ABSTRACT               Sponge Callyspongia aerizusa contain potential bioactive compound that can be utilized in the health sector. Extract of sea sponge Callyspongia aerizusa, can hamper the growth of Salmonella typhi bacteria, Streptococcus pyogenes, Shigella and Staphylococcus epidermidis. The aim of this study was to test the antibacterial activity against Escherichia coli and Staphylococcus aureus bacteria and identify the type of symbionic bacteria of Callyspongia aerizusa sponge based on their physiological and biochemical characteristics. The method of testing the antibacterial activity was agar diffusion method (Kirby and Baurer diffusion disc). There were three bacterial isolates namely T1, T2, and T3 isolates. The result showed that T1, T2, and T3bacterial isolates had antibacterial activity against Escherichia coli and Staphylococcus aureus test bacteria. Based on the biochemical test, T2bacterial isolates were identified as Bronchothrix bacteria and T1and T3 bacterial identified as Desulfotomaculum. Keywords: Callyspongia aerizusa, Antibacterial activity, symbiont bacteria, Biochemical Identification   ABSTRAKSpons Callyspongia aerizusa memiliki kandungan senyawa bioaktif potensial yang dapat dimanfaatkan dibidang kesehatan.

Bacteria of the genus Thermoactinomyces have the ability to produce antibacterial bioactive compounds. This bioactive compound can be used for combating diarrheal agents such as Escherichia coli and Staphylococcus aureus. This study aims to determine the antibacterial activity of the metabolite extract from Thermoactinomyces sp. (H24) against Escherichia coli and Staphylococcus aureus. Methanol was used as a solvent for the extraction of bacterial bioactive compounds. Antibacterial activity was analyzed by the diffusion method with several extract concentrations (0.75 mL, 1.5 mL, 2.25 mL, and 3 mL), 10% DMSO as the negative control, and ciprofloxacin as the positive control. Our result shows that Termoactinomyces sp. (H24) extract has an inhibitory effect on the growth of  E. coli and S. aureus with an effective concentration of 2.25 mL (inhibition strength: very strong).

A series of Ferrocene Schiff bases derived from glycine and their cobalt (II), copper (II), nickel (II), and zinc (II) metal complexes have been synthesized and characterized by IR, 1H NMR, MS and elemental analysis, the results conformed well with expected structures. The synthesized ligands, along with their metal (II) complexes, were screened in vitro for their antibacterial activity against three Gram-negative (Escherichia coli, Pseudomonas aeruginosa, and Salmonella typhi) and two Gram-positive (Bacillus subtilis and Staphylococcus aureus) bacterial strains. The results showed that the metal (II) complexes are more potent in antibacterial activity against one or more species in comparison with those of uncomplexed ligands.

Aim: To assess the antibacterial activity of crude honey obtained from Ishielu Local Government of Ebonyi State on pathogenic bacterial species (Staphylococcus aureus, Escherichia coli and Staphylococcus pyogenes) isolated from wounds. Study Design: An experimental study which involved a random selection of patients with wound Place and Duration of Study: Department of Medical Laboratory Science, Ebonyi State University, Abakaliki, Nigeria, between February 2019 and November 2019. Methodology: A total of 50 samples of wound swabs collected from different sites of open wounds were cultured on blood agar, chocolate agar and MacConkey agar. The crude honey was diluted to concentrations ranging from 20% to 100% and the antibacterial activity was carried out by well diffusion method with augmentin used as a control. Result: Out of the 50 samples, 43 showed growth of bacterial species isolated, identified and confirmed using standard bacteriological techniques. Staphylococcus aureus (60.5%) was the most frequent isolates, followed by Escherichia coli (27.9%) and Streptococcus pyogenes (11.6%). All the tested bacterial isolates were susceptible to the honey and the number of isolates as well as the diameter of zone of inhibition was positively linearly correlated with increasing concentration of the honey (p= 0.00). At 100% honey, 22 (22.25±0.46 mm) out of 26 Staphylococcus aureus were susceptible as against 8 (4.62±0.31 mm) at 20% honey.  The number of Escherichia coli inhibited at 20% honey was 2 (1.96±0.04 mm) out of 12 isolated and at 100%, 7 (19.17±0.31 mm) were inhibited. At 20% honey, no Streptococcus pyogenes was inhibited and at 100%, 4 (21.84±0.15 mm) out of 5 isolated were inhibited. Conclusion: Locally produced crude honey may be used as a source of an effective antibacterial agent for wound management.

Azadirachta indica (Neem) is an herbal plant widely distributed in our subcontinent during all seasons. This study was carried out to detect the effect of Azadirachta indica (Neem) leave extract on some selected bacteria. The prospective study was carried out during the period of July 2005 to June 2006. Micro-organisms which are commonly responsible for infection in our country such as Staphylococcus aureus, Salmonella typhi, Escherichia coli and Pseudomonas aeruginosa were considered. Extract of Neem leave that is Aqueous Neem leave extract (ANLE) was prepared by filtration and evaporation. Effect against bacteria was examined by detection of minimum inhibitory concentration (MIC) by using ‘Broth dilution method’ and by detection of bacterial susceptibility by ‘Agar disc diffusion method’ and compare with cefepime. For ANLE the MICs against Staphylococcus aureus, Salmonella typhi, Escherichia Coli and Pseudomonas aeruginosa was 800 μg/ml, 1200 μg/ml, 1400 μg/ml and 1400 μg/ml respectively. With those MICs the average diameter of zone of inhibition against staphylococcus aureus with ANLE and cefepime was 20mm and 30mm respectively. Salmonella typhi exhibit sensitivity with zone of inhibition of 19mm, 26.5mm against ANLE and cefepime. Escherichia coli were sensitive against ANLE and cefepime with 17.5mm, 23.5mm zone of inhibition respectively. For Pseudomonas aeruginosa zone of inhibition was 16mm, and 21mm by ANLE, and cefepime respectively. Aqueous Leave extract of Azadirachta indica (Neem) have antibacterial activity against ‘staphylococcus aureus, salmonella typhi, Escherichia coli and Pseudomonas aeruginosa’ compared with Cefepime. Among all test bacteria staphylococcus aureus has lowest MICs.
