Molecular Evolutionary Genetics Analysis version 6. First description of the horse stomach worm, Habronema muscae Spirurida: Infective L3-larvae that are deposited on the eyes cause so-called ocular, ophthalmic or conjunctival habronemiasis that can cause inflammation of the eye envelopes conjunctivitis and the eyelids. Predilection site of adult Habronema worms is the stomach.
After examination by light and scanning electron microscopy, Habronema muscae Carter, and H. Parasitic Nematodes from Equus spp. Large and Small Strongylesbut remain in the lumen, mainly in the mucus surrounding the wall, and do not feed primarily on blood but on other digestive or body fluids. So far no true vaccine is available against Habronema worms of horses.
In some countries feed-through larvicides mainly with cyromazine are approved for use on horses that can contribute to reduce the fly populations in sp; premises. These worms do not affect cattle, sheep, goats, pigs, dogs or cats. Very little is known regarding the immune response of horses to Habronema infections and whether significant levels of immunity can be acquired after repeated exposure.

Topics Discussed in This Paper. Infective L3-larvae can also infect the hosts if they swallow flies e. Molecular Evolutionary Genetics Analysis version 6. Othe species of the same family affect also birds, amphibians and reptiles. Larvae that do not reach the stomach but remain in the tissues e. These larvae are ingested by fly maggots that develop in the horse manure.
A key measure to reduce the risk of infection is adequate manure management to break the spp cycle of the worms, both nabronema and indoors, since flies can develop in horse droppings both on pasture as well as inside stables and barns. In case of massive infections they can cause gastritis, colic, and other digestive disorders that can result in weight loss. From This Paper Figures, tables, and topics from this paper.
Draschia megastoma can causes tumor-like swellings in the stomach wall that can burst and cause fatal peritonitis, but this is rather unusual. A, Anterior part, ventral view; B, Tip of male tail, ventral view; C, Tip of male tail, lateral view; D, Posterior extremity habrpnema female, lateral view.

Morphology of the spicules is species-specific, important for species determination. Occasionally, infected L3-larvae deposited on the nostrils can migrate into the lungs of the host and cause so-called pulmonary habronemiasis. habrobema
