Macaque the other monkey's mouth. Several species of macaque are used extensively in animal testing, particularly in the neuroscience of visual perception and the visual system. Nearly all (73–100%) pet and captive rhesus macaques are carriers of the herpes B virus. This virus is harmless to macaques, but infections of humans, while rare, are potentially fatal, a risk that makes macaques unsuitable as pets. Urban performing macaques also carried simian foamy virus, suggesting they could be involved in the species-to-species jump of similar retroviruses to humans. In Vietnam, macaque is eaten by some people as bushmeat. In January 2018, scientists in
Crab-eating macaque and "M. f. condorensis" is vulnerable. All other subspecies are listed as data deficient and need further study; although recent work is showing "M. f. aurea" and "M. f. karimondjawae" need increased protection. One concern for conservation is, in areas where "M. fascicularis" is not native, their populations need to be monitored and managed to reduce their impact on native flora and fauna. The genome of the crab-eating macaque has been sequenced. On 24 January 2018, scientists in China reported in the journal "Cell" the creation of two crab-eating macaque clones, named "Zhong Zhong and Hua Hua", using the complex
