Aileen Marty of the AFIP was able to demonstrate the bacteria in human tissues using standard stains, and later proved that the organisms were indeed Ehrlichia using immunoperoxidase stains.

Rickettsia felis Flea-borne spotted fever. Clinical improvement is seen in the first hours unless co-infections not susceptible to doxycycline are present such as protozoal vector-borne agents, or if other complications develop such as severe bleeding.

In Europe, two tick species are mainly involved: Ann N Y Acad Sci This strain, despite its tropism for platelets, is closely related to others identified in ruminants Zobba et al.


Rickettsial pathogens are transmitted to humans by competent vectors. Am J Trop Med Hyg ; However, a recent study demonstrated that some genus-specific PCRs also detect Pseudomonas sequences and may lead to false positive results that may only be recognized after sequencing analysis Hofmann-Lehmann et al.

The latter two infections are not well studied. Cell tropism and molecular epidemiology of Anaplasma platys -like strains in cats.

The natural disease has been confirmed by molecular testing only in a few cases and mainly manifests as non-specific signs such as fever, anorexia and lethargy, but more rarely hyperesthesia, joint pain, pale mucous membranes, lymph node and spleen enlargement, and haemorrhagic diathesis petechiae, vitreous haemorrhage have also been reported Lappin and Breitschwerdt, Infectious diseases of the dog ehrlichoisis cat.

Regular application of ectoparasiticides to pets reduces the risk of exposure of humans to vectors of rickettsial agents. Animals generally respond well to treatment but may remain persistently infected.

Little information is available on the pathogenesis of these agents in cats. Blood PCR analysis is a sensitive and specific method for confirming diagnosis at the onset of acute clinical signs when antibody testing is usually still negative Foley et al. Clinical signs are usually reported soon after tick infestation. Reprinted with permission from Adaszek et al.

Similar rates were found in healthy cats as compared to those showing clinical signs. Expert Review of Anti-infective Therapy. They are mostly non-specific and consist of fever, anorexia, lethargy and dehydration. Retrieved from fhrlichiosis https: In fact, a transient lymphopenia was the only abnormality 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.
