Microbiology HCC Final Assessment Questions
2025 | Full Verified Guide | A+ Rated
Metronidazole - Drug used for protozoan infections
Helminthic - Mebandazole, niclosamide, and ivermectin are the drugs used to treat this
type of infection
Microlides - A class of natural products that consist of a large macrocyclic lactone ring to
which one or more deoxy sugars, usually cladinose and desosamine, may be attached.
Fluoroquinolones - These drugs work by binding to DNA gyrase and a related enzyme;
topoisomerase IV, both of which are essential for replication of the bacterial DNA
Pathogens - any agent-usually a virus-bacterium, fungus, protozoan, or helminth-that
causes disease
Decomposers - a consumer that feeds on organic matter from the bodies of dead
organisms. These microorganisms feed from all levels of the food pyramid and are responsible
for recycling elements (also called "saprobes")
Genetic Engineering - a field involving deliberate alterations (recombinations) of the
genomes of microbes, plants, and animals through special technological processes.
Biotechnology - the use of microbes or their products in the commercial or industrial
realm.
Characteristics of Viruses - 1) Obligate, intracellular parasites of bacteria, protozoa, algae,
fungi, plants, and animals
2) acellular: not cell-like
3) ultra-microscopic
4) do not have characteristics of life
5) inactive while outside host cell
6) Basic structure consists of protein shell (capsid) which surrounds a nucleic acid (core)
7) Nucleic acid can be either DNA or RNA (never both)
8) Nucleic acid can be ssDNA, dsDNA, ssRNA, dsRNA
, 9) Viruses are specific to host cells (specificity)
10) Multiplies by taking control of host cell's metabolic activities
Phylogeny - the evolutionary development and diversification of a species or group of
organisms, or of a particular feature of an organism
Helminthes - all parasitic worms
Taxonomic Hierarchy - -Domain
-Kingdom
-Phylum
-Class
-Order
-Family
-Genus
-Species
Bioremediation - the introduction of bacteria into the environment as a way to restore
stability
6 I's - -Inoculation
-Incubation
-Isolation
-Inspection
-Information Gathering
-Identification
Inoculation - introduction of a sample into a container of media to produce a culture
Incubation - under conditions that allow growth
Isolation - separating species from one another. A colony consists one of species. An
Isolation technique may involve a Streak plate, pour plate, or spread plate
Inspection - Observing microbes both macro and microscopically
