Host Specificity in Variable Environments [PDF]

open access: yesTrends in Parasitology, 2019
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]

open access: yesParasitology
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

Sex-Specific Immune Responses Mediate Host Specificity in Hookworm Infections [PDF]

open access: yesTropical Medicine and Infectious Disease
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 ...

High host specificity of alphacoronaviruses in Nearctic, insectivorous bats [PDF]

open access: yesnpj Viruses
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 ...

Host Plant Specificity in Web-Building Spiders

open access: yesInsects, 2023
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.

Plant abundance, but not plant evolutionary history, shapes patterns of host specificity in foliar fungal endophytes

open access: yesEcosphere, 2022
Understanding the origins and maintenance of host specificity, or why horizontally‐acquired symbionts associate with some hosts but not others, remains elusive.

Vertical transmission and seasonal dimorphism of eriophyoid mites (Acariformes, Eriophyoidea) parasitic on the Norway maple: a case study

open access: yesRoyal Society Open Science, 2022
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.

Effects of Phycosphere Bacteria on Their Algal Host Are Host Species-Specific and Not Phylogenetically Conserved

open access: yesMicroorganisms, 2022
Phytoplankton is fundamental to life on Earth. Their productivity is influenced by the microbial communities residing in the phycosphere surrounding algal cells.

New host and distribution records of the gill parasite Dactylogyrus sphyrnoides Gussev, 1976 (Platyhelminthes, Monogenoidea) on a Near Threatened Tor Barb, Tor tor (Hamilton, 1822) (Teleostei, Cyprinidae), in northeastern India [PDF]

open access: yesCheck List, 2016
The parasitic monogenoid Dactylogyrus sphyrn­oides Gussev, 1976 was recorded for the first time on the gills of the Near Threatened freshwater fish Tor tor (Hamilton, 1822) that was collected in northeastern India. Dactylogyrus sphyrnoides was originally

A Single Amino Acid of NIaPro of Papaya ringspot virus Determines Host Specificity for Infection of Papaya

open access: yesMolecular Plant-Microbe Interactions, 2008
Most strains of Papaya ringspot virus (PRSV) belong to type W, causing severe loss on cucurbits worldwide, or type P, devastating papaya in tropical areas.
