gram stain of B. Pertussis
Complement Proteins
Why should we vaccinate?
Protection from Diseases
Eradication and Elimination
Lower health care costs
Higher life expectancy
Herd Immunity
(Andre F, et al.

Herd Immunity
Herd Immunity is the fact that when a high
proportion of the population is immunised,
the risk of infection by a suceptible individual
is lower.
Why does this work?
Transmission of diseases is slowed down and
immune people acts as a 'barrier' against the

A new whooping cough epidemic
in Australia
Myth: Vaccination causes autism
In a paper submitted by Andrew Wakefield to the Lancet in 1998, he suggested that there was a link between autism and vaccination (more specifically MMR).
This led to a decline in
vaccination rates because of
fears of autism (and the establishment of anti vaccination groups).

The paper has since been
retracted (Lancet, 2010) but the damage is done.

A systematic review found that there was
no link
between vaccinations (MMR) and autism (or any other disease). (Demicheli et al., 2012)
Studies show that the current whooping cough vaccine was less effective than it's predecessor (article published by Nogrady)

Data has shown that the DTaP vaccine is 78% effective in preventing whooping cough on the first instance. (Chiappini et al., 2013)

Is this leading to further outbreaks? What can we do to stop it?

Toxins caused statistically significant
reduction in phagocytosis (Mobberley-Schuuman et al, 2003)
