Mononucleosis - view of the throat

Infectious mononucleosis causes a sore throat, enlarged lymph nodes, and fatigue. The throat may appear red and the tonsils covered with a whitish material. Mononucleosis and severe streptococcal tonsillitis appear quite similar. Unless there are other findings to suggest mononucleosis, a throat culture and blood studies may be necessary to make an accurate diagnosis.

Infectious mononucleosis is caused by the Epstein-Barr virus. In teenagers and young adults, there is frequently a sore throat and red tonsils with whitish spots (exudate), as seen in this picture. Enlarged lymph nodes and fatigue are also common.

Antibodies
Antibodies

Antigens are large molecules (usually proteins) on the surface of cells, viruses, fungi, bacteria, and some non-living substances such as toxins, chemicals, drugs, and foreign particles. The immune system recognizes antigens and produces antibodies that destroy substances containing antigens.
