Moreira, Fernando; Miranda, Alice; Pinto, Maria de Lurdes; Coelho, Adosinda; Matos, Manuela; Monteiro, José Manuel; Coelho, Ana CláudiaAn epidemiological dermatophytosis survey was carried out in farmed rabbits with alopecia in Northern and Central Portugal. Between August and October 2008, samples from suspected clinical cases of alopecia in meat rabbits on industrial farms were collected and cultured by conventional methods. Effects on the prevalence of several variables, such as breed, age, month of sample collection, configuration of the l...
Cost-benefit analysis of sheep and goat brucellosis vaccination with Rev.1 in t...
Coelho, Adosinda; Pinto, Maria; Coelho, AnaIn the North of Portugal, a mass vaccination programme of small ruminants was conducted from 2001 to 2004. A study of cost-benefit was carried out for the 2000/2005 period to ascertain the economic benefits of this strategy. In order to estimate the cost of the zoonosis, the compensation costs paid to farmers for culled animals in the Brucellosis Eradication Campaign, data from vaccine Rev. 1 costs, and costs o...
A seroepidemiological survey of Mycobacterium avium subsp. paratuberculosis in ...
Coelho,Ana C; Pinto,Maria L; Coelho,Adosinda M; Aires,Alfredo; Rodrigues,JorgeThe aim of this study was evaluate the risk factors for Mycobacterium avium subsp. paratuberculosis (Map) seroprevalence in sheep in the North of Portugal. The effects on seroprevalence of several variables such as individual characteristics, management practices, farm characteristics, animal health, and available veterinary services were evaluated. This information was then used in a multivariable logistic reg...
Comparative evaluation of PCR in Ziehl-Neelsen stained smears and PCR in tissue...
Coelho, Ana Cláudia; Pinto, Maria de Lurdes; Miranda, Alice; Coelho, Adosinda; Pires, Maria dos Anjos; Matos, ManuelaThirty six tissues from sheep, previously diagnosed with paratuberculosis, were tested by PCR in positive Ziehl-Neelsen staining smears of tissues, and PCR in tissues targeting IS900 specific for Mycobacterium avium subsp. paratuberculosis. DNA amplification was achieved in 33.3% Ziehl-Neelsen smears, and in 61.1% tissue samples. Combination of both techniques found 66.7% samples as positive. Combination of tec...
Comparação de duas técnicas de isolamento do Mycobacterium avium subsp. paratub...
Coelho,Ana Cláudia; Pinto,Maria de Lurdes; Coelho,Adosinda Maria; Rodrigues,JorgeA paratuberculose é uma enterite crônica granulomatosa causada por Mycobacterium avium subsp. paratuberculosis que afeta principalmente os ruminantes. A cultura de bactérias a partir de amostras de fezes e tecidos constitui um dos métodos mais eficazes de diagnóstico, sendo ainda o único método disponível para obtenção de isolamentos e estirpes de micobactérias. Contudo, este método apresenta baixa sensibilidad...
