Population and resistance patterns of Salmonella Typhimurium and Staphylococcus aureus biofilms to sublethal chemical disinfection under mono-and dual-species multi-strain conditions
To evaluate the possible influence of bacterial interactions encountered in mono- and dual-species multi-strain biofilms of Salmonella Typhimurium (ST) and Staphylococcus aureus (SA) on: (i) the ability of strains to develop biofilm, and (ii) their subsequent resistance to sublethal chemical disinfection
Overexpression of a Glutathione S-Transferase gene from P. vulgaris L. Improves salt stress Tolerance in Transgenic Tobacco Plants
Glutathione S-transferases (GSTs) are multifunctional proteins and forms major part, of plant cellular detoxification system and antioxidant enzyme network. Previously, a novel GST gene PvGSTU3-3 has been isolated from roots of Phaseolus vulgaris L. plants. The isoenzyme shows high antioxidant catalytic function and acts as hydroperoxidase, thioltransferase, and dehydroascorbate reductase. In the present study, with a view to investigate the biological function of PvGSTU3-3 a constitutive plant overexpression vector of PvGST3-3 was constructed and transferred into tobacco (Nicotiana tabacum. L. cv Xanthi) plants via A. tumefaciencs. The PvGSTU3-3 gene was successfully integrated into the genome of the transgenic tobacco lines as confirmed by Real time PCR and expressed in the transformants, validated through quantitative reverse transcription PCR. Three tobacco transgenic lines overexpressing PvGSTU3-3 tested for their salt tolerance (200mM NaCl) under in vitro conditions. All lines were more tolerant compared to wt plants, as demonstrated by the increased root length. These results suggest that PvGSTU3-3 isoenzyme can mediate physiological pathways that enhance salt stress tolerance
Strain effect on the heterogeneity of individual-cell growth kinetics of Salmonella Typhimurium
The present study showed that the variability of individual-cell growth kinetics may differ among strains of S. Typhimurium. The results provide useful quantitative information for incorporating strain variability and heterogeneity in individual-cell behavior in stochastic growth models and risk assessment studies
Single-cell growth kinetic behavior of pathogenic bacteria in the presence of microbial supernatants containing autoinducer-2 signal compounds
The findings of this study constitute preliminary data on the role of QS compounds on the single-cell growth behavior of important pathogens, knowledge that maybe useful in understanding the mechanisms underlying their behavior as well as in developing strategies for their control in situ

Population dynamics of Staphylococcus aureus and Salmonella Typhimurium in a laboratory medium and rocket extract
In the present study, the growth of Staphylococcus aureus and Salmonella Typhimurium on different growth media was studied. For this purpose, a growth medium (Luria – Bertani broth, LB) and extract from rocket, were inoculated with Staphylococcus aureus strain COL (MRSA) and Salmonella Typhimurium (CDC 6516-60). After the inoculation, the samples were incubated at 20°C
