OBJECTIVE: Bovine cysticercosis is a cattle infection caused by a tapeworm, Taenia saginata. While the condition is relatively innocuous, the parasite infects the small intestine of humans in its mature stage and causes a few specific symptoms such as abdominal pain and nausea. METHODS: Between February 2013 and February 2014, a total of 640 cattle were randomly selected from all the cattle sent to the abattoir, and some internal organs and skeletal muscles of these cattle were inspected...

Changes in seroprevalence of cysticercosis diagnosed in Chandigarh, India between 1998 and 2014 were investigated by extraction and analysis of data from records held at the Postgraduate Institute of Medical Education and Research in Chandigarh. Among the total number of samples for which cysticercosis had been suspected during this period (N = 9650), 1716 (17·8%) were seropositive. Adults were more likely to be seropositive than children, and women were more likely to be seropositive than men. In addition to there being fewer patients with suspicion of cysticercosis over the data analysis period, the proportion of patients seropositive also reduced significantly...

An estimated 50 million persons worldwide are infected with cysticerci, the larval forms of the Taenia solium tapeworm. Neurocysticercosis can cause seizures, epilepsy, and hydrocephalus, and fatal cases have been reported in the United States in immigrants and in travelers returning from endemic countries. Pregnant women with symptomatic neurocysticercosis present treatment challenges, whereas those with the adult tapeworm infection (i.e., taeniasis) can put their infants and other family members, as well as obstetrician-gynecologists and their staff, at risk for cysticercosis...

Hydatid disease is a helminth infection with various clinical complications caused by the larval stage of the dog tapeworm Echinococcus granulosus. The scolicidal agents have been broadly applied for inactivation of the fertile cysts up to now, but these scolicidal agents have several side effects on patients. Therefore, this study aimed to explore the scolicidal activity of green synthesized gold nanoparticles (AuNPs) utilizing mycelia-free culture filtrate of Penicillium aculeatum against hydatid cyst protoscolices of E...

Echinococcosis is a serious parasitic disease that ends lethally in 95% of untreated infected patients. It was first diagnosed in Slovakia in the year 2000. It is caused by the larval stage of a tapeworm belonging to the genus Echinococcus, which was assigned to the group "A" of zoonoses in the year 2004. The number of new infections is rising because of increasing percentage of infected red foxes (Vulpes vulpes). Early and accurate diagnosis of infections with this parasite is essential for proper initiation of adequate therapy...

Stable isotope analysis of commercially and ecologically important fish can improve understanding of life-history and trophic ecology. However, accurate interpretation of stable isotope values requires knowledge of tissue-specific isotopic turnover that will help to describe differences in the isotopic composition of tissues and diet. We performed a diet-switch experiment using captive-reared parasite-free Eurasian perch (Perca fluviatilis) and wild caught specimens of the same species, infected with the pike tapeworm Triaenophorus nodulosus living in host liver tissue...

Parasite infections are a product of both ecological processes affecting host-parasite encounter rates and evolutionary dynamics affecting host susceptibility. However, few studies examine natural infection variation from both ecological and evolutionary perspectives. Here, we describe the ecological and evolutionary factors generating variation in infection rates by a tapeworm (Schistocephalus solidus) in a vertebrate host, the threespine stickleback (Gasterosteus aculeatus). To explore ecological aspects of infection, we measured tapeworm prevalence in Canadian stickleback inhabiting two distinct environments: marine and freshwater...

Methods to maintain the life cycle of pathogenic organisms become powerful tools for studying molecular and cellular bases of infectious diseases. Spirometra erinaceieuropaei is a parasitic tapeworm that causes sparganosis in humans. Because S. erinaceieuropaei has a complex life cycle with different stages and host species requirements, there have been no reports to establish the complete life cycle in the laboratory. In this study, using Cyclops as the first intermediate host, mouse as the experimental second intermediate host, and dog as the final host, we succeeded in maintaining S...

Histopathological, immunofluorescence and ultrastructural studies were conducted on the intestines of four fish species infected with different taxa of enteric helminths. Brown trout (Salmo trutta trutta), eel (Anguilla anguilla) and tench (Tinca tinca) obtained from Lake Piediluco (central Italy) were examined. Brown trout and eel were infected with two species of acanthocephalans, and tench was parasitized with a tapeworm species. In addition to the above site, specimens of chub (Squalius cephalus) and brown trout infected with an acanthocephalan were examined from the River Brenta (north Italy)...

Neurocysticercosis (NCC) is a parasite infection caused by the tapeworm Taenia solium in its larvae stage which affects the central nervous system of the human body (a definite host). It results in the formation of multiple lesions in the brain at different locations during its various stages. During diagnosis of such symptomatic patients, these lesions can be better visualized using a feature based fusion of Computed Tomography (CT) and Magnetic Resonance Imaging (MRI). This paper presents a novel approach to Multimodality Medical Image Fusion (MMIF) used for the analysis of the lesions for the diagnostic purpose and post treatment review of NCC...

The Ezo red fox (Vulpes vulpes schrencki), a subspecies endemic to Hokkaido island, Japan, is a known host species for the tapeworm Echinococcus multilocularis. To develop tools for molecular ecological studies, we isolated 28 microsatellite regions from the genome of Ezo red fox, and developed 18 polymorphic microsatellite markers. These markers were characterized using 7 individuals and 22 fecal samples of the Ezo red fox. The number of alleles for these markers ranged from 1 to 7, and the observed heterozygosity, estimated on the basis of the genotypes of 7 individuals, ranged from 0...

Cystic echinococcosis (CE) is a pandemic infectious disease caused by the tapeworm Echinococcus granulosus that forms cysts in different organs such as lungs and liver. Imaging examination and serological tests have some drawbacks such as low sensitivity. In this study, we used an up-to-date workflow of laser microdissection-based microproteomics and matrix-assisted laser desorption/ionization time-of-flight imaging mass spectrometry in order to depict the proteomic pattern of CE in the liver. This investigation revealed specific markers of a parasitic cyst in liver...

Taenia solium taeniosis/cysticercosis was declared eradicable by the International Task Force for Disease Eradication in 1993, but remains a neglected zoonosis. To assist in the attempt to regionally eliminate this parasite, we developed cystiSim, an agent-based model for T. solium transmission and control. The model was developed in R and available as an R package (http://cran.r-project.org/package=cystiSim). cystiSim was adapted to an observed setting using field data from Tanzania, but adaptable to other settings if necessary...

Hydatid disease (echinococcosis) is a chronic, endemic helminthic disease caused by the larval stage of the tapeworm, Echinococcus granulosus. This disease is endemic in many parts of the world, such as the Mediterranean area, and in particular in Algeria. Helminth parasites have developed complex strategies to modulate the immune responses of their hosts through versatile immune-regulatory mechanisms. These mechanisms may regulate immune responses associated with inflammatory diseases such as inflammatory bowel diseases (IBD)...

Dogs are the hosts for a wide helminth spectrum including tapeworms, flatworms, and nematodes. These parasites affect the dog health and cause morbidity and mortality, especially in young and old animals. Some species, as Toxocara canis, Ancylostoma caninum, Dipylidium caninum, and Echinococcus spp. are well-known zoonotic parasites worldwide, resulting in high public health risks. Poor data about canine helminth species and prevalence are available in Russia, mainly due to the absence of official guidelines for the control of dog parasites...

Cestodes (tapeworms) have complex adaptations to their obligatory parasitic life-style. Among these adaptations, they show many evolutionary innovations in their development, including complex life-cycles with multiple hosts and life-stages, several independent origins of asexual reproduction, and the evolution of segmentation as a mean to generate massive reproductive output. Therefore, cestodes offer many opportunities for the investigation of the evolutionary origins of developmental novelties (evo-devo)...

Cysticercus, the larval form of Taenia Solium, a tapeworm, can infest various tissues in the human body. Though central nervous system involvement is the most dramatic form of infestation, several other uncommon sites of has been reported in the literature. One such involvement is that of the musculature. The most easily recalled manifestation of myocysticercus is that in the orbit where the patients present with painful proptosis. However, other less common muscular sites of involvement are documented in case reports...

Bovine cysticercosis is caused by Taenia saginata cysticercus, the larval stage of the human tapeworm Taenia saginata. Recent European initiatives have highlighted the poor sensitivity of current surveillance for this parasite in cattle at slaughter; calling for more targeted, risk based and cost effective methods of T. saginata cysticercus detection. The aim of this study was to provide evidence that could inform such improved meat inspection activities in the United Kingdom (UK). The study included three components: (i) a farm-level case control study; (ii) the characterization of the network of movements of T...

Taeniasis/cysticercosis caused by the tapeworm Taenia solium is a parasite disease transmitted among humans and pigs, the main intermediate host. The larvae/cysts can lodge in several tissues of the pig, i.e. skeletal muscles and different locations of the central nervous system. The molecular mechanisms associated to tissue preferences of the cysts remain poorly understood. The major public health concern about this zoonosis is due to the human infections by the larval form in the central nervous system, causing a highly pleomorphic and debilitating disease known as neurocysticercosis...
