Immunotherapy against antibiotic-resistant bacteria: the Russian experience with an antistaphylococcal hyperimmune plasmaand immunoglobulin

The Russian experience with the preparation and clinical application of an antitoxic antistaphylococcal hyperimmune plasma and immunoglobulin is described. The immunotherapies were developed in the late 1960s and put into widespread use in the Soviet Union for the prophylaxis and treatment of sepsis, pneumonia, and other conditions caused by an epidemic of antibiotic-resistant Staphylococcus aureus.     

Production of a hyperimmune antitoxic donor plasma against Pseudomonas aeruginosa

Research work has been carried out with the aim of obtaining hyperimmune antitoxic plasma against Pseudomonas aeruginosa. Hyperimmune plasma active against P. aeruginosa toxin has been obtained from donors immunized with P. aeruginosa toxoid. The preparation is highly specific and active, which is revealed by in vivo and in vitro tests. The clinical study of the preparation indicates its high efficacy in the treatment of diseases caused by different P. aeruginosa serotypes.     

Chemotherapeutic effectiveness of a new derivative of 5-alkyl-3N-furanones in experimental staphylococcal infection

High chemotherapeutic efficacy of the compound 1929, a new derivative of 5-alkyl-3H-furanones was shown in albino mice with experimental staphylococcal infection caused by intraperitoneal administration to the animals. The efficacy was found to be higher than that of furagin used for comparison. The average therapeutic dose (AD50) of the compound for intraperitoneal administration amounted to 40 mg/kg while the average lethal dose (LD50) was 3000 mg/kg.     

Immunosuppression in experimental staphylococcal infection and its effect on antimicrobial resistance

Experiments on CBA and (CBA X C57BL)F1 mice have revealed that a prolonged period of antigen-nonspecific immunosuppression of humoral immunity develops in experimental staphylococcal infection; this period of suppression may be preceded by a short phase of antigen-nonspecific immunostimulation. Immunosuppression is linked with the accumulation of antigen-nonspecific T-suppressors in the spleen, these T-suppressors being capable of the manifestation of their activity both in vitro and in vivo in cases of their transplantation to semi-syngeneic recipients. Immunosuppression does not aggravate the course of staphylococcal infection and is accompanied by an increase in resistance to Pseudomonas aeruginosa superinfection, which is due to the stimulation of inflammatory reaction at the site of the injection of the superinfecting agent.
