What color is Serratia marcescens?
red
As you have observed, this bacterium produces a bright red pigment (which historically has even been mistaken for blood) when grown at temperatures below 35-37C, but does not produce this pigment at higher temperatures, resulting in a pale off-white color.
What color colony is Serratia marcescens?
red colonies
On blood agar and some other media, S. marcescens produces red colonies. On CT agar, colonies of Serratia spp. are small and slightly bluish-white.
Are Serratia motile?
S. marcescens is a motile organism and can grow in temperatures ranging from 5–40 °C and in pH levels ranging from 5 to 9.
What is the genus of Serratia?
Serratia
Serratia marcescens/Genus
Where do you find Serratia?
It is commonly found in the respiratory and urinary tracts of hospitalized adults and in the gastrointestinal systems of children. Due to its abundant presence in the environment, and its preference for damp conditions, S.
Is Serratia an Enterobacter?
The gram-negative bacteria Klebsiella, Enterobacter, and Serratia are closely related normal intestinal flora that rarely cause disease in normal hosts. Diagnosis is by culture. Treatment is with antibiotics.
What is prodigiosin to Serratia marcescens?
Prodigiosin is a red pigment produced as a secondary metabolite by Serratia marcescens, characterized with unique tripyrrole structure which is regarded as responsible for its reported pharmacological characteristics as anti-cancer, anti-microbial, anti-oxidant and immunosuppressant [4] and it s unique application as a …
What is the origin of CHO-K1 cells?
The CHO-K1 cell line was derived as a subclone from the parental CHO cell line initiated from a biopsy of an ovary of an adult Chinese hamster by T. T. Puck in 1957.
