Early diagnosis of canine ehrlichiosis favors prompt institution of treatment and improves the prognosis for the animal, since this disease causes mortality among dogs. Studies have shown that determining the concentration of acute-phase proteins (APPs) may contribute towards early detection of disease and aid in predicting the prognosis. This study aimed to evaluate the APP profile in dogs exp...

A total of 374 dogs, 252 from five military kennels and 122 privately owned, were tested for Ehrlichia canis antibody. Sera were tested at a 1:20 dilution by indirect fluorescent antibody with the use of E. canis cell-culture antigen slides. The overall prevalence of E. canis antibody was 33%. Antibody prevalence among military dogs (29%) was significantly lower than among privately owned dogs ...

Ehrlichiosis is the multiorgan infectious disease caused by small, intracellular rickettsias from the genus Ehrlichia. These microorganisms are known as an etiologic factor of infections world wide in humans and in different species of animals. Dog ehrlichiosis can be caused by several species of Ehrlichia attacking different groups of blood cells, but most often an infection by Ehrlichia canis...

Although tick-borne pathogens are of tremendous historical importance to both veterinary and human medicine, recent events emphasize an expanding role for newly discovered, as well as previously recognized tick-transmitted organisms, as a cause of animal and human suffering. One of the most important new developments related to anaplasmosis and ehrlichiosis is the realization that a given mamma...

To elucidate whether acute-phase protein responses occur in dogs infected with Ehrlichia canis, C-reactive protein (CRP) and alpha 1-acid glycoprotein (AAG) levels were serially measured in the plasma of five dogs experimentally inoculated with E. canis and 10 sham-inoculated or noninoculated control dogs. The CRP concentration was measured by a canine-specific capture enzyme-linked immunosorbe...

Rhipicephalus sanguineus ticks transmit Ehrlichia canis, the etiologic agent of canine ehrlichiosis. In experimentally infected ticks, only p30-10 transcript was detected among 22 p30 paralogs encoding immunodominant major outer membrane P30 proteins of E. canis. The present study revealed transcription of p30-10 by E. canis in naturally infected ticks and sequence conservation of p30-10 genes ...
