Prolonged Bartonella henselae Bacteremia Caused by Reinfection in Cats
نویسندگان
چکیده
We analyzed the genetic relatedness of blood culture isolates of Bartonella henselae from 2 cats of patients with cat-scratch disease at admission and after 12 months. Isolates from each cat at different times were clonally unrelated, which suggested reinfection by a second strain.

Bartonella henselae infection in cats: evaluation during primary infection, treatment, and rechallenge infection.
Bartonella henselae infection was established in eight cats of various ages by experimental inoculation. All cats remained persistently bacteremic until they were treated 4 to 7 weeks after primary inoculation. Antibody titers increased and peaked between 4 and 12 weeks for all cats. Treatment with doxycycline for 1 week was effective in suppressing bacteremia in all cats but was effective in c...
متن کاملInfection and re-infection of domestic cats with various Bartonella species or types: B. henselae type I is protective against heterologous challenge with B. henselae type II.
Four Bartonella species have been isolated from domestic cats, of which two serotypes/genotypes of Bartonella henselae and possibly B. clarridgeiae are human pathogens, causing cat scratch disease (CSD).Our objectives were to evaluate infection and potential cross-protection during re-infection in domestic cats with various Bartonella species or types.Thirty-six cats were primarily inoculated w...
متن کاملPassive antibody to Bartonella henselae protects against clinical disease following homologous challenge but does not prevent bacteremia in cats.
We challenged cats transfused with anti-Bartonella serum and kittens born to antibody-positive queens with Bartonella henselae to determine the contribution of antibodies to the control of B. henselae in cats. In both experiments, antibody-positive cats were protected from clinical disease but passive antibody to the homologous strain of B. henselae did not prevent bacteremia.
متن کاملPrevalence of Bartonella infection in domestic cats in Denmark.
Whole blood and serum from 93 cats (44 pets and 49 shelter/stray cats) from Denmark were tested for the presence of feline Bartonella species by culture and for the presence of Bartonella antibodies by serology. Bartonella henselae was isolated from 21 (22.6%) cats. Bacteremia prevalence was not statistically different between shelter/stray cats (13/49, 26.5%) and pet cats (8/44, 18.2%), but va...
متن کاملIntraerythrocytic presence of Bartonella henselae.
Recent reports in the medical literature emphasize the risk of zoonotic disease and the high degree of prevalence of asymptomatic feline infection with Bartonella (Rochalimaea) henselae. While investigating Bartonella bacteremia in cats, we used transmission electron microscopy to demonstrate B. henselae in the erythrocytes of persistently bacteremic cats.
