Plain-English summary
A study found that 15 out of 1,427 dogs in Japan tested positive for Anaplasma bovis, a type of bacteria that can infect dogs. This was the first time A. bovis DNA was detected in dogs, and the affected dogs were spread across various regions in Japan. While the exact health effects of this infection on dogs are still unclear, it’s important for pet owners to be aware of potential symptoms and discuss any concerns with their veterinarian. Regular check-ups and preventive care can help keep your dog healthy.

Abstract
The prevalence of Ehrlichia and Anaplasma in 1,427 dogs from 32 Japanese prefectures was evaluated by PCR and DNA nucleotide sequencing. PCR screening demonstrated that 18 dogs (1.3%) were positive for Anaplasmataceae. Sequence analysis revealed that 14 of the amplicons were most closely related to Wolbachia spp., symbionts of Dirofilaria immitis, whereas three were identified as Anaplasma bovis. The remaining amplicon could not be sequenced. Almost the entire sequence of 16S rRNA (1,452 bp) from one of the positive specimens was determined, and subsequent phylogenetic analysis confirmed that the detected sequence was that of A. bovis. This is the first detection of A. bovis DNA fragments in dogs. Species-specific nested PCR showed that 15 (1.1%) of the 1,427 dogs involved in this study were positive for A. bovis. The geographical distribution of these dogs ranged from Aomori Prefecture in northern Japan to Kagoshima Prefecture in the south. The relationship between A. bovis infection and clinical disease is not yet clearly understood.
