This work aimed to study the metabolic changes after augmentation enterocystoplasty at different lengths of ileum as a tool for treatment of0.230±0.005% respectively.The bacteriological examination of cooking and table butter samplesrevealed that psychrotrophic bacteria could be detected in 78% and 100% ofsamples with a mean value of 4xl04±8x 103 and 5x106±2x105/g respectively.The lipolytic psychrotrophic bacteria were present in 66% and 92% ofexamined cooking and table butter samples, with a mean value of 2x 102 ±8x 10 and 3 x 103 ± 2x 102 respectivelyPseudomonas spp., Bacillus spp., Alcalig-enes, Flavobacterium,Streptococcus and Enterobacteriaceae could be isolated at varyingpercentages from the examined cooking and table butter samples.IStaphylococci and Acientobacter could be isolated form the examinedcooked and table samples respectively. While Acinetobacter spp. wereisolated from table butter samples only.
