que constituem a população dominante da flora intestinal e cu ja presença evita geralmente a implantação e desenvolvimento de microorganismos potencialmente patogénicos como por exemplo anterobactérias, pseudomonas, estafilococos, fungos e microorganismos semelhantes. A destruição pelo menos parcial da flora intestinal normalmente dominante pode assim levar ao de^ senvolvimento indesejável de microorganismos infecciosos, que podem ser particularmente perigosos para alguns pacientes.which constitute the dominant population of intestinal flora and whose presence generally avoids the implantation and development of potentially pathogenic microorganisms such as anterobacteria, pseudomonas, staphylococci, fungi and similar microorganisms. The at least partial destruction of the normally dominant intestinal flora can thus lead to the undesirable development of infectious microorganisms, which can be particularly dangerous for some patients.

Foi já proposto administrar simultaneamente várias bactérias ou fungos: contudo, isto foi efectuado apenas para substituir a população microbiana que constitui a flora normalmente existente no intestino e que foi destruída pelo tratamento antibiótico.It has already been proposed to administer several bacteria or fungi simultaneously: however, this was done only to replace the microbial population that constitutes the flora normally existing in the intestine and which has been destroyed by antibiotic treatment.

A presente invenção pretende apresentar novas composições contendo bactérias que se destinam não só à substituição da flora inicial mas também a evitar a destrui, ção da flora intestinal de ocorrência natural.The present invention aims to present new compositions containing bacteria that are intended not only to replace the initial flora but also to prevent the destruction of naturally occurring intestinal flora.

Assim, esta invenção refere-se mais particularmente à preparação de composições terapêuticas de admi nistração oral que contêm bactérias estritamente anaeróbicas, susceptíveis de produzirem -lactamases e reduzirem as acções indesejáveis das -lactaminas na flora intestinal humana, co mo por exemplo :Thus, this invention relates more particularly to the preparation of therapeutic compositions for oral administration which contain strictly anaerobic bacteria, capable of producing β-lactamases and reducing the undesirable actions of β-lactam in the human intestinal flora, such as:

Isolaram-se fezes de indivíduos saudáveis em condições estritamente anaerôbicas. Em cada indivíduo iden tificaram-se os clones dominantes e mediu-se a actividade ^(-lactamase in vitro das estirpes isoladas.Stool was isolated from healthy individuals in strictly anaerobic conditions. In each individual the dominant clones were identified and the β (- lactamase) activity of the isolated strains was measured in vitro.

Detectaram-se as/¾-lactamases por meio de um ensaio microbiológico semi-quantitativo descrito por Rolfe RD e col. (J. Infect. Dis. 147, 227, 1983). Mede-se a actividade numa escala arbitrária de 0+ a 4+. A actividade máxima de-lactamase é classificada como 4+. As actividades intermédias classificadas como 3+, 2+, 1+ correspondem a uma hidrólise parcial do antibiótico. 0+ é considerado como an sência de actividade^-lactamase. Utilizaram-se neste ensaio o Meio Gelose 5 (Difco ) e a estirpe de controlo B. subtilis ATCC6633./ ¾-lactamases were detected by means of a semi-quantitative microbiological assay described by Rolfe RD et al. (J. Infect. Dis. 147, 227, 1983). Activity is measured on an arbitrary scale from 0+ to 4+. Maximum de-lactamase activity is rated 4+. Intermediate activities classified as 3+, 2+, 1+ correspond to a partial hydrolysis of the antibiotic. 0+ is considered as an absence of β-lactamase activity. Medium Gelose 5 (Difco) and the control strain B. subtilis ATCC6633 were used in this assay.

Incubaram-se as amostras fecais durante 30 minutos a 37QC com uma concentração antibiótica perfeitamente conhecida :Fecal samples were incubated for 30 minutes at 37 ° C with a well-known antibiotic concentration:

a) Associação de quatro estirpes anaeróbicas produtorasde β -lactamase e tratamento por ceftriaxona :a) Association of four anaerobic strains producing β-lactamase and treatment with ceftriaxone:

Guardam-se ratos sem germes (axénicos) C3H (Centre de Selection des Animaux de Laboratoires, Orléans, França), num isolador de plástico flexível. Como bebida, eles bebem apenas água esterilizada pelo calor a pH 3. 0 alimento é um produto comercialmente disponível (R03, Villemoisson/Orge, França) esterilizado por irradiação a 4 megarad.C3H (axenic) germ-free mice (Center de Selection des Animaux de Laboratoires, Orléans, France) are stored in a flexible plastic insulator. As a beverage, they drink only water sterilized by heat at pH 3. The food is a commercially available product (R03, Villemoisson / Orge, France) sterilized by irradiation at 4 megarad.

A estes ratos estão associados três estirpes de bacteróides e um de clostridium :These rats are associated with three strains of bacteroids and one of clostridium:

- Cl : - Cl: B. B. thetaiotaomicron thetaiotaomicron - C6 : - C6: C. Ç. clostridiformis clostridiformis - E9 : - E9: B. B. uniformis uniforms - V4E3 - V4E3 B. thetaiotaomicron B. thetaiotaomicron

Antes do tratamento por ceftriaxona, não se encontra uma actividadey^)-lactamase (0+) enquanto se pode observar uma implatação de estirpes bacterianas a 1(ίΧθ’ — — 0’3X)ufg/g de fezes. Quando os mesmos ratos recebsn ceftriaxona per os (adicionada a água a uma dose de 2 mg/ml), as contagens totais não são modificadas e não se detecta actividade enzima tica mas o antibiótico não ê detectável nas fezes.Before treatment with ceftriaxone, there is no activity ^ ^ - lactamase (0+) while an implantation of bacterial strains at 1 (ί Χ θ '- - 0' 3X ) ufg / g of feces can be observed. When the same rats receive ceftriaxone per os (water is added at a dose of 2 mg / ml), the total counts are not modified and no enzyme activity is detected but the antibiotic is not detectable in the stool.

b) Acção da introdução de estirpes produtoras àe. β-lactamases de anaeróbios em ratos com uma flora intestinal humana e tratados por ceftriaxona :b) Action for the introduction of strains producing ae. Anaerobic β-lactamases in rats with human intestinal flora and treated with ceftriaxone:

Associaram-se também ratos axénicos a uma flora humana complexa. A preparação da solução alimentar é fei. ta numa câmara anaeróbica a partir de fezes humanas recente mente recolhidas. Moi-se a amostra, dilui-se 100 vezes em meio LCY e coloca-se a preparação no isolador contendo os ratos axé nicos. Para evitar qualquer contacto desta solução bacteriana com oxigénio, utilizam-se tubos hermeticamente fechados para colocar a mesma na câmara anaeróbica. Tal como efectuado anteriormente, os ratos previamente submetidos a jejum hídrico fo ram alimentados por via gástrica e rectal.Axenic rats were also associated with a complex human flora. The preparation of the food solution is done. in an anaerobic chamber from human feces recently collected. The sample is ground, diluted 100 times in LCY medium and the preparation is placed in the isolator containing the axonic rats. To avoid any contact of this bacterial solution with oxygen, hermetically sealed tubes are used to place it in the anaerobic chamber. As previously performed, the rats previously subjected to water fasting were fed gastric and rectally.

Repete-se a alimentação após 24 horas. São necessários dez a quinze dias para se obter o equilíbrio intestinal com efeitos de barreira semelhantes aos encontrados no homem.Feeding is repeated after 24 hours. It takes ten to fifteen days to achieve intestinal balance with barrier effects similar to those found in man.

Inoculam-se ratos associados com flora humana intragastricamente com 1 ml de caldo TGY (Tripticase 30 g/1, extracto de fungo 20 g/1, glicose 5 g/1, tioglicolato de sódio 1 g/1, pH = 7,4) contendo 5x10 cfu/ml de 4 estirpes productoras ά&β-lactamase (Cl, C6, E9, V4E3) imediatamente antes da administração oral de Ceftriaxona (2 mg/ml na água de beber). Apresentam-se os resultados obtidos na tabela III.Rats associated with human flora are inoculated intragastrically with 1 ml of TGY broth (Tripticase 30 g / 1, fungus extract 20 g / 1, glucose 5 g / 1, sodium thioglycolate 1 g / 1, pH = 7.4) containing 5x10 cfu / ml of 4 ά & β-lactamase producing strains (Cl, C6, E9, V4E3) immediately before oral administration of Ceftriaxone (2 mg / ml in drinking water). The results obtained are shown in table III.

Durante o tratamento, não se encontra concentração de antibiótico nas fezes. Encontra-se actividadefy-lactamase contra ceftriaxona após 14 dias de tratamento (compreendida entre 1+ e 4+).During treatment, there is no concentration of antibiotics in the stool. Fy-lactamase activity against ceftriaxone is found after 14 days of treatment (between 1+ and 4+).

As enterobactérias susceptíveis à ceftria zona são eliminadas. As contagens de enterococos são equivalen tes às encontradas em controlos não tratados, Mantem-se a resistência a uma colonização por microorganismos exógenos resis tentes ã ceftriaxona (Ent. cloacae IGR67, C. albicans IGR66) em ratos em que se introduziram previamente estirpes bacteróides.Enterobacteria susceptible to the cephatric zone are eliminated. Enterococcal counts are equivalent to those found in untreated controls. Resistance to colonization by exogenous microorganisms resistant to ceftriaxone (Ent. Cloacae IGR67, C. albicans IGR66) is maintained in rats in which bacteroid strains were previously introduced.

As bactérias anaeróbicas estão ainda presentes no grupo que recebeu bacteróides e as contagens totais obtidas em camara anaeróbica não são significativamente modifi cadas pela presença destas bactérias, quando comparadas com os controlos. Os valores de MIC 50 e 90 destas bactérias são respectivamente de 512 e acima de 1024 yig de ceftriaxona por ml.' Os bacilos gram negativos perfazem 84 Ί desta flora e existem também 13 % de bacilos gram positivos esporulados e 3 aL de cocos.Anaerobic bacteria are still present in the group that received bacteroids and the total counts obtained in anaerobic chamber are not significantly modified by the presence of these bacteria, when compared to controls. The MIC 50 and 90 values of these bacteria are 512 and above 1024 yig of ceftriaxone per ml respectively. ' Gram negative bacilli make up 84 Ί of this flora and there are also 13% sporulated gram positive bacilli and 3 to L of coconuts.
