Resistance to pathogenic bacteria may lead to serious health problems. Scientists found that discovering novel antimicrobial compounds is possible by exploring rarely investigated environments. Therefore, this work focused on isolating and identifying some fungal strains collected from the Co To sea. We tested whether such strains can produce compounds with vital activities, including antibacterial and antifungal. The antimicrobial activity of the marine fungi crude extracts was performed by the Bioassay method in a 96-well tray.

The present investigation was undertaken for in vitro screening of antibacterial activities of different extracts (ethyl acetate, methanol and benzene) of various plant parts of Achyranthes aspera, Azolla pinnata, Cissus quadrangularis. In vitro antibacterial efficacy of plants selected was assessed by well diffusion method against pathogenic bacteria such as Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli. The ethyl acetate extract of Cissus quadrangularis exhibited highest zone of inhibition against S. aureus (25±1.3mm) followed by Achyranthes aspera (20.0±0.

Antibacterial activities of Black pepper fruit extract were studied against some bacterial strains as- Pseudomonas fluorescens, Pseudomonas aeruginosa, Klebsiella pneumoniae, Proteus vulgaris, and Bacillus subtilis. The black pepper fruit extracts were prepared in four organic solvents as methanol, ethyl acetate, chloroform and benzene. Effectiveness against bacterial strains showed by all extract (which prepared by organic solvent) but the benzene extract showed the maximum growth inhibition 81.20% against Klebsiella pneumoniae bacteria at 100µl/ml extract concentration.

The study was to investigate the antibacterial activity of some medicinal plants against Urinary Tract Infection (UTI) causing pathogens. Bacteria isolated from the UTI infected patients were characterized by microscopic, staining and morphological and biochemical evaluations. Crude extracts of the selected medicinal plants prepared were checking their antibacterial activity against the bacteria isolated from UTI infected patients. The zone of inhibitions was compared with the zone of inhibition of standard antibiotics.

In the present investigations, whole body extract of earthworm, Eisenia fetida was tested for antibacterial activity against fish bacterial pathogens. The bacteria were isolated from different tissues of infected common carp, Cyprinus carpio and identified by gram staining method. A total of eight pathogenic bacteria were isolated. Antimicrobial activity of the extract was studied under in vitro conditions by well diffusion assay.
