An important issue that has not been investigated is whether the multiresistant Salmonella strains are more virulent than their susceptible counterparts. Salmonella isolates collected from clinical human ( n = 888) and porcine ( n = 2,120) cases at the same time period and geographic location were investigated. Antimicrobial susceptibility, PCR analysis for the spvA virulence gene, and pulsed-field gel electrophoresis (PFGE) genotyping were done. Carriage of spvA was associated with multidrug-resistant (MDR) type ACSSuT strains (odds ratio, 7.1; P < 0.05), a type often implicated in bacteremic human cases. PFGE revealed that clinical isolates from pigs were more clonally related to those of human origin than the nonclinical porcine isolates. The findings suggest that MDR strains that also carry specific virulence factors are more likely to be of clinical significance. }, number={3}, journal={JOURNAL OF CLINICAL MICROBIOLOGY}, author={Gebreyes, Wondwossen A. and Thakur, Siddhartha and Dorr, Paul and Tadesse, Daniel A. and Post, Karen and Wolf, Leslie}, year={2009}, month={Mar}, pages={777–780} } @article{sperry_kathariou_edwards_wolf_2008, title={Multiple-locus variable-number tandem-repeat analysis as a tool for subtyping Listeria monocytogenes strains}, volume={46}, ISSN={["1098-660X"]}, DOI={10.1128/JCM.02207-07}, abstractNote={ABSTRACT}, number={4}, journal={JOURNAL OF CLINICAL MICROBIOLOGY}, author={Sperry, Katharine E.

This response often depends on the activity of cytosolic phospholipase A2 (cPLA2), which catalyzes the release of arachidonic acid from the sn-2 position of membrane phospholipids. In this study, we investigate the ability of arachidonic acid itself to cause cell death. We show that in assays with 10% fetal bovine serum (FBS) arachidonic acid will not kill, nor does act synergistically with TNF. In contrast, by lowering the concentration of FBS to 2%, it is possible to use arachidonic acid to induce cell death. Arachidonic acid-induced cell death was judged to be apoptotic based on morphology and the cleavage of poly(ADP)ribose polymerase. Arachidonic acid was able to kill all cell lines tested including two human melanoma-derived cell lines, and susceptibility to arachidonic acid was not influenced by adenovirus gene products that control susceptibility to TNF. Finally, we show that arachidonic acid is unique among 20 carbon fatty acids for its ability to induce apoptosis and that several other unsaturated, but not saturated fatty acids can also induce apoptosis.}, number={3}, journal={Cell Biochemistry and Biophysics}, author={Wolf, L.
