Introduction to microbiology in ICU
Session Overview
Description
This session describes the different classes of organisms that can cause infection, and highlights some of the common pathogens seen on the ICU.

Learning Objectives
By the end of this session you will be able to:

• List different classes of micro-organisms
• Describe Gram staining
• List common pathogen-causing disease on the ICU
• Understand the basic antibiotic treatment of infections in the ICU

Infection is a common reason for hospital admission, and can be complicated by septic shock requiring ICU care. Knowledge of common causative organisms and tailored antibiotic therapy is imperative. This session covers:

Gram stain
Common causes of infections:

• Community-acquired pneumonia (CAP)
• Urinary tract infection (UTI)
• Meningitis
• Intra-abdominal sepsis
• Endocarditis
• Nectorising fasciitis (Nec-Fasc)
• Bone
• Neutropenic sepsis

Classes of bacteria

Fungi:

• Risk factors
• Types
• Diagnosis
• Further investigations

Common viruses:

• Herpes zoster virus (HSV)
• Varicella zoster virus (VZV)
• Cytomegalovirus (CMV)
• HIV

Pneumocystis jirovecii pneumona (PJP)
