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
At East Diamante volcano (195 m, 640 ft depth), tropical fish swim above boulders covered with bacterial mat, which indicates the presence of hydrothermal venting. These fish live in the reef community above and are about 15 cm long (6 in). Read More
Listeria monocytogenes has a particular tropism for the central nervous system. To gain knowledge about the immune response elicited by L. monocytogenes in the brain, we used a rat ex-vivo organotypic nervous system culture as a model for Listeria infection. Brain sections were maintained severa... Read More
