RESUMO

To study the microbiological contamination of kitchen dishcloths in Chinese housholds, 1010 'in-use' kitchen dishcloths were collected from residential premises in Beijing and Shanghai, and they were sent to the laboratory for microbiological quality analysis. The aerobic plate counts for dishcloths were 10-109 cfu/cm2 in the range of 150 cfu/cm2 to 1.776×109 cfu/cm2 (Beijing) and 62.5 cfu/cm2 to 8.75×108 cfu/cm2 (Shanghai). Nineteen species of bacteria were detected in the dishcloths, most of which were conditional pathogenic bacteria. This study found a significant difference in the aerobic plate counts of dishcloths with regard to type, number of the days used, activities used for, and some family factors. The findings of the study highlight the potential for contamination of kitchen dishcloths within homes.

RESUMO

<p><b>OBJECTIVE</b>To assess and compare the Human Papillomavirus (HPV) detection efficiency and the potential clinical utility of PCR sequencing-based technology.</p><p><b>METHODS</b>Four HPV consensus primer sets (GP5+/6+, MGP, MY09/11, and PGMY09/11) were used in order to amplify a broad spectrum of HPV types for HPV infection in 325 cervical samples and the PCR products were sequenced afterwards for the HPV genotyping.</p><p><b>RESULTS</b>The HPV-positive rate was 75.4%, of which 35.5% harbored more than one HPV genotype. A total of 36 different genotypes was found, with HPV 16 (24.1%) being the most prevalent, followed by HPV 58 (13.3%) and HPV 52 (9.6%). There were substantial to almost perfect agreements between different primer sets regarding HPV detection efficiency, with the kappa value varying from 0.751 to 0.925, MGP, and PGMY09/11 were the most effective in detecting multiple infections (P < 0.001). With each of the primer sets, a board range of HPV types could be identified, though there were several differences for a few genotypes.</p><p><b>CONCLUSION</b>The substantial agreement between PCR-sequencing and HC2 for the detection of high-risk HPV (kappa=0.761) indicated that PCR-sequencing is also suitable for routine HPV screening.</p>
