PORTAGE LEARNING BIOD 171 LAB 9 EXAM
Using the observations made and recorded from PL09 Unknown
Pathogen, complete theresults sections accordingly.
1. Given Culture A and Culture B were accidentally mixed, what
observations were made from theGram stain (shown below)?
Gram-positive cocci (spherical) clusters and Gram-negative bacillus
(rods) were observed.
2. Given the results from a MacConkey agar plate shown below, what
is the shape of Culture A?Culture B?
MacConkey agar is selective for Gram-negative bacteria. Thus,
, Culture A must be Gram-positive as no growth was observed. Coupled
to the results of the gram stain, Culture A(Gram-positive) must be the
cocci.
