The 5th magazine at-Tawheed in Egypt of 1397 AH / 1977 AD has published the results of the research of Dr.Amin Rida (a bone surgeon at the University of Alexandria), which explains that modern science finds that at one and the same time flies carry the germs that cause disease , and also carry the bacteria "Faaj" against these germs. Bacteria "Faaj" means a predator or pounce on germs.
