Serratia marcescens is a mesophilic bacterium with optimal growth ranging from 25 degree Celsius to 45 degree Celsius. To obtain better results, temperature must be kept at 37 degrees Celsius.
Room temperature.
Serratia marcescens produces a compound called prodigiosin that binds iron. The production of this pigment is increased at room temperature which gives the bacterial colonies a red pigment.
Serratia marcescens incubated at 37 degrees Celsius will have almost a clear pigmentation. However, when S. marcescens is incubated at 25 degrees Celsius it will produce a very distinct red color.
I am studying this subject in my microbiology class now. Serratia (Serratia marcescens is the bacteria that is found in cathers, saline solutions other non sterile supplies. This can often lead to urinary and respiratory tract infections.
E.coli shows positive result for catalase test..staphylococcus aureus and serratia marcescens too..pseudomonas and klebsiella does not give any vigorous bubbling therefore, it shows negative result
No. The reason is, Chromogenic microorganisms may produce intracellular pigments that are responsible for the coloration of the organisms as seen in surface colonies. Other organisms produce extracellular soluble pigments that are excreted into the medium & that also produce a color. BUT........ most organisms, however, are nonchromogenic & will appear white to gray. ~jmata Microbiology 205 lab manual question. ~

bacillus
No, it is infectious.
My Dad has had Serratia marcescens for 5 months and no antibiotic is getting rid of it. Can he infect his family by coughing?
Serratia genus as a whole is dnase positive.
A healthy immune system keeps the Serratia marcescens in check simply by keeping you healthy and warning your body if there is anything wrong with your Serratia Marcenscens.
Serratia Marcescens is a form of bacteria. It is frequently involved in urinary tract and wound infections. Creepy as it is, this bacteria can be found in parts of the teeth.
