Gram reaction, shape and location-specific bacteria, but not diagnostic, as well as different types of the same family may look the same. Epidermal staphylococcus always gram-positive cocci in bunches, and then Staphylococcus aureus and Escherichia coli Gram-negative rods always, but like all other members of one family. If we were investigating food sample from a suspected food poisoning by finding Gram-negative rod in strattera online food would be useful, because it probably means that the infection is associated with
E. coli or similar body, but not Staphylococcus aureus. Of course, further testing of gram-negative rod will need to uniquely identify it. .
