A survey was undertaken of the occurrence, serotype, antimicrobial sensitivity and plasmid content of members of the tribe Proteeae in the environment of two @entity291 -rearing units in the county of Avon in South West England. Examples of the following species were found: @entity5609 , Prot. vulgaris, Prot. vulgaris Biogroup 2, @entity11889 , @entity11477 , Prov. alcalifaciens and Prov. rettgeri. A wide range of serotypes was found, many having been previously reported from nosocomial isolates. A total of 15% of isolates carried plasmids; six pairs of isolates were identified which had identical serotypes but different patterns of plasmid carriage. The antimicrobial sensitivity of the isolates was generally similar to isolates of Proteeae from @entity1 . Although no truly @entity4028 -resistant isolates were found, some isolates of Prov. stuartii and Prov. rettgeri had MIC's higher than the other isolates to @entity801 and @entity5153 , suggesting the presence of low levels of the enzyme AAC 2'. The study demonstrates that there is a considerable diversity of species and types of Proteeae associated with @entity291 and their environment. It seems likely that a potential cause of colonization of the @entity1 gut by Proteeae is the consumption of meat.
