Legionella - pathogenic Gram negative bacterium. Acquired its name after a July, 1976 outbreak of a then-unknown "mystery disease" sickened 221 persons, causing 34 deaths. The outbreak was first noticed among people attending a convention of the American Legion - an association of U.S. military veterans

Toxic marine Dinoflagellate (Karenia brevis) Toxic marine Dinoflagellate (Karenia brevis) that causes red tide. This gymnodinioid dinoflagellate has an equatorial groove containing one undulating flagellum and a second flagellum that trails behind the cell. They produce the brevetoxin which affects the central nervous system of fish, and people can become ill with neurotoxic shellfish poisoning when they eat shellfish that have accumulated brevetoxin.

Giardiasis is a diarrheal illness caused by the parasite Giardia intestinalis (also known as Giardia lamblia or Giardia duodenalis). A parasite is an organism that feeds off of another to survive. Giardiasis is a global disease. It infects nearly 2% of adults and 6% to 8% of children in developed countries worldwide. Nearly 33% of people in developing countries have had giardiasis. In the United States, Giardia infection is the most common intestinal parasitic disease affecting humans.

Penicillium mold spores and hyphae. Some things considered disgusting are beautiful as microscopic imagery.

Scientists have mapped which bacteria normally live in or on us, calculating that healthy people can share their bodies with more than 10,000 species of microbes.

Most people know the four blood types, A, B, AB, and O but lesser known are the Japanese personality traits associated with each blood type. (Hmm ???) This infographic contains blood related facts such as blood donation requirements, diseases requiring blood donations, and more.

Clostridium difficile: Emerging Issues and Treatments. Clostridium difficile infection is an important cause of intestinal disease, primarily affecting hospitalized patients exposed to antibiotics. Infection has been associated with prolonged hospital stays and excess healthcare expenditures. Recent changes in epidemiology of this disease show a rise in community-acquired cases in people outside the hospital settings without traditional risk factors.

Swine flue is caused by various swine viruses and also known as novel influenza A (H1N1). Every year many people suffer with swine flu.

Gonorrhea, once a minor illness, is developing resistance to the last category of drugs that still works against it and could become untreatable - common human sexually transmitted infection caused by the bacterium "Neisseria gonorrhoeae."
