Most people do not know about this little worm. It has a strange and difficult name and an equally strange life-cycle. Normal deworming remedies do not kill this parasite and most people do not even know when their dog is infected with it. This article will try and shed some light on the how, what and where of Spirocerca lupi.

Spirocerca lupi is a roundworm. It is red in colour and 40 – 70 mm long. The eggs contain the larvae and have the shape of a paperclip. The eggs and larvae are passed from one host to another and this process normally starts when an animal passes the eggs in its stools. For example, a dung beetle ingests the eggs while working with or rolling in infected stools. The larvae then hatch inside the dung beetle and develop into more mature forms. A bird, lizard or another small animal might eat the dung beetle and then become infected with the larvae. Your dog will then become infected by eating the bird or lizard, called an intermediate host. This disease has not yet been seen in cats.

Living in a warm and sunny country is great, but with it comes all the parasites and diseases associated with a warm and/or tropical climate. One of these little scourges can be found nearly all over South Africa, namely ticks. Most people have at some or other time encountered a tick on their pet. This can be quite distressing – especially if you consider a disease like biliary (tick fever).
