The recently described genus Pandoraea contains five named species (Pandoraea apista, Pandoraea pulmonicola, Pandoraea pnomenusa, Pandoraea sputorum, and Pandoraea norimbergensis) and four unnamed genomospecies. Pandoraea spp. have mainly been recovered from the respiratory tracts of cystic fibrosis (CF) patients. Accurate genus- and species-level identification by routine clinical microbiology...

Maltocin P28 is a phage-tail like bacteriocin produced by Stenotrophomonas maltophilia P28. The ORF8 of maltocin P28 gene cluster is predicted to encode an endolysin and we name it endolysin P28. Sequence analysis revealed that it contains the lysozyme_like superfamily conserved domain. Endolysin P28 has the four consensus motifs as that of Escherichia coli phage lambda gpR. In this study, endo...

Four hundred bacterial isolates were isolated from rhizosphere of some plants collected from Egypt and screened for production of chitinase enzyme. Only four isolates designated MS1, MS2, MS3 and MS4 were the most potent chitinolytic bacterial species. SDS-PAGE analysis of vegetative and sporulated cells of the four isolates revealed that the protein profile of the four isolates were different ...

While the gram-negative bacterium Stenotrophomonas maltophilia is used in biotechnology (e.g., for biological control of plant pathogens and for bioremediation), the number of S. maltophilia diseases in humans has dramatically increased in recent years. A total of 40 S. maltophilia isolates from clinical and environmental sources (plant associated and water) was investigated to determine the in...

Stenotrophomonas maltophilia is a global multidrug-resistant human opportunistic pathogen in clinical environments. Stenotrophomonas maltophilia is also ubiquitous in aqueous environments, soil, and plants. Various molecular typing methods have revealed that S. maltophilia exhibits high levels of phenotypic and genotypic diversity. However, information regarding the genomic diversity within S. ...

Stenotrophomonas maltophilia AAP56, laccase-producing bacteria, growing under different conditions, exhibit laccase activity that is highly affected by some environmental factors. Response surface methodology (RSM) was applied for the determination of laccase factor dependence using two substrates: ABTS (2,2’-azino-bis(3-ethylbenzthiazoline-6sulfonic acid)) and DMP (2,6 Dimethoxy-phenol). RSM w...

BACKGROUND Stenotrophomonas maltophilia (S. maltophilia) is a multiple-antibiotic-resistant opportunistic pathogen that is being isolated with increasing frequency from patients with health-care-associated infections. S. maltophilia is inherently resistant to most of the available antimicrobial agents. Spread of resistant strains has been attributed, in part, to class I integrons. In vitro susc...

Stenotrophomonas maltophilia is an important opportunistic pathogen that affects immunocompromised individuals. In the present study its ability to adhere to mouse tracheal epithelial cells of BALB/c mice as well as to HEp-2 cells was evaluated. All the five clinical isolates used in this study were able to adhere to these biotic surfaces. The involvement of flagella in the adhesion process was...
