Which organism appears clear on MacConkey agar and resembles some colonies of the Enterobacteriaceae family?
 
  a. M. lacunata
  b. M. lincolnii
  c. M. canis
  d. M. nonliquefaciens



A large lateral spine is characteristic of which Schistosoma egg?
 
  a. Schistosoma mansoni
  b. Schistosoma japonicum
  c. S. haematobium
  d. Schistosoma mekongi



Testing for differentiation of M. lacunata from other Moraxella species can best be performed by:
 
  a. the ability to utilize acetate.
  b. the ability to liquefy serum.
  c. glucose utilization tests.
  d. growth on MacConkey agar.



The term used to describe a virus that causes a global outbreak of serious illness of which little natural immunity exists and that has sustained person-to-person transmission is:
 
  a. epidemic.
  b. pandemic.
  c. endemic.
  d. widespread.



Nontreponemal antibodies are those that are:
 
  a. produced against antigens of the organ-isms themselves.
  b. produced by infected patients against components of mammalian cells.
  c. produced by the organism that causes the systemic destruction of the disease.
  d. also called heterophile antibodies.

C
M. canis is a nonlactose fermenter, appears clear on MacConkey agar, and resembles some colo-nies of the Enterobacteriaceae family.

A
The eggs of S. mansoni are 115 to 180 m long by 40 to 75 m wide, and they have a large lat-eral spine.

B
M. lacunata is able to liquefy serum; therefore depressions are formed on the surface of Leffler serum agar slants.

B
A pandemic is defined as a virulent human influenza virus that causes a global outbreak of se-rious illness of which little natural immunity exists and that has sustained person-to-person transmission. Often pandemics result in high rates of human mortality with significant social, infrastructure, and economic consequences.

B
Classic serologic tests for treponematosis measure the presence of two types of antibodies: tre-ponemal and nontreponemal. Nontreponemal antibodies, often called heterophile antibodies, are produced by infected patients against components of mammalian cells, whereas treponemal an-tibodies are produced against antigens of the organisms themselves.

I just wanted to write to say thanks a bunch for the answer!
