Kidney worm refers to a parasitic roundworm that primarily affects the kidneys of various animal species, including mammals and birds. This worm, scientifically known as Dioctophyma renale, belongs to the family Dioctophymatidae. Its name, derived from the Greek words "di" (two), "okto" (eight), and "phyma" (a growth), reflects its characteristic cylindrical shape adorned with eight enlarged lips.
Kidney worms are predominantly found in the urinary system, specifically within the renal pelvis and tubules of the kidneys. It is not uncommon for these worms to attain a length of up to 1 meter (3 feet) in some cases, making them one of the largest known roundworm species. They are dioecious organisms, meaning males and females are separate entities, and sexual reproduction occurs within the host animal.
The life cycle of the kidney worm involves an intermediate host, typically an earthworm or a fish, which ingests the eggs passed by an infected animal through urine. The eggs then hatch in the digestive system of the intermediate host, allowing the larvae to migrate and develop inside its body. Eventually, the intermediate host may be ingested by another animal, such as a mammal or a bird, completing the parasite's life cycle.
The presence of kidney worms in the kidneys of an infected animal can lead to various health complications, including kidney damage, inflammation, hemorrhage, and in severe cases, urinary system dysfunction. Diagnosis of kidney worm infection is typically achieved through analysis of urine or by performing imaging procedures like ultrasound or radiography.
Preventive measures for kidney worm infection involve avoiding the consumption of undercooked or raw meat from infected animals and ensuring proper sanitation practices for both animals and their surroundings, reducing the risk of
The word "kidney worm" has a straightforward etymology. It is composed of two main parts:
1. Kidney: Referring to the organ within the human or animal body, known as the "kidney". The term "kidney" originated from the Old English word "cwiðeneȝe", which eventually evolved to "kidnei" in Middle English. The word likely derives from the Old English word "cwið", meaning "womb" or "womb-like", due to the kidney's shape.
2. Worm: This word refers to a variety of long, slender, soft-bodied creatures, often lacking legs or appendages. The term "worm" stems from the Old English word "wyrm", which is related to the Old High German word "wurm".
When combined, "kidney worm" simply refers to a worm-like parasite that infects the kidneys.
