“…This may have had some bearing on results obtained and makes comparison between methods more difficult. Overall however, it was clear that all three rapid methods gave a higher detection of salmonellae than conventional culture (Smith et al 1991).…”

Three rapid methods, an impedance method (Malthus 2000 Analyzer), a colorimetric DNA hybridization method (Gene-Trak) and a post-enrichment enzyme-linked immunosorbent assay (Salmonella-Tek) were compared with conventional culture for the detection of Salmonella in poultry feeds, and in fluff and dust samples from poultry housing. The percentage positive samples for Salmonella by each of the methods were 25.5% for conventional culture, 38.4% for the Malthus, 28.9% for the Gene-Trak and 28.5% for the Salmonella-Tek. By any method 60/153 (39.2%) of the samples tested were positive on confirmed culture.

“…For quantitative studies with salmonellas and other microorganisms the impedimetric technique is now a well established rapid method (Zindulis 1984;Gibson 1987;Bullock and Frodsham 1989;Watson-Craik et al 1989;Bolton 1990;Smith et al 1991). Unlike the standard plate count technique, impedance microbiology monitors microbial metabolism in a real time modus.…”

In order to study strain-specific differences in their growth behaviour at different, and particularly lower, temperatures, generation times for 45 strains of Salmonella enteritidis isolated from food were determined impedimetrically over a temperature range from 7 to 42 degrees C. In practical terms, 7 degrees C is the minimum requirement for Salm. enteritidis growth, and generation time variability increases markedly as this temperature is reached. Reports in the literature describing psychrotrophic behaviour and multiplication at lower temperatures cannot be confirmed. Generation time variability increased as temperature moved away from the optimal range with variation coefficients tending to rise as temperature fell. The great variability of multiplication parameters near the growth limit found in Salm. enteritidis may also be a characteristic of other bacterial species. It is therefore imperative to commence studies on larger numbers of strains to allow prediction of their behaviour at lower temperatures.
