Host Specificity in Variable Environments [PDF]
Host specificity encompasses the range and diversity of host species that a parasite is capable of infecting and is considered a crucial measure of a parasite's potential to shift hosts and trigger disease emergence. Yet empirical studies rarely consider that regional observations only reflect a parasite's 'realized' host range under particular ...

A call for phylogenetic context to understand geographic variation and host specificity in the parasitic copepod genus Salmincola [PDF]
Freshwater parasitic copepods appear to exhibit great taxonomic diversity. However, little is known about gene flow between species or whether there is incongruence between morphological and phylogenetic species definitions. Additionally, little is known

Molecular basis of host specificity in human pathogenic bacteria
Pathogenic bacteria display various levels of host specificity or tropism. While many bacteria can infect a wide range of hosts, certain bacteria have strict host selectivity for humans as obligate human pathogens. Understanding the genetic and molecular

High host specificity of alphacoronaviruses in Nearctic, insectivorous bats [PDF]
Bats are reservoir hosts for a number of coronaviruses, some of which may pose spillover risks for humans and other animals. We detected two alphacoronaviruses in big brown bats (Eptesicus fuscus) and little brown myotis (Myotis lucifugus) in Ontario ...

Sex-Specific Immune Responses Mediate Host Specificity in Hookworm Infections [PDF]
Hookworm infections affect 500–700 million people worldwide and can lead to chronic conditions, such as malnutrition and anemia. The challenge of managing these infections is heightened by the absence of effective vaccines and the potential for ...

Host Plant Specificity in Web-Building Spiders
Spiders are ubiquitous generalist predators playing an important role in regulating insect populations in many ecosystems. Traditionally they have not been thought to have strong influences on, or interactions with plants.

Understanding the origins and maintenance of host specificity, or why horizontally‐acquired symbionts associate with some hosts but not others, remains elusive.

Mapping the tail fiber as the receptor binding protein responsible for differential host specificity of Pseudomonas aeruginosa bacteriophages PaP1 and JG004. [PDF]
The first step in bacteriophage infection is recognition and binding to the host receptor, which is mediated by the phage receptor binding protein (RBP). Different RBPs can lead to differential host specificity.

Eriophyoid mites are highly host-specific, microscopic phytoparasites that primarily disperse to new hosts passively via wind. This seems paradoxical, as the likelihood of landing on an appropriate host species needed to survive appears low.
