In the absence of ATP, supercoiled DNA is relaxed by DNA gyrase.

Microbial and chemical transformations of some 12,13-epoxytrichothec-9,10-enes. (1/991)

Resting cells of Streptomyces griseus, Mucor mucedo, and a growing culture of Acinetobacter calcoaceticus when mixed with compounds related to 12,13-epoxytrichothec-9-ene-4beta,15-diacetoxy-3alpha-ol(anguidine) produced a series of derivatives that were either partially hydrolyzed or selectively acylated. These derivatives showed marked differences in activities as assayed by antifungal and tissue culture cytotoxicity tests.  (+info)

Effect of desiccation on the ultrastructural appearances of Acinetobacter baumannii and Acinetobacter lwoffii. (2/991)

An Acinetobacter baumannii isolate survived desiccation beyond 30 days and an Acinetobacter lwoffii isolate up to 21 days. For both species, desiccation resulted in a significant increase in the proportion of round cells (A baumannii, 40% to 80%; A lwoffii, 51% to 63%) and a significant decrease in rod shaped cells (A baumannii, 58% to 13%; A lwoffii, 46% to 34%). Electronmicroscopic examination showed that there was also a corresponding significant increase in the cell wall thickness (A baumannii, up to 53%; A lwoffii, up to 26%). Desiccated A baumannii cells became more electron-dense and had significantly thicker cell walls (x1.3) than those of A lwoffii. Cell wall structures of A baumannii strains with different abilities to resist desiccation deserve further study.  (+info)

Acinetobacter bacteremia in Hong Kong: prospective study and review. (3/991)

The epidemiological characteristics of 18 patients with acinetobacter bacteremia were analyzed. Patients (mean age, 55.5 years) developed bacteremia after an average of 14.1 days of hospitalization. Fifteen of 16 patients survived bacteremia caused by Acinetobacter baumannii. Cultures of blood from the remaining two patients yielded Acinetobacter lwoffii. Most patients (78%) resided in the general ward, while four patients (22%) were under intensive care. Genotyping by arbitrarily primed polymerase chain reaction analysis and the temporal sequence of isolation were more useful than phenotyping by antimicrobial susceptibility in the determination of the source of bacteremia, and the intravascular catheter was the leading infection source (39% of cases). The possibility of an association of glucose with the pathogenesis of acinetobacter infection was raised.  (+info)

Risk factors for nosocomial bloodstream infections due to Acinetobacter baumannii: a case-control study of adult burn patients. (4/991)

Risk factors for Acinetobacter baumannii bloodstream infection (BSI) were studied in patients with severe thermal injury in a burn intensive care unit where A. baumannii was endemic. Of 367 patients hospitalized for severe thermal injury during the study period, 29 patients with nosocomial A. baumannii BSI were identified (attack rate, 7.9%). Cases were compared with 58 matched controls without A. baumannii BSI. The overall mortality rate was 31% among cases and 14% among controls; only two deaths (7%) were considered directly related to A. baumannii BSI. Molecular typing of A. baumannii blood isolates by means of randomly amplified polymorphic DNA analysis and pulsed-field gel electrophoresis revealed the presence of three different strain types. Multivariate analysis showed that female gender (P = .027), total body surface area burn of > 50% (P = .016), prior nosocomial colonization with A. baumannii at a distant site (P = .0002), and use of hydrotherapy (P = .037) were independently associated with the acquisition of A. baumannii BSI in burn patients. These data underscore the need for effective infection control measures for this emerging nosocomial problem.  (+info)

Phylogenetic structures of the genus Acinetobacter based on gyrB sequences: comparison with the grouping by DNA-DNA hybridization. (5/991)

The phylogenetic relationships of 49 Acinetobacter strains, 46 of which have previously been classified into 18 genomic species by DNA-DNA hybridization studies, were investigated using the nucleotide sequence of gyrB, the structural gene for the DNA gyrase B subunit. The phylogenetic tree showed linkages between genomic species 1 (Acinetobacter calcoaceticus), 2 (Acinetobacter baumannii), 3 and TU13; genomic species 6, BJ15, BJ16 and BJ17; genomic species 5, BJ13 (synonym of TU14) and BJ14; genomic species 7 (Acinetobacter johnsonii), 10 and 11; and genomic species 8 and 9. The phylogenetic grouping of Acinetobacter strains based on gyrB genes was almost congruent with that based on DNA-DNA hybridization studies. Consequently, gyrB sequence comparison can be used to resolve the taxonomic positions of bacterial strains at the level of genomic species. However, minor discrepancies existed in the grouping of strains of genomic species 8, 9 and BJ17. The phylogenetic tree for these strains was reconstructed from the sequence of rpoD, the structural gene for the RNA polymerase sigma 70 factor. The latter tree was 100% congruent with the grouping based on DNA-DNA hybridization. The reliability of DNA-DNA hybridization may be superior to that of sequence comparison of a single protein-encoding gene in resolving closely related organisms since the former method measures the homologies between the nucleotide sequences of total genomic DNAs. Three strains that have not been characterized previously by DNA-DNA hybridization seem to belong to two new genomic species, one including strain ATCC 33308 and the other including strains ATCC 31012 and MBIC 1332.  (+info)

Efficacy of sulbactam alone and in combination with ampicillin in nosocomial infections caused by multiresistant Acinetobacter baumannii. (6/991)

From March 1995 to March 1997, sulbactam was prospectively evaluated in patients with non-life-threatening multiresistant Acinetobacter baumannii infections. During this period, 47 patients were treated with sulbactam; of them, five were excluded because they had received < or =48 h of sulbactam therapy. A total of 42 patients, 27 males and 15 females with a mean age of 60+/-15 years, were finally evaluated. Infections were as follows: surgical wound, 19; tracheobronchitis, 12; urinary tract, 7; catheter-related bacteraemia, 2; and pneumonia, 2. Eighteen patients received intravenous sulbactam alone (1 g every 8 h) and 24 patients received intravenous sulbactam/ampicillin (1 g:2 g every 8 h) with no major adverse effects. Of the 42 patients, 39 improved or were cured and showed A. baumannii eradication and one patient had persistence of wound infection after 8 days of sulbactam/ampicillin requiring surgical debridement. Two patients died after 3 days of therapy (one of the deaths was attributable to A. baumannii infection). The in-vitro activity of the sulbactam/ampicillin combination was by virtue of the antimicrobial activity exhibited by sulbactam. Killing curves showed that sulbactam was bacteriostatic; no synergy was observed between ampicillin and sulbactam. Our results indicate that sulbactam may prove effective for non-life-threatening A. baumannii infections. Its role in the treatment of severe infections is unknown. However, the current formulation of sulbactam alone may allow its use at higher doses and provide new potential synergic combinations, particularly for those infections by A. baumannii resistant to imipenem.  (+info)

Engineering a chimeric pyrroloquinoline quinone glucose dehydrogenase: improvement of EDTA tolerance, thermal stability and substrate specificity. (7/991)

An engineered Escherichia coli PQQ glucose dehydrogenase (PQQGDH) with improved enzymatic characteristics was constructed by substituting and combining the gene-encoding protein regions responsible for EDTA tolerance, thermal stability and substrate specificity. The protein region responsible for complete EDTA tolerance in Acinetobacter calcoaceticus, which is recognized as the indicator of high stability in co-factor binding, was elucidated. The region is located between 32 and 59% from the N-terminus of A. calcoaceticus PQQGDH(A27 region) and also corresponds to the same position from 32 to 59% from the N-terminus in E. coli PQQGDH, though E. coli PQQGDH is EDTA sensitive. We previously reported that the C-terminal 3% region of A. calcoaceticus (A3 region) played an important role in the increase of thermal stability, and that His775Asn substitution in E. coli PQQGDH resulted in an increase in the substrate specificity of E. coli PQQGDH towards glucose. Based on these findings, chimeric and/or mutated PQQGDHs, E97A3 H775N, E32A27E41 H782N, E32A27E38A3 and E32A27E38A3 H782N were constructed to investigate the compatibility of two protein regions and one amino acid substitution. His775 substitution to Asn corresponded to His782 substitution to Asn (H782N) in chimeric enzymes harbouring the A27 region. Since all the chimeric PQQGDHs harbouring the A27 region were EDTA tolerant, the A27 region was found to be compatible with the other region and substituted amino acid responsible for the improvement of enzymatic properties. The contribution of the A3 region to thermal stability complemented the decrease in the thermal stability due to the His775 or His782 substitution to Asn. E32A27E38A3 H782N, which harbours all the above mentioned three regions, showed improved EDTA tolerance, thermal stability and substrate specificity. These results suggested a strategy for the construction of a semi-artificial enzyme by substituting and combining the gene-encoding protein regions responsible for the improvement of enzyme characteristics. The characteristics of constructed chimeric PQQGDH are discussed based on the predicted model, beta-propeller structure.  (+info)

On the binding of ATP to the autophosphorylating protein, Ptk, of the bacterium Acinetobacter johnsonii. (8/991)

The autophosphorylating protein, Ptk, of the bacterium Acinetobacter johnsonii was overproduced, purified to homogeneity and assayed for ATP binding by using the nucleotide analog 5'-p-fluorosulfonylbenzoyl adenosine. The ATP binding site of this bacterial autophosphorylating protein was found to be different from that generally used by eukaryotic protein kinases. It consists of two amino acid sequences that closely resemble the Walker motifs A and B. This observation was confirmed by site-directed mutagenesis experiments which showed, in addition, that the ATP molecule bound to these motifs is effectively employed by the bacterial protein to autophosphorylate on tyrosine. It is concluded that even though the overall autophosphorylation reaction is similar in eukaryotic and prokaryotic proteins, the mechanism involved is likely different.  (+info)

The Acinetobacter radioresistens strain was isolated in our laboratories from an activated sludge pilot plant. It is able to grow in presence of either phenol or benzoate as the sole carbon and energy source, metabolizing them via the ortho pathway. A proteomic approach to the study of the regulation of these catabolic pathways showed that the expression of most of the catabolic enzymes is modulated by the growth substrate (1, 2). Moreover, "satellite" proteins were identified (porins, chaperonins), specifically induced by aromatics and probably involved in the uptake of these molecules and in the physiological cell response to their presence. In the present research these results have been extended by a more precise kinetic analysis of the bacterial growth on either an aromatic (phenol or benzoate) or a non-aromatic (acetate) carbon source. From these experiments it can be seen that cultures grown in presence of phenol or acetate show similar specific growth rates (=0.769 and 0.766 h-1 ...

Biosurfactant producers are crucial for incremental oil production in microbial enhanced oil recovery (MEOR) processes. The isolation of biosurfactant-producing bacteria from oil reservoirs is important because they are considered suitable for the extreme conditions of the reservoir. In this work, a novel biosurfactant-producing strain Acinetobacter junii BD was isolated from a reservoir to reduce surface tension and emulsify crude oil. The biosurfactants produced by the strain were purified and then identified via electrospray ionization-Fourier transform ion cyclotron resonance mass spectrometry (ESI FT-ICR-MS). The biosurfactants generated by the strain were concluded to be rhamnolipids, the dominant rhamnolipids were C26H48O9, C28H52O9 and C32H58O13. The optimal carbon source and nitrogen source for biomass and biosurfactant production were NaNO3 and soybean oil. The results showed that the content of acid components increased with the progress of crude oil biodegradation. A glass micromodel test

Ver más] As a part of a nationwide study in Spain, 15 clinical isolates of Acinetobacter genomic species 3 (AG3) were analyzed. The main objective of the study was to characterize the ampC genes from these isolates and to determine their involvement in B-lactam resistance in AG3. The 15 AG3 isolates showed different profiles of resistance to ampicillin (range of MICs, 12 to ,256 μg/ml). Nucleotide sequencing of the 15 ampC genes yielded 12 new AmpC enzymes (ADC-12 to ADC-23). The 12 AG3 enzymes showed 93.7 to 96.1% amino acid identity with respect to the AmpC enzyme from Acinetobacter baumannii (ADC-1 enzyme). Eight out of fifteen ampC genes were expressed in Escherichia coli cells under the control of a common promoter, and with the exception of one isolate (isolate 65, which showed lower B-lactam MICs), significant differences in overall B-lactam MICs for E. coli cells expressing AG3 ampC genes were not revealed. No significant differences in ampC gene expression in AG3 clinical isolates ...
Optimum conditions for the activity of the new DNA methylase in cell lysate were determined. Methylation of DNAs of bacteriophages λ and T7 and plasmid pBR322 (dcm+) in the 5′-Cm5CWGG-3′ region blocked M.AjnI activity. The specificity of M.AjnI was determined using λ DNA methylated by this enzyme as well as computer modeling and data on the sensitivity of restriction endonucleases Mval, HinfI, and BstMAI to methylation.
Essential cell division protein that forms a contractile ring structure (Z ring) at the future cell division site. The regulation of the ring assembly controls the timing and the location of cell division. One of the functions of the FtsZ ring is to recruit other cell division proteins to the septum to produce a new cell wall between the dividing cells. Binds GTP and shows GTPase activity.
The SOS response to DNA damage that induces up to 10% of the prokaryotic genome requires RecA action to relieve LexA transcriptional repression. In Acinetobacter species, which lack LexA, the error-prone polymerase accessory UmuDAb is instead required for ddrR induction after DNA damage, suggesting it might be a LexA analog. RNA-Seq experiments defined the DNA damage transcriptome (mitomycin C-induced) of wild type, recA and umuDAb mutant strains of both A. baylyi ADP1 and A. baumannii ATCC 17978. Of the typical SOS response genes, few were differentially regulated in these species; many were repressed or absent.

The World Health Organization has just released its list of the 12 bacteria that pose the greatest risk to humanitys existence, stating that new antibiotics are "urgently needed" to counter them. WHO held a press conference recently to unveil the list of the most dangerous "superbugs," which are resistant to most antibiotics making them difficult or nearly impossible to treat.. The bacteria Acinetobacter baumannii topped the list. This disease can result in pneumonia, blood infections, and more. It affects people with compromised immune systems, and it attacks organ systems with a high fluid content, like the respiratory or urinary tract. ...

Acinetobacter calcoaceticus is a bacterial species of the genus Acinetobacter. It is a nonmotile, gram negative coccobacillus. It grows under aerobic conditions, is catalase positive and oxidase negative. It is part of the normal human intestinal flora. Together with A. baumannii, it is referred to as the A. calcoaceticus-A. baumannii complex, which is relatively simple to identify based on the beforementioned phenotypic characteristics. To identify other Acinetobacter species genotyping is required. A. calcoaceticus is a soil bacterium. It has been shown to be prevalent in the tiger mosquito Aedes albopictus microflora. Phloroglucinol carboxylic acid is a degradation product excreted by A. calcoaceticus grown on (+)-catechin as the sole source of carbon. A. calcoaceticus can be pathogenic and cause an opportunistic infection in patients with multiple underlying diseases. A. calcoaceticus can be used as an alternative to A. baumannii in the laboratory setting. The interchangeability of the two ...
Wax ester synthases (WSs) can synthesize wax esters from alcohols and fatty acyl coenzyme A thioesters. The knowledge of the preferred substrates for each WS allows the use of yeast cells for the production of wax esters that are high-value materials and can be used in a variety of industrial applications. The products of WSs include fatty acid ethyl esters, which can be directly used as biodiesel. Here, heterologous WSs derived from five different organisms were successfully expressed and evaluated for their substrate preference in Saccharomyces cerevisiae. We investigated the potential of the different WSs for biodiesel (that is, fatty acid ethyl esters) production in S. cerevisiae. All investigated WSs, from Acinetobacter baylyi ADP1, Marinobacter hydrocarbonoclasticus DSM 8798, Rhodococcus opacus PD630, Mus musculus C57BL/6 and Psychrobacter arcticus 273-4, have different substrate specificities, but they can all lead to the formation of biodiesel. The best biodiesel producing strain was found to be

Columbus, OH - November 2016. The bacteria Acinetobacter baumannii is a widely-reported cause of healthcare-associated infections, particularly in adult intensive care units in developing countries. But a retrospective study of isolated cases at Nationwide Childrens Hospital found that Acinetobacter pittii recently emerged as the more common cause of infection among patients there.. At a time when hospitals are trying to eliminate all possible harm, the discovery drives home the importance of being vigilant and of taking advantage of the latest genotyping techniques, the researchers say.. As we try to characterize hospital acquired infections, its important to do good speciation of the bacteria, says Benjamin Kopp, MD, a pulmonologist and principal investigator in the Center for Microbial Pathogenesis at The Research Institute at Nationwide Childrens, and senior author of the study. The Acinetobacter complex contains many different species that can act differently, so you cant really ...
I am interested in DNA repair mechanisms and recombination. These processes are essential for the protection of organisms from DNA-damaging agents such as ultraviolet light and chemical mutagens. These mechanisms also contribute to the evolution of new traits. Projects in my lab involve using genetic and molecular techniques to study DNA repair and recombination in the bacteria Escherichia coli and Acinetobacter baylyi. In E. coli, DNA damage causes the induction of over 20 genes and this is termed the SOS response. Although the SOS system has served as a model for understanding DNA repair and recombination in other systems such as yeast, plants and humans, there is still much that we dont understand about the SOS response in E. coli. For example, we have not yet identified the precise inducing signal of the SOS response or the biological functions of many of the SOS gene products. It is not yet clear whether A. baylyi exhibits an E. coli-like SOS response. Characterization of DNA repair and ...

By Stewart MacInnis. Spectrum Volume 18 Issue 21 - February 22, 1996 John L. Johnson, whose pioneering research on differential Bacteroides species won him international recognition as a microbiologist, died last Friday (Feb. 16) at his Blacksburg home after a long illness. He was 59.. "He was an outstanding scientist, he was an excellent teacher, and he really cared about his work," said W.E.C. Moore, a friend and former colleague of Johnsons. "The world lost a top scientist in microbiology.". Moore, then head of the anaerobe laboratory, brought Johnson to Virginia Tech from his post-doctoral studies at the University of Washington-Seattle in 1968. "John did his best work here," Moore said.. That work earned Johnson the 1980 Bergeys Manual Trust Award, one of the most prestigious international awards given in his field. The Pasteur Institute of Paris named a bacterial species for Johnson, Acinetobacter johnsonii. That, Moore said, is a sign of exceptional respect and an indication of the ...
SUMMARY Steel and Cowan (1964) designated Schaub's Biol. 1 as the type strain for Bacterium anitratum Schaub and Hauber 1948. However, this strain was not included among those originally studied by Schaub and Hauber (1948) and cannot be recognized (Rule 9d, Note b, Intl. Code of Nomenclature of Bacteria). One of the original strains used by Schaub and Hauber (Schaub 81, American Type Culture Collection (ATCC) 19606, RH 2208) is here designated as the type for B. anitratum Schaub and Hauber 1948. The morphology, physiology, and per cent guanine plus cytosine of strain 81 are described and more than sixty characters of the strain recorded. The characteristics of strain 81 were found to be in good agreement with those given in the original description by Schaub and Hauber (1948).

As part of the SENTRY Antimicrobial Surveillance Program, a total of 1078 Acinetobacter species and 842 Stenotrophomonas maltophilia isolates were collected between January 1997 and December 1999 from 5 geographic regions (Canada, the United States, Latin America, Europe, and the Asia-Pacific). The frequency of infections (by geographic region and body site), including those due to imipenem-resistant Acinetobacter species and trimethoprim-sulfamethoxazole (TMP-SMZ)-resistant S. maltophilia, was evaluated. The possibility of seasonal variations in bloodstream infections caused by Acinetobacter species was studied, as was the activity of several therapeutic antimicrobials against all strains. Acinetobacter species and S. maltophilia were most frequently associated with pulmonary infections, independent of the region evaluated. In contrast, patterns of antimicrobial resistance markedly varied among distinct geographic regions, especially for nosocomial isolates. Although the carbapenems were the ...
Acinetobacter calcoaceticus BD413 accumulates wax esters and triacylglycerol under conditions of mineral nutrient limitation. Nitrosoguanidine-induced mutants of strain BD413 were isolated that failed to accumulate wax esters under nitrogen-limited growth conditions. One of the mutants, Wow15 (without wax), accumulated wax when grown in the presence of cis-11-hexadecenal and hexadecanol but not hexadecane or hexadecanoic acid. This suggested that the mutation may have inactivated a gene encoding either an acyl-acyl carrier protein or acyl-coenzyme A (CoA) reductase. The Wow15 mutant was complemented with a cosmid genomic library prepared from wild-type A. calcoaceticus BD413. The complementary region was localized to a single gene (acr1) encoding a protein of 32,468 Da that is 44% identical over a region of 264 amino acids to a product of unknown function encoded by an open reading frame associated with mycolic acid synthesis in Mycobacterium tuberculosis H37Ra.

Acinetobacter, belonging to γ-proteobacteria, are gram-negative strictly aerobic, non-motile, non-fermentative and oxidase-negative bacteria. The classification of the genus Acinetobacter contains over 50 species [1]. Acinetobacter spp. were considered for decades as saprophytic environmental microorganisms. However, recently, they have increasingly been implicated in various types of infections, mainly nosocomial infections in fragilized patients in intensive care units, hence adding the hospital to the list of their favorite environments. A major trait of their pathogenicity is their high and broad array of antibiotic resistance. The often multi-drug resistance (MDR) Acinetobacter baumannii is the major species in the genus involved in recent nosocomial infections. In contrast to A. baumannii that is mainly found in the hospital environment, other species of the Acinetobacter genus are isolated from the soil, water, and animals [2]. Many environmental Acinetobacter spp. are able to metabolize ...
Acinetobacter spp. are a diverse group of Gram-negative bacteria frequently implicated in nosocomial infections. Genotypic methods have been instrumental in studying Acinetobacter, but few offer high resolution, rapid turnaround time, technical ease and high inter-laboratory reproducibility, which has hampered understanding of disease incidence, transmission patterns and diversity within this genus. Here, we further evaluated multilocus PCR electrospray ionization/ mass spectrometry (PCR/ESI-MS), a method that is simple and robust, and provides both species characterization and strain-level resolution of Acinetobacter spp. on a single platform. We examined 125 Acinetobacter isolates from 21 hospitals, laboratories and medical centres spanning four counties in Arizona, USA, using PCR/ESI-MS. We compared PCR/ESI-MS with an in-house amplified fragment length polymorphism (AFLP) genotyping scheme. PCR/ESI-MS demonstrated that Acinetobacter spp. from Arizonan hospitals had similar species and strain
Given the growing interest in the production of new and low cost bioemulsifiers, the rice and wheat bran and straw were investigated in this study for the production of bioemulsifier by Lactobacillus plantarum subsp. plantarum PTCC 1896 (probiotic). The strain produced bioemulsifier only in the rice bran hydrolysate medium. The bioemulsifier amount reached around 0.7 g L-1 for 72 hours of fermentation. The new biomolecule was extracted, purified, and its structural and thermal properties were evaluated. The functional groups and the structure of the molecule were revealed by GPC, FT-IR, 1HNMR and 13CNMR techniques. The bioemulsifier was a water soluble extracellular high molecular weight (|107 Da) α-glucan (81.74%) bound with protein (18.18%). Thermal behavior was studied using DSC and TG analysis. Thermal analysis showed the bioemulsifier broke down above 211.74°C, and the melting point was 182.0°C with the enthalpy value of 101.7 J g-1. These results might provide incentives for the industrial

Bacterial infections due to Acinetobacter species are typically encountered in health care settings and can be particularly difficult to treat due to the propensity of the organism to incorporate multiple antibiotic resistance mechanisms. Hospital outbreaks of multidrug-resistant Acinetobacter infections have been reported. A wide range of infections are possible with this organism, including bloodstream infections, pneumonia (occasionally even community-acquired pneumonia), urinary tract infections, and wound infections (wound infection in soldiers after traumatic injury have been reported ...

Acinetobacter baumannii bacteria, coloured scanning electron micrograph (SEM). This bacterium has developed resistance to a number of antibiotics and is increasingly seen in opportunistic infections in hospitals. It typically infects the lungs, leading to a form of pneumonia. It can develop resistance to antibiotics even as they are being used to treat an infection. Because of this, and because it is generally found in weakened patients, the mortality rate for infections with A. baumannii is high. In healthy individuals, however, it is a normal part of the skin flora. Magnification: x11,000 when printed 10 centimetres wide. - Stock Image B220/1513

In laboratory experiments, the antifouling (AF) properties of zinc oxide (ZnO) nanorod coatings were investigated using the marine bacterium Acinetobacter sp. AZ4C, larvae of the bryozoan Bugula neritina and the microalga Tetraselmis sp. ZnO nanorod coatings were fabricated on microscope glass substrata by a simple hydrothermal technique using two different molar concentrations (5 and 10 mM) of zinc precursors. These coatings were tested for 5 h under artificial sunlight (1060 W m(-2) or 530 W m(-2)) and in the dark (no irradiation). In the presence of light, both the ZnO nanorod coatings significantly reduced the density of Acinetobacter sp. AZ4C and Tetraselmis sp. in comparison to the control (microscope glass substratum without a ZnO coating). High mortality and low settlement of B. neritina larvae was observed on ZnO nanorod coatings subjected to light irradiation. In darkness, neither mortality nor enhanced settlement of larvae was observed. Larvae of B. neritina were not affected by Zn2+ ...
Prompt detection of metallo-beta-lactamase (MBL) producing isolates is necessary to prevent their dissemination. Frequency of MBLs producing strains among multidrug resistant (MDR) Acinetobacter species and Pseudomonas aeruginosa was evaluated in critical care Patients using imipenem-EDTA disk method. One hundred MDR Acinetobacter spp. and 42 Pseudomonas aeruginosa were checked for MBL production, from January to June 2001. MBL was produced by 96.6 % of imipenem-resistant Acinetobacter isolates, whereas 100% imipenem-resistant Pseudomonas aeroginosa isolates were MBL producers. Carbapenem resistance in MDR Acinetobacter spp. and Pseudomonas aeruginosa isolates in this study was due to MBLs. This calls for strict infection control measures to prevent further dissemination.

In a 3-month period, three men who had worked for 5 to 19 years as welders or grinders of steel castings in a foundry acquired pneumonia caused by Acinetobacter calcoaceticus variety anitratus serotype 7J. Two of the men died, and postmortem examination showed mixed-dust pneumoconiosis with iron particles in the lungs. A. calcoaceticus variety anitratus serotype 7J was isolated from the air in the foundry but the source was not found. The prevalence of antibody titers of 64 or greater to the 7J strain was significantly higher among foundry workers (15%) than among community controls (2%) (p , 0.01). Sampling showed that the concentrations of total and metallic particles (especially iron) and of free silica in air inhaled by welders and grinders at the foundry frequently exceeded acceptable levels. These findings suggest that chronic exposure to such particles may increase susceptibility to infection by this organism, which rarely affects healthy people. ...
Ochratoxin A (OTA) is a mycotoxin with a main nephrotoxic activity contaminating several foodstuffs. In the present report, five soil samples collected from OTA-contaminated vineyards were screened to isolate microorganisms able to biodegrade OTA. When cultivated in OTA-supplemented medium, OTA was converted in OTα by 225 bacterial isolates. To reveal clonal relationships between isolates, molecular typing by using an automated rep-PCR system was carried out, thus showing the presence of 27 different strains (rep-PCR profiles). The 16S-rRNA gene sequence analysis of an isolate representative of each rep-PCR profiles indicated that they belonged to five bacterial genera, namely Pseudomonas, Leclercia, Pantoea, Enterobacter, and Acinetobacter. However, further evaluation of OTA-degrading activity by the 27 strains revealed that only Acinetobacter calcoaceticus strain 396.1 and Acinetobacter sp. strain neg1, consistently conserved the above property; their further characterization showed that they were

Five methods for assaying bacterial surface hydrophobicity, namely, bacterial adherence to hydrocarbons, salt aggregation, hydrophobic interaction chromatography, adhesion to polystyrene and latex particle agglutination were used to compare the hydrophobic surface properties of Escherichia coli, Acinetobacter calcoaceticus, Staphylococcus aureus and Streptococcus mitis. Two strains of A. calcoaceticus, including RAG-1, gave strong positive results by all five methods. S. mitis gave weak or negative results by all methods. The results for the other bacteria varied with the method. We conclude that reliance on one method for such tests is inadequate ...

Carbapenem resistance in A. baumannii is most often associated with class D β-lactamases (OXA-23-like, OXA-40-like and OXA-58-like) and MBLs. OXA-type carbapenemases are predominant in A. baumannii, particularly in worldwide outbreaks of OXA-23 [24]. The molecular analysis of the isolates tested in this study revealed that 14 strains (51.8 %) carried the blaOXA-23-like gene and that two strains carried a blaOXA-24-like gene. All of the strains had a blaOXA-51-like gene, and four strains had a blaOXA-58 gene. In this study, the OXA-58 isolates presented lower MIC values for meropenem than OXA-23-like-positive isolates, which systematically exhibited higher MIC values (Table 1). The isolates with non-acquired OXA genes displayed a marked variation and included some carbapenem-resistant genes. Naturally occurring OXA carbapenemases, such as OXA-51-like enzymes (e.g., OXA 64-66, OXA 68-71, OXA 78-80, OXA-82, OXA-86, OXA-92 and OXA104-112), have been identified in A. baumannii isolates worldwide. In ...
Acinetobacter baumannii causes severe nosocomial infections such as pneumonia, meningitis and sepsis with high mortality rates. This organism represents an increasing danger for immunocompromised adults, especially since there are an increasing number of resistances against antibiotics. Until now, scientific investigation was mainly focused on taxonomy and antibiotic resistance mechanisms. The goal of this project was to analyse the interaction between clinical strains of Acinetobacter baumannii and human cells in order to address the molecular mechanisms causing pathogenicity. Adherence is the first step in colonization of human tissue, and therefore a key event in pathogenesis. To demonstrate the adhesion of bacteria to human cells, a colony counting assay has been established. These experiments used the the type strain of A. baumannii ATCC 19606, as well as clinical isolates. All A. baumannii strains investigated showed adhesion to the lung epithelial cells A549, but the adhesion capacity was ...

Hospital-acquired infections due to Acinetobacter baumannii have become problematic because of high rates of drug resistance. A. baumannii is usually harmless, but it causes sepsis resulting in a high mortality rate in compromised hosts. Therefore, we must consider its interaction with host cells to understand diseases resulting from A. baumannii infection. Neutrophils play a critical role in infective protection against the extracellular growth of bacteria. However, their interactions with A. baumannii remain largely unknown. Recently, a new biological defense mechanism called neutrophil extracellular traps (NETs) has been attracting attention. In the present study, we investigated the responsiveness of human neutrophils to A. baumannii focusing on NET formation. The results demonstrated that infective protection against Pseudomonas aeruginosa via NETs formation was observed, but for A. baumannii NETs formation did not occur. It seems that the innate infective protection against A. baumannii ...

Acinetobacter baumannii has emerged as an important nosocomial pathogen due to its increasing resistance to most, if not all, antibiotics in clinical use. We recently reported the occurrence of extensive-drug resistant (XDR) A. baumannii isolates in a Malaysian tertiary hospital. The genome of one of these XDR isolates, A. baumannii AC12, was completely sequenced and comparative genome analyses performed to elucidate the genetic basis of its antimicrobial resistance. The A. baumannii AC12 genome consists of a 3.8 Mbp circular chromosome and an 8,731 bp cryptic plasmid, pAC12. It belongs to the ST195 lineage and is most closely related to A. baumannii BJAB0715 as well as other strains of the International Clone III (IC-III) group. Two antibiotic resistance islands (RIs), designated AC12-RI1 and AC12-RI2, were found in the AC12 chromosome along with a 7 kb Tn1548::armA island, conferring resistance to aminoglycosides and macrolides. The 22.8 kb AC12-RI1 interrupts the comM gene and harbours the ...

Two methods of bioemulsifier separation were applied. The first method was performed according to the procedure described by others [5,8,11,18,19], in which growth the culture was filtered through a filter paper and later through a cellulose membrane. The cell-free medium was transferred to a separatory funnel and extracted with 500 ml of chloroform-methanol solution (2:1). The creamy precipitate formed between the aqueous and the organic phase was collected on cellulose filter and nitrogen stream dried. In the second method, the culture medium was stored at 4°C for 24 h to ensure cell sedimentation. The broth of nitrogen-limited culture on glycerol was separated from cells by centrifugation at 10000×g for 10 min. The resulting cell-free medium was then filtered through a 0.45 µm membrane (Millipore). Approximately 80 ml of the cell-free filtrate was transferred to a separatory funnel and supernatant was acidified to pH 2 with H2SO4 and extracted with 50 ml of ethyl acetate. The aqueous phase ...
A. baumannii the most clinically relevant of the bacteria tested, have a particular propensity for nosocomial transmission, due in part to their sustained survival on environmental surfaces as well as their multidrug resistance. The prevalence of infection with A. baumannii has increased significantly during the last decade. Moreover, A. baumannii have developed one of the most impressive patterns of antibiotic resistance ever observed. Therefore, rapid detection of A. baumannii in clinical samples could improve the targeted implementation of infection control measures and potentially aid the selection of empirical therapies for infected patients [3,5].. To culture A. baumannii isolated from clinical samples and to screen for carriers among intensive care unit patients, use of a selective enrichment medium is recommended. In recent years, a few previous reports about CHROMagar Acinetobacter® have been published with regard to multidrug resistant A. baumannii (MDRAB). Gordon et al. [6] reported ...

A key review article has been published in the Journal of Hospital Infection summarising the accumulating evidence that the status of the prior room occupant can influence the chances of the incoming occupant picking up an MDRO. The bottom line is that if you are admitted to a room previously occupied by a patient with an MDRO (including MRSA, VRE, C. difficile and Acinetobacter sp.), you are twice as likely to acquire that MDRO. The impact of these findings is clear: we need to improve standards of discharge disinfection to protect the incoming occupant. So how can we do this? There are several paths to follow towards the same end - and these are not mutually exclusive:. Improve the cleaning / disinfection process ...

Beggs, J.D.; Cook, A.M.; Fewson, C.A., 1976: Regulation of growth of Acinetobacter calcoaceticus NCIB8250 on benzyl alcohol in batch culture
Introduction: Acinetobacter baumannii is opportunistic in debilitated hospitalised patients. Because information from some South American countries was previously lacking, this study examined the emergence of multi-resistant A. baumannii in three hospitals in Cochabamba, Bolivia, from 2008 to 2009. Methodology: Multiplex PCR was used to identify the main resistance genes in 15 multi-resistant A. baumannii isolates. RT-PCR was used to measure gene expression. The genetic environment of these genes was also analysed by PCR amplification and sequencing. Minimum inhibitory concentrations were determined for key antibiotics and some were determined in the presence of an efflux pump inhibitor, 1-(1-napthylmethyl) piperazine. Results: Fourteen strains were found to be multi-resistant. Each strain was found to have the bla(OXA-58) gene with the ISAba3-like element upstream, responsible for over-expression of the latter and subsequent carbapenem resistance. Similarly, ISAba1, upstream of the bla(ADC) ...
The worldwide dissemination of multi drug resistant Acinetobacter baumannii strains has caused serious concern and high rate of mortality in recent decades that originate from limited effective antibiotics in the treatment of A. baumannii infections. Myxobacteria are Gram-negative bacteria that are important for their complex lifestyle and production of novel structurally secondary metabolites with diverse bioactivities. In this study, a total of 60 myxobacterial strains were purified by culturing and investigation of 130 soil samples. Secondary metabolite extracts of the selected strains were screened for antibacterial activity against multi-drug resistant (MDR) Acinetobacter baumannii. The most potent extracts derived from Stigmatella sp. UTMC 4081, Stigmatella sp. UTMC 4072, and Archangium sp. UTMC 4070 which were investigated by recording percentage of growth inhibition, MIC, MBC, and IC50 values. The results showed that the MIC value of extract No. 4072 was 2.5 μg/ml and its MBC value against A.
Nosocomial pathogens can be associated with a variety of infections, particularly in intensive care units (ICUs) and in immunocompromised patients. Usually these pathogens are resistant to multiple drugs and pose therapeutic challenges. Among these organisms, Acinetobacter baumannii is one of the most frequent being encountered in the clinical setting. Carbapenems are very useful to treat infections caused by these drug-resistant Gram-negative bacilli, but carbapenem resistance is increasing globally. Combination therapy is frequently given empirically for hospital-acquired infections in critically ill patients and is usually composed of an adequate beta-lactam and an aminoglycoside. The purpose of this study was to evaluate the in vitro activity of plazomicin against carbapenem-resistant Acinetobacter baumannii. Amikacin was used as a comparator. The activity of plazomicin in combination with several different antibiotics was tested by disk diffusion, the checkerboard method, and time-kill ...
This study reports the dissemination of multidrug-resistant (MDR) OXA-23-producing Acinetobacter baumannii clones in hospitals in Antananarivo, Madagascar. A total of 53 carbapenem-resistant A. baumannii isolates were obtained from September 2006 to March 2009 in five hospitals. These resistant strains represent 44% of all A. baumannii isolates. The double disk synergy test was performed to screen for production of metallo-beta-lactamases. Polymerase chain reaction (PCR) and DNA sequencing were performed for the detection of bla(AmpC), bla(OXA-51),bla(OXA-23), bla(OXA-24), bla(IMP), bla(VIM). The presence of the insertion sequence ISAba1 relative to bla OXA-23 and bla OXA-51 was assessed by PCR. Isolates were typed by Rep-PCR. All the isolates were MDR and produced the OXA-23 carbapenemase, which was confirmed by sequencing. PCR analysis for AmpC and OXA-51 gave positive results for all strains studied. No isolates produced metallo-beta-lactamases. In all isolates ISAba1 laid upstream of bla OXA-23. The
