“…The sensitivity of the assay was determined by cloning the gdh assemblage E PCR amplicon into a plasmid vector, and then spiking known amounts of plasmid into faecal samples, extracting the DNA and screening by qPCR. The assay could reliably detect 1 Giardia cyst per µl of faecal DNA extract, which is similar to or better than sensitivities reported previously for Giardia qPCR detection assays (Helmy et al, 2009;Almeida et al, 2010;Baque et al, 2011;Stroup et al, 2012).…”

“…Desta forma, as técnicas de reação de amplificação e quantificação de genes comuns às espécies de Cryptosporidium, presentes tanto em amostras clínicas como em amostras ambientais, são consideradas promissoras proporcionando informações precisas de interesse para saúde pública já que podem ser aplicadas tanto em estudos de avaliação de surtos como investigação de casos isolados (VERWEIJ et al, 2003;PLUTZER et al, 2008;YU et al, 2008;RYU et al, 2010;BAQUE et al, 2011;SOUZA et al, 2012). GenBank utilizando a ferramenta BLAST.…”

“…Cryptosporidium apresenta oito cromossomos com extensão de aproximadamente 9.2 milhões de pares de bases e o DNA ribossomal amplificado por meio do gene 18S rRNA apresenta cinco cópias por genoma haploide (esporozoíto) consistindo em 20 cópias por oocisto, favorecendo a sua detecção por este gene (Le BLANCQ et al 1997;BANKIER et al, 2003;XU et al, 2004 (VERWEIJ et al, 2003;PLUTZER et al, 2008;YU et al, 2008;RYU et al, 2010;BAQUE et al, 2011;SOUZA et al, 2012).
