Kocuria: A Potential Problem in Patients with Complicated Urinary Tract Infections

Imanyikwa O. E. E., Ezeonu I. M., Agbo M. C.*

Kocuria species are Gram-positive, catalase positive and coagulase-negative cocci that were not previously associated with human infections; but have recently emerged as human pathogens. These organisms have been implicated in different infections including urinary tract infections (UTIs), mostly in patients with underlying diseases. The aim of this study was to investigate the possible involvemen...

Assessment of Gut Fungi and Haematological Parameters of Patients with Different Blood Glucose Levels in Federal Medical Centre, Yenagoa

Isaiah O. G., Etebu E., Etebu E.*

This study examined gut fungi and haematological parameters in 20 patients with varying blood glucose levels separated into diabetic (≥7.0 mmol/L, n=9), pre-diabetic (5.6-6.9 mmol/L, n=8), and normal (3.9-5.5 mmol/L, n=3) groups. Fungal species and haematological parameters were analyzed using molecular and standard methods. Total fungal populations were comparable across all three groups; mean Lo...

Detection of Antimicrobial Resistance Genes in Alcaligenes faecalis Isolated from Urine Samples of HIV-Positive Individuals

Oladejo B. O.*

Urinary tract infections (UTIs) pose a significant health challenge for individuals living with HIV, often involving opportunistic pathogens with escalating antimicrobial resistance. This study focused on Alcaligenes faecalis isolates recovered from urine samples of HIV-positive individuals attending a selected health facility in Akure, Nigeria. The study employed 16S rRNA gene sequencing for iden...

Antibacterial Activities of Tiger Nuts Extracts against Bacteria Isolated from Diarrheagenic Stools Obtained from Selected Hospitals in Akure, Nigeria

Olalemi A. O., Adetoye A. A.*

Diarrheal diseases remain a global health burden, especially in developing countries where antibiotic resistance complicates treatment. This study investigated the antibacterial activities of n-hexane and ethanolic extracts of tiger nut (Cyperus esculentus) against bacterial isolates obtained from diarrheagenic stool samples collected from selected hospitals in Akure, Nigeria. Stool samples were c...

Prevalence, Antibiotic Susceptibility Profile, and Multiple Antibiotic Resistance Index of Gram-Negative Bacteria Isolated from Skin and Nasal Samples of Goats Bred in Abakaliki, Ebonyi State, Nigeria

Ukpai E. G.*, Okwuonu C. A.

Antimicrobial resistance (AMR) is a critical global public health threat, with food-producing animals recognized as important reservoirs of multidrug-resistant (MDR) bacteria. In Nigeria, indiscriminate antibiotic use and weak regulatory frameworks have exacerbated resistant pathogen spread. Goats (Capra hircus) are widely reared in Abakaliki, Ebonyi State, serving as major meat and income sources...

Cephalosporin, Colistin, and Beta-Lactamase Inhibitor Resistance in Clinical Pseudomonas aeruginosa Isolates: Associations with Patient Age and Gender in a Nigerian Tertiary Hospital

Uzoeto H. O.*, Mohammed I. D., Ukpai E. G., Peter I. U.

Pseudomonas aeruginosa is a leading cause of healthcare-associated infections with remarkable capacity for antimicrobial resistance. This study investigated the resistance profiles of clinical P. aeruginosa isolates, focusing on cephalosporins, colistin, and beta-lactamase inhibitors, and examined associations with age group and gender. A total of 250 clinical samples (150 urine, 100 wound swabs) ...

Optimisation of Lipases from Fungi Associated with Palm Oil Mill Soils

Abiola O. F. A.*

Lipases are industrially significant enzymes applied in food processing, detergents, pharmaceuticals, cosmetics, and biodiesel manufacture. Palm oil mill effluent (POME), though nutrient- rich and supportive of microbial growth, is also a major pollutant of the environment. Exploring lipolytic fungi from such soils provides a dual benefit of waste management and enzyme generation. Soil samples fro...

Biodegradation of Hydrocarbons by Bacillus cereus and Enterococcus casseliflavus Isolated from Crude oil Contaminated Seafood

Akomah-Abadaike O. N.*, Mbolo P. F.

This study aims to determine the biodegradability capacity of Enterococcus casseliflavus and Bacillus isolated from crude oil contaminated seafood. Fresh seafood samples such as crude oil contaminated periwinkle and prawn were obtained. BOD, COD, pH, nitrate, phosphate, heavy metals (Cr, Cd, Pb, Zn), polyaromatic hydrocarbons (PAHs), total petroleum hydrocarbon (TPH} were determined. Standard micr...

Occurrence of Multidrug-Resistant Escherichia coli in Abuja Wastewater Treatment Plant and Wupa River

Stella N Madueke, Ibangha I-A. I., Ozochi A. C., Onyeiwu S. C., Anyanwu C. U., Chigor V. N.*

The discharge of multidrug-resistant bacteria into the environment can promote the transfer of resistance genes to clinically important bacteria, thereby posing a substantial public health risk. This study evaluated Escherichia coli isolated from the Abuja wastewater treatment plant and the Wupa River in Abuja, Nigeria, for multidrug resistance (MDR) and antibiotic resistance genes (ARGs). Isolate...

Evaluation of Chicken Feathers Degraded by Keratinase for Poultry Feed Supplement

Okediji E. F.*, Adegunloye D. V.

Chicken feathers pose a significant environmental challenge due to their high resistance to natural degradation. It accumulates in the environment and constitutes serious problems to human health. The study was conducted to degrade chicken feathers by keratinase from selected bacteria isolated from soil samples containing chicken feather waste and the resulting hydrolysate used as a supplement in ...
