Browsing: E. Coli

Escherichia coli, commonly abbreviated as E. coli, is a rod-shaped, gram-negative bacterium that is frequently found in the lower intestine of warm-blooded organisms. Most strains of E. coli are harmless and are actually an important part of a healthy human intestinal tract. However, some strains, such as E. coli O157, can cause severe abdominal cramps, diarrhea that may be bloody, and vomiting. Infection typically occurs through ingesting contaminated water or food, or through contact with infected animals or persons. E. coli serves as an important model organism in molecular biology research due to its rapid growth, ease of manipulation, and detailed genetic understanding. It is also widely used in biotechnology and microbiology for the synthesis of recombinant proteins. Understanding E. coli interactions with its hosts can provide insights into both pathogenic and non-pathogenic processes, which can lead to advances in healthcare and food safety.
