The arrangement represented in the figure is typical of which of the following genera of bacteria?
What bacterial structure is responsible for separating the daughter DNA molecules after replication?
Which of the following characteristics distinguish the archaea from the bacteria?
The archaea known as halophiles
Low G + C content Gram-positive bacteria are
Which of the following diseases is NOT associated with bacteria that form endospores?
Which of the following bacterial genera includes species that protect areas of the body such as the intestinal tract and the vagina from invasion by pathogens?
Which of the following bacterial genera is used for the degradation of environmental pollutants?
Which of the following is NOT associated with bacteria in the genus Streptomyces?
What feature of mycobacteria is responsible for the unusually slow growth of these bacteria?
Members of which of the following genera are the most common sexually transmitted bacteria in the United States?
A microbiologist observes what appears to be a pink-staining long rod within the periplasmic space of a Gram-negative bacillus. What is the structure likely to be?
Which of the following statements regarding pseudomonads is FALSE?
The anaerobic Clostridium species are troublesome pathogens largely because of their capacity for
Gram negative facultative anaerobes that metabolize carbohydrates via glycolysis are members of the
A Gram-positive psychorotrophic rod _____ is a frequent contaminant of milk and meat and an opportunistic pathogen of the immunocompromised.
The process by which a bacterial cell produces an endospore is called (endosporing/ sporulation/ vegetation).
The rod-shaped (rickettsias/ chlamydias/ brucella) are intracellular parasitic members of the alphaproteobacteria.
Some members of the alphaproteobacteria produce a structure called a (prosthecae/ pilus/ filament) to produce extra surface area for nutrient absorption.
The G + C content is an (RNA/ structural/ genetic) determination used in classifying the different taxa of Gram positive bacteria.
The (streptobacilli/ actinomycetes/ mycoplasmas) are a group of Gram-positive bacteria that form branching filaments resembling those of fungi.
The Genus of pathogenic cocci responsible for a wide range of human disease and whose members grow in chains is (Staphylococcus/ Streptococcus/ Enterococcus).
The members of the (alphaproteobacteria/ gammaproteobacteria/ actinomycetes) may alternate between a flagellated motile stage and a nonmotile stage attached by means of a prosthecae.
Slow growing bacteria in the genus (Mycoplasma/ Mycobacterium) are able to withstand long exposure to air because of the presence of mycelic acid in their cell wall structure.
The (bacilli/ Lactobacilli/ bacteroids) are a group of Gram-negative bacteria that include obligate anaerobes normally found in the intestinal tract of animals and humans.
