“…First, both of the Chinese children and obese Mexican children may have intestinal parasitic infections, since Trichuris trichiura was detected in their guts. Trichuris trichiura can cause trichuriasis [ 30 ], which is prevalent in warm, moist, tropical and subtropical regions of the world [ 31 ]. Sichuan province is in the subtropical zone with a humid climate and the Greater Mexico City is in the tropical zone, which might account for the occurrence of Trichuris trichiura .…”

Background The prevalence of obese children in China is increasing, which poses a great challenge to public health. Gut microbes play an important role in human gut health, and changes in gut status are closely related to obesity. However, how gut microbes contribute to obesity in children remains unclear. In our study, we performed shotgun metagenomic sequencing of feces from 23 obese children, 8 overweight children and 22 control children in Chengdu, Sichuan, China. Results We observed a distinct difference in the gut microbiome of obese children and that of controls. Compared with the controls, bacterial pathogen Campylobacter rectus was significantly more abundant in obese children. In addition, functional annotation of microbial genes revealed that there might be gut inflammation in obese children. The guts of overweight children might belong to the transition state between obese and control children due to a gradient in relative abundance of differentially abundant species. Finally, we compared the gut metagenomes of obese Chinese children and obese Mexican children and found that Trichuris trichiura was significantly more abundant in the guts of obese Mexican children. Conclusions Our results contribute to understanding the changes in the species and function of intestinal microbes in obese Chinese children.

“…(24) A infecção é adquirida pela ingestão de água ou alimentos contaminados e é geralmente assintomática. No entanto, quando ela progride de uma infecção leve a grave, sinais clínicos específicos se põem de manifesto, (25) como a insurgência da chamada Síndrome Disentérica por Trichuris (SDT), especialmente em crianças, sendo caracterizada por diarreia mucóide, sangramento e prolapso retal complicado com infecção secundária bacteriana grave. (26) A prevalência geral da Tabela 4, quanto à presença de A. lumbricoides, variou de 0,83% (27) a 20,86%, (4) com uma prevalência média de 8,03%.…”

Alguns pesquisadores e laboratórios clínicos utilizam apenas uma técnica para detecção de parasitos intestinais, podendo isto subestimar os achados. Enteroparasitos afetam principalmente populações com vulnerabilidade social, como os catadores. Alguns destes trabalhadores se reúnem em cooperativas, melhorando a condição de trabalho e o rendimento mensal, porém ainda não é o adequado, sendo por vezes insalubre. Nosso objetivo foi verificar a prevalência de enteroparasitos e comparar duas técnicas parasitológicas em suas medidas de efeito em catadores de material reciclável que trabalhavam em cooperativas no Sul do Brasil. Três amostras de fezes de 48 catadores, de seis cooperativas, foram coletadas em dias alternados, para a análise de parasitos. Duas técnicas de concentração de amostra foram utilizadas (Faust e Ritchie) e testadas para verificação da melhor a ser utilizada. A prevalência de parasitos em catadores foi de 62,5% (30/48) utilizando as duas técnicas em paralelo, sendo que quando utilizadas sozinhas, essa prevalência foi menor. Diagnosticaram-se helmintos e protozoários, tanto patogênicos quanto comensais. A partir da análise estatística, provou-se que as técnicas parasitológicas fornecem melhores resultados quando utilizadas em paralelo, ou seja, quando utilizamos as duas técnicas juntas e em três amostras de fezes. ARTIGOS / ARTICLES CIÊNCIAS BIOLÓGICAS E DA SAÚDEPalavras chave: Parasitos. Saúde pública. Reciclagem.Some researchers and clinical laboratories use just one technique for the detection of enteroparasites, allowing substandard findings. Enteroparasites mostly affect the socially vulnerable population, like the waste pickers. Some of these workers are gathered in cooperatives where work conditions and monthly wage are better. However, this environment is still not adequate being, sometimes, unsanitary. The objective was to study the enteroparasite prevalence and compare the two parasitological techniques in their effect measure in recyclable waste picker who were working in cooperatives in the south of Brazil. Three stool samples from 48 pickers from six cooperatives were collected in alternate days for parasite analysis. Two sample concentration techniques were used (Faust and Ritchie) and tested to verify which was the best to use. The parasite prevalence in waste picker was 62.5% (30/48), using the two techniques concurrently. When used individually, the prevalence was lower. Commensal and pathogenic helminths and protozoan were diagnosed. From the statistical analysis, it was proved that the Resumo
