Bacterial biofilms due to antibacterial resistance are causing serious health issues with respect to infection control, its prognosis and treatment of disease. The current scenario demands need of new and alternative antibacterial compounds for treatment of such infections. The current study highlights the use of polluted river, Waldhuni, as a source of potent microorganisms with antibiofilm properties. 186 microorganisms were isolated from Waldhuni River, and tested for quorum sensing inhibitory activity (QSI) against C. violaceum MTCC 2656. Seven isolates exhibited QSI activity, out of which 1 isolate PB2 was selected for further study based on its high QSI potential. PB2 displayed broad spectrum antibiofilm activity against eight strains of biofilm forming pathogens. The effective minimum biofilm eradication concentration (MBEC) of crude extract of PB2 secondary metabolite (SME) was found to be 500ppm. The extract reduced exo-polysaccharide (EPS) by 94.16%, viability by 90% and biofilm density by 96% in 6h treatment. It also rendered to inhibit extracellular DNA of Streptococcus mutans MTCC497, Enterococcus faecalis MTCC 439 and Pseudomonas aeruginosa MTCC...

Rapid, sensitive, specific and validated colorimetric methods have been developed for the quantitative estimation of ambroxol HCl in bulk and dosage form. The current method was developed based on oxidation of ambroxol with Gibb’s reagent (method I) and p-diethyl amino benzaldehyde in toluene (method II). The formed intense colour complex was measured at 537.2 nm and 438.4 nm respectively. Under optimized experimental conditions, Beer’s law is obeyed in concentration range 5 – 30 µg/ml for both the methods with regression co-efficient 0.9994 and 0.9992. Recovery studies were conducted by standard addition method to confirm the accuracy of the method. The LOD and LOQ for the estimation of ambroxol were found as 0.0773, 0.2343 for method I and 0.0667, 0.2021 for method II respectively. The proposed method was validated as per ICH...

Objective: To assess the pattern of adverse drug reactions (ADRs) in a tertiary care hospital. Materials and methods: This study was conducted in VSS Medical College, Burla, Odisha from October 2012 to September 2014. ADRs collected from various clinical departments were compiled and analyzed for distribution of age, gender, department, drug class and organ system. Assessment of causality, severity, and preventability was done using specific scales. Results: The occurrence of ADRs was more in males compared to females in the age group 19-60 years of age. Most of the ADRs were collected from medicine department followed by dermatology and psychiatry. The skin was the most common organ system affected followed by gastrointestinal and central nervous system. Antiretroviral drugs were the most common drugs causing ADRs followed by antimicrobials and antipsychotics. Skin rashes were the most common reaction followed by vomiting and extrapyramidal symptoms (EPS). Causality assessments of ADRs were probable for 35.71 % and possible for 64.29 %. Most of the ADRs were of moderate severity (47.48 %) followed...

Bioremediation is a waste management method where we can employ different types of microorganism’s to nullify the effect of pollutants from a contaminated site. In the current study the authors have carried out a three months study to find out how different bacterial strains of Bacillus licheniformis, B. substilis and pseudomonas species can be used to assess the water quality in terms of parameters like pH, dissolved oxygen, free ammonia, total ammonia and nitrite and turbidity from the discharge of common ponds. The study was carried to evaluate the physico-chemical parameters of the catla and selavathi culture ponds by applying probiotics. During the process of investigation one pond was treated with probiotics having Bacillus licheniformis, B. subtilis and Pseudomonas species and to study the efficacy of results the pond to which probiotics were not added was kept as control. The current study is aimed not only to focus on the changes in water quality but also biochemical characterization of bacterial species and to understand what concentration of the bacterial...

The present study was aimed to evaluate the effectiveness of some sesame oils obtained from different cities of Yemen. Sensitivity testing against some pathogenic bacteria and fungi were studied with four types of sesame oils in the laboratory pouring aqueous extract of the sesame seeds into the wells of the culture media. Escherichia coli, Staphylococcus aureus, Salmonella typhi, Candida albicans, Aspergillus niger and Aspregillus flavus were the microorganisms used and they were identified, confirmed and obtained from the Microbiology laboratory of the Sana’a University, Yemen. The results indicated that Semsum sanani and Semsum dwaini showed more antifungal activity against Aspergillus niger and Aspergillus flavus, while Semsum shahri, Semsum hadedi, did not show any activity against pathogenic bacteria and fungi. This study suggests that the compounds found in the semsum oil can form the basis for the development of novel broad spectrum antimicrobial formulations. These results support the notion that semsum oil may have many pharmaceutical...
