Infection with the kidney worm dioctophyma renale is only found in southern Europe, Asia and North America and is also rare in cats there, the main host being mink. The kidney worm is the largest parasitic nematode with a length of up to one meter and shows a twofold host change: first intermediate hosts are Oligochaeta, second freshwater fish ...
Toxocara cati, also known as the feline roundworm, is a parasite of cats and other felids. It is one of the most common nematodes of cats, infecting both wild and domestic felids worldwide. Adult worms are localised in the gut of the host. In adult cats, the infection – which is called toxocariasis – is usually asymptomatic. However ...
Like many other worms, the female worm is larger than the male. Also, the females are more difficult to distinguish because the teeth sizes appear very similar among the various species of Ancylostoma. Male worms, however, have two broad lateral lobes and a smaller dorsal lobe with rays on the copulatory bursa.
[2] [14] [15] Located deep in the buccal cavity are eight to 10 teeth that are not thought to be used for attachment. [1] The adult male is about half the length of the female. Case reports have found male worms ranging from 3–6.3 mm in length and 360-380 μm in width. The larger females were reported to be 8.7-23.5 mm long and 550-570 μm wide.
Toxascaris leonina is a common parasitic roundworm found in dogs, cats, foxes, and related host species. T. leonina is an ascarid nematode , a worldwide distributed helminth parasite which is in a division of eukaryotic parasites that, unlike external parasites such as lice and fleas , live inside their host.

A. duodenale worms are pale grey or slightly pink. The head is bent a little in relation to the rest of the body, forming a hook shape – hence the name. The hook is at the front end of the body. They have well-developed mouths with two pairs of teeth. Males measure approximately 10 by 0.5 mm, and females are often longer and stouter.
Whole blood with microfilaria worm, giemsa stain. L. loa worms have a simple structure consisting of a head (which lacks lips), a body, and a blunt tail. The outer body of the worm is composed of a cuticle with three main layers made up of collagen and other compounds which aid in protecting the nematodes while they are inside the digestive system of their host.
The mouth has either three or six lips, which often bear a series of teeth on their inner edges. An adhesive 'caudal gland' is often found at the tip of the tail. [44] The epidermis is either a syncytium or a single layer of cells, and is covered by a thick collagenous cuticle. The cuticle is often of a complex structure and may have two or ...
