Objective: the aim of the present study was to obtain data on the microbiota of human colostrum, and to correlate it with a possible source of probiotics transferred from mother to infant during breastfeeding. Methods: 70 samples of milked human colostrum were analyzed as to the presence of mesophylic, thermoduric, psychrotrophic, proteolytic, proteolytic-psychrotrophic, lipolytic microorganisms, molds and yeasts, Staphylococcus aureus, total coliforms, fecal coliforms, Group D Streptococcus species and lactic acid bacteria. Results: the microbiological analyses revealed several classical groups of microorganisms: mesophylic (68.6%); thermoduric (38.6%); psychrotrophic (8.6%); proteolytic (15.7%); proteolyticpsychrotrophic (1.4%); lipolytic (4.3%); molds and yeasts (11.4%); Staphylococcus aureus (44.3%); total coliforms (7.2%); and lactic acid bacteria (37.2%), thus characterizing a diversified microbiota. Thermoduric-psychrotrophic microorganisms, fecal coliforms and Group D Strept...

Bacterial or fungal infections might produce a clinical feature of mastitis, which is one of the main causes of precocious breast-feeding discontinuity. In addition, when the potentially pathogenic microorganisms as yeast of Candida genera were in high counting in the intestine, might cause dysbiosis. This study aimed detecting and identifying fungi in human milk and anatomical sites of breast-feeding women and infants who were enrolled at Human Milk Bank of the Institute Fernandes Figueira. The virulence of the yeast isolates was evaluated by means of proteolytic activity tests. Eight-one percent of 64 analyzed samples showed positive results to fungi, with a highest prevalence of Candida albicans (73%) followed by C. parapsilosis complex (15.4%). Similar profiles were found in samples of milk, of breasts and of infants mouth cavity, suggesting a correlation between breast-feeding mothers and infants cutaneous infections with the ingested milk. The virulence of the isolated Candida...

The first scientific studies on probiotics date back to the beginning of the century with the work of Metchnikoff at the Pasteur Institute. This investigator postulated that hosts could benefit from fermented milk in the sense that it antagonizes bacteria that affect the intestines(1-3). The initial hypothesis posited that bacterial strains with more efficient mucosal adherence would be more beneficial for their hosts(2).

The authors characterized the genera of mycelial fungi found in samples of expressed human milk received through home collection by the Human Milk Bank of the Instituto Fernandes Figueira in Rio de Janeiro. A total of 821 samples of expressed human milk were taken randomly from bottles collected at home by the milk donors themselves and were investigated for molds, yeasts, and mesophilic microorganisms. The analyses showed the occurrence of molds and yeasts in 43 (5.2%) of the samples, with counts reaching 103CFU/ml. Some 48 strains of mycelial fungi were identified by standard laboratory techniques, including: Aspergillus Niger group (6.3%), Aspergillus sp. (4.2%), Paecilomyces sp. (12.6%), Penicillium sp. (60.4%), Rhizopus sp. (2.0%), and Syncephalastrum sp. (14.5%). The authors discuss the importance of donor hands' asepsis prior to collecting human milk.

To contribute to the creation of a new theoretical synthesis about the relationship between the biological and social dimensions of breastfeeding, categorizing it as a nature-nurture hybrid. The methodological approach of the present article was based on the qualitative health research frame, and data were analyzed on the basis of dialectic-hermeneutic principles. Primary sources, comprising historical documents, books, scientific articles and medical theses written in the 19th and 20th centuries were analyzed. Depending on the moment in history and on the expectations that surround the act of breastfeeding, the aspects related to nature and nurture, i.e., to biology and society, sometimes separate out and sometimes intermingle. A comprehensive approach to breastfeeding makes possible to see that it had to be considered instinctive, natural and biological in order to be assimilated as a cultural habit, and thus, it is not open to any kind of questioning. On other occasions, particularly in the course of the past decade, there has been a steady tendency to supplant traditional biological reductionism, which yielded cultural interpretations that do not reduce the human being to the status of a mammal like any other. Under this point of view, breastfeeding, in addition to being biologically determined, is socially conditioned, and thus constitutes an act embedded in ideologies and determinants resulting from the concrete conditions of life. In real life, however, a process apparently so natural, so loaded with affection and emotion is, in fact, affected by the most aggressive market interests, very often presented as scientific knowledge and decked out as health provisions. Breastfeeding focused as a nature-culture hybrid symbolizes the theoretical and methodological changes in the field, especially in the late 1990s. These changes reflect a renewed appreciation of biology and a more in-depth approach to interdisciplinary processes.

In many respects Web 2.0 and Knowledge Management (KM) are strongly related to each other. From a KM perspective the Web 2.0 evolution can serve as a pool of ideas for new ways of knowledge sharing, knowledge organisation and for the development of new architectures of measurable knowledge management systems. KM projects are usually developed in a process-oriented, goal-driven environment, embedded in complex organisational structures, whereas typical Web 2.0 applications like del.icio.us, flickr or friendster are building "their own context". This paper will examine Tim O´Reilly's eight generic Web 2.0 design patterns in terms of their applicability for a measurable KM System in an Enterprise 2.0. Two use cases will be presented and it will be discussed which of the design patterns could be enriched by technologies from the semantic web which will be summarized as a concept named "Enterprise n+1".

A veiculação de microrganismos potencialmente patogênicos, resistentes aos antibióticos, por meio de leite humano ordenhado, pode ser um fator de risco potencial. Este estudo teve como objetivo contribuir para um melhor conhecimento dos coliformes isolados de leite humano ordenhado (LHO) e de seu perfil de resistência a antimicrobianos. Seguiu-se um delineamento inteiramente casualizado, utilizando 837 amostras de LHO, nas quais 71 (8,48%) estavam contaminadas com coliformes totais, cuja contagem em nenhuma das amostras ultrapassava 1,0x10³NMP/ml. A maioria dos microrganismos isolados (91,6%) pertencia a apenas duas espécies, Enterobacter cloacae e Klebsiella pneumoniae. As 71 cepas de coliformes apresentavam resistência a pelo menos um dos antimicrobianos testados. Conclui-se que o LHO coletado e armazenado sob condições higiênico-sanitárias insatisfatórias, pode apresentar coliformes, que desgastam os fatores de proteção, reduzem o valor nutricional e a qualidade do produto.

To study the microbiology of banana peel being sold in the city of Rio de Janeiro, in an attempt to determine the possibility that the peel may represent a source of infection for women who use it to treat nipple fissures. The following microorganisms were studied in 20 banana peel samples: mesophiles, total coliforms, fecal coliforms, Pseudomonas aeruginosa, lipolytic and proteolytic microorganisms, molds and yeasts, lactic bacteria, and coagulase-positive staphylococcus. The microbiological analyses revealed the occurrence of several typical groups of microorganisms, with the following distribution of positive results being detected in banana peel samples: mesophiles, 100%; total coliforms, 20%; coagulase-positive staphylococcus, 25%; molds and yeasts, 30%; proteolytic microorganisms, 70%; lipolytic microorganisms, 30%, and lactic bacteria, 95%. Fecal coliforms and Pseudomonas aeruginosa were not isolated. The results show the presence of potentially pathogenic microorganisms in l...

To compare an alternative method to the most probable number (MPN) test for the detection of total coliform present in manually expressed human milk. 343 samples of manually expressed human milk from flasks donated to the Human Milk Bank of Instituto Fernandes Figueira--IFF were sent to the Laboratory of Food Control of IFF. The samples were used for comparing both methods, i.e., the most probable number (MPN) method, as described in the "Standard methods for the examination of dairy products", and the alternative method. Coliforms were detected in 31.2% of the samples analyzed, with populations ranging from 3.0 x 10(0) to 1.1 x 10(4) total coliform MPN/mL. The comparison between classical and alternative methods showed similar results regarding the presence of coliform microorganisms in expressed human milk samples. The alternative method detected the presence of total coliform in all contaminated and in four noncontaminated samples according to the MNP method. The altern...

To characterize the genera of mycelial fungi detected in expressed human milk received at the human milk bank of Instituto Fernandes Figueira after home collection. We studied 821 expressed human milk samples randomly obtained from flasks filled by the donors at home. The possible presence of molds, yeasts and mesophilic microorganisms was investigated. A total of 48 strains of mycelial fungi were isolated from the human milk bank samples and identified through standard laboratory techniques. Microbiological analysis revealed the occurrence of molds and yeasts in 43 samples (5.2%), with counts reaching 10(3) CFU/ml. The following microorganisms were identified: Aspergillus niger group (6.3%), Aspergillus sp. (4.2%), Paecilomyces sp. (12.6%), Penicillium sp. (60.4%), Rhizopus sp. (2.0%), and Syncephalastrum sp. (14.5%). Four samples showed the presence of more than one mycelial fungus type. The presence of molds and yeasts in human milk manually expressed at home suggests that the hy...

The Brazilian National Network of Human Milk Banks (REDEBLH), with its headquarters in the Oswaldo Cruz Foundation in Rio de Janeiro, is experiencing rapid growth. The Network's activity has been acknowledged by the World Health Organization and received the Sasakawa Health Award in 2001 for best public health project. One of the main challenges is to ensure continuing development of competencies to respond to the needs arising from such growth. A new strategy is being pursued to deal with the Network's management issues. This article aims to develop a conceptual framework to contribute to the elaboration of a theoretical framework for new management strategies in the REDEBLH. Using such concepts, the aim is to draw on the typology of networks described in the specialized literature to identify the institutional profile of the REDEBLH. Based on the understanding that it is necessary to identify and understand the processes occurring within networks, and after which to consid...
