This study is aimed at evaluating the seroprevalence and associated risk factors of Toxoplasma gondii infection in the population referred to rural and urban health care centers in Zahedan, southeast Iran. Methods A total of 1,324 blood samples of patients referred to the health care centers were evaluated using the IgG Toxoplasma ELISA Kit, between October 2019 and August 2021. The obtained data were analyzed through univariable and multivariable regression models. Results The seropositivity of Toxoplasma gondii infection was obtained at 18.8%. In the multivariable logistic regression model, risk factors including age group of 11-30 (OR = 3.25, 95% CI: 1.29-7.06), urban residency (OR = 4.36, 95% CI: 2.9-6.3), students (OR = 3.76, 95% CI: 1.88-4.53), and contact with cat (OR = 7.67, 95% CI: 4.76-12.36) were significantly associated with seropositivity to Toxoplasma gondii infection. Moreover, consumption of washed vegetables with salt or detergents decreases (OR = 0.14, 95% CI: 0.09-0.23) the risk of Toxoplasma gondii infection. According to the results of the multivariable logistic regression, no significant association was observed between seropositivity to Toxoplasma gondii and other risk factors. Conclusion The results of this study indicated significant seropositivity to Toxoplasma gondii infection in the population referred to rural and urban health care centers in Zahedan, Iran. Therefore, health programs should be considered for raising awareness regarding the risk factors for Toxoplasma gondii infection in this region.","PeriodicalId":16662,"journal":{"name":"Journal of Parasitology Research","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2022-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49496071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to investigate the occurrence of helminthes in pig production, as well as factors influencing their prevalence in Menoua, Western Highlands of Cameroon. Thus, 597 fecal samples from 100 farms of three production types (farrower, grower, and farrow-to-finish) were collected together with data on farmer and management characteristics. Samples were qualitatively and quantitatively analyzed. Eggs of eight helminthes were identified: Hyostrongylus rubidus (81.10%, 50-550 epg), Strongyloides ransomi (34.5%, 50-150 epg), Trichostrongylus sp. (28.1%, 50-650 epg), Ascaris suum (11.6%, 50-200 epg), Metastrongylus sp. (10.4%, 50-250 epg), Oesophagostomum dentatum (5.7%, 50-150 epg), Trichuris suis (4.0%, 50-150 epg), and Macracanthorhynchus hirudinaceus (0.2%, 50-50 epg). The overall prevalence was 89.3% (533 out of 597). Single infestations were 30.2%, while mixed infestations were 59.1%. A. suum, S. ransomi, and strongyles (H. rubidus, Trichostrongylus sp., Metastrongylus sp., and O. dentatum) were found in almost all age groups but the prevalence of A. suum increased with the growing age to drop in older animals. H. rubidus was found in all farm types followed by S. ransomi in farrower and farrow-to-finish farms. The other parasites were present only in farrow-to-finish farms. Coccidia parasites were also found including Isospora suis (26.30%, 50-12500 oocysts per gram of feces (opg)) and Eimeria spp. (1.40%, 100-100 opg). The risk of infestation for some parasites was lower with increasing herd size, high education level of farmers, and in wooden piggeries and semipermanent structures. The infestation risk was higher for all the investigated parasites for pigs escaping the pens. The overall significance of these parasites on growth and reproduction of the naturally infested pigs deserve assessment. Necropsy studies to confirm the worm burden are needed. Risk factors were identified, thus paving the way to design successful helminth control in pig production enterprises.","PeriodicalId":16662,"journal":{"name":"Journal of Parasitology Research","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2022-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47091547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They pose a high burden in pregnant women in developing countries causing maternal anemia, low birth weight, and prenatal mortality. This study is aimed at assessing intestinal parasite infection prevalence, species diversity, and associated factors among pregnant women. Methods A community-based cross-sectional study was conducted among pregnant women in Debre Elias district from March 2021 to July 2021. Three hundred sixty-three study participants meeting the inclusion criteria were enrolled for the study, and all submitted the required amount and quality of stool specimen. Immediately after collection, macroscopic (gross) and microscopic (saline wet mount) examination of stool sample was performed to detect and identify intestinal parasites. The generated data were checked for completeness, coded, entered, and analyzed using SPSS version 20.0 (SPSS Inc., Chicago, 2011) software. Binary logistic regression was applied to show significant association between dependent and independent variables. Statistically significant association was declared at a P value of < 0.05. Result Of the study participants screened for intestinal parasite, 43.5% (158/363) were infected with at least one intestinal parasite. From the total positives, 40.5% (147/363) were mono and 3.0% (11/363) were double infections. Five intestinal parasite species were recorded, of which hookworm was the predominant, (65.2%, 103/158) followed by E. histolytica/dispar (12.7%, 20/158) and G. lamblia (11.4%, 18/158). Ascaris lumbricoides and Taenia species comprised the least percentage (1.9%, 3/158 each). Source of drinking water and occupation were identified as significant factors associated with intestinal parasite infection. Farmer pregnant women were 6.41 times (AOR = 6.41, 95% CI: 1.05-39.16; P = 0.034) more likely to be infected by intestinal parasites than their counterparts. Pregnant women who drank tape water were 0.52 times less (AOR = 0.52, 95% CI: 0.30-0.88; P = 0.017) likely to be infected by intestinal parasites.

The problem is highly pronounced in children under five years of age who are not able to adhere to prevention and control precautions. Objective To assess the prevalence of intestinal parasitic infections (IPIs) and associated factors among diarrheic children under five years of age attending Bahir Dar and Han Health Centers, Bahir Dar, Northwest Ethiopia. Methods An institution-based cross-sectional study was conducted among diarrheic children less than five years of age at Bahir Dar and Han Health Centers, Northwest Ethiopia, 2020. A total of 221 diarrheic children less than five years of age were recruited using the convenience sampling technique. Data were collected using a pretested structured Amharic version questionnaire after obtaining informed consent from children's parents or guardians. Approximately 1 mL of fresh fecal specimen was collected and subjected to direct saline wet mount microscopy. All data were entered into Epi Info version 7 and transferred to SPSS statistical software version 20 for analysis. Logistic regression was employed to assess risk factors associated with increased prevalence of intestinal parasitic infection in diarrheic children under five years of age, and a P value < 0.05 was taken as statistically significant. Results The overall prevalence of intestinal parasites was 19% (95%CI = 14–24.6). The most prevalent intestinal parasites were Entamoeba histolytica/Entamoeba dispar (24 (10.86%)), Giardia lamblia (12 (5.43%)), and Ascaris lumbricoides (2 (0.9%)). Children's mother/guardian washed their hands sometimes after the toilet (AOR = 2.98, 95% CI: 1.09-8.18), children who always eat unwashed fruits and vegetables (AOR = 4.63, 95% CI: 1.09–19.75), and children's mother/guardian who had no knowledge about the mode of transmission (AOR = 4.03, 95% CI: 1.04–15.64) were risk factors significantly associated with increased intestinal parasitic infections.

The term “endoparasites” refers to infections caused by both helminths and protozoa. In many places in Ethiopia, particularly Debre Tabor, epidemiological data on the prevalence and associated variables of endoparasites among under-five children is unavailable. Thus, the aim of this study was to gather baseline data on the prevalence of endoparasites and their associated variables among under-five children who visited the Debre Tabor comprehensive specialized hospital in Northwest Ethiopia. A hospital-based quantitative cross-sectional study was used. The study was carried out from May 1 to November 30, 2021. Study participants were selected by a systematic sampling technique. The stool specimen was examined for the presence of different stages of intestinal parasites (adult, trophozoite, larvae, cysts, and ova) using direct wet mount, modified formal-ether sedimentation, and modified Ziehl–Neelsen methods. The IBM SPSS statistical package (version 23) was used to enter and analyze the collected data. The data was summarized using frequency tables and a bar chart. The adjusted odds ratio and p value <0.05 were used to declare the final association. In the present study, a total of 258 under-five children and their mothers/guardians were involved in the study, with a response rate of 100%. More than half of the respondents, 137 (53.10%), were females, and 159 (61.63%) were in the age group of 24 to 59 months. The overall prevalence of one or more endoparasites among under-five children was 45 (17.44%). Multivariate logistic regression analysis showed that health supervision, child food freshness, regular trimming of fingernails, and children's playground cleanliness were significantly associated with childhood endoparasites. The present study demonstrated a higher prevalence of endoparasites among under-five children.

Conversely, several studies have shown that Toxoplasma parasite can increase the level of dopamine in an infected host. This study was conducted to assess the serum, cerebral dopamine levels, and downregulation of Parkinson's disease manifestations in mice with chronic toxoplasmosis. Methods PD induction was done by oral inoculation of rotenone into BALB/c mice. To induce the chronic infection, cysts of T. gondii Prugniaud strain (genotype II) were injected intraperitoneally into the mice. The rotarod test was used for the evaluation of functional motor disorders in experimental mice. The serum and cerebral dopamine levels of the mice were also measured by using high-performance liquid chromatography (HPLC) on consecutive periods (10 days). Results Findings of the rotarod test showed the highest and lowest average of running duration belonged to the uninfected mice and PD mice, respectively. Remarkably, the running duration of infected mice with PD was higher than PD mice. As well, the level of serum and cerebral dopamine increased in mice with PD and toxoplasmosis in comparison with PD mice. Conclusion Increasing the serum and cerebral dopamine levels in mice infected with toxoplasmosis is related to the presence of the parasite. Moreover, the dopamine upregulation due to the infection is effective in the reduction of PD complications.","PeriodicalId":16662,"journal":{"name":"Journal of Parasitology Research","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2022-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46583072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
