REDUCED SUSCEPTIBILITY OF MRSA TO VANCOMYCIN

Objective: This study was conducted to observe the antibiogram, vancomycin MIC (Minimum Inhibitory Concentration), and inducible clindamycin resistance in clinical isolates of MRSA (Methicillin-Resistance Staphylococcus aureus).Methods: Drug resistance pattern was studied by Kirby-Bauer disc diffusion methods. MIC of vancomycin was determined by agar dilution method.Results: MRSA was found to be highly resistant to gentamicin (76%), erythromycin (67.03%) and ciprofloxacin (65.09%) while glycopeptides showed uniform susceptibility.Conclusion: Though there was no drug resistance observed against vancomycin and linezolid, it's wise to use these antibiotics safely as emerging resistance has been reported for these drugs from all over the world

“NEWS ON AIR!” - AIR SURVEILLANCE REPORT FROM INTENSIVE CARE UNITS OF A TERTIARY CARE HOSPITAL

ABSTRACTBackground: The role of airborne microorganisms in the nosocomial infections is debatable since past. Very limited and inconclusive data availableabout the contribution of the air microflora, especially the multidrug resistant (MDR) one, to the hospital-acquired infections in the Intensive CareUnits (ICUs).Objective: To analyze the microbial population and their antimicrobial susceptibility pattern of the indoor air in relation to the nosocomial infectionsin the different ICUs at different periods in the tertiary care hospital.Methods: Microbial monitoring of the air was performed in 5 different ICUs for 1 year by passive sampling method.Results: A total of 221 air samples were collected for 1 year from five different ICUs. 92.53% were Gram-positive bacteria and 8.11% were Gramnegativebacteria. Staphylococcus spp. (34.21%) and Acinetobacter spp. (63.04%) were the most common isolated bacteria among Gram-positiveand Gram-negative organisms, respectively, and among the fungal isolates, all of them were Aspergillus spp. (5.84%) from the air sample. Ventilatorassociatedpneumonia was the most common nosocomial infection and Acinetobacter spp. was the frequently isolated MDR organism.Conclusion: Air could be the major source of nosocomial infections by MDR Gram-negative organisms in the ICUs which require special attention andsurveillance.Keywords: Air sampling, Intensive Care Units, Multidrug-resistant organisms, Nosocomial infection

Creación y Simulación de Metodologías de Análisis, Clasificación e Integración de Nuevos Requerimientos a Software Propietario

La priorización de nuevos requerimientos a implementar en un software propietario es un punto fundamental para su mantenimiento, la conservación de la calidad, observación de las reglas de negocio y los estándares de la empresa. Aunque existen herramientas de priorización basadas en técnicas probadas y reconocidas, las mismas requieren una calificación previa de cada requerimiento. Si la empresa cuenta con solicitudes provenientes de varios clientes de un mismo producto, aumentan los factores que afectan a la empresa, las herramientas disponibles no contemplan estos aspectos y hacen mucho más compleja la tarea de calificación. Este trabajo de investigación abarca la realización de un relevamiento de los métodos de priorización y selección de nuevos requerimientos utilizados por empresas de la zona de Rosario, y la definición de una metodología para la selección un nuevo requerimiento, que implica el análisis y evaluación de todas las implicaciones sobre el producto de software y la empresa, respetando sus reglas de negocio. La metodología creada conduce a la definición de los procesos para la construcción de una herramienta de calificación y priorización de nuevos requerimientos en software propietario que tiene solicitudes de varios clientes al mismo tiempo, con instrumentos de calificación que consideran todos los aspectos relacionados, proveerá técnicas de priorización actuales y emitirá informes personalizados según diferentes perspectivas de la empresa.Eje: Ingeniería de SoftwareRed de Universidades con Carreras en Informática (RedUNCI

Role of laboratory in rapid diagnosis of atypical mumps

Fairly large number of mumps virus infections present atypically without parotitis leading to delay in diagnosis and increased morbidity. Awareness of such presentations and inclusion of serological test for detecting IgM-specific antibodies could help in solving diagnostic dilemma, especially in unvaccinated individuals from developing countries

Bacterial isolates of early-onset neonatal sepsis and their antibiotic susceptibility pattern between 1998 and 2004: an audit from a center in India

Abstract Background Epidemiology and surveillance of neonatal sepsis helps in implementation of rational empirical antibiotic strategy. Objective To study the frequency of bacterial isolates of early onset neonatal sepsis (EONS) and their sensitivity pattern. Methods In this retrospective study, a case of EONS was defined as an infant who had clinical signs or born to mothers with potential risk factors for infection, in whom blood culture obtained within 72 hours of life, grew a bacterial pathogen. Blood culture sample included a single sample from peripheral vein or artery. Relevant data was obtained from the unit register or neonatal case records. Results Of 2182 neonates screened, there were 389 (17.8%) positive blood cultures. After excluding coagulase-negative Staphylococci (160), we identified 229 EONS cases. Preterm neonates were 40.6% and small for gestational age, 18.3%. Mean birth weight and male to female ratio were 2344.5 (696.9) g and 1.16:1 respectively. Gram negative species represented 90.8% of culture isolates. Pseudomonas (33.2%) and Klebsiella (31.4%) were common among them. Other pathogens included Acinetobacter (14.4%), Staphylococcus aureus (9.2%), E.coli (4.4%), Enterobacter (2.2%), Citrobacter (3.1%) and Enterococci (2.2%). In Gram negative group, best susceptibility was to Amikacin (74.5%), followed by other aminoglycosides, ciprofloxacin and cefotaxime. The susceptibility was remarkably low to ampicillin (8.4%). Gram positive group had susceptibility of 42.9% to erythromycin, 47.6% to ciprofloxacin and above 50% to aminoglycosides. Of all isolates, 83.8% were susceptible to either cefotaxime or amikacin Conclusion Gram-negative species especially Pseudomonas and Klebsiella were the predominant causative organisms. Initial empirical choice of cefotaxime in combination with amikacin appeared to be rational choice for a given cohort.</p
