Identification and phylogenetic analysis of novel Piroplasmida detected in the two-toed sloth (Choloepus didactylus).
This study investigated the pathological and parasitological causes of death in two two-toed sloths (Choloepus didactylus) housed at a zoo in Hokkaido, Japan. Genomic DNA was extracted from the clotted blood of these animals and subsequently examined by nested PCR assays targeting the 18S rRNA and β-tubulin genes. The nucleotide sequences of these genes were determined and a phylogenetic analysis of the 18S rRNA gene was performed. One sample was detected positive in nested PCR. Sequencing analysis revealed that the detected parasite was closely related to the order Piroplasmida and was subsequently designated as Piroplasmida sp. Choloepus didactylus-1 (Piroplasmida sp. CD-1).
期刊介绍:
JVMS is a peer-reviewed journal and publishes a variety of papers on veterinary science from basic research to applied science and clinical research. JVMS is published monthly and consists of twelve issues per year. Papers are from the areas of anatomy, physiology, pharmacology, toxicology, pathology, immunology, microbiology, virology, parasitology, internal medicine, surgery, clinical pathology, theriogenology, avian disease, public health, ethology, and laboratory animal science. Although JVMS has played a role in publishing the scientific achievements of Japanese researchers and clinicians for many years, it now also accepts papers submitted from all over the world.
