Inclusion bodies:are the site of virusReplication.

All the DNA virus replicate in the nucleus

All the RNA virus replicate in the cytoplasm

First

Intranuclear inclusion bodies

Because the virus replicates in the nucleus , you will see that the nucleus is dark in stain andlarge because of the hyperchromatism , the mitosisand the multiplication occurring in the nucleus and remember that they are for the DNA viruses

Second

Intracytoplasmic inclusion bodies

It has got the same idea as the Intranuclear Inclusion bodies but they are in the cytoplasmAnd you will not see a large dark stain nucleus Because there is no replication in thereRemember ,they are for the RNA virus

Page 30: VIROLOGY Nasser Al Jehani Njehani10@hotmail.com 1424 - 1425 2003 - 2004 Last edition 2005 - 2006

Page 44: VIROLOGY Nasser Al Jehani Njehani10@hotmail.com 1424 - 1425 2003 - 2004 Last edition 2005 - 2006

In this test,you have to get 2 samples of serum

from the patient’s blood.one from the acute phase

and one from the covalence phase.then you

calculate the titer then you apply
