A taxonomic study of bacteria isolated from grasses: a proposed new species Pseudomonas graminis sp. nov. (1/4816)

The taxonomic position of a yellow-pigmented group of bacteria, isolated from the phyllosphere of grasses was investigated. Results obtained from restriction analysis of amplified 16S rDNA with seven endonucleases (CfoI, HaeIII, AluI, HinfI, MspI, Sau3A and ScrFI) showed identical restriction patterns for each enzyme of all isolates studied, which suggests that all strains belong to the same species. The grass isolates displayed the characteristics of the genus Pseudomonas. They were Gram-negative, aerobic and rod-shaped with polar flagella. Isolates were catalase-positive and oxidase-negative, and unable to oxidize or ferment glucose with the production of acid. The isolates did not reduce nitrate to nitrite but were able to utilize a wide range of compounds individually as a sole carbon source, with preference being given to the utilization of monosaccharides. The disaccharides tested were not utilized as substrates. The DNA base compositions of the tested strains ranged from 60 to 61 mol% G+C. The major isoprenoid quinone of each was ubiquinone Q-9 and hydroxy fatty acids were represented by 3-hydroxydodecanoic acid and 2-hydroxydodecanoic acid. Comparison of 16S rDNA sequences showed that the bacteria were members of the genus Pseudomonas, with similarity values between 91.5 and 97.7%. DNA-DNA hybridization studies with closely related neighbours revealed a low level of homology (< 27%), indicating that the isolates represent an individual species. On the basis of phenotypic and phylogenetic analyses a new species, Pseudomonas graminis sp. nov. (type strain DSM 11363T), is proposed.  (+info)

Cellular fatty acids and metabolic products of Pseudomonas species obtained from clinical specimens. (2/4816)

The cellular fatty acid composition of 112 reference strains and clinical isolates of Pseudomonas species was determined by gas-liquid chromatography (GLC). The presence and relative amounts of cyclopropane, hydroxy, and branched-chain fatty acids were distinguishing features of these strains. Determination of short-chain fatty acids extracted from spent growth media provided an additional means for identifying some strains. Our results show that clinical isolates of pseudomonads can be divided into eight distinct GLC groups. The procedures were especially useful for distinguishing glucose-nonoxidizing pseudomonads, which are difficult to identify by conventional criteria. Since the GLC procedures are simple, rapid, and highly reproducible, they are useful in diagnostic laboratories that process large numbers of cultures. Coupled with selected conventional tests, the analysis of short-chain and cellular fatty acids can be very useful for rapid screening of clinical isolates of Pseudomonas species.  (+info)

Synthesis of bacteriophage phi6 double-stranded ribonucleic acid. (3/4816)

Uracil was incorporated into all three bacteriophage phi6 dsRNA segments throughout the infection cycle; the rates of incorporation into each of the three segments were approx. constant for the first 15 to 20 min and then increased rapidly until 50 min after infection. The medium and small dsRNA segments were produced in greater amounts than the large dsRNA segment at all times in the infection cycle. Inhibition of host RNA and protein synthesis with rifampin and chloramphenicol revealed that virus dsRNA synthesis immediately after infection was independent of either host function.  (+info)

The PalkBFGHJKL promoter is under carbon catabolite repression control in Pseudomonas oleovorans but not in Escherichia coli alk+ recombinants. (4/4816)

The alk genes are located on the OCT plasmid of Pseudomonas oleovorans and encode an inducible pathway for the utilization of n-alkanes as carbon and energy sources. We have investigated the influence of alternative carbon sources on the induction of this pathway in P. oleovorans and Escherichia coli alk+ recombinants. In doing so, we confirmed earlier reports that induction of alkane hydroxylase activity in pseudomonads is subject to carbon catabolite repression. Specifically, synthesis of the monooxygenase component AlkB is repressed at the transcriptional level. The alk genes have been cloned into plasmid pGEc47, which has a copy number of about 5 to 10 per cell in both E. coli and pseudomonads. Pseudomonas putida GPo12 is a P. oleovorans derivative cured of the OCT plasmid. Upon introduction of pGEc47 in this strain, carbon catabolite repression of alkane hydroxylase activity was reduced significantly. In cultures of recombinant E. coli HB101 and W3110 carrying pGEc47, induction of AlkB and transcription of the alkB gene were no longer subject to carbon catabolite repression. This suggests that carbon catabolite repression of alkane degradation is regulated differently in Pseudomonas and in E. coli strains. These results also indicate that PalkBFGHJKL, the Palk promoter, might be useful in attaining high expression levels of heterologous genes in E. coli grown on inexpensive carbon sources which normally trigger carbon catabolite repression of native expression systems in this host.  (+info)

Purification and characterization of gentisate 1,2-dioxygenases from Pseudomonas alcaligenes NCIB 9867 and Pseudomonas putida NCIB 9869. (5/4816)

Two 3-hydroxybenzoate-inducible gentisate 1,2-dioxygenases were purified to homogeneity from Pseudomonas alcaligenes NCIB 9867 (P25X) and Pseudomonas putida NCIB 9869 (P35X), respectively. The estimated molecular mass of the purified P25X gentisate 1, 2-dioxygenase was 154 kDa, with a subunit mass of 39 kDa. Its structure is deduced to be a tetramer. The pI of this enzyme was established to be 4.8 to 5.0. The subunit mass of P35X gentisate 1, 2-dioxygenase was 41 kDa, and this enzyme was deduced to exist as a dimer, with a native molecular mass of about 82 kDa. The pI of P35X gentisate 1,2-dioxygenase was around 4.6 to 4.8. Both of the gentisate 1,2-dioxygenases exhibited typical saturation kinetics and had apparent Kms of 92 and 143 microM for gentisate, respectively. Broad substrate specificities were exhibited towards alkyl and halogenated gentisate analogs. Both enzymes had similar kinetic turnover characteristics for gentisate, with kcat/Km values of 44.08 x 10(4) s-1 M-1 for the P25X enzyme and 39.34 x 10(4) s-1 M-1 for the P35X enzyme. Higher kcat/Km values were expressed by both enzymes against the substituted gentisates. Significant differences were observed between the N-terminal sequences of the first 23 amino acid residues of the P25X and P35X gentisate 1,2-dioxygenases. The P25X gentisate 1,2-dioxygenase was stable between pH 5.0 and 7.5, with the optimal pH around 8.0. The P35X enzyme showed a pH stability range between 7.0 and 9.0, and the optimum pH was also 8.0. The optimal temperature for both P25X and P35X gentisate 1, 2-dioxygenases was around 50 degrees C, but the P35X enzyme was more heat stable than that from P25X. Both enzymes were strongly stimulated by 0.1 mM Fe2+ but were completely inhibited by the presence of 5 mM Cu2+. Partial inhibition of both enzymes was also observed with 5 mM Mn2+, Zn2+, and EDTA.  (+info)

Molecular characterization of the genes pcaG and pcaH, encoding protocatechuate 3,4-dioxygenase, which are essential for vanillin catabolism in Pseudomonas sp. strain HR199. (6/4816)

Pseudomonas sp. strain HR199 is able to utilize eugenol (4-allyl-2-methoxyphenol), vanillin (4-hydroxy-3-methoxybenzaldehyde), or protocatechuate as the sole carbon source for growth. Mutants of this strain which were impaired in the catabolism of vanillin but retained the ability to utilize eugenol or protocatechuate were obtained after nitrosoguanidine mutagenesis. One mutant (SK6169) was used as recipient of a Pseudomonas sp. strain HR199 genomic library in cosmid pVK100, and phenotypic complementation was achieved with a 5.8-kbp EcoRI fragment (E58). The amino acid sequences deduced from two corresponding open reading frames (ORF) identified on E58 revealed high degrees of homology to pcaG and pcaH, encoding the two subunits of protocatechuate 3,4-dioxygenase. Three additional ORF most probably encoded a 4-hydroxybenzoate 3-hydroxylase (PobA) and two putative regulatory proteins, which exhibited homology to PcaQ of Agrobacterium tumefaciens and PobR of Pseudomonas aeruginosa, respectively. Since mutant SK6169 was also complemented by a subfragment of E58 that harbored only pcaH, this mutant was most probably lacking a functional beta subunit of the protocatechuate 3, 4-dioxygenase. Since this mutant was still able to grow on protocatechuate and lacked protocatechuate 4,5-dioxygenase and protocatechuate 2,3-dioxygenase, the degradation had to be catalyzed by different enzymes. Two other mutants (SK6184 and SK6190), which were also impaired in the catabolism of vanillin, were not complemented by fragment E58. Since these mutants accumulated 3-carboxy muconolactone during cultivation on eugenol, they most probably exhibited a defect in a step of the catabolic pathway following the ortho cleavage. Moreover, in these mutants cyclization of 3-carboxymuconic acid seems to occur by a syn absolute stereochemical course, which is normally only observed for cis, cis-muconate lactonization in pseudomonads. In conclusion, vanillin is degraded through the ortho-cleavage pathway in Pseudomonas sp. strain HR199 whereas protocatechuate could also be metabolized via a different pathway in the mutants.  (+info)

Contrasting effects of a nonionic surfactant on the biotransformation of polycyclic aromatic hydrocarbons to cis-dihydrodiols by soil bacteria. (7/4816)

The biotransformation of the polycyclic aromatic hydrocarbons (PAHs) naphthalene and phenanthrene was investigated by using two dioxygenase-expressing bacteria, Pseudomonas sp. strain 9816/11 and Sphingomonas yanoikuyae B8/36, under conditions which facilitate mass-transfer limited substrate oxidation. Both of these strains are mutants that accumulate cis-dihydrodiol metabolites under the reaction conditions used. The effects of the nonpolar solvent 2,2,4, 4,6,8,8-heptamethylnonane (HMN) and the nonionic surfactant Triton X-100 on the rate of accumulation of these metabolites were determined. HMN increased the rate of accumulation of metabolites for both microorganisms, with both substrates. The enhancement effect was most noticeable with phenanthrene, which has a lower aqueous solubility than naphthalene. Triton X-100 increased the rate of oxidation of the PAHs with strain 9816/11 with the effect being most noticeable when phenanthrene was used as a substrate. However, the surfactant inhibited the biotransformation of both naphthalene and phenanthrene with strain B8/36 under the same conditions. The observation that a nonionic surfactant could have such contrasting effects on PAH oxidation by different bacteria, which are known to be important for the degradation of these compounds in the environment, may explain why previous research on the application of the surfactants to PAH bioremediation has yielded inconclusive results. The surfactant inhibited growth of the wild-type strain S. yanoikuyae B1 on aromatic compounds but did not inhibit B8/36 dioxygenase enzyme activity in vitro.  (+info)

Evolution by small steps and rugged landscapes in the RNA virus phi6. (8/4816)

Fisher's geometric model of adaptive evolution argues that adaptive evolution should generally result from the substitution of many mutations of small effect because advantageous mutations of small effect should be more common than those of large effect. However, evidence for both evolution by small steps and for Fisher's model has been mixed. Here we report supporting results from a new experimental test of the model. We subjected the bacteriophage phi6 to intensified genetic drift in small populations and caused viral fitness to decline through the accumulation of a deleterious mutation. We then propagated the mutated virus at a range of larger population sizes and allowed fitness to recover by natural selection. Although fitness declined in one large step, it was usually recovered in smaller steps. More importantly, step size during recovery was smaller with decreasing size of the recovery population. These results confirm Fisher's main prediction that advantageous mutations of small effect should be more common. We also show that the advantageous mutations of small effect are compensatory mutations whose advantage is conditional (epistatic) on the presence of the deleterious mutation, in which case the adaptive landscape of phi6 is likely to be very rugged.  (+info)

Pseudomonas cichorii is a Gram-negative soil bacterium that is pathogenic to plants. It has a wide host range, and can have an important economical impact on lettuce, celery and chrysanthemum crops. P. cichorii was first isolated on endives (Cichorium endivia), from which it derives its name. It produces 6-aminopenicillanic acid. Based on 16S rRNA analysis, P. cichorii has been placed in the P. syringae group. Pseudomonas cichorii is non-host specific as it does not infect just one host. Its host range includes lettuce, pepper, celery, coffee, wheat, basil and several other host plants. Symptoms of the causal agent vary depending on the host and the area of the plant infected. In general, pseudomonas cichorii is seen to cause leaf blighting and spotting. The first appearance of symptoms involves a water soaked lesion that develops at the edge of the leaf, midvein or randomly across the leaf These lesions progressively turn black or brown and may be surrounded by yellow halos. These lesions also ...
Thirty-three fluorescent Pseudomonas strains isolated from tomato pith necrosis (FPTPN strains) and 89 Pseudomonas corrugata strains were studied by numerical taxonomy. In the dendrogram of distances, the P. corrugata strains constituted a single phenon (phenon 1), whereas 17 of the 33 FPTPN strains clustered in a separate phenon (phenon 2). The other 16 FPTPN strains were included in phena consisting of well-characterized fluorescent Pseudomonas species or were isolated phenotypes. Phena 1 and 2 were distinguished by fluorescence on King B medium, accumulation of poly-β;-hydroxybutyrate, production of levan, and assimilation of sorbitol. DNA-DNA hybridization showed that P. corrugata is a true genomic species (66 to 100% DNA relatedness) and that the FPTPN strains of phenon 2 were divided into three genomic groups. Genomic groups 1 and 2 were not distinct from each other phenotypcally, and genomic group 3 could be distinguished from genomic groups 1 and 2 only on the basis of assimilation of

Pseudomonas viridiflava is a pectinolytic bacterium member of the Pseudomonas syringae group (1). It is pathogenic to numerous cultivated crops and weeds (2), including Arabidopsis thaliana, in which it induces both compatible (disease) and incompatible (resistance) responses (3). For this reason, it has triggered much interest in plant-microbe interaction studies in A. thaliana (4, 5).. Pathogenicity genes and mechanisms are becoming increasingly well-known, and 2 paralogous pathogenicity islands (T-PAI and S-PAI), which share many gene homologs, have been described for P. viridiflava (6, 7).. P. viridiflava was shown to display a high level of genetic variation worldwide, with all isolated P. viridiflava strains parting into two distinct and deeply diverged clades, with evidence of frequent recombination but little geographic differentiation (4, 5). These 2 distinct clades cause disease symptoms of differing severities.. This bacterium is an antimycotic producer that is usable in biological ...
The effect of plasmid CAM-OCT on responses to UV irradiation was compared in Pseudomonas aeruginosa, in Pseudomonas putida, and in Pseudomonas putida mutants carrying mutations in UV response genes. CAM-OCT substantially increased both survival and mutagenesis in the two species. P. aeruginosa strains without CAM-OCT exhibited much higher UV sensitivity than did P. putida strains. UV-induced mutagenesis of plasmid-free P. putida was easily detected in three different assays (two reversion assays and one forward mutation assay), whereas UV mutagenesis of P. aeruginosa without CAM-OCT was seen only in the forward mutation assay. These results suggest major differences in DNA repair between the two species and highlight the presence of error-prone repair functions on CAM-OCT. A number of P. putida mutants carrying chromosomal mutations affecting either survival or mutagenesis after UV irradiation were isolated, and the effect of CAM-OCT on these mutants was determined. All mutations producing a ...
The chromosomal DNA was isolated and purified from 17 strains of Pseudomonas paucimobilis, and from the type or reference strains of Flavobacterium capsulatum, F. devorans, F. multivorum, Chromobacterium lividum, Xanthomonas campestris and seven species of Pseudomonas. The DNA base compositions (mol%G + C) of P. paucimobilis strains were between 62·2 and 68·6%, and typical strains had a mean value of 65·3 ± 0·4 mol %, determined from thermal denaturation temperature. DNA-DNA molecular hybridization with 3H-labelled probe DNA from NCTC 11030 P. paucimobilis (the type strain) indicated that the species comprised a core of 13 closely related strains (74 to 96%), which included F. devorans NCIB 8195 (= ATCC 10829). Four P. paucimobilis strains displayed lower levels of hybridization (≤ 38%). The hybridization results showed that P. paucimobilis was not closely related to allied yellow-pigmented bacteria or to other reference pseudomonads. The electrophoretic protein patterns of representative
Pseudomonas amygdali is a Gram-negative plant pathogenic bacterium. It is named after its ability to cause disease on almond (Prunus amygdalus) trees. Different analyses, including 16S rRNA analysis, DNA-DNA hybridization, and MLST clearly placed P. amygdali in the P. syringae group together with the species Pseudomonas ficuserectae and Pseudomonas meliae, and 27 pathovars of Pseudomonas syringae/Pseudomonas savastanoi, constituting a single, well-defined phylogenetic group which should be considered as a single species. This phylogenetic group has not been formally named because of the lack of reliable means to differentiate it phenotipically from closely related species, and it is currently known as either genomospecies 2 or phylogroup 3. When it is formally named, the correct name for this new species should be Pseudomonas amygdali, which takes precedence over all the other names of taxa from this group, including Pseudomonas savastanoi, which is and inadequate and confusing name whose use is ...

The broad and vague phenotypic definition allowed the genus Pseudomonas to become a dumping ground for incompletely characterized polarly flagellated, gram-negative, rod-shaped, aerobic bacteria, and a large number of species have been accommodated in the genus Pseudomonas. The 16S rRNA sequences of 128 valid and invalid Pseudomonas species, which included almost valid species of the genus Pseudomonas listed in the Approved Lists of Bacterial Names, were obtained: sequences of 59 species were determined and those of 69 species were obtained from the GenBank/EMBL/DDBJ databases. These sequences were compared with the sequences of other species of the Proteobacteria. Fifty-seven valid or invalid species including Pseudomonas aeruginosa (type species of the genus Pseudomonas Migula 1894) belonged to the genus Pseudomonas (sensu stricto). Seven subclusters were formed in the cluster of the genus Pseudomonas (sensu stricto), and the resulting clusters conformed well to the rRNA-DNA hybridization study by

In this study, the efficient phosphate utilizing isolates were used to remove phosphate from synthetic phosphate wastewater was tested using batch scale process. Hence the objective of the present study was to examine the efficiency of bacterial species individually for the removal of phosphate from synthetic phosphate wastewater. The most efficient phosphate reducers were isolated and screened from eutrophic lake water samples. The total heterotrophic bacterial analysis of the samples showed the presence of about 22 phosphate reducers. Among them, Pseudomonas sp YLW-7 were found to be efficient in phosphate reduction based on the maximum phosphate ultization which was observed by plate screening method using the minimum inhibitory concentration (MIC) test. The effect of carbon sources (glucose, starch, sucrose and lactose) at 0.5% on the removal of phosphate by Pseudomonas sp YLW7 was estimated. The maximum growth of Pseudomonas sp YLW7 was observed to be 0.9886 OD in glucose followed by starch ...

Pseudomonas species are opportunistic pathogens with implications in a wide range of diseases including cystic fibrosis and sickle cell anaemia. Because of their status as multidrug resistant (MDR) and extremely drug resistant (XDR) bacteria Pseudomonas species represent a threat to public health. Prevalence, antibiogram and associated antibiotic resistant genes of Pseudomonas species isolated from freshwater and mixed liquor environments in the Eastern Cape Province of South Africa were assessed. Polymerase chain reaction (PCR) based technique was used to identify the isolates and screen for antibiotic resistant genes. The result shows occurrence of Pseudomonas spp. in freshwater and mixed liquor as follows: 71.42% and 37.5% (P. putida), 14.28% and 31.25% (P. flourescens), 7.14% and 6.25% (P. aeruginosa) and 7.14% and 25% for other Pseudomonas species respectively.

This study analysed the phenotypic and genotypic variation among 511 Pseudomonas savastanoi pv. phaseolicola (Psp) isolates, causing halo blight in mungbeans. Collected from symptomatic mungbean (Vigna radiata) crops throughout Australia between 2005 and 2018, a total of 352 Psp isolates were phenotypically screened. Our in planta screening against a set of four mungbean cultivars with known susceptible and resistant reactions revealed five distinctive pathotypes. Isolates belonging to pathotype 2 were the most prevalent at 84% and were found to be highly pathogenic towards all tested mungbean genotypes. Genomic variation was investigated for 205 isolates using DNA fingerprints, splitting the halo blight pathogen population into two broad genetic lineages. Further genetic testing for two known avirulence genes, avrPphE and avrPphF, identified the avrPphE gene in all the tested isolates and avrPphF present in all but two. To identify candidate avirulence genes unique to Psp isolates infecting ...

AU - Alfano, James R.. AU - Bauer, David W.. AU - Milos, Timothy M.. AU - Collmer, Alan. PY - 1996. Y1 - 1996. N2 - Pseudomonas syringae pv. syringae, like many plant pathogenic bacteria, secretes a harpin protein that can elicit the hypersensitive response (HR), a defensive cellular suicide, in non-host plants. The harpin-encoding hrpZ gene is located in an operon that also encodes Hrp secretion pathway components and is part of the functional cluster of hrp genes carried on cosmid pHIR11 that enables saprophytic bacteria like Escherichia coli and Pseudomonas fluorescens to elicit the HR in tobacco leaves. We have constructed functionally non-polar hrpZ deletion mutations, revealing that HrpZ is necessary for saprophytic bacteria carrying pHIR11 to ...
Pseudomonas syringae pathovar phaseolicola ATCC ® BAA-978D™ Designation: Genomic DNA from Pseudomonas syringae pathovar phaseolicola strain 1448A TypeStrain=False Application:
Pseudomonas syringae is pathogenic in a wide variety of plants, causing diseases with economic impacts. Pseudomonas syringae pathovars produce several toxins that can function as virulence factors and contribute to disease symptoms. These virulence factors include antimetabolite toxins, such as tabtoxin, phaseolotoxin and mangotoxin, which target enzymes in the pathways of amino acid metabolism. The antimetabolite toxins are generally located in gene clusters present in the flexible genomes of specific strains. These gene clusters are typically present in blocks of genes that appear to be integrated into specific sites in the P. syringae core genome. A general overview of the genetic organization and biosynthetic and regulatory functions of these genetic traits of the antimetabolite toxins will be given in the present work.
TY - JOUR. T1 - The hrpK operon of Pseudomonas syringae pv. tomato DC3000 encodes two proteins secreted by the type III (Hrp) protein secretion system. T2 - HopB1 and HrpK, a putative type III translocator. AU - Petnicki-Ocwieja, Tanja. AU - Van Dijk, Karin. AU - Alfano, James R.. PY - 2005/1. Y1 - 2005/1. N2 - Pseudomonas syringae is a gram-negative bacterial plant pathogen that is dependent on a type III protein secretion system (TTSS) and the effector proteins it translocates into plant cells for pathogenicity. The P. syringae TTSS is encoded by hrp-hrc genes that reside in a central region of a pathogenicity island (Pai). Flanking one side of this Pai is the exchangeable effector locus (EEL). We characterized the transcriptional expression of the open reading frames (ORFs) within the EEL of P. syringae pv. tomato DC3000. One of these ORFs, PSPTO1406 (hopB1) is expressed in the same transcriptional unit as hrpK. Both HopB1 and HrpK were secreted in culture and translocated into plant cells ...
Pseudomonas syringae pv. savastanoi y P. syringae pv. phaseolicola son dos patógenos de plantas, incluidos en los 60 patovares del grupo P. syringae. Las dos bacterias causan enfermedad en diferentes huéspedes y con síntomas muy distintos, la primera tumores en olivo y la segunda lesiones en judía, y son organismos modelos de estudio en la identificación de los determinantes que definen el espectro de huésped. La definición del espectro de huésped puede estar determinada por la acción conjunta de proteínas llamadas efectores, que son secretadas por un sistema de secreción tipo III a la célula vegetal, dando lugar a la inhibición de las respuestas de defensa de la planta. El objetivo del trabajo ha sido la identificación de genes de efectores de P. syringae pv. savastanoi que induzcan respuesta de incompatibilidad en judía, para lo que se abordó la clonación y ensayo de 11 efectores. De éstos, sólo se pudieron obtener clones de los efectores AER-0000629 y AER-0001936, que se ...
Pseudomonas putida KT2440 is the only fully sequenced P. putida strain. Thus, for transcriptomics and proteomics studies with other P. putida strains, the P. putida KT2440 genomic database serves as standard reference. The utility of KT2440 whole-genome, high-density oligonucleotide microarrays for transcriptomics studies of other Pseudomonas strains was investigated. To this end, microarray hybridizations were performed with genomic DNAs of subcultures of P. putida KT2440 (DSM6125), the type strain (DSM291T), plasmid pWW0-containing KT2440-derivative strain mt-2 (DSM3931), the solvent-tolerant P. putida S12, and several other Pseudomonas strains. Depending on the strain tested, 22 to 99% of all genetic elements were identified in the genomic DNAs. The efficacy of these microarrays to study cellular function was determined for all strains included in the study. The vast majority of DSM6125 genes encoding proteins of primary metabolism and genes involved in the catabolism of aromatic compounds ...
Carbapenems are critically important antimicrobials as a last line of defense against multidrug-resistant Gram-negative bacterial infections (1, 2). As such, the increasing prevalence of carbapenemase-producing isolates in animal husbandry is of great concern. While the metallo-β-lactamase (MBL)-producing bacteria have been commonly identified from food animals (3-7), blaMBL-carrying Pseudomonas spp. are rarely reported in animal husbandry or the surrounding environment. Although we have reported the high prevalence of NDM in Enterobacteriaceae isolates from poultry production in Shandong Province (7), carbapenemase-producing non-Enterobacteriaceae isolates have not been identified in the same region. Here, we report four chromosome-borne VIM-positive Pseudomonas isolates: one Pseudomonas aeruginosa isolate from a swallow (Yanornis martini), one Pseudomonas putida isolate from a fly, and two P. putida isolates from chickens. The blaVIM-2 gene was identified in the P. aeruginosa isolate, but 27 ...

Competition among indigenous and inoculated 2,4-dichlorophenoxyacetic acid (2,4-D)-degrading bacteria was studied in a native Kansas prairie soil following 2,4-D additions. The soil was inoculated with four different 2,4-D-degrading strains at densities of 10(3) cells per g of soil; the organisms used were Pseudomonas cepacia DBO1(pJP4) and three Michigan soil isolates, strain 745, Sphingomonas paucimobilis 1443, and Pseudomonas pickettii 712. Following 2,4-D additions, total soil DNA was extracted and analyzed on Southern blots by using a tfdA gene probe which detected three of the strains and another probe that detected the fourth strain, S. paucimobilis 1443, which belongs to a different class of 2,4-D degraders. P. cepacia DBO1(pJP4), a constructed strain, outcompeted the other added strains and the indigenous 2,4-D-degrading populations. The S. paucimobilis population was the secondary dominant population, and strain 745 and P. pickettii were not detected. Relative fitness coefficients determined
Bacterial stem blight of alfalfa occurs sporadically in the central and western U.S. Yield losses of up to 50% of the first harvest can occur with some cultivars. Developing resistant cultivars is hampered by lack of information on the pathogen and a standard test for evaluating plant germplasm. Bacteria producing a fluorescent pigment were isolated on Kings B agar from alfalfa with symptoms of bacterial stem blight from near Cheyenne, WY. The strain ALF3 was tentatively identified as Pseudomonas syringae pv. syringae based on 16S rDNA sequence and PCR amplification of syrB for lipodepsinonapeptide toxin production. Multilocus sequence analysis indicated that ALF3 falls within a clade containing strains of P. syringae pv. syringae with closest affinity to FF5 from pear. Comparison of a draft whole-genome sequence of ALF3 further confirmed that ALF3 most closely resembles FF5 (~96% sequence identity) and P. syringae pv. aptata DSM50252 from beet. Approximately 60 genes were unique to ALF3, ...

AU - Greco, M.. AU - Lops, R.. AU - Graniti, A.. PY - 1999/11. Y1 - 1999/11. N2 - Several strains of plant pathogenic Pseudomonas are known to produce phytotoxic lipodepsipeptides (syringomycin, syringopeptins and related compounds) in vitro. However, detection of these compounds in organic extracts from diseased plant tissues has been attempted by chromatographic methods for syringomycin only. A macromolecular derivative of syringopeptins (KLH-SP(25A+B)) was used to raise polyclonal antibodies in rabbit. The antiserum was able to recognize free syringopeptins (SP22 and SP25) with an estimated detection limit of 0.05 μg per well in the indirect ELISA, and 0.01 μg per well in the competitive ELISA.

TY - THES. T1 - Genetic aspects of resistance to Pseudomonas solanacearum E.F. Smith in potato. AU - Tung, P.X.. N1 - WU thesis 1506 Proefschrift Wageningen. PY - 1992. Y1 - 1992. N2 - ,TT,The genetic control of resistance toPseudomonas s,TT,olanacearum in potato is complex and may involve both genes with major effects and genes with minor effects. However, no evidence of a gene-for-gene relationship between the host and the pathogen has been as yet documented. Strain specificity in the potato-P. solanacearum pathosystem is of the polygenic quantitative type and is probably a reflection of differential adaptation of host genotype and pathogen genotype to environments. Thus the resistance is chacterized by strong host x pathogen x environment interaction and tends to break down whenever faced with environmental conditions the host is not well adapted to. Expression of the resistance is heavily dependent on the adaptive potential of the carrier host genotype to a particular environment. Under heat ...
Bacteria that inhabit the rhizosphere of agricultural crops can have a beneficial effect on crop growth. One such mechanism is the microbial-driven solubilisation and remineralisation of complex forms of phosphorus (P). It is known that bacteria secrete various phosphatases in response to low P conditions. However, our understanding of their global proteomic response to P stress is limited. Here, exoproteomic analysis of Pseudomonas putida BIRD-1 (BIRD-1), Pseudomonas fluorescens SBW25 and Pseudomonas stutzeri DSM4166 was performed in unison with whole-cell proteomic analysis of BIRD-1 grown under phosphate (Pi) replete and Pi deplete conditions. Comparative exoproteomics revealed marked heterogeneity in the exoproteomes of each Pseudomonas strain in response to Pi depletion. In addition to well-characterised members of the PHO regulon such as alkaline phosphatases, several proteins, previously not associated with the response to Pi depletion, were also identified. These included putative ...
ADP-ribosylation of proteins occurs in many eukaryotes, and it is also the mechanism of action of a growing number of important bacterial toxins. To date, however, there is only one well-characterized ADP-ribosylation system where the ADP-ribosyltransferase and the substrate protein are both bacterial in origin, namely within the nitrogen-fixing bacterium Rhodospirillum rubrum. The present paper demonstrates the endogenous ADP-ribosylation of two proteins of Mr 32,000 and 20,000 within Pseudomonas maltophilia, a Gram-negative aerobe. The proteins have been partially purified: two apparently separate species of modified protein can be separated by ion-exchange chromatography and gel filtration (V0 and Mr 158,000 - Vi). The substrate protein(s) either has, or is co-eluted with, NAD+ glycohydrolase activity. The modification is mono-ADP-ribosyl in nature. The linkage between the acceptor amino acid and the ADP-ribose moiety is alkali-labile and stable to hydroxylamine, possibly indicating an ...

Pseudomonas syringae pv. DC3000 is a gram-negative bacterium that infects the model plant Arabidopsis thaliana. Pathogenicity is achieved via secretion of effector proteins into the host cytoplasm through a Type III Secretion System (T3SS). In Ps. DC3000 the T3SS (and associated effector proteins) are dependent on HrpL for their transcription. hrpL transcription is sigma54-dependent and requires two co-dependent enhancer binding proteins, HrpR and HrpS (HrpRS), for activation. HrpRS are regulated by two hrpL-dependent proteins, HrpV and HrpG, where HrpV negatively affects HrpRS activity and HrpG relieves this repression. Here the mechanism of HrpV and HrpGs action on HrpRS activity was tested in vivo and in vitro; and the molecular determinants of HrpV and HrpG functionality were characterised by in silico and mutational analysis. Whole-gene deletion mutants of hrpV and hrpG in Ps. DC3000 revealed complications associated with inserting marker cassettes in transcriptionally-antagonistic ...
