ABSTRACT
Uveitis associated with Ehrlichia canis or Anaplasma platys infections were reported in dogs. However, only two E. canis-infected dogs with hypergammaglobulinemia showed acute blindness were reported. There were limited data of the species of Ehrlichia or Anaplasma and the alteration of serum protein fractions in infected dogs. Thus, the species of causative pathogen were investigated and compared the serum protein fractions between infected dogs associated with anterior uveitis and panuveitis in clinical situations. All 103 studied dogs were brought into the ophthalmology clinic which each dog showed signs of unilateral or bilateral uveitis related to ehrlichial infection. Dogs were divided into anterior uveitis and panuveitis groups. The species of Ehrlichia or Anaplasma were identified using nested-PCR based on the 16S rRNA gene and DNA sequencing from blood samples. The serum protein fractions were analyzed using electrophoresis. Fifty-eight dogs (56.31%) were positive of which E. canis and A. platys were detected in 51 and 7 dogs, respectively. The total serum protein and globulin levels were higher in the infected dogs associated with panuveitis than anterior uveitis while the albumin levels were significantly lower in the panuveitis group. The A/G ratios significantly decreased in both groups. Gamma globulin was detected at high levels in both groups while beta globulin significantly increased in the panuveitis group. Hypergammaglobulinemia was detected in 76.92 and 90.90% of infected dogs associated with anterior uveitis and panuveitis, respectively. Most of the infected dogs associated with panuveitis showed significantly levels of hyperproteinemia, hyperbetaglobulinemia and hypergammaglobulinemia compared with anterior uveitis group. E. canis was found as the major pathogen in infected dogs associated with uveitis in this study.
