  • The standardized real-time PCR assay for toxin genes of C. difficile was used to screen for toxigenic C. difficile in fecal samples from 71 preweaned calves, 53 retail ground meat samples, and 27 pasteurized milk samples. (psu.edu)
  • Mild cases generally improve with discontinuation of the drug, while severe cases may require supportive therapy and treatment with an antimicrobial agent effective against C difficile. (drugs.com)
  • This strain produces substantially more toxin, causes more severe illness with greater chance of relapse, is easier to transmit, and does not respond as well to antibiotic treatment. (msdmanuals.com)
  • Professor Richard James, Director of CHAI, said: "This important research will examine the genetic differences between these different strains of superbug which will give us a greater insight into the mechanisms they use to multiply and attack the human body. (nottingham.ac.uk)
  • In fact, further study of 21 different strains showed that the RT027 and RT078 strains, and only those strains, grow unusually well on a diet of trehalose. (nih.gov)
  • A PCR assay targeting the capsid gene of the myoviruses was designed to examine molecular diversity of C. difficile myoviruses. (le.ac.uk)
  • A case of CDI is defined as a positive C. difficile toxin assay or a positive C. difficile molecular assay (e.g. (cdc.gov)
  • The capsid gene can be used as a tool to identify C. difficile myoviruses present within bacterial genomes. (le.ac.uk)
  • Know the difference between strain vs. species vs. genus. (chinesemedicinedoc.com)
  • Clostridium difficile is another bacterial species that has gained antibiotic resistance. (biokplus.com)
  • The human health implications of this finding are unclear, but with the virulence of toxinotype III strains further studies are required. (cdc.gov)
  • Although norovirus strains are evolving, they do not change as fast as influenza strains, he pointed out. (medscape.com)
  • However, patient diagnosis was made solely through fecal toxin testing, and strains were not characterized. (cdc.gov)
  • A total of 24 fecal samples (33.80%) were positive for toxigenic C. difficile using either multiplex real-time PCR or culture. (psu.edu)
  • Toxin-encoding C. difficile was detected in 23 enriched fecal samples using the multiplex real-time PCR assay and only 15 samples using culture techniques. (psu.edu)
  • Eleven fecal samples were positive for all 4 toxin genes, suggesting that preweaned calves may be a likely source for toxigenic C. difficile. (psu.edu)
