You obtained the following BLAST data from your sample 999 E

You obtained the following BLAST data from your sample: 99.9% Enterobacter sakazakii 95.2% Enterobacter aerogenes 93.7% Enterobacter cloacae The pathogen in your sample is:

A. Enterobacter sakazakii

B. Enterobacter aerogenes

C. Enterobacter cloacae

D. Enterobacter species

Solution

Option A. Enterobacter sakazakii.

BLAST results tells that how much the sequence of the unknown organism matched with already known and sequenced organisms. If the sequence data matched 99.9%with some organism sequence data means you can easily identified unknown organism. Here in this case 99.9%matched with Enterobacter sakazakii means the pathogen sequenced was Enterobacter sakazakii.
