| O trabalho procurou apresentar de forma simples e objetiva os princípios e fundamentos do melhoramento genético, ao mesmo tempo que descreve a trajetória histórica do melhoramento animal no Brasil enfatizando sua importância e contribuições. As discussões foram apresentadas com o intuito de possibilitar melhor entendimento do papel fundamental que a genética representa, principalmente, nesse momento de grandes transformações que estão constantemente a exigir, como resultados das iniciativas tomadas em quaisquer segmentos das diversas cadeias produtivas que envolvem animais domésticos, mais acuracia e eficiência. Para isso, conceitos básicos como seleção e cruzamento são apresentados, bem como introduzem-se discussões acerca de variabilidade genética, valor... |

| ABSTRACT: Occurrence and antimicrobial resistance profiles of Campylobacter jejuni and C. coli strains isolated from fecal samples of dogs, pigs, cows and hens in southern Ecuador were studied. Of the 250 samples studied, 84 (33.6%) were Campylobacter positive, with C. jejuni being more frequent (78.6%) than C. coli (21.4%), with the exception of porcine samples, from which C. coli was the only species isolated. Multidrug resistance was reported in 10 Campylobacter strains (11.9%), four C. jejuni and six C. coli, and was always associated with nalidixic acid and ciprofloxacin resistance. All of the amoxicillin-resistant strains were susceptible to amoxicillin-clavulanic acid and were therefore beta-lactamase producers. However, one strain of C. jejuni... |

| Background: Corsica is a mountainous French island in the north-western Mediterranean presenting a large diversity of natural environments where many interactions between domestic animals and wild fauna occur. Despite a favourable context for ticks and tick-borne diseases (TBDs), the tick fauna of Corsica has not systematically been investigated. Methods: For one year (May 2014-May 2015), a survey of ticks infesting cattle was performed in the three Corsican cattle slaughterhouses. Two of these were visited monthly and one quarterly; the ticks were manually collected, just after flaying. Ticks were identified on their morphology; when necessary, some specimens were also molecularly identified by sequencing mitochondrial cox1 (cytochrome c oxidase subunit... |
