They do not penetrate through or into the stomach wall as other parasitic worms do e. A, 75 lm; B, 50 lm; C, D, 25 lm; E, sop From This Paper Figures, tables, and topics from this paper. 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. These larvae are ingested by fly maggots that develop in the horse manure.

Such infected wounds are difficult to heal, can become infected with secondary bacteria and may attract other fly species that can cause myiasis e. They all occur worldwide, but prevalence and incidence vary a lot depending on the region and the climatic conditions.

In case of massive infections they can cause gastritis, colic, and other digestive disorders that can result in weight loss. Occasionally, infected L3-larvae deposited on the nostrils can migrate into the lungs of the host and cause so-called pulmonary habronemiasis. After examination by light and scanning electron microscopy, Habronema muscae Carter, and H. These worms do not affect cattle, sheep, goats, pigs, dogs or cats.

Habronematidaea parasite of the horse Soraya Naem Parasitology Habrknema FilipskiSudhir Kumar Since occurrence of the flies is seasonal and depends strongly on climatic conditions temperature, humidity, etc. Since habronemiasis is caused by an allergic reaction of the host tissues to the worms, besides administration of an anthelmintic additional medication may be considered e.

Phylogenetic relationships of Habronema microstoma and Habronema muscae Spirurida: Habronematidaea parasite of the horse Soraya Naem Parasitology Research The prepatent period time between infection and first eggs shed is hbaronema two months, suggesting that more than one generation can follow during a habrronema season in regions with a warm and humid climate.


In some countries feed-through larvicides mainly with cyromazine are approved for use on horses that can contribute to reduce the fly populations in animal premises.

Small, hazelnut-like nodules can appear around the bronchi. Morphology of the spicules is species-specific, important habromema species determination. Topics Discussed in This Paper. They are often deposited on humid parts of the host’s body eyes, nose, lips, genitalia, open wounds, etc.

Affected horses may show chronic cough, difficult breathing and reduced performance. A key measure to habroneema the risk of infection is adequate manure management to break the life cycle of the worms, both outdoors and indoors, since flies can develop in horse droppings both on pasture as well as inside stables and barns. Habronematidae by scanning electron microscopy Soraya Naem Parasitology Research Regular manure removal ideally daily, at least weekly in stables and barns can significantly reduce the fly populations, provided that manure heaps elsewhere are adequately handled for preventing fly development keep it dry, promote maggot predators, etc.

They also have a nervous system but no excretory organs and no circulatory systemi. Habronema microstoma and Draschia megastoma are viviparous, i.
