C-type lectins are animal proteins that contain at least one carbohydrate recognition domain (CRD) capable of mediating sugar and calcium binding. Carbohydrate recognition is directly required for some biological functions, including the innate immune response. We cloned two novel C-type lectin (CTL) precursors from the commercial marine shrimp Litopenaeus vannamei. The cloned cDNAs encompass O...

A portion of the genome of yellow head virus (YHV) of penaeid shrimp was cloned and the cDNA fragment (1161 bp) was designated clone 3-27. The fragment was labeled with digoxigenin and hybridized in situ to tissue sections of YHV-infected Penaeus vannamei. Positively reacting tissues included those of the lymphoid organ, cuticular epithelium, and gills. In addition, connective tissue of hepatop...

Shrimp aquaculture is under pressure to increase its production meet the growing demand for food from a population. In Philippines, has experienced shift milkfish prawn, with attractive marketable price. This intensification led negative and positive impacts, which have raised range of environmental socioeconomic problems. paper reviews challenges that shrimp industry faces using Preferred Repo...
