Protozoology, the study of protozoans.
September 23, 1850 Friedberg, Germany October 3, 1937 Munich, Germany Richard von Hertwig, (born September 23, 1850, Friedberg, Hessen died October 3, 1937, Munich) German biologist particularly noted for the development of the germ-layer theory, which proposes that all organs and tissues are derived variously from three basic tissue layers, and for his contributions to the study of protozoans.
With the notable exception of metacaspase proteins, however, in silico studies of protozoan genomes have failed to detect the key components of apoptosis such as Bcl-2, BAX, apoptosis-inducing factor and other effectors and regulators.
Hsp70 genes and proteins have also been used for phylogenetic studies of different protozoan parasites such as Trypanosoma or Leishmania[ 14, 15], as well as of non-parasitic protozoans such as Euplotes or Paramecium[ 16, 17].
In the first instance, hybrid capture methods may be applied for population genomic study of several bacterial, protozoan, or viral pathogens co-vectored by the same blacklegged tick vector such as Anaplasma phagocytophilum, Babesia microti, and Powassan virus [ 45– 49] using a multiple-pathogen capture array.
Genetic studies of the protozoan parasite Toxoplasma gondii have identified three main distinct types according to virulence in some hosts.
Resemblances in functional capacity in transcriptome-wide studies of other protozoan groups are not uncommon [ 46, 47].
In studies of the protozoan Tetrahymena pyriformis, additional details regarding the substrate specificity for 22-SD were established, and rules of substrate recognition that govern the introduction of the Δ-bond were described.
April 5, 1801 Tours, France April 8, 1860 Rennes, France Félix Dujardin, (born April 5, 1801, Tours, Fr. died April 8 , 1860 Rennes) French biologist and cytologist, noted for his studies in the classification of protozoans and invertebrates.
Protozoans also excrete nitrogen and phosphorus, in the form of ammonium and orthophosphate, as products of their metabolism, and studies have shown that the presence of protozoans in soils enhances plant growth.
The only blood parasites found in a study of blackcaps trapped on migration were protozoans from the genera Haemoproteus and Plasmodium.
