Attention dog owners! 🐾
We would like to give you an update and summary about canine leptospirosis cases seen in Sydney this year. No cases were identified in January. In February, two cases were identified – one in Waterloo and the other in Figtree near Wollongong. The dog from Waterloo was euthanised due to kidney failure. We were unable to identify the causative strain (serovar) in this dog as the dog died so quickly that it did not have time to develop an antibody response. The dog from Figtree presented for kidney failure and was intensively treated at another specialist hospital. Sadly, the dog died due to complications. In this case the causative strain is likely a strain called serovar Australis which is different to the strains identified last year (Copenhageni, Hardjo).
We recommend vaccination in dogs living within a 5km radius of Surry Hills, in Annandale, Balmain, Newtown, Paddington, Crows Nest or its immediately surrounding suburbs or if your dog is in contact with rats. Please discourage your dog from having any contact with rats and don’t let your dog drink out of puddles or other stagnant water sources. The vaccine needs to be given twice, 2-4 weeks apart and yearly thereafter.
What is Leptospirosis?
Leptospirosis is a potentially fatal bacterial infection that can cause acute kidney failure and liver disease in dogs. Dogs become infected by contact with urine from rats or indirectly via contaminated water or soil. They can also become infected by hunting and eating rats. Prevention of leptospirosis is achieved by limiting contact to sources of infection and vaccination. Until recently clinical leptospirosis has only rarely been reported in Sydney and therefore, historically, dogs have not been routinely vaccinated against this disease. Clinical signs can initially be very vague such as lethargy, vomiting and diarrhea. Importantly, leptospirosis is a zoonotic disease which means that humans can become infected as well, for example through contact with rat urine or urine of infected dogs, through skin wounds or through the mucus membranes (eg in the mouth).
