What type of disease is malaria? What is Yersinia pestis? What disease does this microorganism cause? Explain the relationship of this disease to epidemiology throughout history. Describe in detail the pathology of this disease and the organism that causes it. Include how it is typically ...
In 46 patients a single organism was recovered that included coagulase-negative Staphylococci (17 cases), Staphylococcus aureus (13 cases), alpha-hemolytic Streptococcus (seven), Morganella morganii (three cases), Serratia marcescens (two cases), Escherichia coli (two cases), and Enterococcus ...

The most commonly known pathogenic strain of E. coli is Escherichia coli O157:H7, which produces a toxin that can cause severe foodborne illness. This bacteria is usually contracted through contaminated food, water, or person-to-person contact. The symptoms of E. coli infection are similar to ...
The number of genes in all the microbes in one person's microbiome is 200 times the number of genes in the human genome (all of the approximately three billion base pairs of deoxyribonucleic acid (DNA) that make up the entire set of chromosomes of the human organism). The human microbiome...
The RAD6 pathway of budding yeast, Saccharomyces cerevisiae, is responsible for a substantial fraction of this organism's resistance to DNA damage, and also for induced mutagenesis. The pathway appears to incorporate two different recovery processes, both regulated by RAD6. The error-prone recovery...
The intestinal mucosa physiologically contains immune cells much more than other organs and tissues, and this is mainly due to its anatomical configuration and function as the first barrier of the organism[86]. In the “irritated” gut there is an increased population of immune cells in the smal...
The microorganism is a tiny organism that is found on the earth's surface. They include unicellular organisms such as bacteria and archaea. In addition, they also contain multicellular organisms such as fungi and viruses.Answer an...
What is an operon? In what type of organism would you expect to find an operon? Give an example of an inducible operon, describe the overall function of the gene(s) it encodes, and how it is regulated. How is an operon typically organized? Describe a type Why is...
