“…29 En México, en cepas aisladas de pacientes pediátri-cos durante 1960-1980, la resistencia para la ampicilina se incrementó de 35 a 80%; para la tetraciclina, se mantuvo en más de 90%; para el cloranfenicol, aumentó de 57 a 68%, y para el TMP/SMZ, de 52 a 72%. 38 …”

“…Posteriormente hubo un franco descenso en la resistencia para ampicilina, cloranfenicol y TMP/SMZ (5-10, 5 y 10%, respectivamente), el cual se ha mantenido. 35,38 Salmonella no typhi Entre 1960 y 1987, en un hospital pediátrico de México se encontró que la resistencia de Salmonella incrementó para ampicilina (7 vs 30%) y tetraciclina (26 vs 42%). La resistencia a TMP/SMZ se mantuvo menor a 15%, y al igual que para Shigella, la furazolidona demostró ser un fármaco altamente efectivo.…”

“…La resistencia a TMP/SMZ se mantuvo menor a 15%, y al igual que para Shigella, la furazolidona demostró ser un fármaco altamente efectivo. 38 Sin embargo, en otro centro pediátrico, durante 1982-1985 la resistencia para ampicilina, cloranfenicol y TMP/SMZ fue muy elevada (30-50%), lo que se atribuyó a la existencia de brotes epidémicos en el hospital. 35,38 Salmonella entérica serotipo tiphimurium En años recientes una cepa de Salmonella conocida como tipo 104 (DT 104) ha cobrado importancia debido a su multirresistencia.…”

Los primeros casos se notificaron en el Reino Unido, y durante los últimos cinco años este microrganismo se ha encontrado con frecuencia creciente en EUA.…”

“…Antimicrobial susceptibility test was also performed on some reference strains: E .coli ATCC 35218, S. aureus ATCC 25923,P. aeruginosa ATCC 27853, B. subtilis ATCC 6633, and K. pneumonia ATCC 18833 (7,8). To evaluate the antimicrobial activity, two solutions of the two Lactobacillus strains, L. casei and L. acidophilus were prepared as the following: first, the strains were incubated for 72 h at 37˚C in MRS broth containing 0.2% glucose, and then the broth was centrifuged; and the supernatant was filtered with microbiologic filters to remove any bacterial cells.…”

Background: Probiotics are live microbial supplements which can improve the healthy intestinal microbial balance. Lactobacilli are a group of lactic acid producing bacteria (LAB) that are known as natural probiotics found in the dairy products. Objectives: In this study, we aimed to detect the most potent Lactobacillus isolates of the Fars province local dairy products in cholesterol removal and investigate their antibacterial properties against some gastrointestinal pathogens. Materials and Methods: Fifteen locally produced yogurt samples of the Fars province were collected and characterized with routine microbiology methods. Cholesterol removal ability of the Lactobacilli isolates were determined, and their growth inhibitory effect on some standard pathogenic strains pathogen was evaluated using the well-diffusion method. Results: In this study, five common strains of Lactobacilli including L. acidophilus, L. casei, L. fermentum, L. lactis, and L. bulgaricuswere identified in the samples obtained from the locally produced yogurt in the Fars province. L. lactis and L. acidophilus were determined as the two most active strains with the maximum rate of cholesterol assimilation (5.6 and 4.5 mg/mL, respectively) in the process of cholesterol removal. In the antibacterial activity assay, the two mentioned strains had significant inhibitory effect on all of the tested bacteria except for B. subtilis. Conclusions: Cholesterol removal ability had a direct relation with bacterial growth, so it is suggested to use the probiotic bacteria in the growth phase to achieve better results.
