Purpose: Neonatal sepsis, a major killer among neonate, necessitates urgent implementation of empirical therapy and later specific antimicrobial therapy against causative microorganism. Empirical therapy relies upon data obtained from previous studies. We conducted this study to evaluate the blood culture, sensitivity and resistance pattern of various antimicrobial agents in neonatal sepsis at Neonatal Intensive Care Unit at a tertiary care hospital in western part of India, which will show us the changing pattern of etiological organism and antimicrobials needed to curb them. Methods: We conducted a prospective cross sectional study over a period of six month duration in Neonatal Intensive Care Unit at tertiary care hospital. We collected and analyzed the blood culture reports and sensitivity pattern of antimicrobials used. Results: We enrolled 163 patients of neonatal sepsis. Paediatricians sent 163 blood samples for culture of which 62 % culture were positive. Out of 101 positive cultures 70 % were Gram negative organisms. Most frequently encountered organisms were Klebsiella Pneumonia followed by Acinobacter species while least common was Coagulase...

Medicinal plants are of important therapeutic aid for various treatments. Leucas cephalotes Spreng. up in cultivated fields as a weed, especially after a period of rain. In the present study the dried plant stems powder of Leucas cephalotes Spreng. was taken and subjected to extraction with ethanol and aqueous extraction was done on the marc left after ethanolic extraction. The antimicrobial activity in terms of zone of inhibition and minimum inhibitory concentration of different extracts of Leucas cephalotes Spreng.. was tested against three bacterial strains viz. Staphylococcus aureus, Escherichia coli, Vibrio cholera and two fungal strains viz. Candida albicans, Aspergillus niger. The zone of inhibition was determined for these pathogenic microorganism by using specific standards and respective controls for determining Minimum inhibitory Concentration (MIC). The ethanolic extract showed more activity against S. aureus and others bacterial/fungals strains than the aqueous extract. It was concluded that the ethanolic extract of the plant Leucas cephalotes Spreng. was more active against all the test strains than the aqueous...

Heterocyclic compounds are well known for their different biological activities like anti-inflammatory, antibacterial, antifungal, anticancer, insecticidal, pecticidal, antibiotic, etc. the versatile applications of oxygen, nitrogen and sulphur containing heterocyclic compounds have made this area of extensive research. The present study deals with the synthesis of some new 3-(2′-hydroxy-3′-nitro-5′-methylphenyl)-5-(aryl/heteryl) pyrazoles synthesis from 1-(2′-hydroxy-3′-nitro-5′-methylphenyl) – 3 – aryl/heteryl – 2-propen-ones i.e. chalcone by reaction with hydrazine hydrate in ethanol and synthesized compounds screening for antimicrobial...

Cyclocondensation of 5-6 and 7-8 with chloroacetyl chloride in presence of triethylamine give 9-10 and 11-12 respectively. All the synthesized compounds 1-12 have been screened for their antibacterial as well as antifungal activities and compared with reference drugs streptomycin and fusidic acid respectively. These synthesized compounds were screened for their antibacterial activity against S. aureus and B. subtillis and antifungal activity against A. niger and C. albicans. The melting points were determined in open glass capillaries tubes. Purity of the compounds was checked by thin layer chromatography (TLC) on silica gel G plates and spots were located by using iodine chamber. All the newly synthesized compounds were confirmed by elemental (C, H, N) and spectral IR, 1HNMR analysis. In this series compound 10 showed better antibacterial activity than reference drug streptomycin and compounds 10 and 12 were found to be more potent antifungal agents than reference drug fusidic...

Emergence of resistant bacterial and fungal strains towards existing antimicrobial agents is one of the major motives for research and development of new molecules to defend them. Oxadiazole is a major compound of heterocyclic nucleus for the development of new drugs. Oxadiazole ring system could be incorporated into many more ring systems which itself have their own activity and could lead to potent and highly active compounds. In silico is an expression used to mean “performed on computer or via computer Simulation”. Docking is a method used to identify the fit between a receptor and a potential ligand. In this research work In silico design of 2,5-disubstituted 1,3,4-oxadiazole derivatives were carried out by Schrodinger software for antimicrobial activity. The antibacterial and antifungal proteins were selected from Protein Data Bank and docked with hundred derivatives of 2,5-disubstituted 1,3,4-oxadiazole by using glide XP. Then five derivatives with highest glide Score were selected and synthesized. Synthesis was a microwave cyclisation reaction between hydrazide and various aromatic acids. The newly synthesized derivatives were...
