Differential expression of immune defences is associated with specific host-parasite interactions in insects [PDF]

, 2009
Recent ecological studies in invertebrates show that the outcome of an infection is dependent on the specific pairing of host and parasite. Such specificity contrasts the long-held view that invertebrate innate immunity depends on a broadspectrum ...

Mortality during dispersal and the cost of host-specificity in parasites: how many aphids find hosts? [PDF]

, 1998
1. For a full assessment of explanations for the evolution of host-specificity it is necessary to estimate the probability that a dispersing parasite finds a host.

Host range, host specificity and hypothesized host shift events among viruses of lower vertebrates

Veterinary Research, 2011
The successful replication of a viral agent in a host is a complex process that often leads to a species specificity of the virus and can make interspecies transmission difficult.

Determinants of Host Range Specificity in Legume-Rhizobia Symbiosis

Frontiers in Microbiology, 2020
Leguminous plants possess the almost unique ability to enter symbiosis with soil-resident, nitrogen fixing bacteria called rhizobia. During this symbiosis, the bacteria physically colonize specialized organs on the roots of the host plant called nodules,

Zamilon, a novel virophage with Mimiviridae host specificity. [PDF]

PLoS ONE, 2014
Virophages, which are potentially important ecological regulators, have been discovered in association with members of the order Megavirales. Sputnik virophages target the Mimiviridae, Mavirus was identified with the Cafeteria roenbergensis virus, and ...

Analysing Parallel Strategies to Alter the Host Specificity of Bacteriophage T7

Biology, 2021
The recognition and binding of host bacteria by bacteriophages is most often enabled by a highly specific receptor–ligand type of interaction, with the receptor-binding proteins (RBPs) of phages being the primary determinants of host specificity ...

The Distribution of Mobile Genetic Elements (MGEs) in MRSA CC398 Is Associated with Both Host and Country. [PDF]

, 2011
Methicillin-resistant Staphylococcus aureus clonal complex (CC) 398 has emerged from pigs to cause human infections in Europe and North America. We used a new 62-strain S.

STAT2 Limits Host Species Specificity of Human Metapneumovirus

Viruses, 2020
The host tropism of viral infection is determined by a variety of factors, from cell surface receptors to innate immune signaling. Many viruses encode proteins that interfere with host innate immune recognition in order to promote infection.

A meta-analysis of host specificity in Neotropical hard ticks (Acari: Ixodidae) [PDF]

, 2013
Host specificity of Neotropical hard ticks (Acari: Ixodidae) was analyzed by using the number of hosts species for each tick species and the index of host specificity STD*, which integrates phylogenetic and ecological information. The analyses were based

Evolutionary and proximate mechanisms shaping host-parasite interactions : the case of "Daphnia magna" and its natural bacterial parasite "Pasteuria ramosa" [PDF]

, 2011
Host-parasite interactions are composed of a sequence of steps, all necessary for successful infection: parasites need to encounter their hosts, to enter into their bodies, and to proliferate within them. Selection will act on the mechanisms used in each
