| The fungus Drechslera avenae, the causal agent of Helminthosporium leaf spot on oats (Avena sativa), survives as mycelium in crop residues and in infected seeds. In trials carried out in the laboratory, ten methods were evaluated for their efficiency to detect D. avenae in oat seeds. In each experiment, groups of two or three methods were compared to a standard protocol, in which seeds were placed in Petri dishes containing the Reis selective medium and incubated at 25±2 °C for ten days. Data were submitted to analysis of variation and the means of the methods were compared using the Dunnett test at the 5% significance level. Overall, the highest levels of seed infection by D. avenae were observed on oat seeds plated in the osmotic, the oat-agar and the... |

| ABSTRACT: In order to detect and identify Campylobacter spp. in broiler chicken carcasses, and to compare detection methods, 43 chilled and 43 frozen carcasses were collected and analyzed. Three methodologies were evaluated: an automated Enzyme Linked Fluorescent Assay (ELFA) VIDAS®30, Polymerase Chain Reaction (PCR) and real-time PCR. Only four chilled carcasses (4.6%) were considered positive for Campylobacter spp. by VIDAS®30 and no sample was positive when the conventional PCR technique was used. However, real-time PCR showed a higher incidence of contamination by Campylobacter spp. in broiler carcasses, with 45 (52.3%) positive samples. C. jejuni was the species most frequently reported in the samples (88.8%). No differences in the frequencies of... |
