Document Summary
Many microorganisms live in various areas of the body (no harm), supposed to be there. There is a balance in these communities. If balance is disrupted, microorganisms can cause disease. Vagina: yeast (infection: kendeda), lacto basili (attach to epithelial- prevent inflammation) Carrier: source of infection, no symptoms, capable of transmission. Spore: stay latent until can take advantage. Universal precautions: all blood, body fluids, and wastes are considered infected in any client regardless of condition. Bacteremia: presence of bacteria in the blood. Septicemia: overwhelming systemic infection (organs, blood-life threatening). Pathogens are circulating and reproducing in the blood. Broad spectrum: kills both gram neg and pos. Narrow spectrum: kills either neg or pos. Decrease reproduction inside host cell, and does not kill virus. Interfere with mitosis or may increase membrane permeability. Superbugs: microbes which cause serious disease, unresponsive to drugs. Vaccines or drugs are unlikely to be effective against new form. Before they leave mouth- reduce transmission with mask.
