use a systematic battery of tube tests and plates designed to lead to identification of two unknown bacterial species‚ from the combination of all results. A sample of bacteria was used‚ labeled “Sample 4”‚ from which both species was to be obtained‚ one gram positive and one gram negative. Table 1 is a list of the possible bacteria to be identified; the basic ideas and practice of identification of an unknown sample of bacteria are important for a microbiologist to develop.

Double-J (DJ) stenting is the commonest procedure performed in urology. Patients with stent‚ develop stent infections and stent-related symptoms. Use of antibiotics in patients with DJ stent is rampant. No uniform data is there to prove advantage of antibiotic prophylaxis.

Introduction To date‚ the bacterial resistance to antibiotics is one of the most important global health threat introduced by the World Health Organization (WHO) and most annual mortality due to hospital infections occurs because of this challenge (1). According to the US Centers for Disease Control and Prevention (CDC) report‚ carbapenem-resistant Enterobacteriaceae (CRE) are one of the three main antibiotic resistance threats. (2). Enterobacteriaceae are Gram-negative bacilli which cause a wide

Mini-Lab Report Objectives: There were two major goals of the “Observing Bacteria and Blood” experiment. The first was to establish a familiarity with the proper techniques for using a microscope. The experiment focused on both the basic components of a microscope (i.e. how to adjust the knobs and levers for the desired result) as well as how do decide the proper objective to use for observing a specimen. The second goal major goal of this experiment was to practice observing live specimens
