Benefits of technology

[0020]The object of the present invention is to reduce or eliminate the problems disclosed above in connection with Staphylococcus induced infections and conditions.

Problems solved by technology

Staphylococcal enterotoxins produced when these strains are allowed to grow in improperly stored food are a common cause of food poisoning leading to vomiting and diarrhoea.
Deeply situated S. aureus infections can be very severe.
It often causes complications.
Large pimples in those areas will, when popped, cause the worst of the infection.
There are a number of problems with these antibiotics, mainly centred around the need for intravenous administration (there is no oral preparation available), toxicity, and the need to regularly monitor drug levels by means of blood tests.
There are also concerns that glycopeptide antibiotics do not penetrate very well into infected tissues.
Glycopeptides must not be used to treat methicillin-sensitive S. aureus as outcomes are inferior.
Long-term carriers have a higher risk of infection and may also spread the MRSA to other people.
Prophylaxis against Staphylococcus infections is difficult, and vaccination is not a very effective way.
Thus, in particular MRSA has become a major problem in hospitals in many countries and the spread of MRSA has to be prevented.

In Vitro Test

Production of a Lactobacillus PBS Filtrate:

[0061]Lactobacillus LB21 was cultured in 5 ml MRS broth (37° C., 5% CO2, 8 h). 1% (450 μl) LB21 culture was reinoculated in 6 tubes containing 45 ml fresh pre-heated MRS broth and was incubated at 37° C. and 5% CO2 for 16 h. Thereafter the tubes were centrifuged at 3800 rpm at 20° C. for 20 min. The supernatants were discarded and the pellets were resuspended in 5 ml pre-heated PBS and incubated at 37° C. and 5% CO2 for 5 h. Once an hour the tubes were gently mixed. After the incubation, the tubes were centrifuged at 3800 rpm at 8° C. for 20 min. All the supernatants were collected in a new tube, and the pH was measured (4.0-4.3) The supernatants were then sterile filtered through a 0.22 μm filter. The filtrates were stored in −20° C. in aliquots of 1 ml in 10 ml tubes until use.

In Vitro Test

[0066]A combination of different Lactobacillus strains and an α-Streptococci mix of α89a, α502, α505, α4, and α6 was further tested in view of the capacity to inhibit and kill MRSA strains using the PBS supernatant method. At start the cfu was 2×105 / ml of MRSA in the tubes. After 4, 6, 8, 10, 16 and 24 hours samples were taken. The results expressed in cfu / ml can be seen in the table below. The surprisingly better effect by the combination of Lactobacillus and α-Streptococci is due to a synergistic effect of the substances, e.g. specific acids and bakterocins, that are produced by the different strains. sup=supernatant

In Vitro Test of Other Combinations

[0067]A further test was done according to Example 2a) but with new combinations of bacteria. Here LB931 and LB Ess-1 were tested in a combination with α89a and Streptococcus lactis L1A, and the concentration of remaining MRSA were measured after different time periods. The test strain was MRSA 22.

Abstract

A pharmaceutical preparation for prophylaxis against and treatment of Staphylococcus induced infections or conditions in humans and animals, is disclosed, wherein it comprises a combination of a) one or more viable α-Streptococcus strains chosen from the group consisting of the Streptococcus sanguis II strains having the accession numbers NCIMB 40104, NCIMB 40105, NCIMB 40106, and NCIMB 40873, the Streptococcus mitis strains having the accession numbers NCIMB 40107, and NCIMB 40874, the Streptococcus oralis strains having the accession numbers NCIMB 40875 and NCIMB 40876, the Streptococcus lactis strain L1A having the accession number NCIMB 40157, and one or more variants thereof having the same or essentially similar effect; and b) one or more viable Lactobacillus strains chosen from the group consisting of the Lactobacillus rhamnosus strain LB21 having the accession number NCIMB 40564, the Lactobacillus plantarum strain LB3 having the accession number DSM 17852, and the Lactobacillus plantarum strain LB7 having the accession number DSM 17853, and one or more variants thereof having the same or essentially similar effect; in at least one pharmaceutically acceptable medium in which said strains maintain their viability, as well as a kit for and a method of prophylaxis and treatment of Staphylococcus induced infections and conditions, and use

Description

TECHNICAL FIELD[0001]The present invention relates to a pharmaceutical preparation for prophylaxis against and treatment of Staphylococcus induced infections and conditions, to a kit therefor, to a method for prophylaxis against and treatment of Staphylococcus induced infections and conditions, and to uses of said pharmaceutical preparation or kit.BACKGROUND OF THE INVENTION[0002]Staphylococcus infections have since long been a widely spread problem around the world, which also gradually has been aggravated due to development of resistance against different antibiotic medicaments used for treatment of Staphylococcus infections.[0003]Staphylococci are spherically formed Gram-positive bacteria that are common in our daily environment. Under a microscope they appear round and form in grape-like clusters. The Staphylococcus genus includes more than thirty species, e.g. Staphylococcus aureus, Staphylococcus epidermidis, and Staphylococcus saprophyticus. Staphylococcus aureus belongs to t...
