Extended Spectrum Beta-lactamase Genes in Clinically Important Bacteria Isolated from Wastewater of Two Selected Tertiary Hospitals in Enugu, Nigeria

Agbo O. A.*, Momoh M. A.

Hospital activities have resulted in increased discharge of untreated effluent into the environment, posing substantial risks to public health and the environment due to the presence of diverse harmful components, including extended spectrum β–lactamase (ESBL) producing bacteria harboring resistance genes, which are adding to the global crisis of antimicrobial resistance (AMR). This study aimed...

Antibiotic Susceptibility Pattern of Bacterial Species Isolated from Selected Underground Water Bodies in Ohaukwu Metropolis, Ebonyi State, Nigeria

Awoke O. O.*, Edeh P. A., Ekuma U. O, Ituma M. A, Awoke C. U, Anene C. C, Onwa, N. C

Infections caused by using contaminated water are common in developing nations. Indiscriminate use of antibiotics has led to increased spread of antibiotic-resistance bacteria, even in underground water. This study investigated the susceptibility pattern of bacterial isolates from borehole water and hand-dug wells in Ohaukwu, Ebonyi State, Nigeria. Twenty (20) water samples were collected at r...

Pathogens Effects of Herbicides (Atrazine, Gramaxone and Glyphosate) on Soil Physicochemical and Microbiological Properties

Jafaru M. I.*, Doughari J. H, Mohammed, A.

The studies on the effects of the herbicide (atrazine, glyphosate and gramaxone) on soil physico- chemical properties was carried out between the months of August 2022 to January2023. Two sites forest and a garden were selected in Federal Polytechnic Mubi, Adamawa State, Nigeria using randomized complete block design (RCBD). The herbicides had significantly increased the amounts of soil organic...

Screening and Optimization of Biosurfactant Production by Bacillus subtilis from Restaurant Wastewater Contaminated Soil

John W. C.*, Joshua V. I, Ihum T. A., Sikiru G. K, Dinchi P. T., Ishaya M.

Biosurfactant production from Bacillus subtilis RT9(4)B isolated from restaurant wastewater contaminated soil was investigated. The isolated Bacillus subtilis RT9(4)B was screened for biosurfactant production using the emulsification index, oil displacement, zone of haemolysis, surface tension and a positive drop collapse method. Effects of carbon and nitrogen sources, pH, temperature and incub...

Microbiological Quality of Sediment and Water Samples from Selected Surface Waters in Anambra State, Nigeria

Okaa A. I.*, Ogu C. T., Chukwujekwu A. G

Water occupies about 70% of the earth’s surface and is one of the most demanded of all urban and rural amenities, thus indispensable for human activities. Microbiological properties of water and sediment samples from four surface waters in Anambra state Nigeria were investigated for the evaluation of their pollution level. A total number of twenty (24) samples, with three (3) samples per sampli...

Heavy Metals Sludge from Septic Tank Sewage: Implication for Use as Fertilizer

Oyem I. M*, Oyem H. H.

Sludge contains nutrients, heavy metals, and metalloids some of which are essential macronutrients, such as N, P, K, Ca, Mn and other essential trace elements, such as Cu, Fe and Zn. This paper examines the heavy metals within the septic tank system and their eventual accumulation as components of sludge with implication for agricultural use. Sludge samples from the inlet and outlet chambers o...

Evaluation of Probiotic Properties of Lactic Acid Bacteria Isolated from Some Fermented Foods

Abdulsalam, R.*, Bala, J.D, Abalaka M. E, Ocheme O. B

Probiotics are live microorganisms which when consumed in adequate quantity; promote the health of the consumer. This study was carried out to evaluate probiotic properties of lactic acid bacteria (LAB) isolated from fermented foods (wara, ogi, orange juice, pickles, sauerkraut and grape juice). A total of eighty four isolates were identified as LAB species by morphological, Gram staining and s...
