Titi monkey adenovirus Titi monkey adenovirus Titi monkey adenovirus (TMAdV) is an adenovirus first identified in a New World titi monkey of the genus "Callicebus", and the virus also infected to at least two humans. It is a large DNA-based virus which can cause death in monkeys, and respiratory illness has been recorded in humans. It was first discovered in Davis, California, at the California National Primate Research Center. The discovery of TMAdV was made by the laboratory of Charles Chiu and the UCSF-Abbott Viral Diagnostics and Discovery Center, using a DNA microarray test called the ViroChip that is able to detect all
White-eared titi species within the genus "Plecturocebus". Although the exact position of species within the genus "Plecturocebus" in the "P. donacophilus" group with the Rio Beni titi ("P. modestus"), Rio Mayo titi ("P. oenanthe"), Ollala brothers' titi ("P. olallae"), and white-coated titi ("P. pallescens"). The white-coated titi has sometimes been considered a subspecies of the white-eared titi, but they are treated as separate species in the latest edition of Mammal Species of the World. The white-eared titi is a medium-sized primate with grey to orange pelage. The species does not exhibit sexual dimorphism; the male's head and body length averages while females
