Rhesus macaques (Macaca mulatta) are hosts to a range of zoonotic and potentially zoonotic pathogens. The present study firstly provides a broader investigation of the presence and prevalence of zoonotic fecal pathogens in wild Taihangshan macaques, a subspecies of rhesus macaque in China. A total of 458 fecal samples were collected between September 2015 and November 2016. Fourteen genera of intestinal parasites (four genera of protozoans and ten genera of helminths) and twelve genera of bacteria were tested for using PCR amplification. The overall samples prevalence of parasitic infection was 98.25%. Entamoeba spp. (89.96%), Balantidium coli (70.09%), and Isospora spp. (28.38%) were the most prevalent protozoa, whereas the predominant prevalent helminths were Trichuris sp. (93.23%), Strongyloides spp. (73.36%), and Oesophagostomum sp. (31.66%). Ten genera of intestinal bacteria were detected in samples of rhesus macaques, including Shigella (31.66%), Escherichia coli (29.91%), Klebsiella pneumoniae (28.38%), Leptospira (26.64%), Campylobacter jejuni (18.34%), Salmonella (13.32%), etc. Eight samples (1.75%) were tested Hafnia-positive based on sequences analysis of 16S rRNA and ampC gene. This is the first molecular characterization of Hafnia infection in NHPs. Our cross-sectional prevalence study provides important information for monitoring the potential transmission of zoonotic infections from wild rhesus macaques.

Background: Intestinal parasitic infections are the one of the most common health problems in developing countries. Objective: A number of patients die annually due to complications caused by these parasites.Therefore, the aim of this study was to investigate the rate and type of parasitic infections, determine the factors affecting them in Ilam city and also provide strategies to prevent them.In this descriptive cross-sectional study conducted in one of the Ilam labs in 2016, 417 stool specimens were randomly collected. All specimens were examined using direct and ethanol formaldehyde.Suspect specimens were examined using Trichrom staining. Demographic information was also recorded in a questionnaire, and finally the results were analyzed using statistical software SPSS 20.The data were then compared with Chi-square test. Results: Out of the 417 patients examined, 59 (14.1%) were infected with intestinal parasites. The type of parasitic infection in 9.4% was Blastocystis hominis, 3.6% Entamoeba coli, 0.5% Entamoeba histolytica, 0.5% Giardia and 0.2% Trichomonas hominis. Conclusion: Despite the improvement of public health, parasitic infections are still considered as one of the health problems in the city of Ilam. Therefore, proper planning, public health education, raising the level of health in the area and the provision of safe drinking water are some of the ways to reduce parasitic infections in the region.

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.

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.

Abstract Background: Parasitic infections are known causes of morbidity among HIV infected patients with low CD4+ counts who are on antiretroviral therapy; mainly as a result of immune suppression. Thus, this study aimed to assess the extent of intestinal parasitic infection and its related risk factors among HIV infected patients attending ART clinic of Debretabor General Hospital, Northern Ethiopia.Patients and methods: A health facility based cross sectional study was conducted on a total of 383 HIV infected patients attending ART clinic of Debretabor General Hospital, Northern Ethiopia from December 2018 to March 2019. An interview based structured questionnaire were used to gather socio-demographic and risk factor data. About 5 grams of fresh stool specimen and 4 ml of venous blood sample were collected, then transported and tested in accordance with the laboratory standard operating procedures. The obtained data was entered into SPSS version 22.0; and analyzed. P-value <0.05 with 95% confidence interval was considered statistically significant.Result: The overall prevalence of intestinal parasites was 25.3%; with 18% and 23.8% by direct wet mount and formol-ether concentration technique respectively. 8 (2.1%) patients were infected by multiple parasites in concentration technique. Ascaris lumbricoides, 23(25.3%) was the most frequently identified parasite. Parasitic infection was significantly higher among illiterates (P=0.011); patients with a CD4 count of <200 cells/mm3 (P<0.001) and among patients who did not have latrine (P=0.049) than their counter parts.Conclusion: Relatively higher prevalence of intestinal parasitic infection was found among HIV/AIDS patients. The distribution of intestinal parasites is greatly affected by illiteracy, reduced CD4+ counts and absence of toilet. Thus, HIV/AIDS patients with low CD4+ counts should be diagnosed consistently for intestinal parasites and routine stool examination and awareness creation should be advocated to be included as an essential component of the ART monitoring strategy for improved patient care.

Abstract Background Intestinal parasitic infection is one of the parasitic infections affecting people living in prison. Helminths and intestinal protozoan infections are the most common parasitic infection that may cause serious life-threatening diseases in inmates living in developing countries. This study was aimed to investigate the prevalence and associated factors of intestinal parasitic infections (IPIs) among inmates living in Arba Minch prison, southern Ethiopia. Methods Institutional based cross sectional study was conducted on Arba Minch inmates, southern Ethiopian. Pre-tested semi-structured questionnaire was used to gather the data of socio-demographic characteristics, hygiene status of the prisoners, sanitation condition of the prison, and associated factors for IPIs by face to face interview. Direct wet-mount examination and formol-ether sedimentation techniques were used to examine intestinal parasitic infection from stool specimens. Binary logistic regression analysis was used to see the association between different variables and the IPI. Odds ratio with 95% CI was computed to determine the presence association and strength of the associated factors. Result A total of 320 prisoners were participated in this study. Of these, 154(48.1%) of them were infected with one or more intestinal parasites. Eight different intestinal parasites species were identified and Giardia lamblia was the predominant parasite. Among infected inmates, nearly one out of four of them had multiple parasitic infections dominated by Giardia lamblia and E. histolytica/dispar co-infection. Sleeping in group [AOR = 1.9; 95% CI: (1.0–3.8)], married prisoners [AOR = 1.8; 95% CI: (1.1–2.9)], and hand washing habits after handling soil [AOR = 2.4; 95% CI: (1.0–5.6)] were independently associated with IPI. Conclusion High prevalence of intestinal parasitic infection was detected in Arba Minch inmates, southern Ethiopian. Absence of hand washing, marital status, and way of sleeping were the factors associated with the IPI. Implementation of mass drug administration, education on water, sanitation and hygiene (WASH) and periodic screening of intestinal parasitic infection is very important to reduce the high prevalence IPIs in prison.

Data concerning the burden of parasites among populations living in overcrowded circumstances have paramount importance for the success of interventions aimed at eliminating such disease. A cross-sectional study was therefore conducted from February to May 2019 among 217 children at child centres in Bahir Dar city. Data were collected using a structured questionnaire and stool samples were processed for parasitological investigation. A total of 53 (24.4%) children were infected with at least a single species of intestinal parasite. Giardia lamblia (7.8%) was the most frequent, followed by Hymenolepis nana (6%). Children with untrimmed fingernails (adjusted odds ratio [AOR] = 2.422, P = 0.027) were significantly more prone to infection. Similarly, children with no habit of hand washing after soil contact (AOR = 2.752, P = 0.014) or after defecation (AOR = 3.087, P = 0.026) were significantly associated with parasitic infection. The prevalence of intestinal parasites at child centres in Bahir Dar is of public health importance; therefore, control programmes should target these children.

Background. Intestinal parasitic infection is one of the major health problems globally. It is more common in developing countries including Ethiopia. So, adequate evidence is needed regarding the predictors of intestinal parasitic infection. This study was aimed at determining the predictors of intestinal parasitic infection among food handlers working in Madda Walabu University, Ethiopia. Methods. An institution-based cross-sectional study was conducted from 15 May to 10 June 2017 among 198 symptom-free food handlers. Data on sociodemographic variables were collected through face-to-face interview using a structured questionnaire. Stool samples were collected immediately after the interview using labeled wide-mouthed plastic container and clean wooden applicator. Direct wet-mount method and formal-ether concentration techniques were performed to identify intestinal parasites. The data were analyzed using SPSS version 21.0. Descriptive statistics and crude and adjusted odds ratios with 95% confidence interval (CI) were calculated. p value of <0.05 was considered to declaration level of significance. Result. The response rate was 98% (198/202). The overall prevalence of intestinal parasites was 25.3% (50/198). The top three intestinal parasites found in this study were Ascaris lumbricoides 7.6% (15/198), Entamoeba histolytica/dispar 7.6% (15/198), and hookworm 5.6% (11/198). Inadequate handwashing practice (AOR: 13.876; 95% CI: 4.129, 46.632), inadequate knowledge about foodborne diseases (AOR: 3.596; 95% CI: 1.438, 8.989), lack of training on proper food handling (AOR: 5.960; 95% CI: 1.450, 24.497), and untrimmed fingernail (AOR: 2.939; 95% CI: 1.368, 6.135) were independent predictors of intestinal parasitic infection. Conclusion. High prevalence of intestinal parasites was observed among symptom-free food handlers who could be unobservable source of disease transmission. Inadequate handwashing, untrimmed fingernail, inadequate knowledge, and lack of training were independent predictors of intestinal parasitic infection in this study. This implies the need for timely and adequate training and enforcement of regular medical checkup system for food handlers.

Background: The present study aimed to evaluate the prevalence of intestinal parasitic infection among mentally retarded individuals and the staff of the center in Bandar Abbas, south of Iran. Methods: This cross-sectional study was conducted in central institution for mentally retarded in Bandar Abbas, Hormozgan Province, from 2016 to 2017. A triple fecal specimen was collected from each one of the 163 participants and were evaluated using wet mount and formalin-ethyl acetate methods. Trichrome and Ziehl-Neelsen staining were used to confirm suspected cases of protozoa. As well as Baermann and Harada-Mori techniques and agar plate culture were implemented to diagnosis of Strongyloides stercoralis. Results: Overall, 163 subjects were examined including 126 mentally retarded individuals and 37 personnel. Ninety (55.2%) cases of participants were infected with at least one of the intestinal parasites, 69 (54.7%) of mentally retarded and 21 (56.7%) of personnel. Twenty-six mentally retarded individuals were infected with S. stercoralis (20.6%), Blastocystis hominis 30.2%, Entamoeba coli 25.4%, Giardia lamblia 5.6%, Enterobius vermicularis 1.6%, Hymenolepis nana 0.8% and Iodamoeba butschlii 1.6%. Twelve staff (32.4%) harbored B. hominis, E. coli 27%, S. stercoralis 2.7%, G. lamblia 10.8%, H. nana 2.7% and Endolimax nana 2.7%. Conclusion: High rate of intestinal parasites particularly, S. stercoralis compared to the most recent studies of general population. Therefore, regular screening and tracking the positive cases, disinfection of the living environment, training and financing of the staff, increasing the number of the workers, recruiting of professionals and trained personnel in these centers are suggested.

Abstract Background Street child is any child whose age is less than 18 years for whom the street has become his or her habitual abode and/or source of livelihood, is inadequately protected, supervised or directed by responsible adults. In Ethiopia the health problems of street children are given poor attention in research. This problem is pronounced when it comes to intestinal parasitic infections . The aim of this study was to assess the prevalence of intestinal parasitic infections and associated factors among street children in Jimma town in the year 2019. Methods and Materials: Community based cross sectional study was employed. Complete enumeration was used to include 312 street children. Pretested questionnaire was used to collect the data. Data was entered to Epidata version 3.1 and exported to SPSS version 20. Stool samples were examined by wet mount and formalin ether concentration techniques. Bivariable and multivariable logistic regression was used to identify factors associated with intestinal parasitic infection. Significance of association was decided by using the 95% confidence interval of AOR and P-value of ≤ 0.05 in the multivariable model. Result: A total of 312 children of the street were involved in the study making the response rate 96.2%. The prevalence of intestinal parasitic infection was 66.7%. Untrimmed finger nails AOR=2.03;95%CI (1.02-4.06), eating street food AOR=2.24;95% CI (1.04-5.02), practice of swimming in unprotected water bodies AOR=2.5; 95% CI (1.24-5.04), not wearing shoes at the time of data collection AOR= 3.8;95% CI (1.8-8.2) and lacking knowledge of way of transmission of intestinal parasites AOR= 2.5; 95% CI (1.25- 5.0) were significantly associated with parasitic infections. Conclusion and Recommendations: The prevalence of intestinal parasitic infections among street children in the study area was high and require integrated interventions to avert the problem. Factors like untrimmed finger nails, swimming practice, eating street foods, shoe wearing and lacking knowledge of ways of transmission of intestinal parasitic infections are associated with infection status. Measures has to be taken to curb the problem by including them in mass drug administration and targeted health education towards identified factors.

Abstract Background Previous studies reported contradicting findings about the association between intestinal parasitosis and maternal anemia. In this study we aimed to determine the prevalence of intestinal parasitic infection and its association with anemia among pregnant women in Wondo Genet district, Southern Ethiopia. Methods This facility-based cross-sectional study was conducted in June and July 2018. Pregnant women (n=352) were randomly drawn from five health centers using antenatal care follow-up lists. Trained data collectors administered the questionnaire. Capillary blood was collected and analyzed for hemoglobin using the HemoCue method. Stool sample was collected following standard procedure and analyzed for the presence and types of intestinal parasites using direct microscopy with Formalin-ether concentration technique. Association between intestinal parasitosis and anemia was measured using multivariable binary logistic regression analysis. The outputs are presented using adjusted odds ratio (AOR) with 95% confidence intervals (CI). Results The overall prevalence of intestinal parasitic infection was 38.7% (95% CI: 33.6-43.8%). One-tenth (9.7%) of the pregnant women were infected with polyparasites. Ascaris lumbricoides was the predominant infection encountered in 24.9% of the women. The other infections identified were: hookworms (11.2%), Giardia lamblia (5.4%), Entamoeba histolytica (3.4%), Trichuris trichiura (2.9%) and Schistosoma mansoni (2.3%). The mean (± standard deviation) hemoglobin concentration was 12.3 (±1.9) g/dl and 31.5% (95% CI: 26.6-36.4%) women were anemic (hemoglobin < 11 g/dl). The prevalence of anemia among women infected with intestinal parasite (55.6%) was substantially higher than the prevalence in their counterparts (16.4%) (p<0.001). In a multivariable model adjusted for multiple potential confounders including socio-economic status indicators, the odds of anemia were six times increased (AOR=6.14, 95% CI: 2.04-18.45) among those affected by at least one intestinal parasite. Conclusion Strengthening the existing water, sanitation and hygiene programs and routine deworming of pregnant mothers may help to reduce the burden of both intestinal parasitic infection and anemia in pregnant women.
