Vancomycin

a) The most common opportunistic infection(s) that result from taking the antibiotic

b) 1 example of resistance to this antibiotic in a clinical case

Expert Solution

Answer a):

The most opportunistic infections that may result from taking the antibiotic Vancomycin are nosocomial infection with vancomycin-resistant intestinal flora.

Vancomycin treatment is required to remove MRSA - Methicillin-Resistant Staphylococcus aureus infections, either skin or septicemia. Both need a longer duration of treatment with the drug which exposes the normal flora to this antibiotic for a long duration as well and results in some of these commensals acquiring resistance to this drug.

Answer b):

Vancomycin-Resistant Enterococci (VRE)

Enterococci lactic acid bacteria and are gram-positive cocci that grow as diplococci or short chains. There are about 17 known species of Enterococci the most common being Enterococcus fecalis. In human and animal gut it is part of the normal flora, but has now emerged as one of the serious opportunistic pathogens. Excessive and indiscriminate use of antibiotics has resulted in an increase in multidrug-resistant opportunistic pathogens.

Tetanus, commonly called lockjaw, is the result of a bacterial infection from the bacterium Clostridium tetani. It produces muscle spasms (think lots of co-contraction of muscles that would not normally occur). Once the bacteria has made its way into the body, it is taken up by neurons, ultimately making its way to inhibitory interneurons in the spinal cord that will synapse onto α motor neurons that innervate muscle fibers. Use your knowledge of the stretch reflex to answer the following...

Henry Baer, below, with his mother, Violet Cunningham. Baer, 39, died from an antibiotic-resistant staph infection after his bloodline had become disconnected during a dialysis treatment. (Photo courtesy of Karen Gable) Henry Baer went in for his third dialysis treatment on New Year's Eve day in 2005. It turned out to be his last. He was only 39, but years of diabetes and high blood pressure had caused Baer's kidneys to shut down. Built-up waste and fluid were causing his...

Human papilloma virus (HPV) is the most common sexually transmitted infection, with 45% of 20-24 yr old women infected. Infection of the genitalia and cervix with HPV increases the risk of cervical cancer 10-fold. Two proteins encoded by HPV DNA bind to p53 and Rb. Which of the following do you think would Best describe the function of those two HPV proteins? proto-oncogenes oncogenes tumor suppressor gain of function mutant proteins
