Inactivation of Escherichia coli O157:H7, Salmonella Typhimurium and Listeria monocytogenes by underwater shock waves

Infected Urinary Stones, Endotoxins and Urosepsis

“…Bacteria from different genera and species have different resistances to physical, chemical and environmental factors; such variations in bacteria may determine the degree of susceptibility to shock waves. For instance, we have previously found that shock wave-induced cavitation contributes to L. monocytogenes, S. typhimurium and E. coli O157:H7 inactivation; however, L. monocytogenes was more sensitive to shock waves than E. coli O157:H7 (Alvarez et al, 2004). Kerfoot and colleagues (1992) found no effect of shock wave application on S. aureus; however von Eiff et al (2000) reported inactivation of a different strain of the same bacteria.…”

Inactivation kinetics of Salmonella spp. under thermal and emerging treatments: A review

“…For example, the use of shock waves against Salmonella Typhimurium achieved a 1.7 log reduction after 350 shock waves were applied. Light, electric discharge and cavitation are some of the main reasons for bacteria inactivation when using this technology (Alvarez, Loske, Castaño-Tostado, & Prieto, 2004).…”

Study on development of vessel for shock pressure treatment for food

“…(1) (2) where i and t superscripts represent the incident wave and the transmitted wave, respectively. ρ A and ρ B show the initial density of medium A and medium B, respectively.…”

“…15, and the hardness of apples is shown in Table 5. The hardness of apples was measured at the center of (3), near of the peel (1), and the in the middle of 3 and 1 (2). An apple does come apart by the shock wave, and almost retains its initial form.…”
