Housing conditions were assessed in different unowned multi-cat management models in order to evaluate their impact on the occurrence of intestinal parasites and fecal cortisol metabolite (FCM) levels. Fresh stool fecal samples were collected from rescue shelters, catteries and feline colonies for coprological analyses in order to detect intestinal parasite patency and fecal cortisol metabolites. A questionnaire provided information about the facilities, management and housing conditions of cats, including information about dog exposure, enclosure size, environment enrichment and changes to group composition. Overall, intestinal parasite infection was detected in 58.2% of fecal samples collected. The occurrence of intestinal parasites detected in free-roaming cats was 82.2%, mainly due to helminth infection. The parasite infection rate was 57.3% in rescue shelters and 34.6% in catteries. In confined cats, protozoa infection was more likely detected in rescue shelters than in catteries (RR = 2.02 (1.30–3.14), p = 0.0012). Although the FCM values were very variable between cats, the enclosure size and parasite infection were correlated with the average FCM. A small enclosure size was correlated with high fecal cortisol metabolites (p = 0.016). Protozoa-positive samples showed higher FCM levels than negative samples (p = 0.0150). High dog exposure was statistically associated with protozoa infection (p = 0.0006). The results indicated that improving housing, especially in terms of floor space and avoiding dog exposure, reduces stress and can thus be applied to make control strategies in multi-unowned-cat environments more efficient, especially when cats are confined.

This study was carried out in 1999–2000 in the northern part of Bangladesh to determine the impact of sanitary latrine use and of health education on intestinal parasites in school-aged children. The children were between 5 and 13 years of age and stool samples revealed that more than half (53%) of the study sample was still infected with one or more intestinal parasites even after 4 years of intervention. Ascariasis was found to have the highest prevalence rate (36.2%) and hookworm the lowest (10.7%). Intestinal parasite infection was significantly lower ( P<0.05) among those who used a sanitary latrine and received health education. This result is consistent with observations that the effect of sanitation and health education is slow to develop. Concerted primary healthcare activities with community development efforts should be undertaken to improve the overall living condition of the people of this area to control this problem.

Introduction: Intestinal parasites infections are endemic in Gabon. Nevertheless, they are rarely described in people living with HIV (PLHIV). Objective: The frequency of intestinal parasite infection was estimated and compared between HIV-positive and HIV un- infected individuals in Gabon; factors associated with intestinal parasites were also analysed. Material and Methods: Using a cross-sectional study design sociodemographic data, life style habits, antiretroviral therapy, cotrimoxazole use and CD4 cell count were recorded.. Stool samples from participants living in Koulamoutou and Oyem were analysed using microscopy. Chi-squared or fisher’s exact tests and logistic regression were performed. Results: Among participants (n=332), female gender was predominant (73.7%; n=135/183) and the median age was 45 [33-57] years old. Among 183 samples, 53.6% (n = 98/183) were infected by intestinal parasites. The proportion was higher (72.1%) in HIV negative participants compared to PLHIV (42.6%) (p <0.01). PLHIV were more frequently poly-infected. Infection was frequent in patients using external toilets and tap water (>70.0%). Conclusion: Prevalence of intestinal parasites is higher in seronegative participants but polyparasitism is more frequent in PLHIV. Strategies are focused on HIV negative population, but this study shows the importance of sensitization for PLHIV to improve their quality of life.

AbstractWithin-host interactions among coinfecting parasites are common and have important consequences for host health and disease dynamics. However, these within-host interactions have traditionally been studied in laboratory mouse models, which often exclude important variation and use unnatural host–parasite combinations. Conversely, the few wild studies of within-host interactions often lack knowledge of parasite exposure and infection history. Here we exposed laboratory-reared wood mice (Apodemus sylvaticus) that were derived from wild-caught animals to two naturally-occurring parasites (nematode: Heligmosomoides polygyrus, coccidia: Eimeria hungaryensis) to investigate the impact of coinfection on parasite infection dynamics, and to determine if the host immune response mediates this interaction. Coinfection led to delayed worm expulsion and prolonged egg shedding in H. polygyrus infections and lower peak E. hungaryensis oocyst burdens. By comparing antibody levels between wild and colony-housed mice, we also found that wild mice had elevated H. polygyrus-IgG1 titres even if currently uninfected with H. polygyrus. Using this unique wild-laboratory system, we demonstrate, for the first time, clear evidence for a reciprocal interaction between these intestinal parasites, and that there is a great discrepancy between antibody levels measured in the wild vs those measured under controlled laboratory conditions in relation to parasite infection and coinfection.

Opportunistic and intestinal parasite infections are common health problem among HIV/AIDS patients. Early detection and treatment of these parasites are important to improve the quality of life of this category of patients. The occurrence of intestinal parasites among 400 patients on highly active anti-retroviral drug therapy (HAART) aged 11-60 years was investigated. Standard parasitological techniques like direct microscopy, formol ether concentration and modified Ziehl- Neelsen staining techniques were used to analyze the stool samples. Intestinal parasite infections were positive in 116 (29%) of the subjects on HAART while control subjects had 12 (12%) and the difference was statistically significant (P&lt;0.05). Subjects in the age group 21-30 years had the highest infection rate 54 (35.1%). There was no statistically significant difference in infection according to age (P&gt;0.05). Females 76 (32.5%) had a higher prevalence rate than males 40 (24.1%). But there was no statistically significant difference in infection according to gender (P&lt;0.05). Patients with CD4 count of less than 200 cells/mm3 were observed to be more infected than those with CD4 count of more than 200 cells/mm3. There was a strong positive correlation (r=0.94) between CD4 count and the occurrence of intestinal parasite infection. Protozoan parasites 84 (21.0%) accounted for a higher prevalence rate than helminthic parasites 32 (8.0%). These findings has revealed a high prevalence of intestinal parasite infection among patients on HAART thus the routine screening of stool samples from these category of patients for intestinal parasites is advocated for effective management of the disease.

Aim: To assess the prevalence of intestinal parasite infections among patients who visit the Ho Teaching Hospital for stool examination from 2012 to 2016. Study Design: Retrospective study. Place and Duration of Study: Ho Teaching Hospital, August 2017 to January 2018. Methodology: The hospital’s laboratory records were reviewed. Patients’ data were recorded using a well-designed data collection tool. Data was analyzed with Statistical Package for Social Science (SPSS) version 20.0. Results:  A total of 7045 patients visited the Ho Teaching Hospital laboratory for routine stool examination within the five-year period. From the 7045 patients, 703 of them were infected with at least one of the intestinal parasites. The overall prevalence of intestinal parasite infection for the five-year period was 10.0%. Intestinal flagellates (90.0%) were the most predominant intestinal parasites, and Entamoeba histolytica recorded 5.7%. Hookworm (0.9%) was the most prevailing soil-transmitted helminth. Ascaris lumbricoides (0.1%) and Schistosoma mansoni (0.1%) were the least recorded parasites. Highest infection was among patients within age group 20 to 29 years. However, age groups below 10 years recorded low infection. This study showed that age was a risk factor for acquiring intestinal parasite infection (P≤0.001). Conclusion: Intestinal parasitic infections were recorded among patients who visited the Ho Teaching Hospital. However, most of the patients were infected with intestinal flagellates. Various stakeholders should provide advance techniques in laboratory investigation of stool samples to enhance accurate diagnosis. Sensitization of the public about the dangers of intestinal parasites should also be undertaken by the stakeholders.

Abstract Background The multifaceted interactions between gastrointestinal (GI) helminth parasites, vertebrate host gut microbiota and the immune system are emerging as a key area of research within the field of host-parasite relationships. In spite of the plethora of data available on the impact that GI helminths exert on the composition of the gut microflora, whether alterations of microbial profiles are caused by direct parasite-bacteria interactions or, indirectly, by alterations of the GI environment (e.g. mucosal immunity), remains to be determined. Furthermore, no data is thus far available on the downstream roles that qualitative and quantitative changes in gut microbial composition play in the overall pathophysiology of parasite infection and disease. Results In this study, we investigated the fluctuations in microbiota composition and local immune microenvironment of sheep vaccinated against, and experimentally infected with, the ‘brown stomach worm’ Teladorsagia circumcincta, a parasite of worldwide socio-economic significance. We compared gut microbial profiles with those obtained from groups of unvaccinated/infected and unvaccinated/uninfected animals. We show that alterations to the gut microbial composition are associated mainly with parasite infection, and that this involves the expansion of populations of bacteria with known pro-inflammatory roles that may contribute to the immunopathology of helminth disease. Using novel quantitative approaches for the analysis of confocal microscopy-derived images we also show that gastric tissue infiltration of T cells is driven by parasitic infection rather than anti-helminth vaccination. Conclusions Teladorsagia circumcincta infection leads to an expansion of potentially pro-inflammatory gut microbial species and abomasal T cells. This data paves the way for future experiments aimed at determining the contribution of the gut flora to the pathophysiology of parasitic disease, with the ultimate aim to design and develop novel treatment/control strategies focused on preventing and/or restricting bacterial-mediated inflammation upon infection by gastrointestinal helminths.

The present study evaluated the frequency of intestinal parasitoses in children in public day care centers applying parasitological and immunological diagnostic methods. Fecal samples from 121 children from six public daycare centers were analyzed using parasitological techniques. Epidemiological data were obtained through a questionnaire, where parents and / or guardians were asked, for instance, whether the children had contact with soil, ate raw food, such as vegetables or raw or undercooked meat, normally walked around barefoot or had contact with animals. Fecal samples from 82 children were also tested for Giardia intestinalis and Cryptosporidium sp. coproantigen using the enzyme-linked immunosorbent assay (ELISA) which was also used for Entamoeba coproantigen detection only in samples that tested positive for the parasite by parasitological stool exam/optical microscopy. Intestinal parasite infection was noted in 23.1% (28/121) of the children. The most frequent parasite was Giardia intestinalis (13.2%), followed by Entamoeba coli (5.8%), Blastocystis spp. (1.7%), Endolimax nana (1.7%), Enterobius vermicularis (1.7%), Cystoisospora belli (0.8%),Entamoeba histolytica/E. dispar complex (0.8%), and Ascaris lumbricoides (0.8%). Positivity for parasite infection using parasitological stool exams was significantly associated with age groups, with a higher frequency in 4 to 6 year old children (p=0.03). No association or significant variations were noted in the prevalence of intestinal parasites in relation to the epidemiological variables studied. All samples were negative for Cryptosporidium sp. and Entamoeba histolytica detected by immunological testing, and 17.1% (14/82) children tested positive for Giardia intestinalis, although using parasitological exam/optical microscopy, only 14.6% (12/82) tested positive. The high incidence of intestinal parasites, especially protozoans, suggests probable interpersonal transmission among the children, environmental contamination, or even contaminated food/water intake. Thus, consolidation of preventive measures and efficient diagnostic resources as well as control of intestinal parasites and patient treatment are of utmost importance.

Abstract Introduction While microscopic stool ova and parasite examination (MSOP) is the traditional testing method for intestinal parasites, it has low diagnostic yield when used inappropriately. To promote stewardship at our institution, MSOP was only orderable utilizing paper requisitions. The only stool parasite testing orderable in our electronic ordering system was the Giardia / Cryptosporidium immunoassay (available as stool O&P screen), which has adequate sensitivity to detect the most common regional intestinal parasites. This was changed during two regional cyclosporiasis outbreaks, when MSOP was added to our electronic ordering system (EOS) to facilitate Cyclospora detection (available as stool O&P examination). The stool O&P screen was also changed to Giardia and Cryptosporidium antigen to better reflect the testing performed. We aimed to measure the impact of this change in terms of test utilization. Methods We quantitated the amount of testing performed pre- and post-intervention over 12-month periods, outside of the outbreak period. We performed chart reviews of 141 patients who received stool parasite testing (Giardia/Cryptosporidium immunoassay and/or MSOP) and compared the proportion of appropriate vs. inappropriate stool parasite testing before (n = 73) and after (n = 68) MSOP was added to the EOS. We used the following criteria to define appropriate MSOP testing; the presence of (1) any travel history outside the continental US, (2) immunocompromised status or (3) intestinal parasite mentioned as a differential diagnosis in medical record. MSOP was considered overordered in patients who failed to fulfill criteria. Testing was deemed underordered if only Giardia/Cryptosporidium immunoassay was ordered on patients who fulfilled criteria for MSOP. Both underordering and overordering were considered inappropriate testing. Statistically significant differences were calculated using Fisher’s exact test (p&lt;0.05). Results The number of patients tested per month by MSOP increased from an average of 10 pre-intervention to 56 post-intervention (p&lt;0.0001). The proportion of appropriate MSOP utilization increased from 44% to 58% of (p=0.13). Inappropriate testing happened in both periods, though underordering was significantly higher pre-intervention (89% vs. 10% of inappropriate testing, p&lt;0.0001), while overordering was significantly higher post intervention (90% vs. 11% of inappropriate testing, p&lt;0.0001). Pre-intervention, 34 of 38 patients in whom underordering occurred were immunocompromised patients tested by the Giardia/Cryptosporidium immunoassay only. Notably, all patients who had intestinal parasite mentioned as a differential diagnosis in the electronic medical record were tested by MSOP, regardless of its availability in the ordering system. Conclusion These findings suggest that omission of MSOP from the electronic ordering system can prevent appropriate testing, particularly in immunocompromised patients. Transitioning to an electronic ordering format can promote overall test utilization and decrease the amount of inappropriately narrow testing, though this also promotes inappropriately broad testing which may represent an opportunity for future clinical decision support interventions.

BACKGROUND: The prevalence of intestinal parasitic infection still high in Indonesia and lead to nutritional disorder, especially in the school-aged children. AIM: This research conducted to find the association of intestinal parasitic infection to the nutritional status of the children. METHODS: This was a cross sectional study, conducted in January 2016 in one primary school in South Jakarta, Jakarta, Indonesia, by collecting the children’s stool from 1st to 5th grade. Direct examination of the stool was conducted in the Parasitology Department, Faculty of Medicine, Universitas Indonesia, by Lugol and eosin staining. Nutritional status categorized using BMI chart. Data were analyzed using Chi-square test, Statistical Product, and Service Solutions version 20. RESULTS: From the total 157 stool examined in the laboratory, there were 60 (38.2%) children positively infected with various kinds of intestinal parasites. Mostly the infection is caused by Blastocystis hominis, which infects 44 children (69.4%). The other infection is caused by Giardia lamblia (15.3%), Trichuris trichiura (1.4%), and hookworm (1.4%), and mixed infection of B. hominis and Escherichia coli (4.2%) and B. hominis with G. lamblia (4.2%). From the total of infected children, 17 children (28.3%) have BMI below 5th percentile, and it was considered as malnourished. Moreover, 67 uninfected children have normal nutritional status. Statistically, there is an association between intestinal parasitic infection and nutritional status in school-aged children in South Jakarta (P < 0.05). CONCLUSION: The incidence of intestinal parasitic infection in school-aged children is 38.2%. Moreover, 28.3% of the infected children were malnourished and it is suggested that children with intestinal parasite infection have low nutritional status.

Background Intestinal parasitosis is a common disease that causes misery and disability in poor populations. The number of individuals affected is staggering. From two billion peoples who harbor parasites worldwide, 300 million suffer severe morbidity and more than 25% of pregnant women are infected with hookworm, which causes intestinal bleeding and blood loss, and has been most commonly associated with anemia. Intestinal parasite infection during pregnancy has been associated with iron deficiency, maternal anemia, and impaired nutritional status, as well as decreased infant birth weight. Objective This study aimed to assess the effects of intestinal parasite infection on hematological profiles of pregnant women attending antenatal care in Debre Markos Referral Hospital from December 2017 to February 2019. Method A prospective cohort study design was conducted among 94 intestinal parasite-infected pregnant women as an exposed group and 187 pregnant women free from intestinal parasite were used as a control group. The effect of intestinal parasites on hematological profiles of pregnant women was assessed at Debre Markos Referral Hospital antenatal care ward. Socio-demographic data and nutrition status were assessed by using structured questionnaires and mid-upper arm circumference (MUAC), respectively. Two ml of venous blood and 2 gm of stool samples were collected to analyze the hematological profiles and detect intestinal parasites, respectively. Wet mount and formol-ether concentration (FEC) techniques were used to detect intestinal parasites. Hematological profile was analyzed using Mind ray BC-3000 plus instrument. Data were double entered into EpiData version 3.1 software and exported to SPSS version 24 software for analysis. Results were presented using tables and graphs. Associations of hemoglobin levels with intestinal parasitic infections were determined using binary logistic regression models. P≤0.05 was considered statistically significant. The mean hematological profile difference between parasite-infected and parasite-free pregnant women was computed using independent t-test. Results In the present study, the predominant parasites identified were Entamoeba histolytica, hookworm, Giardia lamblia, Schistosoma mansoni, and Ascaris lumbricoides. About 8.2% of intestinal parasite-infected pregnant women had mild anemia while 4% had moderate anemia. Only 1.2% of intestinal parasite-free pregnant women developed moderate anemia. The mean HGB, HCT, MCV, MCH, and MCHC values of intestinal parasite-infected pregnant women were 12.8g/dl, 38.2%, 94.7fl, 33.1pg and 34.7g/dl, respectively. But the mean HGB, HCT, MCV, MCH and MCHC values of pregnant women who were free from intestinal parasites were 14.4 g/dl, 39.8%, 94.9fl, 33.9pg and 35.5g/dl, respectively. Anemia was strongly associated with hookworm (AOR = 21.29, 95%CI: 8.28–54.75, P<0.001), S.mansoni (AOR = 63.73, 95% CI: 19.15–212, P<0.001) and A.lumbricoide (AOR = 14.12, 95% CI 3.28–60.65, P<0.001). Conclusion Intestinal parasitic infection in pregnant women caused adverse impact on hematological profiles and was an independent predictor of anemia. Intestinal parasitic infection significantly decreased pregnant the level of HGB, HCT, MCV, MCH, and MCHC values. To minimize maternal anemia deworming could be good before pregnancy.
