Potential Impact of the Resistance to Quaternary Ammonium Disinfectants on the Persistence of Listeria monocytogenes in Food Processing Environments.

Frontiers in microbiology

Martínez-Suárez JV, Ortiz S, López-Alonso V.
PMID: 27199964
Front Microbiol. 2016 May 02;7:638. doi: 10.3389/fmicb.2016.00638. eCollection 2016.

The persistence of certain strains of Listeria monocytogenes, even after the food processing environment has been cleaned and disinfected, suggests that this may be related to phenomena that reduce the concentration of the disinfectants to subinhibitory levels. This includes...

Water deficit effects on solute contribution to osmotic adjustment as a function of leaf ageing in three durum wheat (Triticum durum Desf.) cultivars performing differently in arid conditions.

Plant science : an international journal of experimental plant biology

Plant Sci. 2001 Mar;160(4):669-681. doi: 10.1016/s0168-9452(00)00443-x.

A greenhouse study was carried out using three durum wheat (Triticum durum Desf.) cultivars differing in their field performances under arid conditions (Kabir 1, poor yield stability; Omrabi 5, high yield stability and Haurani, landrace well adapted to drought)....

Novel teststrip with increased accuracy.

Fresenius J Anal Chem. 2000 Sep-Oct;368(2):203-7. doi: 10.1007/s002160000393.

A new type of a simple and cheap teststrip for liquid samples is described. It is based on microchromatography or microtitration on a porous, capillary-active substrate (e.g., filter paper or a similar absorbent material). In case of microchromatography an...

Solutes contributing to osmotic adjustment in cultured plant cells adapted to water stress.

Plant physiology

Handa S, Bressan RA, Handa AK, Carpita NC, Hasegawa PM.
PMID: 16663309
Plant Physiol. 1983 Nov;73(3):834-43. doi: 10.1104/pp.73.3.834.

Osmotic adjustment was studied in cultured cells of tomato (Lycopersicon esculentum Mill cv VFNT-Cherry) adapted to different levels of external water potential ranging from -4 bar to -28 bar. The intracellular concentrations of reducing sugars, total free amino acids,...

Cation exchange contribution to the retention of specific quaternary ammonium compounds in reversed-phase high-performance liquid chromatography.

Journal of pharmaceutical and biomedical analysis

Reynolds DL, Repta AJ, Sternson LA.
PMID: 16867804
J Pharm Biomed Anal. 1983;1(3):339-46. doi: 10.1016/0731-7085(83)80046-6.

The influence of electrolytes on the retention of organic cationic solutes in reversed-phase high-performance liquid chromatography (RP-HPLC) has been investigated. The effects of the nature and concentration of electrolytes and mobile phase pH on the retention of two model...

[Determination of distearyl dimethyl ammonium chloride in textiles by reversed-phase and normal-phase liquid chromatography-electrospray ionization tandem mass spectrometry].

Se pu = Chinese journal of chromatography

Ding Y, Shen X, Wu X, Wu L, Cao X.
PMID: 22032161
Se Pu. 2011 Jun;29(6):507-12. doi: 10.3724/sp.j.1123.2011.00507.

A method of reversed-phase (RP)/normal-phase (NP)-liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS) was developed for the determination of distearyl dimethyl ammonium chloride (DSDMAC) in textiles. The DSDMAC in textile was extracted by ultrasound-assisted extraction using methanol as extraction solvent under...

The purpose of this study was to investigate and compare the efficacy of various disinfectants on planktonic cells and biofilm cells of Listeria monocytogenes, Staphylococcus aureus and Escherichia coli. Numbers of viable biofilm cells decreased after treatment with all...

Transcriptome analysis of Listeria monocytogenes exposed to biocide stress reveals a multi-system response involving cell wall synthesis, sugar uptake, and motility.

Frontiers in microbiology

Casey A, Fox EM, Schmitz-Esser S, Coffey A, McAuliffe O, Jordan K.

Front Microbiol. 2014 Feb 28;5:68. doi: 10.3389/fmicb.2014.00068. eCollection 2014.

Listeria monocytogenes is a virulent food-borne pathogen most often associated with the consumption of "ready-to-eat" foods. The organism is a common contaminant of food processing plants where it may persist for extended periods of time. A commonly used approach...

Antimicrobial Approaches for Textiles: From Research to Market.

Materials (Basel, Switzerland)
