Serratia marcescens

An opportunistic bacterium that causes septicemia and pulmonary disease, esp. in immunocompromised patients, and is found in water, soil, milk, and stools. In the proper environment, the organism will grow on food and produce the red pigment prodigiosin.

Isolated S. marcescens strains were susceptible in 75% of cases to 3rd generation cephalosporins and all susceptible to imipenem, to ciprofloxacin, and to aminoglycosides (amikacin and gentamicin), but all were resistant to colistin (Table 2).
There are reports in the scientific literature which correlate the ability of strains of S. marcescens, recognized as opportunistic pathogen, to resist the presence of heavy metals and biocides, with concomitant multiresistance to antibiotics (Jafarzade, Mohamad, Usup, & Ahmad, 2012; Nageswaran, Ramteke, Verma, & Pandey, 2012).
