Taenia solium

The pork tapeworm Taenia solium causes human taeniasis and cysticercosis when ingested as viable cysts and eggs, respectively. Despite its high health burden in low-income countries, knowledge of the parasite in endemic areas such as Rwanda is often limited. Here, we assess whether The Vicious Worm education software can increase knowledge in endemic areas of Rwanda. A cross-sectional mixed-methods study was conducted to evaluate knowledge about T. solium among community health workers trained using the Vicious Worm education software...

Neurocysticercosis is a rarely diagnosed but significant clinical problem from infestation with taenia solium. It occurs as a result of ingestion of infested pork and the mode of transmission is usually feco-oral. It is commonly associated with non-specific neurologic manifestations expected of intracranial space-occupying lesions with its most common neurological presentation being seizures. However, its diagnosis without seizure is rarely reported. We report a recent experience in this regard and outcome of this disease which was inadvertently managed surgically...

This case demonstrates a diagnostic dilemma regarding the management of seizures in the postnatal setting. It seeks to highlight the importance of a thorough exploration of history and risk factors for females presenting with seizures in the postpartum period to ensure appropriate treatment and workup. Preeclampsia (PET) is a hypertensive disorder of pregnancy affecting 2%-8% of pregnancies worldwide. Less than 1% of females with preeclampsia experience eclamptic seizures. However, they are associated with significant mortality and morbidity...

Intraorally, cysticercosis is regarded as uncommon and a diagnostic challenge. Here, we report a diagnostic conundrum of an unusual case of innocuous appearing lesion on the tongue presenting as moderately tender swelling finally diagnosed as lingual cysticercosis, based on USG (Ultrasound), CT (Computed Tomography) findings and characteristic histopathologic features.

BACKGROUND: Antigen detection in Taenia solium cysticercosis confirms viable infection in the intermediate host (either pig or human). The reference B158/B60 monoclonal antibody (mAb)-based Ag-enzyme-linked immunosorbent assay (ELISA) has acceptable levels of sensitivity and specificity in human neurocysticercosis with multiple brain cysts, although its sensitivity is lower in cases with single brain cysts, whereas in porcine cysticercosis the assay specificity is affected by its frequent cross-reaction with Taenia hydatigena, another common cestode found in pigs...

Isolated myocysticercosis is a neglected tropical disease and a rare diagnosis, with only a handful of cases being reported in the literature. It is highlighted that recently, it has not only been limited to endemic regions but also persists globally due to widespread migration from endemic regions. We present a case of isolated myocysticercosis of the right pectoralis major without neurological involvement in a non-pork-eater. High-resolution ultrasonography is an effective method of diagnosis. Anti-helmintic drugs are effective treatment options; if not responding, surgical excision is the management of choice...

Taenia solium is the aetiological agent of taeniasis/cysticercosis, one of the most severe neglected tropical diseases (NTD) according to the World Health Organization (WHO). The life cycle of T. solium alternates between pigs (intermediate host) and humans (definitive host). In addition, humans can act as accidental intermediate hosts if they ingest infective eggs. In this case, the most severe condition of the disease occurs when parasites invade the central nervous system, causing neurocysticercosis (NCC)...

Neurocysticercosis, a parasitic infection of the central nervous system (CNS), is a significant public health issue globally, including in Brazil. This article presents a case report of a 44-year-old male patient residing in the rural area of Roraima, the northernmost region of Brazil within the Amazon Forest. The patient, with chronic HIV infection, acquired the Taenia solium helminth, resulting in neurocysticercosis development. Remarkably, the diagnosis of neurocysticercosis was not initially apparent but emerged through meticulous analysis following a motorcycle accident...

Neurocysticercosis (NCC) is a common parasitic disease of the central nervous system (CNS) in low- and middle-income countries. The infection is pleomorphic, caused by the larval form of the cestode, Taenia solium , and part of the heterogeneity of its clinical presentations is associated with the localization of the parasite within the CNS. Changes in the current epidemiological trends of NCC indicate that extra-parenchymal NCC is proportionally becoming more frequent. Extraparenchymal NCC is commonly accompanied by raised intracranial hypertension due to hydrocephalus, which is an emergency requiring cyst extirpation by surgical intervention to relieve the symptoms...

Biliary taeniasis is uncommon in clinical practice. We report two cases in our hospital. The first patient was diagnosed with acute biliary pancreatitis. Endoscopic retrograde cholangiopancreatography (ERCP) showed a white, flat, segmented 1-cm-wide tapeworm drilling into the duodenal papilla that was identified as Taenia saginata. After tapeworm removal, bile duct sweeping, and anthelmintic therapy, the patient recovered uneventfully. The second patient was diagnosed with acute cholangitis and multiple stones in the common bile duct and gallbladder...

Taenia solium can cause human taeniasis and/or cysticercosis. The latter can in some instances cause human neurocysticercosis which is considered a priority in disease-control strategies and the prevention of mental health problems. Glutathione transferases are crucial for the establishment and long-term survival of T. solium; therefore, we structurally analyzed the 24-kDa glutathione transferase gene (Ts24gst) of T. solium and biochemically characterized its product. The gene promoter showed potential binding sites for transcription factors and xenobiotic regulatory elements...

Taenia solium remains among the major causes of epilepsy in sub-Saharan Africa. Understanding the geospatial distribution of the parasite is important to inform control strategies. This study assessed spatiotemporal changes in the T. solium infection among pigs from a rural area in southwestern Tanzania. Secondary data from a previous repeated cross-sectional study in the Mbeya and Mbozi districts were used, involving sixteen villages, eight from each of the two districts. Serum samples were collected from 482, 460, and 421 pigs in 221, 196, and 139 households, respectively, at seven-month intervals...

Neurocysticercosis (NCC) is considered a significant health concern in developing countries in parts of Asia, Africa, and Central and South America. However, with the increased immigration, it is now becoming increasingly prevalent in the United States. NCC has psychiatric implications often neglected and not recognized in the initial diagnostic workup of patients from developing countries suffering from seizures and psychiatric illnesses, such as depression. This case report aims to signify the presentation of NCC and illustrate the importance of the psychiatric manifestations of NCC in patients...

BACKGROUND Cysticercosis is a condition caused by infection with the larval form of Taenia solium, a pork tapeworm that uses pigs as an intermediate host. Humans become infected when they ingest water or food contaminated with tapeworm cysts. Cysticercosis is increasing in frequency in developed countries due to increased access to travel. Neurocysticercosis occurs when Taenia solium cysts embed within the nervous system. The clinical presentation of neurocysticercosis ranges from asymptomatic to life-threatening, largely depending on the brain parenchymal involvement...

Cysticercus cellulosae is the larval form of Taenia solium. The disease is transmitted by faecoral route by consumption of eggs from contaminated food. Sonography & CT neck-well-defined, cystic lesion with hyperechoic area suggestive of a scolex. FNAC revealed non human like cells, fibrillation stroma, inflammatory cells. Treatment includes antiparasitic therapy, steroids.

INTRODUCTION: Cysticercosis leads to a cyst formation known to occur due to the Taenia solium parasite. Patients normally present with seeding and formation of the cysts in the central nervous system (CNS) as neurocysticercosis (NCC). Intramuscular cysts are rare presentations and are mostly incidental findings in NCC patients. We present a rare case of a rapidly progressing isolated cysticercosis of the flexor digitorum profundus (FDP) muscle leading to a pseudotumor and presenting with pseudo-Volkmanns contracture and a positive Volkmanns sign...

OBJECTIVE: To investigate the prevalence and epidemiological characteristics of taeniasis and cysticercosis among residents in Tibetan agricultural areas of Sichuan Province, so as to provide insights for the prevention and control of taeniasis and cysticercosis. METHODS: From 2016 to 2022, Kangding City, Daocheng County, Derong County, Ruoergai County and Muli Tibetan Autonomous County were sampled from Tibetan agricultural areas of Ganzi Tibetan Autonomous Prefecture, Aba Tibetan and Qiang Autonomous Prefecture and Liangshan Yi Autonomous Prefecture in Sichuan Province, and 1 to 6 townships were sampled from each county (district), followed by 4 to 7 villages sampled from each township...

Taenia solium cysticercosis and taeniosis (TSCT) are two forms of a zoonotic disease caused by T. solium tapeworm. Towards promotion of a One Health approach to the control of TSCT, we assessed TSCT reporting in the medical and veterinay sectors in Tanzania. We conducted a cross-sectional study between January and April 2020 in Babati and Mbulu districts (northern Tanzania), Kongwa district (central Tanzania), Mbinga and Nyasa districts (southern Tanzania), and the Zonal Veterinary Centres in Iringa (southern Tanzania) and Arusha (northern Tanzania) regions...

INTRODUCTION: Cysticercosis is a parasitic infestation caused by Taenia solium , which is a pork tape worm. Humans are the definitive host, and pigs are the intermediate host. It is more prevalent in low socioeconomic regions with poor hygiene and among populations where undercooked pork is consumed. CASE PRESENTATION: We hereby report an uncommon site of cyst lodgment and duration of presentation in a 24-year-old male who presented with a firm, non-tender mass over the superomedial aspect of the right orbital rim, superior to the medial canthal tendon for the last 9 years...

BACKGROUND: Taeniasis, is a worldwide foodborne zoonotic disease caused by two principal species; Taenia saginata and Taenia solium. The tapeworm infects the intestine causing taeniasis in humans. Taeniasis is a very rare parasitic infection in Palestine with very few annual cases of unknown species. The infection rate and the disease status are not clear due to the lack of reports about the actual number of patients. CASE PRESENTATION: Two Palestinian patients; one male of 22 years old from Hebron and the other is female of 33 years old from Ramallah were referred to Palestinian Health Services in the West Bank, Palestine, complained of weight loss, abdominal pain and presence of motile segments of creamy color in the their stool...
