Abstract:

Some general properties of Octosporea muscaedomesticae spores that bear upon their ability to withstand extra-corporeal stressors were investigated. It was demonstrated that spores can tolerate ph 2.5 to 9.6 in an aqueous medium withstand high X-irradiations 6000 and 10,000R with little effect on their infectivity be deactivated by ultraviolet irradiation within 60 minutes in an aqueous medium withstand the effects of high temperature 65C for at least two hours in a clear aqueous medium held at 5C retain their infectivity for at least two years held in host tissues at -20C remain infective for at least six months at room conditions spores are viable for only eight months. It was also demonstrated that some spores do not germinate during their first passage through the alimentary tract of a fly. By selection based upon death time of the host, it was demonstrated that a strain of O. muscaedomesticae with increased fly-killing powers can be developed. Modified author abstract
