Swollen hindgut syndrome (SHG) in hatchery-reared Penaeus monodon postlarvae
(Fish Health Section, Asian Fisheries Society, 2002)In the course of routine microscopic analysis of hatchery-reared Penaeus monodon postlarvae, several batches were found with hindgut abnormalities not previously described in shrimp postlarvae. The abnormality was named ... -
Studies on the efficacy of Sarafin® (sarafloxacin hydrochloride) on vibrios associated with vibriosis in black tiger shrimp (Penaeus monodon)
Pakingking, Rolando V., Jr.
; ; (Fish Health Section, Asian Fisheries Society, 2002)
In vitro activity of Sarafin® (sarafloxacin hydrochloride) was determined against 7 luminous Vibrio harveyi isolates and 3 non-luminous Vibrio species (V. parahaemolyticus, V. alginolyticus and Vibrio species) isolated ... -
Quorum sensing and its potential application to vibriosis
(Fish Health Section, Asian Fisheries Society, 2002)Quorum sensing is a gene regulatory mechanism by which certain pathogenic and symbiotic bacteria respond to population density and host association. By mediating the ability of bacteria such as Vibrio harveyi to infect ... -
Identification and characterization of Vibrio bacteria isolated from fish and shellfish in Vietnam
(Fish Health Section, Asian Fisheries Society, 2002)A taxonomic relationship of thirty one Vietnamese bacterial isolates from different fish and shellfish together with twenty two reference strains was investigated by Euclidean distance with unweighted average linkage ... -
Growth promotion and enhancement of vibriosis resistance in penaeid shrimp after oral administration of lactic acid bacteria and marine bacteria
(Fish Health Section, Asian Fisheries Society, 2002)Vibriosis is one of the most serious problems in the shrimp culture industry worldwide. Antibiotic treatment is becoming less and less effective, as new strains of pathogens evolve, which are resistant to commonly used ... -
Genetic evidence for a unique taxonomic position of white spot syndrome virus of shrimp: Genus Whispovirus
(Fish Health Section, Asian Fisheries Society, 2002)White spot syndrome virus (WSSV) is a relatively new agent causing a zoonotic disease in shrimp. Taxonomically this virus is presently an orphaned, floating virus species. WSSV has a unique virion morphology, genome ... -
Prevalence of yellow head virus in cultured black tiger shrimp (Penaeus monodon Fabricius) from selected shrimp farms in the Philippines
(Fish Health Section, Asian Fisheries Society, 2002)The prevalence and geographic distribution of Yellow head virus (YHV) in cultured Penaeus monodon in the Philippines was documented by Western blot assay. Fifty-three out of 219 samples (24.2%) were found to be positive ... -
Effects of Artemia enriched with L-ascorbyl dipotassium-2-sulfate dihydrate on stress tolerance and disease resistance of Penaeus monodon postlarvae
(Fish Health Section, Asian Fisheries Society, 2002)Penaeus monodon postlarvae (stage 10) were reared with Artemia nauplii enriched with 50,100 and 150 mg/l (ppm) of L-ascorbyl-dipotassium-2- sulfate dihydrate for 5 days. Postlarvae in the control group were given non-enriched ... -
Alkalinity control in ozonated shrimp pond water
(Fish Health Section, Asian Fisheries Society, 2002)The use of ozone for aquaculture has been shown to be effective, not only for disinfection of pathogenic bacteria and viruses, but also for removal of toxic ammonia, nitrite and hydrogen sulfide. However, ozonation of ... -
Evaluation of the susceptibility of the shrimp Litopenaeus vannamei to vibriosis when exposed to agriculture pesticides
(Fish Health Section, Asian Fisheries Society, 2002)Due to increasing stringency of environmental regulations, agricultural production systems have switched from persistent pesticides to products which degrade more rapidly. In spite of that, new pesticide products can affect ... -
Detection of shrimp viral pathogens with a simple dot-blot enzyme immunoassay protocol
(Fish Health Section, Asian Fisheries Society, 2002)Dot-blot nitrocellulose enzyme immunoassays (DB-NC-EIA) were developed for the detection of two shrimp viral pathogens, white-spot virus (WSV), and yellow-head virus (YHV). The assays utilized HRP-conjugated virus-specific ... -
Isolation of FV3-like iridovirus from a cutaneous ulceration disease of cultured frog, Rana tigrina Cantor, in Thailand
(Fish Health Section, Asian Fisheries Society, 2002)A new frog disease occurred in frog culture farms located in Central Thailand since early 1998. The disease affects 20-100% of the frog population in affected farms. Diseased adult frogs usually exhibit ulcerative lesions ... -
Isolation and characterization of an Achlya sp. associated with diseased soft-shelled turtle (Trionyx sinensis) from Hong Kong
(Fish Health Section, Asian Fisheries Society, 2002)In September 1996, a disease outbreak was reported in one turtle farm in the New Territories, Hong Kong. Soft-shelled turtle (Trionyx sinensis) cultured in tanks showed white spots on their body surface and carapace resulting ... -
Differentiation of crocodilian granulocytes using histochemical techniques
(Fish Health Section, Asian Fisheries Society, 2002)Blood smears from 54 crocodiles of three breeds (Crocodylus siamensis, C. porosus, and crossbred) were examined after Wright-Giemsa staining. Detection for alkaline phosphatase and peroxidase activities were performed. ... -
Bacterial diseases of cultured tiger frog (Rana tigerina)
(Fish Health Section, Asian Fisheries Society, 2002)Diseased cultured tiger frogs (Rana tigerina), from 173 farms throughout Thailand, were submitted for diagnosis at Aquatic Animal Health Research Institute from 1994-1998. Bacterial species were isolated from sick frogs ... -
Computer-based resources for aquatic animal health
(Fish Health Section, Asian Fisheries Society, 2002)A brief review of computer-based resources for aquatic animal health is presented, with emphasis on information sources likely to be of interest to scientists, diagnosticians, and university instructors working in the Asian ... -
Emerging shrimp diseases and innovations to prevent their spread
(Fish Health Section, Asian Fisheries Society, 2002)The number of diseases affecting cultivated penaeid shrimp has increased steadily with expansion and intensification of large-scale commercial cultivation. In the 1990s the most serious losses have occurred from the emergence ... -
Significant diseases of molluscs in the Asia-Pacific region
(Fish Health Section, Asian Fisheries Society, 2002)There have been relatively few studies on the diseases of molluscs in the Asian region, and those that have been carried out are often difficult to access. Therefore, our current knowledge of mollusc diseases in Asia is, ... -
Birnaviruses of potential new serogroups isolated from tropical fish
(Fish Health Section, Asian Fisheries Society, 2002)Over the last 10 years, viruses have been isolated from fish imported into Singapore and also from indigenous fish in Singapore. In 1993, the marble goby Oxyeleotris marmorata** underwent viral diagnostic investigation as ... -
