Antibacterial Activities of Methanolic Seeds Extract of Black pepper (Piper nigrum L.) against Gram Positive Staphylococcus aureus & Gram-Negative Escherichia coli.

Evaluation of the in vitro antibacterial activity of Methanolic extracts isolated from Black pepper seeds (Piper nigrum L.) against two infection causing pathogens, Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli. Between July 2022 and June 2023, this experimental study was conducted at the Mymensingh Medical College's Department of Pharmacology and Therapeutics in conjunction with the Department of Microbiology. Using the disc diffusion and broth dilution methods, the antibacterial activity of methanolic extract of black pepper seeds (MBPE) was evaluated at various doses. The solvents Methanol and 10.0% Di Methyl Sulfoxide (DMSO) were used to make the extract. Using the broth dilution procedure, the conventional antibiotic Ciprofloxacin was utilized and the outcome was contrasted with that of Methanol extracts. Methanolic extract of black pepper seeds (MBPE) at seven distinct concentrations (100, 80, 60, 40, 20, 10 and 5 mg/ml) were utilized, then later in chosen concentrations as needed to confirm the extracts' more precise margin of antimicrobial sensitivity. At 80 mg/ml and above doses of the MBPE, it had an inhibitory impact against the aforementioned microorganisms. For Staphylococcus aureus and Escherichia coli the MIC were 60 and 75 mg/ml in MBPE respectively. As of the MIC of Ciprofloxacin was 1µg/ml against Staphylococcus aureus and Escherichia coli. In comparison to MICs of MBPE for the test organisms, the MIC of Ciprofloxacin was the lowest. This study clearly shows that Staphylococcus aureus and Escherichia coli are sensitive to the methanolic extract of black pepper seeds' antibacterial properties.

Current Trends of Using Antimicrobials in Acute Watery Diarrhoea in Children Below 5 Years of Age at Paediatrics Outpatient Department of a Tertiary Care Hospital in Bangladesh.

Childhood diarrhoea is a major public health problem in developing countries like Bangladesh which is commonly caused by intestinal infection, mainly viral. Diarrhoea is causing second leading mortality in children below 5 years, where about 2 billion cases occur globally in each year. This study was proposed to evaluate the antimicrobials utilization pattern prescribed for AWD in children below 5 years of age, in a tertiary care hospital in Bangladesh. This record based, cross-sectional, descriptive type of observational study carried out at pharmacology department of Mymensingh Medical College. A total of 205 diarrhoeal patient's up to 5 years of age, attending the paediatric OPD from January 2021 to December 2021, were enrolled in the study. Out of 205 patients 182(88.8%) were prescribed antimicrobials. Azithromycin was the most frequently prescribed antimicrobial (60.0%) and among the antiprotozoals metronidazole was the prescribed most (24.9%). ORS and Zinc were prescribed in all patients (100%). Empirical excessive use of antibiotics was observed in this study. Emphasis on educational and training programs may help in a better and judicious use of drugs in children.
