Salmonella News and Research

RSS

Salmonella is actually a group of bacteria that can cause diarrheal illness in humans. They are microscopic living creatures that pass from the feces of people or animals to other people or other animals. There are many different kinds of Salmonella bacteria. Salmonella serotype Typhimurium and Salmonella serotype Enteritidis are the most common in the United States. Salmonella germs have been known to cause illness for over 100 years. They were discovered by an American scientist named Salmon, for whom they are named.

Cornell scientists discover new 'jumping' superbug gene

While sifting through the bacterial genome of salmonella, Cornell University food scientists discovered mcr-9, a new stealthy, jumping gene so diabolical and robust that it resists one of the world's few last-resort antibiotics.
