RESUMO

The purpose of this report was to study the role of T lymphocytes following injection of Porphyromonas gingivalis in a mouse abscess model. Three invasive P. gingivalis isolates (ATCC 53977, W83, and AJW4) were injected into athymic BALB/c mice and their heterozygous (nu/+) littermates. The athymic BALB/c (nu/nu) mice were able to localize the invasive P. gingivalis isolates at the injection site. By comparison, the heterozygous BALB/c (nu/+) littermates developed hemorrhagic secondary lesions within 24 h after subcutaneous injection of the same invasive P. gingivalis isolates. These results suggest that naive T lymphocytes may contribute to the pathology associated with P. gingivalis infection.
