Although malaria is declining in many countries in Africa, malaria and anaemia remain frequent in children. This study was conducted to assess the relationship between malaria parasitaemia, intestinal worms, and anaemia, in children <5 years living in low transmission area in Senegal. A survey was carried out in 30 villages in the central part of Senegal. A two-level random cluster sampling technique was used to select study participant. Children <5 years were enrolled after informed consent. For each child, blood thick and smear tests were performed, haemoglobin concentration was measured with HemoCue, and stool samples were collected and examined using the Ritchie technique. A total of 736 children were recruited. Malaria parasite prevalence was 1.5% (0.7–2.6); anaemia was found in 53.4% (48.2–58.9), while intestinal parasites and stunting represented 26.2% (22.6–30.2) and 22% (18.6–25.5), respectively. In a logistic regression analysis, anaemia was significantly associated with malaria parasitaemia (aOR= 6.3 (1.5–53.5)) and stunting (aOR = 2 (1.2–3.1)); no association was found between intestinal parasites and anaemia. Malaria and anaemia remain closely associated even when malaria is declining. Scaling up antimalarial interventions may contribute to eliminate malaria and reduce the occurrence of anaemia among children.

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.

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 Background Intestinal parasitic infections are the most serious medical and public health problems in developing countries. In Ethiopia, intestinal parasites are among the top ten causes of morbidity, especially in children. The aim of this study was to assess the prevalence and associated factors of intestinal parasites among Ethiopian Orthodox church school students in Gondar town, northwest Ethiopia. Method: an institutional-based cross-sectional study was conducted to assess the prevalence and associated factors of intestinal parasites among religious students in Gondar town from February 2019 to April 2019, northwest Ethiopia. A total of 360 participants were selected by the random sampling technique. Results In this study, a total of 360 Orthodox Tewahido church school students were participated. The over all parasite prevalence, 24.7% was relatively low compared with previous studies conducted in other localitie in Ethiopia. The predominanat parasites were A. lumbricoides S. mansoni and hookworm with (11.4%), (4.4%) and (3.6%) prevalence respectively, A significant association was observed among participants with habits of frequent swiming with 2.3 times higher probability of acquaring infections, but there was no association with gender, age, finger nail status, the habit of eating uncooked vegetables/ fruits, source of drinking water and proper toilet utilization. Conclusion In general, the prevalence of intestinal parasite infections was high and calls for intervention actions on Orthodox Tewahido church students. Moreover, swimming frequency and habits had a significant association. Since the prevalence was high, improvement in awareness and enhancing health seeking behavior of the students, deworming and health education need to be focused on.

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.

The Difference

Microscopic examination of a wet mount of the stool has been the standard practice for the laboratory diagnosis of intestinal parasitic infections. Here we describe a novel method of stool microscopy of 80 stool samples, 31 (38.75%) were positive by the new thick stool smear wet mount method, whereas the corresponding figure for the conventional method using lacto-phenol cotton blue was 16 (20%). The difference was found to be statistically significant ( P<0.04 by McNemar's test). The thick stool smear wet mount procedure promises to be superior to the direct wet mount method in the detection of the intestinal parasites.

Introduction: Chronic spontaneous urticaria (CSU) which develops without a known stimulation is defined as the occurrence of spontaneous wheals, angioedema or both for longer than six weeks. Infections, autoimmunity, food intolerance and internal parasitic infections are supposed to be underlying causes of CSU. The aim of this study was to evaluate the intestinal parasites in children and adult patients diagnosed as CSU, to determine the frequency of parasites in chronic urticaria, and to compare these patients with healthy demographic control groups. Methodology: Seventy six children and 38 adult patients with CSU were examined in terms of parasitic infections. The patients whom parasites were detected received anti-parasitic therapy and the improvements in CSU symptoms were evaluated. Stool samples were examined with direct microscopic examination (native-lugol), stool concentration and trichrome staining methods. Results: In pediatric patient group, 18.4% (n = 14) of the stool samples were positive for Blastocystis sp., 2.6% (n = 2), Dientamoeba fragilis and 1.3% (n = 1), Giardia duodenalis. In adult patient group, Blastocystis sp. was detected in 18.4% (n = 7) of the stool samples. Anti-parasitic therapy yielded substantial improvement in urticaria symptoms in 57.1% of pediatric and 60.0% of adult patients. Conclusions: Blastocystis sp. and D. fragilis may play a role in chronic urticaria which seriously disrupts the patient's quality of life. Parasitic infections should not be neglected in patients with cutaneous manifestations.

Abstract Despite the low prevalence of parasitic infections in Europe, the diagnosis of intestinal parasites is difficult and laborious for microbiology laboratories. Currently, the antigens detection kits and the molecular biology have allowed an easier diagnosis. But these techniques have also limitations due to the fact that they do not detect all possible parasites presents in the samples. The objective of the study was to evaluate the accuracy and the usefulness of SediMAX2® (77 Elektronika, Budapest, Hungary) automated microscopy in the detection of parasitic structures from feces. A total of 197 formol-fixed stool samples were processed in parallel with wet mount examination and by SediMAX2®. Sensitivities, specificities and predictive values were analyzed, reaching sensitivity of 89.51% and specificity of 98.15%. Predictive values were also calculated with a very good positive predictive value (99.22%). SediMAX2® is a good tool for a reliable diagnosis of intestinal parasitic infections. The easiness of use, processing and the flexibility in the images analyse allows its incorporation in the day to day laboratory work as an extra step for the parasitologists workload.

Background: Intestinal parasitic infections are important public health problem and are globally endemic. These parasites are responsible for the major share of morbidity and mortality in those communities where there is overcrowding, poor environmental sanitation and personal hygienic practices. Intestinal parasitic infection is highly prevalent among the general population in Nepal. This study was aimed to evaluate the burden of the intestinal parasitic infections and the pattern of distributions among patients attending in a tertiary care setting in Bharatpur, Nepal, over a period of one year (August 2017 to July 2018). Methods: Stool samples of patients received in the Microbiology laboratory, COMS that were subjected for routine stool investigations were included in this study. Naked eye physical examination, microscopic examination was carried out and parasites were identified in the received stool samples. The results were recorded, and data were entered into excel spreadsheet 2007. The percentages of the parasites present were calculated to find out the frequency and distribution. Results: A total of 1,558 fresh stool samples were screened, of which 20.60% (n=321) were positive for various intestinal parasites. Overall, helminthic infections (81.30%) were higher than protozoal infections (18.70%). On the whole, Ascaris lumbricoides showed higher prevalence (39.56%) followed by Ancylostoma duodenale (19.31%) and Giardia lamblia (9.97%).  17(1.09%) of the samples showed more than one parasite. Highest prevalence was seen in age group 15 to 25 years of age (27.40%). Conclusions: Parasitic infection is endemic. Apart from the early diagnosis and effective treatment, health education is a requisite to control infections in this area and awareness of sanitation to reduce and control parasitic infection.

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.
