Clinical isolates of Klebsiella pneumoniae are divided into three phylogroups and differ in their virulence factor contents. The aim of this study was to determine an association between phylogroup, virulence factors and mortality following bloodstream infection (BSI) caused by Klebsiella pneumoniae. Isolates from all adult patients with BSI caused by K. pneumoniae admitted to Karolinska Univer...

While pathogenic types of Escherichia coli are well characterized, relatively little is known about the commensal E. coli flora. In the current study, antimicrobial resistance in commensal E. coli and distribution of ERIC-PCR genotypes among isolates of such bacteria from cattle and cattle attendants on cattle farms in Tanzania were investigated. Seventeen E. coli genomes representing different...

OBJECTIVES The objective of this study was to examine Klebsiella oxytoca clonal and phylogenetic diversity, based on an international collection of carriage isolates non-susceptible to expanded-spectrum cephalosporins (ESCs). METHODS The study material comprised 68 rectal carriage K. oxytoca isolates non-susceptible to ESCs recovered in 2008-11 from patients in 14 hospitals across Europe and ...

Bovine digital dermatitis (DD) is a severe infectious cause of lameness in cattle worldwide, with important economic and welfare consequences. There are three treponeme phylogroups (T. pedis, T. phagedenis, and T. medium) that are implicated in playing an important causative role in DD. This study was conducted to develop real-time PCR and loop-mediated isothermal amplification (LAMP) assays fo...

Spectral analysis of the cell free extracts of four mat samples colonizing a Great Artesian Bain (GAB) aquifer bore runoff channel suggested that Thermus was present in the 75 degrees C grey mat, Meiothermus was present in the 66 degrees C red mat, a mixed population of Meiothermus/Thermus and photosynthetic microbes were present in the 57 degrees C green mat and photosynthetic microbes were pr...

Objective: Integrons, which are highly effective in capturing, integrating and expressing gene cassettes, play an important role the dissemination of multiple antibiotic resistances. This study investigated correlations integrons uropathogenic E. coli (UPEC) with resistance, virulence phylogeny also relationships phylogroups resistance. Material Methods: Fifty UPECs isolated from uncomplicated ...

Avian colibacillosis is the most common bacterial disease affecting broilers. To better evaluate diversity and origin of causative Escherichia coli strains infecting birds, we conducted a study on 80 broiler flocks. Just before arrival chicks farm, samples were collected in farm environment (walls, feeders, air inlets, etc.) and, upon delivery, day-old (DOCs) transport boxes also sampled. Isola...

Wheat streak mosaic tritimovirus (WSMV) seriously damages wheat worldwide. We report analyses of new complete ORF (CO) sequences from seven Australian isolates with 56 COs and 128 coat protein (CP) genes sequenced previously. Eleven CO three CP were recombinants so removed our analyses. Patristic distances maximum-likelihood phylogenies nonrecombinant (n-rec) their closely correlated (R = 0.994...

Abstract Plant pathogenic strains of Pseudomonas syringae ( Psy ) spp. have been detected in nonagricultural habitats, including those associated with the water cycle. Their presence aquatic systems allows dissemination over long distances, especially irrigation practices. In May 2021, we sampled 15 sites along Danube River Basin Serbia to gain insight into P. abundance and diversity. We identi...

Background: Many bacteria can cause urinary tract infections (UTIs), among which Escherichia coli is the most common causative agent. strains are divided into eight phylogenetic groups based on new Quadroplex-PCR method, different in terms of patterns resistance to antibiotics, virulence, and environmental characteristics. Objectives: This study aimed determine prevalence drug genes E. causing ...
