Leptospirosis - more than a case of the flu

You may be wondering, why is leptospirosis common in vets? The reason is they visit multiple properties with cattle, sheep, goats or pigs, some of which may have leptospirosis, and their occupation exposes them to the leptospira bacteria, which is found in an infected animal's urine or aborted foetal materials. Artificial insemination technicians, abattoir workers, livestock handlers, and pig hunters are at a similar risk.

In livestock, leptospirosis may cause abortion, mastitis, blood in urine due to kidney damage, and fever and death in young animals. If the infection is well established in a herd, there may be little outward sign of disease. Leptospirosis can be readily diagnosed with a blood test. Many livestock producers, particularly dairy farmers, have leptospirosis control programs in place primarily to protect their staff.

Leptospirosis can be controlled through a vaccination program using 7-in-1, which includes protection against clostridial diseases found in a 5-in-1 vaccine, or by a standalone leptospira vaccine.

As with other vaccination programs, vaccination should be carried out by an initial vaccination, followed by a second four to six weeks later, and from then on, annually.

Rodent control is also an important component of leptospirosis control since rodents may carry and spread the leptospira bacteria.

If you ever suffer flu-like symptoms and are in one of the high-risk groups, it is worth discussing the possibility of leptospirosis with your doctor.

For further advice please contact your local veterinarian or Agriculture Victoria veterinary or animal health officer, or in NSW your Local Land Service.
