Effect of Schizothrix calcicola on white shrimp Litopenaeus vannamei (Penaeus vannamei) postlarvae
Aquaculture, 2003The noxious effect of Schizothrix calcicola strain UTEX B-1936 to white shrimp Litopenaeus vannamei (Penaeus vannamei) postlarvae is reported. The larvae exposed to this cyanobacterium during a 15-day long experiment grew smaller and weighed less (R 2 =0.6704) than unexposed organisms (R 2 =0.9049).

Journal of Invertebrate Pathology
Enterocytozoon hepatopenaei (EHP) is a significant pathogen affecting penaeid shrimp, particularly farmed whiteleg shrimp Penaeus vannamei, causing hepatopancreatic microsporidiosis (HPM). Although initially reported in tiger shrimp P. monodon, limited data exists on its current impact and pathogenic potential of EHP infection in tiger shrimp due to ...

Histopathology of aflatoxicosis in the marine shrimp Penaeus stylirostris and P. vannamei
Journal of Invertebrate Pathology, 1982Abstract The acute and subacute toxicity of aflatoxin B1 to the marine shrimp Penaeus stylirostris and P. vannamei (Order: Decapoda, Class: Crustacea) was investigated. Experimental shrimp were exposed to a range of concentrations of the toxin directly by intramascular injection (from 2 to 160 μg aflatoxin B1/g body weight), or by multiple per os ...

Penaeus vannamei protease activating mechanism of sulfhydryl reducing compounds
International Journal of Biological Macromolecules, 2018For the very first time, protease enzyme from Penaeus vannamei was investigated for its activation with thiol reductant compounds. The mechanism by which sulfhydryl reductant compounds enhances the activity of P. vannamei protease still remains unclear. In this study, it was discovered that thiol-reactive compounds increase P.

Metabolic responses of the white shrimp, Penaeus vannamei, to ambient ammonia
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2000Juvenile shrimp were individually exposed during 24 h to 0.007 (control), 0.36, 1.07, and 2.14 mmol/l total ammonia-N at 28 degrees C and 39 ppt salinity. After 22 h of ammonia-N exposure, oxygen consumption was measured for 2 h, and then hemolymph, hepatopancreas, and muscle tissues were sampled.

Characteristics and functional analysis of a novel mannose receptor in Penaeus vannamei
Fish & Shellfish ImmunologyThe mannose receptor (MR) plays a key role in the innate immune system as a pattern recognition receptor. Here, a novel type of mannose receptor, named PvMR2, was identified from Penaeus vannamei (P. vannamei). The PvMR2 coding sequence (CDS) obtained was 988 base pairs in length, encoding a protein consisting of 328 amino acids.

[Effects of probiotics on Penaeus vannamei pond sediments].
Ying yong sheng tai xue bao = The journal of applied ecology, 2007This paper studied the effects of probiotics on the sediment of Penaeus vannamei pond during 117 days of culture period. The results showed that probiotics application significantly decreased the concentrations of total nitrogen, total phosphorous, and sulfide in sediment, but no significant difference was observed in total plate count (TPC) of ...

The effects of the sanhuanglianqiao mixture on Vibrio parahaemolyticus infection in Penaeus vannamei
Microbial PathogenesisThe Sanhuanglianqiao mixture (SHLQ) was prepared from a certain proportion of Scutellaria baicalensis Georgi, Forsythia suspensa, and Rheum palmatum L and obtained by water extraction and alcohol precipitation. This study explored the effects of SHLQ on Penaeus vannamei and its protective role against Vibrio parahaemolyticus (V.
