Exam 3: Bacteria and Archaea

An RN in a primary care office is caring for a 15-year-old male with severe gastrointestinal distress. The patient reports four days of diarrhea, vomiting, and intermittent fever. A stool culture was ordered in an attempt to identify a disease-causing pathogen. -The laboratory report concludes that the diagnosis is salmonellosis caused by Salmonella infection. Remembering resources available for prokaryotic identification,the RN speculates that the laboratory technicians may have used 

Gram-negative bacteria

The function of bacterial endospores is ________.

An RN in a primary care office is caring for a 15-year-old male with severe gastrointestinal distress. The patient reports four days of diarrhea, vomiting, and intermittent fever. A stool culture was ordered in an attempt to identify a disease-causing pathogen. -The patient is diagnosed with Salmonella enterica serovar Enteritidis infection,a foodborne illness. The identification of the bacterial subspecies is important for developing his treatment plan and was possible due to ________.

During the Gram stain,________ cells decolorize when the alcohol is applied.

If you looked at a ________ under the microscope,you would likely see an irregular cluster of spherical cells.

The typical definition of a species is one with distinct characteristics that produce viable offspring when mated with another organism in the same species.  Bacterial species cannot be defined as readily,due to the fact that
