Abstract:
ESBL-producing enterobacteria have a significant impact on public health as they provide antibiotic resistance. Little is known about the relative diversity in various types of biotopes in the same geographical area. This study aimed to determine their diversity and abundance in 3 different aquatic environments. Samples from wells, river water, and hospital wastewater were analyzed. ESBL-producing enterobacteria isolated were identified using double-disk synergy test method based on enzymatic tests. Results showed that the abundance of total enterobacteria in log (CFU/100 µL) varied from 0.60

Abstract:
Dipterocarpaceae is a group of native, predominant trees of Indonesia lowland tropical forest. It is now under a serious threat of extinction due to continual forest degradations. Although dipterocarps have been used for reforestation, in the case of peat forests, transplanted seedlings typically suffer low survivar rates due to acidie soil, low nutrient content, and the presence of toxic elements. To produce robust seedlings, many studies have suggested  an inclusion of plant growth-promoting rhizobacteri (PGPR). However little or no studies have been done to PGPR of dipterocarps. This s

Prophages are abundant elements integrated into bacterial genomes and contribute to inter-strain genetic variability and, in some cases, modulate the environmental behavior of bacteria, such as pathogen virulence. Here, we described prophage occurrence and diversity in publicly available Erwinia genome assemblies, a genus containing plant pathogens. Prophage-like sequences were identified and taxonomically classified. Sequence diversity was analyzed through intergenomic similarities. Furthermore, we searched for anti-phage defense systems in Erwinia spp., such as DISARM, BREX, and CRISPR-Cas s

Abstract:
In a genomic library of Erwinia amylovora, a locus has been identified that can suppress an Erwinia stewartii rcsA mutant. In addition, the locus induced a mucoid sticky phenotype of colonies in a wild-type strain of Erwinia stewartii and increased exopolysaccharide synthesis in several species of bacteria belonging to the genus Erwinia. An open reading frame was identified at this locus encoding a 225 amino acid protein that contained a helix-turn-helix motif typical of transcriptional regulators. The corresponding gene was subsequently named rcsV (regulator of capsular synthesis affecting vi

Sequences of 16S rDNAs and the intergenic spacer (IGS) regions between the 16S and 23S rDNA of bacterial strains from genus Erwinia were determined. Comparison of 16S rDNA sequences from different species and subspecies clearly revealed intraspecies–subspecies homology and interspecies heterogeneity. Phylogenetic analyses of 16S rDNA sequence data revealed that Erwinia spp. formed a discrete monophyletic clade with moderate to high bootstrap values. PCR amplification of the 16S–23S rDNA regions using primers complementary to the 3' end of 16S and 5' end of 23S rRNA genes generated two DNA frag

Gram-negative plant pathogenic bacteria employ specialized type-III secretion systems (TTSS) to deliver an arsenal of pathogenicity proteins directly into host cells. These secretion systems are encoded by hrp genes (for hypersensitive response and pathogenicity) and the effector proteins by so-called dsp or avr genes. The functions of effectors are to enable bacterial multiplication by damaging host cells and/or by blocking host defenses. We characterized essential hrp gene clusters in the Stewart's Wilt of maize pathogen, Pantoea stewartii subsp. stewartii (Pnss; formerly Erwinia stewartii)
