Pneumocystis pneumonia
Pneumocystis pneumonia: form of pneumonia caused by the yeast-like fungus Pneumocystis jirovecii, most commonly as an opportunistic infection in the immunosuppressed
Q Fever
Q Fever: infection caused by Coxiella burnetii
Selective Digestive Decontamination
Selective Digestive Decontamination (SDD) is a prophylactic strategy to prevent or minimize nosocomial endogenous and exogenous infections in critically ill patients
Soil-related Infections
Soil-related Infections
Staphylococcus Aureus
Staphylococcus Aureus: aerobic gram positive cocci; has developed beta-lactamase activity thus is not susceptible to penicillin (use flucloxacillin at doses of 2g 4-6 hrly)
Tetanus
Tetanus: potentially lethal condition characterised by muscular rigidity and spasms, caused by the tetanospasmin toxin produced by Clostridium tetani, that may lead to life-threatening respiratory failure and autonomic dysregulation in severe cases
Toxoplasmosis
Toxoplasmosis: disease caused by Toxoplasma gondii; obligatory intracellular protozoan; cat gut multiplication -> oocysts excreted in faeces -> invasion of hosts and formation of tissue cysts (retinal and brain).
Tuberculosis
Tuberculosis (TB) is the most important infectious cause of death worldwide and is caused by the Mycobacterium tuberculosis complex
Urosepsis
Urosepsis is a severe infection, distinguishing it from other urinary tract infections including mild pyelonephritis and accounts for ~5% of severe sepsis; whereas UTIs account for ~40% of nosocomial infections
Varicella Zoster
Varicella Zoster VZV = an alpha herpes virus; 90% of adults have evidence of infection; spread via droplet excreted from the throat of patients with chicken pox OR via contact with vesicle fluid in chicken pox or shingles.
