INTRODUCTION
The
house fly, musca domestica, not only in a nuisance pest, but also acts as an important
mechanical vector for lots of pathogenic microorganism agents, including
bacteria, protozoa, worms, fungi and viruses amongst humans and animals. The
populations of house flies transmit the diseases agents by means of different
parts of their bodies’ chairs body, appendages and mouth parts) and secretions
(regurgitates and faces). House flies enter to the several places, including
contaminated premises because of their own biologic habits for feeding service

The habit of house fly favour the spread of bacteria and other diseases causing
organisms. www.idph.state1/us/enhealth/pefilthflies.html.
Consequently,
house fly for example, can spread diseases such as food poisoning and dysentery

More
than 100 percent associated with the house fly may cause disease in humans and
animals including typhoid, cholera bacillary dysentery, tuberculosis anthrax
ophthalma and infantile diahea, as well as parasitic protozoa and worms www.edis.lfas.ufl-edu/in503
pathogenic organism are picked up by flies from garbage, sewage and other
source of filth, and then transferred on their mouthparts and other body parts
through their vomits, faces and contaminated external body part to humans and
animal food. www.edis.lfas.ufl-edu/in503.
In
addition to classical pathogens, there are newly recorded bacterial which are
medical importance as the new findings macoveil and zurek L. ecology of

Houseflies
have long been regard as potential carries of microorganisms since pathogenic
microorganisms are widespread in the hospital environment there is abundant
opportunity for flies to become contaminated and in turn, to contaminant the
patient environment in the present study, an attempt was made to isolate and
identify pathogenic bacteria fungi and parasites from the house fly musca
domestica collected in the surgical hospital and also in a remote residential
area located 5km from the hospital. A total of 113 flies were collected 65 from
a surgical ward (test) and 48 from a residential area for comparison ten genera
of bacteria were isolated from the test group of flies compared with nine from
the control group in primary isolations it was observed that the load of
bacteria carried by the test group of flies was significantly more (p/ less
than 0.001) than for the control flies pseudomonia aerugnosa, enterococcus
faecalis and vividens strepthococci were isolated only from the test flies the
isolation rate of staphylococcus aurevs was significantly higher (p less than
0.001) in test housefly than in the control houseflies.
There
was no significant different in isolation of parasitic ova and custs from test
and control housefly candida spp were isolated in almost equal numbers from
both groups of houseflies yet none of these was Candida albicans houseflies
therefore may acts as vectors of potentially pathogenic bacteria in a hospital
environment have reported which houseflies in food handling and serving
facilities carry and may have the capacity to transfer antibiotic resistant and
potentially virulent bacteria. Meek www.pctonlune.com/arcticles/artical.as?id=1510&issueid=91
in the study founded by orikin pest control has described new nine transmitted
bacterial by houseflies. Three of them consisting, acinetobactor, baumanni that
has been linked to meaningitis, Bacillus pumilus, which can cause food
poisoning and enterobactor sakazaki which can cause urinary tract, pulmonary
and blood stream infections. Because M. domestica is capable of carrying a
variety of bacteria, viruses, fungi and parasites disease over its body’s
appendages, we can make some critical steps forward to fight against these
micro organisms basically, one of these step is to identify those pathogenic
agents and as a results promoting the status of society health. Service MW.
