The discovery of a Hematodinium-like dinoflagellate infecting Nephrops norvegicus has led to a pathological investigation into the effects on the host and the apparent progression of the disease syndrome The parasite is systemic, invading the haemocoel and the connective tissues of most organs via the haemal spaces. An increase in the combined number of parasites and haemocytes in the haemolymp...

Plasmodium falciparum genotyping has recently undergone a revolution, and genome-wide genotype datasets are now being collected for large numbers of parasite isolates. By contrast, phenotyping technologies have lagged behind, with few high throughput phenotyping platforms available. Invasion of human erythrocytes by Plasmodium falciparum is a phenotype of particular interest because of its cent...

BACKGROUND The mechanisms by which α-thalassemia and sickle cell traits confer protection from severe Plasmodium falciparum malaria are not yet fully elucidated. We hypothesized that hemoglobinopathic erythrocytes reduce the intraerythrocytic multiplication of P. falciparum, potentially delaying the development of life-threatening parasite densities until parasite clearing immunity is achieved....

this paper presents a total of 11 known crustacean parasite species from 51 host species belonging to 7 families, with 17 genera reported from cultured and wild fishes in three faunal regions of iran. among them, one belonging to branchiura order, namely argulus foliaceus, was found on capoeta capoeta in makoo reservoir as well as on cyprinus carpio, chalcalburnus sp., hypophthalmichthys molitr...

hyalomma marginatum is a hard-bodied tick found on animals. this tick has been implicated in the transmission of bahig virus, a pathogenic arbovirus previously thought to be transmitted only by mosquitoes.

Natural populations are commonly exposed to complex stress scenarios, including anthropogenic contamination and their biological enemies (e.g., parasites). The study of the pollutant-parasite interplay is especially important, given the need for adequate regulations to promote improved ecosystem protection. In this study, a host-parasite model system (Daphnia spp. and the microparasitic yeast M...

This paper describes the development of a novel microfluorimetric assay to measure the inhibition of Plasmodium falciparum based on the detection of parasitic DNA by intercalation with PicoGreen. The method was used to determine parasite inhibition profiles and 50% inhibitory concentration values of known or potential antimalarial drugs. Values for parasite inhibition with known anti-malarial d...

Herein we report that in vitro experiments with different initial parasite densities (1, 5, and 10 cysts per mL of culture medium) show that cysts at densities of 10 and 5 grow faster than those at 1, and that they release into the culture medium factors which increase the budding rates of the slower lower-density ones. Close contact among the incubated cysts also favors budding, thus suggestin...

McCONNELL, E. E., BASSON, P. A. & PIENAAR, J. G. Pneumocystosis in a domestic goat. Onderstep oort ]. vet. Res., 38 (2), 117-126 (1971). A fatal case of an infection by the parasite, Pneumocystis carinii Delanoe & Delanoe, 1914, is described in a young domestic goat. The disease was manifested as a severe diffuse interstitial pneumonitis accompanied by filling of the alveolar air spaces by larg...

Parasite location has been proposed as an important factor in the behavioural changes observed in rodents infected with the protozoan Toxoplasma gondii. During the chronic stages of infection, encysted parasites are found in the brain but it remains unclear whether the parasite has tropism for specific brain regions. Parasite tissue cysts are found in all brain areas with some, but not all, pri...
