Use of flubendazole and fenbendazole for treatment of lung severe infection by the gapeworm cyathostoma bronchialis (Nematoda: Syngamidae) in branta hutchinsii, anser indicus and b. leucopsis exotic geese: An interesting case
Full text linkA 6-year-old female goose (Branta hutchinsii) from a group of ornamental exotic geese was found dead due to severe respiratory failure, followed by emission of haemorrhagic sputum and blood clots from the beak and nostrils, and then collapse. At necropsy, the cause of death was attributed to a total of 76 helminth parasites found in the trachea and lungs, then identified as Cyathostoma bronchialis. The flock was initially treated by feed with flubendazole (1200 g/1000 kg/feed) for 7 consecutive days but, at the reappearance of the respiratory symptoms 10 days after, the animals were given fenbendazole by drinking water (300 mg/L) for 7 consecutive days, but at the reappearance of the respiratory symptoms 10 days after, the animals were given fenbendazole via drinking water (300 mg/L) for 7 consecutive days. Despite these treatments, the respiratory symptoms continued to relapse 10–15 days after the end of drug administration. In the literature, there are no data regarding drugs for the treatment of C. bronchialis infestations in geese, and the use of these drugs in exotic birds occurs as “off-label” use. This case study provides information on C. bronchialis life cycle, which is still poorly studied and poorly documented today. In particular, the case provides useful suggestions for evaluating an appropriate protocol for the treatment of C. bronchialis in geese
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Virological Investigation of Avian Influenza Virus on Postglacial Species of Phasianidae and Tetraonidae in the Italian Alps
Full text linkLand-based birds, belonging to Galliformes order are considered to be potential intermediaries in the emergence of new strains of
influenza A viruses (AIVs), but the viral circulation in these birds remains largely unknown. To gain insights into the circulation
of AIV in the wild Galliformes populations in Italian Alps, we conducted a virological survey on rock partridge (Alectoris graeca
saxatilis) belonging to Phasianidae family and on tetraonids including rock ptarmigan (Lagopusmutus helveticus) and black grouse
(Tetrao tetrix tetrix). In 2003 and 2004, during the hunting seasons, 79 wild Galliformes, categorised into age and sex classes,
were hunted in the Sondrio Province (Central Alps). Cloacal swabs were collected from 11 rock partridges and from 68 tetraonids
including 23 alpine rock ptarmigans and 45 black grouses.We tested cloacal swabs by a high sensitive reverse transcription- (RT-)
PCR detecting thematrix gene of AIV.No AIV was detected in the investigated samples, thus, suggesting the lack of AIV circulation
in these relict populations in the study period. In terms of threatened species conservation, during wildlife management activities,
it is very important to exclude the introduction of AIV-carrier birds in shared territories, a fact representing a health risk for these
populations
Bovine papillomatosis hiding a zoonotic infection: Epitheliotropic viruses in bovine skin lesions
Full text linkWe describe two cases of skin co-infections with epitheliotropic viruses, detected in two cattle during lumpy skin disease (LSD) surveillance in northern Italy. A diagnostic protocol including different molecular methods as well as negative staining electron microscopy was applied to detect the most common viral agents belonging to the family Papillomaviridae, Poxviridae and Herpesviridae which cause skin diseases in cattle. Two specimens were collected from cases clinically diagnosed as papillomatosis and pseudo-LSD. Both skin lesions were shown to harbor more than one viral species. This case report shows, for the first time, co-infection of zoonotic parapoxvirus with bovine papillomavirus and herpesvirus in skin lesions of cattle. In particular, the simultaneous presence of virions morphologically referable to parapoxvirus and papillomavirus confirms that the replication of both viruses in the same lesion can happen and the so-called papillomatosis can bear zoonotic viruses
