For the foot-pad test, heat-killed cells of F. necrophorum were found to be better than viable bacteria as eliciting antigens. Since F. necrophorum is found in a wide clinical spectrum from asymptomatic carriage via chronic throat symptoms to acute and sometimes severe infections, a positive throat culture or molecular test for F. necrophorum is a true challenge for the clinician. F. necrophorum has not featured prominently; thus, in one study of tonsils excised from children aged 4 to 15 years, F. necrophorum was detected in only 2 of 25 samples . Equally, it has been very difficult to establish with certainty whether anaerobes have a causative role; these organisms might simply reflect an environment created by tonsillar scarring that was more favorable for anaerobes. The described FISH assay offers the perspective for the direct species identification of F. necrophorum and F. nucleatum in positive blood cultures within a few hours and at the same day of positivity, and directly in clinical specimen such as polymicrobial abscesses, but it surely needs to be further evaluated. There is a rapid test for strep; but there is not a routine, commercially available rapid test for F. necrophorum.

pathogenesis of F. necrophorum infection. Despite these excellent clinicopathological descriptions, there was considerable confusion about the causative organ-ism, partly related to duplication of names for F. necrophorum but also due to misattribution of a causal role to organisms such as streptococci (3, 180, 250), probably because of inade- F. necrophorum may be very virulent in certain types of infections. In postanginal sepsis (Lemierre's syndrome) the infection begins with a membranous infection, such as tonsillitis, and proceeds to septicemia with metastatic infection that can include lung abscess, empyema, liver abscess, ostemyeletis, and purulent arthritis. F. necrophorum produces hemagglutinin which causes platelet aggregation that can lead to diffuse intravascular coagulation and thrombocytopenia. Diagnosis.

necrophorum is difficult to culture because it is an anaerobic bacterium requiring special methods to grow it in a lab.
