The first molecular detection of Anaplasma capra in domestic ruminants in the Central Part of Turkiye, with genetic diversity and genotyping of Anaplasma capra

Abstract

Tick-borne diseases have been an increasing threat to human and animal health all over the world. Anaplasmosis, is one of the emerging-tick borne diseases, has zoonotic potential. A new novel species, which was detected in China in 2010-2012 and provisionally named Anaplasma capra in 2015, causes zoonotic infections and infects many different animal species. In this study, we investigated that presence of A. capra in domestic ruminants from Turkiye. A total of 468 blood samples (cattle, sheep, and goat) were examined by the gltA gene-specific nested polymerase chain reaction, revealing the presence of A. capra in six samples (1.28%) one of them from cattle (0.41%) the others five from sheep (3.22%). According to DNA sequences results of the gltA gene, A. capra isolates identified in the present study were shown high nucleotide similarity with A. capra isolates detected from different hosts. However, the nucleotide differences were detected in the same nucleotide positions between A. capra isolates. For this reason, we thought that at least two different A. capra genotypes could be circulating in the world. As a result, it is seen that A. capra, which was determined to be a new species with zoonotic potential, was revealed in European and Asian countries and in different hosts. In order to raise awareness about human anaplasmosis infections, it is important to reveal the prevalence of the species in the world. The emergence of A. capra in Turkiye reveals the need for a re-evaluation of the human and animal health risk analysis in terms of anaplasmosis.
