Floating marine debris and litter act as a vector transporting various species across long distances. The present study reports possible transoceanic rafting of a small colony of barnacles on an unopened plastic bottle of Chinese origin found washed ashore on the Ninety Mile Beach in Victoria, Australia. The crustaceans attached were identified to be the goose barnacle Lepas pectinata. Based on the number and size of the colony the marine pollutant was estimated to adrift for several months. We hypothesised the origin of the flotsam, especially the barnacles and how it made its way from the Pacific to be washed ashore in Australia. Furthermore, we identified two types of microbes, Vibrio alginolyticus and Vibrio parahaemolyticus, associated with the Lepas pectinata growing on the bottle. This study appears to be the first report of possible transoceanic rafting on unused plastic pollutants and highlights the potential environmental threats caused by plastic.

Pathogenic Vibrios

Pathogenic vibrios are important etiologic agents in tropical regions and have been frequently recovered from seafoods and aquacultured foods. In this study, commercially frozen seafoods including peeled shrimps and fish and shrimp dumplings were examined. Vibrio alginolyticus, Vibrio parahaemolyticus, Vibrio cholerae and Vibria fluvialis were recovered at 36.0%, 15.8%, 14.9% and 13.2%, respectively. A number of psychrotrophic vibrios were selected and their survival in tryptic soy broth (TSB) supplemented with 1% sodium chloride (NaCl) (TSBS medium) and shrimp homogenate at 4°C and −30°C were studied. Two psychrotrophic non-O1 V. cholerae (laboratory stocks no 128 and 129) survived well at these low temperatures. Counts decreased by about 1 log/ml in TSBS medium at 4°C for 6 days and 3 log/ml at −30°C for 3 days. Shrimp homogenate provided better protection than TSBS medium for psychrotrophic V. cholerae at −30°C. Survival of V. cholerae at low temperatures was further increased by the addition of 0.5% of heated pyrophosphate and metaphosphate, probably by decreasing the lethality of the cold injury to the cells. Measures should be taken to minimize the risk from pathogenic vibrios in frozen seafoods, especially if phosphates are used and psychrotrophic strains are present.

Vibrio alginolyticuswas originally classified as biotype 2 ofVibrio parahaemolyticus. Most clinical isolates are recovered from superficial wounds or the external ear infections.V. alginolyticusis acknowledged to be nearly nonpathogenic in humans. The reason for presence ofV. alginolyticus’s virulence is uncertain. We describe a chronic myringitis case in a 47-year-old female due toV. alginolyticus. According to her anamnesis, it was detected that she had sea bathing history in Mugla Coast in Turkey. Pure isolation ofV. alginolyticuswas obtained from external auditory canal’s culture. Investigation and antimicrobial susceptibility of the isolate were performed by the automatized BD Phoenix system and Kirby-Bauer disk diffusion method, respectively. The bacteria were sensitive to all antibiotics. This case was presented to pay attention toVibrio alginolyticusinfections.

Fatal Septicemia

A halophilic Vibrio species was isolated from blood cultures from a 59-year-old male with enteritis. The strain differed from Vibrio parahaemolyticus and Vibrio alginolyticus by its ability to ferment lactose, its production of beta-galactosidase, and its lower NaCl tolerance. A report of this infection and a description of the isolate is presented.
