Aflatoxin Contamination in Spices Sold in Ilorin, North-Central, Nigeria

Ahmed El-Imam*, Amina, M, Oguntimehin, S. A, Sanni, A.

Spices are commonly contaminated with aflatoxins, a group of potent mycotoxins produced by moulds. This study investigated the incidence of aflatoxigenic fungi and aflatoxin contents in spices commonly used in Ilorin, North Central Nigeria. Sixty samples of thirteen different spices were purchased from three markets. Fungal isolates were identified using phenotypic characteristics. Aflatoxin conta...

Antibiogram of Clinical Isolates of Escherichia coli and Klebsiella species Producing Extended Spectrum Beta Lactamase (ESBL)

Ovia, K. N*, Ibiam, U, Okoh, N, Okafor, C. O, Eronmosele, B. O, Okoroafor, I, Ejikeugwu, C

The public health threat posed by bacteria producing extended spectrum beta lactamase (ESBL) is increasingly contributing to the global challenge of antimicrobial resistance (AMR) which is slowly ushering in a post antibiotic era – where no antibiotic is likely to work. AMR is a global health threat that warrant urgent steps to mitigate its growing ugly trend. This study investigated the susceptib...

Incidence of Bacteria Associated with Post Harvest Rot of Colocasia esculenta LIN (Cocoyam) Tubers Sold in Different Markets in Bukuru, Jos South Local Government Area, Nigeria

Danahap, L. S.*, Christopher, I, Okechalu, O. B.

The bacteria species associated with post-harvest rot of Colocasia esculenta Lin (Cocoyam) tubers sold in Bukuru market of Plateau State were investigated. Fifty (50) Samples of C. esculenta were obtained randomly from 3 different Markets within Bukuru and brought for analysis. The tubers were surface disinfect with Sodium Hypo chloride (NaOCl) for 5 minutes. A portion of the rotten sample and the...
