Kinetoplastids: related protozoan pathogens, different.

Typically, the kinetoplastids are depicted as long slender organisms. However, the kinetoplastids exhibit several morphological forms which are defined by the position of the kinetoplast in relation to the nucleus and the length of the undulating membrane (see morphological forms).Cellular features of the kinetoplastids include:. A single flagellum present in many of the morphological forms.

Kinetoplastids (Kinetoplastea) are a widespread and very important group of obligatory parasitic protists. At least one stage in the life cycle of all members of this group is represented by a slender and highly flexible cell equipped with one or two flagella, arising from a prominent flagellar pocket. Another hallmark is the presence of extensive mitochondrial DNA, termed kinetoplast DNA and.

A kinetoplast is a network of circular DNA (called kDNA) inside a large mitochondrion that contains many copies of the mitochondrial genome. The most common kinetoplast structure is a disk, but they have been observed in other arrangements. Kinetoplasts are only found in Excavata of the class Kinetoplastida. The variation in the structures of kinetoplasts may reflect phylogenic relationships.The kinetoplastids are a group of single-cell flagellate eukaryotes.They include a number of parasites responsible for serious diseases in humans and other animals. There are also forms found in soil and aquatic environments. They are members of the phylum Euglenozoa. Their main distinguishing feature is the presence of a kinetoplast, a DNA-containing granule inside the single mitochondrion.The kinetoplast is situated close to the nucleus, and its shape and structural organization vary according to the developmental stage of the protozoan. The trypanosomatids possess a unique and highly ramified mitochondrion. The kinetoplast appears as a dense structure and is made of kinetoplast DNA (kDNA), found in a specialized portion of the mitochondrion (Fig. 18.4) within the mitochondrial.
