How do c diff spores spread




















If you or a loved one is showing C-diff signs and symptoms, talk to your health care provider. He or she may stop or change your antibiotics, and test your watery stool for C-diff. In many cases this will clear up your signs and symptoms without further treatment. Your doctor can prescribe the proper antibiotic treatment for a C-diff infection.

In about 20 percent of patients, the infection will resolve within 2 to 3 days of discontinuing the antibiotic to which the patient was previously exposed. Antibiotic therapy with metronidazole, vancomycin administered orally , or recently approved fidaxomicin is effective in treating C-diff infection. In some severe cases, a person might have to have surgery to remove the infected part of the intestines. This surgery is needed in only 1 or 2 out of every persons with C-diff.

C-diff infections can be serious and have been linked to the deaths of 20, Americans every year. The majority of cases resolved themselves without serious consequences. A laboratory cell line is exposed to toxin B in fecal eluate. C-diff is confirmed when an antitoxin reverses the effects of the toxin on the cells.

Alternatively, C-diff can be cultured and then tested for the presence of toxins. These methods are too slow to be of use in clinical decisions. FMT therapy involves infusing healthy family donor stools in people with C-diff infections. Unless cleaning is done frequently around symptomatic patients with CDI, including infrequently touched places, reaccumulation of C. Disturbance of already-contaminated articles, such as the bin or bed linen, may contribute to spore aerosolization.

It has been demonstrated previously that bed linen can be contaminated [ 31 ], and during this study we demonstrated that 3 of 30 bed curtains were culture positive for C. Therefore, activities known to liberate particles into the air, such as bed making and curtain drawing [ 32 , 33 ], as well as contact with these items may contribute to the spread and aerosolization of C. The environmental surface sampling results were consistent with previous studies showing that frequently touched areas are most often C.

The patient room door handles were very infrequently found to harbor C. Conversely, C. It might be expected to recover C. There are some limitations to the present study. The air sampler used was reliant on a slit-to-agar impaction method. A similar study [ 19 ] used a machine that recovered airborne material directly into solution but recorded airborne C. It is possible that positioning of the air sampler next to a toilet may have partly explained the higher airborne counts of C.

Because we sampled air close to patients for 5-h periods, we had to use the machine contained within a soundproof box and collect samples via an extension tube. The tube may have resulted in a loss of particulate matter collected onto the plates.

The practicalities of prolonged sampling close to patients may have caused inconsistencies; for instance, during testing the air sampler or tube may have been moved because of visitors or patient care activities. A further difficulty was the timing and extent of symptoms, particularly because our phase 1 data suggested that air contamination by C. Although we had confirmation that patients were C. For future studies, it would be useful to conduct air sampling before this would also increase sampling of control subjects, which was limited in our study and during the course of CDI to determine the frequency of C.

It remains unclear whether the frequent presence of particular strains in health care environments reflects the burden of CDI caused by epidemic types or whether these have enhanced capacity to persist—for example, because of greater sporulation [ 30 , 35 , 36 ]. Nevertheless, our results suggest that there is a clear risk for C.

The efficacy of these approaches as a control mechanism for CDI remains unproven. By contrast, the results of the present study do justify the use of single rooms for patients with suspected or proven CDI, even when such resources are limited [ 8 ]. In particular, we believe our findings underscore the importance of early patient isolation, as soon as possible after the onset of diarrhea and before laboratory diagnosis of CDI is confirmed.

Allowing even a few hours before patient isolation or the wait until laboratory diagnosis is obtained, even with rapid tests, may not be adequate to prevent environmental dissemination of C. Such a mechanism would at least partly explain the rapid spread and large outbreaks of CDI typified by epidemic strains, such as C. Recognition of the risk of airborne dissemination provides an opportunity to reduce transmission, especially of epidemic C. Financial support. Google Scholar.
