Scanning electron microscopy of the eggs of three human schistosomes.

FORD J. W. and BLANKESPOOR H. D. 1979. Scanning electron microscopy of the eggs of three human schistosomes. Znternational Journalfor Parasitology 9: 141-145. The surface of the eggs of Schistosoma haematobium, S. japonicum and S. mansoni, examined by scanning electron microscopy, are covered with microspines. The spines of S. mansoni and S. haematobium are essentially similar; however, in S. j...

Scanning Electron Microscopy of Human

I t is now generally accepted that two distinct classes of lymphocytes are present in different species including man--thymus-derived (T) cells and bone marrow or bursalderived (B) cells (1, 2). Although similar in appearance these two cell types have been demonstrated to have widely different functions. They can be distinguished electrophoretically by their different mobility (3, 4), serologic...

[Scanning electron microscopy of eggs of Haemagogus leucocelaenus (Diptera: Culicidae)].

OBJECTIVE To observe morphological details of the eggs of Haemagogus (Conopostegus) leucocelaenus, seen for the first time via scanning electron microscopy (SEM), with morphometric analysis of the main structures. METHODS Eggs of Hg. leucocelaenus were obtained from females captured in the Biological Reserve of Tinguá, State of Rio de Janeiro. Some of the eggs were kept for hatching and other...

Scanning electron microscopy of human liver sinusoids.

Hepatic sinusoids of human liver samples obtained by surgical or needle biopsy were examined under the scanning and transmission electron microscopes (SEM and TEM). The surgically obtained tissues were perfused, by the use of a needle and syringe, with Ringer solution and successively with glutaraldehyde solution through the cut ends of blood vessels, while the needle biopsy pieces were perfuse...

Scanning Electron Microscopy (SEM) analysis and biological control of Ixodes ricinus using entomopathogenic fungi

In the present study, pathogenicity of four native strains of Entomopathogenic fungus; Metarhizium anisopliae, was studied against adult stage of Ixodes ricinus. For this purpose a total number of 180 adult ticks were examined in triplicate. Thirty ticks for each strain and negative and positive controls were immersed in 2.4×107 fungal conidia/ml in vitro. Samples were incubated in separate Pet...
