Abstract

Antibacterial screening of the crude extracts of Indigofera longeracemosa were tested against seven important human pathogenic bacterial strains including gram-negative such as Escherichia coli, Klebsiella pneumoniae, Salmonella typhi, Vibrio parahaemolyticus, Vibrio cholerae and gram–positive namely Bacillus subtilis and Streptococcus pneumoniae. The results highlighted that most of the bacterial species exhibited better growth inhibitory activity. Aqueous and hexane extracts exhibited good antibacterial properties than other two extracts. Furthermore studies pertaining preliminary phytochemical and pharmagonostic analysis have been investigated.

Abstract

The present study pertains the isolation of aerobic microorganisms from wound infection and to study its antibiogram. From the collected 20 wound samples 10 isolates were identified. Pseudomonas aeruginosa (24%) was the predominant isolate followed by Staphylococcus aureus (20%) and Escherichia coli (20%). Antobiogram study reveals that all the isolates were sensitive to Ciprofloxacin and Sporidoxin.

Keywords

Abstract

The frequently changing of ecological condition demands for developing ecofriendly herbal antimicrobial agents. The present study was under taken to evaluate the antimicrobial activity of ethanolic leaf extract of Neem leaf and flower extracts of Nochi against phytopathogens, Xanthomonas and Fusarium. All plant extracts showed considerable antibacterial activity against Xanthomonas and antifungal activity against Fusarium. The results showed that the leaf extract of Neem had high toxicity against tested pathogenic organisms, the antimicrobial activity of other extract increases with increasing concentration of extracts.

Keywords
