The cause of the increase in CA-MRSA hospital admission.

Introduction

MRSA strains of bacteria are present on the skin of healthy people. Methicillin-resistant Staphylococcus aureus (MRSA) is the causative agent of skin and soft tissue infection in non hospitalized people. As the name suggests these bacteria are resistant to methicillin antibiotics.

Expert Solution

Explanation of Solution

Methicillin-resistant Staphylococcus aureus is a resistant strain of Staphylococcus aureus. Methicillin is related to the penicillin. This methicillin is effective against Staphylococcus aureus but now due to the mutation, the bacteria Staphylococcus aureus became resistant towards the antibiotics. Staphylococcus aureus is a Gram-positive cocci shaped bacteria. They appear in clusters and are nonmotile bacteria. These bacteria contain superantigens, which cause diseases in human. These bacteria are highly virulent, but also present on the skin as normal microflora.

MRSA strains of bacteria have been associated with the hospitals. This is because, in hospitals, there is a higher concentration of patients who suffered from another infected disease or immunocompromised patients that require antibiotics are present. So, the bacteria easily get mutated and developed resistance to antibiotics. Due to this, the hospital-acquired methicillin-resistant S. aureus infection gets an increase.

Conclusion

The immunity of the people present in the hospital is low, which increases the risk of S. aureus infection.

Expert Solution

Explanation of Solution

The studies show that CA-MRSA disease was higher in patients who were suffering from HIV, and diabetes disease. These individuals have tended to form skin lesions or open sores which permit the entry of S. aureus. Thus, the numbers of immunocompromised patients in hospitals are more, which allow bacteria to easily cause disease in these patients.

Conclusion

The patients who are suffering from HIV and diabetes are higher prone to MRSA infection.

Question #3: In the KeyGene paper, the authors state that it would be useful if pollen from an apomict would transmit apomixis-inducing genes to the female in the cross (assuming the pollen is viable). Assuming there was just one gene conferring gametophytic obligate apomixis, and that the two parents are inbreds, what would be the consequences of such a cross if: a) The apomixis was a dominant trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the parental cross. b) The apomixis was a recessive trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the…

Question #5: Assume that two genes are identified that confer gametophytic facultative apomixis in soybean. The genes show independent assortment. Recessive alleles at both loci are required for the facultative apomixis. Facultative apomixis is triggered when the temperature at pollination is above 20 degrees C. At temperatures below 20 degrees C, all reproduction is sexual, independent of genotype. A facultative apomict male, capable of producing viable pollen, was crossed with a sexually reproducing female. Assuming the parents are completely inbred, what are the predicted phenotypic ratios (apomict: non-apomict) for the F1, F2, and DH (F1-derived) generations at each of the following temperatures*: a) 15°C? b) 25°C? *for full credit, show crosses and genotypes where appropriate. Remember to position the female first (left side) in the cross. Type your answer here:
