Cell free culture supernatants were obtained by centrifugation (10,000 x g, 4[degrees]C, 20 min) of LAB cultures, and the supernatants were filtered through a 0.22 pm filter to remove residual cells, then, they were examined by the diameters of inhibition zones using agar diffusion assay method (Ennahar et al., 2000) with Salmonella enterica ATCC [43971.sup.T], Escherichia coli ATCC [11775.sup.T] (Gram-negative bacteria) and Micrococcus luteus ATCC [4698.sup.T] (Gram-positive bacteria) as indicator strains.
Ethyl acetate soluble fraction also showed strong activity against Micrococcus luteus ATCC 9341 with MIC=62.5 g/disc.
Foram realizados ainda antibiogramas com a utilizacao de discos de novobiocina (5[micro]g) e polimixina B (300 UI), bem como furazolidona (100 [micro]g) e bacitracina (0,04UI), para diferenciagao entre os generos Micrococcus e Staphylococcus.
Infection was then produced via the inoculation of serial tenfold dilutions of a culture of either Staphylococcus aureus or Micrococcus species into the suprapatellar pouch.
He points out that "widespread antibiotic use for acne and rosacea has been implicated in the conversion of normal cutaneous saprophytes into drug-resistant pathogens." As an example, the author cites the fact that tetracycline-resistant Micrococcus luteus has been implicated as a cause of bacterial endocarditis.

En el hepatopancreas se aislo bacterias de los 15 generos, mientras que en el intestino no se encontro los generos Providencia y Micrococcus. Se encontro diferencias estadisticas en la frecuencia de algunas bacterias aisladas dentro de cada tipo de muestra por efecto del sistema de crianza (Cuadro 1).
