Ch, 10 Classification of Microorganisms

Bergey's Manual of Systematic Bacteriology differs from Bergey's Manual of Determinative Bacteriology in that the former

• groups bacteria into species.

• groups bacteria according to phylogenetic relationships.

• groups bacteria according to pathogenetic properties.

• groups bacteria into 19 species.

• all of the above.

Bacillus and Lactobacillus are not in the same order. This indicates that which one of the following is not sufficient to assign an organism to a taxon?

• biochemical characteristics

• amino acid sequencing

• phage typing

• serology

• morphological characteristics

Which of the following is used to classify organisms into the Kingdom Fungi?

• ability to photosynthesize; possess a cell wall

• unicellular; possess cell wall; prokaryotic

• unicellular; lacking cell wall; eukaryotic

• absorptive; possess cell wall; eukaryotic

Which of the following is false about scientific nomenclature?

• Each name is specific

• Names vary with geographical location.

• The names are standardized

• Each name consists of a genus and specific epithet

You could identify an unknown bacterium by all of the following except:

• Hybridizing a DNA probe from a known bacterium with the unknown's DNA

• making a fatty acid profile of the unknown

• ribosomal RNA sequencing

• percentage of guanine + cytosine.

The wall-less mycoplasmas are considered to be related to gram-positive bacteria. Which of the following would provide the most compelling evidence for this?

• They share common rRNA sequences.

• Some gram-positive bacteria and some mycoplasmas produce catalase.

• Both groups are prokaryotic.

• Both groups contain human pathogens
