D. latum Infection and Characteristics
- Humans become infected with Diphyllobothrium latum (D. latum) through the consumption of raw or undercooked freshwater fish that contain the larvae.
- D. latum eggs are oval and measure approximately 70-80 micrometers in length and 40-60 micrometers in width, featuring a characteristic operculum at one or both ends.
- The embryos of D. latum emerge from the eggs in freshwater, hatching and then developing into free-swimming larvae called coracidia.
- Diphyllobothrium latum is notable for having proglottids that are wider than they are long, distinguishing it from other tapeworms.
- D. latum can grow up to 10 meters in length, making it the world's longest tapeworm species.
