Introduction In this lab experiment our group was given four different types of synthetic blood samples‚ along with three types of synthetic anti- A‚ B‚ and Rh‚ to help identify the ABO-Rh blood types. Its purpose of this experiment is to learn about the form and functions of the bloods components‚ as well as to examine and identify different blood types‚ as many already do so and apply it to real life events‚ whether its through forensics‚ crime scene investigations or at hospitals to help identify

In the 1940s antibiotics were widely introduced as a cure for common types of diseases. However‚ some of the diseases started to build up a resistance to the antibiotics and in result‚ the antibiotics became ineffective. In order to help resolve the crisis‚ antibiotics were found through screenings of soil microorganisms. However‚ soil microorganism’s antibiotics were depleted by the 1960s and their antibiotic effects were unable to be replicated through synthesis. In this experiment‚ the researchers

Where does it come from? (source? Natural or chemical) Streptokinase is extracellular bacterial protein and it comes from purified strains of group C beta-hemolytic streptococcus. It hydrolyzes peptide bonds and has a non-protease plasminogen activator which activates plasminogen to plasmin. This enzyme is used through its lysine binding site which is used as a medical drug for patients with blood clots. It was originally discovered from a precipitate of salt‚ that was then purified so the active

A. The typical human mouth contains a writhing orgy of bacteria. Most of these. Most of these microscopic organisms are bengin‚ and some are even beneficial‚ but one particular variety is a conspicuous troublemaker: Streptococcus mutans. These ubiquitous bacteria thrive on sugars in the mouth‚ which they consume while excreting lactic acid. This acid is responsible for the great majority of tooth decay in humankind because it erodes the enamel and dentin of the teeth. B. A Florida-based company

CHAPTER I INTRODUCTION 1. ENTEROCOCCUS FAECALIS AND STAPHYLOCOCCUS AUREUS OUTLINE The Human indigenous micro flora consists of opportunistic pathogens along with other nonpathogenic bacterial strains. Two eloquent members of the category of gram- positive bacteria‚ Enterococcus faecalis and Staphylococcus aureus belong to this category. Being a facultative anaerobe‚ aero tolerant anaerobe respectively‚ both of these organisms inhabited the human body for centuries. Ability to thrive in extreme condition

Bonnie Bassler claims that bacteria although simple have complex systems that they use to communicate with each other to coordinate. This is crucial to humans because Dr. Bassler considers humans to be 90-99% bacterial. Dr. Bassler states we have about one trillion human cells but we have about 10 trillion bacterial cells that either live in or on humans. The number of bacterial genes in those cells outnumber humans by 100 times since humans only have 30‚000 genes. These bacteria share a mutualistic
