Bleb Formation on the Cell Envelope of Osmotic Shocked Cells of Vibrio parahaemolyticus.

Abstract

Vibrio parahaemolyticuscells are known to lyse in distilled water on account of their osmotic fragility. When V. parahaemolyticus cells were subjected to osmotic shock, blebs were formed on cell envelopes, mainly at the septa of dividing cells and polar regions. Some of the blebs appeared to be detached from the cell surface to form vesicles. Our results indicate that surface blebs and vesicles formed by osmotic shock mainly involve the outer membrane . Although the cytoplasmic membrane itself is not released, its permeability barrier is disrupted.

Kinetics of the Inactivation of <i>Vibrio parahaemolyticus</i> in Weakly Acidic Sodium Chlorite Solution

“…Vibrio parahaemolyticus has been recognized as a cause of seafood-born gastroenteritis in Asia and other countries Katsui et al, 1999;Wong et al, 2001 . Food poisoning caused by V. parahaemolyticus has been occurring all over the world, especially since 1996 Fournier and Ogata, 2005 .…”

Inactivation of <i>Vibrio parahaemolyticus</i> Unattached and Attached to a Solid Surface in pH-Controlled Sodium Hypochlorite Solutions

“…Vibrio parahaemolyticus has been known to be one of the major food-poisoning bacteria in Asia Katsui et al, 1999;Urano et al, 2006;Wong et al, 2002 . Since 1996, the increase in the incidence of V. parahaemolyticus infections has been reported worldwide, e.g., in North America, India, and Europe Fournier and Ogata, 2005 .…”
