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 ...

Immunofluorescent reactions with microfilariae 2. Bearing on host-parasite relations

Transactions of the Royal Society of Tropical Medicine and Hygiene, 1977
Abstract A number of immunofluorescent reactions involving the sheath, cuticle and cytoplasm of microfilariae were studied on the supposition that although the antibodies involved are not lethal, the mechanisms affecting immunofluorescence might nevertheless be relevant to the problem of survival of microfilariae in the blood.

[Host-parasite relations].

Tijdschrift voor diergeneeskunde, 1987
Our current knowledge of the host-parasite relationship is reviewed as part of a series entitled 'Papers of yesterday and today'. A retrospective view is taken of a paper written in 1898 by Professor H. J. Hamburger, entitled 'The Current Point of View of the Theory of Natural Immunity', which is also published in a slightly abridged version in this ...

Interaction of Viruses and Bacteria in Host-Parasite Relations

New England Journal of Medicine, 1972
IT is apparent that we become colonized (or "infected") with only a small fraction of the many micro-organisms to which we are exposed, and that a still smaller percentage of such host-parasite interaction ever results in disease. The factors that determine "who amongst us are chosen" remain poorly defined.

Host-Parasite Relations in Agapema Pupae (Lepidoptera, Saturniidae)

Annals of the Entomological Society of America, 1956
In diapausing pupae of some saturniid moths, carbon dioxide is given off in brief “bursts” alternating with long periods in which the release rate is much lower (for literature see Buck and Keister, 1955). In studying this phenomenon some incidental observations were made which appear to have interesting implications in regard to host-parasite ...

Host-parasite relations and implications for control.

Advances in parasitology, 2009
This paper considers the various measures available to control several of the neglected tropical diseases (NTDs). To develop the optimum methods for controlling the parasites that cause these NTDs, knowledge of the life cycles of both the parasites and their vectors are essential.
