Study Notes
Microbiology and Infection Control
- Culture and sensitivity tests determine the growth and antibiotic sensitivity of microorganisms
- Different types of microorganisms have distinct morphologies, such as streptococci in chains and spirochetes in a corkscrew shape
- Infection is the invasion and multiplication of pathogens in the body
- Helminthology is the study of parasitic worms
- Common portals of entry/exit for infections include respiratory and GI mucosa, blood, and sputum
- Ringworm is caused by a fungus
- Opportunistic infections occur when normal flora is disrupted or the host's immune system is weakened
- Hepatitis A is transmitted via the oro-fecal route
- Normal flora in the body provides benefits such as occupying space and producing vitamin K
- Fomite refers to inanimate objects, while vectors are animals that transmit diseases
- The body has three lines of defense against disease: prevention of entry, nonspecific defenses, and specific defenses
- Pasteurization reduces microorganisms, while sterilization kills all microorganisms and spores. Disinfectants, antiseptics, and antibiotics have specific roles in controlling infections.
