Schistosomiasis seriously affects human health in tropical regions. Its prevention is more important than treatment, raising the need for effective control methods. Recently, the role of nanomaterials in medical science has been growing. The present study aimed to evaluate the potential effects of silver (Ag) and gold (Au) nanoparticles (NPs) on Biomphalaria alexandrina snails and Schistosoma mansoni cercariae in vitro and to assess their effects on the infectivity of cercariae in vivo. The in vitro study proved that Ag and Au NPs were effective in killing B...

The study of parasites typically crosses into other research disciplines and spans across diverse scales, from molecular- to populational-levels, notwithstanding promoting an understanding of parasites set within evolutionary time. Today, the 2030 Sustainable Development Goals (SDGs) help frame much of contemporary parasitological research, since parasites can be found in all ecosystems, blighting human, animal and plant health. In recognition of the multi-disciplinary nature of parasitological research, the 2017 Autumn Symposium of the British Society for Parasitology was held in London to provide a forum for novel exchange across medical, veterinary and wildlife fields of study...

Free-living amoebae (FLA) are protozoa ubiquitously found in nature. As some species or strains of these FLA are pathogenic for humans and animals, they represent objects of medical and parasitological research worldwide. Storage of valuable FLA strains in laboratories is often time- and energy-consuming and expensive. The shipment of such strains as frozen stocks is cumbersome and challenging in terms of cooling requirements as well as of transport regulations. To overcome these difficulties and challenges in maintenance and transport, we present a new method to generate lyophilised samples of non-cyst-forming FLA (Ripella (Vannella) spp...

Background: Opportunistic Intestinal Parasites (OIPs) commonly cause morbidity in HIV/AIDS patients due to the decline of CD4+ T-cells. The burden of Opportunistic Intestinal Parasitic Infections (OIPIs) in Ethiopia is expected to be high due to poor sanitation and co-pandemicity of HIV/AIDs. Therefore, frequent assessment of the magnitude and associated factors for intestinal parasitosis is essential for the management of HIV/AIDS patients. Methods: A hospital based cross-sectional study was conducted among patients attending Arba Minch Hospital Antiretroviral Therapy (ART) Clinic from March to June 2016...

Fascioliasis is a foodborne zoonotic disease caused by the two parasite species Fasciola hepatica and F. gigantica . In spite of the presence of both species of Fasciola in the livestock, to our knowledge, to date, no cases of human F. gigantica infection have been reported in Iran officially. Here, we report such a case in a 25 yr old woman referred to The Department of Medical Parasitology and Mycology, School of Public Health, Tehran University of Medical Sciences, Tehran, Iran in 2016. CT imaging and MRCP revealed an ill-defined lesion of segments of liver...

BACKGROUND: Exotic reptiles such as tortoises, have become increasingly common domestic pets worldwide and are known to host different gastrointestinal parasites. Some of these parasites bear zoonotic potential. In the present survey, we parasitologically examined tortoise faecal samples (n = 1005) from 19 different species held as pets in private German households and German zoological gardens. METHODS: Saline faecal smears were used to generate prevalence data for potentially health-compromising gastrointestinal parasites...

Beginning in 1963, the founding rationale of Advances in Parasitology was to provide authentic, well-documented reviews by leading experts, about the progress being made in their area of specialism to inform the wider cadre of parasitologists, disseminating this information across allied disciplines and all users. Some 55 years later, the Series has accumulated over 667 published articles, with just over 650 authors contributing either alone or in collaboration, and has successfully served the parasitological needs of medical, veterinary and wildlife scientific communities with equity, notwithstanding treatises on vectors or intermediate hosts, as well as 'honorary parasites' such as viruses, bacteria and fungi...

Fleas have great medical relevance as vectors of the causative agents of several diseases in animals and humans and rodents are the principal reservoirs for these pathogens. Argentinian Patagonia has the highest diversity of rodent fleas in South America. However, parasitism rates of rodents by fleas, the factors that influence them and the ecological aspects that modulate geographical distributions of flea-host association remain unknown for this region. This is the first study to record the diversity, prevalence, abundance, geographical distributions and host ranges of fleas in Argentinian Patagonia...

BACKGROUND: The lack of effective short-course therapies for treatment of the adult stage of filarial worms is a major limitation in the global effort to eliminate lymphatic filariasis. Studies using current small mammal models of lymphatic filariasis are limited by difficulties in quantifying adult worm numbers and in assessing lymphatic anatomy and function. METHODOLOGY/PRINCIPAL FINDINGS: Here, we re-established Brugia malayi infection of ferrets as a model for lymphatic filariasis and demonstrated parasitological, immunological, and histological parallels with human infection...

In the reported case, a 41-year-old Italian man came to the clinician's observation reporting cramps, bloating and watery diarrhoea a few days after drinking water indicated as unpotable from a fountain in a farm area. The medical suspicion was directed at both gluten intolerance and enteric infection, eventually of waterborne origin. Gluten intolerance was investigated by intestinal biopsy and excluded, while stool analyses ruled out infective bacteriological or viral agents and parasites. Subsequently, a persistent eosinophilia was revealed and a parasitological analysis was again suggested, planning for a more sensitive molecular method...
