Humans may have propagate a respiratory infection to a group of rarified passel gorillas , causing an outbreak that killed at least one of the animals , researchers report .
The creation ’s population of mountain gorilla , about 786 of them , live in parks in Rwanda , Uganda and Democratic Republic of Congo , where they have become democratic attracter for tourist . Theecotourismindustry built up around them generates revenue to sustain the species and enhance awareness of the animals ' precarious status , according to a radical of investigator led by Gustavo Palacios of Columbia University in New York .

On July 4 , she was found deadened . The babe gorilla was born to a sick female parent on July 20 and died three Clarence Day later .
When their bodies were examined , traces of the human metapneumovirus were found in their tissues . Among humans , this computer virus can make severerespiratory infectionsand it has infected and killed chimpanzee .
While the female gorilla appeared to have been killed by a junior-grade , bacterial transmission enable by the virus , the babe ’s death seem forthwith relate to starving and an umbilical transmission that had spread to his kidney , harmonize to the researchers . The source of the computer virus remains nameless .
