Roundworms

The most important roundworms in this region are:

• Scour worms

o Black scour worm Trichostrongylus vitrinus/ Trichostrongylus colubriformis
o Small brown stomach worm Teladorsagia (Ostertagia) circumcincta
o Thin-necked intestinal worm Nematodirus species

In specific areas in some or most years: the west coast of Victoria, some of the south-western edges of the state including up the border to Edenhope, coastal areas of East Gippsland, irrigation areas such as the Goulburn Valley and Pyramid Hill and extending further into the state in particularly wet years:

• Barber’s pole worm Haemonchus contortus

Very wet years generally cause higher burdens of all worms. These can be fatal without scouring occurring.

Liver fluke

Liver fluke is an internal parasite that occurs in parts of this region depending on the distribution of the intermediate host snail. It can cause deaths from acute infections of immature fluke and Black disease from October to January, or anaemia and ill-thrift from chronic infections (generally January–June).

The life cycle differs from the simple lifecycle of roundworms, so control strategies are different.
This program relates to roundworms. To control liver fluke, see Liver fluke control.
