This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The channel catfish (Ictalurus punctatus) is susceptible to bacterial and viral infections acqired from its pond environment. The innate immune proteins mannose-binding lectin (MBL) and lysozyme were studied in two different groups of channel catfish aged 2, 4, 6, 9, and 12 months-old. The two groups were maintained at a mean temperature of 27 0C and were one-year apart in their bleedings. Dot-blot enzyme linked immunosorbent assay for MBL and turbidometry lysozyme quantitive assays were done to determine the two innate immune proteins. The greatest increases in mean MBL and mean lysozyme concentrations were seen at 4 months. Two month-old catfish were comparable with 12 month-old catfish in their concentrations of MBL and lysozyme (p
Book Synopsis Effects of Microcystin-LR on Channel Catfish (Ictalurus Punctatus) Susceptibility to Microbial Pathogens (Aeromonas Hydrophila and Edwardsiella Piscicida) by : Alison Marchant
Download or read book Effects of Microcystin-LR on Channel Catfish (Ictalurus Punctatus) Susceptibility to Microbial Pathogens (Aeromonas Hydrophila and Edwardsiella Piscicida) written by Alison Marchant and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microcystin-LR is a hepatotoxin produced by cyanobacteria. Aeromonas hydrophila and Edwardsiella piscicida infections are leading causes of losses in market-sized channel catfish (Ictalurus punctatus). These older fish should have natural immunity in place and a predisposing factor is likely a prerequisite for these disease outbreaks. While microcystin-LR rarely causes mortality in warm-water aquaculture, we believe it may be a predisposing factor that leads to bacterial disease outbreaks during the summer months due to its ability to damage the liver. Our study investigated microcystin-LR’s effects on channel catfish susceptibility to these pathogens. We found that a sublethal dose of microcystin-LR induced substantial damage to multiple immune organs. In our challenges with both the toxin and bacteria, we saw a significant increase in mortality of fish. Our findings suggest that microcystin-LR increases channel catfish susceptibility to Aeromonas hydrophila and Edwardsiella piscicida infections.
Book Synopsis Vaccination and Immune Response of Channel Catfish (Ictalurus Punctatus) Against Virulent Aeromonas Hydrophila by : Basant Mahmoud Ali Gomaa
Download or read book Vaccination and Immune Response of Channel Catfish (Ictalurus Punctatus) Against Virulent Aeromonas Hydrophila written by Basant Mahmoud Ali Gomaa and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Virulent Aeromonas hydrophila (vAh) is a causative agent of motile Aeromonas septicemia (MAS) in catfish. There are limitations in the current therapeutic and preventative strategies against vAh. The pathogenesis of MAS as well as the immune response of catfish to vAh infection are poorly understood. The aim of this study is to: 1) develop a dual live attenuated vaccine against MAS and enteric septicemia of catfish caused by Edwardsiella ictaluri; and 2) evaluate the vAh bacterial load and gene expression patterns in catfish tissues following vAh infection. Previously, six recombinant vAh proteins (outer membrane protein, TonB-dependent receptor, three fimbrial proteins, and an ATPase) were identified to have vaccine efficacy against MAS, and live attenuated E. ictaluri vaccine strain ESC-NDKL1 was identified as an effective vector for expressing vAh antigens. A total of 29 recombinant ESC-NDKL1 strains have been constructed with the integration of one, two, or three genes encoding vAh antigens into the ESC-NDKL1 chromosome. Vaccine efficacy of the constructed strains was evaluated in channel catfish fingerlings. Four recombinant ESC-NDKL1 strains expressing two vAh antigens (ESC-NDKL1::atpase::fimMrfG, ESC-NDKL1::fim::fimMrfG, ESC-NDKL1::tdr::fimMrfG, and ESC-NDKL1::fim::ompA) showed significant protection against MAS with relative percent of survival (RPS) values of 55.72%, 60.18%, 61.74%, and 54.81%. Four triple recombinant ESC-NDKL1 strains (ESC-NDKL1::fimMrfG::ompA::fimA, ESC-NDKL1::atpase::fimMrfG::ompA, ESC-NDKL1::fim::fimMrfG::ompA and ESC-NDKL1::atpase::tdr::fim) showed the best protection with RPS values of 77.93%, 63.18%, 67.74%, and 82.35%. To gain a better understanding of vAh pathogenesis, catfish fingerlings were intraperitoneally injected with vAh strain ML09-119. The anterior kidney, liver, and spleen were collected for determination of vAh distribution and expression of thirteen pro-inflammatory, innate, and adaptive immune-related genes using real-time PCR. Results revealed that vAh spread into catfish tissues within 2 hours and peaked at 12 hours post-infection. vAh infection initiated a strong inflammatory response in catfish tissues. Additionally, our research revealed that surviving catfish were able to develop a primary immune response and possibly generation of memory B cells against MAS. Such information will facilitate the development of vaccines and therapeutic drugs for preventing and treating MAS outbreaks in catfish aquaculture.

Available in PDF, EPUB and Kindle. Book excerpt: The time seems ripe for a critical compendium of that segment of the biological universe we call viruses. Virology, as a science, having passed only recently through its descriptive phase of naming and num bering, has probably reached that stage at which relatively few new-truly new-viruses will be discovered. Triggered by the intellectual probes and techniques of molecular biology, genetics, bio chemical cytology, and high resolution microscopy and spec troscopy, the field has experienced a genuine information explosion. Few serious attempts have been made to chronicle these events. This comprehensive series, which will comprise some 6000 pages in a total of about 18 volumes, represents a commitment by a large group of active investigators to analyze, digest, and expostulate on the great mass of data relating to viruses, much of which is now amorphous and disjointed, and scattered throughout a wide literature. In this way, we hope to place the entire field in perspective, and to develop an invalua ble reference and sourcebook for researchers and students at all levels. This series is designed as a continuum that can be entered anywhere, but which also provides a logical progression of developing facts and integrated concepts.

Book Synopsis Ecology of Larval Fishes in Lake Oahe, South Dakota by : William Roland Nelson
Download or read book Ecology of Larval Fishes in Lake Oahe, South Dakota written by William Roland Nelson and published by . This book was released on 1980 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The time and location of spawning, food and larvae, and habitats used as nursery areas by young-of-the-year fishes were studied from 1972 to 1975 in South Dakota waters of Lake Oahe, a main stem Missouri River reservoir. Sampling locations were in the tributary rivres -- the Grand Moreau, and Cheyenne -- and their embayments. Year-class strength of river-spawning species was strongly correlated with river flow rates during the spawning season. Success of reservoir-spawning species was primarily dependent on above-average water levels, which inundated terrestrial vegetation to provide a substrate for egg deposition and cover for larvae. Preserving adequate streamflow and enhancing reservoir shoreline areas by managing water levels, seeding vegetation, and eliminating grazing alongshore would probably ensure adequate reproduction of most areas.
Book Synopsis Food of Alewives, Yellow Perch, Spottail Shiners, Trout-perch, and Slimy and Fourhorn Sculpins in Southeastern Lake Michigan by : LaRue Wells
Download or read book Food of Alewives, Yellow Perch, Spottail Shiners, Trout-perch, and Slimy and Fourhorn Sculpins in Southeastern Lake Michigan written by LaRue Wells and published by . This book was released on 1980 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stomachs of 1,064 alewives, 1,103 yellow perch, 246 spottail shiners, 288 trout-perch, 454 slimy sculpins, and 562 fourhorn sculpins from Lake Michigan were examined for food contents. Fish were sampled primarily from March to November and nearly all were caught at the bottom in the southeastern part of the lake near Saugatuck, Michigan. Pontoporeia was the most commonly reprented food item in the stomach contents of the fish examined, with immature midges, Mysis (a type of freshwater shrimp), copepods, cladocerans, fingernail clams and crayfish also being represented. Different species consumed different proportions of foods. Zooplankton was the principle food of alewives and spottail shiners, but was also consumed in small quantities by yellow perch and trout perch. Mysis was important to fourhorn sculpins, in addition to Pontoporeia. Immature midges were a major portion of spottail shiners and trout perch, also being consumed by alewives. Fish were often the most important food of yellow perch in the largest size category. Crayfish were a sizable portion of the diet of yellow perch on rocky bottoms, but sparingly on smooth bottoms. Spottail shiners also ate substantial numbers of fingernail clams.
Book Synopsis Toxicity of Three Herbicides (butyl, Isooctyl, and Propylene Glycol Butyl Ether Esters of 2,4-D) to Cutthroat Trout and Lake Trout by : D. F. Woodward
Download or read book Toxicity of Three Herbicides (butyl, Isooctyl, and Propylene Glycol Butyl Ether Esters of 2,4-D) to Cutthroat Trout and Lake Trout written by D. F. Woodward and published by . This book was released on 1978 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two formulations of the herbicide 2,4-D (2,4-dichlorophenoxyacetic acid) - the butyl ester (BE) and the propylene glycol butyl ether ester (PGBEE) -- had 96-h LC50's to cutthroat trout and lake trout ranging from 490 to 1,200 microgram/liter in static tests. A third formulation -- the isooctyl ester (IE) -- was not toxic to cutthroat trout or lake trout at concentrations below 60.000 microgram/liter. The butyl ester (2,4-D BE) was slightly more toxic than 2,4-D PGBEE, and the toxicity of both esters increased as water temperature decreased.
Book Synopsis Changes in Distribution of Trout in Great Smoky Mountains National Park, 1900-1977 by : George Alan Kelly
Download or read book Changes in Distribution of Trout in Great Smoky Mountains National Park, 1900-1977 written by George Alan Kelly and published by . This book was released on 1980 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Significant changes have occurred in the distribution of trout in streams of Great Smoky Mountains National Park since 1900. By the mid-1970's the original range of the native brook trout had been reduced by about 70% and the species was relegated to suboptimal habitat in head water streams. Most of the stream sections lost by brook trout became the territory of the introduced rainbow trout, which in 1977 occupied about 80% of the Park waters. After 1950, brown trout introduced in State waters outside the Park established reproducing populations in some 50 miles of stream formerly occupied only by rainbow trout. If current trends continue, the recovery of brook trout in Park water may be difficult, if not impossible, and brown trout may occupy much of the territory now held by rainbow trout.
