Babesia canis and tick-borne encephalitis virus (TBEV) co-infection in a sled dog
Journal Title: Annals of Agricultural and Environmental Medicine - Year 2013, Vol 20, Issue 3
Abstract
[b]Introduction and objectives.[/b] Sporting dogs, including sled dogs, are particularly prone to tick-borne infection either due to training/racing in forest areas or through visits to endemic areas. The aim was to present tick-borne infections in a 6-dog racing team after a race in Estonia. [b]Materials and methods.[/b] On the 4th day after return to Poland, the first dog presented with babesiosis symptoms and was diagnosed and treated accordingly. Next morning, the dog showed neurological symptoms and was diagnosed with tick-borne encephalitis (TBE). Diagnosis was confirmed by a high level of IgG antibodies (922 IU/ml), detected in serum 3 months later. The second dog presented with babesiosis symptoms on the 7th day after return. [i]Babesia[/i] DNA was extracted from blood, amplified and sequenced to answer the question of whether the dogs became infected during the race in Estonia or in Poland. [b]Results and conclusions.[/b] Sequencing of a fragment of[i] Babesia[/i] 18S rDNA revealed that these two isolates were identical to one another and closely related to the [i]B. canis[/i] sequence originally isolated from the dog and [i]Dermacentor reticulatus[/i] ticks in Poland. Thus, this is the first confirmed case of [i]B.canis[/i] and TBEV co-infection and first confirmed case of TBE in a dog in Poland.
