A ball and stick model of a molecule of Human Interferon. Interferons are proteins important in the working of the immune system and are produced in large numbers in the presence of viruses, bacteria, tumors and parasites.  Interferons are used in drugs to combat cancer, multiple sclerosis, hepatitis B and C and other diseases. Isolated on white.

The human immunodeficiency virus single-stranded RNA genome is converted into double-stranded DNA by the viral reverse transcriptase and then the DNA is integrated in the DNA of an infected human cell. The reverse transcriptase is one of the main targets to disrupt the virus multiplication through an inhibitor. There are nucleoside and nucleotide inhibitors and non nucleoside analogue inhibitors.

Blastomycosis is a fungal infection caused by inhaling Blastomyces dermatitidis spores. If it involves only the lungs, it is called pulmonary blastomycosis. Only about half of people with the disease have symptoms, which can include fever, cough, night sweats, muscle pains, weight loss, chest pain, and feeling tired.
