Question

A patient comes to see you, complaining of a very sore throat. When you examine her, you find that she has a fever of 39-degree Celsius, and you observe that her throat is extremely red, with pus on her tonsils. You swab the pus and make a slide, which you then send to the clinical lab for Gram staining. The lab sends back a report in which it is noted that the slide has many long chains of round cells that have stained purple in color. your patient asks you whether there were also viruses on the slide. you tell her

1) yes but they are of no concern because they are part of her normal microbiota

2) maybe, there were too few to observe among the bacteria

3) maybe, but viruses cannot be observed without an electron microscope

4) unlikely, because viruses seldom cause sore throats in people

5) no, because viruses would be destroyed by the decolorizing step of the gram stain.

Explanation / Answer

Ans)3

I will tell the patient that maybe viruses can also be present in the sputum but viruses cannot be observed without an electron microscope .They are too small.

Also viruses are not visible in Gram staining .They do not take the stain.The bacteria that are visible may be Streptococcus pneumonia .They are purple colour with round shape and in chains.Sometimes viruses also cause sore throat so there is a possibility that viruses might be present as well.
