Seventeen cases of vulval myiasis in crossbred Jersey and Zebu cattle aged 3-10 years treated successfully with maggoticidal and manual manipulation has been studied and placed on record.
Myiasis is a common problem among domestic animals particularly during the warm months of the year. Myiasis/maggot wounds at different locations of animals body are problematic as they feed on the healthy as well as decaying tissue and delay the healing process of the wounds leading to secondary bacterial infection. So a study on the vulvar myiasis reported rarely in animals of Kashmir valley is placed on record.
The study was conducted on seventeen cases of crossbred Jersey and Zebu cattle aged 3-10 years brought for treatment with the history of vulval wound, rubbing vulva against inanimate objects, swinging of tail, reduction in milk yield and the animals were not responding to the treatment. Clinical examination revealed massive infestation of maggots with no suppuration but wound lesion of hemorrhagic nature with foul smelling discharge. The animals were restrained in Travis and the wound was thoroughly cleaned with Luke warm water. Dead and devitalized tissue as about to slough was removed avoiding further drainage of the underlying healthy tissues. Thereafter the excess water along with the blood oozing out in maggots were removed with forceps and turpentine gauze was applied in the wound to remove deeply burrowed maggots. The wound was antiseptically cleaned with mild Potassium Permagnate solution and tincture iodine followed by local application of Lorexane ointment (Gloxosmithkline, Mumbai). Injection ampicillin-cloxacillin @ 10 mg/kg BID I/M, Proxyvet- D S(Wockhardt ,Mumbai) @ 1ml/25kg body weight I/M and chloramphinicol maleate 7-10 ml I/M daily for five days was administered and regular dressing as above was carried out till complete healing of wound was observed. The animals recovered within 8-10 days successfully with no further reoccurrence.
Neglected wounds and warm months of the year irrespective of the site get infected with maggots and are a constant source of irritation to the animals. The commonly encountered maggots as detected from maggotized wounds in domestic animals are mostly the larvae of house fly viz.Musca domestica (Rehman and Nurruddin, 1982). Though vagina is freely dilatable and is less often injured, lacerations are more likely to occur near vulval border during stressful parturition, which attract the flies to feed on it and lay eggs which in turn lead to maggot wounds (Robert, 1983). A sero-sanguineous fluid expressed from the uterus and the maternal caruncles and delayed expulsion of uterine contents with foul small and such discharge generally attracts the flies to feed on it and lay eggs and in turn myiasis is produced. Even the scavenger birds like crows may also cause vulval injury and if unnoticed and neglected the wound may become maggoted with the feeding and subsequent laying of eggs by the musca species. Lorexane ointment applied to repel flies is obligatory to overcome such hazards. Strict asepsis contribute major share in success of any wound healing. Hence in the present case careful removal of the larvae and use of maggoticidal preparation and other ingredient of the ointment along with the systemic antibiotic therapy, use of anti-inflammatory analgesic and antihistaminic in this study had facilitated the early recovery of the animals; which are in corroboration with the results of Jana and Jana (2005).
