Do bats have discovered a new flu virus


02/03/2012

Scientists have discovered that herbivorous bats that live in Guatemala, a new type of influenza A virus subtypes other kindred, and called it the H17, as reported by the scientific journal Nature News.

Details of this discovery experts from the Center for Prevention and Control of viral diseases United States (CDC) described vrabote, published in the Proceedings of the National Academy of Sciences.

According to information from the authors of the study, the virus H17 evolved from a common ancestor long ago all flu viruses and practically does not represent an immediate threat to human health. However, the similar characteristics of the virus to other subtypes suggests interchange between genetic information.

Ruben Donis (Ruben Donis), a molecular virologist and head of immunization at the CDC and colleagues identified H17 virus in three species of bats (Sturnira lilium) or zheltoplechih listonosov belonging to the subfamily listonosov herbivores. Total researchers have studied 316 bats belonging to 21 species and living in Guatemala.

In order to detect new viruses, experts were engaged a few years ago, the development of specific molecular probes for performing polymerase chain reaction - the experimental method used in molecular biology. With the help of such probes in 2010, scientists were able to identify the bat rabies virus.

It should be noted that the bats in recent times are often subject of research in virology in the fact that besides the rabies virus were found in animals viral diseases such as Ebola, SARS (SARS), and Nipah virus.

It is still unclear exactly how the bats spread of a new type of influenza virus, but because the greatest amount of virus was found in the gastrointestinal tract of animals, the researchers suggest that the infection is transmitted by fecal-oral method.

Currently, CDC scientists are exploring the geographical distribution of the latter-day influenza virus in bats that live all over South America, Africa and Asia, to determine whether these animals are a natural focus of massive outbreaks of infectious disease in humans.
