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)

Overall, gram-negative bacterial infections are a significant public health concern, and proper diagnosis and treatment are essential to prevent complications and reduce the risk of transmission.

First-degree burns are the mildest form of burn and affect only the outer layer of the skin. They are characterized by redness, swelling, and pain but do not blister or scar. Examples of first-degree burns include sunburns and minor scalds from hot liquids.

Second-degree burns are more severe and affect both the outer and inner layers of the skin. They can cause blisters, redness, swelling, and pain, and may lead to infection. Second-degree burns can be further classified into two subtypes: partial thickness burns (where the skin is damaged but not completely destroyed) and full thickness burns (where the skin is completely destroyed).

Third-degree burns are the most severe and affect all layers of the skin and underlying tissues. They can cause charring of the skin, loss of function, and may lead to infection or even death.

There are several ways to treat burns, including:

1. Cooling the burn with cool water or a cold compress to reduce heat and prevent further damage.
2. Keeping the burn clean and dry to prevent infection.
3. Applying topical creams or ointments to help soothe and heal the burn.

Here are some key points to define sepsis:

1. Inflammatory response: Sepsis is characterized by an excessive and uncontrolled inflammatory response to an infection. This can lead to tissue damage and organ dysfunction.
2. Systemic symptoms: Patients with sepsis often have systemic symptoms such as fever, chills, rapid heart rate, and confusion. They may also experience nausea, vomiting, and diarrhea.
3. Organ dysfunction: Sepsis can cause dysfunction in multiple organs, including the lungs, kidneys, liver, and heart. This can lead to organ failure and death if not treated promptly.
4. Infection source: Sepsis is usually caused by a bacterial infection, but it can also be caused by fungal or viral infections. The infection can be localized or widespread, and it can affect different parts of the body.
5. Severe sepsis: Severe sepsis is a more severe form of sepsis that is characterized by severe organ dysfunction and a higher risk of death. Patients with severe sepsis may require intensive care unit (ICU) admission and mechanical ventilation.
6. Septic shock: Septic shock is a life-threatening condition that occurs when there is severe circulatory dysfunction due to sepsis. It is characterized by hypotension, vasopressor use, and organ failure.

Early recognition and treatment of sepsis are critical to preventing serious complications and improving outcomes. The Sepsis-3 definition is widely used in clinical practice to diagnose sepsis and severe sepsis.

Some common types of lung diseases include:

1. Asthma: A chronic condition characterized by inflammation and narrowing of the airways, leading to wheezing, coughing, and shortness of breath.
2. Chronic Obstructive Pulmonary Disease (COPD): A progressive condition that causes chronic inflammation and damage to the airways and lungs, making it difficult to breathe.
3. Pneumonia: An infection of the lungs that can be caused by bacteria, viruses, or fungi, leading to fever, chills, coughing, and difficulty breathing.
4. Bronchiectasis: A condition where the airways are damaged and widened, leading to chronic infections and inflammation.
5. Pulmonary Fibrosis: A condition where the lungs become scarred and stiff, making it difficult to breathe.
6. Lung Cancer: A malignant tumor that develops in the lungs, often caused by smoking or exposure to carcinogens.
7. Cystic Fibrosis: A genetic disorder that affects the respiratory and digestive systems, leading to chronic infections and inflammation in the lungs.
8. Tuberculosis (TB): An infectious disease caused by Mycobacterium Tuberculosis, which primarily affects the lungs but can also affect other parts of the body.
9. Pulmonary Embolism: A blockage in one of the arteries in the lungs, often caused by a blood clot that has traveled from another part of the body.
10. Sarcoidosis: An inflammatory disease that affects various organs in the body, including the lungs, leading to the formation of granulomas and scarring.

These are just a few examples of conditions that can affect the lungs and respiratory system. It's important to note that many of these conditions can be treated with medication, therapy, or surgery, but early detection is key to successful treatment outcomes.

The hallmark symptoms of bronchiectasis are chronic cough, recurrent respiratory tract infections, and excessive mucus production. These symptoms can significantly impact quality of life, and if left untreated, the disease can progress to severe respiratory failure and other complications such as pulmonary hypertension.

Bronchiectasis is most commonly caused by recurrent lower respiratory tract infections, such as those caused by Pneumocystis jirovecii (formerly known as Pneumocystis carinii) and Haemophilus influenzae type b (Hib). Other risk factors for developing bronchiectasis include a history of childhood respiratory infections, exposure to tobacco smoke, and underlying conditions such as cystic fibrosis or primary immunodeficiency disorders.

Diagnosis of bronchiectasis typically involves a combination of clinical evaluation, radiologic imaging (such as high-resolution computed tomography, or HRCT), and pulmonary function tests. Treatment options for bronchiectasis include antibiotics to manage infections, bronchodilators to improve lung function, and airway clearance techniques such as chest physical therapy and pulmonary rehabilitation. In severe cases, lung transplantation may be considered.

Preventive measures for bronchiectasis include prompt treatment of respiratory infections, avoiding exposure to environmental irritants such as tobacco smoke, and managing underlying conditions that increase the risk of developing the disease. Early diagnosis and aggressive management of bronchiectasis can help slow disease progression, improve quality of life, and reduce the risk of complications such as respiratory failure and lung cancer.

Symptoms of otitis externa may include:

* Ear pain or tenderness
* Redness and swelling of the ear canal
* Discharge or pus in the ear canal
* Itching or burning sensation in the ear canal
* Fever or chills
* Difficulty hearing or feeling as if the ear is clogged

Otitis externa can be diagnosed by a healthcare professional through a physical examination of the ear canal and may also involve a pus sample or imaging tests such as X-rays or CT scans to rule out other conditions. Treatment options for otitis externa may include antibiotics, anti-inflammatory medications, or topical creams or drops to reduce pain and inflammation. In severe cases, surgery may be necessary to remove any infected tissue or debris from the ear canal.

Prevention of otitis externa includes avoiding exposure to moisture, using earplugs when swimming or showering, and keeping the ears clean and dry. If you suspect you have otitis externa, it is important to seek medical attention promptly to prevent complications such as mastoiditis or meningitis.

However, an additional challenge remains in that ILs present in biomass hydrolysates are toxic to most microbial hosts, resulting in poor growth phenotypes. To address this issue, we applied an adaptive laboratory evolution (ALE) approach for tolerizingPseudomonas putidaKT2440, an industrially relevant bacterial host, to two low-cost ILs (triethanolammonium acetate [TEOH][OAc] and triethylammonium hydrogen sulfate [TEA][HS]). After continuous cultivations with gradually increased IL levels, we obtained evolved strains
