Extracellular Bartonella henselae and artifactual intraerythrocytic pseudoinclusions in experimentally infected cats

Vet Microbiol. 2000 Oct 1;76(3):283-90. doi: 10.1016/s0378-1135(00)00240-6.


Blood, spleen and liver of specific pathogen-free (SPF) cats and SPF cats experimentally infected with Bartonella henselae were examined. Using immunohistochemical labeling, no intracellular B. henselae were observed in tissues of any cats, but extracellular B. henselae were detected in tissues of infected cats. Pseudoinclusions were detected in erythrocytes of all cats using electron microscopy.
