analyzed was Staphylococcus epidermidis. This organism is gram-positive‚ single celled‚ arranged in grape-like clusters‚ and cocci in shape (Bukhari‚ 2004). S. epidermidis is approximately 0.5 to 1.5 micrometers in diameter‚ it is a facultative anaerobe but grows best in aerobic conditions (Bukhari‚ 2004). Typical hosts of this species are humans and other warm-blooded animals‚ where a favorable temperature of 37℃ is usually maintained in the intestinal tract. S. epidermidis may cause urinary tract

INTRODUCTION: In this laboratory exercise explore the differences of microorganism and continue our use of specialized media and use some biochemical testing.This report discloses the basic laboratory instruments will be used in each of our practices .It is of great importance to recognize and identify the different instruments and laboratory tools‚ because in this way will we be able to use them properly and also to call them by name and know why.

The ten Petri dishes that exclusively did not contain an antibiotic in the bacteria culture served as the control. There were ten trials for the control and each level of IV. The experiment began by cleaning the work area and sterilizing it with 70% ethanol. Then trypticase soy agar (TSA) was poured into six groups of 60 Petri dishes (See Appendix 1). The dishes were labeled based on the antibiotic used and were left to dry and solidify at room temperature. After an hour‚ the dishes were placed in

Microorganisms that are used to assess the microbial quality of swimming pool and similar environments include heterotrophic plate count – HPC (a general measure of non-specific microbial levels)‚ faecal indicators (such as thermotolerant coliforms‚ E. coli)‚ Pseudomonas aeruginosa‚ Staphylococcus aureus and Legionella spp. HPC

definitely want to know that the compound is effective against the organism(s) you are trying to eliminate. This project shows you one method of measuring the effectiveness of an antimicrobial agent against bacteria grown in culture. This is called the Kirby-Bauer disk-diffusion method‚ and here is how it works. The bacteria of interest are swabbed uniformly across a culture plate. Then a filter-paper disk‚ impregnated with the compound to be tested‚ is placed on the surface of the agar. The compound diffuses

smaller in size and withers. Isotonic environments are preferred by most microbes for the most advantageous growth‚ although some live in slightly hypotonic solutions. (Alonzo‚ 2008) Growth in NaCl Solutions Samples of S. cerevisiae and S. epidermidis were placed into sodium chloride (NaCl) solutions of 1‚ 7 and 15 percent which were supplied in the lab kit. The S. cerevisiae results are as follows. After 24 hours of observation there was a moderate amount of growth in the 1% NaCl solution
