Molecular mechanisms of drug resistance in natural Leishmania populations vary with genetic background [PDF]

open access: yes, 2012
The evolution of drug-resistance in pathogens is a major global health threat. Elucidating the molecular basis of pathogen drug-resistance has been the focus of many studies but rarely is it known whether a drug-resistance mechanism identified is ...

Natural Resistances to Viruses in Cucurbits [PDF]

open access: yesAgronomy, 2020
Cucurbit viruses cause considerable economic losses worldwide. The most common viral diseases affecting this crop family are Potyviruses, Cucumoviruses, Criniviruses, Ipomoviruses, Tobamoviruses, and the emerging Begomoviruses. Four main cucurbit crops are grown worldwide, namely melon, cucumber (Cucumis), watermelon (Citrullus), and squash (Cucurbita).

Variations in natural resistance to tuberculosis [PDF]

open access: yesJournal of Hygiene, 1960
1. ‘Resistant’ and ‘susceptible’ species of animals appear to be more or less equally susceptible to lung infection with equal doses of tubercle bacilli. Therefore it is pertinent to ask whether recognized natural differences in species resistant are in fact significant. For example, in terms of death rates (i.e. of overall resistance) the C57 mouse is

The age and evolution of an antiviral resistance mutation in Drosophila melanogaster [PDF]

open access: yes, 2007
What selective processes underlie the evolution of parasites and their hosts? Arms-race models propose that new host-resistance mutations or parasite counter-adaptations arise and sweep to fixation.

Parallel loss-of-function at the RPM1 bacterial resistance locus in Arabidopsis thaliana [PDF]

open access: yes, 2012
Dimorphism at the Resistance to Pseudomonas syringae pv. maculicola 1 (RPM1) locus is well documented in natural populations of Arabidopsis thaliana and has been portrayed as a long-term balanced polymorphism. The haplotype from resistant plants contains

Variation in costs of parasite resistance among natural host populations [PDF]

open access: yes, 2013
Organisms that can resist parasitic infection often have lower fitness in the absence of parasites. These costs of resistance can mediate host evolution during parasite epidemics. For example, large epidemics will select for increased host resistance. In

Naturally prion resistant mammals [PDF]

open access: yesPrion, 2012
Each known abnormal prion protein (PrP (Sc) ) is considered to have a specific range and therefore the ability to infect some species and not others. Consequently, some species have been assumed to be prion disease resistant as no successful natural or experimental challenge infections have been reported.

The integrated concept of disease resistance; a new view including horizontal and vertical resistance in plants [PDF]

open access: yes, 1977
Horizontal, uniform, race-non-specific or stable resistance can be discerned according to Van der Plank, from vertical, differential, race-specific or unstable resistance by a test in which a number of host genotypes (cultivars or clones) are tested ...
