Changes in haemolymph parameters and insect ability to respond to immune challenge during overwintering

open access: yesEcology and Evolution, 2021
Overwintering is a challenging period in the life of temperate insects. A limited energy budget characteristic of this period can result in reduced investment in immune system.

Exposure to Polymethylmethacrylate Microplastics Induces a Particle Size-Dependent Immune Response in Mediterranean Mussel Mytilus galloprovincialis

open access: yesFishes, 2022
The widespread occurrence of plastic has become a significant problem in the natural environment and may give rise to a range of deleterious impacts in biota, particularly where plastic particles overlap in size with that of the particles that are ...

Influence of Trichobilharzia regenti (Digenea: Schistosomatidae) on the defence activity of Radix lagotis (Lymnaeidae) Haemocytes. [PDF]

open access: yesPLoS ONE, 2014
Radix lagotis is an intermediate snail host of the nasal bird schistosome Trichobilharzia regenti. Changes in defence responses in infected snails that might be related to host-parasite compatibility are not known.

Short-Term Exposure of Mytilus coruscus to Decreased pH and Salinity Change Impacts Immune Parameters of Their Haemocytes

open access: yesFrontiers in Physiology, 2018
With the release of large amounts of CO2, ocean acidification is intensifying and affecting aquatic organisms. In addition, salinity also plays an important role for marine organisms and fluctuates greatly in estuarine and coastal ecosystem, where ocean ...

EFFECT OF FOLIC ACID ON THE HAEMOGRAM and SILK PRODUCTIVITY OF MULBERRY SILKWORM Bombyx mori L: (LEPIDOPTERA- BOMBYCIDAE) [PDF]

open access: yesJournal of Plant Protection and Pathology, 2007
The present investigation reports the effect of folic acid as supplemented feed on haemogram and some biological parameters of Bombyx mori L. All the tested concentrations of  folic acid  especially 10mg/100ml significantly increased the weight of larvae

A haemocyte tropism for an arbovirus

open access: yesJournal of General Virology, 2009
Horizontally transmitted mosquito-borne viruses enter the midgut with a blood meal then disseminate to infect the salivary glands. En route to the salivary glands, these viruses encounter the plasma (haemolymph) and blood cells (haemocytes). Haemocytes respond to a variety of micro-organisms, but their role in virus replication and dissemination has ...

Efficacy of vaccine from whole killed Vibrio alginolyticus cells on the immune response of white shrimp (Litopenaeus vannamei) [PDF]

open access: yesIraqi Journal of Veterinary Sciences
Vibrio alginolyticus causes high mortality in white shrimp, leading to significant worldwide losses to the aquaculture industries. Vaccine development has become a priority to prevent the spread of disease by activating the immune responses of aquatic ...

Cellular immune response of the Asian corn borer, Ostrinia furnacalis (Lepidoptera: Pyralidae), to infection by the entomopathogenic fungus, Beauveria bassiana

open access: yesEuropean Journal of Entomology, 2016
The term cellular immune response refers to haemocyte-mediated responses, including phagocytosis, nodulation, and encapsulation. In the present study, we identified five types of circulating haemocytes in larvae of the haemolymph of the Asian corn borer,

A comparison of the TC10™ automated cell counter and the hemocytometer for quantifying insect hemocytes. [PDF]

open access: yes, 2013
Hemocytes are an essential component of the invertebrate innate immune system (Strand 2008). Their close similarities to vertebrate white blood cells enable their use as a tractable model for immunological research. The quantification of hemocytes in the

Flow cytometric analysis of morphologic and immunological characterisation of the tiger shrimp Penaeus monodon haemocytes

open access: yesAquaculture Reports, 2021
Morphology and immune functions of Penaeus monodon haemocytes were analysed by flow cytometry (FCM). Basing on the relative size and granularity, there are three types of haemocyte identified by FCM, including hyaline cells (HC), semigranular cells (SGC)
