Results
The sample was composed by 7 patients,
selected by convenience,
that accepted to participate.
The mean number of colony-forming units (CFU) that were effectivelly present in the patient was 38.19.
This value was used as reference for CFU that may pass to the receiver and the CFU that passed to the receiver.
The normalized results can be seen in Fig. 2.
When compared the types of swab collection,
the only significative difference was seen between the effective CFU present in the patient and the CFU that passed to the receiver (Brown-Forsythe test was 7.705 with a P=0.0038).
The types of bacteria that were possible to evaluate because of the types of selective culture medias for incubation available were:
- SB media for evaluating the presence of streptococcus presented a mean of 15.7 CFU;
- Chapman media presented a staphylococcus epidermis mean number of 4.3 CFU and a staphylococcus aureus mean number of 9.9 CFU;
- The MacConkey media presented a enterococcus mean number of 2.29 CFU and a proteus mean number of 1.29 CFU.
In Fig. 3 it is possible to see a graph with the quantitative representation of CFU per type of bacteria.
It is possible to see that streptococcus was the most common bacteria type.
