| The prevalence of small ruminant lentivirus (SRL) infection was evaluated in goats and sheep in two counties of Pernambuco State, Brasil. Seriological examinations were performed from a total of 672 goats and 325 sheep, one year of age and older, at two abattoirs. Sera were analyzed by agar gel immunodiffusion using Maedi-Visna K-1514 antigens. There were 42 reactive samples (95% confidence interval 3.6% to 4.9%) in both slaughter houses. In São Lourenço da Mata county, 3.2% and 4.0% of goat and sheep sera were responsive, whereas in Paulista county, 5.1% of goat samples and 8.2% of sheep were reactive. Thus, the prevalence of small ruminant lentivirus was low in goats and sheep sampled from the region. |

| An epidemiological model is described that closely mimicked results of a published serological study of natural transmission of Maedi-Visna virus in a low ground flock of sheep. We adjusted parameters in the model from this baseline to explore the possible implications for the control of Maedi-Visna virus in typical British flocks. On closed hill farms, low probability of effective contact was most critical for control. In open low ground flocks, purchasing accredited replacements eliminated disease spread, otherwise flock size was the most important factor governing flock prevalence. Results highlighted the need for more epidemiological information about Maedi-Visna, particularly whether hill farms act as a hidden reservoir of virus or reduce the impact... |

| Objetivou-se realizar uma avaliação prospectiva de relevantes enfermidades infecciosas de ovinos e caprinos ligados à agroindústria da carne na Bacia do Jacuípe, BA. Para tanto, foi realizado o diagnóstico sorológico de sete doenças: Agalaxia contagiosa (AC); Artrite-encefalite caprina (CAE); Brucelose ovina; Clamidiose; Maedi-visna; Paratuberculose; Toxoplasmose. |
