Rodents are important intermediate and paratenic hosts for carnivore parasites, including the important zoonotic agents Toxoplasma, Echinococcus and Toxocara. Monitoring of such parasites in rodents can be used to detect increasing risks for human and veterinary public health. Rodents were trapped at four sites in Berlin, two near the city center, two at the periphery. PCRs were conducted to detect Coccidia (target ITS-1) and specifically Toxoplasma gondii (repetitive element) in brain and ascarids (ITS-2) in muscle or brain tissue...

BACKGROUND: We reviewed studies that analyzed cysticercosis (CC), neurocysticercosis (NCC) and epilepsy across Latin America, Asia and Sub-Saharan Africa, to estimate the odds ratio and etiologic fraction of epilepsy due to CC in tropical regions. METHODOLOGY: We conducted a systematic review of the literature on cysticercosis and epilepsy in the tropics, collecting data from case-control and cross-sectional studies. Exposure criteria for CC included one or more of the following: serum ELISA or EITB positivity, presence of subcutaneous cysts (both not verified and unverified by histology), histology consistent with calcified cysts, and brain CT scan consistent with NCC...

Cysticercosis is caused by the larval form of Taenia solium tape worm, cysticercus cellulose. The life cycle of T. solium consists of 2 host, the definite host is a man who harbours the adult forms of the worm in the intestine, while the intermediate host is the pig, where the larval form (cysticercus cellulose) is found in the skeletal muscle. Cysticercosis develops when human beings incidentally become the intermediate host and the eggs mature within their small intestine. The route of entry of the eggs into the human intestine may occur through autoinfection or by ingestion of contaminated food or water...

Transgenic papaya callus lines expressing the components of the S3Pvac vaccine constitute a stable platform to produce an oral vaccine against cysticercosis caused by Taenia solium or T. crassiceps. The development of effective delivery systems to cope with the reduced immunogenicity of new subunit vaccines is a priority in vaccinology. Herein, experimental evidence supporting a papaya-based platform to produce needle-free, recombinant, highly immunogenic vaccines is shown. Papaya (Carica papaya) callus lines were previously engineered by particle bombardment to express the three protective peptides of the S3Pvac anti-cysticercosis vaccine (KETc7, KETc12, KETc1)...

BACKGROUND: The pork tapeworm, Taenia solium, and associated human infections, taeniasis, cysticercosis and neurocysticercosis, are serious public health problems, especially in developing countries. The World Health Organization (WHO) has set goals for having a validated strategy for control and elimination of T. solium taeniasis/cysticercosis by 2015 and interventions scaled-up in selected countries by 2020. Timely achievement of these internationally-endorsed targets requires that the relative benefits and effectiveness of potential interventions be explored rigorously within a quantitative framework...

Cysticercosis and sparganosis are not uncommon parasitic infections in the developing world. Central nervous system infection by both cestodes can present with neurological signs and symptoms, such as seizure and mass effect, including brain hernia. Early detection and accurate diagnosis can prevent a fatal outcome. Histological examinations of brain tissues can confirm the diagnosis of cerebral cysticercosis, which differs from sparganosis by the presence of a cavitated body. We report here a case of cerebral cysticercosis which has the similar clinical and imaging findings as sparganosis...

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...

BACKGROUND: Taenia solium inflicts substantial neurologic disease and economic losses on rural communities in many developing nations. "Ring-strategy" is a control intervention that targets treatment of humans and pigs among clusters of households (rings) that surround pigs heavily infected with cysticerci. These pigs are typically identified by examining the animal's tongue for cysts. However, as prevalence decreases in intervened communities, more sensitive methods may be needed to identify these animals and to maintain control pressure...

Neglected tropical diseases (NTDs) are a diverse group of acute and chronic conditions with distinct characteristics that thrive mainly among the poorest populations, almost exclusively in tropical countries. To evaluate the relevance and impact of NTDs in a temperate area, the number and features of patients diagnosed with NTDs at the Infectious and Tropical Diseases Unit (ITDU), Azienda Ospedaliero-Universitaria Careggi, Florence, Italy between 2000 and 2015 were retrospectively reviewed. Overall 289 NTD cases were diagnosed in 283 subjects accounting for 2...

Cysticercosis is an emerging parasitic disease affecting worldwide population. There is large volume of data present in the literature for neurocysticercosis. The isolated intramuscular involvement of cysticercosis is uncommon and there are only sporadic case reports available. There is no review available in the literature which gives in detail clinicoradiological features and management of isolated intramuscular cysticercosis. Knowledge about such a presentation is important especially in developing countries and to differentiate the condition from a variety of other similar conditions...

BACKGROUND: Prevalence studies report Taenia solium cysticercosis in pig and human populations in Uganda. However, the factors influencing occurrence in smallholder pig production systems are not well documented and little is known about farmers' perceptions of T. solium cysticercosis or farmer practices that could reduce transmission. METHODS: To determine the risk factors, perceptions and practices regarding T. solium cysticercosis, a household survey using a semi-structured questionnaire was conducted in 1185 households in the rural and urban pig production systems in Masaka, Mukono and Kamuli Districts...

BACKGROUND: Neurocysticercosis is a common helminthic infection of the central nervous system and an important cause of adult-onset epilepsy in endemic countries. However, few studies have examined associations between neurologic symptoms, serology and radiographic findings on a community-level. METHODOLOGY: We conducted a population-based study of resident's ≥2 years old in a highly endemic village in Peru (pop. 454). We applied a 14 -question neurologic screening tool and evaluated serum for antibodies against Taenia solium cysticercosis using enzyme-linked immunoelectrotransfer blot (LLGP-EITB)...
