- Phytochemical and antibacterial investigations of moringa (Moringa
oleifera) leaf extract on selected bacterial pathogens
Abstract: This study aimed at evaluating the health benefits of popular Moringa oleifera leaf. The aqueous and methanolic extracts of the leaf at two different concentrations (1:1 and 1:2) was used to determine the phytochemical screening and its antibacterial activity. Escherichia coli, Streptococcus pneumonia and Staphlococcus aureus were used in this study, applying agar diffusion methods. The phyt...

- Phytochemical screening and antifungal activities of
extracts of red-flowered silk cotton tree (Bombax buonopozense) and
Calabash nutmeg (Monodora myristica) on Candida albicans
Abstract: The study was to determine the phytochemical compounds and antifungal activity of the extracts of the leaves, root, bark and seeds of Calabash nutmeg (Monodora myristica) and red-flowered silk cotton tree (Bombax buonopozense). The phytochemicals were extracted and analyzed using standard methods and the antifungal activity of the ethanolic extracts determined with clinical isolates of Candi...

- Antimicrobial compounds produced by Enterococcus spp. isolates from fecal
samples of wild South American fur seals
Abstract: The aims of this study were to identify bacteriocinogenic activity in 13 enterococci isolated from fecal samples of wild South American (Arctocephalus australis) and Subantarctic fur seals (Arctocephalus tropicalis); to determine the physicochemical characteristics and antimicrobial spectrum of antimicrobial compounds against Gram-positive and Gram-negative bacteria; and to evaluate the pres...

- Antimicrobial activity of Bacillus cereus: Isolation, identification and
the effect of carbon and nitrogen source on its antagonistic activity
Abstract: The present study is concerned with the taxonomy and influences of some cultural conditions on growth and antimicrobial metabolite production of a strain of Bacillus cereus, isolated from Albaqa, Jordan, and designated NBS1, which is a highly active against a variety of Gram positive bacteria, and less activity was noted against filamentous fungi and yeasts, whereas no activity was detected ...

- Bacterial load and antibiotic susceptibility pattern of isolates in
operating rooms at Hawassa University Referral Hospital, southern Ethiopia
Abstract: Microbial contamination of air in the operating theatre (OT) is considered to be a risk factor for surgical site infections (SSI) and quality of air can be considered as a mirror of the hygienic condition of these rooms. This study intended to determine the bacterial load and antibiotic susceptibility pattern of isolates in OT indoor air of Hawassa University Referral Hospital. A cross secti...

- Probiotic properties of lactic acid bacteria isolated from fermented sap
of palm tree (Elaeis guineensis)
Abstract: The commonly used probiotics bacteria are lactic acid bacteria (LAB) from gastro intestinal tract. However, other LAB from exogenous origin having similar functional properties may also confer health benefit to the host. Palm wine has been described as a rich source of LAB. But very few studies have investigated their probiotic potential. Twenty LAB were isolated from palm wine collected in ...

- Antimicrobial activity and phytochemical screening of the fruit pulp of
Dialium guineense (Velvet Tamarind) on some microbial isolates
Abstract: The antimicrobial activities of the aqueous, ethanol and n-hexane fruit pulp extracts of Dialium guineense were evaluated against clinical isolates of Klebsiella pneumonia, Staphylococus aureus, Escherichia coli, Pseudomonas aeruginosa, Proteus mirabilis and Candida albicans using the agar well diffusion technique. The results reveal that the crude aqueous and ethanol extracts possess antimi...

- In vitro evaluation of virulence factors of Candida species isolated from
Abstract: The yeast Candida is a normal flora of the skin and the mucous membrane and it then becomes pathogen in immunocompromised people. Various virulence factors are contributing to establishment of the infection in the host. Adherence of the pathogen to host tissues, yeast-hyphal transition and extracellular hydrolytic enzymes secretion are important virulence factors of Candida species. These hy...

- Identification and genotypic analysis of Streptococcus pyogenes isolated
from pharyngitis and tonsillitis infected children in IBB city in Yemen
Abstract: Streptococcus pyogenes is beta-hemolytic bacterium that belongs to Lancefield serogroup A, also known as group A streptococci (GAS). GAS causes a wide variety of life threatening diseases including pharyngitis and tonsillitis disease. A total of 93 throat swab and 93 blood specimens were collected from pharyngitis and tonsillitis infected children in different schools in Almashana, IBB city ...

- Antimicrobial activity of endophytic fungi isolated and identified from
salt marsh plant in Vellar Estuary
Abstract: The purpose of this work was to evaluate the antimicrobial potential of endophytic fungi isolated from leaves and stems of Suaeda maritima and Suaeda monoica. Many endophytes were isolated by using potato dextrose agar (PDA) medium. All the endophytic isolates were identified by using standard taxonomic keys and monographs. From a total of 16 isolates, nine potent strains were taken for furt...
