Under starvation conditions in artificial seawater, cells of V vulnificus did not adjust their membrane fluidity to storage temperature within the investigated time frame. However, a significant switch (p<0.05) from C18:1m7c into С 18:1 обе by double bond relocation was observed. The relocation occurred faster at ambient temperatures compared to refrigerated temperatures. It is generally known that majority of V. vulnificus associated infections occur during summer hot months. Vibrio vulnificus ATCC 27562 was significantly less resistant to simulated gastric fluid (pH 4.0) after 7-day storage at 4 °С compared to the control, with D-values of 3.7 and 7.8 minutes, respectively. Therefore, higher sensitivity of the pathogen to the gastric fluid in winter harvested oysters may also impact the low number of outbreaks.
