The range also now includes Oxoid Violet Red Bile Lactose (VRBL) Agar (ISO), for the detection and enumeration of coliforms in food, animal feed and environmental samples, and Oxoid Violet Red Bile Glucose (VRBG
) Agar (ISO), for the detection and enumeration of Enterobacteriaceae in food, animal feed and environmental samples.
coli, plates with TBX medium, incubated at 44[degrees]C for 18 h; for Enterobacteriaceae, plates with VRBG
medium, incubated at 37[degrees]C for 24 h; for Enterococcus spp., plates with Slanetz-Bartley medium, incubated at 37[degrees]C for 48 h; for Staphylococcus spp., plates with Baird Parker medium, incubated at 37[degrees]C for 48 h; and for yeasts, plates with Sabouraud dextrose medium with chloramphenicol, incubated at 25[degrees]C for 5 days.
Nesta pesquisa, foram obtidos resultados positivos com r=0,83 de concordancia entre o Petrifilm[TM] EB e a metodologia convencional para enterobacterias em swab de carcaca suina, concordando com o estudo feito por SILBERNAGEL & LINDBERGER (2002), no qual o Petrifilm[TM] EB foi mais sensivel e seletivo, se comparado a sensibilidade do metodo convencional em placa com agar Violeta Vermelho Bile Glicose (VRBG
They were placed in a sterile plastic container waiting for culturing and measuring of total aerobic plate counts using PCA and coliforms using VRBG
. The tomato was ground through a sterile lab grinding machine.
sakazakii from infant formula: pre-enrichment in sterile water and enrichment in EE Broth is followed by plating onto VRBG
Agar, then sub culture onto Tryptone Soya Agar.
