Muscoid-Fly Octosporeosis.
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)
