Identifying features are:
- Microscopic, unicellular eukaryotic organism.
Irregular or definite body shape.
Locomotory organelles pseudopodia,cilia or flagella.
Hence, the specimen belongs to the Kingdom: Protozoa.
- Monomorphic type of nucleus.
- Presence of flagella, Pseudopodia or both.
- No spore formation.
- Sexual reproduction, if present, essentially syngamy.
Hence,the specimen belongs to the Phylum: Sarcomastigophora
- Locomotory organs flagella one or more.
- Pellicle is formed by a thin, firm, elastic outer layer of ectoplasm.
Hence, the specimen belongs to the Sub Phylum: Mastigophora
- Locomotory organs are flagella one or more.
- Chromatophores absent. Amoeboid forms with or without flagella.
- Pellicle is present.
- Single mitochondrion extending whole length of body as single tube, hoop, or network of branching tubes.
- Presence of an undulating membrane.
- A single nucleus.
- Presence of Kinetoplast near flagellar kinetosomes.
Hence, the specimen belongs to the Order: Kinetoplastida
- Length of the Body is 15-34 um, width 1.5-3.0um.
- Highly flattened body fusiform, pointed at the flagellar end & bluntly rounded or pointed at the other end.
- Nucleus central. It contains a large central nucleolus; endoplasmic reticulum appear to project out from the nuclear membrane.
- A single flagellum arises from the basal blepheroplast and runs along the free edge of a well-developed undulating membrane.
- Flagellum is free at the anterior end of the body.
- Stumpy form may appear sporadically.
Hence, the specimen seems to be Trypanosoma sp
