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
Coimbra Filho's titi fragment of the population, limiting reproductive options. The species' natural geographical distribution also contributes a threat to the species. Coimbra Filho's titi only naturally occurs in the Atlantic coastal forests in northeastern Brazil. This is a relatively small area in the states of Sergipe and Bahia. Due to this small range, any disturbances to these areas pose a larger than normal threat to the species' survival. More than anything else, however, human interference is the source of many problems to Coimbra Filho's titi. The areas around and inside its habitat are being developed, including paving roads and the promotion of
