Anna Anderson PTLW CSUEB July 2011 Activity 1.1.2 MICROBIOLOGIST * Microbiologist Microbiologists study microscopic bacteria, fungi, protists, and viruses. Many of these organisms cause disease (pathogens) and many can provide useful products such as penicillin (antibiotic). * Education and/or Training Required In order to work in this field you must have at least an undergraduate degree in microbiology. Further training with a Masters or Doctorate would be required to do anything

In 1952, Martha Chase and Alfred Hershey were able to prove that DNA is the genetic material of the phage T2. The T2 phage consists almost entirely of DNA and protein, it also attacks E. Coli (, a common intestinal bacteria of mammals). The T2 phage quickly turns an E. coli cell into a T2-producing factory that releases phages whenever the cell ruptures. To determine what the source of the genetic material is in the phage, Hershey and Chase designed an experiment in which they labeled the protein

Prevention and Control of Nosocomial Infections A Nosocomial Infection is a very distinct infection that occurs in hospital environments. The work nosocomial literally means – of or relating to a hospital. Also known as hospital-acquired infections (or HAI) these occur in unsanitary or unclean hospital environments and can be contracted by hospital staff, hospital patients and visitors. Infections can be generally described as bacterial or fungal. Nosocomial infections will often cause urinary

Shannon Roberts Bio 101 Self-Study Quiz: What Can We Do About Antibiotic-resistant Bacteria? You Decide What Can We Do About Antibiotic-resistant Bacteria? Summarize, evaluate, and argue the validity of the data that demonstrate the problem of antibiotic-resistant bacteria. Then present a plan for reducing this problem in the future. Keep these questions in mind: · What data supports the hypothesis that antibiotic-resistance is on the rise? What problems do you see in this data? Can you

numerous lives since the innovation of penicillin antibiotics in 1928 by Alexander Fleming. Although, now there is a increasing anxiety that overuse of antibiotics can direct to avoidable side effects and the expansion of drugs which are mostly opposing bacteria such as MRSA (methicillin-resistant Staphylococcus aureus). MRSA has happened to be the most frequent organism responsible for skin, soft tissue and surgical-site infections in the United States and in different parts of the Europe. Different findings

poisoning caused by the Salmonella bacterium. It results in the swelling of the lining of the stomach and intestines (gastroenteritis)” (Carson-De Witt 1). Some of the foods that often contain this bacteria include rare chicken, raw eggs, and unpasteurized milk. Eggs can become infected by the bacteria by sitting on a surface contaminated with Salmonella (Carson-De Witt 2). Salmonella can also be spread by making contact with people or animals infected with this illness. It can

Tissue: epithelial (avascular no blood vessels), connective (may be solid or liquid, cartilage bone, fat tissue, blood, lymph), Neural tissue, muscle tissue (allow movement, keep joint stable, postural control, produce heat) Three types: skeletal: voluntary control, striated; smooth: involuntary, non-strated; cardiac: involuntary, striated. Epithelial: simple, stratified, squamous, cuboidal , columnar. 1.Simple squamous epithelium: mesothelia lining ventral body cavities; endothelia lining heart

resistance happens when bacteria change to protect themselves from an antibiotic. They are then no longer sensitive to that antibiotic. When this happens, antibiotics that previously would have killed the bacteria, or stopped them from multiplying, no longer work. What are ‘superbugs’? ‘Superbugs’ are bacteria that are resistant to several different antibiotics. The methicillin resistant Staphylococcus aureus (MRSA) bacteria commonly found in hospitals, and the bacteria that cause tuberculosis

liquid water or even a tiny amount of moisture, including hot springs on the ocean floor, on human skin, deep inside rocks within the earth, in a cow’s stomach, and inside a sponge used for washing dishes. Microbes can be bacteria, archaea, fungi, or protists, but not prions and viruses, which are classified as non-living. Microbes are usually described as unicellular, or single-celled, organisms. However, some multicellular species are microscopic, and some unicellular protists are visible to the human
