“…Despite the fact that the risk of enterobiasis increases in the older nursery and school children (over the age of 5 years) (Song et al, 2003;Remm 2006;Li et al, 2015), some researchers have not found a relationship between the age of children and the prevalence of E. vermicularis infection. In our study, similarly to the study results from Argentina (Pezzani et al, 2004), Estonia (Remm & Remm, 2008) and Norway (Bøås et al, 2012), the gender of children was unrelated with the enterobiasis prevalence, although several reports have shown boys to be more frequently affected than girls (Remm, 2006;Fig. 3 Phylogenetic tree constructed using neighbor joining method.…”

SummaryEnterobiasis is a human intestinal parasitic disease caused by human pinworm, Enterobius vermicularis. Despite being the most prevalent nematode infection in Europe and North America, predominantly among in school aged children, the data concerning infection rate and knowledge of genetic variability of pinworms are incomplete. The aim of the study was the estimation of prevalence and molecular typing of Enterobius vermicularis among healthy children in north-eastern Poland. In 2013 -2015, 296 individuals (aged 2 -18 years) from 12 kindergartens, schools and orphanages were examined by the adhesive cellophane tape method. Data on socio-demographic status were collected using a questionnaire. Molecular analysis was performed using the DNA of adult female pinworms and primers targeting the region of cytochrome oxidase I gene. The overall prevalence of enterobiasis was 10.1 %. Enterobius vermicularis infection rates were 3.9 % in children living in families and 32.8 % among the orphans (OR=0.08; 95 % CI: 0.04 -0.19; p<0.001). There were no associations between distribution of enterobiasis and gender, pets possession and the season of examination. In 43.3 % of the infected children enterobiasis was asymptomatic. Based on a molecular marker three different haplotypes of pinworm were identifi ed. All sequences clustered within type B, together with human E. vermicularis isolates from Denmark, Germany, Greece, and Japan. This paper provides complementary data on the occurrence and intraspecifi c variability of E. vermicularis in human population in Europe.

“…However, when analyzing this association for each parasite separately, a different pattern of relation appeared. Our results showed a highly significant association between E. vermicularis infection and perianal itching and insomnia, a result that corroborates that of Pezzani and others 28 and partially with that of Acosta and others 29 who emphasized this relation for perianal itching but not for insomnia. However, although the high frequency of abdominal pain among patients infected with G. lamblia, H. nana, and E. coli infection (88.5%, 85%, and 100% of positive patients, respectively), there was no statistically significant association between the prevalence of infection and the patient's complain (P > 0.05).…”

Intestinal Parasite Infections and Accuracy of Direct Thin and Thick Smear, Formol-Ether Sedimentation, Centrifugal Flotation, and Mini-FLOTAC Techniques among Patients with Gastrointestinal Tract Disorders from the Greater Cairo Region, Egypt

Abstract. The aim of the present study was to assess the frequency of intestinal parasitic infection among patients with gastrointestinal tract disorders from the Greater Cairo region, Egypt. In addition, a comparison was made of the accuracy of direct thin and thick smear, formol-ether sedimentation (FEC), centrifugal flotation (CF), and mini-FLOTAC techniques in the diagnosis of infection. Out of 100 patients, the overall prevalence of parasitic infection was 51%. Only 6% had dual infection. Giardia lamblia was the most common parasite (26%), followed by Hymenolepis nana (20%), Entamoeba coli (8%), and Enterobius vermicularis (3%). Except the statistically significant association between E. vermicularis infection and perianal itching and insomnia (P < 0.001), age, gender, and complaints of the examined individuals had no association with prevalence of parasitic infection. Both FEC and CF were equally the most accurate techniques (accuracy = 98.2%, confidence interval [CI] = 0.95-1.0, and κ index = 0.962), whereas the Kato-Katz method was the least accurate (accuracy = 67.5%, CI = 0.57-0.78, and κ index = 0.333). However, mini-FLOTAC-ZnSO 4 was the most accurate for diagnosis of helminthic infection, and FEC was more accurate for diagnosis of protozoal infection (accuracy = 100%, CI = 1.0-1.0, and κ index = 1).

“…Por outro lado, a ausência de E. vermicularis pode ser justificada pelo método diagnóstico empregado, que não é apropriado para identificar esse helminto. Além disso, esse parasita é predominantemente urbano e está associado a condições satisfatórias de habitação, sendo menos associado às más condições de higiene devido às peculiaridades de sua transmissão 17 .…”

Objective: To evaluate the prevalence of intestinal parasitoses in Native Brazilian children from 2 to 9 years old. Methods:A search for ova and parasites was conducted in the stools of children between 2 to 9 years old living in six indigenous villages located in the Middle and Lower Xingu River, to wit: Pavuru, Moygu, Tuiararé, Diauarum, Capivara, and Ngojwere. The study utilized the Paratest ® kit (Diagnostek, Brazil) to preserve collected stools. Fecal samples were shipped to the Laboratory of the Pediatric Gastroenterology Division of the UNIFESP/EPM, in São Paulo, for analysis. The search for ova and parasites was performed utilizing the Hoffman method, and later through optical microscopic evaluation. Fecal samples were collected one year apart from each other.Results: There were no significant statistical differences between the mean ages of the children from the six indigenous villages studied. The search for ova and parasites found positive results for the stools of 97.5% (198/202) and 96.1% (98/102) of children in the first and second collections, respectively. There was no statistical association with the children's age. The search performed one year later found no differences in the proportion of parasites identified in the first collection for protozoa Conclusion:The high prevalence of intestinal parasitosis matched the elevated rates of environmental contamination in this indigenous community. J Pediatr (Rio J). 2010;86(6):493-496:Epidemiology, prevalence, ancylostoma, giardia, Schistossoma. ResumoObjetivo: Avaliar a prevalência da parasitose intestinal em crianças indígenas de 2 a 9 anos.Métodos: Para a realização do exame protoparasitológico, foram convidadas todas as crianças de 2 a 9 anos, de seis aldeias localizadas no Médio e Baixo Xingu: Pavuru, Moygu, Tuiararé, Diauarum, Capivara e Ngojwere. Para a conservação das amostras de fezes, foi utilizado o kit coletor Paratest ® (Diagnostek, Brasil). As amostras foram transportadas para São Paulo. A pesquisa de helmintos e protozoários foi feita através do método de Hoffman, com posterior pesquisa de ovos e cistos por microscopia óptica. Foram feitas duas coletas com intervalo de 1 ano.Resultados: Não houve diferença significativa entre as idades médias das crianças provenientes das seis aldeias. Resultaram positivas para a presença de parasitas, 97,5% (198/202) Conclusão: A alta prevalência de parasitose intestinal foi compatível com o alto índice de contaminação ambiental dessa comunidade.
