| Abstract |
The diagnostic techniques based on polymerase chain reaction (PCR) for the detection of Schistosoma spp. DNA in stool, serum, plasma and urine has shown high sensitivity and specificity solving the problems for the low worm burdens and low transmission rates facing the routine microscopic diagnosis. Since PCR assays require efficient unbiased procedures of extraction and purification of nucleic acids. This study compared the efficiencies of simple, manual and feasible DNA extraction methods; a salting out and resin method, phenol/chloroform method to a commercial extraction kit through PCR analysis of human urine and serum samples spiked with known amounts of adult Schistosoma mansoni DNA confirmed by the application on real samples from patients. In artificially spiked urine gradient, the best mean diagnostic performance was that of salting out and resin then phenol/chloroform and last for the commercial kit. All three methods gave positive results in all tested urine samples which insures comparable high efficiency for DNA detection. In artificially spiked serum gradient, the highest mean diagnostic performance was obtained by the kit then salting out and resin and last by phenol chloroform. In patients' urine samples the phenol/chloroform method showed the highest mean diagnostic performance followed by the resin and then the kit. Using patients' serum samples the resin method showed equal mean diagnostic performance with the phenol/chloroform method which was higher compared to the kit. As regards sensitivity from urine samples the resin and phenol/chloroform showed equal results using artificial gradients and patients' samples. In serum samples the resin and phenol/chloroform showed equal results using artificial gradients while the resin showed better results in patients' samples. It is recommended to extract DNA from urine samples and to use the salting out and resin as a manual DNA extraction method from patients' samples for the molecular diagnosis of Schistosoma mansoni infection. |

This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 08 September 2015.
All research outputs
#17,772,019
of 22,826,360 outputs
Outputs from Journal of Parasitic Diseases
#159
of 429 outputs
Outputs of similar age
#219,818
of 302,406 outputs
Outputs of similar age from Journal of Parasitic Diseases
#8
of 43 outputs
Altmetric has tracked 22,826,360 research outputs across all sources so far. This one is in the 19th percentile – i.e., 19% of other outputs scored the same or lower than it.
So far Altmetric has tracked 429 research outputs from this source. They receive a mean Attention Score of 1.4. This one has gotten more attention than average, scoring higher than 55% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 302,406 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 24th percentile – i.e., 24% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 43 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 67% of its contemporaries.
