　　At the end of 2017, careful "Panda Powder" found the recent photos and live videos of "white eyes" of online celebrity giant pandas Qiyi, Qifu, Xiaoya and Yongyong in chengdu research base of giant panda on social media. From a photo published by Sichuan media, it can be clearly seen that the "dark circles" of this giant panda have obviously turned white and their hair has fallen off.

　　Chengdu research base of giant panda staff said in an interview with the media that Sichuan’s humid and humid environment is more conducive to bacterial reproduction than other dry areas, and some giant pandas are sensitive in constitution, so mite infection is very easy to occur. The infection caused by the suspected mites is not explosive, but sporadic and not contagious. Currently living in chengdu research base of giant panda, there are no more than 10 giant pandas with eye depilation.

　　Yang Guangyou told the reporter: "We have recently paid attention to three giant pandas with serious clinical symptoms ‘ Yongyong ’ 、‘ Qiyi ’ And ‘ Xiaoya ’ Anesthesia was performed, and skin samples around the eyes were scraped and sent to the parasitology laboratory of Sichuan Agricultural University for PCR detection of demodex, and the test results were negative. In order to further these ‘ Mite eye ’ The individual was diagnosed, and the base invited me to have a bedside examination. At present, the test is being repeated. Once the PCR is positive, the base will use the screened effective drugs for treatment. "

　　Yang Guangyou said: "According to my observation, the condition of the giant panda in the base is mild, because only the lesions appear around the eyes, and the spirit and appetite are normal, and there is no malnutrition or weight loss, but the giant panda is ‘ National treasure ’ , so the condition was artificially amplified. According to the symptoms and signs, at present, it can only be said that mite infection is suspected. These giant pandas were scraped off due to sampling, and some netizens thought that the hair loss was aggravated, which was actually caused by sampling. "

　　"Saving" the giant panda "Black Eyesocket" is in action.

　　How do these giant pandas suspected of being infected with mites recover? How long will it take to change back to "dark circles"? These two issues are the most concerned by netizens.

　　Yang Guangyou said that if it is diagnosed as mite infection, you don’t have to worry too much. It is just a very common skin disease, and domestic pets and humans have different degrees of infection. "acariasis is one of the common ectoparasitic diseases of giant pandas. The main pathogens are scabies, itchy mites and demodex. Its clinical symptoms are itching, scabbing, depilation and skin thickening. Ivermectin and Serratin have achieved good therapeutic effects on scabies and itch mites. The appearance of the giant panda at the base as claimed by netizens ‘ Mite eye ’ Veterinarians began to investigate the etiology and etiology more than a year ago, focusing on the detection of demodex, fungi and vitamins and trace elements, but the cause has not been identified. " Yang Guangyou said.

　　Yang Guangyou said that apart from parasitic infection, there are many reasons that lead to animal body depilation, such as lack of vitamins and trace elements. At present, experts are also looking for possible causes from these aspects, and finding the cause can be targeted for treatment.

　　Finally, Yang Guangyou said, "If it is diagnosed as mite infection, the base has screened out Isoxazoline (trade name BRAVECTOR, Afoxolaner, etc.) and MilbemycinOxime, and made safety tests. As long as the right medicine is given, the hair will grow back quickly after treatment. ‘ Dark circles ’ Come back, netizens don’t have to worry too much. "
