Background: The choice of the ideal antiseptic is not only based on its efficacy but also on safety and skin-friendliness. There are no standard recommendations regarding ideal skin preparation in neonates.

Methods: This was a prospective cohort study to evaluate the efficacy of 3 antiseptics[10% Povidone Iodine(PI), 70% isopropyl alcohol(AL), 2% chlorhexidine in 70% alcohol(CHG-IPA)] in disinfecting the skin before venipuncture in term neonates as assessed by logarithmic reduction in skin bacterial colony counts post-application.

Purpose: The COVID-19 pandemic caused by the novel Severe Acute Respiratory Syndrome Corona Virus 2 (SARS-CoV-2) has put the world in a medical crisis for the past three years; nearly 6.3 million lives have been diminished due to the virus outbreak. This review aims to update the recent findings on COVID-19 infections from an epigenetic scenario and develop future perspectives of epi-drugs to treat the disease.

Background: Levonadifloxacin (intravenous) and alalevonadifloxacin (oral prodrug) are novel antibiotics based on benzoquinolizine subclass of fluoroquinolone, licensed for clinical use in India in 2019. The active moiety, levonadifloxacin, is a broad-spectrum antibiotic with a high potency against methicillin-resistant Staphylococcus. aureus, multi-drug resistant pneumococci and anaerobes.

Aspergillosis is a systemic fungal infection that commonly affects immunocompromised individuals and, less frequently, immunocompetent individuals. It is the most common opportunistic fungal disease after candidiasis. This is primarily a pulmonary infection and can also involve other body sites like paranasal sinuses and cutaneous tissues.

Article Synopsis
  • * Conducted in a COVID-19 care hospital, the research involved testing 599 samples with both rtRT-PCR and rapid antigen tests (RAT), with rtRT-PCR showing 52% positive results compared to 38% with RAT.
  • * The RAT demonstrated 74.19% sensitivity and perfect specificity, providing fast and cost-effective results, making it a viable option for quickly identifying COVID-19 cases in high-surge areas to enable timely isolation and control measures.

Introduction: Secondary bacterial infections have been reported in majority of patients hospitalized with coronavirus disease 2019 (COVID-19). A study of the antimicrobial susceptibility profiles of these bacterial strains revealed that they were multidrug resistant, demonstrating their resistance to at least three classes of antimicrobial agents including beta-lactams, fluoroquinolones and aminoglycosides. Bacterial co-infection remains as an important cause for high mortality in patients hospitalized with COVID-19.

Article Synopsis
  • Chemically functionalized sensors are commonly used for gas sensing but have stability issues, while uncoated sensors are more durable but lack selectivity.
  • This study explores using multi-parametric discrimination with capacitive micromachined ultrasonic transducers (CMUTs) to differentiate gases like hydrogen, carbon dioxide, and methane using measurements of attenuation coefficient and time of flight in nitrogen mixtures.
  • The paper discusses methods for addressing multiple reflection signals and suggests potential applications in monitoring environments like refueling stations, vehicles, and nuclear waste storage.

Introduction: Streptococcus pneumoniae and Hemophilus influenzae are two major bacterial human pathogens responsible for causing both acute respiratory tract and life threatening invasive infections. Oropharyngeal carriage of these isolates can lead to its transmission frequently in healthcare settings between patients and HealthCare workers (HCW) and also common among population living in crowded communities resulting in serious invasive infections. Furthermore, awareness about preventive measures including appropriate vaccination against these bacterial infections, oropharyngeal carrier status, prevalent serotypes and the antimicrobial susceptibility pattern these bacterial strains among HCW and Non-HCW in the community in India remains inadequate.

Background: Levonadifloxacin is a novel antibiotic belonging to the benzoquinolizine subclass of fluoroquinolones with potent activity against MRSA and quinolone-resistant Staphylococcus aureus. IV levonadifloxacin and its oral prodrug alalevonadifloxacin have recently been approved in India for the treatment of acute bacterial skin and skin structure infections (ABSSSIs) including diabetic foot infections.

Objectives: To investigate the in vitro activity of levonadifloxacin against contemporary clinical isolates collected from multiple tertiary care hospitals across India in the Antimicrobial Susceptibility Profiling of Indian Resistotypes (ASPIRE) surveillance study.

Introduction: Urinary tract infections (UTIs) remain as the most common infection. Catheter-associated (CA) UTI can lead to bacteremia and thereby is the leading cause of morbidity and mortality in hospitalized patients in our country.

Aims And Objectives: This study aims to check the prevalence of CAUTI and study the phenotypic and genotypic characters of the multidrug-resistant organisms in a tertiary care hospital, with special reference to NDM-1 and OXA-23.

Introduction: Urinary tract infections (UTIs) are very common. Indiscriminate use of antibiotics has led to the development of resistance to most of the commonly used antibiotics including quinolones.

Aim: This study aimed to find out the prevalence of ciprofloxacin resistance among the uropathogenic , to determine the virulence factors of these isolates, and to detect the aac-(6)-lb-cr gene among those isolates with minimal inhibitory concentrations (MICs) of ciprofloxacin >256 mcg/ml.

Introduction: Carbapenem resistance among Enterobacteriaceae, especially in Klebsiella pneumoniae and Escherichia coli, is an emerging problem worldwide. A common mechanism of carbapenem resistance is the production of class-A, Klebsiella pneumoniae carbapenemase (KPC).

Aims And Objectives: The present study focused on determining the antibiotic resistance pattern and prevalence of bla KPC gene coding for KPC in carbapenem resistant Enterobacteriaceae.
