Low Incidence of Extended Spectrum Beta Lactamase (ESBL) Detection From Enterobacteriaceae Isolated From Pig Faeces

Itaman, V.O*, Nwankwo Emmanuel Omvubiko, Erhunmwunse, A.S, Adeleye, LA

This study assessed the low incidence of ESBL detect and associated antimicrobial/antibiotic resistance from Enterobacteriaceae isolated from pigs. A total of twenty-six (26) isolates from the forty-five (45) faecal piggery samples studied were Gram negative bacteria which were further characterized using standard biochemical procedures as : Citrobacter freundii 7(26.9%), E. coli 5(19.2%), Klebsie...

Effect of Nitrogen Sources on Crude Oil Utilization by Mangrove Bacterial Strains

Nwanyanwu, C. E*, Adieze, Ifechukwu E., Nwauzor, A.R.

Batch experiment was conducted to investigate the effect of nitrogen source on biodegradation of crude oil by hydrocarbon utilizing bacteria isolated from Eagle Island mangrove ecosystem of Niger Delta, Nigeria. The organisms were identified as Pseudomonas sp. MW3 and Bacillus sp. SD4. The ability of the organisms to solubilize crude oil was indicated by having emulsification index values of 62.1,...

Profiles of aflatoxin biosynthetic key genes in non aflatoxigenic Aspergillus flavus isolated from in-process wheat flour from parts of Northern Nigeria

Wartu, J.R.*, Whong, C.M.Z, Abdullahi, I.O, Ameh, J.B

Aflatoxigenic molds are strains that produce aflatoxins. This study used yeast extract sucrose agar supplemented with 0.3% beta methyl cyclodextrin and 0.6% sodium desoxycholate to differentiate between aflatoxigenic and atoxigenic strains. ELISA and multiplex PCR techniques were also employed to assess aflatoxin production and detect key aflatoxin genes (aflR-1, omt-A, ver-1, nor-1). Isolates 1, ...

Citric Acid Production by Aspergillus niger using cane Molasses as Substrate

Baba, J.*, Mohammed S.S.D., Ayansina A.D.V, Shaba A. M., Innocent B

Citric acid production by Aspergillus niger isolated from spoilt beans using cane molasses was investigated. The spoilt bean on SDA media produced Aspergillus niger from which Citric acid was produced using submerged fermentation technique. The sensory properties of the Citric acid produced from A. niger indicated dark coloration with pH values of 3.55 as the minimum and 5.19 as the maximum. The t...

Isolation and Identification of Coliform Bacteria from Selected Well Water in Lapai Metropolis, Niger State, Nigeria

Baba, J.*, Majiya, H. M, Muhammad, I. L, Abdullahi, M, Oladoke, A.B.

The study was carried out to isolate and identify Coliform bacteria from well water situated in Lapai metropolis. Fifteen (15)samples of well water, used for domestic purposes were collected from different well water points within Lapai metropolis. Most Probable Number was used for enumeration of Coliform, Cultured on Nutrient agar and Eosin methylene blue (EMB) Agar. The isolates were subjected t...

Microbial Assessment of Ready-to-Eat Fried Grasshopper Sold in Jos and its Environs

Dawang, D.N*, Gogwim, F. T

Food is an important basic necessity but its procurement, preparation and consumption are vital for the sustenance of life. Unfortunately it is also a vehicle of disease spread. The aim of this research is to determine the microbial quality of ready- to- eat grasshoppers being sold within Jos and its environs. Two hundred (200) samples were purchased from 10 different locations within Jos and its ...

Microbial Profile In Children With Secretory Otitis Media In Zaria, Nigeria

Ahmad,A. E*, Musa, B. O. P, Jamoh, B. Y., Opaluwa, A. S, Nasir, A. L, Usman, Y

Sixty (60) children with secretory otitis media and 60 age and sex matched controls were recruited for the study. Ear-discharge swabs were taken from children with secretory otitis media and cultured for microbial isolation and identification. Un-paired student t-test was used to compare the difference between the children with secretory otitis media and the control group, while Chi-squared test w...

Isolation of 2,4-Dichlorophenol Tolerant Bacteria in Wastewater Effluent from University of Nigeria Sewage Treatment Plant Site.

Godwin E. Oyiwona*, Chukwudi Uzoma, AnyanwuJ Lewis Ezeogu

Phenol tolerant bacteria were isolated from sewage treatment site. Sixteen bacterial colonies were isolated and tested in 100-500 mg/L of 2,4-Dichlorophenol (2,4-DCP). After screening, two isolates which showed high phenol resistances were selected. Both isolates, XC, and N3 were able to tolerate 200 mg/L of 2,4-DCP but isolate N3 tolerated 400 mg/L of 2,4-DCP. Isolate N3 was identified as Bacillu...
