Things To Know About Dog Roundworm Disease

Toxocaraasis (Toxocariasis) is caused by Toxocara canis or Toxocara cati, which is a species of roundworm called dog and cat roundworm. When the larvae of this worm cause damage to the human body, when they penetrate inside the organs such as lungs, liver, central nervous system, eyes ...
This dog roundworm larvae when laying eggs, eggs will follow feces into the environment and after about 1-2 weeks this egg will turn into embryos (this stage can cause disease if humans swallow worm eggs), The larvae then travel through the intestinal wall and travel through the bloodstream to the liver, lungs and central nervous system (where the larvae survive for months and afterward

. it will be destroyed by the body's inflammatory response or stop them from growing).
The extent of injury to the body along with the symptoms will depend on the number of larvae and the organs they invade.
Clinical forms of dog roundworm and cats
Visceral larva migrates (VLM), mainly in children under 5 years old with symptoms: fever, splenomegaly, respiratory symptoms similar to asthma, lymphocyte eosinophilia increased (the percentage may be up to 70%), hepatomegaly and necrosis, strabismus immunoglobulin IgM, IgG and IgE all increased In addition, you may also experience myocarditis, kidney inflammation, central nervous system damage
Ocular larva migrans (OLM), these cases are usually seen in children aged 5 to 10 years and are accompanied by symptoms of vision in one eye, sometimes with a cross-eyed eye. The amount of vision loss will be more or less depending on the area of injury (macula, retina).

The diagnosis of dog roundworm disease is a difficult task
Clinical symptoms of dog and cat roundworm disease are not specific to this disease. The larvae can spread freely throughout the body and will not always detect larvae.
Serum that is diagnosed with ELISA will use excretory antigen TES (Toxocara excretory - secretory antigen) which can cause cross-positive with other cases of worms, tapeworm infection (hookworm, eel worm, roundworm, liver fluke , tapeworm, lymphatic filariasis). There are also many places that produce ELISA kits with different antibody titres or optical density (OD) of positive thresholds, so it will be difficult to compare or monitor the course of the disease.
The presence of Toxocara antibodies does not indicate whether or not you have the disease because anti-toxocara antibodies can exist for more than 2 years, with ELISA and Western-Blot techniques to more than 5 years
The number of eosinophils may also be normal or increase but with very variable levels.
