Abstract: | Four species of Stephanofilaria have been reported from India causing various forms of dermatitis in cattle, buffalo, goat and elephant. However, additional work is needed to establish their identity as separate species. The lesions appear to flare up following reinfection, while the application of a petroleum jelly alone reduces them. In vitro tests have shown organophosphorous compounds to possess stephanofilaricidal action in addition to their insecticidal activity. Aspects where further work is needed are indicated. |
