Study Notes
- Chilomastix mesnili is classified under the phylum Protozoa and class flagellatae
Laboratory Diagnosis
- Stool examination involves direct smear and iodine or normal saline for examination of trophozoite in diarrheic stool and cyst-formed stool
General characteristics
- Disease caused by Chilomastix mesnili is nonpathogenic
- Habitat is the large intestine
- Humans are the final host
- The infective stage is the cyst
- Infection occurs orally by ingesting mature cysts in contaminated food and water
- Stool sample is used for diagnosis
- The diagnostic stage includes both trophozoite and cyst stages
- The morphology has two stages
Trophozoite
- Pear or oval shape
- Contains one nucleus
- Contains a spiral groove and cytostome
- Has 3 anterior flagella
