Identification of Relapsing Fever Spirochaetes
Many different opinions are observed if one compares the denomination of the species of relapsing fever spirochaetes by different authors. Brumpt (1) describes 14 different species in his extended Parasitology and Stitts (2) 18, but he admits the possibility of synonyms among them. Napier (3) mentions that the application of names of the countries in which the spirochaetes occur implicates the ...
متن کاملUnderstanding tropism and immunopathological mechanisms of relapsing fever spirochaetes.
Mice infected with relapsing fever (RF) spirochaetes survive recurrent waves of high-level bacteraemia with little, if any, clinical complications or tissue injury. In the absence of B-cells, peak bacteraemia does not resolve, resulting in multi-organ complications. During peak bacteraemia, large amounts of interleukin-10 (IL-10) are produced in blood and tissues. In mice unable to clear peak b...
متن کاملElectron Microscope Studies on the Haemoglobin Molecules
Haemoglobin molecules isolated from normal human subjects have been directly micrographed under the electron microscope following in general Hall's technique. The average height (h) and the widths along (w(11)) and perpendicular (w( perpendicular)) to the shadow direction of the molecules have been measured as 56.5 +/- 6.6 A, 122.7 +/- 15 A, and 120.9 +/- 20 A, respectively. The exaggeration in...
متن کاملElectron Microscope Studies on Blue-green Algae
Several species of blue-green algae were studied in thin sections with the electron microscope. Our electron micrographs confirm the view that the cell of blue-green algae is different and simpler in organization than the typical plant or animal cell. On the other hand, the general pattern of ultrastructure is the same as that found in bacteria and Streptomyces. The cell boundary is formed by a...
متن کاملLight and Electron Microscope Studies of Mycobacterium- Mycobacteriophage Interactions Ii. Electron Microscope Studies'
In the previous experiments (Takeya et al., 1959b) the interactions of Mycobacterium avium with mycobacteriophage B-1 were studied by cyttilogical techniques, and the latent period of the B-1 phage infecting the host cell was determined under the conditions used in the preparation for electron microscopy. The present paper deals with the results of experiments on the interactions of mycobacteri...
