Estudo morfológico e quantitativo dos hemócitos em larvas de Diatraea saccharalis (Fabricius) (Lepidoptera, Pyralidae)
(Sociedade Brasileira de Zoologia, 1995-01-01)
Hemocytes of Diatraea saccharalis larvae aging from 13 to 26 days old were morphological and quantitatively characterized by phase contrast microscopy. Six hemocyte types were described and identified as: prohemocytes (PR), ...
The role of hemocytes in the immunity of the spider Acanthoscurria gomesiana
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
Invertebrates protect themselves against microbial infection through cellular and humoral immune defenses. Since the available information on the immune system of spiders is scarce, the main goat of the present study was ...
Differences in the number of hemocytes in the snail host Biomphalaria tenagophila, resistant and susceptible to Schistosoma mansoni infection
(Funpec-editora, 2010-01-01)
The relationships between schistosomiasis and its intermediate host, mollusks of the genus Biomphalaria, have been a concern for decades. It is known that the vector mollusk shows different susceptibility against parasite ...
Defense reactions of Dermatobia hominis (Diptera : Cuterebridae) larval hemocytes
(Inst Histol Embriol-conicet, 2003-08-01)
The defense reactions against biological (Histoplasma capsulatum and Escherichia coli) and non-biological materials (China ink and nylon thread) were tested in vivo in third instar larvae of Dermatobia hominis. The cellular ...
Differential morphology of the hemocytes present in pupal ovaries of the queen and worker honeybee
(2001-12-01)
The location and morphological features of the blood cells found in the pupal ovary of workers and queens of Apis mellifera are described in relationship with their probable function in the ovary differentiation. The ...
Defense reactions of Dermatobia hominis (Diptera: Cuterebridae) larval hemocytes
(2003-09-18)
The defense reactions against biological (Histoplasma capsulatum and Escherichia coli) and non-biological materials (China ink and nylon thread) were tested in vivo in third instar larvae of Dermatobia hominis. The cellular ...
Ultrastructural and cytochemical characterization of hemocytes in diatraea saccharalis (Lepidoptera:Pyralidae) larvae parasitized by the wasp cotesia flavipes (Hymenoptera:Braconidae)
(2014-08-15)
This study describes the morphology of the hemocytes in Diatraea saccharalis larvae during parasitism by the wasp Cotesia flavipes, determined by transmission electron microscopy using conventional and cytochemical techniques. ...
Impact of low temperatures on the immune system of honeybees
(2021-10-01)
Changes in temperature resulting from climate change can impact the distribution and survival of species, including bees, where temperature may also affect their immune system. Evaluation of immune system activity is often ...
Hemócitos fagocitários em larvas de Diatraea saccharalis (Fabricius) (Lepidoptera, Pyralidae)
(Sociedade Brasileira de Zoologia, 1995-01-01)
The ultrastructural observation of the hemocytes of D. saccharalis larvae showed different hemocyte tvpes in various stage of interaction with microorganisms, which were interpreted as bacteria. The microorganisms were ...
An in vitro method for studying subcellular rearrangements during cell polarization in Drosophila melanogaster hemocytes
(Elsevier Ireland Ltd, 2018)
© 2018Thanks to the power of Drosophila genetics, this animal model has been a precious tool for scientists to uncover key processes associated to innate immunity. The fly immune system relies on a population of macrophage-like ...
