Resumo: Foi realizado um levantamento soroepidemiológico da leptospirose em caprinos da microrregião do Seridó Oriental, Estado do Rio Grande do Norte, com o objetivo de determinar a prevalência de anticorpos anti-Leptospira spp. e identificar fatores de risco associados à infecção. Foram colhidas amostras de soro sanguíneo de 366 cabras em idade reprodutiva de 12 rebanhos. Para o diagnóstico sorológico da infecção por Leptospira spp., foi utilizada a Soroaglutinação Microscópica (SAM) com uma coleção de 24 sorovares de leptospiras vivas como antígenos. Dos 366 caprinos investigados, 53 foram soropositivos para pelo menos um sorovar de Leptospira spp., resultando em uma soroprevalência 14,5% (IC 95% = 11,0 - 18,5). O sorovar mais frequente foi o Autumnalis (73,6% das reações positivas). Não foram encontradas variáveis associadas à ocorrência de leptospirose (p >; 0,05).

Abstract: A sero-epidemiological survey was conducted to determine the prevalence of anti-Leptospira spp. antibodies as well as to identify risk factors associated with infection in goats of the Seridó Oriental microregion, Rio Grande do Norte State, Northeastern Brazil. Serum samples from 366 adult goats from 12 herds were collected. For serological diagnosis of Leptospira spp. infection, the microscopic agglutination test (MAT) was carried out using 24 live Leptospira spp. serovars as antigens. Out of the 366 investigated goats, 53 were seropositive for at least one Leptospira spp. serovar, resulting in a seroprevalence of 14.5% (95% CI = 11.0% ? 18.5%). The most prevalent serovar was the Autumnalis (73.6% of the positive reactions). There were no variables associated with leptospirosis occurrence (p > 0.05).

Anthracnose disease of common bean (Phaseolus vulgaris), caused by Colletotrichum lindemuthianum, is responsible for extensive yield losses worldwide. This pathogen is known to vary greatly in its pathogenicity. Control strategies include chemical control and, mainly, the development of resistant cultivars, taking into account the population structure of C. lindemuthianum. The objective of this study was to investigate the pathogenic and genetic diversity and population structure among C. lindemuthianum isolates collected in Minas Gerais state, Brazil. When these isolates were inoculated on 12 differential cultivars, a total of 10 races were identified within a series of 48 isolates collected in Minas Gerais, Brazil. Races 65, 81 and 73 were the most frequent races and occurred in most of the regions. This study also detected race 337, which had not been reported previously in the literature. Random amplified polymorphic DNA (RAPD) analysis performed on the same 48 isolates revealed great genetic diversity, clustering the series into five groups at a maximum similarity value of 89.6%. There was no clear relationship between the loci sampled by RAPD markers and the pathogenic characterization. Analysis of molecular variance showed that 96.06% of the variability was contained within regions and 3.94% among regions, indicating a high exchange of genetic material among the regions of the State. Most of the variability was detected within races (75.24%). The pathogenicity and RAPD assays corroborated the broad genetic diversity of the pathogen and the results have been useful in breeding for resistance to anthracnose.
