Marburg hemorrhagic fever (Marburg HF) is a rare, severe type of hemorrhagic fever which affects both humans and non-human primates. Caused by a genetically unique zoonotic (that is, animal-borne) RNA virus of the filovirus family, its recognition led to the creation of this virus family. The fi... Read More

Campylobacter bacteria are the number-one cause of food-related gastrointestinal illness in the United States. To learn more about this pathogen, ARS scientists are sequencing multiple Campylobacter genomes. This scanning electron microscope image shows the characteristic spiral, or corkscrew, s... Read More
This microscopy image provided by Dr. Carl June, shows immune system T-cells, center, binding to beads which cause the cells to divide. The beads, depicted in yellow, are later removed, leaving pure T-cells which are then ready for infusion to the cancer patients. Scientists are reporting the fi... Read More

Colorized transmission electron micrograph of Avian influenza A H5N1 viruses (seen in gold) grown in MDCK cells (seen in green).
Avian influenza A viruses do not usually infect humans; however, several instances of human infections and outbreaks have been reported since 1997. When such infecti... Read More

Individual bacteria in this photo are oblong and colored brown. As an alternative to using antibiotics for fighting E. coli infections in newborn and weaned pigs, scientists are finding promising results from introducing mixes of beneficial bacteria, obtained from other pigs, into the gut of you...
