A unique homologue of the eukaryotic protein-modifier ubiquitin present in the bacterium Bacteroides fragilis, a predominant resident of the human gastrointestinal tract.

In the complete genome sequences of Bacteroides fragilis NCTC9343 and 638R, we have discovered a gene, ubb, the product of which has 63 % identity to human ubiquitin and cross-reacts with antibodies raised against bovine ubiquitin. The sequence of ubb is closest in identity (76 %) to the ubiquitin gene from a migratory grasshopper entomopoxvirus, suggesting acquisition by inter-kingdom horizontal gene transfer. We have screened clinical isolates of B.

Process evaluation of an out-patient detoxification service.

This paper describes the process evaluation of an out-patient detoxification service (ODS) established by Drug Health Services (DHS) to increase the supervised withdrawal options for substance users in a Sydney metropolitan Area Health Service. The ODS aimed to provide a safe and effective supervised withdrawal to substance users who were at low risk of severe withdrawal, engage those with severe dependence in further treatment and increase the involvement of general practitioners (GPs) in the medical care of ODS clients. During its first 10 months of operation, the ODS received 199 inquiries, assessed 82 individuals and admitted 76 clients for detoxification.
