Echinococcosis is a zoonotic parasitic disease caused by the larvae of Echinococcus granulosus and E. multiltilocularis , which mainly violate the liver. And the surgical treatment is an important method to cure the disease at present. However, there are many surgical methods for the treatment of hepatic echinococcosis, and different surgeries with different indications and risks. With the standard of precision surgery and no tumor surgery, the surgical operation is more precise. The innovation of surgical methods makes the operation of curing complex hepatic echinococcosis become true...

We aim to investigate some of the pathogenetic mediators of the human echinococcosis and to obtain updated epidemiological findings on cases of echinococcosis in Calabria, Southern Italy. Echinococcosis diagnosis was based on imaging, serological investigations, and molecular assay. Indeed, real-time PCR indicated the presence of G2/G3 genotypes of Echinococcus granulosus complex. Regarding pathogenesis, a relevant novel tool of immune depression should be deemed the reduced level of serum MCP-1. Also, we found a previously unreported VEGF, possibly associated with neovascularization requested by the parasite cyst metabolism...

The faeces of the red fox, Vulpes vulpes (Linnaeus), and the domestic cat, Felis catus (Linnaeus), can be responsible for spreading eggs of Echinococcus multilocularis Leuckart, 1863 and oocysts of Toxoplasma gondii (Nicolle et Manceaux, 1908) into the environment. The accidental ingestion of these eggs or oocysts, through consumption of raw fruits or vegetables grown in or in contact with contaminated soil, can lead to alveolar echinococcosis (AE) or toxoplasmosis in humans. The present study provides a quantitative assessment of the faecal deposition by foxes and cats in kitchen gardens where fruits and vegetables are grown and its consequences for zoonosis transmission...

BACKGROUND: Cervids used to be considered the only animal intermediate hosts of the G10 genotype of Echinococcus canadensis. Yaks are often herded in the Qinghai-Tibet Plateau, China, where echinococcosis remains prevalent. However, no E. canadensis G10 cases have been recorded in yaks until now. The aim of our study was to identify causative agents of echinococcosis in yaks in this region. METHODS: Total genomic DNA was extracted from the germinal layer of one hydatid using a Blood and Tissue Kit...

Granulomas are responses to persistent nonliving bodies or pathogens, centrally featuring specialized macrophage forms called epithelioid and multinucleated giant cells. The larval stages of the cestode parasites of the taeniidae family (Taenia, Echinococcus) develop for years in fixed tissue sites in mammals. In consequence, they are targets of granulomatous responses. The information on tissue responses to larval taeniids is fragmented among host and parasite species, and scattered over many decades. We attempt to draw an integrated picture of these responses in solid tissues...

Echinococcosis is a severe zoonosis parasitic disease and mainly caused by the larvae of Echinococcus granulosus and E. multilocularis . Because of the limitation of operation level, such as recurrence and death, the drug treatment is still the most important method in our country. Meanwhile, the annual number of drug treatments is far greater than surgical treatments. Drugs play a significant role in the preoperative reduction of lesions, reducing pain, extending the life of patients .This article reviews the status of animals treatment and clinical treatment of echinococcosis treated by the benzimidazole drugs and their new formulations, provides the basis for exploring the development direction of anti-echinococcosis drug treatment research...

The Qinghai-Tibet Plateau is known as one of the highest endemic areas of echinococcosis. However, the dog infection rates of Echinococcus granulosus in the plateau regions were similar to other non-Tibetan areas with the high endemic, and most of the rates were below 40%. The infected dogs with E. multilocularis were ubiquitous in Ganzi Prefecture of Sichuan Province and Qinghai Province where many survey data were done and available, which was much different from those in non-Ti-betan areas where the geographical distribution of dogs infected with E...

INTRODUCTION: Cystic echinococcosis is a neglected zoonotic disease with worldwide distribution, which occurs mainly in pastoral regions. Echinococcus granulosus sensu stricto, is the main agent of human infection. Although Iran is an endemic area for CE in the Middle East, lack of data regarding the disease among rural inhabitants of Khuzestan province in recent years, persuaded us to perform the current study. METHODOLOGY: This cross-sectional study was conducted in 2016 using simple random sampling method in 15 villages of Shushtar county, southwestern Iran...

Echinococcus granulosus is a helminth from the family Taeniidae, which causes cystic echinococcosis (CE) in humans and diverse livestock around the world. The identification of existing genotypes in different regions is a major step towards the prevention and establishment of control programmes for the disease. This study aimed to detect CE genotypes using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) of the internal transcribed spacer-1 (ITS1) gene and sequencing of the cytochrome c oxidase subunit 1 (Cox1) gene in isolates from the central part of Mazandaran province, northern Iran...
