To determine:
The way in which Julie and then Jason likely infected.
Case summary:
Julie was surprised and feels very proud that her boyfriend bought her a tattoo as an 18th birthday gift. After, a week Julie and Jason affected by an evolving disease, which is referred to as community associated, methicillin-resistant Staphylococcus aureus (CA-MRSA) diseases. Julie’s leg and arm layered with swollen, red, and painful lesions, (containing pus) soon she developed fever. Jason misunderstood that he suffered by spider bite (Wednesday). On the next day, he unable to walk, and he noticed that a red colour line going up from his ankle to groin. Soon, his health condition became worse and he hospitalized for 10 days.
He severely affected by bacteremia (blood) and osteomyelitis (his bones affected). Around many years, the health centre workers fought to control the healthcare-associated MRSA (HA-MRSA). Usually, the HA-MRSA infects hospitalized patients, but recent year’s common people other than hospitalized patients are also affected such as risky tattooists, school students, and athletes by sharing clothes, fomites, razors, and towels.
Julie is suggested oral antimicrobials such as doxycycline, trimethoprim-sulfamethoxazole, and clindamycin) and she has given vancomycin (intravenous).
To determine:
The reason that why CA-MRSA considered an “emerging disease”.

- You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb? Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.arrow_forwardDesign a grafting experiment to determine if limb mesoderm determines forelimb / hindlimb identity. Include the experiment, a control, and an interpretation in your answer.arrow_forwardThe Snapdragon is a popular garden flower that comes in a variety of colours, including red, yellow, and orange. The genotypes and associated phenotypes for some of these flowers are as follows: aabb: yellow AABB, AABb, AaBb, and AaBB: red AAbb and Aabb: orange aaBB: yellow aaBb: ? Based on this information, what would the phenotype of a Snapdragon with the genotype aaBb be and why? Question 21 options: orange because A is epistatic to B yellow because A is epistatic to B red because B is epistatic to A orange because B is epistatic to A red because A is epistatic to B yellow because B is epistatic to Aarrow_forward
- A sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. The technician suspected that they had may have made an error in the protocol – what is the most likely explanation? The cell membranes are more resistant than normal. An isotonic solution had been added instead of water. A solution of 0.1 M NaCl had been added instead of water. Not enough water had been added to the red blood cell pellet. The man had sickle-cell anaemia.arrow_forwardA sample of blood was taken from the above individual and prepared for haemoglobin analysis.

The difference in the spectra is due to a pH change in the deoxy-haemoglobin due to uptake of CO2- 2. There is more oxygen-carrying plasma in the oxy-haemoglobin sample. 3. The change in Mr due to oxygen binding causes the oxy haemoglobin to have a higher absorbance peak. 4. Oxy-haemoglobin is contaminated by carbaminohemoglobin, and therefore has a higher absorbance peak 5. Oxy-haemoglobin absorbs more light of blue wavelengths and less of red wavelengths than deoxy-haemoglobinarrow_forward

It has two alpha subunits and two beta subunits. The subunits are joined by disulphide bonds. Each subunit covalently binds a haem group. Conformational change in one subunit can be transmitted to another. There are many variant ("mutant") forms of haemoglobin that are not harmful.arrow_forwardWhich ONE of the following is FALSE regarding haemoglobin? It has two alpha subunits and two beta subunits.

He will have a diet high in iron. He is likely to be suffering from anaemia. He lives at high altitude. He has recently recovered from an accident where he lost a lot of blood.
