Neurocysticercosis is a major cause of epilepsy in countries where Taenia solium is endemic and the parasite is a major cause of food-borne disease globally. Pigs are the natural intermediate host involved in transmission of the parasite. T. solium is known to be endemic in Nepal, however there is limited reliable data about the prevalence of the disease in Nepal. The aim of this study was to determine accurately the prevalence of porcine cysticercosis in slaughter age pigs in an area of Nepal where pigs are known to be free-roaming...

BACKGROUND: Taenia solium and Taenia saginata are zoonotic parasites of public health importance. Data on their occurrence in humans and animals in western Europe are incomplete and fragmented. In this study, we aimed to update the current knowledge on the epidemiology of these parasites in this region. METHODS: We conducted a systematic review of scientific and grey literature published from 1990 to 2015 on the epidemiology of T. saginata and T. solium in humans and animals...

Neglected tropical diseases caused by helminth infections currently affect millions of people worldwide. Among them, there are three tapeworm species of outstanding importance: Echinococcus granulosus, E. multilocularis, and Taenia solium, which are responsible for cystic echinococcosis, alveolar echinococcosis, and cysticercosis, respectively. Despite several attempts, there is still a need for an effective and low-cost serological diagnostic test that can be used in endemic countries. In the present work, we described an innovative bioinformatic workflow for a rational prediction of putative peptide candidates for one-step serological diagnosis of any of these infections...

Cysticercosis is a systemic parasitic infestation caused by ingesting the eggs of the pork tapeworm, Taenia solium. The central nervous system (CNS) is the most important primary site of infection and disease can present with solitary or multiple space-occupying lesion. Other organs like subcutaneous tissues, muscles, heart, liver, lungs, and peritoneum are more frequently affected but maxillofacial region involvement is rare. The diagnosis of cysticercose is evoked on US examination and CT scan, but confirmation is only possible by Fine needle aspiration cytology [FNAC] or histological examination in case of surgical removal of the oral lesion which can identify the Taenia solium larva...

BACKGROUND: Taenia solium, the cause of neurocysticercosis (NCC), has significant socioeconomic impacts on communities in developing countries. This disease, along with taeniasis is estimated to infect 2.5 to 5 million people globally. Control of T. solium NCC necessitates accurate diagnosis and treatment of T. solium taeniasis carriers. In areas where all three species of Taenia tapeworms (T. solium, Taenia saginata and Taenia asiatica) occur sympatrically, conventional microscope- and copro-antigen based diagnostic methods are unable to distinguish between these three Taenia species...

Neurocysticercosis is a parasitic infection of the central nervous system with the cysts of Taenia solium, the pig tapeworm. Infection presents with a pleomorphic picture depending on the stage and location of the infection and the immune response of the infected host. Historically confined to the developing world, neurocysticercosis is no longer limited to endemic regions, as globalization, travel, and immigration permit the spread of the infection. We report a young Hispanic patient who was diagnosed with neurocysticercosis of the fourth ventricle and subsequent hydrocephalus...

Human cysticercosis (CC) is a parasitic zoonosis caused by the larval stage (cyst) of the Taenia solium. Cysts can establish in the human central nervous system (neurocysticercosis, NCC) and other organs and tissues; they also develop in pigs, the natural intermediate host. Human taeniosis may be caused by T. solium, Taenia saginata and Taenia asiatica tapeworms; these infections are usually asymptomatic, but show a significant relevance as they perpetuate the parasites' life cycle, and, in the case of T. solium, they are the origin of (N)CC...

From January 2011 until September 2016, screening of taeniasis carriers was carried out in a town in Gianyar District (Taenia saginata) and in villages which consisted of several Banjars (the smallest community units) on the eastern slope of Mt. Agung, Karangasem District (Taenia solium) in Bali, Indonesia. Fecal samples from all community members who chose to participate were examined microscopically for detection of taeniid eggs each person completedwith a questionnaire to determine if they had seen whitish, noodle-like proglottids (anamnesis) in their feces...

Lack of knowledge is one of the main risk factors for the spread of the zoonotic parasite Taenia solium. The computer-based health-education tool 'The Vicious Worm' was developed to create awareness and provide evidence-based health education as a specific measure in control strategies. To increase the reach of the tool, a new version in Swahili was developed and can now be downloaded for free from http://theviciousworm.sites.ku.dk.

Human taeniasis is a zoonotic condition resulting from infection with the adult stages of Taenia saginata ("beef tapeworm"), Taenia solium ("pork tapeworm") or Taenia asiatica ("Asian tapeworm"). Although these parasites have a worldwide distribution, the overwhelming burden is felt by communities in low- and middle-income countries. This is particularly true for T. solium, whereby infection of the central nervous system with the larval stage of the parasite (neurocysticercosis) is a major cause of acquired epilepsy in low-resource settings...

Hector H Garcia, Oscar H Del Brutto
Antiparasitic agents against Taenia solium cysticercosis have been in use since 1979, although its use has been questioned on the basis that cysts would die naturally and thus treatment-induced inflammation is unnecessary. In addition, isolated reports have also questioned whether neurocysticercosis (NCC) is a cause of epilepsy. After more than three and a half decades, a large body of evidence is available. Little if any doubt exists about NCC as a cause of seizures - NCC is consistently associated with seizures when appropriate groups are compared, and in a large subset of cases, seizure semiology correlates with the anatomical location of lesions...

BACKGROUND: Extraparenchymal neurocysticercosis (ExPNCC), an infection caused by Taenia solium cysticerci that mainly occurs in the ventricular compartment (Ve) or the basal subarachnoid space (SAb), is more severe but less frequent and much less studied than parenchymal neurocysticercosis (ParNCC). Demographic, clinical, radiological, and lumbar cerebrospinal fluid features of patients affected by ExPNCC are herein described and compared with those of ParNCC patients. METHODOLOGY AND PRINCIPAL FINDINGS: 429 patients with a confirmed diagnosis of neurocysticercosis, attending the Instituto Nacional de Neurología y Neurocirugía, a tertiary reference center in Mexico City, from 2000 through 2014, were included...

Neurocysticercosis is a parasitic disease that results from the larvae of Taenia solium. While neurocysticercosis is considered as the most common parasitic infection of the nervous system, spinal neurocysticercosis is rare. The present case study investigated a 59-year-old woman, who was admitted to our hospital with pain in the bilateral lower limbs and urinary complaints in the form of straining of micturition with increasing frequency. Magnetic resonance imaging revealed an intradural extramedullary lesion extending from L1/2 to S1 of the spine...

BACKGROUND: Taeniasis and cysticercosis are two diseases caused by Taenia solium, a parasite transmitted between humans and pigs, leading to considerable economic loss and disabilities. Transmission of the parasite is linked to environmental and behavioural factors such as inadequate sanitation and hygiene, poor pig management, and consumption of infected pork. This study used implementation research method to design a health education intervention strategy for reducing T. solium infections in Burkina Faso, a country endemic for the parasite...

Seizures due to neurocysticercosis (NCC) is a neglected human-to-human transmitted disorder and an emerging problem worldwide. A substantial portion of recent onset seizures is known to be attributed to NCC in Taenia solium (T. solium) endemic areas where populations which neither raise pigs nor eat pig meat are also at risk. High prevalence of NCC causing epilepsy has been reported in the underdeveloped areas of Southeast Asia (SEA) however, only fragmentary information on its incidence is available in countries like Malaysia...

MicroRNAs (miRNAs) are small non-coding RNAs that have emerged as important regulators of gene expression and perform critical functions in development and disease. In spite of the increased interest in miRNAs from helminth parasites, no information is available on miRNAs from Taenia solium, the causative agent of cysticercosis, a neglected disease affecting millions of people worldwide. Here we performed a comprehensive analysis of miRNAs from Taenia crassiceps, a laboratory model for T. solium studies, and identified miRNAs in the T...

BACKGROUND: Currently, the reference standard assay for the serodiagnosis of neurocysticercosis (NCC) is the lentil lectin-bound glycoproteins/enzyme-linked immunoelectrotransfer blot (LLGP-EITB). The main disadvantage of this technique is the complexity of obtaining and purifying the LLGP extract. This could be solved by replacement with highly specific recombinant antigens from Taenia solium. Based on previous studies, we selected and produced the recombinant Ts8B2 and T24H proteins and applied them to three diagnostic techniques: western blot (WB), enzyme-linked immunosorbent assay (ELISA) and the multiplex bead-based assay (MBA)...

Spinal cysticercosis is a very uncommon manifestation of neurocysticercosis, which is caused by the larvae of Taenia solium. Here, we present a rare case of isolated lumbar intradural extramedullary neurocysticercosis, initially thought to be Tarlov cyst. A 40-year-old man, presented with low backache for 1-year with radiation of pain to right leg for 3 months. The patient was treated successfully with the surgical removal of the cyst, followed by medical treatment. Spinal neurocysticercosis should be considered in the differential diagnosis in high-risk populations, with new symptoms suggestive of a spinal mass lesion...

Neurocysticercosis (NCC), one of the most common parasitic diseases of the central nervous system, is caused by Taenia solium. This parasite involves two hosts, intermediate hosts (pig and human) and a definitive host (human), and has various stages in its complex life cycle (eggs, oncosphere, cysticerci and adult tapeworm). Hence, developing an animal model for T. solium that mimics its natural course of infection is quite challenging. We have reviewed here the animal models frequently used to study immunopathogenesis of cysticercosis and also discussed their usefulness for NCC studies...
