Red Rust of Neoregelia Bromeliads Caused by a Parasitic Alga Cephaleuros parasiticus in Florida

Wheat leaf rust caused by Puccinia triticina.

UNLABELLED Leaf rust, caused by Puccinia triticina, is the most common rust disease of wheat. The fungus is an obligate parasite capable of producing infectious urediniospores as long as infected leaf tissue remains alive. Urediniospores can be wind-disseminated and infect host plants hundreds of kilometres from their source plant, which can result in wheat leaf rust epidemics on a continental ...

A Lack of Parasitic Reduction in the Obligate Parasitic Green Alga Helicosporidium

The evolution of an obligate parasitic lifestyle is often associated with genomic reduction, in particular with the loss of functions associated with increasing host-dependence. This is evident in many parasites, but perhaps the most extreme transitions are from free-living autotrophic algae to obligate parasites. The best-known examples of this are the apicomplexans such as Plasmodium, which e...

A Case of Chronic Appendicopathy Caused by Parasitic Infection

Parasitic infection of the appendix is rarely seen, but should be considered in patients with symptoms of chronic appendicitis. It is rarely associated with histological inflammation of the appendix, therefore radiographic imaging, performed during initial workup, remains unremarkable most of the time.
