Summary Introduction
To review:
The experimental design for the analysis of digestive tract of the newborn chicks, in such a way to eliminate the possibility of salmmonella infection in digestive tract of newborn chicks.
Introduction:
The gut microbial community and integrity of the gastrointestinal tract (GIT) play important roles in absorption of nutrients, immunity development and resistance from the disease. The changes in the microbial community of chicken may leads to the adverse effects on productivity, feed efficiency and health of the chicken. Thus the microbiome research is essential for the improvement of poultry GI microbiome.

Assume you work at the local hospital in your home town. Suddenly you notice that 10% of your patients are having serious staphylococcal infections. None of these patients were admitted for having a staphylococcal infection, and we assume that all standard infectious control procedures are being followed (hand washing, use of gloves and masks, etc.). Remember that a small percentage of bacteria do evade even the most scrupulous of infectious disease control procedures. How could you use what you have learned in this week’s laboratory to solve the problem?
How could you find out where the infection originated? What steps would you need to take?
How could you determine definitively what organism is causing these patients’ infections?
How could you determine how to treat these patients?
Once you determine the source of the infection, what ethical issues, if any, are involved here? What should you do to protect the privacy and welfare of the patients as well as avoiding conduct…

He noticed that a mold called Penicillium was also growing in some of the dishes. A clear area existed around the mold because all the bacteria that had grown in this area had died. In the culture dishes without the mold, no clear areas were present. Fleming hypothesized that the mold must be producing a chemical that killed the bacteria. He decided to isolate this substance and test it to see if it would kill bacteria. Fleming transferred the mold to a nutrient broth solution. This solution contained all the materials the mold needed to grow. After the mold grew, he removed it from the nutrient broth. Fleming then added the nutrient broth in which the mold had grown to a culture of bacteria. He observed that the bacteria died which was later used to develop antibiotics used to treat a variety of diseases. (Biology Corner) 1. What was the initial observation Fleming made? 2. What was…arrow_forward
- Describe one scenario in which antibiotic resistant bacteria in a chicken could enter your body.arrow_forwardWhy must the top agar be supplemented with maltose? A) Maltose allows for binding of the phage to the E. Coli and aids in the infection process B) Maltose helps stabilize the phage within the mediaarrow_forwardA 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_forward
- Micro -endotoxin refers to which type of molecule found in (unique to) gram negative bacteria ..... ( it is not lipopolysaccharide)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_forwardNote that it is not appropriate to self-diagnose outside of a medical context and this is a completely hypothetical scenario. Imagine you have a rash on your foot. You're concerned that it's an infection and inoculate a sample onto an agar plate. You wonder, How can I figure out whether the pathogen is a bacterium vs a eukaryote? You decide to use lab supplies to get a basic understanding of the pathogen. Be specific about what tests you use and what you expect the results to be. Limit yourself to experiments we could do in our lab. What is one experiment you could do, involving culturing the organism?arrow_forward
