Summary In a previously reported apparent outbreak of infection due to Acinetobacter calcoaceticus on a Regional Burns Unit in which both clinical and environmental isolates were available for study, investigations of the organisms by electrophoretic

Whole cell samples from cultures of Staphylococcus aureus, S. hominis, S. epidermidis and Streptococcus pyogenes were analysed by pyrolysis mass spectrometry and the results were compared with Py-MS-derived analyses of samples of DNA extracted from t

To assess the utility of PCR-enzyme immunoassay (EIA) for diagnosis of acute infection with C pneumoniae, we compared tissue culture, PCR-EIA, direct fluorescent-antibody (DFA) stain, and serology in studies with 56 patients with respiratory symptoms

Verocytotoxin (VT)-producing and VT-non-producing strains of Escherichia coli of four different serogroups were characterised by pyrolysis-mass spectrometry (Py-MS). Py-MS spectral data were used to train artificial neural networks (ANNs) which then

Synthetic oligonucleotides of known base sequence and of 20 base lengths were compared using pyrolysis—mass spectrometry (PyMS). The data were then analysed by principal component and canonical variate analysis. The results showed that PyMs i

Aeromonas sp., grown in tryptone soya broth supplemented with yeast extract, 0.6%, pH 7.5, and incubated with agitation at 100 oscillations/min for 15 h at 37 degrees C produced optimal amounts of beta-haemolysin and cytotonic enterotoxin. More prolo

SUMMARY: Fifty-eight isolates of Clostridium difficile from two distinct outbreaks were examined for inter-strain similarity by pyrolysis mass spectrometry (PMS). The first outbreak began on a geriatric acute unit and spread to a long stay geriatric

SUMMARYIn 1990 we reported that milk bottles pecked by jackdaws and magpies were a probable source of human Campylobacter infection. During April to June 1990 an extended study of Campylobacter infections was carried out in the Gateshead area. Prior

In the UK the Public Health Laboratory Service distributes simulated water samples with low or moderate counts of organisms, usually coliforms. Sometimes these include small numbers of E. coli. Statistical analysis can be used to assess the performan

Sixteen isolates of penicillin-resistant Streptococcus pneumoniae (penicillin-resistant pneumococci, PRP) serotype 23 with identical antibiograms were examined by pyrolysis mass spectrometry (PYMS) as a possible method of rapid inter-strain compariso
