Pneumocystis pneumonia: form of pneumonia caused by the yeast-like fungus Pneumocystis jirovecii, most commonly as an opportunistic infection in the immunosuppressed
A pressure ulcer is localized injury to the skin and/or underlying tissue usually over a bony prominence, as a result of pressure, or pressure in combination with shear
Q Fever: infection caused by Coxiella burnetii
Selective Digestive Decontamination (SDD) is a prophylactic strategy to prevent or minimize nosocomial endogenous and exogenous infections in critically ill patients
Soil-related Infections
Staphylococcal Toxic Shock Syndrome: staphylococcal toxin producing infection -> intoxication of exotoxins (TSS-1, 2 or 3 enterotoxin)-> toxic shock syndrome
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: 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: 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).
Transmission-based precautions are recommended where standard precautions alone may be insufficient to prevent transmission of an infection, such as an outbreak.
