    Antibiotic sensitivity of some bacteria isolates isolated from scouring calves from some farms in Oyo and Ogun States, Nigeria
    (Faculty of Veterinary Medicine, University of Ibadan, Nigeria, 2018) Olaogun, S. C.; Jeremiah, O. T.; Jubril, A. J.
    Diarrhoea in young pre-weaned calves is one of the most important causes of calf morbidity and mortality. Information on this multi-aetiological condition is scanty in Nigeria. Therefore, we studied the prevalent bacteria and antibacteria susceptibility to various bacterial isolates from faecal samples of suspected cases of calf scours in Oyo and Ogun States of South-western Nigeria. One hundred and twenty calf faecal samples (120) from various breeds of cattle showing clinical manifestation of scours were screened for bacterial agents in two farms in Oyo and five farms in Ogun States. Isolation and identification were done using standard procedures, while antibiotic sensitivity was done using Kirby Bauer's disc diffusion method. Escherichia coli, Salmonella spp. and Campylobacter spp. were identified. Out of all the calves, 19 calves (15.8%) were positive for bacteria agents, E. coli was isolated from 12 calves (10%), Salmonella spp. was isolated in 10 calves (8.3%) and Campylobacter spp. was isolated in 1 calf (0.8%). Antibiotic sensitivity test revealed that the most sensitive antibiotics were Meropenem (91.3%) and Amikacin (82.6%) while the least sensitive was Ampicillin (21.7%). Therefore Meropenem is the most sensitive antibiotic and recorded the highest percentage sensitivity in all the three bacteria pathogens isolated, while Ampicillin appeared to be the least sensitive antibiotic to virtually all the pathogens isolated. Meropenem is therefore recommended as the drug of choice for the management of bacteria calf scours. The isolation of highly pathogenic E.coli 0157 from calf scour cases reaffirmed cattle as a reservoirs host which may enter the food chain and poses a faeco-oral potential public health hazards.

    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.
