Answers Rated A+(2025-2026).
Staphylococcus aureus - Answer Normal microbiota, can become opportunistic, catalase
positive, MRSA.
Uses hyaluronidase, coagulase, enterotoxins (hemolysins, staphylosins, leukocidins).
Associated diseases of S. aureus - Answer Boils, furunicles, folliculitis, impetigo, scalded skin
syndrome, food poisoning, toxic shock syndrome, bacterial conjunctivitis, septic shock.
Bacterial pathogens of the skin: - Answer Staphylococcus aureus, Staphylococcus epidermis,
Propionibacterium spp, Bacillus anthracis.
Bacterial pathogens of the eye - Answer Moraxella catarrhalis, Streptococcus pneumonae,
Haemophilus influenza, Staphylococcus aureus,
Propionibacterium spp - Answer Causative agent of acne.
Norma microbiota that can become opportunistic.
Non-communicable.
Bacillus anthracis diseases - Answer Skin: cutaneous anthrax with black eschar.
Respiratory: respiratory anthrax if endospores are inhaled.
Digestive anthrax if endospores are ingested.
Bacillus anthracis transmission - Answer Direct contact = cutaneous anthrax
Ingestion of endospores = digestive anthrax
Inhalation of endospores = respiratory anthrax
Zoonotic (mostly from cattle) in most cases, can be used in biological warfare.
Key feature of Bacillus anthracis: - Answer Forms endospores. Reapiratory most deadly of
diseases.
,Staphylococcus aureus
Transmission of bacterial conjuctivitis - Answer Direct contact (most pathogens)
Causative agents of neonatal conjuctivitis - Answer Neisseria gonorrhea
Chlamydia trachomatis
How can a baby acquire neonatal conjuctivitis? - Answer Direct contact w/ infected mother
through birth canal
Trachoma - Answer Caused by Chlamydia, leading cause of preventable blindness worldwide.
Causative agent of Otitis externa - Answer Pseudomonas species of bacteria
Otitis externa is often called - Answer Swimmers Ear
Causative agents of Otitis media - Answer Moraxella catarrhalis
Streptococcus pneumonae
Haemophilus influenza
(All opportunistic pathogens)
Otitis media is often associated with: - Answer Bacterial rhinosinusitis
Viral pathogens of the skin - Answer HPV
Herpes simplex 1 & 2
Roseola (Herpes simplex 6 & 7)
Parvovirus (5ths disease)
Coxsackievirus (Hand, Foot, Mouth)
HPV - Answer Causes warts and cancers
Direct contact transmission
, Direct contact transmission
Often asymptomatic transmission
Usually on mucous membrane but can be anywhere
Often treated with acyclovir
Herpes simplex 1 is usually - Answer Primarily oral
Herpes simplex 2 is usually - Answer Primarily genital
Roseola - Answer Mild viral infection in young children
Causes cold-like symptoms followed by a rash
Herpes simplex 6 and 7
Transmission: direct contact with saliva and respiratory droplets
Parvovirus - Answer Fifths Disease
Similar to roseola but with "slapped cheek" rash followed by body rash
Mild in children, more severe in adults
Transmission: direct contact with bodily fluids
Coxsackievirus - Answer Hand, Foot, Mouth disease
Fever, sore throat, rashes with blisters on hands, feet, and mouth
Associated with loss of appetite
Transmission: direct contact with secretions from blisters or mucous membranes.
Causative agents of viral conjuctivitis - Answer Adenoviruses
Rhinoviruses
Coronaviruses
All direct contact with secretions
Difference between bacterial and viral conjuctivitis - Answer Viral: lasts longer with watery
discharge
