Biopreservative application of bacteriocins obtained from samples Ictalurus punctatus and fermented Zea mays
This study evaluated the preservative ability of protein-like cell free supernatants produced by lactic acid bacteria (LAB) isolates from samples of Ictalurus punctatus (Cat fish) and slurry of fermented Zea mays (Ogi). The LAB strains were separately isolated from understudied samples using De Man, Rogosa and Sharpe (MRS) media at 37°C for 48 h. The isolated strains were characterized with Gram staining, oxidase...

Aflatoxigenic potential of Aspergillus section Flavi isolated from maize seeds, in Burkina Faso
The frequency of occurrence and four principal kinds of aflatoxin concentration in maize seeds grown in Burkina Faso was investigated. Ten (10) samples collected, were analyzed by high performance liquid chromatography (HPLC) with post-column derivatisation after immunoaffinity column cleanup. Eight strains of Aspergillus section Flavi were previously isolated from these samples and cultivated on “Aspergillus...

Detection of Legionella pneumophila as the cause of atypical pneumonia in the water sources of the holy places of Makkah
Legionella pneumophila is an important pathogen and is involved in more than 95% of cases of severe atypical pneumonia. The current study focused on the ablution water in the grand mosque in Makkah as well as water tanks in hotels surrounding the holy mosque. A total of 100 water samples were collected from ablution water in the Haram and the hotels in the central area around the grand mosque and sent to the...

Phenotypic and genotypic characterization of antibiotic resistant gram negative bacteria isolated in Tabuk City, Saudi Arabia
Antimicrobial surveillance and identifying the genetic basis of antimicrobial resistance provide important information to optimize patient care. The present study is an analytical cross sectional study aimed to determine the prevalence of multidrug resistant (MDR), extensively drug resistant (XDR), pan drug resistant (PDR) and extended-spectrum ?-lactamases genes among Gram-negative bacteria isolated in Saudi...

Effect of bacteriocins from lactic acid bacteria obtained from Zea mays-based “Ogi” on foodborne bacteria from contaminated cabbage
The objective of this work was to evaluate the effect of bacteriocins from lactic acid bacteria (LAB) in Zea mays-based Ogi on some foodborne bacteria contaminating cabbage in Abakaliki, Nigeria. Ten (10) samples (5 samples of Z. mays-based Ogi and 5 samples of suspected contaminated cabbage heads) were aseptically collected and analyzed using standard microbiological methods. Five different Lactobacillus isolates (A,...

Prevalence and characterization of extended-spectrum ?-lactamase-producing Escherichia coli and Klebsiella pneumoniae isolated from poultry in Ouagadougou, Burkina Faso
This study aimed to determine the prevalence of extended spectrum beta-lactamase producing (ESBL) and multidrug resistant Escherichia coli and Klebsiella pneumoniae. A cross-sectional study was conducted in Ouagadougou in two poultry farms and two slaughterhouses. 375 cloacal swabs and 46 environment samples were collected and members of Enterobacteriaceae were isolated on EMB agar containing 4 µg/L of cefotaxime....

Heavy metals and microbial contamination of palm oil produced and sold at some markets in Kogi East Area, Kogi State, Nigeria
The physicochemical, microbial and heavy metal contamination of palm oil samples randomly selected from three different markets (Ankpa, Anyigba and Idah Markets) in Kogi State, Nigeria, was investigated. The results revealed the presence of moisture (0.5, 0.4, 0.4%); impurity (0.4, 0.4, 0.3%) and free fatty acid (13, 12.8, 12.3%) for Ankpa, Anyigba and Idah Markets respectively. The microbial contaminants isolated were...
