Microbiology Of Mrsa
What are the differences between MRSA (methicillin-resistant staphylococcus aureus) or c-diff (clostridium difficile)?
Totally different: They are totally different bacteria. Mrsa causes disease by invading the body, multiplying and causing tissue injury. Clostridium difficile causes disease by overgrowth in the intestinal lumen and producing toxins that injure the colonic mucosa causing diarrhea and colitis. ...Read moreSee 1 more doctor answer
See below: Staphylococcus are a genus of bacteria usually divided into coagulase negative and positive. The coag positive staph are staph aureus which cause many infections. Mrsa are resistant to the semisynthetic penicillins like methicillin. Mssa are sensitive to these antibiotics. Coag neg staph include many species like staphylococcus epidermidis which colonize normal skin and infrequently cause disease. ...Read more
A bad type.: Mrsa is a potent strain of staph bacteria that worries doctors because it is resistant to the antibiotic methicillin, which for many years was the single best treatment for staph infections. It is usually treatable with other antibiotics, such as Bactrim (sulfamethoxazole and trimethoprim) or doxycycline, but such infections can be very virulent and contagious. ...Read moreSee 1 more doctor answer
Sinus Infectipn-gene sequencing of a culture was positive for staphylococcus epidermidis MRSE. Are antibiotics the only way to cure the infection?
Appropriate Rx?: That seems like an unusual bacteria for sinusitis – I question the accuracy of the test. Probably that was a skin contaminant that has nothing to do with your sinusitis. Actually, the IDSA discourages antibiotic use for acute sinusitis. Would seek ID specialist or ENT. Antiinflammatory meds may help. Antibiotics could have side effects. Need to try conservative treatment first. Hope that helps. ...Read more
Differentiate between staphylococcus and streptococcus species in terms of Morphology,Biochemical test and Culture?
Staph vs Strep: This is a complex subject that is not conducive to extensive discussion here. Suggest you get a microbiology text. Staphylococci are larger and grow more in clumps than chains. Staph that produce coagulase are species aureus, the others are a wide variety of less pathogenic organisms except for lugdenensis which has characteristics of aureus in producing disease. ...Read more
A total of 8 different organisms in my wound: e. Coli, acinetobacter baumannii, stenotrophomonas, are these hospital acquired infections?
Yes.: They can all be hospital acquired infections. ...Read more
Common skin germ: Staph aureus is just a common skin germ that is often found in abscesses or pustules. It is considered more invasive or aggressive than many other skin germs.MRSA is one strain of this germ. ...Read more
history of sinus infections +dx of UCTD. Recent sinus cultures positive atypical bacteria (Serratia marcescens +Stenotrophomonasmaltophilia - Why?
ID physician: S maltophilia is an organism of low virulence and frequently colonizes fluids used in the hospital setting and patient cultures. Serratia species are opportunistic gram-negative bacteria that are widespread in the environment. And something is definitely wrong here...unless your on say prednisone (for MCTD) and didn't mention this. You should see an infectious disease physician ASAP. ...Read more
Mostly different.: Cellulitis is a skin infection causing redness, swelling, and/or pain. It can be caused by MRSA rather than typical staph (MSSA) or strep in certain settings. C diff is not directly related to the other two unless of course antibiotics are taken for cellulitis/MRSA which can lead to alteration of gut flora and C diff. ...Read moreSee 1 more doctor answer
UTI or septicemia: If you have urinary symptoms ie. Burning, urgency, frequency, flank pain, fever you and if you have wbc's in your urine you haave a urinary tract infection with s. Aureus. As persons with s. Aureus in their blood will frequently have the organism spread to their kidneys and appear in the urine you shoul have blood cultures done before antibiotic treatment and be checked for signs of systemic inf. ...Read more
Research shows different pre-biotics target different locations on the colon.Is a single broad spectrum pre-biotic available to target the whole colon?
Is GBS a second cause of my UTI? culture results: 10,000 CFU/mL Streptococcus Group B, (S. agalactiae) AND >100,000 CFU/mL Escherichia coli
Yes: All staph infections, including mrsa, are spread through skin contact. Because of their close proximity to each other, kids in school are a high risk group over-all, and the younger ones are more at risk as they tend to touch each other more and wash their hands less. ...Read moreSee 1 more doctor answer
Urinalysis culture? 10,000-50,000 CFU/mL of Mixed nonuropathogenic Gram positive flora. May represent colonizers from external and internal genitalia?
Staph aureus: We are all colonized with staph aureus. Whether or not we become infected with these organisms depends on multiple different factors. The ones that are in your cat are the same as the ones in your gut, or in your nasopharynx or on your skin. They have the same disease producing mechanisms. Whether they will infect you is problematic. ...Read more
Diffusion: Thank you for being candid about your writing a science paper. This is a very basic question about microbiology, and you'd be doing yourself a favor to go to a good textbook of microbiology and learn the essentials rather than try to get answers piecemeal from physicians. ...Read more
