What is Serratia Odorifera?
What is Serratia Odorifera?
Serratia odorifera biogroup 1 was isolated from the blood and urine of an alcoholic male with cirrhosis and signs of septic shock. The organism is rarely reported to occur in clinical specimens. This is the first case in which the organism was found to be responsible for invasive human infection.
Is Serratia marcescens serious?
S. marcescens has been shown to cause a wide range of infectious diseases, including urinary, respiratory, and biliary tract infections, peritonitis, wound infections, and intravenous catheter-related infections, which can also lead to life-threatening bacteremia.
How do you get Serratia bacteremia?
The main risk factor for Serratia sepsis/bacteremia is hospitalization. Placement of intravenous, intraperitoneal, or urinary catheters and prior instrumentation of the respiratory tract have been identified as risk factors among inpatients.
Is Serratia a pathogen?
Serratia marcescens is an opportunistic, gram negative, nosocomial pathogen which belongs to family, Enterobacteriaceae. It was discovered by Bizio, an Italian pharmacist, in 1819, when he identified it as a cause of the bloody discolouration on cornmeal mush.
Which medications are used in the treatment of Serratia infection?
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 harmful?
Today, Serratia marcescens is considered a harmful human pathogen which has been known to cause urinary tract infections, wound infections, and pneumonia. Serratia bacteria also have many antibiotic resistance properties which may become important if the incidence of Serratia infections dramatically increases.
Is Serratia harmless?
Is Serratia marcescens Gram positive or Gram negative bacteria?
Serratia marcescens (/səˈreɪʃiə mɑːrˈsɛsɪnz/) is a species of rod-shaped Gram-negative bacteria in the family Enterobacteriaceae .
Is serratia bacteria harmful?
At one point in time, serratia marcescens was believed to be a completely harmless organism. Recently, however, scientific research has shown that s. marcescens can be a harmful bacterium. Serratia marcescens is now known to be a common cause of human infections in the respiratory tract, digestive tract, and in wound site infection.
