Analysing Parallel Strategies to Alter the Host Specificity of Bacteriophage T7

open access: yesBiology, 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 ...

Horizontal transfer of parasitic sex ratio distorters between crustacean hosts [PDF]

open access: yes, 1998
Parasitic sex ratio distorters were artificially transferred within and between crustacean host species in order to study the effects of parasitism on host fitness and sex determination and to investigate parasite–host specificity. Implantation of Nosema

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

open access: yesVeterinary 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

open access: yesFrontiers 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]

open access: yesPLoS 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 ...

Absence of Behavioral Induction in Oviposition Preference of \u3ci\u3ePapilio Glaucus\u3c/i\u3e (Lepidoptera: Papilionidae) [PDF]

open access: yes, 2017
This study addressed the possible behaviora induction effects of previous exposure to several specific host plants on subsequent host preference hierarchy and specificity (i.e ..

STAT2 Limits Host Species Specificity of Human Metapneumovirus

open access: yesViruses, 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.

Increased sampling reveals novel lineages of Entamoeba: consequences of genetic diversity and host specificity for taxonomy and molecular detection. [PDF]

open access: yes, 2011
To expand the representation for phylogenetic analysis, ten additional complete Entamoeba small-subunit rRNA gene sequences were obtained from humans, non-human primates, cattle and a tortoise. For some novel sequences no corresponding morphological data

The Dual Function in Virulence and Host Range Restriction of a Gene Isolated from the pPATHEhg Plasmid of Erwinia herbicola pv. gypsophilae

open access: yesMolecular Plant-Microbe Interactions, 2000
The host range of the gall-forming bacterium Erwinia herbicola pv. gypsophilae (Ehg) is restricted to gypsophila whereas Erwinia herbicola pv. betae (Ehb) attacks beet as well as gypsophila.

Morphological and molecular studies of the nematode parasite Heterakis gallinarum (Heterakidae) infecting the cattle egret Bubulcus ibis (Ardeidae) [PDF]

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia, 2023
Parasites infecting migratory birds all over the world are still under investigation. The identification of parasitic taxa infecting ardeids was done concerning their morphological and morphometric features.
