Polymerase chain reaction for the diagnosis of bovine genital campylobacteriosis

Abstract: RESUMO.-[Reação em cadeia da polimerase para o diagnóstico de campilobacteriose genital bovina.] Campilobacteriose genital bovina é uma doença venérea comum em bovinos. A prevalência desta doença pode ser subestimada na maioria das vezes pela natureza microaeróbica do agente etiológico, Campylobacter fetus subspecies venerealis. O propósito do presente estudo foi avaliar a utilização da reação de polimerase em cadeia (PCR) no diagnóstico de campilobacteriose genital em amostras obtidas de aspirado prepucial de… Show more

“…According to Leal et al (2012), the sensitivity and specificity of the tests used to diagnose this type of infection are the principal causes of variations in prevalence results. One way of minimizing these variations is to use a more sensitive technique, such as PCR, to confirm the results and/or identify the agent directly (Schulze et al 2006;Groff et al 2010). In addition, other factors such as the age of the animals (Pellegrin et al 1999 sanitary management of herds can also affect these differences (Mardones et al 2008;Rocha et al 2009;Mai et al 2013).…”

“…In order to confirm the results, positive samples were purified after amplification and bidirectional sequenced using the BigDyeTerminator v3.1 Cycle-Sequencing kit 4 , according to the manufacturer's instructions. Sequencing was performed by capillary electrophoretic separation in an ABI 3500 Genetic Analyzer sequencer 4 . Data were collected using Data Collection Software 4 and underwent quality inspection through SequencingAnalysis Software 4 .…”

“…A coleta das amostras de machos e fêmeas foi realizada por aspirado prepucial e cervical, utilizando bainha de inseminação artifi cial (IA) IMV (Instruments de Médecine Vétérinaire Tecnologies ® ) francesa estéril, conectada em seringa de 20 a 60mL, e nos fetos abortados nessa coleta foi efetuada com auxílio de agulha e seringa estéril de 60mL. As amostras foram acondicionadas em meio de transporte e enriquecimento (TEM) (LANDER, 1990) e remetidos em até 48 horas após a colheita em temperatura ambiente ao laboratório, onde foram incubadas a 37°C durante cinco dias, para posterior extração de DNA e PCR, de acordo com GROFF et al (2010).…”

“…As condições para a extração e amplifi cação de DNA seguiram as descrições de HUM et al (1997), com modifi cações realizadas por VARGAS et al (2003) e GROFF et al (2010. Os primers utilizados foram espécie específi cos, MG3F (5'-GGTAGCCGCAGCTGCTAAGAT-3') e MG4R (5'-TAGCTACAATAACGACAACT-3') com um amplicon de 750 pb (GROFF et al, 2010). Os produtos de amplifi cação da técnica de PCR foram verifi cados em gel de agarose 1,5%, corado com brometo de etídio e visualizado em transluminador de luz ultravioleta.…”
