Introduction
Hookworm infections are neglected tropical diseases of humans and animals worldwide. A meta-analysis and systematic review was designed to evaluate the prevalence of hookworm infection in animal and human hosts in Asia until July 2018.
Methods
The available online articles of five English databases (PubMed, Scopus, Science Direct, Web of Science and Google Scholar) were explored.
Results
The most parasitized carnivores were jackal (48%, CI: 4 to 91%), followed by dog (41%, CI: 29 to 53%), cat (26%, CI: 14 to 38%) and the red fox (19%, CI: 13 to 24%). The weighted prevalence of Ancylostoma braziliensis, A. caninum, A. ceylanicum, A. tubaeforme and Uncinaria stenocephala isolated from different canids were found to be 27% (CI: 21 to 33%), 23% (CI: 7.0 to 53%), 24% (CI: 12 to 35%), 44% (CI: 37 to 51%) and 37% (CI: 18 to 55%), respectively. In total, 98 records were obtained for human hookworms from 3209 760 examined individuals and the calculated weighted prevalence in this population was 19% (CI: 17 to 20%).
Conclusions
These findings highlight a desirable ecological milieu for parasite survival and transmission in such territories, which implicates revisiting control programs and public health infrastructures in those areas.
Aim
In spite of the importance of toxoplasmosis and toxocariasis among the high‐risk groups, such as pregnant women, the infections are categorized as a neglected tropical disease by the World Health Organization. Toxoplasma gondii and Toxocara spp. infections can cause systemic and ocular diseases in infants during pregnancy. In this study, we investigated seroprevalence and risk factors of toxoplasmosis, toxocariasis and their co‐infection in pregnant women and non‐pregnant women referred to the healthcare facilities of Ilam province, west of Iran.
Methods
A total of 378 sera samples (189 pregnant women and 189 non‐pregnant women) was investigated for the presence of IgG antibodies against T. gondii and Toxocara spp. by Enzyme‐linked immunosorbent assay (ELISA). The samples of all pregnant women with abortion (56 cases) were also evaluated for IgM anti‐toxoplasmosis antibody by ELISA method. Moreover, associated factors were obtained from the participant's questionnaires. Data analysis for this study was performed using the spss software version 20.
Results
Seroprevalence of T. gondii, Toxocara spp., and their co‐infection in pregnant women was 39.7%, 21.2% and 9.5%, respectively. Regarding the risk factors, the contact with a cat (P = 0.04) and dog (P = 0.00) were significantly associated with T. gondii and Toxocara spp., respectively.
Conclusion
This study highlighted the importance of serological diagnosis before pregnancy. Moreover, we believe that more epidemiological studies are needed for a better understanding of overlaps between T. gondii and Toxocara spp. in pregnant women.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
