Effect of dietary formic acid and astaxanthin on the survival and growth of Pacific white shrimp (Litopenaeus vannamei) and their resistance to Vibrio parahaemolyticus
A 90-day feeding trial was conducted to evaluate the effects of formic acid (FA) and astaxanthin (AX) on growth, survival, immune parameters, and tolerance to Vibrio infection in Pacific white shrimp. The study was divided into two experiments. In experiment 1, postlarvae-12 were randomly distributed into six groups and then fed four times daily with six experimental diets contained 0.3 % FA, 0...
متن کاملEvaluation of antibacterial activity of Pseudomonas species isolated from Pacific white shrimp (Litopenaeus vannamei Boone, 1931) against pathogenic Vibrio spp.
In this research antibacterial activity of Pseudomonas isolates derived from hepatopancreas of Litopenaeus vannamei were evaluated against pathogenic Vibrio spp. Shrimp samples collected from 9 different ponds in Tiab region- Hormozgan province. Hepatopancreas samples of collected shrimps were inoculated in three different isolation media. Pseudomonas Isolation Agar medium revealed highest yiel...
متن کاملChemical Composition and Antimicrobial Effect of Five Essential Oils on Pathogenic and Non-Pathogenic Vibrio parahaemolyticus
Background and Objectives: Vibrio parahaemolyticus is the causative agent of gastroenteritis due to consumption of contaminated seafood. The aim of the present study was to determine the chemical composition of Essential Oils (EOs) of five plants (Artemisia absinthium, Zataria multiflora Boiss., Pulicaria gnaphalodes, Trachyspermum ammi and Cuminum cyminum) and to evaluate their antimicrobial a...
متن کاملShrimp AHPND-causing plasmids encoding the PirAB toxins as mediated by pirAB-Tn903 are prevalent in various Vibrio species
Acute hepatopancreatic necrosis disease (AHPND) is a newly emerging shrimp disease caused by pirAB toxins encoded by a plasmid found in Vibrio parahaemolyticus. The pirAB toxins are the homologs of the Photorhabdus insect-related (Pir) toxins. Here, we report the complete sequences of the AHPND-causing plasmid isolated from V. owensii, as well as those of its 11 siblings (pVH family). In additi...
متن کاملEffects of dietary astaxanthin on the immune response, resistance to white spot syndrome virus and transcription of antioxidant enzyme genes in Pacific white shrimp Litopenaeus vannamei
Three different experiments were conducted to study the effect of dietary astaxanthin on the immune response, resistance to white spot syndrome virus (WSSV) and transcription of antioxidant enzyme genes in Pacific white shrimp Litopenaeus vannamei. Each experiment included one triplicate treatment group (fed with 80 mg/kg astaxanthin supplemented diet) and one triplicate control group (fed with...
