European otter

Sleek semi-aquatic mustelid found along clean rivers, streams, and coastlines across Europe and Asia. European otters can reach 1.3 meters in length and are highly skilled fish hunters, using sensitive whiskers to detect prey movements. Requiring unpolluted water with abundant fish, they are an indicator species for freshwater ecosystem health. Once nearly extinct in Western Europe from hunting and pollution, populations have recovered significantly following water quality improvements.

Staphylococcus haemolyticus is a coagulase-negative, Gram-positive coccus known for its broad antibiotic resistance and occasional opportunistic infections in immunocompromised patients. It is a common commensal on human skin and mucous membranes worldwide. This bacterium can cause prosthetic device infections and bacteremia in hospital settings.
