Canine anaplasmosis is regarded as an infection by Anaplasma platys rather than zoonotic Anaplasma phagocytophilum in subtropical areas based on the assumption that the common dog tick species is Rhipicephalus sanguineus, which transmits E. canis and presumably A. platys. We investigated asymptomatic dogs and dog ticks from 16 communities in Nantou County, Taiwan to identify common dog tick spe...

The aims of this study were to determine the occurrence of Anaplasma platys and Ehrlichia canis infection in dogs in Porto Alegre, Southern Brazil; and to investigate their association with hematological abnormalities. Serum samples from 196 dogs were first tested using dot-ELISA for antibodies against Anaplasma spp. and Ehrlichia canis. Peripheral blood samples from 199 dogs were subjected to ...

A total of 27 ticks, comprising Rhipicephalus sanguineus (Latreille) (n = 21), Haemaphysalis leachi (Andouin) (n = 4) and Haemaphysalis paraleachi (Camicas, Hoogstraal & El Kammah) (n = 2) were recovered from two clinically healthy female dogs in the Democratic Republic of the Congo. DNA of Anaplasma platys was detected in a female R. sanguineus, using primers derived from the 16S rRNA gene, wh...

Anaplasma platys infects peripheral blood platelets and causes infectious cyclic thrombocytopenia in canines. The genes, proteins, and antigens of A. platys are largely unknown, and an antigen for serodiagnosis of A. platys has not yet been identified. In this study, we cloned the A. platys major outer membrane protein cluster, including the P44/Msp2 expression locus (p44ES/msp2ES) and outer me...

Following the accidental finding of inclusion bodies similar to Anaplasma platys in a stained blood smear from a cat, DNA analysis of the 16S rRNA gene was performed and 100% identity was found with different strains of A. platys. These data confirm that cats are susceptible to parasitism by A. platys.

INTRODUCTION Little information is currently available regarding the presence of Anaplasma species in North African dromedaries. To fill this gap in knowledge, the prevalence, risk factors, and genetic diversity of Anaplasma species were investigated in Tunisian dromedary camels. METHODOLOGY A total of 226 camels from three different bioclimatic areas were sampled and tested for the presence ...

anaplasma platys, previously known as ehrlichia platys,which causes infectious canine cyclic thrombocytopenia, has notbeen extensively studied in southeast asia. recent reports in theregion have been limited to ticks and dogs in thailand, and toticks in the philippines. in this report, dnafragments of a. platyswere molecularly detected in a dog in the philippines. apitbullpuppy exhibited pancyt...

This study reports for the first time molecular detection of Anaplasma platys infection in 4 (13.3%) of 30 Malaysian dogs investigated. A low occurrence (3.3%) of Babesia gibsoni was also noted, being detected in one of the 30 dogs. Rickettsia, Bartonella, Orientia tsutsugamushi, and Ehrlichia DNA were not detected in the dog blood samples. The role of A. platys as an agent of canine anaplasmos...

This study investigated the frequency of infection by Anaplasma platys and Ehrlichia canis in dogs submitted to animal health centers in Campo Grande, state of Mato Grosso do Sul, Brazil. E. canis and A. platys showed infection frequencies of 55.75% and 16.96%, respectively. The identity of the two species was confirmed by DNA sequencing.
