Estimation of Staphylococcus aureus growth parameters from turbidity data: Characterization of strain variation and comparison of methods

Article Abstract:

The objective of a study is the identification of the best approach for determining the growth parameters based on turbidity data and use of a bioscreen instrument and characterizing variability in growth parameters of 34 Staphylococcus aureus of different biotypes isolated from broiler carcasses. Estimation of the growth parameters is done by fitting primary growth models to turbidity growth curves or detecting times of serially diluted cultures either directly or by using an analysis of variance (ANOVA) approach.

Universal sample preparation method for characterization of bacteria by matrix-assisted laser desorption ionization-time of flight mass spectrometry

Article Abstract:

A universal method is developed for bacterial identification by matrix-assisted laser desorption ionization-time of flight mass spectrometry. The method is found to be simple, rapid and easy to perform, has excellent reproducibility and is suitable for the construction of a mass spectrum fingerprinting datadase, which helps in fast bacterial identification via database searching.
