Abstract The study aimed to compare the diagnostic performance of the Kato-Katz, formalin ether concentration method (FECM) and FLOTAC using Sheather's sugar solution (FS1), saturated sodium chloride (FS2) and zinc sulfate (FS7) for the diagnosis of intestinal parasites among school children, focusing on Schistosoma mansoni. Ninety fecal samples were examined using the above mentioned techniques. The overall infection rate was 87.7%. Concerning protozoa, FLOTAC (FS1 and FS2) and FECM detected nearly equal infection rates (43.3% and 44.4%, respectively) with very good agreement. Kato-Katz diagnosed the highest helminthic infection rate (57.8%) followed by FLOTAC FS7 (44.4%) and FECM showed the lowest helminthic infection rate (27.7%). As for S. mansoni, Kato-Katz showed an infection rate of 38.8% vs FLOTAC (22.2%) and FECM (11.1%). The three techniques detected the same infection rate (11.1%) with egg counts more than 72 eggs/gram of feces. The FLOTAC sensitivity and accuracy for the diagnosis of protozoa were 97% and 99%, respectively. Regarding helminths diagnosis, FLOTAC technique showed higher sensitivity (77%) and accuracy (87%) compared to FECM (48% sensitivity and 70% accuracy). Therefore, FLOTAC can be used synchronously or in replacement to other diagnostic techniques. This can strategically impact future control programmes of intestinal parasitic infections in limited resources settings.

Associated Risk Factors

This study was aimed to assess the prevalence and associated risk factors of intestinal parasitic infections in grade school children in Maksegnit, Northwest Ethiopia. Five species of intestinal parasites were identified with an overall prevalence of 155 (40.4%). Among these, Ascaris lumbricoides 122 (31.8%) and Entamoeba histolytica 18 (4.7%) were predominant. Of the total 155 (40.4%) positive individuals, 149 (39%) had a single infection and the rest 6 (1.6%) had double parasitic infections. Of the different variables assessed, age, gender, shoe wearing, and eating raw or undercooked vegetables were not significantly associated with the prevalence of intestinal parasites ( P > 0.05 ). However, a statistically significant association ( P < 0.05 ) was observed between infected children and variables including defecation habit (AOR = 0.216), cleanliness of fingernails (AOR = 0.146), drinking river water (AOR = 0.124), and hand washing habit after defecation (AOR = 0.236) ( P < 0.05 ). Regular deworming, education on personal hygiene, and environmental sanitation to both students and their parents shall be implemented to reduce the prevalence rate of intestinal parasitic infections in the study area.

Background and Objectives: Intestinal parasitic infections are highly prevalent in developing countries, contributing to high incidence of malnutrition and morbidity. This study aimed to fi nd the prevalence of intestinal parasitic infections and their association with nutritional status of children in Benue State, Nigeria. Methods: A cross sectional study conducted from January-June 2016, among 418 school children under-5 years of age. Anthropometric data, height-for-age, weight-for-height, and weight-for-age Z-scores from each child and fecal samples were collected and screened for intestinal parasites using standard laboratory methods. Results: Among the intestinal parasitic infections detected, the prevalence of E. histolytica was higher (51.0% and 29.0%) than all other parasites encountered in rural and urban pupils (P<0.05). Other parasites were Hookworm (46.2% and 24.8%); G. lamblia (11.5% and 8.6%); and T. trichiura (2.4% and 5.2%). The prevalence of stunting (HAZ<-2), in rural and urban pupils were 43.8% and 32.9%; 64.4% and 39.0% rural and urban pupils were underweight (WAZ<-2), while 30.3% and 24.3% were wasted (WHZ<-2). Infected children had signifi cantly (P<0.05) higher z-scores than the uninfected children. Conclusion and Global Health Implications: Benue State is among the Nigerian states with the highest burden of tropical diseases with a current plan of elimination implemented through mass drug administration. This study identify/evaluate some essential information that will support the planning and implementation of the State’s ongoing efforts.   Copyright © 2016 Tyoalumun et al.

Background: Intestinal parasitic infections (IPIs) have been still quite common in developing countries including Ethiopia, particularly in children with low socio-economic and poor living conditions. Previous studies in Ethiopia have shown high burden of intestinal parasitic infections among the primary school children. The effective prevention and control of parasitic infections require research work based on the identification of intestinal parasites including associated predisposing factors. Objective: The aim of the present study was to investigate the prevalence of common intestinal parasitic infections and predisposing factors among the asymptomatic primary school children. Methods: A school based cross- sectional study was conducted from September, 2019- January, 2020 and a total of 422 asymptomatic primary school children were involved in the study. Specimens of the stool samples were examined using the standard parasite and ova method. Direct microscopy using saline and iodine wet mount preparation was used to examine the presence of eggs and larvae of helminthes and trophozoites and cysts of protozoan parasites and formalin ether concentration method was used for quality assurance. Structured questionnaires were also used to collect quantitative data on socio-demographic characteristics and predisposing factors. Analysis of the data was made manually using the thematic framework method including descriptive statistics. Results: Among the 422 students (aged 5-14 years) participated in the study, 245(58%) were positive for one or more intestinal parasites. Of the total infected participants, 192(45.5%) were single infections and 53(12.6%) were double infections identified. Seven types of intestinal parasitic infections were identified in the present study. The most prevalent parasite was Giardia lamblia 95(22.5%) followed by hook worm 58(13.7%). Age groups 5-9 years old were more infected, 173 (70.6%) than age groups 10-14 years old 72(29.4%). This result also showed parasitic infections were associated with predisposing factors related to infectious cycles. Concluding Remarks and Recommendations: The present study revealed that there was a high prevalence of intestinal parasitic infection among students in the targeted primary schools. Therefore, all stakeholders should give attention to raise awareness about the prevention and control mechanisms of intestinal parasitic infections. Moreover, the health services of the local government should develop a habit of mass public health education and deworming intervention to improve the level of parasitic infection and environmental hygiene in the study area.

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.

SummaryThe aim of this study was to estimate the prevalence and distribution of species of intestinal parasites in the Balkans on the example of Kosovar and Serbian residents from the region of Gnjilane ineastern Kosovo,where the epidemiology of intestinal parasitic infections remains unknown. Parasitological examination of stools pecimens was performed in 2017 and 2018. Stool samples were collected from asymptomatic school-children aged 6–17 years: 530 Kosovars from the municipality of Kaçanik and310 Serbs from the municipalities of Kamenica and Strpce. Each patient provided two stool samples collected every second day,fixed in SAF preservative and 70 % spiritus vini, transported to the Department of Epidemiology and Tropical Medicine at the Military Institute of Medicine in Poland,and tested by light microscopy using three diagnostic methods: directs mearin Lugol’s solution,decantation in distilled water, and Fülleborn’s flotation. A total of 101 Kosovar children (19.1 % of the study group)were found to be infected with intestinal parasites: nematodes (n=20), cestodes (n=2), trematodes (n=2), and protozoa (n=79). Only 13 Serbian children (4.2 %) were found to beinfected with nematodes (n=4),cestodes (n=3),and protozoa (n=6). Giardia intestinalis was themost prevalent intestinal parasite in both groups (14,9 % vs. 1.9 % children). The prevalence ofasymptomatic parasitic infections was significantly higher in Kosovars in comparison to the Serbsliving in the same region of eastern Kosovo. This fact shows that there may be significant differencesin the quality of health care and sanitation as well as feed hygiene between these two communities.

Background and Objectives: Gastrointestinal infections impose a great and often silent burden of morbidity and mortality on poor populations in developing countries. School age children are one of the groups at high-risk for intestinal parasitic infections. The objective of this study was to compare the prevalence rate of intestinal helminthes parasites among private and public school children of Devdaha Municipality of Rupandehi district and to determine the association of prevalence with different risk factors. Material and methods: The study was carried out during June to July 2019. A total of 150 (75 from public and 75 from private school) stool samples were collected in clean, dry and screw capped plastic vials and were studied for the presence of intestinal helminthes parasites using direct smear method. Results: Overall parasitic prevalence rate was 18.66% (28/150). Prevalence rate was considerably higher in public school children (22.66%; 17/75) compared with private school (14.66%; 11/75) (P>0.05). The prevalence of helminthes parasitic infections was statistically independent with age and gender of the students (P>0.05). The current finding was maximum for single parasitic infection in both public (88.23%) and private (90.90%) school. Total four genera of parasites were identified. Among them, Ascaris lumbricoides was most common followed by Trichuris trichiura, Hookworms and Taenia sp. Conclusion: Transmissions of infections were generally due to poor sanitary habits, use of contaminated drinking water and improper disposal management. This study suggests the need of health education program in schools along with regular screening of intestinal parasites and periodic administration of anti-parasitic drugs for the effective management of the intestinal parasitic infections among school children in Nepal.

The burden of intestinal parasitic infections (IPIs) has been a common problem on children in Ethiopia. While communities in Bure town, northwest Ethiopia, are presumed to be exposed to IPIs, no study has been conducted before. The aim of this study was therefore to assess the prevalence of IPIs and associated risk factors among school children in Bure town by conducting a cross-sectional study from January to June 2019. A total of 430 students were selected using stratified systematic random sampling technique. Direct wet-mount and formal-ether concentration techniques were used for parasitological analysis from stool samples taken from each student. Information about the risk factors was collected using structured questionnaire. Data were analyzed using SPSS version 24. The overall prevalence of IPIs among the children involved in the study was found to be 40% (172/430). Some 37.7% of the students exhibited single parasite infection, 2.1% double and 0.23% triple parasite. Seven species of intestinal parasites were detected, and Entamoeba histolytica/dispar was the most prevalent parasite (22.1%) followed by Giardia lamblia (8.6%), hookworms (6.75%) and Ascaris lumbricoides (3.7%). Hymenolepis nana, Trichuris trichuira and Taenia species were rare  (<1% prevalence each). Knowledge about personal and food hygiene as well as environmental sanitation were the most important predictors for IPIs (P<0.05). Primary school children in Bure town are at high risk of IPIs. Awareness creation on personal hygiene and environmental sanitation is strongly recommended. Keywords: Intestinal parasitic infections; Prevalence; Primary school children; Risk factor; Bure town

The present study investigated the intestinal parasitic infections in schoolchildren of Kapan VDC, Kathmandu, Nepal. A total of 330 schoolchildren were included in this study. Stool samples collected in clean, dry, screw-capped plastic containers were examined by formal-ether sedimentation technique. A total of 134 samples (40.6%) were positive for some kind of intestinal parasites. The percentage of monoparasitism (67.9%) were higher than multiparasitism (32.1%). Giardia lamblia (17.8%) and Trichuris trichiura (3.6%) were the commonest protozoa and helminthes respectively. Girls were marginally more infected (41.4%) than boys (39.8%) (p>0.05). Children <5 years were more infected (80.0%) than 5-10 years (36.0%) (p=0.001). Prevalence of parasitic infection rate was higher in family size >5 (41.5%) than ≤5 (40.1%) (p=0.82). In ethnic wise distribution, incidence rate of parasites was higher in Dalits (71.4%) and the least in Indo-Aryans (33.1%) (p<0.05). Children drinking water from groundwater source had marginally lower prevalence rate (31.3%) than who used tap water (58.4%) (p<0.001). The higher infection rate (51.3%) was observed in children belonging to labour family and the least in the business family (33.3%) (p=0.032). The children who had taken anti-parasitic drug within past 6 months had lower prevalence rate (25%) than those who had not taken drugs (44.4%) (p=0.005). Int. J. Appl. Sci. Biotechnol.

Diarrhoea is an important cause of malnutrition, morbidity and mortality among children in Yemen. Coccidian parasitic infections are an important cause of diarrhea in children particularly malnutrition and immune-compromised patients, but their investigations are rarely required by the treating physicians in apparently immunocompetent children. This study was aimed to find the prevalence of intestinal coccidian parasites in country with high incidence rate of malnutrition. Between May 2016 and October 2016, 228 fecal samples from 228 selected school children in Al Turbah city, Taiz governorate, Yemen, aged between 6 and 15 years were examined using wet-mount preparations and formal concentration method then films stained by modified acid-fast staining. Also data of children were collected including demographic data, and sources of water. Findings of positive intestinal coccidian parasites were analyzed in relation with demographic data, and sources of water.  The prevalence of Cryptosporidium species, Cyclospora species and Isospora belli were 75.9%, 45.6% and 1.75% respectively. There was significant association between positive of Cryptosporidium species and females (OR= 2.1 times, P=0.01), and spring water source (OR=4 times, P=0.04), while there was no significant association between positive of Cryptosporidium species and others factors studied. Also there was no significant association between positive of Cyclospora species and Isospora belli and children sex, age groups, or different sources of water. In conclusion the study highlights the high prevalence of coccidian parasites among immunocompetent school children in Yemen. The clinicians in Yemen need to be aware that coccidian parasites are a potential cause of childhood diarrhea even in immunocompetent children.

Intestinal Parasitic Infections

Intestinal parasitic infections (IPI) such as soil transmitted helminths (STH) and protozoa can cause diverse negative effects on human health. The prevalence of IPI in primary school children in Mbeere North sub-county in Embu County is not documented, though there are many cases reported in health centers in the area. The aim of this study was to establish the current prevalence of IPIs in primary school children in Mbeere North sub-county and the factors that perpetuate transmission which is necessary for implementation of suitable control programs in the study area. The study was done among primary school children from nine public schools. Three schools per administrative ward were randomly selected to represent each of the three administrative wards. A total of 414 pupils whose parents/guardians gave informed consent participated in the study, 46 pupils per school. Each participant provided a thumb size of early morning stool. The stool samples were processed by Formol-ether concentration technique and direct wet preparation methods for microscopic identification of intestinal parasites. A structured questionnaire was used to collect data on age, sex, sanitation and hygiene practices. The overall point prevalence of intestinal parasitic infections amongst the pupils was 43%. Chi-square (χ²) test was done to determine the relationship between prevalence and the pupils’ age and sex. There was no significant association between prevalence and sex (χ² = 0.184, P = 0.668, df = 1) but a significant association was found between prevalence and age where children 11 years and below were more pre-disposed than those above 11 years old (χ² =4.770, P=0.043, df =1). Similarly, a significant association was found between water source and prevalence of IPI; the parasites infection prevalence decreased when tap water was used and increased when open surface water was used (F = 6.15, P = 0.006). From this study, it is clear that IPIs particularly E. histolytica are a problem in primary school children in Mbeere North Sub-County. There is an urgent need for provision of safe domestic water in the county. Additionally, community education on sanitation and IPI transmission risk factors is urgently required. The information generated in this study is beneficial to the public health service in designing control strategies for areas of high transmission.
