Xylophilus ampelinus

Xylophilus ampelinus (syn. Xanthomonas ampelina and Erwinia vitivora) is a species of bacteria that can cause plant disease. It is available from the NCPPB in the United Kingdom and other international culture collections such as ICMP in New Zealand, and LMG/BCCM in Belgium. Xylophilus ampelinus was known as Xanthomonas ampelina until it was renamed in 1969 by C.G. Panagopoulos. The type strain was isolated on 5 March 1966 by C.G. Panagopoulos from grape vine (Vitis vinifera var. Sultana) in Greece and was deposited into the NCPPB in 1968 from where it has been distributed to other culture collections for research and diagnostic reference material. Published references to the organism currently include "Panagopoulos, C.G. 1969. Annls. Inst. Phytopath. Benaki. N.S. 9: 59". Xylophilus ampelinus is a rod-shaped bacterium that is considered slow growing at ambient temperatures of 25 degrees Celsius. It is gram negative and develops round, yellow colonies when grown on nutrient agar and after extended growth, becomes filamentous. The bacterium is catalase positive, Kovacs negative, urease positive, produced H2S from cysteine, and did not produce acid from any carbohydrate media.
