We went through intricate aseptic techniques for preparing microbial cultures from the commensal population of microbes in the GI tract isolated from the diabetic and normal rats for recording their count from the extent of lactate, acetate, and glucose production based on four kinds of bacteria, Staphylococcus aureus, Enterobacteriaceae sp, Lactobacillus sp, and Enterococcus sp. The basic kinds of agar displays that were used included, Mannitol Salt Agar for Staphylococcus aureus, MacConkey Agar for Enterobacteriaceae sp, Slanetz & Bartley agar for Enterococcus sp and MRS Agar for Lactobacillus sp. Subsequently we observed the commensal microbial growth in 4 and 8 week diabetic rats along with that in normal rats for obtaining comparative figures through a number of confirmation tests including Catalase test, Coagulase Test, RAPIDEC Staph Test, Oxidase test and API 20E Test. Significant findings showed that the diabetic rats weighed more than the normal rats. The stool of the Ileum and colon of normal and diabetic rats were sent to investigate the microbial aberrancies, after the induction of streptozotocin. Consequently there was an incidental increase in GI tract microbes. The results showed that diabetes in rats were caused 3 days after streptozotocin.
Type 1 Diabetes (T1D)is a condition where the level of blood glucose rises due to absence of insulin. ...

Summary

In the present study, we have sought to investigate variation of the GI tract microbiota in diabetic condition. The GI tract shelters a community of microbes, which help in maintaining the overall physiological health in mammals. Seven normal rats and five diabetic rats were used in the experiments…

Results indicate the overall standard in terms of hygiene of food processing and the food chain. The microbial levels permitted for food to be determined safe are regulated by law. The study is carried out in three stages performed as three experiments. In the first experiment, aerobic plate count is done for E.coli count and coliform count on given food item (Roberts, D, 2003, Gilbert et al, 2000). It is evident that coliforms and E.coli are present in human faeces. Their presence in food items can indicate post processing contamination. The aerobic count is used to determine the overall...

(Institute of Materials, Great Britain, P. 223) The importance is far reaching, from environmental O2 /CO2 balance to the synthesis of artificial herbicides that act on unwanted herbs by blocking some important steps in this energy producing process. The chlorophyll pigment alone has lead to new avenues for thoughts and research on the importance of photosynthetic processes and has paved the way for the synthesis of certain medicinal drugs exploiting its photoprotective mechanisms for preventing light induced damage of cells. The chlorophyll research has added to the significance of this novel...

Antibiotic Sensitivity Testing
The principle of the disc diffusion method is that when a filter disc is impregnated with a chemical that is placed on the agar, the chemical in the agar diffuses around the disc. The solubility of the chemical and its molecular size determines the size of the area if chemical infiltration around the disc. When an organism is placed on the agar around the disc, if it is susceptible to the chemical then there would be no growth around the area where the chemical is diffused and this area is called as the "zone o the inhibition"....
