Is Serratia Gram positive or negative?
Serratia species are gram-negative bacilli of the Enterobacteriaceae group of bacteria, although they are not a common component of healthy human fecal flora.
What Gram stain is Serratia?
Serratia marcescens is a gram-negative rod-shaped facultatively anaerobic bacterium that is extremely motile. An S. marcescens gram stain shows short, pink-colored dots, as seen below.
Where is Serratia Fonticola found?
First described by Gavini et al. in 1979, Serratia fonticola is a member of the Enterobacteriaceae family found in a wide array of environments, including drinking water, soil and sewage [1], [2].
What is the morphology of Serratia marcescens?
Serratia marcescens is a Gram-negative, facultatively anaerobic, rod-shaped bacterium belonging to the family Enterobacteriaceae.
What is Serratia susceptible to?
Serratia infections should be treated with an aminoglycoside plus an antipseudomonal beta-lactam, as the single use of a beta-lactam can select for resistant strains. Most strains are susceptible to amikacin, but reports indicate increasing resistance to gentamicin and tobramycin.
Is Serratia contagious?
Nosocomial transmission may occur by hand contact from hospital personnel and other patients. Fomites may also spread Serratia. INCUBATION PERIOD: Unknown. COMMUNICABILITY: Serratia may be directly transmitted from person-to-person, but rates are unknown 3.
Can you be colonized with Serratia?
Colonization by Serratia spp. was associated with yearly age at admission, long ICU stay and high mortality. Both the respiratory and digestive tracts were frequently colonized. Our findings do not support the contention that the digestive tract is more important as reservoir than the respiratory tract in neonates.
