Beneficial Prokaryote – Pseudomonas putida Pseudomonas putida is a gram negative and non-pathogenic bacterium with rod shape. It is usually grow in soil and water which high in oxygen content at 25-30°C. It has mutlitrichious flagella for mobility and it is sensitive to environment changes. Pseudomonas putida has several important strains which are F1 and KT2440 and a few significant plasmids such as the TOL and OCT plasmid. Besides that‚ it has a circular genome where around eighty genes in

Diversity and Ubiquity of Microbes Pre-Laboratory Questions 1. What environmental settings would you expect to provide rich sources of microbes‚ in terms of overall numbers and different microbial types? Since the most of the microbes are ubiquitous‚ they are readily found in public bathrooms‚ phones‚ countertops‚ door handles‚ kitchen sinks‚ and human body parts such as the face and hands (Sherwood‚ 2017). In addition‚ public places exemplified by hospitals‚ grocery stores‚ and schools present an

MRSA The patient safety problem of interest to me that I have chosen to talk about is MRSA. “MRSA” stands for Methicillin Resistant Staphylococcus Aureus. Staphylococcus Aureus or “Staph Aureus” for short. ( SARI‚ 2007). MRSA is transferred from person to person through a bacteria (germs). Many people carry this germ. It is estimated that one in three people are carriers of this germ (CDC Gov 2013) but it is not always harmful - these people would have it on their skin or in their nose‚ but

provide accurate data. 2. Through this letter I would like to present my opinion regarding Grams staining method and reliability of this method. According to me‚ Grams staining process is a simple technique that assists in recognition of etiological agent and therefore can be called as one of the most significant staining practices in microbiology. Though‚ Gram is concerned that the staining process developed by him is imperfect because not all bacteria can be stained by it‚ but in my opinion

Raudah P. Mangbisa Grade VIII-Nilo VIRUS A virus is a small infectious agent that replicates only inside the living cells of other organisms. Viruses can infect all types of life forms‚ from animals and plants to bacteria and archaea. Characteristics: Like living organisms‚ viruses contain nucleic acids and proteins. Inside living cells‚ viruses can reproduce‚ but not by the process of mitosis like most living cells. Viruses lack some characteristics of living organisms. Outside of living cells‚ viruses are

MRSA in the World Methicillian-resistant Staphylococcus aureus‚ also known as MRSA‚ is any strain of the bacteria S.aureus that has evolved a resistance to beta-lactam antibiotics‚ which includes the penicillin and cephalosporin family. This creates world-wide concern because there aren’t too many antibiotics left to treat S. aureus if the drug evolves greater resistances to stronger antibiotics. MRSA is one of the top leading causes of nosocomial acquired infections. According to an article
