Nosema distribution across Portugal. Results from the first nationwide survey (...

Pires, Sância; Murilhas, António; Russo, Paulo; Valério, Maria; Gonçalves, Manuel

A nationwide field sampling exercise was launched in 2011, to address mounting anecdotal evidence of atypically high honey bee colony mortalities of unexplained origin occurring throughout Portugal. The first approach was to contact 662 beekeepers (≈ 4% of the registered Portuguese beekeepers), via telephone interviews with a view to formulating an 'educated guess' regarding the cases where Nosema apis / Nosema...

Nosema distribution across Portugal. Results from the first nationwide survey (...

Pires, Sância; Murilhas, António; Russo, Paulo; Valério, Maria; Gonçalves, Manuel

Nosemosis is not a recent pathology in Portugal. The etiological agent traditionally associated with it, the microsporidian Nosema apis, is well characterized and was not causing considerable economic damage to the Portuguese apiculture. However, the recent arrival, to the ‘European’ honeybee sphere, of a ‘new’ Nosema species (N. ceranae) has been recurrently considered a relevant contribution to the ‘Colony Co...

Pires, Sância; Murilhas, António; Russo, Paulo; Valério, Maria; Gonçalves, Manuel

To investigate claims of abnormally high honey bee colony mortality in Portugal during 2011, a survey was carried out via telephone interviews. It included 662 (≈ 4%) registered Portuguese beekeepers and followed the basic 'Coloss' questionnaire. Interviewees were selected accounting for total numbers of colonies and the geographical distribution of their apiaries across the country. The 'sampling grid' was set...

Pires, Sância; Murilhas, António; Russo, Paulo; Valério, Maria; Gonçalves, Manuel

Since winter 2006, extensive honey bee colony losses with distinctive features were first reported in the USA ( ‘Colony Collapse Disorder’, CCD). Global research over the past few years attempting to pin point CCD’s most likely causes, recurrently pointed out that no single factor is universally responsible for this disorder. Nevertheless, stressors e.g. the Varroa mite, some ‘new generation’ pesticides, an eve...

Monitoreo nacional de la nosemosis - resultados previos del proyecto portugal, ...

Pires, Sância; Murilhas, António; Almeida, Paulo; Valério, Maria

Considering the growing number of reports implicating Nosema ceranae in colony morbidity/mortality, it is relevant to clarify the current epidemiology of Nosemosis in Portugal beekeeping context, pinpointing the etiologic agents to the species level and, eventually, identifying possible intra-specific types. About 2% of the registered Portuguese apiaries were sampled in two consecutive years (2011 and 2012)...

PBN - Portugal, beekeeping and nosema

Pires, Sância; Almeida, Paulo R.; Murilhas, António; Valério, Maria José

This work aims at carrying out a survey to assess the prevalence of Nosema sp in Portugal. There has been an increasing number of positively lab-identified cases of Nosema in Bee Pathology Laboratories across the country in recent years. However, the optical microscopy methods that have been used are unreliable to identify the species of Nosema. Considering the growing number of reports implicating Nosema cera...

Investigação em apicultura em Portugal: Portugal, apicultura e Nosema

Pires, Sância; Murilhas, António; Russo, Paulo; Valério, Maria José

A Nosemose é uma doença das abelhas melíferas (Apis mellijera L.), cujo agente etiológico tradicional, (o microsporídio unicelular Nosema apis Zander), foi identificado há cerca de cem anos (Paxton, 2010). Considerada uma das patologias mais predominante e prejudicial para as abelhas ocidentais, tem sido intensamente estudada (apesar de nem sempre ser evidente, face a uma sintomatologia relativamente inaparente...

Prevalence and geographical distribution of Senotainia tricuspis (Meigen)

Pires, Sância; Cadavez, Vasco; Valério, Maria José

The aim of this work was to survey the prevalence of Senotainia sp. (Diptera, Sarcophagidae) in several Portuguese regions. A total of 61182 bees were sampled from 1912 Portuguese apiaries, distributed in several regions of Portugal and were analyzed for Senotainia sp prevalence. The bees samples were collected during 2009 and the thoraxes of 40 bees taken from each sample were examined individually in Referenc...

Pires, Sância; Paulos, Katia; Cadavez, Vasco; Valério, Maria José

EI objetivo de este trabajo fue determinar la prevalencia y la dispersión de las enfermedades de cría de las abejas en el Noreste de Portugal. Muestras de cría de abejas melíferas fueron recogidas y enviadas al laboratorio de Patología Apícola de la Eso la Superior Agraria de Bragança (LPAESAB). Dichas muestras fueron recogidas en los años 2008 y 2009 Y se procesaron para la evaluación de las enfermedades de la...

Marcadores do metabolismo ósseo em gatos

Cardoso,Mauro José Lahm; Costa,Fabiano Séllos; Muniz,Lucy Marie Ribeiro; Melussi,Maíra; Valério,Maria Aparecida

A formação e reabsorção óssea são processos contínuos no organismo e uma das maneiras de avaliar as alterações, a intensidade ou alterações desse processo é pela mensuração dos marcadores do metabolismo ósseo no soro ou na urina. Os objetivos deste estudo foram identificar se os testes comerciais para detectar osteocalcina (OC), peptídeo aminoterminal do procolágeno tipo I (PINP) e telopeptídeo carboxiterminal ...
