| nonfermenting gram-negative bacilli infections in a tertiary care hospital in kolar, karnataka. | aim: nonfermenting gram-negative bacilli (nfgnb), which are saprophytic in nature, have emerged as important healthcare-associated pathogens. they exhibit resistance not only to beta lactam and the other groups of antibiotics, but also to carbapenems. this study was undertaken to identify the nonfermenters isolated from various clinical samples, to assess their clinical significance, to know the type of healthcare-associated infections they caused, and to know their anti-microbial sensitivity pa ... | 2009 | 21938252 |
| Contemporary unconventional clinical use of co-trimoxazole. | Clin Microbiol Infect 2012; 18: 8-17 ABSTRACT: In the late 1960s, the combination of trimethoprim and sulphamethoxazole (co-trimoxazole) was introduced into clinical practice and used to treat many infectious diseases, such as urinary tract infections, respiratory infections, sexually transmitted diseases, Gram-negative sepsis, enteric infections and typhoid fever. Subsequently, co-trimoxazole was reported to be effective against numerous bacterial, fungal and protozoal pathogens, including Noca ... | 2012 | 21851485 |
| contribution of resistance-nodulation-division efflux pump operon smeu1-v-w-u2-x to multidrug resistance of stenotrophomonas maltophilia. | kj09c, a multidrug-resistant mutant of stenotrophomonas maltophilia kj, was generated by in vitro selection with chloramphenicol. the multidrug-resistant phenotype of kj09c was attributed to overexpression of a resistance nodulation division (rnd)-type efflux system encoded by an operon consisting of five genes: smeu1, smev, smew, smeu2, and smex. proteins encoded by smev, smew, and smex were similar to the membrane fusion protein, rnd transporter, and outer membrane protein, respectively, of kn ... | 2011 | 21930878 |

| Characteristics of microbial aerosols released from chicken and swine feces. | Bioaerosols generated during livestock and poultry production are significant occupational hazards. This study investigates the characteristics of bioaerosols released from animal feces. Fresh feces from pigs and chickens were obtained and tested in a controlled-environment facility. Airborne viable (culturable) bacteria and fungi were sampled hourly for 48 hr. The predominant species were identified via polymerase chain reaction analysis.

| Tsunami lung. | We encountered three cases of lung disorders caused by drowning in the recent large tsunami that struck following the Great East Japan Earthquake. All three were females, and two of them were old elderly. All segments of both lungs were involved in all the three patients, necessitating ICU admission and endotracheal intubation and mechanical ventilation. All three died within 3 weeks. In at least two cases, misswallowing of oil was suspected from the features noted at the time of the detection. ... | 2011 | 22057370 |
| Genotyping of environmental and clinical Stenotrophomonas maltophilia isolates and their pathogenic potential. | Stenotrophomonas maltophilia is a highly versatile species with useful biotechnological potential but also with pathogenic properties. In light of possible differences in virulence characteristics, knowledge about genomic subgroups is therefore desirable. Two different genotyping methods, rep-PCR fingerprinting and partial gyrB gene sequencing were used to elucidate S. maltophilia intraspecies diversity. Rep-PCR fingerprinting revealed the presence of 12 large subgroups, while gyrB gene sequenci ... | 2011 | 22110692 |

| The Ax21 protein is a cell-cell signal that regulates virulence in the nosocomial pathogen Stenotrophomonas maltophilia. | Stenotrophomonas maltophilia encodes proteins related to the Rax proteins of Xanthomonas oryzae, which are required for the synthesis and secretion of the Ax21 protein. Here we show that Ax21 acts as a cell-cell signal to regulate a diverse range of functions, including virulence, in this nosocomial pathogen. | 2011 | 21908663 |
| Reducing Sugar-Producing Bacteria from Guts of Tenebrio Molitor Linnaeus (Yellow mealworm) for Lignocellulosic Waste Minimization. | The guts of Tenebrio Molitor Linnaeus (yellow mealworm) were used as inocula to isolate reducing sugar-producing bacteria during bioconversion of lignocellulose to reducing sugars in this study. Three carbon sources, i.e., carboxymethyl cellulose (CMC), filter paper (FP), and lignocellulosic waste (LIG), were specifically selected; and two types of culturing media (M1 and M2) were used. After 6 months of sequential cultivation, lignocellulose (i.e., polysaccharides) degradation of enrichments M1 ... | 2011 | 21869568 |

| the role of nutrients in the biodegradation of 2,4,6-trinitrotoluene in liquid and soil. | the widely used explosive 2,4,6-trinitrotoluene (tnt) has residues that are potentially explosive, toxic, and mutagenic. tnt and other explosives can be degraded by microorganisms; however, biostimulation is needed for process efficiency. to investigate the effectiveness of using biostimulation to degrade tnt, we added varying concentrations of a nutrient amendment consisting of inorganic salts, plant extracts, and molasses to soil and liquid media. for the inoculum we used a consortium of bacte ... | 2012 | 22245864 |
| stenotrophomonas maltophilia: an emerging global opportunistic pathogen. | summary: stenotrophomonas maltophilia is an emerging multidrug-resistant global opportunistic pathogen. the increasing incidence of nosocomial and community-acquired s. maltophilia infections is of particular concern for immunocompromised individuals, as this bacterial pathogen is associated with a significant fatality/case ratio. s. maltophilia is an environmental bacterium found in aqueous habitats, including plant rhizospheres, animals, foods, and water sources. infections of s. maltophilia c ... | 2012 | 22232370 |
