Colony Count, MicrobialSensitivity and SpecificityProspective StudiesROC CurveFemaleconclusions: Quantitative bacterial cultures of BAL fluid are sensitive and specific in the diagnosis of bacterial pneumonia. The use of antibiotics at the time of BAL reduces the sensitivity of the test, and prolonged ...
Three types of culture media used for bacterial growth did not reveal any significant difference in colony formation. The strains with identical BOX-PCR patterns were used to perform the amplification of 16S rRNA genes (Fig. S9). A phylogenetic analysis was performed using the identified gene ...
Molecular and quantitative culture profiles of the bacterial communities within the oropharynx and nasopharynx is presented in Changes in the microbiota of the upper airways with age JC Stearns et al order to describe the healthy child URT microbiome in the context of the adults with whom they ...
With burn wounds, the type and number of bacteria that grow are correlated to the severity of the infection. When burn tissue specimens have a specific bacterial count above a certain number, then removal of dead tissue (debridement) may be indicated. ...
added to the molten agar. Mix well and pour to a sterile petri dish. • Allow it to set. Incubate at 37oC, colonies will be distributed throughout the depth of the medium. Uses – Gives an estimate of the viable bacterial count in a suspension. – For the quantitative urine cultures...
Most of the potentially pathogenic bacterial colonies were collected in the so-called lung-penetrating fraction of the Andersen sampler. Falsely negative results were frequently indicated by the GSC plate. The GSC plate method cannot be endorsed for the quantitative evaluation of hospital airborne ...
of quantitative culture of intestinal aspirate. Methods: We studied patients with CD in whom culture of intestinal aspirate was evaluated for the presence of anaerobes and aerobes. Bacterial overgrowth was diagnosed if culture demonstrated >
Optical density, Nile red-stained cell count of P. putida cscAB, cell count of S. elongates cscB and colony forming units (CFU) determined from plating are depicted over time in a. Arrows indicate the induction of sucrose export by the addition of 0.1 mM IPTG and inoculation of P. ...
Samples were then serially diluted in whole human blood to obtain samples of progressively decreasing bacterial concentrations. The final concentration of samples was determined by serial dilution, plating, and colony enumeration. The colony count process was performed simultaneously with the RDAP ...
(L1, L2) and bacterial debris. Adjacent to the sieve channels, two side-ports (see blue dashed arrows in Fig.1b) act as vents to purge of air pockets that can develop at the inlet of the device during overnight storage in the incubator. During washing/feeding the fluid first passes ...
