Studies on the chemical control of luminous bacteria Vibrio harveyi and V. splendidus isolated from diseased Penaeus monodon larvae and rearing water
(Inter Research, 1990)
The minimum inhibitory concentrations (MICs) and minimum bactericidal concentrations (MBCs) of 24 drugs for luminous bacteria Vibrio harveyi and V. splendidus were determined. Only chloramphenicol, sodium nifurstyrenate ...

Luminescent vibrios associated with mortality in pond-cultured shrimp penaeus monodon in the Philippines: Species composition
(Japanese Society of Fish Pathology, 2001)
Heavy mortalities due to luminescent vibriosis have been observed among pond-cultured Penaeus monodon shrimp in the Philippines. The species composition of luminescent Vibrio associated with mortalities was determined. A ...

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. ...

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 ...

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....
