Hypopigmentation in mantled howler monkeys (gray 1849): First documented cases of whole-body leucism in South America.

The existence of hypopigmentation like leucism is the result of genetic anomalies that might be enhanced by external factors such as pollution. This anomaly may reduce survival rates. Leucism has been recorded in wildlife, but overall, it is considered very rare.

First description of sarcoptic mange in a wild coati (Nasua narica), in Ecuador, and cooccurrence of canine distemper virus.

We present a case of Sarcoptes and canine distemper virus (CDV) infection in a white-nosed coati (Nasua narica) that was trapped in the dry tropical forest of Cerro Blanco reserve, located in the coastal region of Ecuador. Sarcoptic mange is a highly contagious and zoonotic disease with worldwide distribution that causes epidemics. Mange is produced by Sarcoptes mites that causes severe epidermal damage.
