Antimicrobial activities of selected plants (bitterleaf, utazi, and bitterkola leaf)extracts against fish pathogenic bacteria

Aquaculture has been a growing activity for the last 20 years worldwide and this impressive development has been attended by some practices potentially damaging to animal health. The bacterial infections are considered the major cause of mortality in aquaculture. Among the common fish pathogens, A. hydrophila and Y. ruckeri as gram-negative and S. agalactiae, L. garvieae and E. faecalis as grampositive bacteria cause infectious diseases.

The antibacterial producing properties of Actinomycetes

ABSTRACTThe antibacterial producing properties of Actinomycetes were carried out using soil samples collected from different locations at Osun State University, Osogbo, main campus. The soil samples were collected from twelve (12) diffeferent locations within the study site. The samples were cultured aseptically by inoculating each samples on Starch Casein agar and incubated at 30oC. Identification and characterization were carried out by morphology, microscopic and biochemical tests. The pro...

MICROBIAL QUALITY ASSESSMENT OF LOCALLY PRODUCED KUNU SOLD AT TANKE AREA OF ILORIN METROPOLIS

Nine samples of freshly prepared kunu was taken from local vendors and hawkers at Tanke area, Ilorin, Kara State and analyzed for microbial quality. The pH of the samples ranged from 2.66 to 4.06. The total bacterial count ranged from 1.5×104 to 7.4×104 cfu/ml; the total coliform count ranged from 1.0x102 to 8.0x103cfu/ml; the faecal coliform count ranged from 0 to 3.0x103cfu/ml; the total fungi count ranged from 3.2x104 to 2.7x105cfu/ml. The presence of high microbial load was an indicatio...

ISOLATION, IDENTIFICATION AND ANTIBIOTIC SUSCEPTIBILITY OF Bacillus spp RECOVERED FROM THE HANDS OF APPARENTLY HEALTHY FEMALE UNDERGRADUATE STUDENTS OF OBAFEMI AWOLOWO UNIVERSITY, ILE-IFE.

ABSTRACTThe human hands harbour microorganisms both as part of a person’s normal microbial flora as well as transient microbes acquired from the environment. This study was carried out to isolate and identify Bacillus spp that are associated with the hands of apparently healthy female undergraduate students in Obafemi Awolowo University. The samples were collected using sterile swab sticks dampened into sterile 0.85% normal saline and processed immediately in the laboratory. The isolates we...

Phytochemical Analysis and Antimicrobial Effect of Calotropis procera (Sodom apple) Leaves Extract on Some Bacteria Isolated from Spoilt Nunu Milk.

ABSTRACTThis study was carried to with the aim of determining the antibacterial effect of Calotropis procera against some bacteria isolated spoilt nunu. Bacteria isolated from spoilt nunu were identified based on their Gram characteristics, morphology and biochemical characteristics. Calotropis procera was extracted using ethanol, methanol and distilled water. The ethanol and methanol extracts showed the presence of Saponins, Steroids, Terpenoids, Flavonoids, Tannins, Alkaloids, and Cardiac g...

ANTIMICROBIAL POTENTIAL OF Emericella nidulans AGAINST SELECTED PATHOGENS

ABSTRACT Endophytic microorganisms have proven to be potential sources of antimicrobials against recalcitrant pathogens. Extracts of an endophytic fungus, Emericella nidulans  exhibited antibacterial  activity  against  selected  pathogens.  Emericella  nidulans  was  cultivated  in broth and fermented at 28 ± 2°C for 7days and 21 days to obtain bioactive components. Solvents extraction of bioactive compounds from Emericella nidulans in the ...

PREVALENCE OF METHICILLINE RESISTANCE Staphylococcus aureus FROM THE GASTRO ORIGINAL

Prevalence of Staphylococcus aureus and Escherichia coli from the surface of cockroaches found in the university of Lagos

The Antimicrobial properties and phytochemicals analysis of Basella alba Linn and Talinum trangulaire against some bacteria and fungi

Medicinal plants have provided a source of inspiration for novel drugs compounds since plant derived medicines have made large contributions to human health. The traditional healers make use of water primarily as solvent but extracts of these plants were certainly much better and powerful. This may be due to the better solubility of the active components in organic solvents (Umadevi, 2011).The phytochemical component of the ethanolic extracts of Basella alba leaf revealed the presence of tann...

Microbiological Evaluation in ilorin Metropolis

ABSTRACT            The presences of pathogenic microorganism in ice cream such as Salmonella Species, Staphylococcus aureus, Escherichia coli have been well documented, but examination of pathogenic bacteria like Bacillus cereus Yersinia enterocolitica, Brucella species and E.coli O157:H7 have been rarely studied. These studies indicated the necessity for a more steady microbial examination of ice cream since ice cream is particularly consumed by children of vulnerable age groups. Ice ...

Antimicrobial screening , nutrients profile and Pyhtochemical analysis of the leaf extracts of Tetrapluera tetraptera

ABSTRACTPhytochemical and Antimicrobial activity of the leaves of Tetrapluera tetraptera using aqueous and ethanolic extract was studied. The leave was observed to be highly rich in polyphenols, flavonoid, reducing compounds and alkaloids. Glycosides, saponins and tanins were present in small amount, there was absence of Phlobotanins, anthraquinones and hydroxyl methyl anthraquinones. In order to confirm the exact concentration of the Phytochemicals present in the leave of T. tetraptera, a GC...
