Foodborne Illness – Staphylococcus • What is the infectious agent (pathogen) that causes this infectious disease? Staphylococcus is an unmodifiable bacterium that causes Botulism. Which mean that individuals have no control over catching or not catching this disease. Since botulism is such strong and dangerous bacteria‚ that ingesting the smallest amount can make individuals sick. More important is other living forms or life like bacteria’s are changing‚ and becoming resistant to the

(2 pts) Why are patients with cystic fibrosis prone to infections with Pseudomonas aeruginosa? Pseudomonas aeruginosa is an opportunistic infection that usually does not affect healthy patients‚ but is particularly detrimental in patients with cystic fibrosis. This is because they are antibiotic resistant to a certain extent. Paired with this‚ patients with cystic fibrosis have a decreased ability to produce mucous membranes‚ making it easier for biofilms associated with P. aeruginosa (Lyczak et

Pathogens refer to bacterial organisms found in the intestinal tracts of mammals. Nutrient sources include municipal wastewater treatment plants‚ septic systems‚ and agricultural runoffs.

Mycobacterium tuberculosis‚ the causative agent of tuberculosis is a pathogen that can infect its host for decades without causing clinical disease‚ only to reactivate when host immunity is compromised. Recent work has begun to outline the complexity of this host-pathogen interaction and to reveal how the homeostatic balance between the two is achieved.

This allows pathogens to travel easily from the nasal passages and pharynx to the sinuses resulting in a spread of infection (book). B. What is the cough reflex?
