	MICROBIOLOGY
		What you need to know:   Most cultures need to incubate at least 24 hours.   Gram Stain can be known within hours of submission to lab.   Call microbiology lab if you really want to know the preliminary results. On Note: Gram Stain, Culture Sensitivities of (blood , urine, sputum, stool, csf, wound, incision, catheter) positive/negative Presentation: Example: " Most recent blood culture 2/4 positive for gram - rods, likely E.coli. Sensitive to ciprofloxacin. Culture from sputum shows gram - rods, likely E. Coli." Keep these trends in mind: "Sepsis is overwhelming systemic disease resulting from infection with a microbial pathogen. Septic shock describes the syndrome of severe sepsis associatated with hypotension. (Critical Care Secrets. 2nd Edition)." Sepsis occurs often in the ICU. Infection in any locale: Urinary Tract, Lungs, Abdomen, Skin can go systemically to cause sepsis.
		Common Bugs: Community Acquired Infections/Sepsis Urinary Tract:   E.coli   Klebsiella Lungs: (Bronchitis, Pneumonia)   Streptococcus pneumonia   Hemophilus Influenza   Legionella   Pseudomonas. Skin: (Cellulitis)   Staph Aureus   Strep Pyogenes Abdominal: (Phlegmon, Abscess)   Anaerobes   Mixed enterics GNR. Nosocomial Infections/Sepsis Urinary Tract:   E.Coli   Klebsiella   Enterobacter   Serratia   Pseudomonas Lung: (Bronchitis, Pneumonia)   Strep pneumonia   Hemophilus Influenza   Legionella   Pseudomonas   Staph Aureus Skin:   Candida   Staph Epidermidis
		Sensitivities: The pharmacy provides these cards as guidelines of understanding a bacteria being sensitive, intermediately sensitive and resistant to an antibiotic.
