In the last few years, numerous cases of multidrug-resistant Achromobacter xylosoxidans infections have been documented in immunocompromised and cystic fibrosis patients. To gain insights into the molecular mechanisms and mobile elements related to multidrug resistance in this bacterium, we studied 24 non-epidemiological A. xylosoxidans clinical isolates(More)
Delivery inside the cells is essential for practical application of antisense technologies. The hybrid locked nucleic acid (LNA)/DNA CAAGTACTGTTCCACCA (LNA residues are underlined) was labeled by conjugation to Alexa Fluor 488 (fLNA/DNA) and tested to determine its ability to penetrate Escherichia coli cells and reach the cytoplasm. Flow cytometry analysis(More)
Achromobacter xylosoxidans is increasingly being documented in cystic fibrosis patients. The bla OXA-114 gene has been recognized as a naturally occurring chromosomal gene, exhibiting different allelic variants. In the population under study, the bla OXA-114-like gene was found in 19/19 non-epidemiological-related clinical isolates of A. xylosoxidans with(More)
Recent studies have demonstrated a high genomic plasticity in Acinetobacter baumannii, which may explain its high capacity to acquire multiple antibiotic resistance determinants and to survive in the hospital environment. Acinetobacter baumannii strain A118 (Ab A118) was isolated in the year 1995 from a blood culture of an intensive care unit patient. As(More)
The emergence of tigecycline resistance has increased in the last years. Although tigecycline-resistant Acinetobacter baumannii isolates were described all over the world, few reports regarding the molecular basis of this resistance are available. It has been recognized that the overexpression of AdeABC efflux pump is related to the tigecycline-resistant(More)
Lactobacillus is normally present in animals and humans colonizing several epithelia, mainly those belonging to the upper gastrointestinal tract. Most of the information about the distribution of Lactobacillus in mice has been obtained by bacterial culture and characterization, and only few reports have described the direct presence of these bacteria in(More)
INTRODUCTION Infections caused by Acinetobacter junii are rarely reported. However, some outbreaks of septicemia in neonates and pediatric oncology patients, as well as meningitis, peritonitis, and ocular infection have been described. Since it is highly infrequent to find the molecular characterization of A. junii strains in literature, in this study we(More)
Last year in 2013, we reported an outbreak due to indigo-pigmented Acinetobacter baumannii strains in a hospital from Buenos Aires, Argentina. Here, we present the draft genome sequence of one of the strains (A. baumannii A33405) involved in the outbreak. This isolate was categorized as extensively drug-resistant (XDR) and harbors different genetic elements(More)
Empedobacter (formerly Wautersiella) falsenii comb. nov. strain Wf282 was isolated from a cervical neck abscess sample from an 18-year-old female patient. The isolate was resistant to many antibiotics, including meropenem and colistin. The total DNA from the multidrug-resistant E. falsenii comb. nov. Wf282 clinical isolate was sequenced.
Helicobacter pylori colonizes the human gastric mucosa, leading to a spectrum of gastric diseases in susceptible populations. Here we announce the draft genome sequences of strains HPARG8G and HPARG63. The data for both genome sequences provide insights regarding the diversity in gene content and rearrangement of the genomic islands commonly harbored by H.(More)
