Objective: Antibiotics resistance patterns for many bacteria have changed significantly; causing poor clinical outcomes. The objective of the study was to measure the susceptibility of different antibiotics against specific clinical isolates for surveillance purpose. Method: Kirby-Bauer disc diffusion method was used to evaluate the susceptibility pattern of four antibiotics (commercially available disc) i.e., Amoxicillin, Cefixime, Ciprofloxacin and Levofloxacin against different clinical isolates collected from various hospitals. The clinical isolates selected for the proposed study were of Staphylococcus aureus, Streptococcus Pneumoniae, Klebsiella Pneumoniae, Pseudomonas aeruginosa, Salmonella typhi and Escherichia coli. This collection of antibiotics and isolates were due to common pathogens and highly prescribed Oral antibiotics. Result: Results show that amoxicillin and cefixime are highly resistant; cefixime is sensitive against Salmonella typhi and Streptococcus Pneumoniae but 50 % resistant to the microbes. In quinolones, ciprofloxacin and levofloxacin have good sensitivity; Levofloxacin is a better choice against aforementioned pathogens. Conclusion: It was concluded that bacterial resistance rates vary among species and also from hospital to hospital. Irrational uses of antibiotics cause...

Hemidesmus indicus Linn. R. Br. is a twining shrub traditionally used for the treatment of various diseases and ailments in the rural area of Bangladesh. Different extracts (methanol, hexane, ethyl acetate, n-butanol and water) from the roots of this shrub tested for their antimicrobial, cytotoxicity and free radical scavenging activities. All extracts showed moderate free radical scavenging activity and SC50 values ranging from 24.98µg/mL to 93.14µg/mL, and sufficient potency for their brine shrimp lethality activity and IC50 values from 1.32µg/mL to 8.67µg/mL. The n-hexane extract showed significant antimicrobial activity against all tested organisms, with a zone inhibition ranging from 10 mm to 27 mm at the concentration of 400µg/disc. Bioassay guided fraction of the extracts has led to isolation of two triterpeniods, 3β-O-acetyl β-amyrin, lupeol 3- β -acetate and a phenolic compound, 2-hydroxy-4-methoxy benzaldehyde. The structures of the compounds were elucidated on the basis of spectroscopic methods as well as comparison with available data in the...

Morinda Pubescens belonging to the family rubiaceae has been reported to posses many medicinal properties according to indigenous system of medicine. The search for biologically active compounds from natural sources has always been of great interest to researchers looking for new drugs useful in infectious disease. In the present study, the various extracts of Morinda Pubescens bark was tested for their antibacterial and antifungal activities against gram positive bacteria such as Staphylococcus aureus, Bacillus cereus, gram negative organisms such as Escherichia coli, Pseudomonas aeruginosa and fungi such as Candida albicans, Aspergillus niger respectively by cup plate method. All the extracts were effective against the tested microorganism which was comparable with standard antibiotics. The ethanolic extract showed highest zone of inhibition then other extracts tested. The zone of inhibition of the extracts of Morinda Pubescens indicating that the plant of Morinda Pubescens can fight these microorganism effectively due to the presence of phenol,triterpinoids and tannins it could be better alternative to the modern...

Madhucalongifolia is an economically important medicinal tree growing throughout the subtropical region. This research article deals with the antioxidant and antimicrobial properties of M. longifolia. The antioxidant properties of the seed were determined by hydrogen peroxide scavenging activity and reducing power assay. The methanol extract exhibited more antioxidant activity than water extract. The fungal and bacterial pathogens used for the study were isolated from the skin scraping of infected animals. The methanol and water extracts of M. longifolia seedswere tested for their antimicrobial efficacy against the pathogens. Methanol extract exhibited good antimicrobial property than water extract. From the above findings it is confirmed that the seeds of M. longifolia posses good antioxidant and antimicrobial...

Background: Prescription of drugs which needs to be continuously assessed and refined according to disease progression. It not only reflects the physician’s knowledge about drugs but also know the pathophysiology of diseases and attitude towards rational prescribing. Methods: Retrospective study was carried out by collecting 350 prescriptions containing antimicrobial agents of the indoor patients admitted in the wards of Paediatric department at Sir Sayajirao General (SSG) Hospital, Vadodara. The data was collected by using case record form specially prepared for the study. Results: In our study, total 350 prescriptions containing 690 antimicrobial agents were prescribed during study period. Average number of antimicrobials per prescription was 1.97. 576(83.48%) and 114(16.52%) antimicrobials were prescribed by using generic name and trade name respectively. 599(86.81%)and 91(13.18%) antimicrobial agents were prescribed for parenteral administration as well as oral route respectively. 101(28.85%) prescriptions constitute single antimicrobial agents, while 249(71.14%) prescriptions contain either two or more than two antimicrobial agents. Among all prescriptions 3 % and 11% of them were without the age and address of...
