(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.

In-vitro dissolution and some physical properties of two generics of levamisole blous formulations for large animals.
(Indo American Journal of Pharmaceutical Research (IAJPR) Publications, 2017) Gberindyer, A. F.; Omotosho, O. O.; Olaogun, S. C.
Physical and dissolution properties of solid oral dosage formulations significantly affect therapeutic outcomes following their use in veterinary medicine. Therapeutic failure of most levamisole boluses for the prevention and treatment of helminth infections have been a recurrent complaint from animal health workers and veterinarians in Nigeria. However, there is dearth of information on the quality of oral bolus formulations of levamisole for veterinary use in Nigeria. Consequently, the purpose of this study was to evaluate physical and dissolution properties of two generic products of levamisole boluses commonly used in large animal practice in Nigeria. Two frequently used generics of levamisole oral boluses for large animal practice (A & B) were evaluated for bolus weight uniformity, hardness, friability, disintegration and dissolution as specified in the United States Pharmacopoeia. The results demonstrated that generic B failed weight uniformity and friability tests, whereas generic A failed friability and disintegration tests. All the products passed dissolution profile test as specified. Consequently, the two products can be used interchangeably, however, generic B is recommended for treating acute enteric helminthosis because of its fast disintegration and dissolution rates as compared to generic A.
Occurrence of Skin Abscess and Sensitivity Pattern of Associated Bacterial Organisms in Pigs on Ifelodun Farm Settlement, Ogun State, Nigeria
(Faculty of Veterinary Medicine, Alexandria University, Egypt, 2016) Omotosho, O. O.; Olaogun, S. C.; Odukaye, A. O.
Pigs are relatively prone to abscess formation especially in the skin. This study was designed to assess the occurrence of skin abscess in pigs on the Ifelodun farm settlement in Ogun state, South-West Nigeria and evaluate the antibiotic sensitivity pattern of bacterial organisms isolated from pus samples from the abscesses. A total of 2,909 pigs from 104 randomly selected farms on the Ifelodun farm settlement were physically examined. The anatomic locations of gross swellings on the skin were noted. Diagnosis of skin abscess was arrived at after palpation and aspiration of content. Pus samples from 14 intact abscesses were collected aseptically for isolation and sensitivity using standard cultural and disc diffusion method respectively. Data were analysed using descriptive statistics. 26 (0.89%) of the 2,909 pigs examined across 22 (21.2%) farms out of 104 farms surveyed were affected. The anatomic distribution of the abscesses includes 43.3%, 6.67%, 16.67% and 33.33% on the neck, forelimbs, trunk, and hind limbs respectively. None was observed on the head. 10 bacterial species were isolated from the 14 tested isolates with Arcanobacterium pyogenes (57.1%), Staphylococcus aureus (42.8%) and Escherichia coli (35.7%) being most frequently isolated. Antibiotic sensitivity profile varied with more isolates being sensitive to Erythromycin, Tetracycline, Gentamicin, and Chloraphenicol for gram positive bacterial species and Ceftazidine, Cefuroxime, Gentamicin and Augmentin for gram negative species. Swine skin abscess affects various body regions in pigs on Ifelodun pig farm settlement. The neck and hind limbs were mostly affected likely due to poor injection practices. Based on availability of veterinary preparation readily available in the Nigerian market, Gentamicin, Tetracycline and Erythromycin remain viable options for post-surgical management of the abscesses while Chloramphenicol should be avoided due to its deleterious effect on humans. Antibiotic sensitivity is recommended in cases of recurring skin abscesses in a pig or herd.
Patterns, trends and correlates of ten major reported crimes in Ondo State, Nigeria
(Connel Publications, Ibadan, 2019) Taiwo, O. J.; Olumoyegun, J. M.; Omotosho, O. O.
We analysed the trend, patterns, and correlates of ten major crimes among Local Government Areas (LGAs) in Ondo State. The number of reported crimes from 2007 to 2016 were used to assess the trend in crimes, while the reported number of crimes in 2007 and 2010 from the 18 LGAs were used for the analysis of the spatiotemporal distribution and pattern of crimes. The reported number of murders, rape and indecent assault, assault, pretence/cheating, breach of the public peace, kidnapping and forgery increased while burglary and armed robbery declined. Akure South, Ondo West, Akure North, and Ilaje LGAs had the highest reported crimes. Nearly all the crimes exhibited a random distributional pattern in 2007 and 2010 except assault and kidnapping. There was a significant difference between the number of reported crime in urban and rural LGAs (F( 1,358)=4.148) while the number of hotels and population density was highly correlated with some crimes. Availability of relatively long-time data provides opportunity to understand the spatiotemporal trend, pattern and correlates of major crimes in Ondo State, Nigeria.
