Severe Monomicrobial Abdominal Actinomycosis When Intravenous Penicillin G Has Not Resolved Infection

This protocol applies when a patient with severe monomicrobial abdominal actinomycosis — life-threatening organ involvement or multiple organ involvement, with no penicillin allergy — has completed an initial course of intravenous penicillin G without achieving resolution of infection.

Clinical Scenario

The patient has monomicrobial actinomycosis classified as severe: the infection involves an organ causing life-threatening disease, or it involves multiple organs. There is no penicillin allergy. This degree of organ involvement distinguishes severe disease from mild monomicrobial actinomycosis.

Prior Treatment Non-Response

An initial course of intravenous penicillin G was the first-line approach for this severe presentation. The goal — resolution of actinomycosis infection, expected within 6 to 12 months — was not reached. Non-achievement of that resolution endpoint is the clinical trigger that escalates management to this protocol.

Next-Step Approach (Partial)

When intravenous penicillin G does not resolve severe abdominal actinomycosis, the management pathway includes a surgical component — specifically debridement and resection of affected tissue. The complete structured protocol details the full management pathway beyond this partial overview.
