• Infection
  • Since approximately 80% of infectious diseases are known to be transmitted by touch, and pathogens found in healthcare facilities can survive on inanimate surfaces for days and even months, the microbial burden of frequently touched surfaces is believed to play a significant role in infection causality. (wikipedia.org)
  • Clinical trials are being conducted on microbial strains unique to individual healthcare facilities around the world to evaluate to what extent copper alloys can reduce the incidence of infection in hospital environments. (wikipedia.org)
  • IL-1, TNF, histamine and prostaglandin D2) and suppressed levels of IL-10 at the site of microbial infection are likely to amplify local inflammatory responses. (wikipedia.org)
  • coli
  • The results from real-time PCR and plate count analysis indicated that 95% of the E. coli retained inside the filters were either non-viable or could not be recovered by colony counting techniques. (biomedsearch.com)
  • Images obtained from an epifluorescent microscope showed that E. coli cells were embedded inside the biofilm matrix and presented mainly as microcolonies intertwined with other microorganisms, which was consistent with findings from standard plate count methods and qPCR. (biomedsearch.com)
  • The plate count is linear for E. coli over the range of 30 - 300 CFU on a standard sized Petri dish. (wikipedia.org)

  • Campylobacter
  • Two more trials were carried out to evaluate a wider range of caprylic acid doses on cecal Campylobacter counts, in which day-of-hatch chicks (n=90 per trial) were assigned to 9 treatments: negative controls (no Campylobacter, no caprylic acid) and caprylic acid doses of 0 (positive controls), 0.35, 0.525, 0.7, 0.875, 1.05, 1.225, and 1.4% (n=10 chicks/treatment). (biomedsearch.com)
  • In all 4 trials, the 0.7% dose of caprylic acid consistently reduced Campylobacter content counts compared with the positive control. (biomedsearch.com)
  • Biofilms
  • The pulsed-power imparts electromagnetic fields into the cooling water and the induced fields have a direct effect in preventing mineral scale formation on equipment surfaces and controlling microbial populations to very low levels while also significantly reducing biofilms present in cooling systems. (wikipedia.org)
  • units
  • The number of colony-forming units of Enterobacteriaceae in gastric aspirates was also significantly lower in the sucralfate group (p = 0.0037). (biomedsearch.com)
  • Biofilm population density is recorded as log colony forming units per surface area. (astm.org)
  • Expressing results as colony-forming units reflects this uncertainty. (wikipedia.org)
  • context
  • The term is most often used in the context of bioburden testing, also known as microbial limit testing, which is performed on pharmaceutical products and medical products for quality control purposes. (wikipedia.org)
  • Thus
  • Thus after a colony is reduced by 1 D, only 10% of the original organisms remain, i.e., the population number has been reduced by one decimal place in the counting scheme. (wikipedia.org)
  • levels
  • Products or components used in the pharmaceutical or medical field require control of microbial levels during processing and handling. (wikipedia.org)
  • Results showed N. sphaerica with the highest spore counts at ground levels and low altitudes around 40m. (wikipedia.org)
  • Method
  • citation needed] An advantage to this method is that different microbial species may give rise to colonies that are clearly different from each other, both microscopically and macroscopically. (wikipedia.org)
  • Generally
  • The experimenters would generally take a picture of each plate they need to count and then analyse all the pictures (this can be done with a simple digital camera or even a webcam). (wikipedia.org)
  • small
  • The drop dish must be read while the colonies are very small to prevent the loss of CFU as they grow together. (wikipedia.org)
  • measure
  • The aim of bioburden testing is to measure the total number of viable micro-organisms (total microbial count) on a medical device prior to its final sterilization before implantation or use. (wikipedia.org)
  • likely
  • However, solitary cells are the exception in nature, and most likely the progenitor of the colony was a mass of cells deposited together. (wikipedia.org)
  • unique
  • Featuri ng unique imaging and easy to use software, our colony counters are ideal when your food testing lab needs accurate, objective and secure results. (selectscience.net)
  • However
  • however, it has analogous uses in other microbial resistance and death rate applications, such as (but not limited to) those of ethylene oxide and radiation processing. (wikipedia.org)
  • mass
  • The initial white translucent looking colony of N. sphaerica turns brown/black due to mass sporulation of conidia from the conidiophores. (wikipedia.org)
