Biofilm formation in Mycobacterium species significantly contributes to their pathogenicity and resistance to conventional antimicrobial therapies, posing a major challenge in clinical management. Plant-derived phytoconstituents have emerged as promising alternatives due to their diverse biological activities, including anti-biofilm properties. Clerodendrum serratum, a medicinal plant known for antimicrobial potential, offers a rich source of such bioactive compounds.

A comprehensive, near-real-time assessment of substance use can offer critical insights to -improve the effectiveness of current harm reduction strategies aimed at preventing overdose fatalities. This study employed wastewater-based epidemiology to monitor psychostimulants, opioids, medications for opioid use disorder, antipsychotics, antidepressants, and cannabis over 12 months in a community operating a syringe services program -. On average, an estimated 44,000 monthly doses of methamphetamine (2660 ± 547 mg/d/1000 people), 41,600 doses of oxycodone (159 ± 109 mg/d/1000 people), 9600 doses of cocaine (688 ± 240 mg/d/1000 people), and 19,000 doses of venlafaxine (242 ± 47.

Background: The upsurge of antibiotic resistance is a significant challenge to public health, and the dry pipeline of new antibiotics has prompted the discovery of alternative treatment approaches. () isolates are often multidrug-resistant, posing challenges to antibiotic therapy. Bacteriophage therapy is being explored as an alternative method to treat the growing population of antibiotic-resistant infections.

The world is running short of effective antibiotics due to rapid development of antibiotic resistance against currently available antibiotics. The frequency of new antibiotic discovery from conventional axenic cultures has decreased significantly. In current study, azithromycin and ciprofloxacin supplemented plates were used as selection filter for isolation of antibiotic-producing bacteria from Gomti river sediments.

Background: Endophytic fungi represent a compelling assemblage of microorganisms that inhabit plant tissues without inflicting any discernible detriment to the host organism. They foster a symbiotic association with their host plants, frequently conferring advantages such as augmented growth, enhanced resilience to stressors, and safeguarding against pathogens.

Article Synopsis
  • A study conducted at Banaras Hindu University aimed to identify the causes of Acute Encephalitis Syndrome (AES) in adults, an area previously under-researched compared to studies focused on children and the Japanese encephalitis virus (JEV).
  • The research involved collecting blood and cerebrospinal fluid (CSF) samples from patients older than 18 with fever and altered sensorium, employing various diagnostic tests for different infections.
  • The findings revealed that tuberculous meningitis (TBM) was the most common cause of AES (16.7%), followed by leptospirosis (15.1%) and scrub typhus (11.9%), emphasizing the need for rapid detection and treatment of these conditions.

Article Synopsis
  • The rise of multidrug-resistant mycobacteria poses a serious challenge in treating tuberculosis, leading to treatment failures and reliance on more toxic, expensive medications.
  • This study investigates the use of green-synthesized silver nanoparticles (AgNPs) and their polyethylene glycol encapsulated version (PEG-AgNPs) as potential novel antimicrobials, demonstrating that PEG-AgNPs have better stability and enhanced anti-mycobacterial activity.
  • Characterization techniques revealed the uniform size and stability of PEG-AgNPs, and their effectiveness was shown through increased cell wall permeability and significant biofilm inhibition, along with a lack of toxicity towards human red blood cells.

Background: Chronic wounds are prevalent globally at endemic proportions. The common features associated with chronic wounds are prolonged inflammatory phase, infection with multidrug-resistant (MDR) bacteria, and subsequent biofilm formation. The present randomized-controlled trial (RCT) study was undertaken on chronic wounds of ≥6 weeks longer duration using customized phages to evaluate the efficacy and safety of bacteriophage therapy.

The recent approval of experimental phage therapies by the FDA and other regulatory bodies with expanded access in cases in the United States and other nations caught the attention of the media and the general public, generating enthusiasm for phage therapy. It started to alter the situation so that more medical professionals are willing to use phage therapies with conventional antibiotics. However, more study is required to fully comprehend phage therapy's potential advantages and restrictions, which is still a relatively new field in medicine.

Klebsiella pneumoniae is regarded as one of the most profound bacteria isolated from the debilitating injuries caused by burn wounds. In addition, the multidrug resistance (MDR) and biofilm formation make treating burn patients with clinically available antibiotics difficult. Bacteriophage therapy has been proven an effective alternative against biofilm-mediated wound infections caused by MDR bacterial strains.

Multidrug-resistant (MDR) () is one of the major pathogens present in burn wound infections. Biofilm formation makes it further challenging to treat with clinically available antibiotics. In the current work, we isolated the -specific bacteriophages (BPABΦ1), loaded into the chitosan microparticles followed by dispersion in gel, and evaluated therapeutic efficacy against MDR clinical strains.

To control the spread of the disease, the Zika virus (ZIKV), a flavivirus infection spread by mosquitoes and common in across the world, needs to be accurately and promptly diagnosed. This endeavour gets challenging when early-stage illnesses have low viral loads. As a result, we have created a biosensor based on surface-enhanced Raman scattering (SERS) for the quick, accurate, and timely diagnosis of the Zika virus.

Japanese encephalitis (JE) is a mosquito-borne flavivirus infection named Japanese Encephalitis Virus (JEV), prevalent in Asia-pacific countries, requires an accurate and rapid diagnosis to contain the outbreak of the disease. In cases of low viral load in early-stage infections, this task becomes difficult. Therefore, we have developed a surface-enhanced Raman spectroscopy (SERS) based biosensor for rapid, sensitive, and early-stage detection of JE antigen.
