RESUMEN
Se evaluó la actividad antimicrobiana de seis diferentes bacterias cido lácticas sobre Escherichia coli, Salmonella enteritidis y Shigella dysenteriae, bacterias patógenas del tracto gastrointestinal. Los ensayos determinaron que todas ellas presentaron acción antimicrobiana sobre las bacterias entéricas, destacando Lactobacillus fermentum, quien produjo un efecto bactericida.
The antimicrobial activity of six different lactic acid bacteria was evaluated on Escherichia coli, Salmonella enteritidis and Shigella dysenteriae, pathogenic bacteria of the gastrointestinal tract. Tests determined that all of them presented antimicro bial action on the enteric bacteria, especially Lactobacillus fermentum, that generated a bactericidal effect.

Se demostró la infección natural y experimental de los caracoles limneídos peruanos con estadios larvales de Fasciola hepatica. Los índices de infección natural y experimental fueron del 12% y 28% en Lymnaea columella y del 27% y 70% en Lymnaea viatrix, respectivamente. Lymnaea diaphana y Lymnaea cousini no presentaron infección natural y demostraron no ser susceptibles a la infección experimental.
The natural and experimental infection of Peruvian lymnaeid snails with larval stages of Fasciola hepatica was demonstrated. The index of natural and experimental infection was of 12% and 28% in Lymnaea columella and of 27% and 70% in Lymnaea viatrix, respectively. Lymnaea diaphana and Lymnaea cousini did not present natural infection and demonstrated not to be prone to experimental infection.
