Cough : (aka: Pertussis)
![Page 4: CHILDHOOD DISEASES. Bacteria Small in size, no nucleus or membranous organelles Cell wall Cocci Bacilli Spirilla Vibrios Gram-positive](https://reader035.fdocuments.us/reader035/viewer/2022062322/56649ea05503460f94ba28c2/html5/thumbnails/4.jpg)
Pertussis
AKA: Whooping cough or 100 day cough
Bordetella pertussis
Was one of the most common childhood diseases and major cause of childhood mortality

Pertussis Starts out like a cold
But cough becomes more severe
Cough characterized by high pitch whoop.
Child may turn cyanotic, cough more at night, or even vomit due to coughing attack.

Sore Throat

Streptococcus
Strep throat Sore throat for more
than 1 week Temperature >100.4 Pus on back of
throat Possible rash
However: Most sore throats
are not caused by bacteria

Antibiotics
Target bacterial cell wall Target cell membrane Inhibit protein synthesis targets in
bacterial machinery Interfere with bacterial metabolism,
DNA, and RNA synthesis

Antibiotic Resistance
“One of the world’s most pressing public health problems.” (CDC, 2012)
What exactly is it?
Factors: Parental pressure Allergies Farming Time / money
![Page 12: CHILDHOOD DISEASES. Bacteria Small in size, no nucleus or membranous organelles Cell wall Cocci Bacilli Spirilla Vibrios Gram-positive](https://reader035.fdocuments.us/reader035/viewer/2022062322/56649ea05503460f94ba28c2/html5/thumbnails/12.jpg)
“Friendly” Bacteria
Most bacteria are non-pathogenic Some bacteria are beneficial
Ex: Bacteria keeps yeast in check. Antibiotics kill bacteria; yeast infection
occurs
Yogurt Probiotics/Prebiotics

Poliomyelitis (Polio)
Polio = gray; Myelon = marrow of spinal cord; itis = inflammation
Highly contagious May result in paralysis
Vaccine preventable

Polio Eradication
Is it possible??
“Hopefully by 2015 no child in the world will be paralyzed by the disease and by 2018 Polio will be wiped out.” – Bill Gates, 09/28/2012
The current eradication program…
