[Efficacy of probiotic bactisporin in therapy of intrahospital urinary infection].

We studied efficacy of bactisporin (probiotic based on aerobic spore-forming culture Bacillus subtilis, strain 3H) in combined treatment of intrahospital urinary infection (IUI) in 36 patients with infravesical obstruction. These patients developed postoperative complications due to IUI caused by antibiotic-resistant hospital flora. The control group consisted of 35 patients matched by age and disease given conventional postoperative etiotropic therapy. Bacterial translocation enables bactisporin to enter blood through gastric mucosa. Blood flow delivered the drug to the inflammation focus. Bactisporin can also directly affect IUI pathogen if bacterial suspension is introduced into the cavity. Bacteriological efficacy of the etiotropic scheme including bactisporin against Proteus spp., Ps aeruginosa, Enterobacter spp., Klebsiella spp. made up 72.7-92%. Bactisporin shortened the time of clinical normalization as well as normalization of absolute count of T- and B-lymphocytes, phagocyting leukocytes and immunoglobulin G. Thus, probiotic bactisporin is effective against antibiotic-resistant agents of IUI. It also stimulates immunity promoting clinicoimmunological remission.
