Perdurabilidad empresarial: concepto, estudios, hallazgos. Directory of Open Access Journals Sweden. Por otro lado, tampoco hay evidencia suficiente para sugerir alternativas que permitan a las empresas lograr ser perdurables. Tumor de Wilms: Hallazgo coincidente. MAH O Deteksi Fasciola hepatica dan Fasciola gigantica pada Kerbau Perah Fasciola hepatica dan Fasciola gigantica merupakan cacing kelas trematoda. Telur cacing ini berbentuk oval dan dilengkapi dengan operculum yang berfungsi sebagai jalan keluar larva mirasidium pada saat telur menetas.

Ukuran telur Fasciola gigantica lebih besar dibandingkan ukuran telur Fasciola hepatica. Penelitian ini bertujuan untuk mendeteksi telur cacing Fasciola Fascioliasis is a zoonotic infestation caused by the trematode fasciola hepatica.

It presents a wide spectrum of clinical pictures ranging from fever and eosinophilia to ambiguous gastrointestinal symptoms in the acute phase. However, it may often be overlooked, especially in the acute phase, because of uncertain symptoms. Fasciola hepatica can have an initial presentation similar to the presentation of malignancy. Here, we report a case of a hepatic mass caused by fasciola hepatica. State of the knowledge of flora of hepaticas of Colombia.

The Colombian hepatic flora is a very rich one. The country has more species than the whole of Africa south of the Sahara and almost twice as many as Europe. The new catalogue of the hepaticas of Colombia accepts species in 36 families and genera : species of Hepaticae and 8 species of Anthocerotae. Seroprevalence of Fasciola hepatica in cattle in Estonia. Fasciolosis, an infectious disease caused by the liver fluke Fasciola hepatica , affects grazing cattle world-wide.

Liver fluke F. This study investigated Molecular characterization and phylogenetic analysis of Fasciola hepatica from Peru. The causative agent of fasciolosis in South America is thought to be Fasciola hepatica. In this study, Fasciola flukes from Peru were analyzed to investigate their genetic structure and phylogenetic relationships with those from other countries. Fasciola flukes were collected from the three definitive host species: cattle, sheep, and pigs. They were identified as F.

Its extremely low genetic diversity suggests that the Peruvian population was introduced from other regions. Nad1 haplotypes identical to those of Peruvian F. Our results indicate that F. Future studies are required to elucidate dispersal route of F. Published by Elsevier Ireland Ltd. Los caracoles identificados fueron de la especie Thiara tuberculata, que no fue identificada como vector de F.

Con base en los resultados obtenidos se pudo determinar la presencia de F. Full Text Available The aim of this work was to investigate the occurrence of bacteria in Fasciola hepatica and into cattle biliary ducts containing the parasite. A total of 24 liver and 58 F. The Authors conclude with some related inspective consideration. Topography and distribution of ostia venae hepatica in the Their topography and distribution must be taken into account during catheterization and liver transplantation.

Full Text Available Fasciola hepatica infection challenges health, welfare and productivity of small ruminants throughout the world. The distribution of F. In order to elucidate the current scenario in terms of prevalence and intensity of F. Two consecutive field surveys in and were conducted in the three countries in the same period August-October in sheep farms in total. Harmonized procedures from farm to laboratory based on pooled samples and the highly sensitive and accurate, diagnostic FLOTAC technique were used.

The georeferenced parasitological results were modelled at the pilot area level following a Bayesian geostatistical approach with correction for preferential sampling and accounting for climatic and environmental covariates.

The observed F. Spatial patterns of F. The latent factor analysis highlighted the importance of year-to-year variation of mean temperature, rainfall and seasonality within a country, while long-term trends of temperature and rainfall dominated between countries with respect to prevalence of infection.

Fasciola hepatica is a zoonotic infection with a worldwide distribution. Autochthonous cases have not been reported in the Amazon region of Peru. Operculated eggs resembling F. Polymerase chain reaction targeting Fasciola hepatica cytochrome oxidase subunit 1 COI gene and sequencing of the products confirmed Fasciola infection. Cabada, Miguel M. Fasciola hepatica from naturally infected sheep and cattle in Great Britain are diploid.

Here the ploidy of adult F. This constitutes the first extensive analysis of the ploidy of F. These data suggest that triploidy, and by extension parthenogenesis, is rare or non-existent in wild British F.

Given that F. Informe preliminar sobre un hallazgo de restos humanos en urna. Asimismo puede evidenciarse caries e hipoplasia en el esmalte en algunas piezas dentales. Full Text Available Fasciola hepatica is not only responsible for major economic losses in livestock farming, but is also a major food-borne zoonotic agent, with million people being at risk of infection worldwide.

This parasite is sophisticated in manipulating the hosts' immune system to benefit its own survival. A better understanding of the mechanisms underpinning this immunomodulation is crucial for the development of control strategies such as vaccines. Several transcriptional regulators were predicted to be significantly inhibited e. IL12 and IL18 or activated e. We hypothesize that activation of pathways relevant to fibrosis in ovine chronic infection, may differ from those seen in cattle.

Potential mechanisms behind immunomodulation in F. This dataset provides novel information pertinent to understanding of the pathological processes in fasciolosis, as well as a base from which to further refine development of vaccines.

Retirada de fasciola hepatica da via biliar principal por coledocoscopia. The authors present a rare case of hepatic fascioliasis in a female patient years-old, coming from the rural zone of Rio Grande do Sul, a southern State from Brazil.

She has presented with biliary colic, fluctuant jaundice and eosinophilia. Abdominal ultrasound has shown a dilated biliary tree with inside heterogeneous images.

At surgery we have found inside the biliary tree several Fasciola hepatica , which have been pulled out with the choledocoscope. We have proceeded with biliodigestive Controversial aspects of the life cycle of Fasciola hepatica.

Fasciola hepatica is a well-known helminth parasite, with significant economic and public health importance all over the world. It has been known since more than years ago and a considerable research work has been carried out on the life cycle of this important parasite.

In the hepatic phase of the life cycle of F. Even though the secretion of cysteine peptidases including cathepsin L and B proteases by F.

However, considering all the facts relating to the hepatic and biliary phases of the life cycle of F. According to the previously performed natural and experimental studies in different animals and human beings, the supporting and opposing evidences for the current opinion as well as the evidences that might justify the two new ideas are reviewed and discussed briefly.

In conclusion, our present knowledge about the time and quality of the entry of F. All rights reserved. Fasciola hepatica is a trematode that causes zoonosis, mainly in cattle and sheep, and occasionally in humans. Few recent studies have determined the infection status of this fluke in Korea. In August , we collected samples of freshwater snails at Hoenggye-ri upper stream and Suha-ri lower stream of Song-cheon stream in Daegwalnyeong-myeon, Pyeongchang-gun in Gangwon-do Province near many large cattle or sheep farms.

Among the samples, F. The prevalence varied between collection areas, ranging from 0. However, F. The nucleotide sequences of the 6 F. These results indicated that the prevalence of F. These results may help us to understand F.

Fasciola hepatica in snails collected from water-dropwort fields using PCR. Fasciola hepatica is a trematode that causes zoonosis mainly in cattle and sheep and occasionally in humans. Fascioliasis has been reported in Korea; however, determining F. Thus, using PCR, we evaluated the prevalence of F. Among examined snails, F. Morphologically, of collected snails were dextral shelled, which is the same aperture as the lymnaeid snail, the vectorial host for F.

Among the 12 F.
