When a fly falls in the drink of one of you, he should fully dip it and then throw it away

Abu Huraira, may Allah be pleased with him, narrated:

This Hadith is a scientific miracle of the Messenger of Allah, may the peace and blessings of Allah be upon him,. He informed about what the science has proven by experience. He is not a scientist, may the peace and blessings of Allah be upon him, nor is he an expert on insects. He does not rely on observation, experimentation, as the scientists do for the safety of the premises and the validity of the results. Rather, He is a messenger sent by Allah to guide people, so that Allah provided him with knowledge and wisdom. Moreover Allah informed him about some of these wonders including some of the benefits and harms that result from dealing with this insect.

I have been looking at the scientific references on the harms of flies and its benefits out of believing in this Hadith.
Finally, I found a scientific research published in Al-Azhar, documented by evidence, written by two of the leading scientists in the field of medicine and the study of harmful and useful insects. 

In 1957, Moftis isolated antibiotic substances from the fungus farm found on the fly body. It was found to be potent in some gram-negative bacteria, such as typhoid bacteria, to resist germs that cause febrile diseases that require a short time of incubation. He found that one gram of these bio-toxic substances can sterilize more than (1000) liters of milk of contamination with the mentioned pathogenic bacteria. This is the largest evidence of the strong strength of the effect of these substances.
