Anthrax toxins-producing Bacillus spp. isolated from handwashing stations during COVID-19 pandemic in Lagos, Nigeria.

Introduction: The virulence binding factor, protective antigen (pag) and poly-D-γ-glutamate capsular (cap) genes, peculiar to Bacillus anthracis are located in the pXO1 and pXO2 plasmids which are transferable horizontally to related species called "cereus group". The cereus group are usually isolated from the environmental/food samples and have been implicated in debilitating human and animal anthrax-like diseases. This study was designed to investigate the presence of the anthrax virulence genes in different Bacillus spp.

Screening, isolation and biotechnological potentials of foodborne strains MT903311 and MT903312.

Vitamins are an essential food source with excellent roles in the cellular metabolism and other essential nutrients required in food intake but cannot be synthesized by humans. There have been reports of some lactic acid bacteria (LAB) abilities with probiotic activities to produce food-grade vitamins. Our study aimed to investigate lactic acid bacteria (LAB) possessing antimicrobial activities and extracellular production of folate from different Nigerian fermented foods.

Antibiotic resistance and plasmid analysis of Enterobacteriaceae isolated from retail meat in Lagos Nigeria.

Background: The presence of antibiotic resistant microorganisms in food is of great concern globally. This research was carried out to detect and characterize plasmid carriage and profiles among members of Enterobacteriaceae from different meat types in Nigeria.

Method: From a total of 80 meat samples comprising of mutton,pork, beef and chicken, organisms belonging to the family Enterobacteriaceae wereisolated by standard procedures and identified by API 20E system.

Incidence of Multidrug-Resistant Escherichia coli Harbouring blaTEM and tetA Genes Isolated from Seafoods in Lagos Nigeria.

The presence of multidrug-resistant Escherichia coli of fecal origin in seafood is a serious concern. Seafood containing MDR E. coli can serve as a medium for the transfer of resistant bacteria to consumers.

Draft Genome Sequence of sp. Strain MC-1LL, a Bacterial Strain with Antimicrobial Properties, Isolated from Marine Sediments in Nigeria.

Here, we report a 4.3-Mb draft genome sequence of a potential new species, which clarified its taxonomic position and gave insight into the complete secondary metabolite production capacity of the strain.

Antibiotic susceptibility pattern and analysis of plasmid profiles of Pseudomonas aeruginosa from human, animal and plant sources.

Multidrug resistant organisms (MDROs) constitute a major public health threat globally. Clinical isolates of Pseudomonas aeruginosa remains one of the most studied MDROs however there is paucity of information regarding the susceptibility of its animal and plants isolates to antipseudomonas drug in Nigeria. From a total of 252 samples consisting of plants, animals and clinical samples, 54, 24 and 22 P.

Occurrence of aminoglycoside-modifying enzymes genes (aac(6')-I and ant(2″)-I) in clinical isolates of Pseudomonas aeruginosa from Southwest Nigeria.

Background: Enzymatic modification of aminoglycosides is the primary mechanism of resistance by Pseudomonas aeruginosa.

Obejectives: We investigated the occurrence and mechanism of aminoglycosides resistance in P. aeruginosa isolates from hospitals in SouthWest Nigeria.

Identification and prevalence of tetracycline resistance in enterococci isolated from poultry in Ilishan, Ogun State, Nigeria.

Background: Tetracycline is one of the most frequently used antibiotics in Nigeria both for human and animal infections because of its cheapness and ready availability. The use of tetracycline in animal husbandry could lead to horizontal transfer of tet genes from poultry to human through the gut microbiota, especially enterococci. Therefore, this study is designed to identify different enterococcal species from poultry feces in selected farms in Ilishan, Ogun State, Nigeria, determine the prevalence of tetracycline resistance/genes and presence of IS256 in enterococcal strains.

First Detection of OXA-10 Extended-Spectrum Beta-Lactamases and the Occurrence of mexR and nfxB in Clinical Isolates of Pseudomonas aeruginosa from Nigeria.

Background: The characterization of β-lactamase production in Pseudomonasaeruginosa is rarely reported in Nigeria. The objective of this study was to investigate the occurrence and characterize the different β-lactamases as well as mechanisms of fluoroquinolones resistance among P. aeruginosa isolated from various clinical sources from Nigeria.

Analysis of integrons and associated gene cassettes in clinical isolates of multidrug resistant Pseudomonas aeruginosa from Southwest Nigeria.

Background: Multidrug resistant Pseudomonas aeruginosa harbours integrons and other mobile genetic elements such as plasmids and transposons, which easily disseminate antibiotic resistance genes among clinical strains of P. aeruginosa.

Methodology: Plasmid extraction of 54 clinical isolates of P.
