The official, Dr. Kimberly Lindsey, is a deputy director with the CDC's Laboratory Science, Policy and Practice Program Office.
Lindsey, 44, was arrested Sunday along with her boyfriend, Thomas Westerman, MyFoxAtlanta.com reports. Lindsey is being held in the DeKalb County Jail on a $25,000 bond, while Westerman was release on a $16,000 bond.
The arrest warrant said Lindsey and Westerman, also a CDC employee, are accused of making the child participate in sexual play, MyFoxAtlanta.com reported.
Police were tipped by a medical professional in August to the alleged molestation, and the arrest warrant cited incidents in August and in January 2010, the Atlanta Journal-Constitution reported.
"During the investigation, evidence was recovered that led to the bestiality charge," DeKalb police spokeswoman Pamela Kunz told the newspaper.
Lindsey's work with the CDC involves oversight of the agency's $1.5 billion fiscal allocation process for terrorism preparedness and emergency response, according to the CDC's website.
