Media that can be used for isolating Bacillus anthracis include:
a. Thayer-Martin agar.
b. 5% sheep blood agar.
c. MacConkey agar.
d. Columbia blood agar with colis-tin-nalidixic acid (CNA).
B
All Bacilli and related genera grow well on 5% sheep blood agar, chocolate agar, routine blood culture media, and commonly used nutrient broths. They will not grow on MacConkey agar, and those that are susceptible to nalidixic acid will not grow on Columbia blood agar with CNA. Two special media are used for the isolation and identification of B. anthracis. Polymyx-in-lysozyme-ethylenediaminetetraacetic-thallous (PLET) acetate can be used for the selection and isolation of this species from contaminated specimens. As a means of identification, bicarbonate agar is used to induce B. anthracis capsule formation.

Match each description below with the type of cell junction it characterizes:
a. adherens junction b. desmosome c. hemidesmosome d. tight junction e. gap junction ____________ Transmembrane proteins on the plasma membrane arranged in a ring that bind to a similar protein ring on an adjacent cell to allow transfer of materials between the cells. ____________ A mesh-like attachment between cells formed by binding of transmembrane proteins of one cell to the same protein type on the adjacent cell, preventing substances from passing between cells. ____________ A band-like attachment where cadherins attach to microfilaments inside the cell and to the extracellular domain of an adjacent cell's cadherin proteins on the outside of the cells. ____________ A button-like point of attachment where integrins attach to intermediate filaments inside the cell and to a protein of the extracellular matrix on the outside of the cells. ____________ A button-like point of attachment where cadherins attach to intermediate filaments inside the cell and to the extracellular domain of an adjacent cell's cadherin proteins on the outside of the cells.
