Background. Intestinal parasite, Salmonella, and Shigella infections are the main public health concerns in the world, especially in developing countries due to inaccessibility of safe water and unhygienic food handling practices of food handlers. Methods. A cross-sectional study was conducted in food handlers in Motta town, from February 2019 to April 2019. The study was undertaken to determine the prevalence and associated risk factors of Salmonella, Shigella, and intestinal parasites among 243 food handlers. Sociodemographic and risk factors were collected using pretested structured questionnaire. The stool sample was collected and examined with direct wet mount and concentration techniques. Culture was performed using xylose lysine deoxycholate agar and MacConkey agar and biochemical tests like Klinger iron agar (KIA), lysine iron agar (LIA), Simmons citrate agar, sulphide indole motility test, citrate utilization, and urease production test were conducted to isolate Salmonella species and Shigella species. An antibiotics susceptibility test was performed with Mueller-Hinton agar using the disk diffusion method. Data were entered using statistical package Epi-Data Version 3.1 and analysed with logistic regression using SPSS version 25 and Fisher’s exact test. A p value < 0.05 at 95% CI was considered as statistically significant. Results. The prevalence of intestinal parasite, Salmonella, and Shigella was 27.6%, 2.5%, and 1.6%, respectively, and hookworm was the predominant intestinal parasite detected in the stool. Antimicrobial resistance was observed in ampicillin and tetracycline (100%) in Salmonella species and Shigella species. Risk factors like fingernail status, fruit washing before eating, cleaning utensils, and regular shoe wearing habit were associated with intestinal parasite, whereas fingernail status and wearing kitchen gown during food service were significantly associated with Salmonella and Shigella infections. Conclusion. The prevalence of intestinal parasitic infections, Salmonella, and Shigella infections in this study indicates the importance of food handlers as probable sources of enteropathogenic infections. Food handlers should have follow-up on the order of food safety rules and keep their personal hygiene. Hotel owners are responsible to control the health status and their created awareness by given food hygiene training for food handlers. Therefore, policy-makers and implementers should focus on the risk factors to reduce the prevalence below the level of public health importance.

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.

Food handlers are important sources of intestinal parasitic infection to the public and mass catering service areas. Several reports worldwide particularly in developing countries showed a high prevalence of intestinal parasitic infections among these groups of individuals. In an attempt to determine the prevalence of intestinal parasites, a cross-sectional study was carried out among food handlers in food establishment areas of Mettu town, Southwest Ethiopia. To collect sociodemographic characteristics of the study participants, a structured questionnaire and physical observation were employed. Stool specimens collected from each food handlers participated in the study were then examined using light microscopy of the wet mount followed by formol-ether concentration methods to see infection status. A total of 139 food handlers were enrolled in the study. Majority of them were females 89 (64%), and 124 (89.2%) of them had not taken any training related to food handling and preparation. Sixty-two (44.6%) of the study participants were diagnosed with one or more intestinal parasites. The chi-square test showed that intestinal parasite infection was found associated with personal hygiene ( p  ≤ 0.0001), nail trimming status ( p  ≤ 0.0001), and hair cover status ( p  ≤ 0.040). The multivariable logistic regression indicated that the risk to be infected with intestinal parasites were related with older age ( p  ≤ 0.032), food handlers who had no hand wash practices ( p  ≤ 0.033), who had no food handling and preparation training ( p  ≤ 0.005), poor personal hygiene ( p  ≤ 0.0001), who had not taken regular medical checkup ( p  ≤ 0.008), and whose nail was not trimmed ( p  ≤ 0.0001). The most abundant intestinal parasite identified was G. lamblia (24, 26.7%) followed by E. histolytica/dispar (22, 24.4%), and A. lumbricoides (15, 16.7%). Twenty-eight (45.2%) study individuals were also found with mixed infections. The study thus revealed a high prevalence of intestinal parasitic infection among apparently healthy food handlers in food establishments of the study area. Mass drug administration for all food handlers working in food establishment areas of the town coupled with health education and training should be initiated urgently.

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

Background Intestinal parasitic infections are still a serious public health problem in poor and developing countries like Ethiopia. Local epidemiological data is crucial to design and monitor prevention and control strategies. This study aimed to determine the prevalence of intestinal parasite infections and associated risk factors among patients requested for stool examination at Jimma health center, Southwest, Ethiopia. Methods A cross-sectional study was conducted among a total of 384 patients in Jimma health center, Southwest, Ethiopia. Stool samples were collected and examined using direct wet-mount and formal-ether concentration techniques. Data were analyzed using the Chi-Square (X2) test and SPPS Version 24 and P Value<0.05 was considered for statistically significance. Results The overall prevalence of intestinal parasite infections was found to be 79(20.6%). The infection rate was slightly higher in females 261(68%) than in males 123(32%). Eight types of intestinal parasites were identified and the highest prevalence was Giardia lamblia 25(6.5%) followed by A. lumbricoides 22(5.7%). Single parasitic infection was found among 67(17.4%) of the patients and double infection was 12(3.1%). Shoe wearing habits, Status of fingernail, Handwashing before a meal and after defecation, Source of water for bathing and drinking were significant factors(p<0.05) for intestinal parasitic infection. Conclusion A relatively low prevalence of intestinal parasite infections was observed among patients of Jimma health center requested for the stool examination.

Background: Parasitic infections, especially intestinal agents could affect social and personal hygiene and health; and to avoid the spread of pollution, monitoring the infectious sources is critical. Objective: The aim of this study is to estimate the prevalence of intestinal parasites and identify factors associated with intestinal parasitic infections among students of Jahrom University of Medical Sciences between 2013-1014. Materials and Methods: This study was carried out between September 2013and February 2014. A total number of 1293 stool samples were taken from 431 students and were examined by direct wet mounting and formalin-ether methods. A questionnaire for common risk factors was completed for each individual. Results: Overall, the prevalence of intestinal parasitic infections was estimated to be 125 (29%) that infected by pathogenic and non-pathogenic intestinal parasites. Various species of protozoan infections were detected: Entamoeba coli was the most common parasite (9.04%) followed by Blastocystis hominis (8.12%), and Giardia lamblia (4.64%). About 3.2% students were infected with multiple parasites. A significant association was observed between the prevalence of intestinal parasite infections with the type of accommodation (OR=1. 5; 95% CI: 1.1; 1.9), parents’ educational level (OR=1. 5; 95% CI: 1.1; 1.9) and gender (OR=1. 5; 95% CI: 1.1; 1.9). No age association was detected, and a slightly positive prevalence with increasing age was observed (p=0.66). Conclusions: These data showed intestinal parasites were slightly more prevalent than expected, that might be due to interior sources of infection in college, such as carrier students. Hence, performing periodic monitoring among students is a necessity to promote the hygiene of the students.

BackgroundIntestinal parasites are a major public health problem in the developing world and have attracted increasing levels of interest from health researchers over the past decade. Epidemiology-based studies have shown that the prevalence of intestinal parasites is high and they frequently recur in regions with poor sanitation and inadequate sewerage facilities. In this study, we determined the prevalence of intestinal parasites, their egg intensities per sample, and associated risk factors in an informal settlement.MethodsThis was a cross-sectional study conducted in three randomly selected public primary schools located in the informal settlements of Nakuru town. A total of 248 stool samples were collected from asymptomatic pupils and screened, using the Kato Katz technique, for infections caused by soil-transmitted helminths (STH). A random subset of stool samples (n=96) was also screened by polymerase chain reaction (PCR) to detect intestinal protozoa. Socio-demographic variables were collected using a pre-tested structured questionnaire; these data were analysed to identify risk factors for infection. ResultsThe overall prevalence of intestinal parasites was 17.3% (43/248 pupils). The overall prevalence of both STH and intestinal protozoan parasites was 1.2% and 41.7%, respectively. The most commonly diagnosed STH infection was Trichuris trichiura (1.2%), followed by hookworms (0.4%) and Ascaris lumbricoides (0.4%). The prevalence of intestinal protozoan parasites ranged from 0% to 38.5% and included Entamoeba histolytica, Entamoeba hartmanni, Entamoeba dispar, Giardia intestinalis, and Entamoeba coli. All infections were light, with an egg intensity <100 for each of the STH infections. The prevalence of multiple infections, including intestinal protozoan parasites, was 5.2% (n=5) and 0.4% (n=1) for STH in the subset samples. Finally, our analysis identified several significant risk factors for intestinal parasitic infections, including goat rearing (p=0.046), living in a home with an earthen floor (p=0.022), the number of rooms in the household (p=0.035), and the source of food (p=0.016). ConclusionThe low prevalence of intestinal parasites in the informal settlements of Nakuru may be attributed to improvements in hygiene and sanitation, deworming, and general good health practices that are facilitated by the Department of Public Health.

Abstract: Objective: Pathogenic species of protozoa and helminth cause intestinal parasitosis, which continues to be a significant community well-being issue in many regions of the world, especially in pastoral regions of developing countries like Nepal. The study focused on determining the prevalence of intestinal parasitic infections and the associated risk factors among the people of the Chepang community of the Saktikhor area in the Chitwan district. Materials and Methods: A transversal study was conducted between May 2017 and October 2017, with a total of 125 participants. The fecal samples were examined using a wet media (saline media, iodine preparation), concentration and sucrose flotation method. The association between risk factors and parasitic prevalence was evaluated using the Pearson’s chi-square test. Results: The general prevalence of intestinal parasite infection was 52%. Infections with soil-borne helminth were more common than those with cestodes and protozoa. Common intestinal parasites included Ascaris lumbricoides (69.23%), Trichuris trichiura (9.23%), Hookworm (7.69%), Strongyloides stercoralis (4.62%), Hymenolepis nana (6.15%), Taenia sp. (6.15%), and Entamoeba coli (9.23%). High prevalence of infection was observed among male (53.96% ) participants and those aged over 20 years (69.44%). Pearson's chi-square test revealed a substantial relationship between prevalence of parasite and age group (P=0.0452), hand washing material (P<0.001) and preference for defecation site (P<0.001). Conclusion: Hence, a heavy occurrence of intestinal parasites within the Chepang community is particularly evident. There is a need for increased emphasis on intrusion, which can be achieved by improving personal hygiene and sanitation of participants and constructing proper sanitary toilets to prevent the spread of parasitic infections.

Intestinal parasitic infections (IPIs) have been major public health burdens in low-income countries like Ethiopia. Studies in different areas of Ethiopia have shown a high prevalence of IPIs in poor families. A similar study has not been conducted in Sasiga District given that the area is possibly at high-risk of IPIs due to the prevailing risk factors. This study is aimed at assessing the prevalence of IPIs and associated risk factors among schoolchildren in Sasiga District, southwest Ethiopia. A school-based cross-sectional study was conducted from December 2018 to March 2019 to estimate the prevalence of IPIs and associated risk factors among the study participants. A total of 383 children were selected using resident-type and grade-level stratified systematic random sampling technique. Stool samples were examined microscopically using direct wet mount and formal-ether concentration techniques. A structured questionnaire was used to get information on the associated risk factors. Data were analyzed using SPSS version 20 and p value of ≤0.05 was taken as statistically significant. The overall prevalence of IPIs among the children was 62.4% (239/383). Single, double, and triple infections were 49.9%, 10.7%, and 1.83%, respectively. Residence, family income, place of defecation, source of drinking water, shoe-wearing habit, handwashing habit after toilet use, ways of waste disposal, and cleanliness of fingernail were the most important predictors of IPIs (p<0.05). Ascaris lumbricoides (22.7% (87/383)) and hookworms (20.6% (79/383)) were the most prevalent parasites, followed by Entamoeba histolytica (8.1%), Trichuris trichiura (7.6%), Giardia intestinalis (6.5%), Hymenolepis nana (5.7%), and Schistosoma mansoni (4.4%), in that order. Sasiga District primary schoolchildren are likely at a high burden of IPIs. Intensive health education on personal hygiene and environmental sanitation is needed.

Abstract Background Determination of the prevalence and distribution pattern of intestinal parasites is a fundamental step to set up an effective control program to improve the health status. This study aimed to determine the prevalence of intestinal parasitic infections and associated risk factors among inhabitants of Rudbar-e Jonub county, southeast of Kerman province, southeastern Iran.Methods In this cross-sectional study, 861 stool specimens were collected from inhabitants of Rudbar-e Jonub county through a multistage cluster sampling method in 2018. The collected specimens were examined by parasitological methods including, direct wet-mounting (for the fresh specimens with a watery consistency), formalin-ethyl acetate sedimentation and agar plate culture.Results The prevalence of intestinal parasites was 34.2% (95% CI 30.1 to 38.2). The prevalence of protozoan parasites 32.3% (95% CI 28.4 to 36.5) was significantly higher than helminthic parasites 3.2% (95% CI 2.1 to 4.7). Blastocystis sp. , Entamoeba coli and Giardia lamblia as protozoan parasite and Hymenolepis nana as helminthic parasite were the most common detected intestinal parasites in the study. Entamoeba histolytica/dispar , Iodamoeba bütschlii , Chilomastix mesnili , Entamoeba hartmanni , Ascaris lambercoides , and Enterobius vermicularis were other detected parasites. Multiple logistic regression revealed a significant association of intestinal parasitic infections with source of drinking water and residency status (rural/urban). Multiple infections with 2 or 3 parasitic agents constituted 22.7% of 295 infected cases.Conclusions This study revealed a high prevalence of intestinal protozoan infections among inhabitants of Rudbar-e Jonub county. Intestinal parasites especially protozoans remain a challenging public health problem wherever sanitation and health measures are limited in Iran.

Background:  Infections by intestinal pathogens especially protozoans and helminths are considered to pose a real health problem, particularly in the tropics.  They cause considerable morbidity and mortality rates in developing countries. The high prevalence of these infections is closely correlated with poverty, poor environmental hygiene, and impoverished health services. This study aimed to detect prevalence and frequency of parasitic infections among food handlers in Khartoum Sudan.  Methods: Three hundred and fifty Food-handlers, attending public health laboratories in Khartoum, Sudan, for an annual medical check-up, were screened for intestinal parasites by four laboratory techniques viz. direct faecal examination, formal-ether concentration, Baermann technique and agar culture method. Results: The infection rate was 23.7% by Formol-Ether Concentration technique, followed by direct saline stool preparation (7.1%). Out of 83 positive samples the infection rate among different nationalities was as follows: Sudanese 68 (81.9%), Ethiopians 13 (15.7%), Syrians 2 (2.4%) and Egyptians 0 (0%). Intestinal parasites were more prevalent among males (73; 25.1%) than female food handlers (10; 16.9%). Three protozoans, nematodes, two tap worms and one trematode worm were detected among infected population: their frequency were as follows: Entamoeba histolytica (7.4%), Entamoeba coli (6.86%), Giardia lamblia (6%), Schistosoma mansoni (1.40%), Necator americanus (1.43%), Hymenolepis nana (0.68%), Strongyloides stercoralis (0.68%), Taenia saginata (0.57%), Ascaris lumbricoides (0.57%) and Trichostrongylus species (0.29%). Conclusion: The overall prevalence of protozoan infections among food handler in Khartoum state, Sudan was 20.26% while the helminthic infections was 5.97%. Formol-ether concentration technique is better for detection of intestinal parasites than the direct faecal smear technique. Likewise, Barmann’s technique confirms detection of nematodes worms especially hookworms.
