grama need help docs - okt3 - ArchivalUser - 11-29-2007 A 70-year-old female patient was readmitted to a local hospital with fever and chills following cardiac surgery at a major teaching institution. Blood cultures were taken and a Gram-positive coccus grew from the blood cultures within 24 hours. Initial tests indicated that this isolate was resistant to penicillin. Which of the following is the treatment of choice for the isolate? A. Gentamicin B. Gentamicin and ampicillin C. Ciprofloxacin D. Rifampin E. No available treatment 0 - ArchivalUser - 11-29-2007 dd 0 - ArchivalUser - 11-29-2007 ee 0 - ArchivalUser - 11-29-2007 please explain ur choice thanks 0 - ArchivalUser - 11-29-2007 for mrsa vancomycin ,if not available then rifampin can be given. 0 - ArchivalUser - 11-29-2007 subacute bact endocarditis in elderly man-enterococcus 0 - ArchivalUser - 11-29-2007 yes dr_smile The answer is: E Enterococci causes a wide variety of infections ranging from less serious, for example, urinary tract infections, to very serious, such as septicemia. A Gram-positive coccus resistant to penicillin must be assumed to be enterococcus until other more definitive biochemical testing places the isolate in one of the more esoteric groups of Gram-positive cocci. Once isolated, there are a variety of tests to speciate enterococci. However, penicillin-resistant, non--lactamase-producing, vancomycin-resistant, Gram-positive cocci are most likely Enterococcus faecium. There are a variety of mechanisms for vancomycin resistance in E. faecium and they have been termed Van A, B, or C. These isolates have become one of the most feared nosocomial pathogens in the hospital environment. Unfortunately, no approved antibiotics can successfully treat vancomycin-resistant enterococci (VRE), only some experimental antibiotics such as Synercid. 0 - ArchivalUser - 11-29-2007 thanks for explanation.i was wrong 0 - ArchivalUser - 11-29-2007 me too 0 - ArchivalUser - 11-29-2007 but is it subacute endocarditis? |
