New Leptospirosis Vaccine
2 June 2025
Leptospirosis is a potentially fatal bacterial disease which has reemerged in the Greater Sydney region in the last few years. We are not aware of any confirmed cases from the Blue Mountains. However it is spread primarily via infected rodents and contaminated water, so it has the potential to be found within our region. Leptospira bacteria can infect a wide range of hosts, including cats and dogs. In cats, it rarely causes illness. However, dogs can become severely ill. Signs of leptospirosis diagnosis in dogs can be quite vague and can include:
- Lethargy
- Loss of appetite
- Vomitting
- Abdominal Pain
- Diaherra
- Drinking or urinating more than usual
- Jaundice (yellowing of the skin and mucous membranes)
Severe infections can lead to kidney and/or liver failure and death.
Two strains have been confirmed to cause disease in dogs. However, only one strain is covered by the commonly used Protech C2i vaccination. A new vaccine, Nobivac Lepto 2, has recently been released on the market and covers both strains of Leptospirosis. This vaccine is now available at Selwood House Vets! As it is a new vaccination, any dog moving onto this vaccination will need two injections approximately 4 weeks apart.
No vaccination is 100%, so avoiding contact is still advised. Prevent your dog from swimming in or drinking stagnant water and avoid contact with rodents and farm animals where possible.
If you would like to add the Nobivac Lepto 2 vaccine to your dog's vaccination schedule, please give us a call on 02 4758 8990.
