Rabies in an imported dog, Ontario, Canada, 2022.

Importation of rabies-infected dogs results in significant and costly public and animal health risks. In January 2022, a dog in Ontario, Canada, which was imported from Iran in June 2021, developed rabies, leading to an extensive public health investigation and administration of rabies post-exposure prophylaxis to 37 individuals. The dog was infected with a rabies virus variant known to circulate in Iran. This is the second reported case of a rabies-infected dog imported into Canada in 2021 from a high-risk country for canine mediated rabies. This case emphasizes the need for public education regarding the risks associated with importing dogs from high-risk countries for canine-mediated rabies and the benefits of establishing a public health team specializing in rabies exposure investigations.

Rabies in an imported dog, Ontario, 2021.

In July 2021, a dog was imported into Canada from Iran and subsequently developed clinical signs of rabies within 11 days of arrival. Following laboratory confirmation of the diagnosis of rabies, local, provincial and federal inter-agency collaboration was required to complete contact tracing to identify all persons and domestic animals that may have been exposed to the rabid dog during the potential virus shedding period. This case highlights the risks of importing animals from known canine rabies-endemic areas, identifies gaps in current dog importation policies that pose potential risk to human and animal health and prompts ongoing vigilance for this deadly disease among human and animal health partners, as well as members of the public who adopt imported dogs.

The first Linguatula serrata case in an imported dog in Finland.

Linguatula serrata is a pentastomid parasite infecting carnivores as definitive hosts and herbivores as intermediate hosts. In carnivores, including dogs, it usually parasitises the nasal cavity and sinuses, causing upper respiratory signs. This case report presents the first canine Linguatula case in Finland in an imported dog originating from Spain. In addition to the unremarkable clinical history of the dog, the treatment, parasite's morphology and molecular analysis are described, and the zoonotic potential is discussed.

Dermatobia hominis in a dog imported from Brazil to Romania.

BACKGROUND: Dermatobia hominis (Diptera: Oestridae: Cuterebrinae) is a parasite with an important zoonotic and economical impact in the cattle industry, distributed in Central and South America, inhabiting wooded areas along rivers and lowlands. It infests mammals including humans. Lately, there has been a growing trend for people to travel on holidays with their pet dog and also international trade of dogs has increased significantly in the last two decades. Hence, the risk of importation of exotic parasites, including agents of myiasis has increased. Dermatobia hominis has been commonly reported as an imported parasite to various countries, mostly as human cases and currently there are only two published cases of D. hominis imported with dogs to Europe. Herein, we report a case of D. hominis infestation in Romania in a dog recently imported from Brazil. METHODS: Larvae were manually extracted from nodules of a 4-month old non-neutered male, Fila Brasileiro in Arad, Romania. The larvae were morphologically identified, and one specimen was characterized molecularly by amplification and sequencing of a fragment of the mitochondrial cytochrome c oxidase subunit 1 gene (cox1). RESULTS: All larvae were morphologically identified as L3 of Dermatobia hominis. The BLAST analysis revealed a 98.81% nucleotide similarity to two D. hominis isolates from Brazil. The sequence was deposited in the GenBank database under the accession number MT364820. CONCLUSIONS: The travel history of dogs is an important part of the veterinary anamnesis questions and should be thoroughly conducted in the daily practice. Also, prior to and after the importation of dogs from tropical regions, a thorough check of the body surface to detect the presence of nodules is recommended.
