Abstract
Introduction Toxoplasmosis is a life-threatening disease in pregnant women, having social and economic impacts due to congenital toxoplasmosis. However, in Ethiopia, it is neglected zoonotic disease, which requires screening and identifying risk factors in pregnant women to plan a public health intervention. Methods This institutional-based cross-sectional study was employed from March to April 2019 to estimate the seropositivity and assess potential risk factors for T. gondii among pregnant women attending antenatal care in four public hospitals in Northwest Ethiopia. Four hundred and one pregnant women were recruited to collect serum samples. Toxoplasma gondii antibodies were tested using Toxo-Latex slide agglutination test. Results Thus, the overall seropositivity for T. gondii was found 70.8% (95% CI: 66.3–75.5). Multivariable logistic regression analysis showed that the average monthly income, occupational status, habits of handwashing practices after handling raw meat, water sources for drinking and agroclimatic situations revealed significant (p < 0.05) effects on seropositivity for T. gondii in pregnant women. Conclusion This survey showed high seropositivity for T. gondii among pregnant women in Northwest Ethiopia. Therefore, further studies on bioassay, isolation and genotype of the pathogen are crucial. It also requires action to prevent and control the infection with T. gondii in pregnant women, which poses a potential threat to a foetus.

Potential risk factors associated with seropositivity for Toxoplasma gondii among pregnant women and HIV infected individuals in Ethiopia: A systematic review and meta-analysis. PLoS Negl Trop Dis 2020; 14:e0008944. [PMID: 33320848 PMCID: PMC7771857 DOI: 10.1371/journal.pntd.0008944] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2020] [Revised: 12/29/2020] [Accepted: 11/03/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Toxoplasma gondii is an obligate intracellular and neurotropic apicomplexan protozoan parasite infecting almost all warm-blooded vertebrates including humans. To date in Ethiopia, no systematic study has been investigated on the overall effects of potential risk factors associated with seropositivity for Toxoplasma gondii among pregnant women and HIV infected individuals. We intended to determine the potential risk factors (PRFs) associated with seropositivity for Toxoplasma gondii from published data among pregnant women and HIV infected individuals of Ethiopia. METHODOLOGY An systematic review of the previous reports was made. We searched PubMed, Science Direct, African Journals Online, and Google Scholar for studies with no restriction on the year of publication. All references were screened independently in duplicate and were included if they presented data on at least two risk factors. Meta-analysis using the random or fixed-effects model was made to calculate the overall effects for each exposure. RESULTS Of the 216 records identified, twenty-four reports met our eligibility criteria, with a total of 6003 individuals (4356 pregnant women and 1647 HIV infected individuals). The pooled prevalences of anti-Toxoplasma gondii antibodies were found at 72.5% (95% CI: 58.7% - 83.1%) in pregnant women and 85.7% (95% CI: 76.3% - 91.8%) in HIV infected individuals. A significant overall effect of anti-Toxoplasma gondii seropositivity among pregnant women (p < 0.05) was witnessed with age, abortion history, contact with cats, cat ownership, having knowledge about toxoplasmosis, being a housewife and having unsafe water source. Age, cat ownership, and raw meat consumption were also shown a significant effect (p < 0.05) to anti-Toxoplasma gondii seropositivity among HIV infected individuals. CONCLUSIONS This review showed gaps and drawbacks in the earlier studies that are useful to keep in mind to design accurate investigations in the future. The pooled prevalence of anti-Toxoplasma gondii antibodies was found to be higher among pregnant women and HIV infected individuals. This suggests that thousands of immunocompromised individuals (pregnant women and HIV infected patients) are at risk of toxoplasmosis due to the sociocultural and living standards of the communities of Ethiopia. Appropriate preventive measures are needed to reduce the exposure to Toxoplasma gondii infection. Further studies to investigate important risk factors are recommended to support the development of more cost-effective preventive strategies.

VETERINARY PARASITOLOGY- REGIONAL STUDIES AND REPORTS 2020; 21:100425. [PMID: 32862906 DOI: 10.1016/j.vprsr.2020.100425] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/09/2020] [Revised: 06/10/2020] [Accepted: 06/14/2020] [Indexed: 10/24/2022]
Abstract
Limited data is accessible about the seroprevalence of Toxoplasma gondii infection in backyard (free-range) chickens in Ethiopia. This cross-sectional study was carried out from November 2018 to April 2019 to estimate the seroprevalence and assess associated risk factors of T. gondii infection in backyard chickens in Northwest Ethiopia. Serum samples were collected from 384 backyard chickens. Toxoplasma gondii antibodies were assayed using Toxo-Latex slide agglutination test. Seropositivity for T. gondii antibodies was confirmed in 72.4% of 384 birds. Altitude, presence of cat and dog around the house, age, breed and water source were considered as potential risk factors (p < .05) associated with Toxoplasma seropositivity in this study. But, sex was not identified as a predictor for Toxoplasma infection even though higher seroprevalence was observed in females (73.7%) than males (69.3%). In conclusion, this study indicates a high prevalence of T. gondii infection in backyard chickens in Northwest Ethiopia. Therefore, further works on epidemiology, bioassay, isolation and genetic characterization of the pathogen are imperative. It also warrants an action to prevent and control T. gondii infection in backyard chickens that could serve as an important intermediate host and pose a potential threat for consumers.

Abstract
INTRODUCTION Neglected zoonotic diseases (NZDs) have a significant impact on the livelihoods of the world's poorest populations, which often lack access to basic services. Water, sanitation and hygiene (WASH) programmes are included among the key strategies for achieving the World Health Organization's 2020 Roadmap for Implementation for control of Neglected Tropical Diseases (NTDs). There exists a lack of knowledge regarding the effect of animals on the effectiveness of WASH measures. OBJECTIVES This review looked to identify how animal presence in the household influences the effectiveness of water, hygiene and sanitation measures for zoonotic disease control in low and middle income countries; to identify gaps of knowledge regarding this topic based on the amount and type of studies looking at this particular interaction. METHODS Studies from three databases (Medline, Web of Science and Global Health) were screened through various stages. Selected articles were required to show burden of one or more zoonotic diseases, an animal component and a WASH component. Selected articles were analysed. A narrative synthesis was chosen for the review. RESULTS Only two studies out of 7588 met the inclusion criteria. The studies exemplified how direct or indirect contact between animals and humans within the household can influence the effectiveness of WASH interventions. The analysis also shows the challenges faced by the scientific community to isolate and depict this particular interaction. CONCLUSION The dearth of studies examining animal-WASH interactions is explained by the difficulties associated with studying environmental interventions and the lack of collaboration between the WASH and Veterinary Public Health research communities. Further tailored research under a holistic One Health approach will be required in order to meet the goals set in the NTDs Roadmap and the 2030 Agenda for Sustainable Development.

Abstract
OBJECTIVES To determine the seroprevalence and associated risk factors of T.gondii infection in pregnant women attending antenatal care at Bonga Hospital, Southwestern Ethiopia. METHODS A cross-sectional study was carried out from February to May 2016. Systematic sampling technique was used to collect sera from 210 pregnant women. Sample was tested for anti-T.gondii- antibodies by Latex Agglutination Test (LAT). Risk factors associated with T.gondii infection in pregnant women was assessed through structured questionnaire. Univariate and multivariate logistic regression analysis was used to check association of T.gondii infection with different risk factors using SPSS version 20. RESULTS The overall seroprevalence of T.gondii infection in pregnant women was 75.7% (95% CI: 69.9-81.5). Multivariate logistic regression analysis indicated that the odds of T.gondii infection was higher in pregnant women between age range of 36-44 (AOR=2.82; 95% CI:1.2-7.82; P=0.031), in multigravidae (AOR=3.3; 95% CI:1.36-8.04; P=0.009), in those eating raw meat (AOR=5.1; 95% CI:2.22-11.68; P=0.000), in those eating raw vegetables (AOR=5.5; 95% CI:1.03-29.5; P=0.046), in those who have history of abortion (AOR=4.4;95% CI:1.10-17.49; P=0.036), in women who drink river/streams water (AOR=5; 95% CI: 1.67-15.44; P=0.004) and in those who didn't handle raw meat (AOR=2.4; 95% CI: 1-5.56; P=0.049). CONCLUSION The present result shows high seroprevalence of T.gondii infection in pregnant women. Public education on identified risk factors and screening of pregnant women during their antenatal care should be recommended.
