Host specificity of the gut microbiome

Nature Reviews Microbiology, 2021
Developing general principles of host-microorganism interactions necessitates a robust understanding of the eco-evolutionary processes that structure microbiota. Phylosymbiosis, or patterns of microbiome composition that can be predicted by host phylogeny, is a unique framework for interrogating these processes.

Uncovering Mechanisms of Host Recognition, Host Finding and Host Specificity [PDF]

open access: yes
Insect diversification is thought to have been catalyzed by widespread specialization on novel hosts—a process underlying exceptional radiations of phytophagous beetles, lepidopterans, parasitoid wasps, and inordinate lineages of symbionts, predators, and other trophic specialists.

Physiological Host Specificity of Microsporidia as an Indicator of Ecological Host Specificity

Journal of Invertebrate Pathology, 1998
For most groups of biological control agents the relationship between laboratory (physiological) host range and the host range in the field (ecological host range) has not been explored empirically. The objective of our study was to investigate this relationship using the North America gypsy moth, Lymantria dispar, as a model nontarget host for ...

Host specificity of avian metapneumoviruses

Avian Pathology, 2019
To date, four subgroups of avian metapneumoviruses have been defined (AMPV-A, B, C and D) based on genetic and antigenic differences. The extent of infection in the three principal species (turkeys, chickens and ducks) by these subgroups is, however, not well defined.

Host Specificity in Subarctic Aphids

Environmental Entomology, 2017
Plants and herbivorous (or parasitic) insects form the majority of macroscopic life. The specificity of interaction between host plant and parasitic insect depends on the adaptations of both the host and the parasite. Over time, these interactions evolve and change as a result of an 'arms race' between host and parasite, and the resulting species ...

Tick-Host specificity

open access: yes, 1982
A review the various patterns of tick-host relationships are discussed in detail in order to answer the following questions : 1. How, when and where did host specificity of each parasite group evolve ? 2. How strict is specificity in each case ?

Insights in Bartonella Host Specificity

Annals of the New York Academy of Sciences, 2009
The genus Bartonella comprises a unique group of emerging gram‐negative, intracellular bacteria that can cause a long‐lasting intraerythrocytic bacteremia in their reservoir hosts. In recent years, the widespread occurrence and diversity of these bacteria has been increasingly recognized.
