[Sensitivity and resistance of aerobic bacteria isolated from patients with periodontitis towards antibiotics and bacteriophages (comparative analysis)].

In order to examine sensitivity and resistance of isolated aerobic bacteria from periodontitis materials towards antibiotics and bacteriophages, there has been studied exudations taken from 737 patients' periodontic pockets or the tissue taken from curettage. According to the rate of identified microorganisms, they have been arranged as follows: S. epidermidis 39,34+/-1,56%; S. pyogenes 18,84+/-1,25%; M. catarrhalis 17,09+/-1,2%; S. aureus 10,71+/-0,99%; E.coli-5,66+/-0,74%; Diphtheroids in 1,13+/-0,33%; S. Mucilaginosus 1,02+/-0,32%, proteus vulgaris - 0,72+/-0,27%; H. parainfluenzae - 0,72+/-0,27%; S. intermedium 0,61+/-0,24%; P. aeruginosa - 0,61+/-0,24%; H. influenzae - 0,51+/-0,22%, S. saprophiticus - 0,51+/-0,22%; S. viridans - 0,51+/-0,22%; S. pneumoniae - 0,41+/-0,2%; K. pneumoniae - 0,41+/-0,22%; S. haemoliticus - 0,41+/-0,2%; B. adolescentics - 0,3+/-0,17%; L. acidophilus -0,3+/-0,17%; S. salivarius-0,1+/-0,1%. It has been stated that percentage of polyresistant strains is growing. While having aerobic infections of periodontitis, kefzol, cephazolin, cephamezin, zinaceph, klaphoran, cephdazidim (cephalosporins I, II, II generation); tetracycline, doxycycline, (tetracyclines); 5-noks, cyprophloxacyne (chinolons I, II generation); ryphamphcyne (rymphamicynes); but standby medicines may be also considered: penicillin G, procaine penicillin (penicillines); streptomycin, kanamicin, gentamicin (aminoglycosides); lincomycin, clindamycin, (lincosamides); eritromycin, macropen (macrolides); chloramphenicol. Since the resistance of microbial strains was not developed towards bacteriophages during the treatment it is considerable to apply simultaneously the bacteriophages and standby antibiotics.
