intra-abdominal inflammation, or the presence of foreign bodies is well documented in the literature [9–11]. In all six investigated samples, numerous concomitant bacteria were isolated together with A. funkei, which is congruent with the previous reports on Actinomyces species being frequently found in polymicrobial infections [9,12]. On the other hand, occurrence in mixed cultures could mean that this species is frequently overlooked in the routine evaluation of microbiological cultures. Identification of this species using conventional biochemical tests can be misleading and false because A. funkei is not deposited in the Api CoryneTM database. Ng et al. [13] have reported that MALDI-TOF mass spectrometry is a promising tool for identification of different aero-tolerant Actinomyces spp. including A. funkei, but improvement of the database may increase the confidence of species identification.
