The use of antioxidants and antibacterial compounds obtained from natural sources is important for human animal health, as well controlling diseases. aim this study was to evaluates the antioxidant potentials effects water extracts C. sativa, U. dioica, A. deliciosa aurantium against selected Gram-negative (Vibrio harveyi, Vibrio vulnificus, anguillarum, rotiferianus, campbellii, ponticus Aerom...

Vibrio harveyi is an important marine pathogen that is responsible for vibriosis outbreaks in cultured fish and invertebrates worldwide. Here, we announce the draft genome sequences of V. harveyi strains VH2 and VH5, isolated from farmed juvenile Seriola dumerili during outbreaks of vibriosis in Crete, Greece.

Loss due to diseases is a major problem in both shrimp farm and hatcheries and to control diseases, a number of antibiotics, sanitisers and chemicals are being used. This results in adverse environmental effects, emergence of antibiotic resistance and persistence of chemical residues in animal tissues. Considering the negative impact of antibiotics and other chemotherapeutants, biological contr...

Vibrio harveyi is a Gram-negative marine γ-proteobacterium that is known to be a formidable pathogen of aquatic animals and is a model organism for the study of bacterial bioluminescence and quorum sensing. In this report, we describe the complete genome sequence of the most studied strain of this species: V. harveyi ATCC 33843 (392 [MAV]).

Eight Vibrio isolates originating from the marine corals Mussismilia hispida and Phyllogorgia dilatata and the zoanthids Palythoa caribaeorum and Palythoa variabilis in Brazil and the Pacific white shrimp (Litopenaeus vannamei) in Ecuador were studied by means of a polyphasic approach. The novel isolates formed a tight monophyletic group in the genus Vibrio and were closely related to species o...

The “greenwater culture” of the tiger shrimp, Penaeus monodon, is an innovative culture technique for the grow-out rearing of shrimps. This culture method involves the use of rearing water of tilapia for the rearing of tiger shrimp in grow-out ponds and or the polyculture of shrimp with tilapia. This culture technique was reported to prevent disease outbreaks attributed to luminescent Vibrio. T...

The Outer Membrane Protein (OMP) of Vibrio alginolyticus cell wall was administered intramuscularly (IM) to the tiger shrimp (Penaeus monodon Fab.) at 10, 20, 30 μg/kg bw. After 14 days infection, the tiger shrimps were challenged with 10(7) bacterial density of Vibrio harveyi for 24 hours. The total haemocyte count (THC), differential haemocyte count (DHC) and amount of total protein plasma (T...

The aim of this research was to study the occurrence of Vibrio spp., Aeromonas hydrophila, Escherichia coli and Campylobacter spp. in crayfish from Azerbaijan Province using culture method and PCR assay. A total of 55 isolates were collected from 97 studied samples. Vibrio spp., A. hydrophila, E. coli and Campylobacter spp. were detected in 26 samples (26.8%), 12 samples (12.3%), 15 samples (15...
