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,

Stochastic spatial models of host-pathogen and host-mutualist interactions I

open access: yes, 2006
Mutualists and pathogens, collectively called symbionts, are ubiquitous in plant communities. While some symbionts are highly host-specific, others associate with multiple hosts.

A comprehensive survey of Rhinonyssid mites (Mesostigmata: Rhinonyssidae) in Northwest Russia: New mite-host associations and prevalence data [PDF]

open access: yes, 2020
Background: Rhinonyssid mites are permanent parasites of birds that inhabit their respiratory tract. There are around 600 species described worldwide and almost all species of birds are found to have embedded rhinonyssid mites.

Molecular characterisation of human penile carcinoma and generation of paired epithelial primary cell lines

open access: yesMolecular Oncology, EarlyView.
Generation of two normal and tumour (cancerous) paired human cell lines using an established tissue culture technique and their characterisation is described. Cell lines were characterised at cellular, protein, chromosome and gene expression levels and for HPV status.

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.

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.

Strength through diversity: how cancers thrive when clones cooperate

open access: yesMolecular Oncology, EarlyView.
Intratumor heterogeneity can offer direct benefits to the tumor through cooperation between different clones. In this review, Kuiken et al. discuss existing evidence for clonal cooperativity to identify overarching principles, and highlight how novel technological developments could address remaining open questions.

The development of techniques to distinguish species and strains of giardia : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Microbiology at Massey University [PDF]

open access: yes, 1995
Water supplies, in some rural areas of New Zealand, contain Giardia cysts. This is assumed to make the water unsuitable for human consumption. G. intestinalis and/or G. muris cysts may be present but are not distinguished by the standard test. G.

ATF4‐mediated stress response as a therapeutic vulnerability in chordoma

open access: yesMolecular Oncology, EarlyView.
We screened 5 chordoma cell lines against 100+ inhibitors of epigenetic and metabolic pathways and kinases and identified halofuginone, a tRNA synthetase inhibitor. Mechanistically halofuginone induces an integrated stress response, with eIF2alpha phosphorylation, activation of ATF4 and its target genes CHOP, ASNS, INHBE leading to cell death ...

open access: yes, 2019
Nasal nematodes of the genus Skrjabingylus occur in the mammalian families Mustelidae and Mephitidae, and have been found from Canada to Costa Rica.
