A diagnostic and geographic analysis of liver fluke in South Eastern Australia

Liver fluke (Fasciola hepatica) are a parasite of many species including cattle, sheep, goats, alpacas and horses, as well as humans and wild animals. Liver fluke occurs in regions with aquatic environments, shallow and slow moving streams, dam overflows, springs and areas of slow seepage. Fluke require a suitable habitat for the primary intermediate snail host (Austropeplea tomentosa) and conditions suitable for the free-swimming larval stage. Snails are limited to higher rainfall (>600mm/year) areas of NSW (eastern), south eastern Queensland, Victoria, Tasmania and south eastern South Australia and irrigation areas. Awareness of the geographical distribution of liver fluke enables better management of the disease, highlighting ‘hot’ spots in Australia. Analysis of laboratory submission data with a digital spatial software program allows visual analysis, integrating data with maps. Monitoring of liver fluke is conducted predominately by fluke egg counts or to a lesser extent with more recently developed technologies such as Elisa-antibody or copro-antigens. Our diagnostic laboratory has conducted liver fluke egg counts (LFECs) for more than 25 years and with the development of an electronic database in 1998 a large and valuable data set has developed. To date, there are over 4,000 submissions for liver fluke testing on the database, allowing analysis of geographical distribution of liver fluke, potential resistance to treatment and changes over time related to increased awareness/education of potential production loss. Geographical Information Systems (GIS) software such as ArcGIS allow visualisation and analysis of geographically registered data (ie data accompanied by location coordinates). This presentation will summarise our findings from detailed analysis of the laboratory database.
