Chapter 17, Problem 1MCQ
Summary Introduction
Introduction:
Bacteria are prokaryotic organisms. There are four basic shapes of bacteria; rod-shaped, spherical, comma-shaped, and spiral. Bacteria are cosmopolitan in nature. There are some bacteria, which are pathogenic in nature. These bacteria cause diseases in plants and animals. Tuberculosis, cholera, pneumonia, and gonorrhea are some of the diseases that are caused by pathogenic bacteria.

When determining the clinical significance of cultures, a. the number of microbes is signifi cant. b. the presence of a single colony of a true pathogen may indicate the presence of the disease if the culture comes from a site known to be sterile (i.e., cerebrospinal fl uid). c. the repeated isolation of a relatively pure culture of any microorganism can mean it is an agent of disease, although this is not always the case. d. a range of tests may be needed to identify a pathogen. e. all of the above are true.
A microbiology student was given a mixed culture of two different gram positive bacteria species to grow into a culture medium using correct aseptic techniques. After two days,one gram positive bacterial species grew on the media and the growth appeared red on the surface of the medium. Tthe second gram positive bacterial species grew and the growth appeared yellow on the surface of the medium. What is the possible explanation for the differences in the color of the bacterial growth?
A.
the culture was contaminated
B.
the microbiologist put too much inoculum on the culture medium
C.
the medium was a selective medium
D.
the medium was differential
An elderly man with influenza acquires a case of pneumonia. Gram-positive cocci isolated from his
sputum give beta-hemolysis on blood agar. The infection is very difficult to treat. Later, it is shown
that the man shared the room with a patient with bone infection. Isolates from both infections were
the same.
a. Describe 2 biochemical tests that can be used for the definitive diagnosis.
b. Describe 2 virulence factors of this pathogen and implicate them in diseases.
