چکیده
MIC, minimum inhibitory concentration; TMP/SMX, trimethoprim/ sulfamethoxazole. Vibrio harveyi (synonym V. carchariae), is a motile Gram-negative rod which is facultatively anaerobic, halophilic and bioluminescent [1]. It is found free-swimming in tropical marine waters and commensally in the gut microflora of marine animals. It is a pathogen of marine animals [2,3], although it has been considered nonpathogenic to humans [4]. To our knowledge, only three previous cases of human infection caused by this bacterium have been reported. The first occurred after a shark bite [5], the second was an episode of catheter-related bacteraemia in a British oncologic paediatric patient with a central line after his return from holiday in Perpignan, France, where he had swum in the sea [6], and the third was a wound mixed infection of Photobacterium damselae and Vibrio harveyi in a German man who, on a trip to west Australia, had experienced a laceration injury to the right tibia after falling from a catamaran [7]. Our case occurred in a 49-year-old man referred from the emergency room for cleaning and debridement of an infected wound in the right pretibial region. One week ago, during a trip to the Dominican Republic, he had experienced trauma from striking a bus step. The wound was sutured, and he was given antibiotic treatment with cefadroxil. He subsequently swam in the sea without protecting the bandage from the seawater. At admission, the patient was afebrile and presented a wound on the front and another on the inside of the distal third of the right leg. He was receiving treatment for ankylosing spondylitis with steroids, infliximab and methotrexate. A wound swab was submitted for microbiologic examination. After overnight incubation, a Gram-negative rod, oxidase positive, was isolated and sent for routine identification and susceptibility testing (MicroScan; Beckman Coulter). The next day, no growth was observed, and tests were repeated, adding NaCl up to a 1% final concentration. MicroScan identified the isolate as Vibrio

Marine microorganisms are uncommon etiologies of skin and skin structure infections, that is, wound infections. We report a case of severe wound infection, caused by the marine Photobacterium damselae (Vibrionaceae), in a 64-year-old male patient, returning from Australia. The isolate tested positive for pPHDD1, a plasmid conferring high-level virulence. Furthermore, the wound was coinfected wi...

Isolation of autochthonous bacteria from marine sources as a potential probiont in biocontroling against pathogenic Vibrio species in the shrimp culture industry was the aim of current research. A total of 198 bacterial strains were isolated from pond water, sediment, hepatopancreas and gut samples of shrimps after culturing the samples on Tryptic Soy Agar and incubated at 30 °C for 24-48 h.

متن کاملVibrio species isolated from diseased farmed sole, Solea senegalensis (Kaup), and evaluation of the potential virulence role of their extracellular products.
Bacteria isolated from an outbreak with moderate mortalities in farmed sole, Solea senegalensis (Kaup), in the south of Spain were identified as Vibrio harveyi and V. parahaemolyticus. Only bacterial strains showing swarming were virulent in sole and caused mortalities in experimentally inoculated fish. However, the signs of the disease were only reproduced with V. harveyi. The intramuscular in...

In this research Vibrio harveyi strains were isolated and identified from hepatopancreas of Litopenaeus vannamei from Tiab region, Hormozgan province. Shrimps samples were collected from five different ponds in northern and southern Tiab shrimp culture sites. Isolation phase was performed by dilution and inoculation of hepatopancreas samples on thiosulfate citrate bile salts sucrose agar medium...
