Study Notes

A Comprehensive Guide to Asepsis and Pathogens

Asepsis means being free of microorganisms that can cause infection.
Medical and surgical asepsis are two ways to achieve asepsis in healthcare settings.
Medical asepsis involves reducing the number of pathogens through hand hygiene, cleanliness, and disinfection.
Surgical asepsis involves complete sterilization of objects and surfaces through various methods, including autoclaving and gas sterilization.
Sterile fields are microorganism-free areas prepared for invasive procedures with high infection risk.
Aseptic technique involves using practices and procedures to prevent contamination from pathogens.
The four main aspects of aseptic technique are barriers, patient equipment and preparation, environmental controls, and contact guidelines.
Barriers, such as sterile gloves and gowns, protect the patient from pathogens from healthcare workers or the environment.
Pathogens, including bacteria, viruses, fungi, and prions, can cause diseases and infections.
Bacteria can be classified by shape, staining reaction, and oxygen requirements and can cause diseases such as strep throat and tuberculosis.
The cycle of infection involves six conditions that must be present for an infection to be transmitted, including an infectious organism, reservoir, portal of exit, susceptible host, means of transportation, and portal of entry.
There are six main routes of transmission, including direct and indirect contact, fomites, vectors, vehicles, airborne means, and droplets.Fundamentals of Disease Transmission and Human Body's Defenses
Disease transmission can occur through direct contact, vectors, vehicles, droplets, or airborne particles.
Vectors are living organisms that can transmit pathogens through their bite, such as mosquitoes, fleas, and ticks.
Vehicles are contaminated mediums that can transport pathogens, including food, water, drugs, and blood.
Droplets are large fluid droplets contaminated with pathogens that can spread through coughing, sneezing, or speaking and can get in contact with a susceptible host’s mucous membranes.
Airborne particles are very small dust or particles of evaporated droplets contaminated with pathogens or spores that can easily be inhaled by a susceptible host.
The human body has natural barriers and defenses, including skin, mucous membranes, enzymes, pH, salts content, and beneficial bacteria.
Inflammation causes increased blood flow to the affected tissue area with the formation of fluids containing white blood cells that try to attack and destroy the pathogen.
Interferons are specialized proteins produced by virus-infected cells to protect the surrounding healthy cells.
Acquired immunity is a long-term resistance to a specific infection through previous contact with a microorganism or induced by a vaccine.
B-cells are specialized white blood cells that produce specific proteins called antibodies that destroy the pathogens' proteins.
Passive immunity is a temporary immunity that happens when antibodies to a specific infection are coming from another individual and delivered through injection, breast feeding, or umbilical cord.
Passive immunity is temporary because the receiver’s body doesn’t produce its antibodies.
