Sažetak
Vibrio vulnificus belongs to the autochtonous halophilic bacteria flora of estuarine and coastal water, possibly existing as a symbiont of oysters. Vibrio vulnificusis a opportunistic lethal human pathogen capable of producing septicemia in susceptible persons. Disease is almost always associated with consumption of seafood, particularly raw oysters or with exposure of wounds to sea water. Distributions of this bacterium in environmental samples were obtained from multiple sites in the Split area. Samples were collected between December 1994 and December 1995. Enumerated Vibrio vulnificus populations from the surface water, oysters by indirect colony count on nonselective media, using a variety of media for recovery. Total aerobic, heterotrophic, culturable bacteria were enumerated by plate count on nonselective medium. The number of Vibrio vulnificus was determined on nonselective medium (LA) prepared with artificial sea water (ASW) and selective thiosulfate citrate bile salts agar (TCBS). Vibrio vulnificus was readily delectable in surface water samples and constituted a significant proportion of the total culturable heterothropic bacteria populations in samples collected during warmer months of the year. The heterothropic populations in sea water ranged from 2.0 x 102 do 1.6 x 105 organisms per ml of water. When detectable, the number of Vibrio vulnificus in surface water ranged from 2 x 101 do 0.5 x 102/ml and averaged between 0.5 and 4.8% of total bacteria population. As for the water samples, Vibrio vulnificus was not detected in oyster during the coldest months at temperatures of 17.5 C. At other times of the year, Vibrio vulnificus was present in oysters in numbers ranging from 4x101 do 3.8x102 cells per g of oysters. Rapid indetification of Vibrio vulnificus in seafood therefore is essential to reduce the potentially hazardous effects of widespread consumption of contaminated oysters.
