Trypanosoma danilewskyi: Host Specificity and Host's Effect on Morphometrics

The Journal of Parasitology, 1984
Carassius auratus, Barbus conhus, Danio malabaricus, Catostomus commersoni, Notropis cornutus, Etheostoma caeruleum, and Ictalurus nebulosus were susceptible to Trypanosoma danilewskyi by intraperitoneal inoculation. Trypanosomes isolated from all species of susceptible fishes were infective to goldfish.

Host–Pathogen Specificity in Tuberculosis

2013
The host response to mycobacterial infection including tuberculosis depends on genetically controlled host and bacterial factors and their interaction. A largely unknown aspect of this interaction is whether disease results from an additive and independent effect of host and pathogen or from specific host-pathogen combinations.

Host specificity of avian coccidia

Parasitology Today, 1986
The term 'species specific' in reference to the host specificity of avian coccidia, has been used rather loosely for many years. A strong belief in strict species specificity has led to many new species of coccidia being described from oocysts isolated from the faeces of wild birds, primarily on the grounds that no coccidium had previously been ...

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.

The importance of host ecology in thelastomatoid (Nematoda: Oxyurida) host specificity

Parasitology International, 2006
An experimental investigation of host specificity within the Thelastomatoidea is presented by means of a comparison of the thelastomatoids of two panesthiine cockroaches, Panesthia cribrata and P. tryoni tryoni, with those of other log-dwelling arthropods and those of leaf litter dwelling arthropods found near by.

Host-specificity, host-exclusivity, and host-recurrence in saprobic fungi

Mycological Research, 2001
Estimates of global fungal numbers rely heavily on the ratios of unique fungi to host plants. Evidence for host-specificity, which is basic to our understanding of host to fungus ratios, is therefore explored in this review. There is considerable evidence that some endophytes, pathogens and mycorrhizal fungi are host-specific. Host-specificity however,

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 ...

Beta-specificity: The turnover of host species in space and another way to measure host specificity

International Journal for Parasitology, 2011
Host specificity is often measured as the number of host species used by a parasite, or as their phylogenetic diversity; both of these measures ignore the larger scale component of host use by parasites. A parasite may exploit very few host species in one locality but these hosts may be substituted for completely different species elsewhere; in ...

Experimental host specificity of Posthodiplostomum minimum

Experimental Parasitology, 1965
Abstract Parasite-free snails of the genus Physa were experimentally infected with the miracidia of Posthodiplostomum minimum, the metacercariae of which were originally obtained from bluegills, Lepomis macrochirus. Twelve species of fish representing 5 families (Cyprinidae, Cichlidae, Centrarchidae, Poeciliidae and Ictaluridae) were exposed to ...

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 ...
