Epidemiological survey of dermatophytosis in meat rabbits with alopecia in Port...

An 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...

Diagnosis of Mycobacterium avium complex in granulomatous lymphadenitis in slau...

The aim of this study was to compare two diagnostic methods for the detection of Mycobacterium avium complex (MAC) infection in lymph nodes with granulomatous lymphadenitis from slaughtered domestic pigs. Fifty affected lymph nodes were collected from 50 pigs and examined microscopically and by polymerase chain reaction (PCR). Microscopically, granulomatous lesions were observed in 92% of the samples, consistin...

Importância dos Saca-Rabos (Herpestes Ichneumon) como Reservatório de Mycobacte...

Poster apresentado nas IV Jornadas de Genética, realizadas na UTAD, Vila Real, nos dias 1,2 e 3 de Março de 2012. ; Os saca-rabos (Herpestes ichneumon) também conhecidos por mangustos, são carnívoros diurnos selvagens que juntamente com a geneta (Genetta genetta) representam os exemplares da família Viverridae em Portugal. É uma espécie cinegética de caça menor que se alimenta de coelhos, roedores, aves, cobra...

In vitro Multiplication of Aromatic and Medicinal Plants and Fungicide Activity

Aromatic and medicinal plants, widely used as folk medicine are, beyond fruits, vegetables grains and spices, the principal source of antioxidant compounds. Several studies demonstrated that antioxidants have also antifungal activity (Jayashree & Subramanyam, 2000; Rasooli & Abyaneh, 2004). More and more, humanity try to replace synthetic metabolites by natural metabolites. Therefore, studies in aromatic and me...

Mycobacterium avium subsp. paratuberculosis infection in slaughtered domestic p...

Herein, we report the occurrence of Mycobacterium avium subsp. paratuberculosis (Map), in four domestic pigs slaughtered for consumption that revealed compatible lesions of Mycobacterium spp. Infection in submaxillary and in mesenteric lymph nodes during the post mortem examination was observed. Histopathologic evaluation revealed granulomatous lesions mostly consisted by central necrosis, associated with infla...

A histoquímica no diagnóstico de micobacterioses em órgãos de mamíferos silvestres

O diagnóstico histoquímico de micobacterioses, através da visualização de bacilos álcool-ácido resistentes (BAAR), em esfregaços corados mediante a técnica de Ziehl-Neelsen, a partir de amostras de tecidos, é considerada como uma boa técnica de diagnóstico presuntivo. Neste estudo pretendeu-se avaliar a frequência de visualização de BAAR em rim e gânglios linfáticos mesentéricos com lesões granulomatosas em vea...

Comparative evaluation of PCR in Ziehl-Neelsen stained smears and PCR in tissue...

Thirty 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...
