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.
Which of the following is NOT true of bacterial exotoxins? Important in the pathogenesis of many human diseases Their toxic effect can be systemic, affecting cells distant from the primary site of infection None of the other four answers (All are true of bacterial exotoxins) Different exotoxins may affect different types of cells (e.g., nerves, gastrointestinal mucosa) Some exotoxins have two components, A (active) and B (binding)
Normal microbiota: A. are only found in the digestive tract. B. protect us from disease by crowding out "bad" invading bacteria. C.are only found on small select parts of our bodies. D.always cause disease when growing on our bodies. E.play no role in our general health.

Helping tags: Biology, microbiology, outbreak, botulism WILL UPVOTE, just pls help me answer the question. Make up a botulism outbreak scenario which involves a homemade canned food product. DO NOT FORGET to mention the ff: - Food source - Geographic location - Affected population - Symptoms - Chain of events that led to the outbreak
Which of these word parts means “higher”, or “elevated” or “advanced”? Proto- An- Eu- Which of these microbes are the smallest? Mycoplasma Amoeba Rickettsia Which of these types of microbes has the most complex cell? Bacteria Viruses Protozoa A bacteria cell which is longer than it is wide is classified as: Vibrio Coccus Bacillus Bacteria which normal colonize the human gut are classified as: Anaerobes Pathogens Aerobes A bacteria which absolutely needs oxygen to live is classified as: Obligate anaerobe Obligate aerobe Facultative anaerobe The structure on this list which will NOT be found in any bacterial cell is: Cytoplasm Flagella Nucleus The genetic information of bacteria cell is contained in the: Capsid Nucleoid Ribosomes The genetic material of a virion is called the: Genome Nucleoid Nucleus
Exotoxins can be the following EXCEPT: Othey are LPS/lipopolysacharride O they are proteins they are made by bacteria growing in our bodies O they are secreted and act OUTSIDE the bacteria
Infectious diseases can be caused and spread by all manner of living and non living things. Which group of microbes seems to be the worst? Why?
Please help. The terms germ and microbe are often used interchangeably. What comes to mind when you hear the word germ? The word biome can be defined as a major ecological community type such as a grassland or desert. Why is the term microbiome used to describe the microbes that live in or on the human body? Describe the benefits the microbe Bacteroides thetaiotaomicron provides to its host species. Helicobacter pylori was originally identified as a causative agent for ulcers in humans, but turns out its role is more complex. Describe how H. pylori also plays a role in regulating appetite. Describe the role that Bacteroides fragilis plays in controlling the human immune/inflammatory response.
What are the microbes called which colonize our bodies and actually help us to survive by aiding digestion or guarding against infection. vectors normal flora pathogens fomites
There have been recurring cases of mad-cow disease in the United Kingdom since the mid-1990s. Mad-cow disease is caused by a prion, an infectious particle that consists only of protein. In 1986, the media began reporting that cows all over England were dying from a mysterious disease. Initially, there was little interest in determining whether humans could be affected. For 10 years, the British government maintained that this unusual disease could not be transmitted to humans. However, in March 1996, the government did an about-face and announced that bovine spongiform encephalopathy (BSE), commonly known as mad-cow disease, can be transmitted to humans, where it is known as variant Creutzfeldt-Jakob disease (vCJD). As in cows, this disease eats away at the nervous system, destroying the brain and essentially turning it into a spongelike structure filled with holes. Victims experience dementia; confusion; loss of speech, sight, and hearing; convulsions; coma; and finally death. Prion diseases are always fatal, and there is no treatment. Precautionary measures taken in Britain to prevent this disease in humans may have begun too late. Many of the victims contracted it over a decade earlier, when the BSE epidemic began, and the incubation period is long (vCJD has an incubation period of 10 to 40 years). A recent study concluded that 1 in 2,000 people in Great Britain carry the abnormally folded protein that causes vCJD. In spite of these numbers, the death rate from vCJD remains low. It is not clear whether this means that the incubation period for the disease is much longer than previously thought, or whether they may never develop the disease. If you were traveling in Europe, would you eat beef? Give sound reasons why or why not.
