AbstractIn order to determine the prevalence of intestinal parasites among labourers from Thailand in Taiwan, the stool samples from 1364 Thai labourers were examined by the formalin-ether concentration method and 18·0% were found to be infected with one or more parasites. The infection rates of hookworm, Opisthorchis viverrini, Strongyloides stercoralis, Enterobius vermicularis, Ascaris lumbricoides, Hymenolepis nana, Capillaria philippinensis, Schistosoma japonicum, Echinostoma sp., Entamoeba coli, Giardia lamblia, and Entamoeba histolytica, were 7·6%, 7·0%, 3·2%, 0·5%, 0·3%, 0·1%, 0·1%, 0·l%,0·l%, 0·4%, 0·2%, and 0·1% respectively. The prevalence was highest among the 21–25 age group (24·8%). Among the 245 infected persons, 91% were infected with one parasite, 8% with two parasites and 1% with three parasites. The finding that parasitic infections are prevalent among Thai labourers demonstrates the need for control measures in foreign labourers in Taiwan and further studies to determine the susceptibility of O. viverrini to the snail hosts of Clonorchis sinensis.

Background: Consumption of raw or unhygienically prepared vegetables is a potential source of parasitic infection. This study aimed to establish the prevalence and types of intestinal parasites on the freshly sold vegetables at the market. Methods: Totally, 95 vegetable samples were randomly procured from vendors at Lusaka City market (Zambia). The samples were examined for parasitic contamination using floatation and sedimentation methods. Data were analyzed using Epi Info version 7.2.4.0. Results: The overall parasitic contamination of fresh vegetables was 35.8% (34 out of 95). The highest parasitic contamination rate was found in Chinese cabbage with 7.4% (7 out of 95), followed by rape with 6.3% (6 out of 95), chilli with 5.3% (5 out of 95), pigweed with 5.3% (5 out of 95), pumpkin leaves with 5.3% (5 out of 95), tomatoes with 4.2% (4 out of 95), and cabbage with 2.1% (2 out of 95). There was a significant (p=0.001) statistically difference between the type of vegetables and the presence of the parasites. The identified helminths had different prevalence rates, including Taenia spp. with 9.5%, Trichuris trichuria with 5.3%, Ascaris lumbricoides with 3.2%, Clonorchis sinensis with 2.1%, Diphyllobothrium latum with 2.1%, Paragonimus westermani with 2.1%, and Strongyloides stercoralis with 2.1%. Also, Giardia lamblia with 24.2% and Balantidium coli with 4.2% were the protozoan parasites identified. Conclusion: This study showed that some vegetables sold at the Lusaka City market (Zambia) were a potential source of parasitic infections for local consumers. G. lamblia was the most prevalent parasite found in the vegetable samples.

Status of intestinal parasitic infections among primary school children in Rivers State, Nigeria, was investigated between January and December 2011. A total of 3,826 stool samples were collected from school children (1,828 males and 1998 females) in 36 primary schools from 13 local government areas of Rivers State. The samples were analyzed using wet saline/iodine and formol ether concentration methods. Of the 3,826 stool samples examined, 1059 (27.66%) were positive for different intestinal parasites, namely,Ascaris lumbricoides(51.78%), hookworm sp. (25.0%),Trichuris trichiura(15.18%),Strongyloides stercoralis(7.14%),Taeniasp. (0.89%), andEnterobius vermicularis(0.01%). The prevalence of the infection was generally higher in males (57.60%) than females (42.40%). The differences were not statistically significant (P>0.05). Among these intestinal parasites,Ascaris lumbricoides, hookworm sp., andTrichuris trichiurawere found in all the 13 local government areas studied whileStrongyloides stercoraliswas found in 12,Taeniasp. in five, andEnterobius vermicularisin only one community in Ahoada Local Government Area. The overall infection rate remains high and would require coordinated deworming of the school children within the state.

Abstract Background A wide variation of causes can lead to gastrointestinal symptoms in children- an infection with parasites is one of them. The expansion of international travel might lead to an increase in testing children for a correspondent infection. Currently there are no guidelines available, which patients should be tested for a possible parasitical infection. The aim of the study was to characterize Swiss children suffering from intestinal parasites, in order to provide more knowledge for the clinician who should be tested. Methods This is a retrospective study of Swiss pediatric patients, whose stools have been tested for parasites and helminths. Results A total of 1855 stool samples, belonging to 572 different children with an average age of 7.9 years, were tested within a 10-year period. The prevalence of a positive result was 4.2%, of which all were positive for Blastocystis, and 12.5% had a co-infection with Endolimax nana. Conclusion Immigrants, immune compromised children with diarrhea and pediatric patients with bloody or protracted diarrhea should have 2 different stool specimens examined for a possible parasitical infection.

AbstractThis cross-sectional study aimed to determine the prevalence and risk factors of S. stercoralis infection among 1142 Orang Asli primary schoolchildren in six different states of Peninsular Malaysia. Fecal samples were examined using direct smear, formalin-ether sedimentation (FES), agar plate culture (APC) and PCR techniques. Overall, 15.8% of the children were found to be infected with S. stercoralis. The prevalence was 0.2, 1.3, 15.2 and 13.7% by direct smear, FES, APC and PCR, respectively. Multivariate analysis showed that an age of >10 years, being male, belonging to a Proto-Malay tribe, belonging to the Senoi tribe, indiscriminate defecation, using an unimproved water source for drinking water and not wearing shoes when outside were the significant risk factors of infection among these children. In conclusion, we provide new evidence on the occurrence of S. stercoralis in Malaysia to show that there is a relatively high prevalence of infection among Orang Asli schoolchildren. Therefore, the use of specific methods for detecting S. stercoralis should be considered when screening these children for intestinal parasites. Moreover, prevention and control measures specific to S. stercoralis should be integrated into the intestinal parasitic infections control programme in Malaysia.

Background. Neglected tropical diseases continue to be one of the leading causes of morbidity and mortality in the developing world. Psychiatric patients are among groups at risk for parasitic infection although control and monitoring programs largely overlook this population. This study aimed at determining prevalence and factors associated with intestinal parasitic infection among patients admitted to a psychiatric facility.Method. The study followed cross-sectional design; all the residing patients that met the inclusion criteria were included in the survey. Stool samples were collected and examined by direct wet preparation and formol-ether concentration. Data were analyzed with STATA version 12.1; Chi-square test was computed to determine the level of significance atpvalue < 0.05.Results.Of all 233 patients who returned the stool samples, 29 (12.45%) screened were positive for an intestinal parasite. There was no significant association between parasite carriage and age, sex, or duration of hospital stay.Conclusion. The study shows that intestinal parasitic infection is common among patients in a psychiatric facility and highlights that parasitic infections that enter through skin penetration may be a more common mode of transmission than the oral route. Furthermore, the study underscores the need for surveillance and intervention programs to control and manage these infections.

Abstract Intestinal parasitic infections in immunocompromised patients can lead to serious complications when not diagnosed and treated early. This study aimed to investigate the frequency of intestinal parasites in cancer patients undergoing chemotherapy in the South of Brazil. Three fecal samples collected from each patient (73 individuals) were processed by Ritchie and Faust techniques and submitted to specific staining methods for intestinal protozoa. A 61.6% parasite and/or commensal positivity was found. Helminths identified were Ascaris lumbricoides (33.3%), Taenia spp. (6.6%), Strongyloides stercoralis (4.4%) and Trichuris trichiura (2.2%). Among protozoans, Giardia lamblia (26.6%), Cryptosporidium spp. (13.3%) and Cystoisospora belli (4.4%) were identified. The presence of Entamoeba coli, Endolimax nana and Entamoeba hartmanni was also recorded. The results obtained warn of the importance of fecal parasitological diagnosis and the use of specific staining methods for the detection of intestinal parasites in cancer patients. These exams should be regularly requested at the patient’s first clinic visit, given the high prevalence found in this study and the possible severity of such conditions for these individuals.

Intestinal Parasitosis

Introduction: Nowadays in our state, intestinal parasitic diseases are still endemic, with a greater frequency in rural and mountainous urban areas. After the years have elapsed since the last national survey, it was necessary to carry out a new survey to know the prevalence rates of intestinal parasitosis and to compare the results obtained between both studies. Such knowledge would be of great value in developing health strategies and designing intestinal parasitic infection control programs. Objective: to determine the current prevalence rates of intestinal parasites, to compare the results with those of the survey obtained. Methods: a random cross-sectional descriptive study was carried out during the months of December 2018 to March 2019 in a random sample of both sexes from the population of urban communities and the province of Zacatecas, Zac. Each one had a stool sample collected that was analyzed by the direct examination method, the Willis concentration technique, and the Kato-Katz examination; A questionnaire was also applied to them. Results: when comparing the results of the national and state surveys of intestinal parasitic infections carried out in 2009 and 2018, it was found that, in general, infections by parasites decreased, both helminths and pathogenic protozoa, although those infected with commensals increased their frequency in that of 2019. There was also a decrease in the frequency of infections by all species of soil-transmitted helminths, Trichuris trichiura, Ascaris lumbricoides, ancylostomideos, and Strongyloides stercoralis, as well as by the pathogenic protozoa Giardia lamblia and Entamoeba histolitica. Conclusions: when comparing the results of national and state surveys of intestinal parasite infections carried out in 2018 and 2019, it was found that in general the frequencies of infections with intestinal parasites decreased. The finding in both studies of a higher frequency of infection with parasites or commensals in the group aged 5 to 14 years (school age), supports the recommendation to place emphasis on control programs for intestinal parasites in this age group.

Soil-transmitted helminths (STHs) are the most common intestinal parasites infecting humans worldwide. STH infections are a major cause of morbidity and disability. Accurate diagnostic tools are pivotal for assessing the exact prevalence of parasitic infections. Microscopic examination and culture techniques have been used to observe the presence of eggs or larvae of parasites in stool samples, but they are time-consuming and have low sensitivity. Therefore, accurate, simple, and inexpensive diagnostic techniques are still required for simultaneous detection of STH infections. Although molecular-based techniques, such as real-time PCR and multiplex real-time PCR, have been developed, they are not suitable for routine diagnosis due to the requirement for expensive reagents and instruments. In this study, we established a conventional multiplex PCR for simultaneous rapid detection of Ascaris lumbricoides, Necator americanus, and Strongyloides stercoralis in stool samples. Our results show that the multiplex PCR could detect the DNA of STHs at a very low target gene concentrations (lower than 1 pg) with no cross-amplification. Multiplex PCR had five times higher sensitivity than the formalin–ethyl acetate concentration technique (FECT) in the detection of multiple infections, and two times higher for detection of S. stercoralis. However, multiplex PCR was comparable to FECT in the detection of A. lumbricoides and N. americanus. In conclusion, this method could be used as an alternative method for the detection of STHs, especially for S. stercoralis.
