Research Problem: Given that Pseudomonas aeruginosa is an oportunistic phatogen, the composition, structure and/or transcription eficiency of its accesory genome – those variant genetic elements that can give an advange to certain strains in a given niche – can help to dilucidate the relations between purely environmetal strains and clinical strains
Sensory impaired individuals are at a disadvantage in accessing and processing electronic information. The first author (i.e. Thomas Hahn) is legally blind due to Albinism. In this experience report we describe challenges faced by the visually impaired and explain how remote access programs in combination with voice communication programs can be used to---at least partially---compensate for those disadvantages because they don't transmit magnification. This property is especially important to effectively train visually impaired individuals on new applications and interfaces remotely because it allows them to view exactly the same information simultaneously with their sighted trainers. Since the technical prerequisites for this information exchange, skill transfer, and knowledge acquisition approach have already been freely available for at least 7 years, but are still not widely used, this approach needs to be impressively demonstrated at conferences like this one to increase the odds that its participants will share this approach with those who could potentially benefit from it. This approach could make computer labs with expensive software not only accessible to the disabled, but instead, to everyone around the clock while saving money, which is still being spent to pay lab supervisors to keep the labs open for a few hours without losing---but instead---gaining functionality. Offering virtual remote office hours would benefit disabled and non-handicapped students and faculty alike. Providing remote access to lectures can make them available to a wider audience and thus could decrease costs for tuition. Obvious benefits of this approach for the mobility impaired and soon to be expected benefits for the hearing impaired are mentioned. Allowing faculty to remotely participate in oral exams increases choices for possible specializations. Making information more accessible to the disabled has obvious synergistic benefits for non-handicapped people alike as reflected by the importance of the concept of workforce diversification for overcoming unexpected future challenges and potential stumbling blocks. This approach makes it possible to magnify lecture presentations directly onto the screen of visually impaired students and could improve real-time interactions in the classroom. Remote access for everyone could reduce the perception of disabilities. Handicapped people could be considered early adopters because they are more in need of improvements since the present circumstances and limitations are much less acceptable to them. This article concludes by describing current bottlenecks to accessibility and information transfer, and ends with an overall optimistic outlook to the future.

Biofilms of Pseudomonas aeruginosa strains have different expression profiles when growing on crude oil droplets and on cooking oil droplets. Differences were observed in the expression of genes associated to alkane degradation, system MexCD-OprJ, MExX-oprm and ExoS, ExoT. A technique for isolation of biofilms associated to crude oil was standardized. The technique allowed us to isolate RNA directly from the biofilms. Additionally, biofilms from each strain were characterized using bright field microscopy and a 3D model of the biofilms were attempted using confocal fluorescence microscopy. Also, changes in colony morphology, swimming, swarming and twitching after growing in crude oil were characterized for each strain.

We established basis for a datetelling method of leaves (Tillandsia spp.) consumed by Tremarctos ornatus by determining or detecting the presence of microorganisms. We used samples from the field that corresponded to different states of decomposition. The samples (2 cm from the leaf base consumed by the animal) were processed in the laboratory, characterized and determined. Cocobacilli (Pseudomonas sp.) and negative bacilli Gram were the most common bacteria morphotypes, the first were founded on samples from all ages and the second on samples no older than six months. Positive cocobacili Gram (Bacillus sp.); were just present in samples between one and three months old. Positive Gram bacilli occurred only in samples no older than a month, cocos and diplococos in samples between five and six months. Four fungus morphotypes were found, two of them being Mucor sp., and Trichoderma sp., in addition to Epicoccum sp., Alternaria sp., Rhizoctonia sp. Trichoderma was associated with at least one more kind of fungus, for samples to older than one month, but no older than five months.
