Acanthamoeba is a microscopic, free-living amoeba, or amoeba (single-celled living organism), that can cause rare but serious eye, skin, and central nervous system infections. The amoeba is found worldwide in the environment in water and soil. The amoeba can spread to the eyes through the use of contact lenses, cuts or wounds in the skin, or by being inhaled into the lungs. Most people will be exposed to Acanthamoeba in their lifetime, but very few will become ill from this exposure

Over a billion of mostly third world people are infected with a roundworm known as ascarids. Ascarids are tiny parasites that infect the intestinal tract of vertebrates. Movement of the larvae into the brain or other parts of the body can prove fatal. Space-based research is providing new hope in combating these parasitic worms. Ascarids are dependent upon a substance known as malic enzyme to regulate certain bodily functions. A new drug designed to interfere with normal functioning of malic enzyme should prove deadly to ascarids. The Center for Macromolecular Crystallography, along with the University of North Texas grew malic enzyme crystals on the USML-1 Spacelab mission. Although these crystals proved to be smaller than ground based ones, they were more perfectly formed, therefore producing better data for drug design.

This scanning electron micrograph (SEM) depicts a flagellated Vibrio vulnificus bacterium, Mag. 13184x. Vibrio vulnificus is a bacterium in the same family as those that cause cholera. It normally lives in warm seawater and is part of a group of vibrios that are called halophilic because they require salt. V. vulnificus can cause disease in those who eat contaminated seafood or have an open wound that is exposed to contaminated seawater. Among healthy people, ingestion of V. vulnificus can cause vomiting, diarrhea, and abdominal pain. In immunocompromised persons, particularly those with chronic liver disease, V. vulnificus can infect the bloodstream, causing a severe and life-threatening illness characterized by fever and chills, decreased blood pressure (septic shock), and blistering skin lesions. V. vulnificus bloodstream infections are fatal about 50% of the time. See image n0831905 on the site.
