1. Variation analysis of bacterial polyhydroxyalkanoates production using saturated and unsaturated hydrocarbons
ABSTRACT Polyhydroxyalkanoates (PHA) are efficient, renewable and environment friendly polymeric esters. These polymers are synthesized by a variety of microbes under stress conditions. This study was carried out to check the suitability of waste frying oil in comparison to other oils for economical bioplastic production. Six bacterial strains were isolated

2. Degradation of polynuclear aromatic hydrocarbons by two strains of Pseudomonas
ABSTRACT The goal of this investigation was to isolate competent polynuclear aromatic hydrocarbons degraders that can utilize polynuclear aromatic hydrocarbons of former industrial sites at McDoel Switchyard in Bloomington, Indiana. Using conventional enrichment method based on soil slurry, we isolated, screened and purified two bacterial species strains PB1

3. Characterization of Lipase from Bacillus subtilisI-4 and Its Potential Use in Oil Contaminated Wastewater
ABSTRACTA lipase producing bacterium was isolated from oil contaminated effluents of various industries from Sheikhupura Road, Pakistan, and, on the basis of biochemical and 16S rRNA ribotyping, was identified asBacillus subtilis. The optimum temperature and pH for the growth of the culture were 37ºC and 7.0, respectively.B. subtilis I-4 had a lag phase of

4. Isolation and characterization of arsenic resistant bacteria from wastewater
The present study proposed the isolation of arsenic resistant bacteria from wastewater. Only three bacterial isolates (MNZ1, MNZ4 and MNZ6) were able to grow in high concentrations of arsenic. The minimum inhibitory concentrations of arsenic against MNZ1, MNZ4 and MNZ6 were 300 mg/L, 300 mg/L and 370 mg/L respectively. The isolated strains showed maximum gro

5. The occurrence and dissemination of methicillin and vancomycin-resistant Staphylococcus in samples from patients and health professionals of a university hospital in Recife, State of Pernambuco, Brazil
Introduction Methicillin-resistant Staphylococcus aureus (MRSA) strains have been responsible for many nosocomial outbreaks. Within hospitals, colonized employees often act as reservoirs for the spread of this organism. This study collected clinical samples of 91 patients admitted to the intensive care unit (ICU), hemodialysis/nephrology service and surgica

6. Disseminação de Salmonella sp na cadeia produtiva do frango de corte
Objetivou-se determinar a resistência antimicrobiana e identificar os ribotipos de 96 cepas de Salmonella isoladas em plantéis avícolas com ciclo completo de produção para estabelecer seu perfil de disseminação. Os maiores percentuais de resistência foram para sulfonamida (56,25%), tetraciclina (53,12%) e amoxacilina (31,25%), enquanto 28,13% dos iso

7. Epidemiologia molecular e resistência a antimicrobianos de amostras de Salmonella spp, isoladas de frangos e perus no período de 2005 e 2006. / Molecular epidemiology and antimicrobial resistance of Salmonella spp, isolated from chicken and turkey between 2005 and 2006
The objective of the study was to evaluate antimicrobial resistance and to characterize the sorovars of Salmonella spp. Isolates from the Programa de Redução de Patógenos (PRP) - Ministério da Agricultura do Brazil. Overall we analysed 1781 Salmonella spp. isolates from chicken broiler and turkey from 2005 to 2009 at different slaughter-houses and certif

8. Antimicrobial resistance and PCR-ribotyping of Shigella responsible for foodborne outbreaks occurred in southern Brazil
Little information about Shigella responsible for foodborne shigellosis is available in Brazil. The present study aimed to investigate the antimicrobial resistance and PCR-ribotyping patterns of Shigella isolates responsible for foodborne outbreaks occurred in Rio Grande do Sul State (RS), Southern Brazil in the period between 2003 and 2007. Shigella strains

9. Molecular typing and biological characteristics of Pseudomonas aeruginosa isolated from cystic fibrosis patients in Brazil
The present study had as objective to evaluate the genotypic diversity and biological characteristics, such as hemolysin, protease, elastase of 56 clinical strains of Pseudomonas aeruginosa isolated from 13 cystic fibrosis (CF) patients attending at the School Hospital of Campinas State University (UNICAMP), Brazil. Genotypic diversity has been determined by

10. Cross-transmission of vancomycin-resistant Enterococcus in patients undergoing dialysis and kidney transplant
The objective of this study was to investigate the occurrence of vancomycin-resistant Enterococcus (VRE) cross-transmission between two patient groups (long-term dialysis and kidney transplant patients). Molecular typing, by automated ribotyping with the RiboPrinter Microbial Characterization System (Qualicon, USA), was used to analyze VRE isolates from 31 f

11. Phenotyping and genotyping methods applied to investigate the relatedness of brazilian isolates of enterobacter cloacae
In order to evaluate the resolving power of several typing methods to identify relatedness among Brazilian strains of Enterobacter cloacae, we selected twenty isolates from different patients on three wards of a University Hospital (Orthopedics, Nephrology, and Hematology). Traditional phenotyping methods applied to isolates included biotyping, antibiotic se

12. Isolamento, identificação e caracterização de Shigella spp. envolvidas em surtos alimentares no Rio Grande do Sul / Isolation, identification, and characterization of Shigella spp. associated with foodborne outbreaks occurred in Rio Grande do Sul State, Brazil
No Brasil existem poucos relatos sobre casos de Shigelose, um fator que contribui com o pouco conhecimento a respeito dessa doença. Além disso, a falta de obrigatoriedade por parte da legislação vigente em relação à pesquisa de Shigella tem contribuído com este fato. O presente trabalho teve por objetivo isolar, identificar e caracterizar isolados de
