Plasmid Profile Of Streptococcus lactis And Lactobacillus Plantarum Isolated From Ogi Encoding For Acetaldehyde In Yoghurt

AbstractAn investigation was carried out on the plasmid profile of Streptococcus lactis and Lactobacillus plantanum isolated from a total of 120 samples collected from Oyingbo, a local market in Lagos State. Morphological, cultural, physiological characterization and API kits were employed to isolate and identify and treptococcus lactis and Lactobacillus plantanum. All the isolates harboured plasmids ranging from 1-7 in numbers and 3kb – 21.5 kb in sizes. Distinct plasmi...

Identification and Characterization of Lactobacillus Isolates Recovered from Locally Fermented Milk (Nunu) consumed within Lagos Metropolis

ABSTRACTThis work assessed the probiotic potential of “Nunu” using Lactobacillus, a genus of Lactic acid bacteria and a major probiotic organism as the indicator. The viable Lactobacillus counts of samples purchased from six different areas within Lagos Mainland were enumerated by serial dilution and pour plating in selective media, DeMann, Rogosa and Sharpe agar (MRS). Twelve strains of Lactobacillus were randomly selected from the samples and identified by standard morphological, physio...

Fine specificity of anti-MSP119 antibodies and multiplicity of Plasmodium falciparum Merozoite Surface Protein 1 types in individuals in Nigeria with sub-microscopic infection

Abstract Background: The absence of antibodies specific for the 19 kDa C-terminal domain of merozoite surface protein 1 (MSP119) has been associated with high-density malaria parasitaemia in African populations. The hypothesis that a high prevalence and/or level of anti-MSP119 antibodies that may inhibit erythrocyte invasion would be present in apparently healthy individuals who harbour a sub-microscopic malaria infection was tested in this study. Methods: Plasma samples were collected...

Potentials of Walnut (Tetracarpidium Conophorum Mull. Arg) Leaf and Onion (Allium Cepa Linn) Bulb Extracts as Antimicrobial Agents for Fish

Abstract The development of antibiotic-resistant pathogens due to the indiscriminate use of antibiotics has led to advocacy for the use of natural products in the treatment of fish diseases. The antimicrobial activity of methanolic and ethanolic extracts of walnut leaves and onion bulbs were evaluated against six pathogenic bacteria (Pseudomonas aeruginosa, Staphyloccocus aureus, Bacillus subtilis, Pseudomonas fluorescens, Escherichia coli, Samonella typhi) using the cup – plate me...

CHANGES IN THE PROTEIN AND FIBRE COMPONENTS OF CASSAVA AND YAM PEELS AFTER SOLID STATE FERMENTATION BY ASPHRCUlIMS NIGER AND RHIZOPUS SP

ABSTRACT Dried, milled cassava and yam peels were inoculated separately with A. nigermidRhizopus sp in solid state. The changes in crude protein (CP), crude fibre (CF), neutral detergent fibre (NDF), acid detergent fibre (ADF) and hemiccllulose were evaluated til 0. 4. X, and 10 days after inoculation. At. the end of the 10th day of fermentation with A. niger the crude protein of cassava peel meal (CPM) increased from 3.5% to 7.0% while that inoculated with Rhizopus sp increased to 5...

Phytochemical Screening and Microbial Inhibitory Activities of Ficus Capensi

ABSTRACT Ficus plant components have application in traditional medicine because of the myriad uses they have been subjected to. The ease of application is based on the secondary metabolites this plant contains. The challenges faced by modern medicine especially in the complete cure of microbially-associated diseases through abrupt and unpredictable genetic mutations in the presence of conventional drugs informed the investigation of the microbial inhibitory activities of the stem, r...

Insecticide Resistance Status Of Anopheles Gambiae Breeding In Stagnant Water Bodies In Lagos, Nigeria

ABSTRACT Anopheles gambiae, the major Afro-tropical malaria vector is resistant to pyrethroid insecticide and this is threatening the impact of malaria control efforts using insecticides. In this study, the major malaria vector species from stagnant water bodies and their susceptibility status to pyrethroid insecticide was determined in some areas of Lagos state, Nigeria. Anopheles larvae were sampled from three areas of Lagos, namely Akoka, Idiaraba and Okobaba and raised to adultho...

16s rRNA Gene Sequencing: A Practical Approach To Confirming The Identity Of Food Borne Bacteria

ABSTRACTOne of the main challenges for clinical practice and public health surveillance is rapid and accurate identification of food borne pathogens. In Nigeria, the use of sophisticated molecular tools for foodborne pathogens detection has not been extensively adopted. Bacterial strains isolated from food products sold in Lagos, Nigeria, were subjected to phenotypic techniques and 16S rRNA gene sequencing for specie level identification. Bacterial identification was performed using colon...

Polymerase Chain Reaction Assay Of Ureaplasma Strains Isolated From High Vaginal Swabs, Of Women In Ibadan, Nigeria

Human Ureaplasma had one species known as Ureaplasma urealyticum but was recently seperated into 2 species

Genital ulcer diseases among HIV-infected female commercial sex workers in Ibadan, Nigeria

ABSTRACTWe evaluated the prevalence and association of Genital Ulcer Diseases among HIV-1 infected female commercial sex workers in Ibadan Nigeria.

Ultraviolet radiation of Schistosoma mansoni. II. Post-hatching radiation effect on some aspects of miracidia behaviour and infectivity

ABSTRACTBatches of Schistosoma mansorti miracidia were irradiated with ultraviolet light for varying time intervals to determine the -influence of radiation on the transmission potential of radiated miracidia. There was a decrease in the survival rate of hatched-free swimming miracidia that corresponded with the increasing radiation exposure time. The activity rate of radiated miracidia also decrease with increasing radiation exposure time, showing a 69.3% reduction in the mean rate ...

Toxoplasma gondii Infection in Free-Range Chicken: Mini-Review and Seroprevalence Study in Oyo State, Nigeria

ABSTRACTFree-range chickens are sentinels for the presence of Toxoplasma gondii oocysts in the environment because they feed from ground. T. gondii infected chickens are also an important source of infection for cats that shed environmentally resistant oocysts after eating infected chicken tissues. We surveyed 50 free-range chickens from Oyo State, Nigeria for the presence of T. gondii antibodies using the modified agglutination test (MAT). All chickens tested seropositive with MAT titers ...

Pattern of Sexually Transmitted Diseases Among HIV-1 Infected Commercial Sex Workers in Ibadan, Nigeria

ABSTBACT This study evaluated the association of HXV-1 infection with some other sexually transmitted diseases (STDs) among femaIe commercial sex workers. BIood samples were collected from 250 female commercial sex workers in Ibadan Oyo State, Nigeria and tested for the presence of HEV antibodies using ELJSA and Western blot. Endocervical and high vaginal swab samples were also collected for microscopy and culture. The prevaIence of HIV-1 infection among CSWs in Ibadan, Nigeria was 25.6...

Candidaemia or Candidasis: Controversy of Staphylococcus Sexually Transmitted Infections

ABSTRACTHerbal medications are becoming increasingly popular but a most-extraordinary claim by traditional/herbal medical practitioners relates to a Gram-positive bacterium, Staphylococcus, which has been depicted as a deadly sexually transmitted disease that manifest in the form of worms and other symptoms; with contributory roles including infertility, sexual dysfunction and impotency. They further boasted that they are the only ones that possessed the remedy (herbal) for the Staphylococ...

Candidaemia or Candidasis: Controversy of Staphylococcus Sexually Transmitted Infection?

ABSTRACT Herbal medications are becoming increasingly popular but a most-extraordinary claim by traditional/herbal medical practitioners relates to a Gram-positive bacterium, Staphylococcus, which has been depicted as a deadly sexually transmitted disease that manifest in the form of worms and other symptoms; with contributory roles including infertility, sexual dysfunction and impotency. They further boasted that they are the only ones that possessed the remedy (herbal) for the Staphyloc...
