Culture on 5% sheep blood agar media by Fortner's method was examined daily without disturbing the partial anaerobic condition which after 10 days yielded growth of Actinomyces israelii. Fungal culture was negative.
Actinomyces israelii was identified from findings of Gram-positive extremely fine filamentous forms (see Fig.3), non-pigmented and non-hemolytic irregular rough colony morphology (see Fig.2), Catalase negativity, positive nitrate reduction test, negative urea hydrolysis test, negative Voges-Proskauer reaction and by extended biochemical tests to determine different sugar fermentation (see Table).
At 3 months post-therapy, significantly higher levels of Actinomyces israelii, Campylobacter rectus, Fusobacterium periodonticum, Parvimonas micra, Prevotella nigrescens, Tannerella forsythia, Neisseria mucosa, and Streptococcus anginosus were found in the CKD group compared with the C group (p < 0.05, Mann-Whitney test).
