The Role of Birds of the Family Corvidae in Transmitting Sarcocystis Protozoan Parasites

open access: yesAnimals, 2021
Members of the family Corvidae are ecologically flexible omnivorous birds, particularly adaptive to urban habitats, and living in proximity to humans; these birds may serve as definitive hosts (DH) for Sarcocystis spp., but research about this is lacking.

Molecular confirmation of Sarcocystis fayeri in a donkey [PDF]

open access: yes, 2017
Sarcocystis fayeri is a canine protozoan parasite with an equine intermediate host. Historically classified as an incidental pathogen, recent literature has described the toxic effects of Sarcocystis fayeri in human food poisoning, and highlighted ...

STUDIES ON THE BIOLOGY OF BULINUS TRUNCATUS UNDER LABORATORY CONDITIONS [PDF]

open access: yesIranian Journal of Public Health, 1976
A two-year laboratory study on the biology (including self-fertilization) of Bulinus truncatus, the intermediate host of Schistosoma haematobium, S. bovis and Paramphistomum microbotrium in Iran, has revealed information on the longevity, reproduction ...

What makes a host profitable? Parasites balance host nutritive resources against immunity [PDF]

open access: yes, 2008
Numerous host qualities can modulate parasite fitness, and among these, host nutritive resources and immunity are of prime importance. Indeed, parasite fitness increases with the amount of nutritive resources extracted from the host body and decreases ...

Behavior out of control: experimental evolution of resistance to host manipulation [PDF]

open access: yes, 2019
Many parasites alter their host's phenotype in a manner that enhances their own fitness beyond the benefits they would gain from normal exploitation. Such host manipulation is rarely consistent with the host's best interests resulting in suboptimal and ...

Composition and divergence of coronavirus spike proteins and host ACE2 receptors predict potential intermediate hosts of SARS‐CoV‐2

open access: yesJournal of Medical Virology, 2020
From the beginning of 2002 and 2012, severe respiratory syndrome coronavirus (SARS‐CoV) and Middle East respiratory syndrome coronavirus (MERS‐CoV) crossed the species barriers to infect humans, causing thousands of infections and hundreds of deaths ...

The Potential Intermediate Hosts for SARS-CoV-2

open access: yesFrontiers in Microbiology, 2020
The coronavirus disease 19 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has become a global pandemic since the first report in Wuhan. COVID-19 is a zoonotic disease and the natural reservoir of SARS-CoV-2 seems to be

The dust masses of powerful radio galaxies: clues to the triggering of their activity [PDF]

open access: yes, 2014
We use deep Herschel Space Observatory observations of a 90% complete sample of 32 intermediate-redshift 2Jy radio galaxies (0.05 < z < 0.7) to estimate the dust masses of their host galaxies and thereby investigate the triggering mechanisms for their ...

The pig as an amplifying host for new and emerging zoonotic viruses

open access: yesOne Health, 2022
Pig production is a rapidly growing segment of the global livestock sector, especially in Asia and Africa. Expansion and intensification of pig production has resulted in significant changes to traditional pig husbandry practices leading to an ...

Phase stability and dynamics of entangled polymer-nanoparticle composites. [PDF]

open access: yes, 2015
Nanoparticle-polymer composites, or polymer-nanoparticle composites (PNCs), exhibit unusual mechanical and dynamical features when the particle size approaches the random coil dimensions of the host polymer.
