Infections with nematodes of the genus GNATHOSTOMA, superfamily THELAZIOIDEA. Gnathostomiasis is a food-borne zoonosis caused by eating undercooked or raw fish or meat.

A genus of parasitic nematodes that occurs in mammals including man. Infection in humans is either by larvae penetrating the skin or by ingestion of uncooked fish.

Infections with nematodes of the order SPIRURIDA.

Skin diseases caused by ARTHROPODS; HELMINTHS; or other parasites.

The presence of parasites in food and food products. For the presence of bacteria, viruses, and fungi in food, FOOD MICROBIOLOGY is available.

Mild to severe infections of the eye and its adjacent structures (adnexa) by adult or larval protozoan or metazoan parasites.

Infections of the BRAIN; SPINAL CORD; or MENINGES caused by HELMINTHS (parasitic worms).

Immunoglobulins produced in a response to HELMINTH ANTIGENS.

A benzimidazole broad-spectrum anthelmintic structurally related to MEBENDAZOLE that is effective against many diseases. (From Martindale, The Extra Pharmacopoeia, 30th ed, p38)

Infections caused by nematode larvae which never develop into the adult stage and migrate through various body tissues. They commonly infect the skin, eyes, and viscera in man. Ancylostoma brasiliensis causes cutaneous larva migrans. Toxocara causes visceral larva migrans.

A mixture of mostly avermectin H2B1a (RN 71827-03-7) with some avermectin H2B1b (RN 70209-81-3), which are macrolides from STREPTOMYCES avermitilis. It binds glutamate-gated chloride channel to cause increased permeability and hyperpolarization of nerve and muscle cells. It also interacts with other CHLORIDE CHANNELS. It is a broad spectrum antiparasitic that is active against microfilariae of ONCHOCERCA VOLVULUS but not the adult form.

Substances used in the treatment or control of nematode infestations. They are used also in veterinary practice.

Abnormal increase of EOSINOPHILS in the blood, tissues or organs.

Aspects of health and disease related to travel.

Any part or derivative of a helminth that elicits an immune reaction. The most commonly seen helminth antigens are those of the schistosomes.

Agents destructive to parasitic worms. They are used therapeutically in the treatment of HELMINTHIASIS in man and animal.

Inflammation of the coverings of the brain and/or spinal cord, which consist of the PIA MATER; ARACHNOID; and DURA MATER. Infections (viral, bacterial, and fungal) are the most common causes of this condition, but subarachnoid hemorrhage (HEMORRHAGES, SUBARACHNOID), chemical irritation (chemical MENINGITIS), granulomatous conditions, neoplastic conditions (CARCINOMATOUS MENINGITIS), and other inflammatory conditions may produce this syndrome. (From Joynt, Clinical Neurology, 1994, Ch24, p6)

Infectious diseases that are novel in their outbreak ranges (geographic and host) or transmission mode.

A group of cold-blooded, aquatic vertebrates having gills, fins, a cartilaginous or bony endoskeleton, and elongated bodies covered with scales.

Water containing no significant amounts of salts, such as water from RIVERS and LAKES.

Immunologic method used for detecting or quantifying immunoreactive substances. The substance is identified by first immobilizing it by blotting onto a membrane and then tagging it with labeled antibodies.
