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.
Calf Diarrhea: Epidemiological Prevalence and Bacterial Load in Oyo and Ogun States, Nigeria
(Alexandria Journal of Veterinary Sciences, 2016) Olaogun, S. C.; Jeremiah, O. T.; Jubril, A. J.; Adewuyi, O. O.
Diarrhea in calves is one of the most important causes of calf morbidity, mortality and economic losses. The prevalence of diarrhea in calves was studied in 12 farms in Oyo and Ogun states in South Western Nigeria. A total of 825 calves up to 6-months old were sampled over a period of 12 months with 120 (14.5%) of the calves showing signs of diarrhea. Faecal samples of diarrheic calves (n=120) were collected, and screened for bacterial pathogens using standard laboratory procedures. In Oyo and Ogun States, highest prevalence rates of calves with diarrhea were noticed in two farms of Oyo State 50% (25 out of 50 calves) and Ogun State 23% (12 out of 52 calves) were recorded respectively. Only 19 (15.8%) of the 120 calves had bacterial pathogens; Of the calves (n=19) where bacteria were isolated Escherichia coli was isolated from 12 calves (63.2%), Salmonella species was isolated from 10 calves (52.6%) and Campylobacter species was isolated from 1 calf (5.3%). The lowest levels of bacterial detection were seen in diarrheic samples from White Fulani calves (8.9%) with the highest levels seen in samples from Jersey calves (50%). Calves of 0-2 months had positivity bacterial cause of diarrhea of 18.4%, calves between 3 and 4 months had positivity of 8.8% and calves of 5-6 months had positivity of 20%. Bull calves had 17.0% positivity while heifers had 14.8% positivity among diarrheic calves. Calves having severe diarrhea had highest percentage positivity (26.1%) of bacterial isolates while calves with moderate diarrhea had the least percentage positivity (13.6%). Calves reared in semi-intensive system of management were the most susceptible (18.0%) while those reared under extensive system were least susceptible (13.6%) to bacterial scours. Therefore, Escherichia coli, Salmonella and Campylobacter organisms were most prevalent in calf scours. Age, breeds, sex, severity of diarrhea and system of management are predisposing factors of calf diarrhea.
Internal and external morphometry of Thomas's rope squirrel (Funisciurusanerythrus) and Gambian Sun Squirrel (Heliosciurus Gambianus) In Ibadan, Nigeria
(University of Nigeria, Nsukka, 2020) Coker, O. M.; Jubril, A. J.; Isong, O. M.; Omonona, A. O.
Currently, no information exists regarding internal and external morphometrics and their correlations in Funisciurus anerythrus and Heliosciurus gambianus. Therefore, this study examined the relationships among the internal and external morphometrics of the two species in University of Ibadan, Ibadan, Nigeria. Samples of adult F. anerythrus (n = 20) and H. gambianus (n = 13) were trapped from the wild at various locations within the campus. Live weights (LW), external measurements and weights of internal organs were taken. Comparisons within and between both species were carried out using T-tests and Pearson's correlation coefficient at p<0.05. H. gambianus was significantly bigger than F. anerythrus for all the measured parameters, except in ear and snout lengths. Male F. anerythrus was significantly bigger than female in LW, body length (BL) and shoulder to tail length (STL) while, female H. gambianus was significantly bigger than male in trunk circumference (TC). In male F. anerythrus, BL significantly correlates with STL (r = 0.85). In female F. anerythrus, LW correlates significantly with hind limb length (r = 0.62) and both kidneys. In male H. gambianus, LW correlates significantly with head length (r = 0.79), tail length (r = 0.81), BL (r = 0.97), STL (r = 0.87), and the weights of lungs and kidneys. In female H. gambianus, LW correlates significantly with TC (r = 0.99) and right lung weight (r = 0.92). Both species show some levels of sexual dimorphism and substantial positive correlations among the external and internal measurements.
Wildlife market and predisposition to zoonotic disease in Ibadan, South-Western Nigeria.
(Society for Public Health Professionals of Nigeria (SPHPN), 2020) Omonona, A. O.; Jubril, A. J.; Salami, K. K.; Coker, O. M.; Olumide, A. O.; Omobowale, M. O.; Azeez, A.; Adetuga, A. T.; Ayegboyin, M.; Oyetunde, O. I.
Background: Recent cases of global epidemics rooted in zoonotic diseases' transmission engendered the exploration of wildlife beliefs and practices toward disease transmission among vendors in wildlife markets. Objectives: The study explored the wildlife market practices in order to understand how the markets, attitudes and behaviours of traders can potentially influence the transmission of zoonotic diseases in Nigeria. Methods: The study employed a qualitative research method, involving non-participant observation and interviews of 22 consented vendors from five wildlife markers in Ibadan, Nigeria. Results: Wildlife vendors were neither grounded about animal-human transmission of diseases, nor hardly suspected their stock as a route or gateway for zoonoses' transmission to humans. They also embraced metaphysical explanation of disease aetiology among them. Conclusion: Holistic and culturally-designed sensitisation about zoonoses targeting the wildlife vendors could facilitate the adoption of healthy practices when handling wildlife among them.
