Tapeworms Taenia solium and Taenia saginata are the causative agents of taeniasis/cysticercosis. These are diseases with high medical and veterinary importance due to their impact on public health and rural economy in tropical countries. The re-emergence of T. solium as a result of human migration, the economic burden affecting livestock industry, and the large variability of symptoms in several human cysticercosis, encourage studies on genetic diversity, and the identification of these parasites with molecular phylogenetic tools...

Cysticercosis, a leading cause of acquired epilepsy in developing countries, has been controlled or eradicated in industrialized countries. This paradigm has recently been challenged, with human neurocysticercosis (NCC) being increasingly diagnosed in these countries. In order to assess the NCC burden in Portugal, a retrospective study on NCC hospitalizations (2006-2013) was conducted based on the national database on hospital morbidity: 357 hospitalized cases were detected. NCC was most frequent in the following age groups: 20-64 years (n = 197, 55·2%) >64 years (n = 111, 31·1%), and <20 years (n = 49, 13·7%)...

An epidemiological study on taeniasis and cysticercosis in northern India has recently updated the epidemiology of Taenia asiatica. Practically, all the detected cases of taeniasis were caused by T. asiatica, cited for the first time in humans in that country. The finding widens the geographical distribution of T. asiatica, a species wrongly considered an exclusive South-Eastern Asian parasite. Due to the introduction of molecular techniques in Taenia diagnosis, the species is slowly showing its true distribution...

Taenia solium is the major cause of taeniasis and cysticercosis/neurocysticercosis (NCC) in the developing countries including India, but the existence of other Taenia species and genetic variation have not been studied in India. So, we studied the existence of different Taenia species, and sequence variation in Taenia isolates from human (proglottids and cysticerci) and swine (cysticerci) in North India. Amplification of cytochrome c oxidase subunit 1 gene (cox1) was done by polymerase chain reaction (PCR) followed by sequencing and phylogenetic analysis...

BACKGROUND: Taeniasis and cysticercosis are major causes of seizures and epilepsy. Infection by the causative parasite Taenia solium requires transmission between humans and pigs. The disease is considered to be eradicable, but data on attempts at regional elimination are lacking. We conducted a three-phase control program in Tumbes, Peru, to determine whether regional elimination would be feasible. METHODS: We systematically tested and compared elimination strategies to show the feasibility of interrupting the transmission of T...

The prevalence of taeniasis was determined during the period January to April 2013 in a cross-sectional study of non-descript domestic dogs from the livestock-wildlife ecosystem of Ngorongoro, Tanzania. Taeniid eggs were determined by screening faecal samples using the formalin-ether sedimentation technique. Predisposing factors for dog infection were assessed in relation to demographic, husbandry and management data. Of the 205 faecal samples screened, 150 (73.2%) were positive for taeniid eggs. The prevalence of dogs harbouring taeniid eggs was 80%, 30...

We report a case of neurocysticercosis concurrent with taeniasis in a 31-year-old woman. The patient presented with a headache and diplopia. Oculomotor disturbances with a left adduction deficit were observed. Fundoscopy revealed papilledema. Additionally, computed tomography of the brain revealed more than 20 small cysts within the parenchyma, most of which were associated with ring enhancement. Moreover, serum antibody testing (Western blotting) for Taenia solium-cysticerci was positive. The patient received albendazole and corticosteroids, and progressive resolution of the neurological symptoms and papilledema was observed starting approximately three days after administration...

Taenia solium taeniasis/cysticercosis is a neglected parasitic zoonosis with significant economic and public health impacts. Control measures can be broadly grouped into community health education, improvements in hygiene and sanitary conditions, proper meat handling at household and community level, improved standards of meat inspection, pig management, treatment of individual patients and possibly human populations, and treatment and/or vaccination of porcine populations. This manuscript looks critically into currently existing control options and provides suggestions on which (combination of) tools would be most effective in the control of T...

INTRODUCTION: It has been reported that behavioral changes relate to infection in different parasitoses. However, the relation between the extent of the behavioral changes and the magnitude of the infection has been scarcely studied. The aim of this study was to evaluate the relationship between different doses of infection and the behavioral changes induced in the experimental Taenia pisiformis taeniasis in golden hamsters. METHODS: Groups of nine hamsters were infected with three or six T...

Puag-Haad is a traditional anthelmintic drug used to treat taeniasis in Thailand and Lao PDR. It is derived from the aqueous extract of the plant Artocarpus lakoocha. We investigated the in vitro anthelmintic properties of Puag-Haad against Schistosoma mansoni. Adult worms were incubated in M-199 medium containing 250, 500 and 750 μg/ml of Puag-Haad or praziquantel (PZQ) at a concentration of 175 μg/ml for 3, 6, 12 and 24 hours. The relative motility (RM value), survival index (SI) and tegument alterations seen under scanning electron microscope were assessed at each incubation time...

Complicated Taeniasis necessitating surgical intervention is extremely rare and is usually reported to occur in the distal ileal region of the Gastrointestinal tract. A case of peritonitis secondary to proximal jejunal perforation due to Taenia saginata is presented. Preoperative evaluation suggested the diagnosis of acute duodenal ulcer perforation. Although no real change in management and outcome is present, Taenia remains an exceptional direct cause of intestinal perforation, and should be kept on the list of differential diagnosis of peritonitis and acute abdomen in endemic geographical locations...

BACKGROUND: Taenia solium, a parasitic cestode that affects humans and pigs, is the leading cause of preventable epilepsy in the developing world. T. solium eggs are released into the environment through the stool of humans infected with an adult intestinal tapeworm (a condition called taeniasis), and cause cysticercosis when ingested by pigs or other humans. A control strategy to intervene within high-risk foci in endemic communities has been proposed as an alternative to mass antihelminthic treatment...

BACKGROUND: Taenia solium infections are mostly endemic in less developed countries where poor hygiene conditions and free-range pig management favor their transmission. Knowledge on patterns of infections in both human and pig is crucial to design effective control strategies. The aim of this study was to assess the prevalence, risk factors and spatial distribution of taeniasis in a rural area of the Democratic Republic of Congo (DRC), in the prospect of upcoming control activities. METHODS: A cross-sectional study was conducted in 24 villages of the health zone of Kimpese, Bas Congo Province...

Following confirmation that a remote village of approximately 300 inhabitants in northern Lao PDR was hyperendemic for the Neglected Tropical Disease Taenia solium, a pilot human-porcine therapeutic control intervention was implemented between October 2013 and November 2014. Mass drug administration with a three day albendazole 400mg protocol was offered to all eligible humans in October 2013 and March 2014. At these times, and again in October 2014, eligible village pigs received the anti-cysticercosis TSOL18 vaccination and an oral dose of oxfendazole anthelmintic at 30mg/kg, both repeated one month later...

La carta al editor se refiere al artículo de Canaval-Zuleta et al. aceptado para publicación, titulado "Endoscopy as an alternative diagnostic and therapeutic technique for Taenia saginata". El trabajo presenta una serie de incorrecciones que deben ser aclaradas, o al menos parte de ellas en solo 300 palabras. La información sobre las vias de infeccion en taeniasis, así como la patogenia y técnicas de diagnóstico, no se ajustan a la realidad. Asimismo, ya está publicado que el diagnóstico por endoscopia es una técnica muy sensible pero nada específica, pues no permite distinguir entre las 3 especies humanas del género Taenia...

We report here a human case of Taenia asiatica infection which was confirmed by genetic analyses in Dali, China. A patient was found to have symptoms of taeniasis with discharge of tapeworm proglottids. By sequencing of the mitochondrial cytochrome c oxidase subunit 1 (cox1) gene, we observed nucleotide sequence identity of 99% with T. asiatica and 96% with T. saginata. Using the cytochrome b (cytb) gene, 99% identity with T. asiatica and 96% identity with T. saginata were found. Our findings suggest that taeniasis of people in Dali, China may be mainly caused by T...

Human taeniasis/cysticercosis caused by the pork tapeworm Taenia solium has been identified as a potentially eradicable disease by the International Task Force for Disease Eradication of the World Health Organization. In southeast Asia, T. solium taeniasis/cysticercosis is considered one of the major neglected tropical diseases afflicting the region. In the last few decades, a considerable effort has been invested toward establishing the epidemiology and burden of disease in several southeast Asian countries...
