Abstract:

Certain parasites can cause severe diseases in shrimp. Among these, protozoa are very important. The objective of our study was to describe the signs, prevalence, and intensity of hemocytosis, a new disease in shrimp, Fenneropenaeus indicus. The experimental design included three groups, one treatment as infected shrimp or group B and 2 controls with non-infected but exposure to White Spot Syndrom Virus (WSSV) shrimp as group A and non-infected non- exposure to WSSV shrimp as group C in triplicate. The results revealed that Hemocytosis associated with a decrease in hyalinocytes and large-granulocytes (less than 8%) and a considerable increase in semi-granulocytes in group A and B in contrast to group C that Hyalinocyte increased. This infection made the shrimp susceptible to WSSV disease. It is believed that Hemocytosis causes a condition which can result in a rapid mortality among susceptible species, F. indicus when exposure to WSSV is occurred.

Selected morpho-chemical features of hemocytes in farmed shrimp, Fenneropenaeus indicus in Iran

The aim of the present study was to determine various types of hemocytes, total and differential hemocyte count and to show some indices of phagocytosis, including percent phagocytosis and phagocytic index in Indian white shrimp, Fenneropenaeus indicus in Iranian shrimp farms. The hemolymph was extracted from the shrimps and mixed with anticoagulant. It then stained and Yeast was added as forei...

Molecular characterization of a crustin-like, putative antimicrobial peptide, Fi-crustin, from the Indian white shrimp, Fenneropenaeus indicus.

Antimicrobial peptides are important innate immune defense, especially in those animals which lack adaptive immunity [1e8]. Due to their small size, amphipathic structure and cationic character they can rapidly diffuse to the point of infection [9], a mechanism that presumably makes it easier to circumvent microbial resistance against the peptides [10]. Besides providing an immediate and broad-...

Introduce of Pseudomonas psychrophila, as a new Pathogen Causing Disease in Cultured Rainbow trout (Oncorhynchus mykiss)

This is the first report on the world that Pseudomonas psychrophila is a new etiological agent of disease in fish. A disease case occurred during the fall of 2017 in a rainbow trout farm in the north of Iran (Guilan province). Anorexia, lethargy and mortalities of 10% fish per week were observed in rainbow trout Oncorhynchus mykiss weighting 45-107g in three fresh water ponds of a farm on the n...

Antimicrobial and Antifungal Effects of Acid and Water-Soluble Chitosan Extracted from Indian Shrimp (Fenneropenaeus indicus) Shell

Background & Objective : Currently, efforts are underway to seek new and effective antimicrobial agents, and marine resources are potent candidates for this aim. The following study was conducted to investigate the efficacy of water-soluble and acid-soluble chitosan against some pathogenic organisms.   Materials & Method s: Inhibition zone of different concentrations (5, 7.5, and 10 mg/ml) of a...
