Human parechovirus (HPeV), a member of Picornaviridae family, is a widespread pathogen causing a wide spectrum of diseases. Like other picornaviruses, HPeV genome recombination has been detected. A total of 322 fecal samples were collected from children outpatients in Guangzhou, China, including 42 (13.0%, 42/322) HPeV-positive samples detected in most of the infected children less than two years old. Seven HPeV genotypes (HPeV1, HPeV3, HPeV4, HPeV5, HPeV6, HPeV8 and HPeV14) were detected, among which, HPeV14, a rare genotype, was reported for the first time in children with acute gastroenteritis in China. This study revealed recombination events in eight samples. Clinical profiles did not yield statistical significance between children with HPeV infection alone and cases without pathogens detected. In conclusion, this study demonstrated that HPeV circulated in Guangzhou, China is diverse genetically, which provided evidence of recombination in HPeV in China. J. Med.

The association between CD14 gene C-159T polymorphism and tuberculosis (TB) susceptibility remains inconclusive. To derive a more precise estimation of the correlation, we performed a meta-analysis summarize the possible at a systematic manner. PubMed, HighWire and ScienceDirect databases covering all papers (up to November 2012) were searched. Statistical analyses were conducted by Rev-Man and STATA. Random- and fixed-effect models were used to estimate pooled odds ratios (ORs) and 95 % confidence intervals (CIs), based on between-study heterogeneity. Eight published case–control studies investigating the relationship between C-159T polymorphism in CD14 gene and TB susceptibility were included. Results showed that individuals with T allele have an increased risk of TB compared with those with C allele (OR (95 % CI) was 1.52 (1.11, 2.08) for TT vs. TC + CC, P < 0.001; 1.27 (1.01, 1.61) for T vs. C, P = 0.04). When stratified by ethnicity, variant TT homozygote carriers had an 86 % increased risk of TB in Asians (OR (95 % CI) was 1.86 (1.57, 2.20) for TT vs. TC + CC, P < 0.001), but not in Caucasians (OR (95 % CI) was TT vs. TC + CC: OR = 0.78, 95 % CI = 0.51–1.21, P = 0.61). This meta-analysis suggests that C-159T polymorphism in CD14 gene is associated with increased risk of TB, especially in Asians, but not in Caucasians. © 2014, Springer Science+Business Media Dordrecht.
