| 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... |

| ABSTRACT: Pseudorabies (PR) is a highly contagious viral disease of great animal health and economic importance in swine industry. The aim of this study was to evaluate different genomic regions, real-time PCR chemistries and equipment for the molecular diagnosis of PR. Eight primer pairs targeting four genes (gB, gC, gE, gD), three different qPCR chemistries (SybrGreen, hydrolysis probes and plexor) and two equipment (ABI7500, Rotorgene 3000) were evaluated. Oligonucleotides targeting gB using hydrolysis probes showed the best performance after evaluating efficiency (99%), the detection limit (10-1.5 TCID50 mL-1) and diagnostic sensitivity and; therefore, those primers were selected for performance verification factors such as repeatability,... |
