  • Otorhinolaryngeal and respiratory bacterial infections including: rhinitis, otitis, paranasal sinusitis, pyogenic tonsillitis, pharyngitis, laryngitis, tracheitis, bronchitis, pneumonia, pleuritic;
  • Dermatological bacterial infections including: pyoderma, abscesses, furunculi and carbuncles, hydradentitis;
  • Surgical site bacterial infections including: infectious wounds, mastitis, flegms;
  • Oral bacterial infections including: stomatitis, gingivitis, periodontitis and other;
  • Ocular bacterial infections including: conjunctivitis, blepharitis;
  • Burn wounds with secondary bacterial infections
  • Urogenital and gynecological infections: Urethritis, cystitis, pyelonephritis, colpitis, endometritis;
  • Gastrointestinal bacterial infections including: gastroenterocolitis, dysbacteriosis (bacterial overgrowth syndrome), paraproctitis;
  • Omphalitis of newborn, purulent septic infections in children (including newborn);
  • Infectious diseases lead by Staphylococcus (S. aureus), Streptococcus (S.pyogenes, S. sanguis, S.salivarius, S. agalactiae), E.coli (Different types), Pseudomonas Aeruginosa, Proteus (Mirabilis and Vulgaris) bacteria;
  • Prophylactic purposes against post-operational complications and hospital infections;

Usage and dosage:

Optimal results are achieved when Pyo bacteriophage is used at the onset of infection and when introduced directly to the infection site. Pyo bacteriophage is used as a disinfecting agent by phage soaked bandages applied directly into a cavity (wound, including abscess, abdominal, pleural, nasal, urinary bladder, uterine, vaginal) The preparation may be used orally per os, and/or by urinary catheter or rectally per rectum via enema.

– Local application of Pyo bacteriophage is performed daily during 3-5 day period, three times a day. Amount of the preparation is determined by the size of the affected area. If various chemical antiseptics were used to treat the wound before phage application, it should be cleaned by sterile saline solution and 2-3% soda solution should be applied.

– For treatment of abscesses, pleuritis, arthritis, and peritonitis, 50-200ml of Pyo bacteriophage may be instilled directly into the cavity, every other day. (Exact amount of applied phage is determined based on the size of cavity) Before instillation of bacteriophages, pus from cavities should be extracted.

– For cystitis and pyelonephritis Pyo bacteriophage may be administered via urinary catheter or per os;

– During cholecystitis, Pyobacteriophage can be applied through intubation with amount of 30 ml every other day.

– In case of stomach surgery or peritonitis, 100ml phage is applied in cavity, daily during 3-4 days. In case of application through catheter 30ml phage is applied daily during 3-4 days.

– For treatment of deep forms of pyoderma. Intradermal injection may be used (0.1-0.5 ml per injection) up to maximum of 10 injections during 24 hours.

– For conjunctivitis, Pyo bacteriophage is instilled via pipette, 2 drops in each eye, 4-6 times daily during 3-5 days.

– In cases of neonatal omphalitis and pyoderma, application is by Phage soaked bandage twice daily for 5-7 days.

During Per os application of Pyobacteriophage in adults and children from age of 3, drinking of 2-3% baking soda solution (one glass, 150-250 ml) is recommended.
