Serratia marcescens as a pathogen of tsetse flies.
When applied to the ears of rabbits used as hosts for tsetse flies, the bacterium Serratia marcescens produced significant mortality in populations of Glossina m. morsitans and G. pallidipes. After being ingested during the blood meal, cells of S. Marcescens multiplied in the intestine of the flies and entered the hemocoel. Using the brush method of applying the bacterium, 100% mortality of bot...
متن کاملSerratia marcescens: an unusual pathogen associated with snakebite cellulitis.
This study reports a case of Serratia marcescens cellulitis following a snakebite in a 50-year-old woman. The bite was on the dorsum of the right hand with symptoms of envenomation. She developed swelling and cellulitis with tissue necrosis. Wound debridement was performed. Pus and tissue biopsy cultures yielded Serratia marcescens sensitive to fluoroquinolones, aminoglycosides, third-generati...

متن کاملHost behaviour and exposure risk in an insect-pathogen interaction.
1. Studies of variability in host resistance to disease generally emphasize variability in susceptibility given exposure, neglecting the possibility that hosts may vary in behaviours that affect the risk of exposure. 2. In many insects, horizontal transmission of baculoviruses occurs when larvae consume foliage contaminated by the cadavers of virus-infected conspecific larvae; so, host behaviou...
متن کاملThe Insect Pathogen Serratia marcescens Db10 Uses a Hybrid Non-Ribosomal Peptide Synthetase-Polyketide Synthase to Produce the Antibiotic Althiomycin
There is a continuing need to discover new bioactive natural products, such as antibiotics, in genetically-amenable micro-organisms. We observed that the enteric insect pathogen, Serratia marcescens Db10, produced a diffusible compound that inhibited the growth of Bacillis subtilis and Staphyloccocus aureus. Mapping the genetic locus required for this activity revealed a putative natural produc...
