Doctor insights on:
Anaerobes: This type of bacterial culture is designed to allow anaerobic bacteria to grow, that is, ones that grow in the absence of oxygen. Much of the bacterial microbiome in the mouth and intestines are in this category. Many bacteria are facultative, they can grow with or without oxygen, sort of ac-dc. ...Read more
Urine Culture Results
50,000-100,000 CFU/mL Staphylococcus coagulase negative not S.saprophyticus
10,000-50,000 CFU/mL Multiple organisms
See below: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, the colony count, the dominant organism and multiple organism all suggest that this is not real urinary infection. The organisms are likely to be skin contaminants. ...Read more
Aerobic semen culture showed enterococcus. Anaerobic culture was clear of bacteria. Does it mean an enterococcus species easier to be treated?
No: Aerobic means it grows in oxygen. Anaerobic means the bacteria grow in the absence of oxygen. Whether bacteria are aerobic or anaerobic does not determine how hard those bacteria are to treat. That is determined by whether we have readily available antibiotics capable of killing them. ...Read more
It may but...: It depends on the resistance profile of specific strain of klebsiella. Many strains acquired in the 'community' are very sensitive to almost all antimicrobials except penicillin and Ampicillin and certainly sensitive to piperacillin/tazobactam. However, especially when acquired in a hospital, klebsiella can be quite resistant to therapy including pip/tazobactam. ...Read more
Similar: In many cases the procedures for collecting a specimen can be the same for both. Ideally you want to avoid contamination with bacterial cultures. With fungal cultures the growth media used can often help avoid bacterial contamination. Either way the process is pretty simple even if a blood culture may be involved. ...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
Cultures : Await final cultures and sensitivities before determining antibiotics. ...Read more
Culture/Gram's stain: Depends upon whether these were from the culture or the stain of some clinical material, where the culture was obtained from, and why. This may be an entirely inconsequential result or possibly represent severe illness, but would need far more info to say. Discuss this with the doctor who cultured you. If this was from your tonsil it is probably Strep and you should have been treated. Get better. ...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
Can staphylococcus haemolyticus cause prostatitis?
All major std negative. Urine culture shows staphylococcus haemolyticus. Prostatitis?
High vaginal swab result: scanty leucocytes & gram positive cocci, numerous gram positive bacilli, moderate epithelial cells . Result shows infection?
Not likely: Bacteria are part of the contents of the vaginal barrel. When infection is present due to bacteria there are usually large numbers of leucocytes and few epithelial cells. All told, however, test results are not always accurate, and best to discuss this with the doctor who ordered this to begin with. ...Read more
Urine; moderate WBC, no nitrites, culture <50k multiple non-uropathogenic gram positive bacteria. No symptoms. Possible contamination? Antibiotics??
Contaminant: Infection is when pathogens (bacteria for example) invade your tissues. This almost always produces signs which include redness, swelling, warmth and pain. In the absence of symptoms this is a contaminant or a colonization of your urinary tract. Note: Do not test urine without a good reason.... ...Read more
Incomplete killing: Mutations in bacteria that lead to resistance can occur when bacteria are exposed to antibiotics in doses that are not strong enough to kill them. The bacteria then can mutate and develop resistance. A favorite professor of mine would always say "dead bacteria can't develop resistance.". ...Read moreSee 1 more doctor answer
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
