Diseases Associated With Respiratory Disease
VIRAL DISEASE
Influenza
Virulence Factor
Mutations is hemagglutinin and neuraminidase that produces new strains via antigenic drift and antigenic shift
Coronavirus Respiratory Syndrome
Virulence Factor
Enter the body via respiratory droplets and adhere to lung cells and destroys cells, triggering
respiratory symptoms, eventually spreading via the bloodstream to the heart and kidneys
#
Signs and Symptoms
Malaise, difficulty in breathing, shortness of breath
#
Common cold
Signs and Symptoms
Sneezing, sore throat, cough, body ache
#
Virulence Factor
Optimum temperature for reproduction – 33°C (nose)
BACTERIAL DISEASE
Tuberculosis
Sign and Symptoms
Minor cough, minor fever Symptoms are generally not apparent
#
Virulence Factor
Cord Factor- Daughter cells strands produced from components of cell wall. Inhibits migration of neutrophils.
Pneumonia
Bacterial Pneumonia (Streptococcal Pneumonia)
Signs and Symptoms
Fever, Chills, Cough, Congestion, Chest pain, Rapid Breathing, Rust-coloured spectrum
Virulence Factor
Caused by
Streptococcus pneumoniae
Adhesins binds to the epithelial cells of the pharynx Capsule that protects them from lysis by phagocytes.
Streptococcal Respiratory Disease
Sign and Symptoms
Pharyngitis, Sore throat, Difficulty in swallowing, Fever, Malaise, Headache, Laryngitis, Bronchitis, Scarlet or Rheumatic fever, Acute glomerulonephritis
Virulence Factors
Caused by Group A Streptococci (
S.pygones
) Depletion of Normal Microbiota followed by the introduction of large inoculum and the impairment of adaptive immunity
MYCOSES
Coccidioidomycosis
Virulence Factor
Caused by
Coccidioides immitis
dimorphic soil fungus in the division Ascomycota
In drought cycles,
C. immitis
grows as a mycelium and produces asexual spores,
which will germinate into mycelia
The fungus assumes a pathogenic yeast form at human body temperature
Blastomycosis
Signs and Symptoms
cutaneous blastomycosis, necrosis
(death of tissues) and cavity formation
Virulence Factor
Inhalation of dust carrying fungal spores infects the lungs
In the lungs, spores germinate to form yeasts and
multiply
Histoplasmosis
Signs and Symptoms
coughing with bloody sputum or skin lesions
