Parasitism, Host Species Specificity, and Gene-Specific Host Cell Death

1991
The development of biological control agents for the control of weeds is only in its infancy, and its success as an applied science will parallel and be limited by progress made in our understanding of the basic genetic and pathological sciences. The better our understanding of the structure, function, and expression of genes affecting plant-microbe ...

Host Specificity in Xanthomonas

Nature, 1958
Burkholder and Starr1 stated that “unequivocal identification by laboratory procedures of all Xanthomonas species is as yet an impossibility”, and there has been no change in this position in recent years2,3. The diagnosis of Xanthomonas species therefore depends on the host specificity of the organisms.

Mycoplasma host specificity: Fact or fiction?

The Veterinary Journal, 2005
Bacteria of the genus Mycoplasma are the smallest organisms known to be capable of self-replication. They only occur in association with animal host cells on which they are dependant for many pre-formed nutrients since they lack many of the metabolic pathways associated with energy production and the synthesis of cell components found in other species ...

Intermediate host specificity in Schistosoma mansoni

Experimental Parasitology, 1976
Abstract Miracidia of Schistosoma mansoni penetrate into many kinds of snails, but development of normal sporocysts takes place only in certain species of Biomphalaria . Different populations of this snail vary greatly in laboratory infection rates with S. mansoni originating from diverse geographic localities.

The host specificity of monogenetic trematodes

Experimental Parasitology, 1957
Abstract The host-parasite relations of the 75 species of Monogenea in the present collection and many more from the literature have been considered and the following conclusions reached: 1. 1. The species studied, and probably most other Monogenea, are highly host-specific. 2. 2.

Host specificity and speciation

1985
Most aphids are autoecious (Figure 3.1), living on one or a few species of a particular genus of plants (Eastop, 1973). About 10% are heteroecious (Figure 3.1), spending autumn, winter and spring on a primary host plant, and the summer on a secondary host plant(s), which is rarely closely related to the primary host. For example the primary host of the

Host-Specificity and Specificity of Animal Parasites

The American Journal of Tropical Medicine, 1933
Summary The dual conception that a particular parasite species is limited to a single host species and that a particular host species may harbor but one species of a particular general group is obsolete. Selected examples from among the protozoa, worms, and arthropods support the two following generalizations: (1) A particular parasite will develop ...
