Shah Chapter 1 Flashcards
Viruses
Obligate intracellular parasites; particles either DNA or RNA (not cells); cause diseases like flu, chicken-pox, common cold, and rabies
Microbiology
Study of small living things usually not observed w/o microscope individually
Microorganism
too small to be seen w/o magnification
microscopic
invisible to the naked eye
macroscopic
visible to the naked eye
Pathogen
any microorganism that causes disease
opportunistic pathogen
situation where nonpathogenic or weakly pathogenic microbes cause disease in a immunologically compromised host
colony
a macroscopic cluster of cells in a solid medium arising from the multiplication of a single cell
no nucleus
bacteria & viruses, viruses cannot reproduce unless in a cell
True nucleus
Protozoa, Algae, Fungi & Helminths
Protozoa
Ingests
Algae
Photosynthesis
Fungi
absorbs
Helminths
only animal causing disease
tapeworms
absorbs nutrients
roundworms
Eat intestines
Bacteria
single cell, prokaryotic, causative agent of Lyme disease
vector
transmits infectious agents from one host to another, usually biting, piercing such as tick, mosquito or fly
parasite
the organism that lives on or within the host which it obtains its nutrients and enjoys protection
Vector of Lyme Disease is a member of which group in microbiology
Animal
Secretes enzymes out of there body and into whatever host they are using, those enzymes breakdown the tissue of the host and then the organism absorbs the breakdown products, some examples of this group are single celled & multicellular
Fungi
Prokaryotic Cells
no nucleus or organelles
Eukaryotic Cells
True nucleus & mitochondria
Study of fungi
Mycology
Classification, naming, & identification of microorganisms
Taxonomy
Cleaning up environmental pollution using life forms
Bioremediation
