R131

R131 is a designation that can refer to several different entities, most notably a particular strain of bacteria and a proposed route number.

In microbiology, R131 refers to a specific strain of the bacterium Escherichia coli (E. coli) known as E. coli O131. This strain has been identified in various environmental and clinical settings. While many strains of E. coli are harmless commensals, some can cause disease. Research into specific strains like R131 often focuses on their genetic makeup, antibiotic resistance patterns, and potential pathogenicity. Understanding these characteristics is crucial for public health and clinical treatment strategies.

Additionally, R131 has been proposed as a route number in some transportation planning contexts. For instance, it has appeared in discussions regarding potential road or transit line designations. These proposals are typically part of larger infrastructure development or traffic management plans. The specifics of such a route would depend on the geographical location and the authority proposing the designation. Information regarding R131 as a route number would generally be found in official transportation documents or planning reports related to the specific region.
