1-The Prophet's Sayings:
Prophet Muhammad, peace be upon him, made a remarkable statement about the flies carrying antidotes:
Narrated Abu Huraira:"Allah's Apostle said, "If a fly falls in the vessel of any of you, let him dip all of it (into the vessel) and then throw it away,for in one of its wings there is a disease and in the other there is healing(antidote for it) i e. the treatment for that disease."(Translation of Sahih Bukhari, Volume 7, Book 71, Number 673)"
Narrated Abu Huraira:"The Prophet said "If a house fly falls in the drink of anyone of you, he should dip it (in the drink),for one of its wings has a disease and the other has the cure for the disease."(Translation of Sahih Bukhari, Volume 4, Book 54, Number 537)"

The surface of flies is the last place you would expect to find antibiotics,yet that is exactly where a team of Australian researchers is concentrating their efforts.
Working on the theory that flies must have remarkable antimicrobial defences to survive rotting dung, meat and fruit,the team at the Department of Biological Sciences, Macquarie University,set out to identify those antibacterial properties manifesting at different stages of a fly's development.
"Our research is a small part of a global research effort for new antibiotics, but we are looking where we believe no-one has looked before," said Ms Joanne Clarke, who presented the group's findings at the Australian Society for Microbiology Conferencein Melbourne this week.The project is part of her PhD thesis.
The scientists tested four different species of fly: a house fly, a sheep blowfly, a vinegar fruit fly and the control, a Queensland fruit fly which lays its eggs in fresh fruit. These larvae do not need as much antibacterial compound because they do not come into contact with as much bacteria.
Flies go through the life stages of larvae and pupae before becoming adults. In the pupae stage, the fly is encased in a protective casing and does not feed. "We predicted they would not produce many antibiotics," said Ms Clarke.
They did not.However the larvae all showed antibacterial properties(except that of the Queensland fruit fly control).
As did all the adult fly species, including the Queensland fruit fly (which at this point requires antibacterial protection because it has contact with other flies and is mobile).
Such properties were present on the fly surface in all four species, although antibacterial properties occur in the gut as well. "You find activity in both places," said Ms Clarke.
"The reason we concentrated on the surface is because it is a simpler extraction."
The antibiotic material is extracted by drowning the flies in ethanol, then running the mixture through a filter to obtain the crude extract.
When this was placed in a solution with various bacteria including E.coli, Golden Staph, Candida (a yeast) and a common hospital pathogen, antibiotic action was observed every time.
"We are now trying to identify the specific antibacterial compounds,"said Ms Clarke. Ultimately these will be chemically synthesised.
Because the compounds are not from bacteria, any genes conferring resistance to them may not be as easily transferred into pathogens. It is hoped this new form of antibiotics will have a longer effective therapeutic life.

Antibacterial actionof Myiasis-causing flies.
Erdmann GR.
Department of Pharmacy Practice, College of Pharmacy,University of Minnesota, Minneapolis, MN 55455, USA.
Some species of calliphorid blowflies lay their eggs in wounds; their larvae develop by feeding on the tissue, and the infection is known as myiasis or fly-strike. But wounds, from whatever cause, are frequently contaminated with bacteria - many o f which can spread in the bloodstream causing septicaemia and/or toxaemia. For example, wound contamination with Clostridium welchii - leading to 'gas gangrene' - was a frequent cause of death amongst battlefield casualties. It is from such situations that early observations were made on the beneficial effect of some blowfly larvae in limiting the bacterial infection of wounds.Indeed, some military surgeons would deliberately infest wounds with blowfly maggots in order to prevent bacterial complications.Now, a century or two later, the search for new antibiotics had led researchers back to these early observations, and in this article, Gory Erdmann describes progress in understanding the antibacterial action of blowfly maggots.

Abstract
The male fruitfly,Drosophila melanogaster, transfers to his mate proteins that increase his reproductive success by causing changes in her behavior and physiology.Here we show that among the transferred proteins are ones with antibacterial activity.We performedEscherichia colioverlay assays of native PAGE or renatured SDS朠AGE of reproductive tissue extracts of wild-type or transgenic males deficient in accessory gland function. We detected a 28 kDa male accessory gland-derived protein and two ejaculatory duct-derived proteins all with antibacterial activity. Based on its gel mobility and tissue of synthesis, one of the ejaculatory duct proteins is likely to be andropin, a previously-reported 6 kDa antibacterial peptide. All three proteins are transferred to females during mating. Therefore, they could assist in protecting the male's reproductive tractand, after transfer to the female, the female's reproductive tract or eggs against bacterial infection.Since seminal fluid proteins are transferred before the sperm, these antibacterial proteins may also protect sperm from bacterial infection.

okay, good. This should answer truthman2012's thread on the same hadith. There is always wisdom behind every authentic statement of the prophet(SAW). https://www.nairaland.com/2313630/islamic-medical-science-wrong-science
