ERWINIA PSIDII
| Class: | Gamma Proteobacteria |
| Genus: | Erwinia |
| Species: | Erwinia psidii |
| Description: | Erwinia psidii is a Gram-negative bacterium and a phytopathogen of the Common Guava (Psidium guajava),causing rot in branches, flowers and fruits. Recently it was demonstrated that this species produces two acyl-homoserine lactones (S-(-)-N-hexanoyl-and N-heptanoyl-homoserine lactone), widely recognized bacterial quorum sensing signaling substances, and employed in bacterial cell-to-cell communication systems. There is no data found in genome and 221 Nucleotide sequences are available for this ogranism.

| Synonyms: | Erwinia psidii(Neto et al.1988) |
| Source: | Erwinia psidii was first detected in Valindos and Pindamohangaba counties of Sao paulo state,Brazil. The occurrence of E. psidii is limited to Brazil. |
| Pathogenicity: | Pathogenic to guava (Psidium guajava L.) causing a die-back of twigs and branches, characterized by a collapse of the vascular tissue. In artificial inoculations, the bacterium was also pathogenic to strawberry guava (Psidium cattleianum Lam.), jambolana (Eugenia jambolana Lam.), and “mela- leuca” (Melaleuca viridiflora Brogn. and Gris.), and to all members of the Myrtaceae family. A new shoot and stem disease of Eucalyptus species caused by Erwinia psidii. |
