Trematode genus Diplostomum comprises of parasitic species which cause diplostomiasis, the 'white eye' disease in fish and heavy infection can result in mortality. The increasing availability of DNA sequences of accurately identified Diplostomum species on public data base presently enables the rapid identification of species from novel sequences. We report the first molecular evidence of the occurrence of D. pseudospathaceum in the United Kingdom. Two gene regions, nuclear internal transcribed spacer cluster (ITS1-5...

Drug resistance in helminth parasites has incurred several difficulties to livestock industry and ranked among the top public health concerns. Therefore, seeking for new agents to control parasites is an urgent strategy. In the recent years, metallic nanoparticles have been considerably evaluated for anthelmintic effects. The current research was conducted to assess possible anthelmintic impacts of zinc oxide nanoparticles (ZnO-NPs) on a prevalent gastrointestinal nematode, H. contortus. Moreover, several biomarkers of oxidative/nitrosative stress and DNA damage were measured...

During a parasitological survey of Astyanax altiparanae captured in the Mogi Guaçú river, Pirassununga, state of São Paulo, Brazil, a new species of myxozoa was observed infecting the kidney of 30 of 42 specimens. Plasmodia of the new myxozoa, referred to herein as Unicauda whippsi n. sp. were spherical and varied from 450 to 1000 μm in length. The mature spore was elongated and measured 11 ± 1.2 (10-12) μm long by 5.4 ± 0.6 (4.7-7.2) μm wide. Polar capsules of unequal length with the filament coiled 7-9 times and a unique caudal process characteristic of the genus Unicauda, were recorded...

The diagnosis of a 22 year-old male patient from Kerabari, Morang District, Nepal led to the review of human fascioliasis cases and analysis of the epidemiological situation in that country not included in the WHO fascioliasis map. Symptom onset one month before egg detection and normal levels of ALT and AST did not agree with the 3-4-month migratory period of fascioliasis. A shorter acute phase may happen when the main biliary duct is reached by the migratory juveniles directly from the intestinal lumen. The causal agent was ascribed to F...

The mechanisms responsible for the imbalance between oxidants and antioxidants in sheep infected with Haemonchus contortus are not well established. This study aimed to prove the hypothesis that oxidative stress occurring during infection by H. contortus varies according to breed, and that the parasite burden correlates with hypoalbuminaemia and anaemia. Thus, after deworming and confirming the absence of infection, two different sheep breeds, Suffolk (n = 15) and Santa Ines (n = 22), were orally inoculated with a single dose of 5,000 L3 of H...

Rhipicephalus sanguineus sensu lato (s.l.) is one of the most widespread ixodid ticks and is a competent vector of several vector-borne pathogens of veterinary and medical concern. For instance, this tick species transmits nematodes of the genus Cercopithifilaria and protozoa of the genus Hepatozoon to carnivores, including dogs. Here we investigated the occurrence of Cercopithifilaria spp. and Hepatozoon spp. in a population of ticks collected from naturally infested dogs living in rural areas of Northeastern Brazil...

Toxoplasma gondii, a coccidian parasite known to infect almost all warm-blooded animals, is the cause of one of the most common zoonotic parasitic diseases. The aim of the study is to determine whether the 529 bp fragment or the TGR1E gene is more useful target for PCR identification of T. gondii, for common use. The brains of 221 carnivores and omnivores collected between 2013 and 2015 from north-eastern Poland were examined for the presence of this parasite. The DNA was extracted and then amplified using specific primers...

Dirofilariasis is a parasitic disease of dogs and other carnivores transmitted mainly by the mosquitoes of the genera Culex, Aedes, Anopheles. Full life cycle of the Dirofilaria nematodes in humans is extremely rarely observed, usually lacking species determination at the molecular level. We report fully documented unusual clinical manifestation of subcutaneous dirofilariasis with intensive microfilariemia in peripheral blood revealed by the Knott's concentration technique. The identification of the Dirofilaria repens nematode was based on typical morphological findings for adult gravid female nematode found in the histopathological preparations...

Ascaridia (A.) galli is one of the most commonly occurring nematodes in poultry worldwide, often in hens and broiler chickens. The infection with Ascaridia galli in free-range chickens was even 70%. There is not much information about A. galli genetic features. The present study was conducted to assess the genetic diversity of A. galli isolated from hens in Poland by analyzing the nucleotide sequence of the region ITS1-5.8rRNA-ITS2 and to define its homology within the family Ascaridiidae. Adult A. galli were collected from the intestines of naturally infected hens from two flocks of free-run laying hens from the Wielkopolska region in Poland...

Fasciolosis in ruminants in India is caused by the liver fluke Fasciola gigantica. Radix (Lymnaea) spp. are known to carry the infective stages of this parasite. Understanding the seasonal prevalence of F. gigantica infection in the intermediate host is of extreme importance in order to elucidate the transmission dynamics of the parasite. So the present study was designed to determine the bioclimatic distribution of larval stages of F. gigantica in Radix spp. snails as well as to explore the genetic diversity of F...
