In this study, we determined Candida burden in the first positive blood culture and explored factors that affect organism numbers and patient outcomes.
Sources of the species found in humans, P. jirovecii, are limited and often low in organism numbers.
Median and interquartile ranges of organism numbers [total numbers and numbers of co-infecting organisms] and specimen numbers in each group are shown in table 2 along with details of the types of co-infecting organisms.
The organism numbers in lung tissue, quantified by microscopic enumeration, increased from log 4.69 after 4 weeks of immunosuppression to log 9.35 after 10 weeks of immunosuppression.
These applications differ from most typing efforts in that the usual purpose of typing is to evaluate genetic polymorphism, whereas these assays examine organism numbers and viability.
An important limitation in its clinical management has been the inability to evaluate therapeutic response or to temporally measure the organism numbers because of the absence of an in vitro culture system.

Cultivation of Pneumocystis organisms in vitro requires a large seed population and supports rather modest increases in organism number for a very limited period of time (17).
For each positive culture result, the type of isolated organism, number of positive culture sites, time to culture positivity, the presence of focal or generalised clinical signs of infection and an overall assessment of illness were recorded.
