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.

Researchers Develop Quantum-AI Platform to Predict Antimicrobial Resistance in Salmonella

SARPLLM leverages large language modeling and quantum algorithms to predict Salmonella AMR, offering robust analysis and user-friendly data visualization tools.

Nutrient Starvation Impedes Antibiotic Efficacy in Salmonella Infections

A new study from the University of Basel, published in Nature, challenges the conventional understanding of antibiotic treatment failure. Rather than attributing such failures to a small population of highly resistant bacteria, the research suggests a different explanation.

Zinc Inhibits Plasmid Transfer in Gut Microbes

Genes responsible for antimicrobial resistance (AMR) can spread from microbe to microbe through circular genetic material called plasmids, and this lateral transfer occurs in the gut. This week in Applied and Environmental Microbiology, researchers in Iowa report that the transmission of some AMR plasmids may be inhibited by a readily available source-;dietary zinc supplements.

Bacteria Can Recode Their Genetics With a Single Flip

Envision being a single cartwheel away from altering looks. The brown locks will turn platinum blond with just one flip. That is similar to what occurs in certain prokaryotes, or single-celled creatures like bacteria when they go through a process known as inversions.

Bad Bacteria Use Electric Signals to Find Entry Points in the Gut

How do bad bacteria find entry points in the body to cause infection? This question is fundamental for infectious disease experts and people who study bacteria.

Researchers Uncover Role of OpgH in Bacterial Cell Shape

In what they labeled a "surprising" finding, Johns Hopkins Medicine researchers studying bacteria from freshwater lakes and soil say they have determined a protein's essential role in maintaining the germ's shape. Because the integrity of a bacterial cell's "envelope" or enclosure is key to its survival, the finding could advance the search for new and better antibiotics.

Few Chicken Products with Highly Virulent Salmonella Strains Responsible for Most Illnesses

Raw poultry is one of the main causes of Salmonella poisoning, which affects thousands of people in the U.S. every year. A new study from the University of Illinois Urbana-Champaign shows that few products with high levels of very virulent Salmonella strains are responsible for most of the illnesses from raw chicken parts.
