Cultured Mumps Virions

This digitally-colorized transmission electron micrograph (TEM) depicts numerous Chikungunya virus particles, which are composed of a central dense core that is surrounded by a viral envelope. Each virion is approximately 50nm in diameter. Chikungunya virus is transmitted to people by mosquitoes. The most common symptoms of chikungunya virus infection are fever and joint pain. Other symptoms may include headache, muscle pain, joint swelling, or rash. Outbreaks have occurred in countries in Africa, Asia, Europe, and the Indian and Pacific Oceans. In late 2013, chikungunya virus was found for the first time in the Americas on islands in the Caribbean. Chikungunya virus is not currently found in the United States. There is a risk that the virus will be imported to new areas by infected travelers. There is no vaccine to prevent or medicine to treat chikungunya virus infection. Travelers can protect themselves by preventing mosquito bites. When traveling to countries with chikungunya virus,

Using trichrome staining, this photomicrograph depicts a trophozoite of the unicellular parasite, Entamoeba histolytica. Colored purple, the trophozoite, seen here in the center of the micrograph, is one of the phases of the life cycle that a protozoan organism goes through, as it matures, and is the active feeding phase of its growth . Other particles surrounding the trophozoite represent debris from the blade specimen. CDC/DPDx - Melanie Moser

KENNEDY SPACE CENTER, FLA. - Pictured is one of the microcapsules removed from the Commercial ITA Biomedical Experiments payload recovered during the search for Columbia debris. The drug delivery system and spaceflight hardware was developed jointly by JSC, the Institute for Research Inc. and Instrumentation Technology Associates Inc. to conduct microencapsulation experiments under microgravity conditions. This microcapsule contains an antibiotic for treating deep resistant pulmonary infections. Dr. Dennis Morrison, senior biotech project scientist, is principle investigator on microencapsulation and urokinase crystal growth.
