White means in Hazardous Chemical Classification is:

The study of organisms and agents too small to be seen clearly by an unaided eye

Studied syphilis and he believed it was transferred by “seminaria morbi” or bad seed.

Observed these “animalcules” from rain water samples, his own feces and scrapings from his teeth

Stated that yeast cells are responsible for the conversion of sugar to alcohol.

Demonstrated that routine hand washing can prevent the spread of disease

Paul Ehrlich’s develops chemotherapeutic agent ______ to combat syphilis

First Antibiotic against TB.

Is the academic discipline of defining groups of organisms on the basis of shared common characteristics and giving names to those groups.

Responsible for antibiotic resistance

Highly refractile resting cells that are highly durable and dehydrated with thick walls

A phospholipid bilayer with embedded proteins that envelop the cytoplasm

Water-filled structures that control the passage of nutrients and solutes

A single polar flagellum

Join bacterial cell in preparation of DNA transfer from one cell to another

For adherence of cells to one another and to environmental surfaces.

Bundles of fibrils anchored at one end of spirochete and spiral around the cell.

Cells arranged on chains

Stain bacteria that have high lipid and wax content in their cell walls

Can survive in the presence of oxygen but do not use oxygen for metabolism

Can grow either with or without oxygen

Little or no cell division

cells are at their most active state

End product 2 molecules of pyruvic acid

Converts glucose-6-phosphate to pyruvate and glyceraldehyde phosphate

Allowing complete oxidation of pyruvate

Generate energy in the form of ATP

Mobile elements that contain additional genes

Encodes products that are determinants of antimicrobial resistance

Organism benefits but there is no beneficial or harmful effects to the host.

Microorganisms that colonize an area for months or years.

Organisms recognize to cause disease in healthy immune-compenent inidividuals.

Is the relative ability of a microorganism to cause disease or the degree of pathogenecity

Secreted by the organism into the extracellular environment

Migration of PMNs into area of infection

Movement of PMNs from blood vessel into tissues

Blood-based plates should not show signs of hemolysis, and any other plate that deviates from the normal color should not be used.

Plates should be free of contaminants.

Used for testing streptococci and other fastidious organisms.

Thickness of the susceptibilty agar plate: (5-10 mm)

Prolonged incubation may result in false resistance interpretation

The number of disk per plate:

Effective against a limited number of pathogens

Produced by bacteria or fungi

Is the lowest concentration of drug that kills bacterial growth

Chloramphenicol may lead to live and kidney damage and yellowing the teeth of children

Unable to reach its site of action

Cannot bind to bacterial cell

Blood and all body fluids, including secretions and excretions except sweat, regardless of whether visible blood is present, are considered infectious.

Contact precautions, droplet precautions, and airborne precautions

Are used to stop the spread of infectious agents that may be transmitted through direct or indirect contact with the patient or with the patient’s environment.

These precautions are used for infectious agents, such as Mycobacterium tuberculosis, varicella virus, and rubeola virus, that can remain airborne and infectious over long distances.

A specific term referring to the property by which a biocide is able to inhibit bacterial multiplication

Check the answers that must be seen in a Specimen Label

Accomplished by dry heat, autoclaving, gas, various chemicals (formaldehyde), and radiation.

Removal of microbes from a limited area
