Penicillin was first used in the 1940s to treat gonorrhea infections produced by the bacterium Neisseria gonorrhoeae. In 1984, according to the CDC, fewer than 1% of gonorrhea infections were caused by penicillin-resistant N. gonorrhoeae. By 1990, more than 10% of cases were penicillin resistant and a few years later the level of resistance was 95%.
Explain the various ways this resistance could be spread among the cells. Could this resistance pass to other infectious bacteria from N. gonorrhoeae?
The following are the limitations of Koch's postulates EXCEPT:
A. some pathogens cannot grow on artificial media and therefore cannot be identified as the causative agent
of the disease
B. some diseases involve multiple pathogens which produce similar symptoms making it difficult to pinpoint
the causative agent
C. some diseases are host-specific and re-inoculation may pose ethical concerns
D. some microorganisms are present in the body fluids of the infected animal which make them difficult to be
cultured
Choose one infectious disease from the list below and use the chain of infection to analyze how it is spread.
A. Please provide a comprehensive description of cholera.
B. Describe the chain of infection cholera. The chain of infection for the chosen infectious disease must clearly include the following:
1. Identification of
a) the pathogen,
b) the reservoir
c) means of transmission
d) the susceptible host
2. Describe how one could break the chain of cholera, such as breaking the pathogen link, by providing a specific intervention.
3. Include references and relevant data.

- A suspected pathogen is observed from the blood of a diseased mouse. An investigation of the other mice in the area indicates that it is not present in healthy mice. With Koch's postulates in mind, what is the next step to determine whether or not this suspected pathogen is the cause of disease in the mouse? a) Grow the suspected pathogen in a pure culture Ob) Re-isolate the suspected pathogen and show that it is the same as the original pathogen c) Inoculate a healthy mouse with the suspected pathogen O d) Determine whether the organism in the pure culture is the same one as in the original samplearrow_forwardYou have isolated a beta-lactamase producing Staphylococcus aureus (not a MRSA strain) from an infected surgical site on your patient. If for genetic reasons, your patient is allergic to all antibiotics except beta-lactam antibiotics such as ampicillin ( they can only take Beta-lactam antibiotics such as ampicillin), which strategy below could you use to treat this Staphylococcus aureus infection in your patient? Note different answers compared to previous question. give the patient erythromycin can use a beta-lactamse resistant beta-lactam such as methicillin or oxacillin O give the patient penicillin give the patient an azole drugarrow_forwardAn outbreak of Ebola between 2014 and 2016 resulted in 28,616 cases and 11,310 deaths in Guinea, Liberia and Sierra Leone. An additional 36 cases and 15 deaths were reported outside these 3 countries. This deadly disease urged the need for extensive research on Ebola to better understand and treat the disease and prevent future outbreaks. Ebola is a - SSRNA virus. What does this mean for how it is converted into proteins? Does this virus require additional machinery to be infectious? Can you hypothesize based on how it replicates in the cell what scientists might hope to target for treatment or prevention of Ebola?arrow_forward

- 1) In 2005 a typhoid outbreak in Delmas, South Africa, prompted the widespread testing of food and water sources to ascertain the origin of the outbreak. However, the origin of the outbreak could not be definitely tracesd. What could have been the possible reasons for this state of affairs? 2) A hypothetical culture media is being developed for the isolation of Salmonella Typhimurium. How will these unique characteristics be used to produce a culture media that is both selective and differential for the isolation of presumptive Salmonella Typhimurium?arrow_forwardIdentifying an unknown bacterium is an essential step in the diagnosis and treatment process. Since not every antibiotic is effective against every type of bacteria, knowing what caused a particular infection allows us to make correct prescriptions so patients can recover more quickly. Knowing the cause of an infection also prevents antibiotic resistance as well, since incorrect prescriptions allow bacteria to be unnecessarily be exposed to antibiotics, increasing the chances of developing resistance.arrow_forwardUsing the Koch's Postulates, support the findings that Mycobacterium tuberculosis is the causative agent of tuberculosis. Specifically, you have to provide brief narratives/pictures/proofs and sources that support the postulate listed below: The organism must be isolated from the newly infected animals and cultured again in the laboratory, after which it should be seen to be the same as the original organism.arrow_forward
- Robert Koch developed a set of criteria (postulates) for conclusively demonstrating the aetiology (specific cause) of an infectious disease. Which of the following is not a postulate?

The graph on the right shows the growth curve following addition of lysozyme during the logarithmic phase of bacterial growth. Which statement could account for the data in these graphs? Strain B is wild-type Strep. pneumoniae, and strain A is a mutant that cannot modify its peptidoglycan to be lysozyme-resistant.
