Diseases - Diagnosis and Epidemiology-
Questions and Answers.
Clinical Microbiology - Answer Diagnosing infectious diseases by identifying pathogenic
microbes and advising medical providers on treatment
- A subset of microbiology
Clinical labs must identify pathogens safely, efficiently and reliably
Safety in the Microbiology Lab - Answer Established to minimize risk of accidental lab
infections
- prevent biological hazards
Biosafety Level (BSL) - Answer Containment potential
BSL1 - BSL4
BSL 1 - Answer - Teaching labs
- do NOT work with known pathogens
- Barrier protection
Barrier protection - Answer gloves, coat, goggles
BSL 2 - Answer - Moderate-risk pathogens
- Barrier protection
- Biological Safety cabinet
BSL 3 - Answer - Emerging and high-risk pathogens
- Barrier protection
- Negatively pressured lab w filters to prevent pathogen escape
- Biological Safety cabinet
BSL 4 - Answer - Emerging and high-risk pathogens spread by aerosols
- Pathogens with no treatment, cure or vaccine
, - Barrier protection

Rules for Microbiology Labs (6) - Answer - Restrict Access
- Practice good personal hygiene
- Use Personal Protective Equipment (PPE)
- Vaccinate
- Handle Specimens Safely
- Decontaminate
Hospital Acquired Infections (HAI) - Answer nosocomial infections
- A local or systemic infection acquired at a healthcare facility
- Can be acquired from patient or hospital personnel
- frequently resistant to antibiotics
Controlling HAI - Answer Start with
- point of patient entry
- assessing potential risks
- applying basic aseptic techniques
Risk Factors for HAI's - Answer - immunocompromised patients
- newborns
- cross-infection
- healthcare personnel
- medical procedures
- surgery
- antibiotic treatment
