AFRICA- Four workers at pigs farms in the Philippines have contracted have contracted the Ebola-Reston, which is virus disease in non-human primate subtype of Ebola virus, in addition to a case reported two weeks ago. The health authorities conducted a test on the farmer acquaintances to see wheatear human to human infection occurred.

In this study by Hana M.Weingartl, from University of Manitoba Canada published in Scientific Reports on 15 November 2012 prove the evidence that infected pigs can efficiently transmit Zaire-EBOV (ZEBOV) commonly known as one of six known species within the genus Ebola virus to non-human primates in conditions resembling farm settings. The transmission of the virus occurred through air, since farmers infected were not involved in slaughtering or had no known contact with contaminated pig tissues.

In the research, were four macaques had an adjustment in animal facility at Africa for two weeks, and housed in the same room for one week prior to the swine injection. The macaques were housed in two levels of individual cages inside the pig pen, and separated from the piglets by wire barrier in front of the cages to prevent direct contact between the two species.

After that, the virus separation process is through swine digestion had to be however carried over onto replica plates for three passages prior to reading the cytopathic effect which is structural changes in cells that are caused by virus attacked.

Besides, the air sampling process started after analyse process by using BioCapture which is microorganism collected software, done at the same time to non-human primates sampling, later in the morning before noon. The air sampler device collects particles by bubbling the air through a pre-loaded buffer. This solution is not optimum for recovery of live surround viruses, and virus separation attempts were unsuccessful.

The result of this experiment raise a possibility that wild or domestic pigs may be a natural host for EBOV participating in the EBOV transmission to other species in sub- Saharan Africa.
