Ehrlichiosis – Wikipedia

Ehrlichia are transported between cells through the host cell filopodia during initial stages of infection, whereas, in the final stages of infection the pathogen ruptures the host cell membrane. Anti-nuclear antibodies were found in some cats and neutrophilic polyarthritis was diagnosed in a cat with joint signs Breitschwerdt et al.

These obligate intracellular bacteria infect and kill white blood cells. Both species are found also on cats Jameson and Medlock, ; Claerebout et al. They are mostly non-specific and consist of fever, anorexia, lethargy. For people allergic to antibiotics of the tetracycline class, rifampin is an alternative. Rickettsia typhi Murine typhus Rickettsia prowazekii Epidemic typhusBrill—Zinsser diseaseFlying squirrel typhus. Regular application of ectoparasiticides to pets reduces the risk of exposure of humans to vectors of rickettsial agents.

No human vaccine is available for ehrlichiosis. Just as in humans and dogs, co-infections with multiple vector-borne pathogens occur in cats; the consequences of such mixed infections are unknown Maia et al.

However, mild reduction in total leukocyte, neutrophil and lymphocyte counts, remarkable reduction in PCV values, and transient increase of ALT and AST values were detected Foley et al. In fact, a transient lymphopenia was the only cais detected during 13 weeks of observation after tick infestation, concerning general appearance, appetite, body temperature and cell blood count of the experimental cats Lappin et al.

This is more than twice the estimated incidence for the years Bacterium-related cutaneous conditions Tick-borne diseases. Clinical improvement is seen in the first hours unless co-infections not susceptible to doxycycline are present such as protozoal vector-borne fels, or if other complications develop such as severe bleeding.

This disease was described in tropical and temperate areas worldwide, with the exception of Australia.
