Killing of xenogenous and virally infected homogenous target cells by shrimp lymphocyte-like haemocytes.

Haemocytes play a crucial role in the invertebrate's immune system. In our lab, five subpopulations of shrimp haemocytes were identified in the past: hyalinocytes, granulocytes, semi-granulocytes and two subpopulations of non-phagocytic cells. In the latter two subpopulations, their characteristics such as having small cytoplasmic rims and not adhering to plastic cell-culture plates are very similar to those of mammalian lymphocytes.

Shrimp (Penaeus vannamei) survive white spot syndrome virus infection by behavioral fever.

Both endotherms and ectotherms may raise their body temperature to limit pathogen infection. Endotherms do this by increasing their basal metabolism; this is called 'fever'. Ectotherms do this by migrating to warmer places; this is called 'behavioral fever'.

Upregulation of torso-like protein (perforin) and granzymes B and G in non-adherent, lymphocyte-like haemocytes during a WSSV infection in shrimp.

Invertebrates only have an innate immunity in which haemocytes play an important role. In our lab, 5 subpopulations of haemocytes were identified in the past by an iodixanol density gradient: hyalinocytes, granulocytes, semi-granulocytes and two subpopulations of non-phagocytic cells. For the two latter subpopulations, the haemocytes have small cytoplasm rims, do not adhere to the bottom of plastic cell-culture grade wells and present folds in the nucleus.

A study on the oral and cloacal bacterial flora of Mugger crocodiles () in the Negour protected area, Iran.

Mugger crocodile is the only crocodile existing in Iran. The present study was aimed to investigate the bacterial flora in oral and cloacal cavities of wild Mugger crocodiles in Negour protected area, Iran. The isolation and molecular characterization of oral and cloacal bacterial flora were performed in 22 Mugger crocodiles captured in Negour protected area, Iran.

Combined effects of exposure to sub-lethal concentration of the insecticide chlorpyrifos and the herbicide glyphosate on the biochemical changes in the freshwater crayfish Pontastacus leptodactylus.

Glyphosate is an herbicide that inhibits the growth of weed plants, while chlorpyrifos is an insecticide commonly applied to control the pests' population. This study aimed to investigate the combined effects of chlorpyrifos and glyphosate on biochemical, immunological parameters, and oxidative stress biomarkers in freshwater crayfish Pontastacus leptodactylus for 21 days. The experimental design of this study was factorial (3 × 3), including 0.
