The Evolution of Host‐Parasite Range

The American Naturalist, 2010
Understanding the coevolution of hosts and parasites is one of the key challenges for evolutionary biology. In particular, it is important to understand the processes that generate and maintain variation. Here, we examine a coevolutionary model of hosts and parasites where infection does not depend on absolute rates of transmission and defense but is ...

Poxviruses and the evolution of host range and virulence [PDF]

open access: yesInfection, Genetics and Evolution, 2014
Poxviruses as a group can infect a large number of animals. However, at the level of individual viruses, even closely related poxviruses display highly diverse host ranges and virulence. For example, variola virus, the causative agent of smallpox, is human-specific and highly virulent only to humans, whereas related cowpox viruses naturally infect a ...

Host-Range of Lactobacillus Bacteriophages

Nature, 1960
IN 1955, Kiuru and Tybeck1 isolated a phage specific for 1 strain of Lactobacillus lactis and a phage working on 2 strains of L. helveticus. These phages were isolated from cultures used in the manufacture of Swiss cheese. In 1958, Meyers et al. 2 reported the isolation from saliva of phages active on 7 Lactobacillus species.

Host range ofFrankia endophytes

Plant and Soil, 1985
Cross-inoculation experiments with 10 pure cultured strains and 17 host species were carried out. The 10 strains were isolated from the root nodules on actinorhizal trees ranging in 9 species, 5 genera and 4 families. The host species belong to 5 genera.

SIGNALING AND HOST RANGE VARIATION IN NODULATION

Annual Review of Microbiology, 1992
Rhizobium, Bradyrhizobium, and Azorhizobium strains, collectively referred to as rhizobia, elicit on their leguminous hosts, in a specific manner, the formation of nodules in which they fix nitrogen. Rhizobial nod genes, which determine host specificity, infection, and nodulation, are involved in the exchange of low molecular weight signal molecules ...

Baculovirus host-range

Virologica Sinica, 2009
Baculoviruses are used as microbial insecticides, protein expression vectors, epitope display platforms, and most recently as vectors for gene therapy. Understanding the mechanisms that control baculovirus host-range and tissue tropisms are important for assessing their safety and for improving their properties for these biotechnology applications.

The host range of the genusXanthomonas

The Botanical Review, 1984
Compilation of information from the literature and from our own results has revealed thatXanthomonas infections occur on at least 124 monocotyledonous and 268 dicotyledonous plant species. There are no reports about infections on gymnosperms or lower plants.

Exploring the open (host) range

Cell Host & Microbe
The report from Grenz et al. in the latest issue of Cell Host & Microbe demonstrates how incorporation of phenotypic, genetic, genomic, and evolutionary information into experimental design provides a more complete picture than focusing on single host-pathogen relationships.

Cycliophoran Host Range

Bulletin of the Peabody Museum of Natural History, 2012
ABSTRACT Cycliophorans represent a phylum of small multicellular animals previously recorded only from the mouthparts of three species of lobsters in the family Nephropidae. In a survey of museum material representing a broad sampling of crustacean taxa, cycliophorans were found on several nephropid specimens but on specimens of no other crustacean ...
