The Asian Taenia and the possibility of cysticercosis
2000
In certain Asian countries, a third form of human Taenia, also known as the Asian Taenia, has been discovered. This Asian Taenia seems to be an intermediate between Taenia solium and T. saginata since in morphological terms it is similar to T. saginata, yet biologically, as it uses the same intermediate host (pigs), it is more akin to T. solium. Taenia solium causes human cysticercosis, while T. saginata does not. It is not known whether the Asian taeniid is able to develop to the larval stage in humans or not. The arguments proposed by those authors who consider it unlikely that the Asian Taenia causes human cysticercosis are: (a) its molecular similarities with T. saginata; (b) the absenc…
The influence of adult worm age and definitive host on the transmission of Echinostoma caproni: egg hatchability and miracidial infectivity.
2012
AbstractWe analysed the influence of different ages of Echinostoma caproni adult worms reared in different definitive host-species on egg hatchability and miracidial infectivity. Eggs obtained from 2-, 4- and 6-week-old adult worms collected from rats, hamsters and mice, hatched miracidia that were used to infect laboratory-reared specimens of Biomphalaria glabrata. Highest egg hatchability was obtained with eggs derived from hamsters and mice. Egg hatchability did not seem to be affected by the age of E. caproni adult worms. Miracidial infectivity was not affected by the definitive host species. However, miracidial infectivity was affected by the age of adult worms when they developed in t…
MM3-ELISA evaluation of coproantigen release and serum antibody production in sheep experimentally infected with Fasciola hepatica and F. gigantica.
2008
During an experimental infection of sheep with Fasciola hepatica or F. gigantica, MM3-SERO and MM3-COPRO ELISA tests were applied to compare the kinetics of antibody production and coproantigen release between the 2nd and 32nd week post-infection (wpi). The Kato-Katz technique was used to measure the kinetics of egg shedding by both Fasciola species (eggs per gram of feces, epg). The kinetics of IgG antibodies for all sheep infected with F. hepatica and F. gigantica followed a similar pattern. Optical density (OD) increased rapidly between the 4th until the 12th wpi, when the highest values were reached and then decreased slowly until the 32nd wpi. Coproantigen levels increased above the cu…
Fasciola gigantica transmission in the zoonotic fascioliasis endemic lowlands of Guilan, Iran: experimental assessment.
2014
The lowland flatlands around the city of Bandar-Anzali, at the Caspian Sea shore, Guilan province, are an endemic area where Fasciola gigantica appears to be the fasciolid species involved and past outbreaks affecting around 15,000 people and the highest human infection rates in Iran have been reported. Fascioliasis transmission in that area has been experimentally analysed for the first time, by means of assays of monomiracidial (Group A: 120 snails) and pentamiracidial (Group B: 96 snails) infections of local Radix lymnaeid snails with a local cattle F. gigantica isolate. Ribosomal DNA ITS-2 sequencing proved that Lymnaea (Radix) gedrosiana should henceforth be considered a synonym of Rad…
Identifikasi Telur Cacing pada Saluran Pencernaan Satwa Liar yang Dipelihara Masyarakat di Manokwari, Papua Barat
2021
Investment of parasitic worms of captive wildlife was an impact on their health condition. This study was conducted to determine the intensity of parasitic worm infection in wild animals kept by communities in Manokwari, West Papua. The Natif method was used, by centrifuge of 20 birds and 20 mammals (Kangaroo and Deer) faeces collected from the sites. Sampling was carried out from October to November 2016. The analysis of collected faecal samples showed that bird species were not indicated (negatively infected by worm). In mammals, Nematodes and cestodes were found. Identification of existing findings showed that 3 (three) types of worm eggs were found, namely Taenia sp in kangaroos (Macrop…
Visiting the King of the World
2009
Apsilankymas pas Pasaulio karalių – tai tema, kuri bent paviršutiniškai supažindina su egzistuojančiais daugiau ar mažiau ezoteriniais pasakojimais, kartais net gana fantastiškais, kuriuose kalbama apie viršžmogiškosiomis galiomis apdovanotas būtybes, gyvenančias, atrodo, žemės gelmėse, Azijos žemių platybėse, Himalajų regione, Mongolijoje ar Tibete. „Pasaulio karalius“ – pavadinimas 1927 m. parašyto veikalo, kurio autorius René Guénonas – prancūzų ezoterikas ir mistikas, gimęs 1886 m. Blois, miręs 1951 m. Kaire. Iš literatūros kūrinių – ir kelionių aprašymų, ir fantastinių romanų – be Jules‘io „Kelionės į žemės centrą“ galima paminėti Ferdinando Ossendowskio knygą „Gyvuliai, žmonės ir diev…
Escenarios tecnológicos con dispositivos móviles para la acción educativa. Tendencias y vínculos con la imagen
2021
Presentamos un acercamiento a los escenarios educativos con TIC en la actualidad, en concreto tecnologías portables y modelos pedagógicos de colaboración complementarios a ellas, propios del constructivismo. La capacidad de aprendizaje que estos pueden llegar a suscitar, en cualquier momento y en cualquier lugar, refleja una realidad tangible en nuestra sociedad móvil. Nos referimos a los PLE Entornos Personales de Aprendizaje, BYOD Bring Your Own Device, la Gamificación, Flipped Classroom y la Realidad Aumentada y la Realidad Virtual. Se realiza una revisión de literatura de propuestas pedagógicas destacables, a través de algunos de los principales actores que las abordan en España. En cad…
Recent visigothic coin findings. Gold and bronze in the north of Cáceres
2017
El artículo pretende documentar una serie de monedas visigodas de oro y bronce encontradas fortuitamente dentro de la provincia de Cáceres, todas ellas de forma aislada y en solitario. La procedencia exacta de todas las piezas no se conoce del todo, aunque están circunscritas con seguridad a Cáceres. Además, dos de las monedas son inéditas: un triente pseudo-imperial a nombre de Justiniano I y un tremís de Égica y Witiza procedente de Acci. The paper aims to document a series of Visigoth gold and bronze coins fortuitously found in the province of Cáceres, all of them isolated and alone. The exact origin of all the coins is not fully known, but it is confined surely within Cáceres. Furthermo…
A Novel Histogram for Partial Discharge Signals in HV Insulating Systems
1986
A technique for relating measurable electrical quantities with energies dissipated inside a void in highly electrically stressed insulation is presented. It is based on measuring, for each apparent discharge level qe, the algebraic sum of the external energy pulses of all discharges having a value qe and occurring over some cycles of test voltage. Theoretical investigations show that the results of such external energy summations are equal to the energies dissipated in the void. A novel histogram is also suggested which relates the apparent discharge amplitudes with their respective energies in the void. Experimental tests were carried out under controlled conditions with samples of thermop…
