[Bergey's Manual of Systematic Bacteriology (second edition) Volume 5 and the study of Actinomycetes systematic in China].

Bergey's Manual of Systematic Bacteriology (hereinafter referred to as "Bergey's Manual") is the collection of academic views accepted by taxonomists in many countries. It has scientificity, unitarity and practicality. "Bergey's Manual" (special issue of Actinomycetes) divided into two parts (part A and part B) was published in May, 2012. Under the guidance and the organization of Michael Goodfellow et al., the great work has been completed successfully in May 2012. "Bergey's Manual" made a great modification on the systematic of Actinomycetes and formally set up the phylum of Actinobacteria, which encompasses 6 classes, 23 orders (include one order incertae sides), 53 families, 222 genera and about 3000 species. The taxonomic catalogue is Bacteria, phylum of Actinobacteria, under the phylum there are class, order, family, genera and species. "Bergey's Manual" collected a great deal of new taxa, which were published in IJSEM (International Journal of Systematic and Evolutionary Microbiology) by Chinese scientists. We need to indicate that due to its too rigorous, conservative writing purpose and long publication periods, "Bergey's Manual" fails to collect new research results using the molecular approaches of multilocus sequence analysis "MLSA", gene chip technology and genome technologies, which however will profoundly change the taxonomy of prokaryotes in the near future.

Stenotrophomonas maltophilia, bacilo gram negativo no fermentador aislados de muestras clínicas de pacientes pediátricos / Stenotrophomas maltophilia gram negativ rod isloted ferment with nosocomial of patients infants

Stenotrophomonas maltophilia (SMA) es un bacilo gram negativo no fermentador que causa infecciones en pacientes con defensas disminuidas y/o instrumentados. Se realizó un análisis retrospectivo de los aislamientos obtenidos en el año 2003 en el laboratorio de Bacteriología del Hospital de Niños Sor María Ludovica. Se obtuvieron 64 aislamientos de los cuales 36 fueron de origen respiratorio y 24 de hemocultivos. Tanto su resistencia a carbapenemes como su sensibilidad a TMS son orientadores para su diagnóstico microbiológico. Este perfil asociado a resistencia a otros antibióticos suele plantear problemas terapéuticos severos

Nomenclature of the subgenera Moraxella and Branhamella and of the nine species included in these subgenera and proposal to modify rule 34a of the Bacteriological Code (1990 Revision). Request for an opinion.

The subgenera Moraxella and Branhamella and the nine species included in these subgenera were inadvertently omitted from the Approved Lists of Bacterial Names and have never been revived according to Rule 28a of the Bacteriological Code (1990 Revision). The author requests that these names be revived and considered to be validly published in the 'Index of the bacterial and yeast nomenclatural changes published in the International Journal of Systematic Bacteriology since the 1980 Approved Lists of Bacterial Names (1 January 1980 to 1 January 1985)', which appears in the July 1985 issue of the International Journal of Systematic Bacteriology. Another problem is the status of the species included in the subgenera Moraxella and Branhamella because the Bacteriological Code (1990 Revision) does not envisage the status of a species transferred into a subgenus. The same is true for a species transferred into a subspecies. The author requests that such species be considered as new combinations and, according to this, proposes to modify Rule 34a of the Bacteriological Code (1990 Revision).

Nomenclatural type of orders: corrections necessary according to Rules 15 and 21a of the Bacteriological Code (1990 Revision), and designation of appropriate nomenclatural types of classes and subclasses. Request for an opinion.

An important aspect of the Bacteriological Code (1990 Revision) is the designation of nomenclatural types to the various taxonomic ranks to provide a suitable reference point for the unambiguous identification of the taxon. Although the nomenclatural type of the species is the designated strain, and the nomenclatural type of the genus is the type species, the nomenclatural type of both the family and the order is the 'genus on whose name the name of the relevant taxon is based'. However, in some cases a genus has not been designated as the nomenclatural type of an order. Twelve cases that are contrary to the Rules listed and appropriate corrections are proposed. In addition, several classes have been named for which no nomenclatural type has been designated; this brings into question whether they can be considered to have been validly published, as well as highlighting the fact that they would be/are illegitimate.

Estafilococos coagulasa negativa: distribución de especies, producción de limo (Slime) y susceptibilidad a los agentes antimicrobianos / Coagulase-negative staphylococci: species distribution, slime production and susceptibility to antimicrobial agents

Los Estafilococos Coagulasa Negativa (SCN), usuales contaminantes de los cultivos bacteriológicos, constituyen patógenos oportunistas importantes en individuos con dispositivos médicos. Esta propiedad de virulencia selectiva se asocia a su capacidad de adherencia y producción de limo (slime). En este trabajo se determina la distribución de especies, patrones de susceptibilidad a los agentes antimicrobianos y capacidad de adherencia de 117 cepas de SCN aisladas de muestras clínicas. S.epidermidis resulta la especie predominante, seguida por S.haemolyticus y S.hominis. S.saprophyticus se aisla únicamente de urocultivos. Se detecta una alta resistencia a la mayoría de los antibióticos, principalmente penicilina (78,6 por ciento), oxacilina (37,6 por ciento), eritromicina (38,4 por ciento) y trimetroprim/sulfametoxazol (33,3 por ciento). Una proporción importante de las cepas son multirresistentes (70 por ciento). La multiresistencia es expresada principalmente por las cepas resistentes a oxacilina. No se detecta resistencia a vancomicina. El 44,4 por ciento de los aislamientos son adherentes, entre los cuales predomina S.epidermis, principalmente las cepas provenientes de hemocultivos. La capacidad de adherencia se encuentra altamente asociada a la especie de SCN, pero no guarda relación con la resistencia a múltiples antibióticos. Las cepas estudiadas muestran un importante potencial patogénico, por lo que deberían investigarse más ampliamente en los laboratorios microbiológicos, con el fin de definir su significancia clínica

Estudo do comportamento de bactérias amonificantes nos lagos Carioca e D. Helvécio(Vale do Rio Doce-MG) / Study of amnonifying bacteria behavior in the lakes carioca and D. helvecio (Rio doce Valley-MG)

resumo:O estudo do comportamento de bactérias amonificantes nos lagos Carioca e D.Helvécio, pertencentes ao Sistema lacustre natural do Vale do Rio Doce -Minas Gerais -Brasil, durante o período de março e novembro, demonstrou uma variaçäo sazonal similar nos dois lagos, com maior densidade populacional em março e novembro(período chuvoso) e menor densidade em maio, julho e setembro(período seco).A variaçäo vertical também foi relativamente similar para ambos, onde durante a desestratificaçäo térmica a distribuiçäo foi regular em toda a coluna d'áqua, enquanto que durante o periodo de estratificaçäo térmica a densidade populacional foi marcadamente diferente nas várias profundidades.Os tipos amonificantes caracterizados pertencem aos gêneros Acinetobacter, Moraxella e Proteus, revelando em cultura uma alta atividade amonificante com valores que atingiram 30, 8 µg/l de amônia por unidade populacional(10elevado a 5 bactérias/ml)

La flora bucal del adulto en las tres clases de individuos, siempre se a presentado en forma abundante - La flora bucal presenta variaciones y cualitativas, en un individuo a otro - Se observa que esta flora bucal en la mayoria de los individuos ha aumentado en los exámenes hechos por la mañana, en ayunas y antes del aceo bucal - Se ha notado una disminución en la flora bucal durante el día, cuando en el individuo actúan los fenómenos biológicos, fisicos y químicos en la cavidad bucal
