Since several species of Schistosoma, or blood fluke, parasitize man, these trematodes have been subjected to extensive study. Light microscopy and conventional electron microscopy have yielded much information about the morphology of the various stages; however, scanning electron microscopy has been little utilized for this purpose. As the figures demonstrate, scanning microscopy is particularly helpful in studying at high resolution characteristics of surface structure, which are important in determining host-parasite relationships.

Brown Color

The morphology of eggs and first instar larvae of Croce schmidti (Navás, 1927) is described and figured for the first time using light and scanning electron microscopy. The females were collected from Derik, Mardin Province, Turkey and maintained in the laboratory. The eggs are elongate and cylindrical with rounded ends and bear a small terminal micropylar knob. Except for the adhesive materials, the chorion surface is smooth. The newly emerged larva of C. schmidti is characterized by a slightly quadrangular head and short prothorax and has prominent pale dark brown color markings on the metatergites. The body is covered with short brown setae, which include macrotrichia and dolichasters.

Study Development

A species of Phyllactinia on oak was examined by scanning electron microscopy. The naturally dried fungus was minimally manipulated in preparation for study. Development was followed by examining various stages from initial to mature perithecium. Immature perithecial appendages were found to be less rigid than those which had matured. The sticky apical mucilage droplet on the maturing perithecium was observed, but the penicillate cells that form the droplet were not easily seen. As the appendages dried they lifted the perithecium off the surrounding surface. Some perithecia were found that had overturned and adhered to the hyphae-covered leaf by means of the mucilage droplet. This study has resulted in visualization of Phyllactinia surface structure in more detail than heretofore reported. Other plant pathogenic fungi, especially those producing naturally dry mature fruiting bodies, should be amenable to study by this method.
