Rattles |
| Rhodococcus equi or “rattles” is one of the most important causes of pneumonia in foals aged 1 to 6 months, with most foals showing clinical signs before the age of 4 months. It can be treated successfully, the severity of the negative impact upon future athletic performance of affected foals remains controversial.
"Rattles" is the term used to describe what is usually a lung infection in foals aged between three and six months. It is caused by a bacteria, Rhodococcus equi, which is notable for the fact that it does not cause infections in yearlings or older horses, only foals aged between three and six months. The disease is very common in some regions of Australia, probably because it is widespread in the environment, including the soil. The disease can affect a number of body systems but most commonly causes a pneumonia, with the foals exhibiting a cough, hence the name "the rattles". Foals with the disease become lethargic and depressed and the mare will often show a distended udder because the foals stop sucking. Once the disease becomes well established, it is difficult to treat effectively . |
