1. Targeting of Virulence Factors and Plasmid Profiling of Klebsiella pneumoniae Causing Urinary Tract Infection in Sylhet City of Bangladesh
ABSTRACT Studies were conducted to characterize Klebsiella pneumoniae isolates from urinary tract infection (UTI) patients in Sylhet city of Bangladesh. At the same time, all isolates were screened for some common virulence genes and four significant isolates were searched for plasmid number and sizes by mini alkaline-lysis method. Among five tested isolates

2. Genome sequence of a multidrug-resistant Corynebacterium striatum isolated from bloodstream infection from a nosocomial outbreak in Rio de Janeiro, Brazil
Multidrug-resistant (MDR) Corynebacterium striatum has been cited with increased frequency as pathogen of nosocomial infections. In this study, we report the draft genome of a C. striatum isolated from a patient with bloodstream infection in a hospital of Rio de Janeiro, Brazil. The isolate presented susceptibility only to tetracycline, vancomycin and linezo

3. Antimicrobial resistance and plasmid replicons in Yersinia enterocolitica strains isolated in Brazil in 30 years
Abstract Some studies evaluated the resistance profile of the Y. enterocolitica strains isolated in diverse countries. However, in Brazil the isolation and the study of Y. enterocolitica are not common and therefore information about the antimicrobial resistance profile of this species in this country is scarce. Therefore, the aim of this study was to evalua

4. Plasmid patterns of efficient and inefficient strains of Bacillus thuringiensis against Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae)
Bacillus thuringiensis harbors genes encoding Cry proteins found in chromosomes or plasmids of different sizes (4-150 Mb). Although the smaller plasmids are more abundant in B. thuringiensis, their specific function is unknown. As for the megaplasmids, their main recognized function is to harbor cry genes, although the sequencing of some of these plasmids in

5. Characterization of an Argentine isolate of Bacillus thuringiensis similar to the HD-1 strain
We report the characterization of an Argentine isolate of Bacillus thuringiensis (INTA TA24-6) similar to the HD-1 strain, which harbors a cryptic cry2Ab gene that apparently is transcribed but not translated into a protein. INTA TA24-6 showed a Rep-PCR pattern identical to the HD-1 strain, a plasmid pattern that resembled that of this strain and cry1 and cr

6. AmpC beta lactamases among Gram negative clinical isolates from a tertiary hospital, South India
AmpC β-lactamases are cephalosporinases that hydrolyze cephamycins as well as other extended-spectrum cephalosporins and are poorly inhibited by clavulanic acid. Although reported with increasing frequency, the true rate of occurrence of AmpC β-lactamases in different organisms, including members of Enterobacteriaceae, remains unknown. The present study wa

7. Produção de mutantes de Streptomyces clavuligerus nos genes lat, cvm7P e rpoZ e estudo de seus efeitos sobre a produção de ácido clavulânico / Production of Streptomyces clavuligerus mutants in the genes lat, cvm7P and rpoZ, and study their effects on acid production clavulanic
Molecular biology and genetic engineering have been deployed widely in recent years, several protocols have been established, presenting new methodologies capable of altering the genetics of bacterial strains industrial interest. This research had as main objectives: (1) the construction of the following plasmids: plat, pAMB4 and pAMB3RpoZneo, (2) th

9. Early colonization pattern of maize (Zea mays L. Poales, Poaceae) roots by Herbaspirillum seropedicae (Burkholderiales, Oxalobacteraceae)
The bacterium Herbaspirillum seropedicae is an endophytic diazotroph found in several plants, including economically important poaceous species. However, the mechanisms involved in the interaction between H. seropedicae and these plants are not completely characterized. We investigated the attachment of Herbaspirillum to maize roots and the invasion of the r

10. ESTUDOS GENÉTICOS SOBRE A VIRULÊNCIA DE Escherichia coli ENTEROAGREGATIVA ATÍPICA / Genetic studies on the virulence of atypical enteroaggregative Escherichia coli.
Escherichia coli enteroaggregative (EAEC) is emerging as a significant diarrheal pathogen. EAEC is defined by its characteristic stacked brick aggregative adherence (AA) pattern of adherence to HEp-2 cells. Most EAEC strains harbor a 60 to 65-MDa virulence plasmid (pAA). A 1-Kb fragment of pAA, referred to as the AA probe or CVD432, has been widely used for

11. Analise comparativa da expressão de genes de Xylella fastidiosa associados a patogenicidade e formação de biofilme
The main goal of this study is to survey the expression of genes possibly involved in the pathogenicity of strain 9a5c of X. fastidiosa. Freshly-isolated bacteria from symptomatic plants (first passage condition or FP) as well as bacteria obtained after 46 transfers to axenic culture (several passage condition or SP) were utilized in this work. A possible lo

12. Characterization of Neisseria gonorrhoeae strains isolated from patients with conjunctivitis
The conjunctivitis produced by Neisseria gonorrhoeae is the less frequently reported clinical form of gonococcal infection. We aim to phenotypically characterize N. gonorrhoeae isolated from conjunctivae sites. A total of six cases of this disease were notified in the Camagüey province, Cuba. All the strains isolated were penicillin-producing, showed the se
