The aquatic ecosystem is the natural habitat of microorganisms including Vibrio and Aeromonas genus which are pathogenic to human and animals. In the present investigation the frequency of these bacteria and the enzymatic characteristics of 34 Vibrio alginolyticus strains isolated from bivalves harvested in Venice Lagoon (Italy) and Guanabara Bay (Brazil) were carried out from November 2003 to ...
A Vibrio strain isolated from Alaskan oysters and classified by its biochemical characteristics as Vibrio alginolyticus possessed a thermostable direct hemolysin-related hemolysin (trh) gene previously reported only in Vibrio parahaemolyticus. This trh-like gene was cloned and sequenced and was 98% identical to the trh2 gene of V. parahaemolyticus. This gene seems to be functional since it was ...
Vibrio alginolyticus is one of the most common pathogenic marine Vibrio species, and has been found to cause serious seafood-poisoning or fatal extra-intestinal infections in humans, such as necrotizing soft-tissue infections, bacteremia, septic shock, and multiple organ failures. Delayed accurate diagnosis and treatment of most Vibrio infections usually result to high mortality rates. The obje...
Probiotic effect of Lactobacillus acidophilus against vibriosis in juvenile shrimp (Penaeus monodon)
The application of effective probiotics in shrimp aquaculture is an excellent alternative for chemicals and antibiotics to prevent disease control. This study was carried out to evaluate the probiotic potential of Lactobacillus acidophilus 04 (home made curd isolate) on pathogenic Vibrio in shrimp Penaeus monodon juveniles. L. acidophilus showed antibacterial activity against Vibrio parahaemoly...
In this study we investigated the phenotypic slime production of Vibrio alginolyticus and Vibrio parahaemolyticus strains, food-borne pathogens, using a Congo red agar plate assay. Furthermore, we studied their ability to adhere to abiotic surfaces and Vero cells line. Our results showed that only V. alginolyticus ATCC 17749 was a slime-producer developing almost black colonies on Congo red aga...
Vibrio alginolyticus has two types of flagella (polar and lateral) in one cell. We isolated mutants with only a polar flagellum (Pof+ Laf-) or only lateral flagella (Pof- Laf+). Using these mutants, we demonstrated that the energy sources of the lateral and polar flagellar motors in V. alginolyticus are H+ and Na+ motive forces, respectively, as in the related species V. parahaemolyticus.
Vibrio alginolyticus is a facultative anaerobic gram-negative bacillus found in normal marine flora. Ocular infections induced by V. alginolyticus are extremely rare. We report a case of endophthalmitis caused by V. alginolyticus to draw attention to V. alginolyticus infections following ocular injuries.
ویبریو آلجینولیتیکوس (vibrio alginolyticus) یکی از باکتری های گرم منفی بیماری زا و نمک دوست است که به خانواده ویبریوناسه تعلق دارد. به طور طبیعی این باکتری در محیط های دریایی معتدل و دهانه رودخانه یافت می شود که عفونت های انسانی مختلف از جمله عفونت زخم و گوش را ایجاد می کند. بنابراین، مطالعه پیش روبه منظور جداسازی و شناسایی ویبریو آلجینولیتیکوس همزیست از اسفنج های خلیج فارس با استفاده از کیت ها...
Vibrio alginolyticus, Vibrio fluvialis, and Vibrio parahaemolyticus utilized heme and hemoglobin as iron sources and contained chromosomal DNA similar to several Vibrio cholerae heme iron utilization genes. A V. parahaemolyticus gene that performed the function of V. cholerae hutA was isolated. A portion of the tonB1 locus of V. parahaemolyticus was sequenced and found to encode proteins simila...
Draft Genome Sequences of Vibrio sp. Strains Isolated from Tetrodotoxin-Bearing Scavenging Gastropod
Vibrio sp. strains JCM 18905 and JCM 19053 were isolated from a tetrodotoxin (TTX)-bearing scavenging gastropod, and Vibrio sp. strain JCM 18904 was isolated from a sea cucumber. All these are closely related to Vibrio alginolyticus. Their comparative genome information is useful for studies of TTX production in bacteria.
