Use of quantitative real-time PCR to monitor the response of Chlamydophila felis infection to doxycycline treatment.

ABSTRACT: Fifteen cats infected with Chlamydophila felis were monitored for the presence of C. felis DNA on ocular swabs by using real-time PCR and for clinical signs of disease. The cats were assigned to three groups: oral doxycycline at 10 mg/kg of body weight/day for 7 days (six cats), oral doxycycline at 10 mg/kg/day for 14 days (five cats), and an untreated control group (four cats). The untreated cats remained positive for C. felis throughout the trial; clinical signs were most severe on days 14 to 21 postinfection, and then they declined. Treatment with 7 and 14 days of doxycycline decreased C. felis relative copy numbers and clinical signs rapidly. C. felis became undetectable in some of the cats during or after treatment. However, after the cessation of treatment, a recurrence of high relat
