ASCARIS ALATA Meaning and
Definition
-
Ascaris alata, also known as the Alate roundworm, is a species of parasitic roundworm that commonly infects the small intestines of humans and animals. This species belongs to the phylum Nematoda and the family Ascarididae. It is one of the largest and most prevalent species of roundworms found worldwide.
Adult Ascaris alata worms are cylindrical in shape and can reach a length of up to 35 centimeters. They have a smooth, whitish-pink body with a distinct tapered tip. The male worms possess a curved posterior end with two spicules, while the females have a straight posterior end with a rounded tip. These worms have a simple digestive system, with a mouth at the anterior end and an anus at the posterior end.
Infestation occurs through the ingestion of Ascaris alata eggs, which are often present in contaminated soil, water, or food. Once ingested, the eggs hatch in the small intestine and release larvae, which penetrate the intestinal wall and migrate through the bloodstream to other organs, primarily the lungs. In the lungs, the larvae develop further, eventually migrating back to the small intestine, where they mature into adult worms and reproduce.
Infections caused by Ascaris alata can lead to various symptoms, including abdominal pain, diarrhea, weight loss, anemia, and malnutrition. Severe infestations can potentially cause intestinal blockage or obstruction. Treatment usually involves anti-parasitic medication, such as albendazole or mebendazole.
Preventive measures, such as improved sanitation, proper hand hygiene, and the avoidance of ingestion of contaminated food and water, are crucial in reducing the risk of Ascaris alata infection.
Etymology of ASCARIS ALATA
The etymology of the word "Ascaris alata" can be broken down as follows:
1. Ascaris: This term comes from the Greek word "áskaris", which means "intestinal worm". It originated from the Sanskrit word "kṛmi" meaning "worm".
2. Alata: The word "alata" is derived from the Latin word "alatus", which translates to "winged". This term was chosen because the female Ascaris alata worm possesses a characteristic wing-like appendage on its tail.
So, when combined, "Ascaris alata" refers to a specific species of intestinal worm that bears wings or wing-like structures.
