Evaluation of cross-reactivity to Taenia hydatigena and Echinococcus granulosus in the enzyme-linked immunoelectrotransfer blot assay for the diagnosis of porcine cysticercosis

Taenia solium is an important zoonotic parasite that infects humans as definitive host (taeniasis) and pigs as intermediate host (cysticercosis). Serological diagnosis of porcine cysticercosis is limited to antig...

We report a case of T. multiceps infection in a yak confirmed by clinical symptoms, morphological characteristics, and molecular and phylogenetic analyses. The coenurus was thin-walled, whitish, and spherical in shape with a diameter of 10 cm. The parasite species was identified as T. multiceps by PCR amplification and sequencing of the 18S rRNA, cox1 and nad1 genes. Three gene sequences all showed high homology (all above 97%) with the reference sequences from different hosts. Moreover, phylogenetic reconstructions with the 3 published Taenia gene sequences confirmed that the Qinghai yak isolate was closely related to T. ...

Conclusions: We confirmed the presence of A. cantonensis in several provinces, which ratifies the endemic nature of this zoonosis in the national territory. Rattus spp. specimens constitute the definitive hosts of the parasite, which together with the presence of intermediate hosts, indicates the zoonotic potential of this parasitic infection.

Authors: Patiño JA, Olivera MJ Abstract Anisakiasis is a zoonotic parasitic disease caused by consumption of raw or undercooked fish or seafood infected with nematodes of the Anisakis, Pseudoterranova or Contracaecum genera. Here, we describe the first case of anisakiasis in Colombia and summarize the available literature. A 52-year-old female with a history of abrupt-onset sharp epigastric pain, nausea, vomit, diarrhea, and urticaria following fish consumption consulted the health service. The physical examination revealed moderate tenderness of the epigastric region; the laboratory evaluation showed leukoc...

Abstract In 2005, the network decided to increase its number of target diseases to include other helminthic zoonoses such as fascioliasis, clonorchiasis, opisthorchiasis, paragonimiasis and cysticercosis and in the process expanding membership to include South Korea, Vietnam, Thailand and Japan. NTDs were eventually included as awareness is heightened on these diseases affecting poor and developing countries. Researches on clonorchiasis and opisthorchiasis unravel the mechanism by which these diseases eventually predispose to cholangiocarcinoma. The liver cancer associated with these liver fluke infections necessi...

Parasites with neuroinvasive stages, such as Toxoplasma gondii or Toxocara canis, can cause detrimental damage in the brain of intermediate or paratenic hosts. Therefore,...

Valente, Carlos Fonseca, Luís Madeira de Carvalho, Rita Tinoco TorresAbstractAs a top predator, the Iberian wolf (Canis lupus signatus) plays a major role shaping interactions within food webs. Due to its conservation status in Portugal, i.e. endangered, it is important to understand the role of parasites in this population, since they can be a limiting factor for the population fitness and trophic interactions and, ultimately, their survival. From November 2017 to August 2018, 33 fre...

Publication date: Available online 12 September 2019Source: Parasitology InternationalAuthor(s): Alexa Seal, Catherine Harding, Shokoofeh ShamsiAbstractDespite the increasing popularity of seafood in Australia and various reports of infection with transmissible parasites in Australian edible aquatic animals such as fish, the number of reported cases of human infections in the country is low. This raised the question that Australian medical doctors may not be fully aware of the presence of these parasites in Australia, which in turn can lead to misdiagnosis of infections. This also may lead to an underestimation of the risk...

Conclusion: Based on the results, this step-by-step immunoinformatics approach could be considered as a rational platform for designing vaccines against such multi-stage parasites. Furthermore, it is proposed that this multi-epitope vaccine is served as a promising preventive anti-echinococcosis agent. PMID: 31508329 [PubMed]
