ANKYLOSTOMA DUODENALE Meaning and
Definition
-
Ankylostoma duodenale is a parasitic nematode worm that belongs to the family Ancylostomatidae. Commonly known as the human hookworm, it is one of the two main species of hookworm that infects humans, with the other being Necator americanus.
Ankylostoma duodenale has a small, slender body, measuring around 10-13mm in length. It possesses a characteristic hook-like mouthpart, which it uses to attach itself to the intestinal wall of its host. The worm primarily infects the duodenum, the first part of the small intestine, hence its scientific name.
The infection caused by Ankylostoma duodenale is known as ankylostomiasis or hookworm disease. It occurs when the larval form of the worm penetrates the skin, usually through contact with contaminated soil. The larvae then migrate through various tissues, eventually reaching the intestine where they mature into adult worms.
Symptoms of an infection with Ankylostoma duodenale may include abdominal pain, diarrhea, weight loss, fatigue, and anemia. The worm feeds on blood from the host, which can lead to iron deficiency anemia over time. Severe cases of ankylostomiasis can result in stunted growth and cognitive impairments, particularly in children.
Preventive measures against Ankylostoma duodenale include practicing good hygiene, wearing protective footwear when in areas at risk of contamination, and avoiding contact with infected soil. Treatment usually involves anthelmintic medications that effectively kill the worms and alleviate symptoms.
Etymology of ANKYLOSTOMA DUODENALE
The word "Ankylostoma duodenale" has its etymology rooted in Greek.
The genus name "Ankylostoma" is derived from the Greek words "ankylos" meaning "crooked" or "bent" and "stoma" meaning "mouth". This refers to the fact that the parasite has a curved mouth structure.
The species name "duodenale" is derived from the Latin word "duodenum", which means "twelve". The term "duodenale" indicates that the parasite is commonly found in the duodenum, which is the first part of the small intestine.
Hence, "Ankylostoma duodenale" refers to a species of parasitic worm that has a curved mouth and typically resides in the duodenum. This species is commonly known as the human hookworm.
