Impacts of Antiretroviral Therapy on the Oral Microbiome and Periodontal Health of Feline Immunodeficiency Virus Positive Cats.

Feline Immunodeficiency Virus (FIV) is the viral analogue to HIV in humans, and both infections are associated with oral disease. Our study explored how antiretroviral treatment affects the oral health and microbiome of domestic cats infected with FIV. Cats treated with antiretroviral therapy had less gum inflammation and a different community of oral bacteria compared to untreated FIV-positive cats. This suggests that antiretroviral therapy not only helps in controlling FIV infection but also benefits feline oral health. These findings advance our understanding of antiretroviral treatment for lentiviral-associated oral disease and highlight FIV as a valuable experimental model for the similar condition in humans.
