Antimicrobial Activity of Nigella sativa Seeds Extract Against Carbapenem and Colistin Resistant Gram Negative Bacilli in Khartoum State

Abstract Introduction: One of the most serious issues in medicine is increasing resistance of Gram negative bacilli to antimicrobial agents especially broad spectrum antibiotics such as carbapenems and colistins. This fact is associated with higher mortality and morbidity rates, prolonged hospital stays and increased treatment related costs.Medicinal plants appeared to be the best alternative source for new antimicrobial drugs.. Nigella sativa is an herbaceous plant whose seeds have beenused ...

In Vitro Antibacterial Activity Of Acacia Nilotica (Algarad) Methanolic And Aqueous Extracts Against Wound Pathogens

Do marine phytoplankton follow Bergmann’s rule sensu lato?

ABSTRACT Global warming has revitalized interest in the relationship between body size and temperature, proposed by Bergmann’s rule 150 years ago, one of the oldest manifestations of a ‘biogeography of traits’. We review biogeographic evidence, results from clonal cultures and recent micro- and mesocosm experiments with naturally mixed phytoplankton communities regarding the response of phytoplankton body size to temperature, either as a single factor or in combination with other facto...

Assay Of Antibiotic Producing Microorganisms From Different Soils In The Premises Of Federal University Oye-Ekiti, Ekiti St A Te. (Fuoye)

ABSTRACT A total of eight soil samples were collected from different sites within FUOYE environment and were analyzed to determine the presence of antibiotic producing bacteria, fungi and actinomycete Using nutrient agar, sabauraud dextrose agar and glycerol yeast extract agar as culture media. Seven bacteria: Escherichia coli, Bacillus spp, Pseudomonas spp, Azomonas spp, Gluconobacter spp, Micrococcus spp, and Staphylococcus aureus; five fungi: Rhizopus spp, Mucor spp, Rhodotorula spp, ...

Detection Of Bioactive Compounds By Bioautography Of Diodia Scandens On Staphylococcus Aureus And Coagulase Negative Staphylococcus

ABSTRACT Plant samples collected within and around Federal University Oye-Ekiti was air dried, pulverized and subjected to hot (soxhlet) extraction and cold extraction using three (3) extractive solvent (ethyl acetate, methanol, n-hexane).' The extracts were seperated from the solvent using rotary evaporator while the crude extracts were subjected to thin layer chromatography (TLC) using different solvent ratio mixtures on a silica gel coated TLC plates. The antibacterial activity of act...

Detection Of Bioactive Constituents In Phyllanthus AmarUs Using Thin Layer Chromatography-Bioautographic Method Against Staphylococcus Aureus And Coagulase Negative Staphylococcus AUreUs

ABSTRACT Medicinal plants have been used for centuries as remedies for human diseases because they contain components of therapeutic value. Phyllanthus amarus has shown to work as an antifungal, antibacterial and antiviral agent. Bioautography is a technique used to isolate compounds by employing a suitable chromatographic process followed by a biological detection system. Referenced pure culture antibiotics resistant Coagulase Negative Staphylococcus strain (Co NS I Ob: Ojo) and Staphyl...

Prevalence Of Human Papilloma Virus (Lgm) Antibody Among Fuoye Student

ABSTRACT Human papilloma virus (HPV) infections are the most common sexually transmitted infections(STDs) in the world. This study was to document the prevalence. of Human papilloma virus infection in Federal university Oye-Ekiti, Ekiti State, Nigeria. Urine samples were collected from ninety four participants and were screened for HPV (lgM) antibody using the HPV ELISA. Out of 94 samples analysed, 2 (2.1 %) was positive for Human papilloma virus IgM, and higher prevalence were recorded i...

Isolation And Identification Of Microorganisms Associated With Grounded Palm Kernel Shells Using Chicken Droppings As Innoculum At . Ratio 2:1.

ABSTRACT This research study is designed to determine the microbial count of Chicken Droppings and Ground Palm kernel shell in which the chicken droppings is used as inoculum on Ground Palm Kernel Shell at Ratio 2: l in which the inoculum size is half of the Ground Palm Kernel Shell. Pollution of the environment due to oil production can be reduced through this study because is aimed at examining the microorganism responsible for the biodegradation that can be achieved in Palm kernel she...

PROPHYLACTIC ACTIVITY OF Phyllantlms Amarus And Diodia Scandens IN SYNERGISM O SWI S ALBINO RATS

ABSTRACT This study is aimed at evaluating the proP,hylactic activity of Phy/lanthus amarus and Diodia scandens in synergism on the Swiss albino rats. The two plants were obtained from Federal University Oye-Ekiti and its environs, thoroughly washed with distilled water and air dried at room temperature for two weeks. The air dried plant materials were pulverized into powdery form using house-hold electric blender. Ethyl-acetate extracts of the two plants combined was administered orally in ...

Prevalence Of Malaria Among Patients With Sickle Cell Trait In Ekiti State

ABSTRACT This study was carried out to determine the prevalence of malaria parasite among patients with sickle cell trait in Ekiti state. A total of 20 samples were collected from different hospitals and clinics. The samples were collected randomly and sodium metabilsulphite was employed to confirm the sickling trait in the samples and thereafter the malaria parasite kit was used to test for the prevalence of malaria in the samples. Eight (8) persons who tested positive for sickle cell trait...

Antibiotic Susceptibility Pattern Of Aerobic Mesophilic Bacteria Isolated From Kunu Samples Sold In Ile-Ife, Osun State, Nigeria.

ABSTRACT The antibiotic susceptibility pattern of aerobic mesophilic bacteria isolated from kunu samples sold in Ile-lfe, Osun State, Nigeria was studied following standard microbiological methods. Seven ready-to-drink kunu samples were purchased from different hawkers at Ile Ife. The samples were transported immediately in ice bucket to the laboratory for analysis. The aerobic mesophilic bacteria associated with kunu samples were isolated, labeled and identified by phenotypic and biochemica...
