Antimicrobial and Antibiofilm Activity of a Recombinant Fragment of β-Thymosin of Sea Urchin Paracentrotus lividus
2018
With the aim to obtain new antimicrobials against important pathogens such as Staphylococcus aureus and Pseudomonas aeruginosa, we focused on antimicrobial peptides (AMPs) from Echinoderms. An example of such peptides is Paracentrin 1 (SP1), a chemically synthesised peptide fragment of a sea urchin thymosin. In the present paper, we report on the biological activity of a Paracentrin 1 derivative obtained by recombination. The recombinant paracentrin RP1, in comparison to the synthetic SP1, is 22 amino acids longer and it was considerably more active against the planktonic forms of S. aureus ATCC 25923 and P. aeruginosa ATCC 15442 at concentrations of 50 µ
A Difficult Case of Necrotizing Fasciitis Caused By Acinetobacter baumannii
2010
This study reports the case of a 55-year-old woman with diabetes with a necrotizing fasciitis of the right lower limb and the perineum, first admitted at the emergency department for septic shock with cardiac arrest, and later transferred to the department of surgery. Microbiological and histopathological examination confirmed the diagnosis of necrotizing fasciitis caused by Acinetobacter baumanii. A broad-spectrum antibiotic therapy was administered and later readjusted according to the results of microbiological culture. Intensive hemodynamic support was required. Wounds were dressed daily with a 3 percent boric acid solution and a silver sulfadiazine-impregnated dressing. An extensive s…
Drug resistance patterns of bacteria isolated from patients with nosocomial pneumonia at Tehran hospitals during 2009-2011
2013
Introduction: Nosocomial pneumonia remains an important cause of mortality and morbidity worldwide. Surveillance programs play an important role in the identification of common etiologic agents and local patterns of antimicrobial resistance. Methodology: In this study we determined the frequency and antimicrobial susceptibility of pathogens isolated from patients with nosocomial pneumonia during 2009 to 2011. Results: A total of 642 bacteria were isolated from 516 suspected samples. Acinetobacter baumannii (21.1%, n = 136), was the commonest isolated pathogen followed by Pseudomonas aeruginosa (17.4%, n = 112) , Staphylococcus aureus (15.8%, n = 102) and enterococci (8.4% n = 54). The most …
[Anti-Pseudomonas aeruginosa antibodies and lung disease in cystic fibrosis]
2003
The aim of our study was to diagnose and to control three aspects of the evolution of lung disease in CF: the absence of infection, the intermittent colonization and chronic infection by Pseudomonas aeruginosa. Therefore a study of anti-pseudomonas antibodies (Ab) (anti-protease, anti-elastin and antihexo-toxin A) for diagnosis and follow-up of CF patients was considered. Moreover, we related the presence of Ab to the sputum culture, to FEV1, to patient age and to genotype. Tbe Ab were dosed in 121 patients by quantitative ELISA method. Values < 1: 500 were considered negative, values> 1: 500 and < 1:1250 borderline, and > 1:1250 positive. 16.5% of patients did not have Ab, 17% …
A novel VIM‐type metallo‐beta‐lactamase (VIM‐14) in a Pseudomonas aeruginosa clinical isolate from a neonatal intensive care unit
2011
AbstractA Pseudomonas aeruginosa highly resistant to carbapenems was isolated in a neonatal intensive care unit in Palermo, Italy. The strain was found to carry a novel VIM‐type enzyme, classified as VIM‐14. The novel enzyme differs from VIM‐4 in a G31S mutation. VIM‐14 was harboured in a class 1 integron with a new organization. The integron carried the genes aac7, blaVIM‐14, blaOXA‐20 and aac4 in that order.
Intervención nutricional en niños y adolescentes con fibrosis quística. Relación con la función pulmonar
2005
Cecilia.Martinez@uv.es; Francisco.Nunez@uv.es; Objetivo: Evaluar los efectos de la intervención nutricional precoz y continuada en pacientes pediátricos con fibrosis quística (FQ) y su posible implicación en la función pulmonar. Pacientes y métodos: Se incluyen el seguimiento de 19 pacientes con FQ (11 niñas, 8 niños) de 17 meses a 18 años de edad y promedio de 10 años de enfermedad. El genotipo de 16 pacientes es delta F 508 (10 homo, 6 heterocigotos). Cada 2-3 meses se les ha realizado: valoración clínica, dietética y antropométrica clasificando el estado de nutrición (EN) según Z pesto/talla, % peso para la talla, índice de masa corporal y Z talla/edad. Coincidentemente se obtuvo cultivo…

Carga y factores de riesgo para la neumonía adquirida en la comunidad de Pseudomonas aeruginosa : un estudio multinacional de prevalencia puntual de …
2018
Pseudomonas aeruginosa is a challenging bacterium to treat due to its intrinsic resistance to the antibiotics used most frequently in patients with community-acquired pneumonia (CAP). Data about the global burden and risk factors associated with P. aeruginosa-CAP are limited. We assessed the multinational burden and specific risk factors associated with P. aeruginosa-CAP. We enrolled 3193 patients in 54 countries with confirmed diagnosis of CAP who underwent microbiological testing at admission. Prevalence was calculated according to the identification of P. aeruginosa. Logistic regression analysis was used to identify risk factors for antibiotic-susceptible and antibiotic-resistant P. aeru…
