“…Production of antagonistic substances (organic acids, hydrogen peroxide or bacteriocins) against pathogens is a technique that is widely used (McLean & Rosenstein, 2000;Aroutcheva et al, 2001;Strus et al, 2002). Among 134 vaginal Lactobacillus strains isolated previously in our laboratory (Ocaña et al, 1999a), only six strains were able to inhibit all the pathogens under study, except for C. albicans.…”

Lactic acid-producing lactobacilli were selected from 134 human vaginal isolates by testing their capability to inhibit the growth of different pathogenic micro-organisms. Lactobacillus acidophilus CRL 1259 (from the CERELA Culture Collection) was selected to study the effects of temperature, pH and culture medium on growth and lactic acid production. Growth parameters were estimated by using the model of Gompertz. Kinetics of inhibition of uropathogenic Escherichia coli were evaluated in mixed cultures of the pathogen and L. acidophilus. Optimal conditions for growth and lactic acid production by L. acidophilus were pH 6 . 5 or 8 . 0 and 37 8C. Under these conditions, growth was higher in LAPTg (yeast extract/peptone/tryptone/Tween 80/glucose) broth than in MRS (De ManRogosa-Sharpe) broth. However, lactic acid production was more efficient in MRS broth. Under optimal conditions for lactic acid production, L. acidophilus inhibited the growth of E. coli. These results suggest that inclusion of L. acidophilus CRL 1259 in probiotic products for vaginal application would be beneficial.

“…To elucidate whether the antimicrobial activity derives from the production of hydrogen peroxide by LAB, each LAB with antimicrobial activity was evaluated with the hydrogen peroxide test (McLean and Rosenstein 2000). MRS agar supplemented with 0.25 mg/ml of tetramethylbenzidine (TMB, Sigma) and 0.01 mg/ml of horseradish peroxidase (HRP, Sigma) was inoculated with LAB and incubated anaerobically for 48 h at 37ºC.…”

RESUMENLos probióticos se definen como microorganismos que, administrados en cantidades adecuadas, brindan un beneficio en la salud del huésped. El efecto del tratamiento con probióticos viene siendo estudiado extensamente en una diversidad de indicaciones sistémicas y desórdenes médicos. Recientemente existe un gran interés en el control probiótico contra las infecciones orales más comunes como la caries dental y la periodontitis, sin embargo, la información disponible sobre los efectos de probióticos en la salud periodontal y sus condiciones clínicas es aún limitada. La presente revisión describe el conocimiento actual en bacterioterapia con probióticos desde una perspectiva en la salud oral y periodontal. Rev. Clin. Periodoncia Implantol. Rehabil. Oral Vol. 3(3); 136-139, 2010.Palabras clave: Probióticos, salud periodontal, bacterioterapia, terapia de reemplazo. ABSTRACTProbiotics are defined as live microorganisms that administered in adequate amounts, bring beneficial effect on the health of the host. The effect of probiotic therapy has been studied extensively for a variety of systemic indications and medical disorders. Recently, there has been increasing interest in probiotic for the control of the most common oral infectious diseases such as dental caries and periodontitis. However, only limited information is available regarding the effect of probiotics on periodontal health and clinical conditions. This review describes current knowledge on probiotic bacteriotherapy from the oral health and periodontal perspective. INTRODUCCIÓNLa resistencia antibiótica con la emergencia de cepas multiresistentes es un problema global que va en aumento; este desarrollo lamentable ha llevado a los científicos a buscar otras formas de combatir las enfermedades infecciosas (1,2) . Un nuevo método, el enfoque probiótico, es investigado con respecto a la eliminación de los microorganismos patogénicos. Los probióticos son microorganismos vivos, los cuales, administrados en cantidades adecuadas, brindan un beneficio en la salud del huésped (3) . Las bacterias probióticas pueden ocasionar beneficios en la salud del huésped brindándole nutrientes y cofactores, compitiendo directamente con los patógenos, interactuando con los factores de virulencia de éstos y estimulando la respuesta inmune del huésped (4) . El efecto del tratamiento con probióticos ha sido estudiado extensamente para una diversidad de indicaciones sistémicas y desórdenes médicos. Por ejemplo, los beneficios potenciales de los probióticos han sido estudiados en desórdenes gastrointestinales (4,6) , ginecológicos y eczema ectópico (7,8) . Recientemente hay un interés creciente en el control probiótico contra las infecciones orales.Las infecciones orales constituyen las formas más comunes de las infecciones en humanos (9) . La cavidad oral es un ecosistema complejo en el cual se desarrolla una microbiota diversa. El amplio rango de pH, la disponibilidad de nutrientes, las superficies deslizantes y no deslizantes, la saliva, los fluidos creviculares y las comunid...
