Bacteria are those organisms which are single cell and they are not seen through naked eye they are only seen when microscope is used. The shape and size of bacteria are different and are measured in micrometer. Healthy humans are the reservoir and source of production of Shiga toxin producing Escherichia coli. The objective of this work is to define more precisely the role of traditional food ingredients in promoting the growth of acid resistant Coli form bacteria in human beings. Different food samples of Yogurt, Dahi bhallay and Fruit chart were taken in measured quantity in sterilized...

Synthetic insecticides has long been involved in causing fetal diseases to human beings as well as cattle. Importance of biological control of insect pests is aan environment friendly approach. With advances in biotechnology, recombinant bacteria and other organisms are being developed for better control of insect pests. Bacillus thuringiensis (BT) holds a central place among biocontrol agents. BT produces parasporal crystal proteins (Cry toxin) during sporulation phase of its growth. These toxins have defined spectra of toxicity to the target insects only, without doing any harm to friend...
