Bacteriological Assessment of Polythene Packaged Sliced Watermelon Sold by the Street Vendors in Enugu

ABSTRACT  This research was conducted in Microbiology Laboratory of Godfrey Okoye University to determine the antimicrobial efficacy of aqueous, methanol, ethanol of Pisdium guajava and Citrus x sinensis on the pathogenic Streptococcus mutans and Candida albicans. The Dimethyl sulfoxide was used for dissolving the plant extracts. Pisdium guajava showed antimicrobial activity against C. albicans with the exception of methanol showing no zone of inhibition to any of the isolates. The a...

Nodulation and nitrogen fixation potential of sesbania spp. Rhizobia on sesbania sesban (l.) Merr. And rose coco (phaseolus vulgaris l.)

ABSTRACT Global crop and energy production are fast dwindling inversely to population growth. Common bean (Phaseolus vulgaris L.) yield has reduced worldwide due to soil infertility which can be reversed through application of chemical fertilizers. The chemical fertilizers used to ameliorate nitrogen, phoshorus and potassium are expensive and cause both deleterious physico‒chemical modification of soil and water mass eutrophication. The common bean has ability to fix atmospheric nitro...

Phenotypic And Genotypic Characterisation Of Diarrhoeagenic Escherichia Coli Isolated From Children In Mukuru Informal Settlement, Nairobi County, Kenya

ABSTRACT Diarrhoeal diseases in Kenya are among the five main causes of mortality in children younger than five years. Bacterial diarrhoea has been reported to account for up to 30 % of all cases of infantile diarrhoea. Among children of age five years and below, diarrhoeagenic E. coli (DEC) such as enterotoxigenic E. coli (ETEC), enteropathogenic E. coli (EPEC), enteroaggregative E. coli (EAEC) are the most important enteric pathogens and are responsible for 30 to 40 % of all the diarr...

ANTIMICROBIAL EFFICACY OF GUAVA (Pisdium guajava) AND ORANGE(Citrussinensis) STEMS EXTRACT AGAINST Streptococcus mutans and Candida albicans

ABSTRACT   This research was conducted in Microbiology Laboratory of Godfrey Okoye University to determine the antimicrobial efficacy of aqueous, methanol, ethanol of Pisdium guajava and Citrus x sinensis on the pathogenic Streptococcus mutans and Candida albicans. The Dimethyl sulfoxide was used for dissolving the plant extracts.

Assessment And Characterization Of Rhizobacteria In Petroleum-Polluted Soil In Umuahia

ABSTRACTPetroleum – polluted sites are disturbed ecosystem with scanty plants. Study was carried out in such sites to assess the area of its rhizobacterial status, particularly comparing that of the rhizospheres and non-rhizospheres in the site. The samples were suspended and serially diluted in physiological saline and inoculated on nutrient media by spread plates method. After incubation and isolation, the isolates were characterized by morphological examination, gram staining, biochemica...

Isolation And Identification of Microorganisms From Herbal Mixtures Sold at Enugu Metropolis

ABSTRACT The safety, efficacy and quality of herbal mixtures have been an important concern for health authorities and health professional, especially now there is increase in the use of herbal mixtures. This study was aimed at isolation and identification of microorganisms from some liquid herbal mixtures sold in Enugu metropolis, South East of Nigeria. A total of twenty samples  of herbal mixture were selected at random, from herbal shops in Enugu metropolis and were analysed in M...

Isolation and Identification of Micro Algae from Godfrey Okoye University Fish Pond

 ABSTRACTChlorella vulgaris is an edible microalgae and a highly notorious potential feed resource for many agriculturally important animal species. Chlorella vulgaris intake has also been linked to improvements in animal health and welfare. Its influence over animal development stems from its nutritive and protein-rich composition, thus leading to an increased commercial production to meet consumer demand. The aim of this work is to isolate and identify microalgae used in poultry farmin...

The Anti Hyperglycermic: Effect of Momordica Charantia on Blood Glucose Level of Albino Wistar Rats

The study was carried out to investigate the effect of aqueous and petroleum ether extract of momordica charantia on blood glucose level of albino rats.The extraction was done using petroleum ether and water .Thirty two albino rats were grouped into eight (A ,B,C,D,E,F,G,H). Comprising of four in each group .Diabetes was induced with a single Dose of 100mg/kg body weight of alloxan solution .After induction of alloxan ,group A and B were orally administered with 100 and 200mg/kg body weight o...

The agar well diffusion method was used in study also phytochemical screening was conducted on the plant which revealed the presences of saponin, carbohydrates, tannins the  present inv...

Physicochemical and Phytochemical Analysis of Honey and Shea Butter Samples and Their Antibacterial Effect on Staphylococcus aureus AND Klebsiella pneumoniae

ABSTRACT This research work was carried out to examine the physicochemical and phytochemical constituents of honey and Shea butter samples respectively and their antibacterial effect on Staphylococcus aureus and Klebsiella pneumoniae. The physicochemical screening of honey showed that the honey samples used have low water activity, low moisture content, low pH value below 4.0 and Ash while the phytochemical analysis of Shea butter revealed the presence of Saponnins, Tannins, Alkaloid...

Bactericidal Activities of Hibiscus Sabdarifa Leave Extract against enteric human pathogens

Microbiological  tests  revealed  that  Hibiscus  sabdariffa  plant  extract  has  antibacterial properties  thus  verifying  folklore  medicine  in  the  treatment  of  abscesses,  bilious  conditions, cough,  dysuria  and  scurvy  (Morton,  1987;  Perry,  1980  Ross,  2003).  The  extraction  type  of aqueous  generally  had  the  same  potency  with  cold  extracts  having  a  slightly  better antimicrobial  activity  than  hot  aqueous  ex...
