Method of preventing or treating a Pseudomonas aeruginosa infection. Method comprises topical application of antibodies to P. aeruginos under conditions and in an amount sufficient to prevent or treat the infection in a mammal. In one embodiment, the antibodies are administrered in form of an aerosol. A preferred dosage for polyclonal antibody preparations (i.e. ISG or high titer P. aeruginosa ISG) ranges from 2 mg/kg to 100 mg/kg body weight of the mammal. A preferred monoclonal antibody dosage ranges from 0.02 to 1.0 mg/kg of body weight.

Topical use of antibodies for prevention or treatment of pseudomonas

A method and system is disclosed for introducing anti-bacterial agents, for example, quinolone carboxylic acid derivatives into blood bag systems for preventing massive bacteria growth in stored blood and blood components. The quinolone carboxylic acid derivative can be added to a collection container before, during or after the collection of blood and blood components. The addition of a quinolone carboxylic acid derivative to blood bag systems allows for increase in storage time for blood and blood components without the threat of massive bacterial contamination.

Normal plasma from donors who have not been vaccinated with a P seudomonas vaccine or had a Pseudomonas infection can be screened for higher than normal titers of naturally occurring antibody to four or, preferably, two of seven Fisher Immunotypes of Pseudomonas. Those plasmas with higher titers of such antibody can be pooled and fractionated to give hyperimmune serum globulin having high titers of antibody against all seven Fisher Immunotypes. The product may be treated to render it intravenously injectable and the so-prepared material is effective in treating patients with Pseudomonas infection. Also disclosed is a novel antibody preparation including minimum titers of the seven Fisher Immunotypes.

High titer pseudomonas immune serum globulin

A method for increasing the survival rate in hypercatabolic mammals following the onset of burn wound sepsis. The method comprises orally administering to the mammal, sufficient doses of ciprofloxacin to attain high concentrations in extra vascular fluid, and parenterally administering to the mammal, Pseudomonas immune globulin. The combination therapy of treating Pseudomonas burn wound sepsis with ciprofloxacin and Pseudomonas immune globulin results in a higher rate of survival than the treatment utilizing a single agent. This suggests a synergistic interaction between the two agents in the therapy of polymicrobial burn wound sepsis.

Method of treating polymicrobial burn wound sepsis with a combination

Monoclonal antibodies specific to serotypic determinants on the flagella of a microorganism and found to be useful in inhibiting motility.

Protective antibodies to serotypic determinants of flagellar antigens

There is disclosed an immunizing composition comprising a non-toxic polysaccharide isolated from gram-negative bacteria, especially from Pseudomonas aeruginosa, covalently coupled to a non-toxic protein from the gram-positive bacterium Micrococcus luteus by means of a 4-12 carbon moiety. To prepare the above immunizing agent, the lipid A portion of lipopolysaccharide from a gram-negative bacterium is separated to give a non-toxic polysaccharide. Reactive aldehyde groups are generated on the non-toxic polysaccharide by selective oxidation. The non-toxic polysaccharide is then covalently coupled to a non-toxic protein isolated from said gram-positive bacterium, Micrococcus luteus, by means of a polyfunctional compound having 4-12 carbon atoms and having at least two functional groups which are reactive to the aldehyde groups on the non-toxic polysaccharide and to the carboxylic groups on the non-toxic protein.

Vaccine for Pseudomonas aeruginosa

An immunizing composition is disclosed and comprises a detoxified polysaccharide from a gram-negative bacterium covalently coupled to a detoxified protein from said gram-negative bacterium by means of a 4-12 carbon moiety. To prepare the above immunizing agent, the lipid A portion of lipopolysaccharide from a gram-negative bacterium is separated to give a detoxified polysaccharide. Reactive aldehyde groups are generated on the detoxified polysaccharide by selective oxidation. The detoxified polysaccharide is then covalently coupled to a detoxified protein from said gram-negative bacterium by means of a 4-12 carbon moiety having functionalities reactive to the aldehyde groups on the detoxified polysaccharide and to the carboxylic groups on the detoxified protein.

Vaccines for gram-negative bacteria

Normal plasma from donors who have not been vaccinated with a Pseudomonas vaccine or had a Pseudomonas infection can be screened for higher than normal titers of naturally occurring antibody to four of seven Fisher Immunotypes for Pseudomonas. Those plasmas with higher titers of such antibody can be pooled and fractionated to give hyperimmune serum globulin having high titers of antibody against all seven Fisher Immunotypes. The product may be treated to render it intravenously injectable and the so-prepared material is effective in treating patients with Pseudomonas infection.
