MCB LAB

Causative, often used in medical settings

Study of disease occurance, etc

Group of orgs which are non- spore-forming Gram-negatiave rods that ferment lactose to acid and gas, such as E. coli

Three tests that make up the bacterial Standard Analysis of Water

Test that is based on gas formation as a result of fermentation in lactose broths; count gas bubbles

Test which confirms actual presence of coliforms, since synergism b/w non-coliform bacteria could also result in gas formation

Once, a Gram-neg lactose fermenter has been isolated, test done to prove that the org truly is a Gram-neg rod, by means of a Gram stain, and does produce gas from lactose in a lactose broth w/a Durham tube

Series of tests done to distinguish E. coli from E. aerogenes

Production of acids and/or alcohol from carbs

Clear area among cloudy bacterial growth where virus has infected and lysed a cell, spreads and infects and lyses other cells

Sequence of infection by a virus

Phages that are able to undergo lysogeny

Type of cycle in which virus stays w/in host DNA for some period of time, being replicated w/host's, and later being released

Cycle of virus that is not delayed

Method of asexual repro by yeasts

An organism, often an invertebrate arthropod, that transmits a pathogen from reservoir to host

Study of natural relationships of organisms

2 diff orgs living in close association

Interaction b/w 2 orgs which benefits both

2 orgs creating a product together that neither is able to create alone

1 org is benefited, other is harmed

Bulges of tissue formed on the plant root when bacteria enter plant, chg shape & fix N2 gas into nitrogenous compounds plant can use

Variable appearance; ability to change cell size and shape

Irregularly-shaped cells formed when bacteria nodules form on roots, which is only form that they can fix nitrogen

Pink compound whose function is to bind oxygen, which keeps the microenv of the nodule anaerobic to allow the nitrogenase enzymes to fix the nitrogen

Area around plant roots

Species that require more than ordinary nutrients

Tube to diagnose UTIs

Protein produced by body's immune system in response to the presence of a foreign substance or org

Foreign substance or org which body reacts to

Visible clumping formed by antibody molecules binding w/bacterial cells or blodo cells, and cross-linking

Agglutination factor which is associated w/blood types

Immunological reaction which involves antigens and antibodies that are in solution, forming a granular product

Tool used for precipitin rxn in which antibody placed in center well & diff antigens are added to each outer well, causing the solutions to diffuse out from their wells through the agar & meeting to form a precipitin
