Objective: To assess knowledge, attitudes and practices in relation to zoonoses among pet owners. Methods: Questionnaire completed by 81 clients attending a small animal practice in Sydney, Australia. Results: Most (64.5%) clients reported that they were not concerned about contracting a disease from their pet, but 7.9% and 3.9% of clients were a little or very concerned, respectively; 23.7% of clients stated that they had not considered the possibility. Although respondents indicated that they had heard of a number of zoonoses, knowledge of animal sources and exposure pathways was generally low, particularly for the more important zoonoses in Australia such as toxoplasmosis, psittacosis and Q fever. Only 37.0%, 12.3% and 11.1%, respectively, of clients had heard of these diseases. Most respondents (84.1%) indicated that they viewed veterinarians as having the primary responsibility for providing information about zoonoses, yet less than half (48.1%) recalled ever getting information from their veterinarian. Likewise, many respondents (48.1%) indicated that medical professionals played a role in providing information about zoonoses, yet less than one-quarter (23.5%) recalled ever getting information from their doctor. Conclusion: The low level of knowledge among pet owners about sources and exposure pathways indicates a need to strengthen communication between veterinarians, doctors and their clients around the possible risks of zoonoses and appropriate prevention strategies.

Brucella suis is an emerging, zoonotic disease predominantly affecting dogs and humans that engage in feral pig hunting in Australia and other countries. Although B. suis infection in dogs shares some clinical similarities to the host‐adapted species (B. canis), B. suis remains an incompletely understood pathogen in dogs with limited published data on its pathogenesis and clinical features. This case series describes the presentations, diagnosis, and clinical management of B. suis infection in three dogs: (1) a bitch with dystocia, abortion and mastitis; (2) an entire male dog with septic arthritis and presumptive osteomyelitis; and (3) a castrated male dog with lymphadenitis. Unique features of these cases are reported including the first documented detection of B. suis from milk and isolation from lymph nodes of canine patients, as well as the follow‐up of pups born to a B. suis‐infected bitch. Consistent with previous reports, all three dogs showed a favourable clinical response to combination antibiotic therapy with rifampicin and doxycycline. Individually tailored drug regimens were required based on the clinical presentation and other factors, including owner expectations and compliance with therapy as well as a zoonotic risk assessment (generally considered low, except around time of whelping). The authors include their recommendations for the clinical management of dogs that are at‐risk or seropositive for B. suis with or without clinical signs or laboratory‐confirmed infection.

Background Brucellosis caused by Brucella suis is a notifiable disease that has recently emerged in dogs in New South Wales ( NSW). Given the potential for zoonotic transmission, euthanasia of affected dogs is recommended, but this action is not mandatory. We report the clinical management of three dogs that underwent treatment at their owners' request. Case reports A 14-month-old spayed female crossbreed originally obtained from an urban animal shelter underwent extensive investigations in 2011-12 for lameness and back pain, culminating in decompressive laminectomy. Diagnosis of multifocal discospondylitis and spinal empyema was made, with B. suis cultured from surgical biopsy specimens. The dog responded to long-term treatment using rifampicin and doxycycline. A second case of B. suis infection was diagnosed in January 2016 in a 3-year-old crossbreed pig-hunting dog with unilateral testicular enlargement. Following serological diagnosis the dog was given preliminary therapy using rifampicin and doxycycline, the affected testis was resected and the patient given a further month of combination therapy. In March 2016 a 7-year-old crossbreed pig-hunting dog with brucellosis was handled similarly, although both testes were removed. Conclusion Brucellosis should be considered in the differential diagnosis of back pain, discospondylitis, lameness, abortion, prostatic abscessation and testicular/epididymal enlargement in dogs, especially if there is exposure to feral pigs or consumption of uncooked feral pig meat. Euthanasia is the only guarantee of reducing the public health risk to zero. However, where treatment is desired by the owner, combination therapy using rifampicin and doxycycline appears to be effective, when combined with surgical resection of infected tissues. Further monitoring of dogs during and after treatment is required to document cure. [ABSTRACT FROM AUTHOR]
