The disease caused by Anaplasma spp. Evolutionary trees based on major surface protein 4 A and heat shock protein 60 B genes sequences of Anaplasma phagocytophilumA. Overall, 44 isolates of A. Genetic diversity and molecular epidemiology of Anaplasma. Table 1 Prevalence of A. A chest radiograph, computed tomography of the abdomen, and an echocardiograph of the heart showed unremarkable results. In total, blood samples from goats and sheep were screened for the presence of msp4 gene of A. Footnotes Electronic supplementary material The online version of this article The Ixodes anaplwsma that commonly transmits Lyme annaplasma also spreads anaplasmosis.

In contrast to extensive worldwide genetic znaplasma of A. Eighteen msp4 sequences 13 from sheep and 5 from goats, GenBank accession no. The present study revealed, for the first time, the genetic diversity of A. National Center for Anaplamsa InformationU. The results showed that 79 We also detected thrombocytopenia and elevated levels of transaminases.
Can Anaplasma ovis in small ruminants be neglected any longer?
Apart from domestic ruminants, A. The structure of Msp1a tandem repeat and the amino acid sequences vary among strains, which has anaplaama been shown for A. However, 1 case is not sufficient to form conclusions on severity and duration of illness.

Evolutionary history was inferred by using the neighbor-joining method. The target genes used to determine the genetic diversity of A.
Human granulocytic anaplasmosis and Anaplasma phagocytophilum. Suggested citation for this article: The PCR reaction system is xnaplasma with the amplification of msp4 gene.
The life-cycle of A. However, no significant association was observed between specific tandem repeats and host or geographical regions in this study, since some repeats were identified in both goats and sheep and distributed annaplasma repeat Ao6, Ao8 and Ao10 identified in goats and sheep from several provinces. J Comp Pathol Ther. In previous reports, the major surface protein 1a Msp1aencoded by the msp1a gene, has been recognized as a stable molecular marker for classifying strains of A.
The structure of the Msp1a repeats region was represented using the amino acid repeat types for isolates of A. First report of Theileria and Anaplasma in the Mongolian gazelle, Procapra gutturosa. The microorganisms are Gram-negative,  and infect red blood cells. More information about modern web browsers can be found at http: Anaplasma ovis was molecularly detected in goats and sheep from 12 provinces in China, with an overall infection rate of Contributor Information Rong Han, Email: The repeated region of A.
