Fecal Antibiotic Resistome of Pigs from a Small-Scale Piggery in Ibadan, South-West Nigeria
(ResearchersLinks (Nexus Academic Publishers, NAP), 2021-05-28) Olayinka, O. A.; Faleye, T. O. C.; Omotosho, O. O.; Odukaye, O. A.; Oluremi, B.; Ibitoye, I. H.; Ope-Ewe, O. O.; George, U. E.; Arowolo, O. A; Ifeorah, I. M.; Omoruyi, E. C.; Donbraye, E; Adeniji, O. P.; Adewumi, O. M.; Adeniji, J. A.
This study was designed to sample the fecal Resistome of Pigs from a small-scale Piggery in Ibadan, South-West Nigeria. Three fecal pellets were randomly picked from the floor of unit pens containing a minimum of three pigs per unit in selected piggery in Ibadan, Nigeria. The samples were pooled and resuspended in phosphate buffered saline. The suspension was then subjected to nucleic acid extraction, Cdna synthesis and Illumina sequencing. Antibiotic Resistance Genes (ARGs) in the raw reads were determined and assembled using the Kmer Resistance tool v2.2. From the 2,974,257 reads generated, 21 ARGs with statistically significant reads were identified. Almost all targeted broad-spectrum antibiotics with over 50% targeting Tetracyclines. Five (ant(6)-Ia_3, tet(40)_1, tet(Q)_1, tet(W)_5 and tet(O/W)_4) of the ARGs were predicted to be plasmid-borne. Our findings show that the Swine industry in the region might be both a mixing pot and reservoir of ARGs. It is therefore crucial that effort is made to educate the stakeholders on the importance of good antibiotics stewardship.

Non-polio enterovirus species c infection in AFP cases and its implication for the emergence of recombinant circulating vaccine- derived polioviruses
(ResearchersLinks Ltd., 2020) Adewumi, O. M.; Faleye, T. O. C.; Ope-Ewe, O. O.; Ibitoye, I. H.; Arowosaye, A. O.; Adelowo, O. D.; Adeniji, J. A.
Using 40 faecal samples from acute flaccid paralysis (AFP) cases collected in 2019, we examined how coupling Enterovirus (EV) isolation in RD and MCF-7 cell culture with direct detection from clinical sample might impact our ability to detect non-polio EV Species C (NPESC) members in stool samples. In all, 20% (8/40) of all the samples screened had NPESCs and 50% (8/16) of the EVs detected were NPESCs. However, the RD cell line missed all NPESCs. Hence, RD cell line alone should not be used for EV isolation if the desire is to also isolate NPESC.
