On certain bacteria from the air of New York City.Dyar, Harrison G. (Harrison Gray), 1866-1929 January 1895 (has links)
It was suggested to me by Dr. T. Mitchell Prudden that a promising field for research existed in determining the identity of the bacterial commonly occurring in the air of New York.
Very early in the investigation a practical difficulty in the way of determining species became apparent. It was found, however that the determinations of the species were not always authentic, as seen by the fact that when planted on the standard media many of them contradicted their published characters.

"Aeromicrobiota do ambiente cirúrgico: princípios e peculiaridades da climatização artificial" / "Air microbiology of surgical environment: principles and singularities of artificial climate"Paula, Juliana Ferreira Lima de 18 December 2003 (has links)
O presente estudo tem como meta primordial investigar a temática aeromicrobiota do ambiente hospitalar, especialmente, do centro cirúrgico com vistas a enfocar contaminação biológica por conseqüência da climatização artificial, bem como fornecer informações técnicas aos profissionais afins. Assim, estabeleceu-se como objetivos específicos: quantificar e categorizar a produção do conhecimento científico nacional e internacional relacionada a aeromicrobiota do ambiente hospitalar e testar um método de avaliação microbiológica do ar do ambiente cirúrgico considerando os parâmetros biológicos da legislação nacional, e o binômio custo/benefício. As autoras evidenciaram na literatura investigada que a avaliação microbiológica do ar é expressiva nos estudos, e, quanto ao tipo de microrganismo o Aspergillus sp e o Staphylococcus sp foram os mais mencionados. Em seguida, apontam a problemática da aerocontaminação biológica e discutem as alternativas de controle da qualidade do ar. Com relação a avaliação microbiólogica do ar por meio de placas Petrifilm AC Aerobic Count (3M, St Paul, MN, USA) em diferentes salas cirúrgicas ortopédicas observaram que o número de amostras positivas da entrada foi menor que na saída do ar: sala1, 0,0 na entrada e 55,6 na saída; sala 2, 40 e 83,3 e na 14 de 20,0 e 60,0%, respectivamente. Quanto ao nível de contaminação (ufc) foi expressiva apenas duas amostras da sala 2. No computo geral, os gêneros isolados foram Bacillus, Micrococcus, Actinomyces. Vale acrescentar que fungos não foram detectados. Esses resultados apontam para a eficiência do sistema de climatização. Alertam para a necessidade de uma pluralidade de ações estruturadas na multidisciplinaridade, bem como, na aplicação crítica das Resoluções e Portarias vigentes. / This study has as main goal to investigate about air microbiology of hospital environment, specially, surgical center, aiming to focus biological contamination due to artificial climate, as well as to provide technical information to professionals. So, the specific goals of this study are to quantify and classify national and international production of scientific knowledge related to air microbiology of hospital environment and test an evaluation method of air contamination, taking into account biological parameters of Brazilian legislation, and the relationship between cost and benefit. The authors have pointed out into scientific literature that air microbiological evaluation is expressive and the microorganisms Aspergillus and Staphylococcus were mentioned mostly. Next, they show the problems concerning biological contamination by air and discuss about alternative ways of controlling air quality. Regarding the microbiological air evaluation applying Petrifilm AC Aerobic Count plates (3M, St Paul, MN, USA) in different orthopedic surgical rooms, the results reveal a greater number of positive samples collected at the air exit compared to those at the air entry: room 1 got 0.0 at entry and 55.6 at exit; room 2, 40 and 83.3 and room 14, 20.0 and 60.0%, respectively. The contamination level (ufc) was expressive only on two samples of room number 2. The final analysis shows that the isolated genus were Bacillus, Micrococcus and Actinomyces and fungus were not detected. These results point out the efficiency of the air conditioning system and strengthen to the need of a plurality of structured actions in the multidisciplinary field, as well as in the appliance of Brazilian legislation.

The authors have pointed out into scientific literature that air microbiological evaluation is expressive and the microorganisms Aspergillus and Staphylococcus were mentioned mostly. Next, they show the problems concerning biological contamination by air and discuss about alternative ways of controlling air quality. Regarding the microbiological air evaluation applying Petrifilm AC Aerobic Count plates (3M, St Paul, MN, USA) in different orthopedic surgical rooms, the results reveal a greater number of positive samples collected at the air exit compared to those at the air entry: room 1 got 0.0 at entry and 55.6 at exit; room 2, 40 and 83.3 and room 14, 20.0 and 60.0%, respectively. The contamination level (ufc) was expressive only on two samples of room number 2. The final analysis shows that the isolated genus were Bacillus, Micrococcus and Actinomyces and fungus were not detected. These results point out the efficiency of the air conditioning system and strengthen to the need of a plurality of structured actions in the multidisciplinary field, as well as in the appliance of Brazilian legislation.
