Bacteria from the Burkholderia cepacia complex (Bcc) are capable of causing severe infections in patients with cystic fibrosis (CF). These opportunistic pathogens also widely distributed natural and man-made environments. After a 12-year epidemiological surveillance involving Bcc bacteria respiratory secretions Argentinean CF hospital settings, we found six isolates concatenated species-specific allele sequence that differed by more than 3 % those validly published names. According to...
ABSTRACT A total of 120 Burkholderia cepacia complex isolates collected during 2004–2010 from 66 patients in two cystic fibrosis reference centers Argentina were analyzed. contaminan s was the species most frequently recovered (57.6%), followed by cenocepacia (15%), a distribution not reported so far. The recA -PCR-based techniques applied to B. contaminans revealed that 85% population carried -ST-71 allele. Our results showed utility BOX-PCR genotyping analyzing diversity. This approach...
Different phenotype-based techniques and molecular tools were used to describe the distribution of different Achromobacter species in patients with cystic fibrosis (CF) Argentina, evaluate their antibiotic resistance profile. Phenotypic identification was performed by conventional biochemical tests, commercial galleries MALDI-TOF MS. Genetic approaches included detection A. xylosoxidans specific marker blaoxa-114, amplification sequencing 16S rRNA gene, nrdA blaOXA complete sequence, MLST...
Pandoraea species are considered emerging pathogens in the context of cystic fibrosis (CF) and difficult to identify by conventional biochemical methods. These multidrug resistant bacteria remain poorly understood particularly terms natural resistance, mechanisms acquired resistance impact on prognosis disease lung function. Among them, sputorum has been previously described few cases CF patients from Spain, Australia, France United States, underlining need more clinical data for a better...
It is recognized that mobile phones may play a role in microorganism transmission and hand hygiene, considered the most important action for preventing infections spread of pathogens. The objective this study was to determine presence circulation bacteria on hands capable causing people also if disinfection with gel-alcohol useful reduce bacterial colonization.The evaluation included 596 participants 256 phones. Isolated colonies were identified by biochemical test confirmed gene 16S rRNA...
We investigated the genetic differentiation of five X-chromosome STR markers among native South American Amerindian populations inhabiting three different areas Gran Chaco: Mocoví, Chorote, Wichí, Lengua, and Ayoreo. The observed structure showed correspondence with geographic distribution more clearly than previous information obtained from autosomal STRs for same samples. On other hand, data did not agree linguistic affinities. These proved to be informative study Chaco region.
Abstract Type‐IV pili are cell surface organelles found in a wide variety of Gram‐negative bacteria. They have traditionally been detected by electron microscopy and ELISA techniques. However, these methodologies not appropriate for the rapid discrimination quantification piliated nonpiliated cells industrial or field conditions. Here, analysis FT‐IR spectra piliated, sheared Moraxella bovis cells, together with purified suspensions spectra, allowed identification 3 IR regions associated to...
The Wiehí people from Chaco Province inhabit the region called Impenetrable Chaqueño, where climatic conditions are extreme. Besides scarce communication with main urban centers, cultural patterns of Wichí cause these communities to live in certain degree isolation. effect this situation is an increased genetic differentiation other populations, as it was observed through autosomal and Y chromosome markers. However, variation X has not yet been fully analyzed. allele distribution different...
Cystic fibrosis patients with Burkholderia cepacia complex pulmonary infections have high morbidity and mortality. Worldwide, this disease is undergoing substantial epidemiological changes. Advances in the diagnosis treatment conditioned an increase child survival as well proportion of affected adults. In order to know our reality, we refer study 64 CF during 11 years surveillance, focusing on caused by species. Conventional automated phenotypic tests, restriction fragment length...
The purpose of this study was to investigate essential oils (EOs) from leaves Elionurus muticus growing in Northeastern Argentina regarding their physicochemical profiles as well biological potential. Roots a selected E. population were investigated too. For purpose, EOs fresh materials obtained by steam distillation and the chemical composition characterized gas chromatography GC/MS-FID. Antibacterial, antioxidant eco-toxicity activities tested vitro assays. showed three chemotypes: citral...

Aedes aegypti plays a predominant role in the transmission of variety diseases, such as yellow fever, dengue malaria, Zika and Chikungunya disease. The reduction chemicals available for vector control due to increase mosquito resistance insecticides their negative impact on human health environment have driven focus problem towards identification evaluation sustainable alternatives synthetic insecticides. essential oils from leaves Ocimum campechianum, ovatum, selloi were analyzed by GC/MS...
El manejo clínico y epidemiológico de los pacientes con fibrosis quística (FQ) exacerbaciones pulmonares agudas o infecciones crónicas demanda una actualización permanente procedimientos médicos microbiológicos, estos se asocian la constante evolución agentes patógenos durante colonización su hospedador. Para poder monitorear dinámica procesos es fundamental disponer sistemas expertos que permitan almacenar, extraer utilizar información generada a partir estudios realizados sobre el paciente...
La pérdida de variabilidad genética en el cromosoma Y es frecuente grupos étnicos reducidos numéricamente, debido a que este suele estar sometido barridos selectivos. A pesar ser pequeña, la población Mocoví conserva una cantidad significativa variación relación con otras comunidades nativas, pero su diversidad nivel del no se conoce profundidad. El objetivo trabajo fue analizar muestra varones provincia Santa Fe (Argentina). Se tipificaron 11 microsatélites (STRs) y dos marcadores...
We report here the draft genome sequence of Burkholderia puraquae type strain CAMPA 1040, a member cepacia complex. This strain, isolated from hemodialysis water reservoir, harbors several stress tolerance genes, such as systems for low oxygen survival, copper tolerance, and osmotic resistance.
