1. Epstein-Barr virus (mononucleosis)
A virus in the family Herpesviridae which infects humans. It causes infectious mononucleosis, which is characterized by debility, fever, sore throat, enlarged lymph nodes, and an increase in white blood cell count. This virus is transmitted mainly via saliva and is associated with carcinoma s of the nasal passages and throat and with Burkitt's lymphoma .

2. Guillain-Barre Syndrome (acute idiopathic polyneuritis)
A rare disease in which the body's immune system attacks the nerves of the peripheral nervous system , damaging the protective myelin sheath s surrounding the nerves and sometimes damaging the nerve axon s. Symptoms have a range of severity and can include abnormal sensations (such as numbness, pins and needles, vibrations, etc.), muscle weaknesses (due to the destruction of the nerves which carry signals to the affected muscles), aches and pains, and paralysis. The cause of Guillain-Barre Syndrome is unknown; often it is triggered by a virus infection (like hepatitis , mononucleosis , etc.). The disease occurs in both sexes and at any age. Treatment for the disease consists of treating the different symptoms as they arise and rehabilitation. Most patients (around 90%) recover without serious long-term disabilities between six months and two years after the syndrome begins. The 1-5% death rate is usually due to respiratory or cardiovascular complications.

3. Herpesviridae (herpesviruses, herpes viruses)
Family of DNA -containing virus es that infect a wide range of vertebrates; in humans, members of this family are responsible for chickenpox , oral and genital herpes , and mononucleosis . Different types of human herpesviruses: * Type 1 herpes simplex: causes cold sores of the mouth * Type 2 herpes simplex: causes genital herpes * Type 3: is the varicella-zoster virus -- causes chickenpox and herpes zoster * Type 4: is the Epstein-Barr (EB) virus -- causes infectious mononucleosis * Type 5: is the cytomegalovirus (CMV) * Type 6: causes exanthema subitum and hepatitis * Type 7: may cause Kaposi's sarcoma in AIDS patients.

4. Infectious mononucleosis screen
This is the measurement of the so-called heterophil antibody. Heterophil antibodies are completely adsorbed by bovine red blood cells but not by guinea pig kidney cells. This feature distinguishes the heterophil antibodies due to IM from other causes. Monospot is the name given to a particular arrangement to test for the presence of heterophil antibody. Monospot is usually positive within four weeks after onset of the clinical symptoms. Titers of antibodies against Epstein Barr viral capsid antigen (VCA) and nuclear antigen (EBNA) are elevated.

5. Mononucleosis (infectious mononucleosis)
mononucleosis is an infection of Epstein Barr virus. Incubation period is 5 to 7 weeks. Symptoms include headache, generalized malaise and fatigue, sore throat, fever, and enlarged cervical lymph nodes. CBC done during the first week of illness shows granulocytopenia with normal white cell count. Thereafter, the white blood cell count increases steadily reaching as high as 50,000 mainly due to increases in lymphocyte count. Heterophil antibodies and Monospot tests are positive. The lymphocytes in IM have large vacuole s, foamy cytoplasm and dark chromatin in the nucleus , thus named "atypical lymphocytes".
