“…This act can cause antibiotics resistance when the rules about dose and applications are neglected. Gomes et al (2016) and Saeki et al (2011) found positive results in which the alcoholic extract of propolis was effective against Staphylococcus aureus from of animals with mastitis, presenting a halo between 6 and 18 mm, suggesting as an alternative to use of commercial antibiotics. In addition, the higher production in summer increases the susceptibility of animals to the entry of microorganisms, due to the humidity and high temperature conditions that favor the development of pathogens, combined with increased contact with animals.…”

Mastitis is a disease in dairy cattle that damage the milk chain. It was aimed identify the major causative agents of bovine mastitis in small dairy farms by producing an antibiogram and analysis of milk quality. Methods: During the summer, 280 dairy cows were examined on a farm located in Camapuã, MS, Brazil. The farm had a concrete milking facility and used cleaning and disinfection of the udder before and after milking to control mastitis. For assess microbial resistance, two samples of milk per cow were collected biweekly between January and March. The antibiotics sulfazotrim (25 μg), penicillin (10 μg), streptomycin (10 μg), vancomycin (30 μg), chloramphenicol (30 μg), tetracycline (30 μg), amoxicillin (10 μg), and gentamycin (10 μg) were used. Results: A total of 17.14% of the animals were positive for the California Mastitis Test (CMT). The identification of the pathogens revealed that Staphylococcus aureus accounted for 41.65% of the isolated organisms and Escherichia coli for 37.5%. Our results showed only sulfazotrim and chloramphenicol had effective results for both Gram-negative and Gram-positive bacteria. The isolated strains presented high resistance to the other tested antibiotics. Conclusions: sulfazotrim (25 μg) and chloramphenicol (30 μg) can be used to disinfect the udder of dairy cows.

Resumo: A Própolis de abelhas africanizadas (Apis mellifera L.) é um produto da colmeia, elaborado a partir de exsudações de resinas que as abelhas recolhem de determinadas plantas. A composição química da própolis é complexa e relacionada à diversidade vegetal encontrada em torno da colmeia. Estudos recentes demonstram que a própolis possui uma série de propriedades biológicas, essas propriedades têm feito da própolis uma importante matéria-prima para as indústrias farmacêutica, alimentícia e de cosméticos. O estudo dessas propriedades é, portanto, necessário, a fim de se obter um produto com alto padrão de qualidade e valor agregado. Este trabalho tem como objetivo avaliar o efeito de sete extratos alcoólicos da própolis (EAP) apícola Potiguar no desenvolvimento de quatro microrganismos de importância veterinária. As colmeias habitadas com enxames de abelhas africanizadas (Apis mellifera L.) selecionados para coleta da própolis estavam organizadas em apiários, distribuídos em região de vegetação distinta no estado do Rio Grande do Norte, Brasil. As coletas de material no campo ocorreram no período dos meses de outubro a dezembro de 2013, a obtenção dos extratos e os ensaios do potencial antibiótico ocorreram durante o ano de 2014. Foi identificado que os EAP 1, 6 e 7 foram ativos nos quatro microrganismos testados, e os EAP 3 e 4 não demonstraram-se ativos para nenhum microrganismo. Os resultados encontrados evidenciam a superioridade da própolis vermelha do mangue Potiguar quando comparados aos resultados citados em outros estudos para os mesmos microrganismos. Palavras Chave: Extrato Alcoólico de Própolis; Enterobacter aerogenes; Escherichia coli; Staphylococcus aureus; Salmonella spp.Abstract: Propolis Africanized bees (Apis mellifera L.) is a product of the bee hive, elaborated based on exudates resins that bees collect from certain plants. The chemical composition of propolis is complex and related to plant diversity found around the bee hive. Recent studies have shown that propolis has a number of biological properties, these properties have made from propolis an important raw material for the pharmaceutical, food and cosmetic industries. The study of the properties is therefore necessary in order to obtain a product with a high standard of quality and value. This study aims to evaluate seven different alcoholic extracts of propolis (AEP), of Potiguar honey bees, in the development of four microorganisms of great veterinary importance. The bee hives inhabited by swarms of Africanized bees (Apis mellifera L.) selected for the collection of propolis were organized in apiary distributed in different vegetation region in the state of Rio Grande do Norte, Brazil. The material collected in the field occurred in the period from October to December 2013, obtaining the extracts and antibiotic potential of the trials took place during the year 2014. It was identified that the EAP 1, 6 and 7 were active in all four tested microorganisms, and the EAP 3 and 4 are not demonstrated to be active for any microorganism. T...

Nos comentários do painel sensorial observou-se que os extratos foram detectados sensorialmente. Conclusões -Nas concentrações aplicadas nos pães integrais, os extratos não alcançaram todas as características de conservantes naturais para serem considerados substitutos de conservantes químicos. O pão com própolis apresentou maior tempo de armazenamento aceitável do que o pão com mix de OE, corroborando com os resultados dos testes realizados nos extratos e indicando maior potencial antioxidante e antimicrobiano para o extrato de própolis. As três amostras de pães obtiveram boa aceitação sensorial e com potencial para aquisição.Descritores: Óleos essenciais; Própolis; Antimicrobianos; Aditivos alimentares; Pão.MOTA, E. B. F. Performance of natural extracts with antimicrobial effect on the conservation of whole-grain breads. ABSTRACTIntroduction -Essential oils (OE) and propolis have antimicrobial properties, which generate interest in the production of food to replace chemical preservatives, which can cause damage to the body with its frequent exposure. Bread, a food of high consumption in Brazil, generally has chemical preservatives among its ingredients when it is industrialized, even if it is of the integral type. Replacing these additives with natural preservatives becomes a strategy for health promotion. Purpose -Evaluate the preservative action of natural extracts in whole grains. Methods -A mix of OE (thyme, oregano and basil) and an alcoholic extract of propolis were used, which were analyzed for antioxidant and antibacterial activities. These extracts were added to the whole loaves formulation, being macroscopically verified for the appearance of signs of deterioration in two periods of the year and physico-chemically analyzed for pH, water activity (aw), color and instrumental texture during the first , the fourth and the seventh day of storage. A sensorial acceptance test was performed by hedonic scale and by intention of purchase test. Data were analyzed through analysis of variance (ANOVA) and Tukey test. Results -Antioxidant and antibacterial tests revealed lower values of EC50 (amount of antioxidant needed to decrease the concentration of the radical by 50%) and MIC50 (lower concentration of an antimicrobial agent that prevents visible growth of a microorganism by 50%) for propolis. In the period of the year with lower average temperature, the control loaves and with OE mix presented visual deteriorations in the seventh day of storage, whereas in this day no deteriorations in the bread with propolis were observed. The pH and aw measurements of the breads met the standard for these products. The color of the breads presented L * color intervals from 57.11 to 63.50, a * from 0.20 to 1.79 and b * from 22.83 to 25.50 and the maximum shear force variation of 9.1 N to 50.2 N. For the sensorial analysis 103 individuals participated with frequent consumption of breads. The hedonic scale test revealed mean scores ranging from "slightly liked" to "moderately liked". The IA indicated that the control bread was...
