STEPHANOFILARIASIS

Stephanofilariasis is skin disease at cow, goat, and buffalo that caused by worm genus of Stephanofilaria.

Habitat and host of Stephanofilaria :

1. Stephanofilaria dedoesi at skin of neck, dewlap, back, and around eye of the cow in the Sulawesi, Sumatra, and java.
2. Stephanofilaria kaeli at feet skin of cow and goat.
3. Stephanofilaria zaheeri at coat horn and earsore of buffalo in the India.
4. Stephanofilaria okinawaensis at mouth and nipple of the cow in the japan.

Cycle life of Stephanofilaria is indirectly need intermediate host from genus of fly, through mechanism the fly bite host and sucking secrete of vulnus, so that microfilaria that there is in vulnus will eaten by fly. Then, microfilaria will expanding became mature worm at layer of dermis and caused inflammation around skin. If the fly bite definitive host will attacked infection Stephanofilariasis. The fly as a vector of Stephanofilariasis are Musca conducens, Musca autumnalis, Musca planicep, Siphona exigua, Stomoxys calcitrans, Haematobia irritans, Lyperosia titilans, and Sarcophaga sp.

Mature worm of Stephanofilaria dedoesi can cause crusty dermatitis is cascado. Papulae that caused by mature worm will expanding and joining so that vulnus became big and closed by crustae. Predilection of parasite in epithel of skin can cause inflammation and proliferation rete malpighi so that occur damage of epithel cell, follicle of hair, and skin gland. Ulceration, hyperkeratosis, and alopecia can occur as a effect of damage folicle of hair. Injury that attack skin can contain microfilaria and mature worm, in this condition will easy occur secondary infection.

The clinic sign of Stephanofilariasis include can be known from injury in skin that be closed of crustae and appear thick. Early sign there are abnormality blister small, then joining became big injury. Stephanofilaria dedoesi cause injury usually at neck, dewlap, shoulder, around eye, and ear. Stephanofilaria kaeli cause injury at feet, and Stephanofilaria zaheeri cause bristle in the back and ear.

Diagnose of Stephanofilariasis :

1. Scraping of bristle rather into after crustae be opened so will be found microfilaria.
2. Isolation of mature worm using NaCl physiologis after animal be slaughtered. Skin that experience injury soon be taken, inserted into NaCl physiologis and incubation at 37 Celcius degree during 30’ - 60’, then can be found mature worm with using microscope.

Stephanofilariasis can be cured without treatment, but can cause damage of skin that decreasing value of sale. Treatment can be done by cleaning injury from crustae and tissue of necroses, then can be given balm such as Asuntol 2 %, Trichlorphon 10 %, Trichlorphon 8 %, Sumithion 4 %, and Coumaphos 2 %.
