STAPHYLOCOCCUS AUREUS (MRSA), COMMUNITY ACQUIRED, MEN WHO HAVE SEX WITH MEN - USA: (MASSACHUSETTS, CALIFORNIA) ************************************************** A ProMED-mail post <http://www.promedmail.org> ProMED-mail is a program of the International Society for Infectious Diseases <http://www.isid.org>
Date: Tue 15 Jan 2008 Source: New York Times [edited] <http://www.nytimes.com/2008/01/15/health/15infe.html?ex=1358053200&en=9307cd688f932b4d&ei=5124&partner=permalink&exprod=permalink>
[Methicillin-resistant _Staphylococcus aureus_ (MRSA) is a type of _S. aureus_ that is resistant to antibiotics called beta-lactams, which include methicillin, oxacillin, and other more common antibiotics such as penicillin, amoxicillin, and cephalexin. MRSA have been causing infections acquired in a healthcare facility, such as a hospital, long-term care facility (e.g., nursing home), or hemodialysis unit for more than 40 years. Most healthcare-associated MRSA (HA-MRSA) are also resistant to multiple other classes of antibiotics than include the macrolides (e.g., erythromycin), fluoroquinolones (e.g., ciprofloxacin), and clindamycin. HA-MRSA are usually sensitive to vancomycin, daptomycin, and linezolid; and are also likely sensitive to the tetracyclines and trimethoprim/sulfamethoxazole. While 25 percent to 30 percent of the healthy population carry _S. aureus_ in their nose and on skin, they infrequently carry HA-MRSA.
The appearance of MRSA in infections acquired outside healthcare settings is a more recent problem. Community-Associated MRSA (CA-MRSA) strains have been generally susceptible to a wider range of antibiotics, other than beta-lactams (e.g., fluoroquinolones and clindamycin). Most CA-MRSA carry a specific type of genetic element that encodes methicillin-resistance (staphylococcal chromosomal cassette Type IV), whereas HA-MRSA carry Types I, II, and III. Many CA-MRSA carry genes that encode Panton-Valentine leukocidin, a toxin that predisposes to severe skin and soft-tissue infections and necrotizing pneumonia.
Unlike HA-MRSA, CA-MRSA often cause infection in children and adults without any obvious risk factors. Clusters of CA-MRSA skin infections have been documented among athletes participating in contact sports, military recruits, Pacific Islanders, Alaskan Natives, Native Americans, men who have sex with men, IV drug users, and prisoners. Factors that have been associated with the spread of CA-MRSA skin infections in otherwise healthy people include close skin-to-skin contact, skin cuts or abrasions, contact with contaminated surfaces (e.g., gym equipment, shared towels), and poor hygiene. 1/19/2008 5:58:11 PM |

The CDC classifies MRSA isolates into pulsed-field types (currently USA100-1200) based on genetic relatedness (McDougal, L. et al. Pulsed-field gel electrophoresis typing of oxacillin-resistant _Staphylococcus aureus_ isolates from the United States: Establishing a national database. J Clin Microbiol. 2003;41:5113-20). USA300, the predominant epidemic clone in numerous outbreaks in the United States, is also increasingly seen in Canada and Europe. International travel and the increasing trend of training or working abroad among health care workers probably is contributing to its global spread (Tietz et al. Transatlantic spread of the USA300 clone of MRSA. NEJM 2005 353:532-533). USA300 has been implicated in skin and soft tissue infections, as well as invasive disease, including septicemia, necrotizing pneumonia, and necrotizing fasciitis.
More recently, some CA-MRSA USA300 have accumulated multiple drug resistance genes resulting in resistance not only to beta-lactam antibiotics, but also resistance to fluoroquinolones, tetracycline, macrolides, clindamycin, and mupirocin (Diep et al. Lancet 2006; 367:731-9). Spread of multidrug-resistant USA300 limits options both for oral therapy and for use of mupirocin topically to eradicate MRSA carrier state during CA-MRSA outbreaks. Because genes that determine resistance to erythromycin, clindamycin, tetracycline, and mupirocin are plasmid-mediated, they could spread quickly. In 2006 and 2007, clusters of infection due to multidrug-resistant CA_MRSA were reported among gay men in San Francisco and Boston (Carleton, Perdreau-Remington. 46th ICAAC. San Francisco, CA. September 27-30, 2006. Abstract C2-1142; Han et al. J Clin Microbiol 2007; 45:1350-2).
The above New York Times news release refers to a recent publication in the Annals of Internal Medicine by the same San Francisco and Boston investigators that further characterizes the epidemiology of multidrug-resistant USA300 infection among men who have sex with men. The MRSA clone USA300 infection of the buttocks, genitals and perineum suggested transmission by skin-to-skin contact during anal intercourse; however the evidence remains circumstantial, since specific sexual practices were not assessed systematically in this retrospective study. The investigators postulated that spread of the MRSA clone USA300 between the Boston and San Francisco outbreaks could have been facilitated by an infected man who had sex with men and who travel frequently between the two cities.
The investigators cited another recent study that reported CA-MRSA clone USA300 infections of the buttocks and genito-perineal area in heterosexual partners (Cook et al. Clin Infect Dis 2007; 44:410-3) and an on-line reader response to the Diep et al. publication questioned if this could be also attributed to heterosexual practice of anal intercourse. - Mod.ML]

So, what do you think the chances of getting MRSA are if you live with people who work in hospitals? 1/23/2008 10:52:37 PM |

My brother's wife is a nurse. He never goes near the hospital but he got it on his arm. It ate into it and had to be surgically opened up to heal. It looked like a gunshot. They said it wasn't the most virulent strain (like I would expect to see in a hospital) and it does get contracted outside the hospital so it may have just been a coincidence. 1/23/2008 11:45:14 PM |

Thanks for confirming what I already thought might be the case... 1/24/2008 2:03:35 PM |

Shit's nasty... if you have a "zit" that doesn't heal as it should get that shit checked. 1/24/2008 5:41:31 PM |
