Paramphistomiasis
J. C. BEARDWOOD, B.V.Sc., Veterinary Inspector, Camden
Although this condition has been recognised for some years as pathogenic in Districts on or adjacent to the North Coast of New South Wales, it appears that little importance has been attached to this parasite (the Stomach Fluke) south of Sydney.
Probably due to adverse seasonal conditions, and the fact that cattle were not showing a satisfactory response to treatment for round-worm infestations, a greatly increased number of faecal samples were examined from the latter area during 1964.
The majority of samples were submitted by A. V. Medenis, V.M.D., a private practitioner at Gerringong; and consequently refer particularly to the Gerringong-Berry area. But other samples submitted included cattle on the Tablelands (Moss Vale-Bowral), and in the Castle Hill-Glenorie region.
Away from the Coast and Tablelands, infestations with paramphistomes were very light, but of samples from 84 separate properties on the Coast, mainly, and the Tablelands, 34 properties were positive for paramphistomes; with counts of at least 100 e.p.g. from 29 of the 54.
Where subsequent treatment on a herd basis was carried out there has been ample evidence of improved bodily condition and milk production.
