Monitoring and Outcomes of Central Line-Associated Bloodstream Infections in a Tertiary Care Intensive Care Unit.

Background Central line-associated bloodstream infections (CLABSIs) are significant healthcare-associated infections that increase morbidity, mortality, and healthcare costs. This study aims to analyze the frequency, microbiology, risk factors, and outcomes of CLABSI in an adult intensive care unit. Methods We conducted a hospital-based, prospective surveillance study in the critical care unit of a tertiary care hospital.

Antimicrobial resistance pattern of Helicobacter pylori in patients evaluated for dyspeptic symptoms in North-Eastern India with focus on detection of clarithromycin resistance conferring point mutations A2143G and A2142G within bacterial 23S rRNA gene.

Purpose: In India there is evidence of antimicrobial resistance in Helicobacter pylori, a definitive pathobiont whose only known niche is human gastric mucosa. This in turn can lead to failure of treatment, persistence or chronicity of infection. This hospital based, prospective, observational study investigates the presence of antimicrobial resistance in the organism with focus on detection of A2143G and A2142G major point mutations in domain V of H.

Distribution of carbapenem resistant Acinetobacter baumannii with bla and induction of ADC-30 in response to beta-lactam antibiotics.

A wide range of intrinsic Acinetobacter-derived cephalosporinases (ADC) along with other carbapenemases has now been detected in Acinetobacter baumannii leaving clinicians with few treatment options. The present study reports the spread of ADC-30 co-producing KPC-2 along with other β-lactamases among carbapenem resistant A. baumannii strains obtained from ICU patients in two Indian hospitals.

Real-time multiplex polymerase chain reaction with high-resolution melting-curve analysis for the diagnosis of enteric infections associated with diarrheagenic .

Introduction: Although diarrheagenic Escherichia coli (DEC) strains are important bacterial causative agents of diarrhoea, they are not routinely sought as stool pathogens in clinical laboratories as conventional microbiological testing are unable to distinguish between normal flora and pathogenic strains of E. coli. This study was undertaken to determine the prevalence of DEC pathotypes amongst children with and without diarrhoea and to detect specific virulent genes present in different DEC pathotypes, using real-time multiplex polymerase chain reaction (PCR) with high-resolution melting (HRM) technology.

High-level aminoglycoside resistance in recovered from Intensive Care Unit patients in Northeastern India.

Background: Acinetobacter baumannii has emerged as an important nosocomial pathogen, its ability to acquire resistance to carbapenems and aminoglycosides, has complicated their treatment regimen. The present study investigates the prevalence and diversity of aminoglycoside-modifying enzymes and 16S methyltransferases in A. baumannii isolates recovered from patients admitted in Intensive Care Unit (ICU) of a tertiary referral hospital in Northeastern India.

Clinico-aetiologic profile of Onychomycoses in a tertiary care centre in northeast India.

Onychomycosis refers to fungal nail infection. Despite a clearly diseased appearance, it is often deemed a merely cosmetic problem of relatively minor importance. However, it may result in much psychological or occupational turmoil, diminished self-esteem and resulting reluctance for public interaction.

Comparative evaluation of the role of single and multiple blood specimens in the outcome of blood cultures using BacT/ALERT 3D (automated) blood culture system in a tertiary care hospital.

Introduction: Bloodstream infection (BSI) is a leading cause of mortality in critically ill patients. The mortality directly attributable to BSI has been estimated to be around 16% and 40% in general hospital population and Intensive Care Unit (ICU) population, respectively. The detection rate of these infections increases with the number of blood samples obtained for culture.

Inducible and constitutive clindamycin resistance in Staphylococcus aureus in a northeastern Indian tertiary care hospital.

Introduction: Staphylococcus aureus is one of the most common pyogenic bacteria. They are notorious for developing prompt resistance to newer antimicrobials. With increasing incidence of methicillin-resistant S.

Association of biofilm production with multidrug resistance among clinical isolates of Acinetobacter baumannii and Pseudomonas aeruginosa from intensive care unit.

Background And Aims: Given choice, bacteria prefer a community-based, surface-bound colony to an individual existence. The inclination for bacteria to become surface bound is so ubiquitous in diverse ecosystems that it suggests a strong survival strategy and selective advantage for surface dwellers over their free-ranging counterparts. Virtually any surface, biotic or abiotic (animal, mineral, or vegetable) is suitable for bacterial colonization and biofilm formation.

Sub-cutaneous abscess caused by Nocardia asteroides in renal transplant recipient.

Nocardia is a significant opportunistic pathogen in patients with compromised immunity. Nocardia asteroides was isolated from subcutaneous abscesses on the left thigh and shoulder of a renal transplant recipient. Direct examination of the aspirated pus showed branching filaments that were gram-positive and acid fast.

Antifungal susceptibility of Cryptococcus neoformans to amphotericin B and fluconazole.

Cryptococcus neoformans has emerged as an important opportunistic fungal pathogen in immunocompromised individuals. The therapeutic options of C. neoformans an opportunistic fungal pathogen include flucytosine, amphotericin B, and azole agents.

Atypical mycobacterial infection among HIV seronegative patients in Pondicherry.

Background: The role of non-tuberculous mycobacteria (NTM) as aetiological agents in the causation of lung infections has seldom been systematically studied from India.

Methods: Prospective study of Species identification from mycobacterial isolates.

Results: A total of 22 isolates of mycobacteria were isolated from 635 samples of suspected tuberculosis in a two months period, of which 17 were Mycobacterium tuberculosis, three Mycobacterium kansasii and one each of Mycobacterium fortuitum and Mycobacterium gordonae.
