Detection of Vibrio penaeicida in kuruma prawn after transport
(Japanese Society of Fish Pathology, 1997)
In Japan, vibriosis caused by Vibrio penaeicida usually occurs in cultured kuruma prawn (Penaeus japonicus) during summer and fall. The causative bacterium can easily be detected from overtly diseased prawns, but from ...
Level and percentage recovery of resistance to oxytetracycline and oxolinic acid of bacteria from shrimp ponds
(Elsevier, 2002)
The bacterial level of the water, sediment and cultured shrimp (Penaeus monodon) from different ponds were determined using a general medium, a presumptive Vibrio medium and a presumptive Pseudomonas–Aeromonas medium. ...
Mortality in pond-cultured shrimp Penaeus monodon in the Philippines associated with Vibrio harveyi and white spot syndrome virus
(Japanese Society of Fish Pathology, 2003)
Heavy mortalities were observed among pond-cultured Penaeus monodon in the provinces of Bohol, Misamis Occidental, Lanao del Norte and Zamboanga del Sur, Philippines. Vibrio harveyi was isolated purely from the hepatopancreas ...
Bacterial diseases in shrimp (Penaeus monodon) culture in the Philippines
(Japanese Society of Fish Pathology, 1998)
The hatchery system for Penaeus monodon evolved from the Japanese community culture system to the modified Galveston method and this shift in culture technique triggered the outbreak of diseases due to opportunistic bacteria. ...
Prevalence of monodon baculovirus (MBV) in wild shrimp Penaeus monodon in the Philippines
(Elsevier, 2008)
Prevalence of monodon baculovirus (MBV) was determined using polymerase chain reaction (PCR) on deoxyribonucleic acid (DNA) extracts from the hepatopancreas of the wild black tiger shrimp, Penaeus monodon collected from 7 ...
Local Vibrio isolates exhibit molecular characteristics distinct from reference V. harveyi and V. campbellii strains
(University of the Philippines, 2005)
Six Vibrio isolates identified biochemically as Vibrio campbellii from Southeast Asian Fisheries Development Center (SEAFDEC) in Tigbauan, Iloilo, were characterized by 16 rDNA sequence, total protein profile, and DNA ...
Genetic diversity of wild and cultured black tiger shrimp (Penaeus monodon) in the Philippines using microsatellites
(Elsevier, 2001)
Six microsatellites were used to study (1) the genetic diversity of wild <i>Penaeus monodon</i> shrimp from four geographic regions (Palawan, Quezon, Capiz and Negros Occidental-W) in the Philippines, and (2) its association ...
Distribution of nervous necrosis virus in orange-spotted grouper Epinephelus coioides with asymptomatic infection
(Japanese Society of Fish Pathology, 2007)
Distribution of nervous necrosis virus in asymptomatically infected orange-spotted grouper Epinephelus coioides was determined by PCR assay in this study. Fourteen different tissues and organs were collected from apparently ...
Microsatellite and mitochondrial haplotype diversity reveals population differentiation in the tiger shrimp (Penaeus monodon) in the Indo-Pacific region
(International Society for Animal Genetics, 2008)
The black tiger shrimp (Penaeus monodon) is an ecologically and economically important penaeid species and is widely distributed in the Indo-Pacific region. Here we investigated the genetic diversity of P. monodon (n = ...
In vitro and in vivo evaluation of the efficacies of commercial probiotics and disinfectant against acute hepatopancreatic necrosis disease and luminescent vibriosis in Litopenaeus vannamei
(Elsevier, 2024-05)
The bioactivities of two commercially available probiotics and one chemical disinfectant were tested against strains of Vibrio parahaemolyticus (VP<sub>AHPND</sub>) and V. harveyi. This study aimed to determine shrimp pathogenic Vibrios' in vitro and in vivo sensitivities to commercial probiotics and a chemical disinfectant. The probiotics and disinfectant were tested first in vitro, followed by the in vivo trials. Results showed that upon administration of probiotics either through diet or adding into the tank water, the survivability of shrimp was increased during challenge with VP<sub>AHPND</sub> and V. harveyi. Also, the disinfectant was tested against the same pathogens and showed positive bactericidal effects at 2500 ppm and 5000 ppm. The present findings suggest that adding probiotics to the rearing water or the shrimp feeds effectively prevents infection by lowering the load of pathogenic bacteria. In comparison, the effectiveness of the disinfectant (PUR) depends on its appropriate concentration and timing of application. It is not only limited to rearing water but is also applicable for decontaminating pond liners, tanks, and other paraphernalia....
