Morphological abnormalities of rabbit spermatozoa studied by scanning electron microscope and quantified by light microscope.
Rabbit spermatozoa morphological abnormalities were examined to establish criteria for judging the quality of ejaculates. Ten New Zealand White bucks, aged 9 months and weighing 4.3 +/- 0.2 kg, were placed in a climatic chamber for 3 weeks at +20 degrees C and 70% RH. Sperm was collected three times a week using an artificial vagina. The use of a scanning electron microscope (from x 2000 to x 1...

15 صفحه اولElectron Microscope Studies of Spermatozoa of Rhynchosciara Sp
The flagellar complex of the unusual motile spermatozoon of the fungus gnat, Rhynchosciara sp, does not conform to the usual "9 + 2" filament pattern but rather consists of over 350 pairs of filaments (doublet microtubules) distributed in a spiral array. Experiments were designed to disrupt and extract flagellar microtubular components from spermatozoa of the fungus gnat. Pepsin, chymotrypsin, ...
متن کاملMorphology of meningopneumonitis virus exposed to penicillin as observed with the electron microscope.
In a previous communication, Tajima et al. (1957) described how viruses of the psittacosislymphogranuloma group seem to have two different modes of multiplication in their developmental cycle. One is analogous to the intracellular development of pox viruses described by Morgan et al. (1954) and Tajima and Kubota (1956). In this mode, a pre-existing component of viral structure, the matrix, appe...
متن کاملMorphology of Escherichia coli Exposed to Penicillin as Observed with the Electron Microscope.
The morphological effects of penicillin on gram-negative nonsporeforming rods, especially E8cherichia coli, have been studied by several authors. Gardner (1940) reported that grotesque forms of E. coli resulted from autolytic swelling when this organism was treated with penicillin and that elongated, swollen cells resulted from incomplete fission. Weiss (1943) showed by electron micrographs tha...
