S. marcescens is a motile organism and can grow in temperatures ranging 5–40 °C (41–104 °F) and in pH levels ranging from 5 to 9. It is differentiated from other Gram-negative bacteria by its ability to perform casein hydrolysis, which allows it to produce extracellular metalloproteinases which are believed to function in cell-to-extracellular matrix interactions.
Operation Sea-Spray was a 1950 U.S. Navy secret biological warfare experiment in which Serratia marcescens and Bacillus globigii bacteria were sprayed over the San Francisco Bay Area in California, in order to determine how vulnerable a city like San Francisco may be to a bioweapon attack, killing at least one American and sickening at least 10 more.
S. marcescens is frequently found in showers, toilet bowls, and around wet tiles as a pinkish to red biofilm but only causes disease in immunocompromised individuals. Aside from S. marcescens , some rare strains of the Serratia species – S. plymuthica , S. liquefaciens , S. rubidaea , and S. odoriferae – have been shown to cause infection ...
This either alone or in combination with bacterial infection destroys the gut tissue. Bacterial pathogens contributing to infectious flaccherie are Serratia marcescens, and species of Streptococcus and Staphylococcus in the form known as thatte roga. In the nineteenth century, flacherie resisted the efforts of Louis Pasteur. [2]
In a story ripe for fright matching Alfred Hitchcock's famous shower scene, researchers at the University of Colorado at Boulder have discovered that taking a shower can deliver a face full of ...
S. marcescens on an agar plate. The pathogen responsible is believed to be Serratia marcescens, a common intestinal bacterium found in humans and other animals. [1] [6] This is the first time it has been linked to the death of coral. [7]
Ulcerative white spot disease is caused by vibrio bacteria. [4] [11] Growth anomalies, like enlarged polyps, are caused by microorganisms. [4] An example of this is a trematode infecting a finger coral (Porites compressa). [11] Brown jelly disease is caused by ciliate protozoans. [4] Red slime algae is a kind of cyanobacteria that can infect ...
Serratia marcescens has an ampC gene which can be induced by exposure to antibiotics such as cephalosporins. Thus, culture sensitivities may initially indicate appropriate treatment which fails due to bacterial response. Enterobacter as a group also have an inducible ampC gene. Enterobacter may also develop resistance by acquiring plasmids.
