The purpose of the present study was to help control AIS in Australia through a number of initiatives designed to improve capacity, and to acquire background information for use in more detailed future application of the techniques in the field. These procedures included provision of specialised diagnostic services, including development and evaluation of improved molecular means to identify the organisms, and to type individual strains that might be involved in particular flocks. An examination of in vitro drug sensitivities of Australian isolates of the organisms also was undertaken, to give a better understanding of what antimicrobial drugs might be effective for control. Finally, experiments were devised to examine the pathogenic potential of the organisms in adult birds, and to determine whether antimicrobials or enzyme addition to the diet might assist in control of AIS.
