Host-Parasite Relations in Some Pentastomida

The Journal of Parasitology, 1967
Pentastomida generally considered to reach adulthood in the respiratory systems of reptiles may attain precocious development in some of these definitive hosts. Sexually mature Kiricephalus pattoni and Porocephalus crotali have been recovered from serous cavities and tissues.

Host–parasite relations in mycoparasite. I. Fine structure of host, parasite, and their interface

Canadian Journal of Botany, 1971
A mycoparasite, Piptocephalis virginiana, shows resemblance to other fungal parasites of higher plants in the fine structure of hyphae and haustoria. The mode of penetration of the host cell, Choanephora cucurbitarum, probably involves mechanical forces. Although the presence of a cell wall degrading enzyme was not detected by conventional techniques,

Co-evolution in host-parasite relations

Die Kulturpflanze, 1988
The growth of interest recently in co-evolution of hosts and their parasites arises partly from the hope that a better understanding of the processes involved should provide new insights into disease control in agriculture. Unfortunately, examination of natural systems makes it immediately clear that they are often complex and that the host-parasite ...

Host-parasite relations in Lobatostoma manteri rohde (trematoda: aspidogastrea)

Zeitschrift f�r Parasitenkunde, 1973
Tissue reactions in the marine gastropods Cerithium moniliferum Kiener and Peristernia australiensis Reeve infected with the aspidogastrid Lobatostoma manteri are described. The former species harbours usually a single parasite coiled up in a cavity formed by the main and one (or some?) side ducts of the digestive gland, with metaplasia of the duct ...

The physiology of host-parasite relations

The Botanical Review, 1936
In reviewing the subject of parasitism from the physiological standpoint, little useful purpose would be served by confining attention to the literature of the last few years. References to the physiological relations of host and parasite are often of a casual nature, made in the course of investigations which had some other object in view, and even if

Host-Parasite Relations in Some Didymozoid Trematodes

The Journal of Parasitology, 1980
Adult Neometadidymozoon helicis and Nematobothrium spinneri were found coiled in host connective tissue without any capsule wall of parasite origin. Eggs of N. helicis and Didymozoon brevi- colle passed through the gut of a teleost without harm, suggesting predation as a possible mechanism for the release of eggs in these species.

Host-Parasite Relations in Spot Anthracnose of Desmodium

Mycologia, 1969
but not spongy parenchyma is invaded by hyphae when the pathogen enters a leaf via the upper epidermis; the reverse is true when it penetrates from the lower side. Only host cells close to hyphae show response. Mesophyll cells in the invaded region exhibit loss of chloroplasts, hyperplasia and hypertrophy; distinctive patterns of cell arrangement are ...

Host-Parasite Relations and Development of Elsinoë panici

Mycologia, 1987
Hyphae of Elsinoe panici Tiffany and Mathre penetrated between epidermal cells of Panicum virgatum L. and quickly formed stromata composed of darkly pigmented, firm, pseudoparenchymatous cells.

Some Physiological and Biochemical Aspects of Host-Parasite Relations

The Journal of Parasitology, 1970
The problems of the biochemical and physiological aspects of the host-parasite relationship have been explicitly separated from consideration of the physiology and biochemistry of the parasite. Certainly, the metabolic activities of the parasite will in part determine the nature of the relationship but it is most important that we recognize the host ...
