Natural biopolymers as lignin, a common plant biopolymer, look interesting antimicrobial agents against the pathogenic microorganisms. This study aims to produce eco-friendly products by extracting lignin from two Egyptian cotton cultivars, Giza 86 and 90, using organosolv technique transferring them into nanoparticles then determine bioactivities treat textiles for medical applications seven h...

Certain serovars of Salmonella enterica subsp. enterica cause invasive disease (e.g., enteric fever, bacteremia, septicemia, meningitis, etc.) in humans and constitute a global public health problem. A rapid, sensitive diagnostic test is needed to allow prompt initiation of therapy in individual patients and for measuring disease burden at the population level. An innovative and promising new r...

The antibacterial activities of the methanolic leaf and bark extract of Persea americana was tested in vitro on bacterial isolates namely: Streptococcus pyogenes, Proteus mirabilis, Salmonella typhi, Klebsiella pneumoniae, Escherichia coli, Bacillus subtilis (NCIB 3610), Staphylococcus aureus (NCIB 8588), Escherichia coli (NCIB 86), Klebsiella pneumoniae (NCIB 418) and Pseudomonas aeruginosa (N...

A one year study (August 1998-July 1999) of bacteremia in febrile children was carried out in the Medical Unit (III), Yangon Children's Hospital (YCH), Myanmar, to determine: (1) the bacteria responsible for fever of five days or more in children; (2) the antibiotic sensitivity pattern of these bacteria. Children aged one month to 12 years who had fever for five days or more and who did not rec...

OBJECTIVE To study the in-vitro antimicrobial activity of Cefpirome: A new fourth generation Cephalosporin in comparison with other agents against clinically significant Gram-negative and Gram-positive bacteria. SETTING A multi-center in-vitro study was conducted in 13 centers. MATERIALS AND METHODS Bacterial isolates--A total of 1300 isolates were collected from different clinical laborato...

In vitro antibacterial activity of methanol, ethanol, and ethyl acetate extracts of raw and processed honey was tested against Gram-positive bacteria (Staphylococcus aureus, Bacillus subtilis, Bacillus cereus, Enterococcus faecalis, and Micrococcus luteus) and Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa, and Salmonella typhi). Both types of honey showed antibacterial activi...

In the present investigation of the human pathogenic bacteria such as Escherichia coli, and Pseudomonas fluorescens, Salmonella typhi, and Klebsiella pneumoniae, were analysed the ozone treatment by using ozonizer M221. To optical density was control and treated cultures were measured and to the different time intervals such as 5, 10 and 15 minutes of the optical density (by use of a digital sp...

A study was carried out to investigate the potential of using aqueous infusion, decoction and essential oil of clove (Syzygium aromaticum) as natural antibacterial agents against 100 isolates belonging to 10 different species of Gram –ve bacilli viz., Escherichia coli (36), Proteus mirabilis (6), Pseudomonas aeruginosa (10), Enterobacter aerogenes (5), Klebsiella ozaenae (2), Klebsiella pneumon...

Hexane, petroleum ether, chloroform, ethyl acetate, acetone and methanol extracts of Tulsi (Ocimum sanctum) were analyzed for determination antibacterial activity against enteric-pathogenic bacteria Escherichia coli, Shizella dysenteriae, Salmonella typhi, Pseudomonas aeruginosa Vibrio cholerae using agar well diffusion method. Only extract all them exhibited an inhibiting effect on the develop...

OBJECTIVE Sea urchin gonad is considered as a highly prized delicacy in several countries. It is also rich in valuable bioactive compounds including polyunsaturated fatty acids (PUFAs) and β-carotene. This study was undertaken to examine the antimicrobial properties of the ovary extract from sea urchin Diadema setosum against selected Gram-negative and Gram-positive bacteria. MATERIALS AND ME...
