Prevalence of gastrointestinal parasites in bonnet macaque and possible consequences of their unmanaged relocations.

PLoS One 2018 15;13(11):e0207495. Epub 2018 Nov 15.

Department of Conservation Biology, Sálim Ali Centre for Ornithology and Natural History, Coimbatore, Tamil Nadu, India.

Relocation is one of the mitigating measures taken by either local people or related officers to reduce the human-bonnet macaque Macaca radiata conflict in India. The review on relocations of primates in India indicates that monkeys are unscreened for diseases or gastrointestinal parasites (henceforth endoparasites) before relocation. We collected 161 spatial samples from 20 groups of bonnet macaque across their distribution range in south India and 205 temporal samples from a group in Chiksuli in the central Western Ghats.

Przegl Epidemiol 2018 ;72(3):349-361

University of Warsaw, Faculty of Biology, Department of Parasitology

Co-infections of HIV and other pathogens constitute an important clinical and epidemiological problem. Many studies have played attention to opportunistic co-infections due to the fact that they are used as an indicator for development of AIDS and are present on the all continents. However, in HIV-infected patients helminth infections, which are not aetiologic agents of opportunistic infections, are becoming more and more important. Read More

Soil-Transmitted Helminth Infections and Anemia in Schoolchildren from Corn Island Archipelago (RAAS, Nicaragua).

Am J Trop Med Hyg 2018 Dec;99(6):1591-1597

Departamento Parasitología, Facultad Farmacia, Universidad Valencia, Burjassot, Valencia, España.

The prevalence and intensity of soil-transmitted helminth (STH) infections in schoolchildren from Corn Islands (Nicaragua) were examined to detect mono- or poly-STH infected children, measuring different intensity levels, and to elucidate measurably increased odds of being anemic. A total of 341 stool samples provided by 2- to 15-year-old children were examined using a concentration technique and a Kato-Katz slide. Intensity of infection was expressed as eggs per gram (epg) of feces to classify light, moderate, or heavy intensity infection. Read More

Ascariasis as a model to study the helminth/allergy relationships.

Parasite Immunol 2018 Oct 8:e12595. Epub 2018 Oct 8.

Institute for Immunological Research, University of Cartagena, Cartagena, Colombia.

Ascariasis is the most frequent soil transmitted helminthiasis and, as well as other helminth infections, is expected to influence the clinical presentation of allergic diseases such as asthma. Indeed, several clinical and experimental works have shown an important impact either increasing or suppressing symptoms, and the same effects have been detected on the underlying immune responses. In this review we analyze the work on this field performed in Colombia, a Latin American tropical country, including aspects such as the molecular genetics of the IgE response to Ascaris; the allergenic activity of Ascaris IgE-binding molecular components and the immunological and clinical influences of ascariasis on asthma.

Defining stopping criteria for ending randomized clinical trials that investigate the interruption of transmission of soil-transmitted helminths employing mass drug administration.

PLoS Negl Trop Dis 2018 Oct 1;12(10):e0006864. Epub 2018 Oct 1.

The DeWorm3 Project, The Natural History Museum of London, London, United Kingdom.

The current World Health Organization strategy to address soil-transmitted helminth (STH) infections in children is based on morbidity control through routine deworming of school and pre-school aged children. However, given that transmission continues to occur as a result of persistent reservoirs of infection in untreated individuals (including adults) and in the environment, in many settings such a strategy will need to be continued for very extended periods of time, or until social, economic and environmental conditions result in interruption of transmission. As a result, there is currently much discussion surrounding the possibility of accelerating the interruption of transmission using alternative strategies of mass drug administration (MDA). Read More

Soil-transmitted helminth parasites and allergy: Observations from Ecuador.

Parasite Immunol 2018 Sep 19:e12590. Epub 2018 Sep 19.

There is considerable interest as to potential protective effects of soil-transmitted helminths (STH) against allergy and allergic diseases. Here, we discuss findings of studies done of the effects of STH parasites on atopy and allergic diseases in Ecuador. While cross-sectional studies have consistently shown a reduced prevalence of allergen skin prick test (SPT) reactivity among infected schoolchildren, the removal of these infections by repeated deworming did not affect SPT prevalence over the short-term (ie, 12 months) but may have increased SPT prevalence over the long-term (ie, 15-17 years).

Indian J Med Res 2018 06;147(6):533-544

Soil-transmitted helminth (STH) infections continue to be a major global cause of morbidity, with a large proportion of the burden of STH infections occurring in India. In addition to direct health impacts of these infections, including anaemia and nutritional deficiencies in children, these infections also significantly impact economic development, as a result of delays in early childhood cognitive development and future income earning potential. The current World Health Organization strategy for STH is focused on morbidity control through the application of mass drug administration to all pre-school-aged and school-aged children. Read More

Developing a real-time PCR assay based on multiplex high-resolution melt-curve analysis: a pilot study in detection and discrimination of soil-transmitted helminth and schistosome species.

Parasitology 2018 Nov 28;145(13):1733-1738. Epub 2018 Aug 28.

Department of Parasitology,Liverpool School of Tropical Medicine,Liverpool, L3 5QA,UK.

With the push towards control and elimination of soil-transmitted helminthiasis and schistosomiasis in low- and middle-income countries, there is a need to develop alternative diagnostic assays that complement the current in-country resources, preferably at a lower cost. Here, we describe a novel high-resolution melt (HRM) curve assay with six PCR primer pairs, designed to sub-regions of the nuclear ribosomal locus. Used within a single reaction and dye detection channel, they are able to discriminate Ancylostoma duodenale, Necator americanus, Strongyloides stercoralis, Ascaris lumbricoides, Trichuris trichiuria and Schistosoma spp. Read More
