Are there any laboratory scientific studies on flies and what comes out of them when pressed into a drink?

The hadith "If a fly falls into the vessel of any of you, he should dip it completely..." is an authentic hadith. Some, both in the past and present, have found this hadith problematic, yet modern science has proven its medical miracle. It has been discovered that flies carry disease-causing germs, and also carry "phage" bacteria that attack and devour these germs. Therefore, a Muslim must believe everything that the Messenger of Allah, peace and blessings be upon him, brought.
