A comparison of strategies for the detection and recovery of Vibrio vulnificus from marine samples of the Western Mediterranean coast
1998
Summary We have compared the effectiveness of culture-based methods and a DNA-based method for the detection, of Vibrio vulnificus from seawater and three types of shellfish collected from the coastal waters of Valencia, Spain. For culture-based method, we used two selective media, thiosulphate-citrate-bile salts-sucrose (TCBS), and cellobiose-polymyxin B-colistin (CPC) agars with and without previous enrichment in alkaline-saline-peptone-water (APWS). Presumptive colonies were confirmed as V. vulnificus by the polymerase chain reaction (PCR) using previously described 23S rRNA V. vulficus -specific sequences as primers (Dvu 9V and Dvu 45R). Direct detection was accomplished by a nested-PCR…

Isolation of Gram-positive n-alkane degraders from a hydrocarbon-contaminated Mediterranean shoreline.
2007
Aims: To investigate the petroleum hydrocarbon (HC)-degrading potential of indigenous micro-organisms in a sandy Mediterranean coast, accidentally contaminated with petroleum-derived HCs. Methods and Results: Using culturable methods, a population of Gram-positive n-alkane degraders was detected in the contaminated soil. Five isolates, identified as one Nocardia, two Rhodococcus and two Gordonia strains, were able to degrade medium- and long-chain n-alkanes up to C36 as assessed by growth assays and gas chromatography-mass spectrometry analysis. Diverging alkane hydroxylase-encoding genes (alkB) were detected by PCR, using degenerated primers, in all the strains; multiple sequences were obt…

Abstract By 2030, the annual number of combined total hip and knee arthroplasty is estimated to reach 3.5 to 4 million in the US alone. In the context of a constant increase of the number of primary and revision total hip and knee arthroplasty, an increased risk of complication is expected. Prosthetic joint infections (PJIs) represent major cause of healthcare expenditure and morbidity. PJI still remain the most common and feared arthroplasty complication. A rapid and correct diagnosis of infection is decisive for a correct therapeutical management. In this setting, the Academic Emergency Hospital Sibiu adopted and implemented, with the beginning of September 2016, a new strategy for the di…
