Isolated and Identification of Some Isolated Bacterium from Human in Egypt

Abstract

Microbes are an often overlooked part of an ecosystem because of their small size and lack of morphological characters; however their presence is vital for every kind of known life. The human microflora is an essential and play very important role in health and disease. This study was done for isolates and identifies some samples from deferent section in the human body from Egypt. Twenty samples were collected as following: Five saliva samples of 3 children school volunteers aged (4-10 years) were collected from 3 schools in Alexandria Governorate, Egypt and 2 adult samples aged (22,30 years) were collected randomly. Five feces samples of infant babies aged (3-6 months).Ten teeth samples were collected from adult teeth roots. From our results 42 predominant colonies morphology isolated on MRS agar, BHI agar, MSA and SF agar from 12, 16 and 14 samples of saliva, teeth and faeces respectively. This found to be 24 cocci cells, 14 rods cells and 4 yeasts cells. These bacteria were identified as: 1 Staph.lentus; 5 Staph.xylosus; 1 B. brevis; 3 Lactobacillus acidophilus; 2 Lactobacillus plantarum; 8 Bacillus sp. and 18 Ec.faecalis
