CK4

CK4 refers to a specific strain of the bacterium *Escherichia coli* (E. coli). *E. coli* is a common bacterium found in the lower intestine of warm-blooded organisms. While most strains of E. coli are harmless and even beneficial, some strains can cause illness. CK4 is one such strain that has been identified and studied, primarily in research settings.

Research involving E. coli strains like CK4 often focuses on understanding the mechanisms of infection, antibiotic resistance, and the development of new diagnostic tools or treatments. The specific characteristics of CK4, such as its genetic makeup or virulence factors, would determine its relevance in particular studies. For example, it might be used as a model organism to investigate how certain E. coli strains adhere to host cells or produce toxins.

Information about specific strains like CK4 is typically found in scientific literature, including peer-reviewed journals and databases that catalog microbial strains. These sources provide details about the strain's origin, its genetic profile, and the experimental contexts in which it has been utilized. The scientific community uses such characterized strains to advance knowledge in microbiology, infectious diseases, and related fields.
