Frequency of transferable multiple antibiotic resistance amongst coliform bacteria isolated from a treated sewage effluent in Antofagasta, Chile

Antibiotic-resistant coliform bacteria from raw and treated water from activated sludge of a sewage treatment plant were isolated on eosin methylene blue agar (EMB) plates in the separate presence of ampicillin, tetracycline, chloramphenicol and streptomycin. Antibiotic resistant coliforms obtained from ...

Establishment of an in vitro micropropagation protocol for Mecardonia tenella

Mecardonia tenella is an attractive herbaceous native plant, characterized by their intense green foliage and their abundant yellow flowers. It is a very interesting plant for pot and/or garden. A trait to improve in this species is the size of the flowers. The goal of the present paper is to study the i...

Silanol - a novel class of antimicrobial agent

Recently, a significant amount of attention has been directed toward development of novel classes of biocides because of the potential for microbial contamination and infection risks to military personnel and in the general population. We have recently discovered a new and unexpected class of powerful bi...

Growth and antibacterial activity of Lentinula edodes in liquid media supplemented with agricultural wastes

Antibacterial activity of Lentinula edodes against Bacillus subtilis was evaluated in cell-free filtrates obtained after growth in 14 different culture media. The highest B. subtilis growth inhibition was promoted by filtrates of growth media supplemented with rice bran, vermiculite or molasses. L. edode...

Resistencia del Staphylococcus a la meticilina
[Methicillin resistant Staphylococcus]

Medicina (B.Aires); 62 Suppl 2 (), 2002
The pathogenic potential of Staphylococcus aureus is well known as well as its role both in nosocomial and community-acquired infections. When penicillin was introduced by mid ’40s, S. aureus was almost 94...

Construction of a cassette for cloning and analysis of replicons

Acta cient. venez; 51 (1), 2000
The aim of this work was the construction of a cassette, i.e., a non-replicative molecule formed by linkage of an antibiotic resistance gene and a multiple cloning site. This cassette would allow the cloning and analysis of a wide range of replicons. The aac(6')-lc amikacin gene was isolated and ligated ...

Actividad in vitro de trovafloxacina, otras fluoroquinolonas y de diferentes antimicrobianos frente a aislamientos clínicos. Grupo colaborativo WHONET-Argentina
[In vitro activity of trovafloxacin, of other fluoroquinolones and of related antimicrobials against clinical isolates. Grupo colaborativo WHONET-Argentina]

Medicina (B.Aires); 59 Suppl 1 (), 1999
The in vitro activity of trovafloxacin (TRV) has been evaluated in comparison with that of other antimicrobial agents against 5671 clinical isolates recovered by representative institutions of different provinces in our country. The resistance percentage to gentamicin and third generation cephalosporins ...

Estudo experimental da eficácia clínica e microbiológica da associaçäo do diclofenaco sódico e sulfato de gentamicina no tratamento da ceratite por Pseudomonas aeruginosa
Clinical and microbiological effect of sodium diclofenac on gentamicin treatment of experimental Pseudomonas aeruginosa keratitis

Arq. bras. oftalmol; 60 (5), 1997
Objetivo comparar o efeito da associaçäo de diclofenaco sódico 0,1 ppor cento, mais sulfato de gentamicina 0,3 por cento em olhos de coelhos infectados por meio de injeçäo intra-estromal de Pseudomonas aeruginosa, após remoçäo do epitélio da regiäo central da córnea. Métodos: os animais foram...

Avaliaçäo da sensibilidade a antimicrobianos de 87 amostras clínicas de enterococos resistentes à vancomicina
Evaluation of antimicrobial sensitivity of 87 clinical isolates of vancomycin-resistant enterococci

OBEJETIVOS. 1) Avaliar o padräo de sensibilidade in vitro de amostras clínicas de enterococos resitentes à vancomicina (ERV), aos antimicrobianos comumente utilizados no seu tratamento, bem como a antimicrobianos alternativos. 2) Avaliar a acurácia do E test, em comparaçäo aos outros testes de sens...
