Abstract
Mange is a common and economically significant dermatological condition that affects pigs, leading to compromised animal welfare and reduced productivity. Sarcoptic mange is caused by Sarcoptes scabiei var. suis and Psoroptic mange, caused by Psoroptes spp. are individually well-documented in porcine hosts. However, concurrent infestation of both mite species in pigs has not been reported previously. The present investigation documents a rare case of simultaneous infestation with S. scabies var. suis and Psoroptes spp. in Large White Yorkshire pigs reared at a commercial pig farm in Punjab, India. Clinically, affected animals exhibited intense pruritus, alopecia, erythema, thickened scaly skin, crust formation, and reduced body condition. Skin scrapings and microscopic examination confirmed the presence of both Sarcoptic and Psoroptic mites based on their distinct morphological characteristics. This dual infestation poses significant health concerns, including severe irritation, poor growth performance, and an increased risk of secondary infections. Additionally, the zoonotic potential of sarcoptic mange highlights the occupational health risks for pig handlers. The affected pigs were topically treated with 1.25% deltamethrin. All pigs tested negative for mites upon parasitological examination, and a decrease in skin lesions was observed after 12 days of therapy.
