The purpose of this study was to investigate the antimicrobial effect of a Punica granatum Linn (pomegranate) phytotherapeutic gel and miconazole (Daktarin oral gel) against three standard streptococci strains (mutans ATCC 25175, sanguis ATCC 10577 and mitis ATCC 9811), S. mutans clinically isolated and Candida albicans either alone or in association. The effect of minimum inhibitory concentrations of the gels on the adherence of these microorganisms to glass was assessed in the presence of 5% sucrose, using increasing and doubled concentrations of the diluted solution of the gels ranging from 1:1 to 1:1024. The minimum inhibitory concentrations of adherence of Punica granatum L. gel against the test organisms were: 1:16 for S. mutans (ATCC), S. mutans (CI) and S. sanguis; 1:128 for S. mitis and 1:64 for C. albicans. The minimum inhibitory concentrations of adherence of miconazole against the same organisms were: 1:512, 1:64, 1:4, 1:128 and 1:16, respectively. In experiments with three and four associated microorganisms, the Punica granatum L. gel had greater efficiency in inhibiting microbial adherence than the miconazole. The results of this study suggest that this phytotherapeutic agent might be used in the control of adherence of different microorganisms in the oral cavity.
Abstract.A gynandromorph specimen of Eulaema atleticana Nemésio, the first registered in Eulaema, is described. The E. atleticana gynandromorph was captured using an eucalyptol scent trap, in the Mata do Buraquinho Reserve, an Atlantic Forest fragment. The study site has 550 ha and is located in the urban area of the Municipality of João Pessoa, State of Paraíba, Northeast Brazil. The specimen presents antero-posterior and bilateral asymmetry. The head presents only male morphological characteristics. The mesosoma is composed by male and female structures, with male fore and middle legs. The right hind tibia shows a mosaic of male and female characters, with rudiments of the tibial organ and a corbicula. The metasoma presents only female characters.
Current global change substantially threatens pollinators, which directly impacts the pollination services underpinning the stability, structure and functioning of ecosystems. Amongst these threats, many synergistic drivers, such as habitat destruction and fragmentation, increasing use of agrochemicals, decreasing resource diversity, as well as climate change, are known to affect wild and managed bees. Therefore, reliable indicators for pollinator sensitivity to such threats are needed. Biological traits, such as phenotype (e.g. shape, size and asymmetry) and storage reserves (e.g. fat body size), are important pollinator traits linked to reproductive success, immunity, resilience and foraging efficiency and, therefore, could serve as valuable markers of bee health and pollination service potential. This data paper contains an extensive dataset of wing morphology and fat body content for the European honeybee (Apis mellifera) and the buff-tailed bumblebee (Bombus terrestris) sampled at 128 sites across eight European countries in landscape gradients dominated by two major bee-pollinated crops (apple and oilseed rape), before and after focal crop bloom and potential pesticide exposure. The dataset also includes environmental metrics of each sampling site, namely landscape structure and pesticide use. The data offer the opportunity to test whether variation in the phenotype and fat bodies of bees is structured by environmental factors and drivers of global change. Overall, the dataset provides valuable information to identify which environmental threats predominantly contribute to the modification of these traits.
Purpose: To assess the number of Streptococcus mutans in saliva of patients with denture stomatitis before and after antifungal therapy.Methods: After examining 93 patients, 47 were selected for fungal test. Then, from this sample, thirty patients were selected: 15 with positive and 15 with negative diagnosis for candidiasis that were evaluated for S. mutans counting, salivary flow and buffer capacity evaluation. Oral hygiene and prosthesis hygiene, period using prosthesis, lesion type and salivary data were related with clinical laboratorial characteristics of the patients with Candida.Results: The most frequent lesions were type I (43.5%) and II (53.5%). The amount of S. mutans was six times higher in patients with candidiasis and it was associated with low salivary flow and poor oral hygiene. After therapy, a reduction of S. mutans was verified particularly in patients with normal salivary flow. The values ranged from 0.01 to 3.88 x 10 4 cfu/mL.Conclusion: The data suggest that Streptococcus spp collaborates with Candida spp in the etiology and pathogenesis of denture stomatitis. The use of oral antimicrobial agents may provide a beneficial effect for denture stomatitis patients that are under antifungal therapy and that have poor oral hygiene and unfavorable salivary parameters.Key words: Dental prosthesis; antifungal agents; Candida; Streptococcus mutans ResumoObjetivo: Verificar o número de Streptococcus mutans em saliva de pacientes com estomatite protética antes e após a terapia antifúngica.Metodologia: Após exame clínico de 93 pacientes, 47 foram selecionados para exame micológico e desta amostra foram selecionados trinta pacientes: 15 com diagnóstico positivo e 15 com diagnóstico negativo de candidose foram avaliados para contagem de S. mutans, determinação de fluxo salivar e capacidade tampão. Higiene bucal e da prótese, tempo de confecção, tipo de lesão e dados salivares foram relacionados com características clínicas e laboratoriais de Candida.Resultados: As lesões frequentes foram dos tipos I (43,5%) e II (53,5%). A quantidade de S. mutans foi seis vezes maior em pacientes com candidose e foi associada com baixo fluxo salivar e higiene oral deficiente. Após a terapia, a redução de S. mutans foi verificada particularmente em pacientes com fluxo salivar normal. Os valores variaram de 0,01 a 3,88 UFC/ml x 10 4 .Conclusão: Os dados sugerem que os Streptococcus colaboram com Candida spp na etiopatogenia da estomatite protética. O uso de agentes antimicrobianos orais pode propiciar efeito benéfico para pacientes com estomatite protética submetidos à terapia antifúngica e que apresentam higiene oral deficiente e parâmetros salivares desfavoráveis.
