Why are tumor cells preferred? 2. Why are non-enveloped viruses generally more resistant to disinfectants than are enveloped viruses? 3. A public health physician isolated large number of phages from rivers used as a source of drinking water in western Africa. They physician is very concerned that humans might become ill from drinking this water, although she knows that the phages specifically attack bacteria. Why is she concerned?

An 83 year old patient has been ill the past couple of days with an upper respiratory infection. Her temperature has been elevated at 99.5 °F. Her daughter took her to the physician because of the patient's increasing shortness of breath, fatigue, and lack of appetite. The physician diagnosed a community acquired viral pneumonia and prescribed a 10 day days antibiotics regime.  The daughter asked the office nurse, Why is my mother being put on antibiotics if she has a virus? I thought antibiotics did not work for a virus.  How would the nurse explain this to the patient and her daughter

Microbiota In healthy humans, the internal organs and tissues such as muscles, the brain, and blood do not contain microorganisms. However, surface tissues, such as the skin and mucous membranes, are in continuous contact with environmental microbes and become readily colonized by specific bacteria. The population of microbes regularly found in the body is referred to as the normal microbiota. The term transient microbiota refers to members of the normal microbiota that are present for only a short time before disappearing. A person's normal microbiota is an important part of the immune system, as the normal microbiota often inhibit pathogenic microbes from colonizing the host, a process called microbial antagonism. Different types of bacteria will colonize different niches in a person's body due to variations in moisture level, pH. atmospheric pressure, oxygen levels, and body secretions. Accordingly, different types of medila must be used to culture the various human microbiota. If…

1) Match the antibiotics with their mechanism of action: mechnism of action: 1) nucleic acid synthesis inhibitor 2) Cell wall synthesis inhibitor 3) cell membrane disruptor 4) protein synthesis inhibitor 5) folic acid synthesis inhibitor

Which of the following is NOT a true statement about microbial infections and disease?   1. Some infections are caused by normal microbiota acting as opportunistic pathogens 2. For some infections, a portion of infected people may never develop any signs or symptoms of disease  3. The time between the effective exposure and appearance of the very first signs or symptoms is called the incubation period 4. None of the other four answers (All are true statements) 5. All infectious diseases are communicable; i.e., they can be transmitted between hosts

Normal microbiota provide protection from infection in each of the following ways EXCEPT:   Question 3 options:   A)  they produce antibacterial chemicals.   B)  they compete with pathogens for nutrients.   C)  they make the chemical environment unsuitable for nonresident bacteria.   D)  they produce lysozyme.

Mention microbial infections and most people think of hospitals, not summer camp. But being outdoors in the sunshine and fresh air is not without risk. In June 2012, a camp counselor in Omaha, Nebraska, was diagnosed with histoplasmosis, a fungal infection with symptoms similar to pneumonia: fever, headache, and respiratory distress. Although most people suffering from histoplasmosis will recover without medical treatment, the very young, very old, and people with chronic lung conditions are at greater risk for developing severe disease, which may on rare occasions prove fatal. In areas of the eastern and central United States, where Histoplasma capsulatum is endemic, dirt contaminated with bird and bat guano often contains spores of the fungus. Disturbing such contaminated dirt is a known risk factor for developing the disease. Because the sick camp counselor was one of 32 that worked at the camp, and the camp served 797 children, the Douglas County Department of Health (DCDH) and the…

Q2) In general, humans are free from microbes in utero. Throughout the period of growing up, a healthy individual body can maintain a balanced coexistence of microbial population. (a) Describe the primary roles of microbes in protecting and stabilizing body surface. (b) Discuss how the imbalance and instability of microbes in the body can occur.

Where do - ss RNA viruses assemble? O 1) golgi O 2) nucleus O3) cytoplasm O 4) both the nucleus and cytoplasm O 5) Endoplasmic reticulum Type:S

Which statements are true? Explain why or why not.1 Our adult bodies harbor about 10 times moremicrobial cells than human cells.2 The microbiomes from healthy humans are allvery similar.3 Pathogens must enter host cells to cause disease.4 Viruses replicate their genomes in the nucleus ofthe host cell.5 You should not take antibiotics for diseases causedby viruses.

Select all the statements that are true regarding the drug treatments available for infectious diseases.□ Antiviral drugs are harder to develop than antibiotics because viruses must use our cellular machinery replicate. □ Very few anti-parasitic drugs exist because diseases caused by Eukaryotes are extremely rare all over the world.□ Fewer drugs are available to treat Eukaryotic pathogens because their physiology and functions are very similar to our own.□ Development of antiparasitic drugs are a low priority because the diseases they treat tend to occur in poor countries, and drug companies can't make money.□ Antivirals may quit working because rates of viral mutation are very high.□ There are more antiviral drugs than atibiotics because antiviral drugs are very easy and cheap to make.
