Microbiology Questions

OLN

An animal that transfers a pathogen from one host to another or from a reservoir to a host without being infected by the pathogen itself

OLN

Lipid molecules with attached sugars that are found as components of gram-negative outer membranes

OLN

A ring structure formed from complement proteins C6 through C9 that penetrates the membranes of a targeted cell, causing cell lysis and death

OLN

The interval of growth when cells divide exponentially; also known as the exponential growth phase

OLN

A known volumes are vacuum filtered aseptically through a membrane with a pore size small enough to trap microorganisms, which are counted after growth on plates

OLN

Name the bean-shaped organs situated throughout the body that contain areas called germinal centers, which are rich in B and T lymphocytes

OLN

Name a toxin that affects cell membrane function by either forming pores or disrupting the phospholipid bilayer

OLN

Name the process in which rapid freezing, followed by placement under a vacuum, of a material so that water is lost by sublimation, thereby inhibiting microbial growth

OLN

An activated and differentiated B cell that is programmed to respond to secondary exposures to a specific antigen

OLN

Name an organelle of the endomembrane system that contains digestive enzymes that break down engulfed material such as foodstuffs, infectious particles, or damaged cellular components

OLN

It is the ability of the specific adaptive immune system to quickly respond to pathogens to which it has previously been exposed

OLN

Name an inflammatory response that involves both the brain and the membranes that surround it

OLN

A type of inclusion containing volutin, a polymerized inorganic phosphate that appears red when stained with methylene blue

OLN

A virus composed of a nucleic acid core, either DNA or RNA, surrounded by a capsid

OLN

The the sequencing of genomic fragments from microbial communities, allowing researchers to study genes from a collection of multiple species

OLN

The science of studying a collection of mRNA molecules produced from microbial communities

OLN

The member of the quinolone family that functions by inhibiting the activity of DNA gyrase, blocking DNA replication

OLN

An antibacterial and antiprotozoan drug of the nitroimidazole class that is activated in anaerobic target cell and introduces DNA strand breakage, thus interfering with DNA replication in target cells

OLN

A part of the upper throat (pharynx) extending from the posterior nasal cavity; carries air inhaled through the nose

OLN

Glycoprotein expressed on the surface of all nucleated cells and involved in the presentation of normal “self” antigens and foreign antigens from intracellular pathogens
