1. In vitro growth-inhibitory effect of Brazilian plants extracts against Paenibacillus larvae and toxicity in bees
Loque americana é uma grave doença de propagação mundial em abelhas causada pelo Paenibacillus larvae. Extratos de plantas são conhecidos por diminuir ou inibir o crescimento dessa bactéria. O objetivo deste estudo foi avaliar a atividade antimicrobiana dos extratos de Calendula. officinalis, Cariniana domestica, e Nasturtium officinale contra o P. lar

2. Isolamento de esporos de Paenibacillus larvae subsp. larvae no Brasil.
Este trabalho objetivou detectar presença de esporos de Paenibacillus larvae subsp. larvae em produtos de um entreposto do interior do Estado do Rio Grande do Sul, a identificação de possíveis fontes de contaminação e a avaliação da possibilidade da transferência de esporos para colméias de apiários adjacentes a partir de produtos importados conta

3. Caracterização de peptídeos antimicrobianos de Bacillus amyloliquefaciens com atividade antibacteriana, antifúngica e amebicida
Bacteriocinas são peptídeos pequenos sintetizados por bactérias que possuem propriedades antimicrobianas. O presente estudo teve por objetivos identificar e caracterizar uma bacteriocina produzida por Bacillus amyloliquefaciens LBM 5006, isolado de solo da Mata Atlântica, Santa Catarina, Brasil. A produção da substância antimicrobiana tem início na f

4. Efeitos nas características físico-químicas, microbiológicas e sensoriais em amostras de mel de abelhas submetidas à radiação gama / Effects on physicochemical, microbiological and sensory characteristics of honey bee samples submitted to gamma radiation
Honey production in Brazil has increased considerably and gaining proeminence on the international market, as a result many demands have become part of the productive honey chain. In addition to the analyses provided for the Brazilian legislation, international market demand products that meet the most stringent quality standards. Honey has interesting chara

5. Mecanismos de defesa comportamental e anatômico contra doenças e ectoparasitas em abelhas africanizadas (Apis mellifera) / Behavioural and anatomic defense mechanisms against diseases and ectoparasites in Africanized honey bees (Apis mellifera)
This study was conducted to select Apis mellifera colonies for diseases and ectoparasites tolerance and to investigate characters of proventriculus that confer protection against pathogens. Colonies in the region of Viçosa, Minas Gerais, Brazil, were evaluated for hygienic behavior using pin-killer brood and levels of infestation by Varroa destructor on bro

6. DESENVOLVIMENTO DE METODOLOGIA PARA ANÁLISE DE SULFONAMIDAS EM MEL UTILIZANDO CROMATOGRAFIA LÍQUIDA E DETECÇÃO POR ARRANJO DE DIODOS / DEVELOPMENT OF METHODOLOGY FOR ANALYSIS SULFONAMIDES IN HONEY USING LIQUID CHROMATOGRAPHY AND DETECTION DIODE ARRAY
Honey is a natural substance produced by bees and by your nature it is considered a healthy product. Presence of additives and/or preserve agents is not permitted. On apiculture, sulfonamydes are largely used on prevention and control of beehive disease, such as American foulbrood caused by Paenibacillus larvae. A consequence of this practice is the presence

8. Differentiation of Paenibacillus larvae subsp. larvae, the Cause of American Foulbrood of Honeybees, by Using PCR and Restriction Fragment Analysis of Genes Encoding 16S rRNA
A rapid procedure for the identification of Paenibacillus larvae subsp. larvae, the causal agent of American foulbrood (AFB) disease of honeybees (Apis mellifera L.), based on PCR and restriction fragment analysis of the 16S rRNA genes (rDNA) is described. Eighty-six bacterial strains belonging to 39 species of the genera Paenibacillus, Bacillus, Brevibacill

9. Development and Evaluation of PCR Assays for the Detection of Paenibacillus larvae in Honey Samples: Comparison with Isolation and Biochemical Characterization
PCR assays were developed for the direct detection of Paenibacillus larvae in honey samples and compared with isolation and biochemical characterization procedures. Different primer pairs, designed from the 16S rRNA and the metalloproteinase precursor gene regions, and different DNA extraction methods were tested and compared. The sensitivity of the reaction

10. A PCR Detection Method for Rapid Identification of Paenibacillus larvae
American foulbrood is a disease of larval honeybees (Apis mellifera) caused by the bacterium Paenibacillus larvae. Over the years attempts have been made to develop a selective medium for the detection of P. larvae spores from honey samples. The most successful of these is a semiselective medium containing nalidixic acid and pipermedic acid. Although this me

11. Genetic and Biochemical Diversity among Isolates of Paenibacillus alvei Cultured from Australian Honeybee (Apis mellifera) Colonies
Twenty-five unique CfoI-generated whole-cell DNA profiles were identified in a study of 30 Paenibacillus alvei isolates cultured from honey and diseased larvae collected from honeybee (Apis mellifera) colonies in geographically diverse areas in Australia. The fingerprint patterns were highly variable and readily discernible from one another, which highlighte
