The Bi-Digital O-Ring Test has been very useful in the identification of bacterial and viral infections, as well as other etiological agents, in difficult clinical cases. Case report of a patient with multiple hepatic abscesses (pylephlebitis induced hepatic abscess is the most difficult abscess to treat), in which the etiological agent was suggested through Bi-Digital O-Ring Test with excellent clinical evolution after modification of previously ineffective multi anti-microbial treatment is presented. 45 years old, female with a history of pain at right hypochondria for 15 days, with jaundice, oscillating fever and shivering. Computerized tomography showed liver with multiples nodules in the parenchyma with additional appendicitis. An appendectomy was performed with drainage of intra abdominal abscesses. Treatment with metronidazol, ceftazidim and amicacine was performed with no improvement while the general condition of the patient was deteriorating progressively in the following 3 weeks. Bi-Digital O-Ring Test was then performed to determine the etiological agent and the drug compatibility test among effective antimicrobial agents. Based on the Bi-Digital O-Ring Test, the main etiological agent was found to be Enterobacter aerogenes. Amongst the three antibiotics that were being used, only metronidazol was effective and the other 2 was cancelled its effect. Based on Bi-Digital O-Ring Test findings two new antibiotics (cefadroxil and imipenen), were added to metronidazol and additional cilantro tablets by Hayashibara, Japan was given, and Selective Drug Uptake Enhancement Method performed, with excellent clinical, laboratory testing and tomography improvement within 10 days. Bi-Digital O-Ring Test suggested the etiological agent, and effective and mutually compatible antibiotics for treating the abscesses which resulted in a good clinical evolution, characterized by relief of fever and reduction of the hepatic abscesses in a short period and followed complete disappearance of hepatic abscess.
