Metazoan-protozoan parasite co-infections and host body weight in St Kilda Soay sheep [PDF]

open access: yes, 2008
For hundreds of years, the unmanaged Soay sheep population on St Kilda has survived despite enduring presumably deleterious co-infections of helminth, protozoan and arthropod parasites and intermittent periods of starvation.

Canonical and variant histones of protozoan parasites [PDF]

open access: yes, 2011
Protozoan parasites have tremendously diverse lifestyles that require adaptation to a remarkable assortment of different environmental conditions. In order to complete their life cycles, protozoan parasites rely on fine-tuning gene expression. In general,

The cytoskeleton of protozoan parasites

open access: yesCurrent Opinion in Cell Biology, 1996
There are seven processes that require a cytoskeleton in protozoan parasites: nuclear division, cytokinesis, cell shape determination, motility, invasion, flagellar movement of sperm, and intracellular transport.

H+-translocating pyrophosphatases in protozoan parasites. [PDF]

open access: yesParasitol Res
AbstractIntegral membrane pyrophosphatases (mPPases) hydrolyze pyrophosphate. This enzymatic mechanism is coupled with the pumping of H + and/or Na + across membranes, which can be either K + -dependent or K + -independent. Inorganic proton–translocating pyrophosphatases (H + -PPases) can transport protons across cell membranes and are reported in ...

Molecular and phylogenetic characterization of honey bee viruses, Nosema microsporidia, protozoan parasites, and parasitic mites in China [PDF]

open access: yes, 2013
China has the largest number of managed honey bee colonies, which produce the highest quantity of honey and royal jelly in the world; however, the presence of honey bee pathogens and parasites has never been rigorously identified in Chinese apiaries.

Characterisation of tabanid flies (Diptera: Tabanidae) in South Africa and Zambia and detection of protozoan parasites they are harbouring [PDF]

open access: yes, 2017
Tabanids are haematophagous flies feeding on livestock and wildlife. In the absence of information on the relationship of tabanid flies and protozoan parasites in South Africa and Zambia, the current study was aimed at characterizing tabanid flies ...

Prevalences and trends of human oral protozoan parasites

open access: yesOrapuh Journal, 2020
Protozoan parasites are microscopic, unicellular organisms, of a group of phyla of the kingdom Protista, that can be free-living or parasitic. These organisms can live, and reproduce their kind, in human tissues.

Comparative Pathobiology of the Intestinal Protozoan Parasites Giardia lamblia, Entamoeba histolytica, and Cryptosporidium parvum. [PDF]

open access: yes, 2019
Protozoan parasites can infect the human intestinal tract causing serious diseases. In the following article, we focused on the three most prominent intestinal protozoan pathogens, namely, Giardia lamblia, Entamoeba histolytica, and Cryptosporidium ...
