Amother brings her three-year-old daughter to her pediatric office stating that the girl has had fever and chills for three days. the girl also has a large, intensely red patch with a distinct margin on her leg and a nearby swollen lymph node. when the health care provider touches the area, it is firm and warm, and the girl screams in pain. based on these observations, the provider makes a presumptive diagnosis and begins treatment. part a based on the observations given, what is the probable diagnosis made by the health care provider?

Erysipelas

Erysipelas is an acute infection caused by group A Streptococcus bacteria. Causes skin rash usually on the legs and toes, face, arms, and fingers with a distinct margin (just like the toodler had on her leg).
It can spread to lymph nodes and some other symptoms are fever, chills, and pain on the affected areas.
It can be treated with penicillin V.

Seeing all the symptoms, the doctor diagnosed the diseases to be Erysipelas. It is a superficial form of cellulitis, by Group A beta haemolytic Streptococcus pyogenes.

Proteins are the workhorses of the cell, controlling virtually every reaction within as well as providing structure and serving as signals to other cells. proteins are long chains of  amino acids  , and the exact sequence of the amino acids determines the final structure and function of the protein. instructions for that sequence are encoded in  genes  . to make a particular protein, a messenger ribonucleic acid (mrna) copy is made from the gene (in the process called  transcription  ), and the mrna is transported to the  ribosome  . protein synthesis, also called  translation  , begins when the two ribosomal subunits link onto the mrna. this step, called initiation, is followed by elongation, in which successive amino acids are added to the growing chain, brought in by transfer rnas (trnas). in this step, the ribosome reads the  nucleotides  of mrna three by three, in units called  codons  , and matches each to three nucleotides on the trna, called the anticodon. finally, during termination, the ribosome unbinds from the mrna, and the  amino acid  chain goes on to be processed and folded to make the final, functional protein
