Item Serological survey of brucellosis in livestock animals and workers in Ibadan, Nigeria(2006-09) Cadmus, S. I. B.; Ijagbone, I. F.; Oputa, H. E.; Adesokan, H. K.; Stack, J. A.A serological survey of brucellosis in livestock animals and workers was conducted in Ibadan, Southwestern Nigeria between May and August 2004. A total of 1,210 cattle, 54 sheep, 496 goats, 200 pigs and 21 humans (i.e. butchers and herdsmen) were screened using the Rose Bengal test (RBT).From the results, prevalence in trade cattle was 5.82% while 0.86% was recorded in goats. None of the sheep and pigs was positive to the test. Out of the 11 samples taken from butchers, seven were positive and none of the ten herdsmen were sero-positive. This gives an infection rate of 63.3% in the butchers; and a combined infection rate of 31.82% in humans. This shows that brucellosis is still a major zoonosis in Nigeria; other public health implications are discussedItem Clinic and laboratory manual: veterinary public health-preventive medicine-wildlife and fish diseases(2008) Adeyemi, I.

O.; Oluwayelu, D.O.; Ijagbone, I. F.; Ayoade, G. O.; Agbede, S. A.The mortality losses of pigs of various age groups affected by the 2001 African swine fever outbreak in Ibadan Nigeria were analyzed and evaluated. Thirty one thousand nine hundred and sixteen (31,916) pigs on three hundred and six (306) farms reported by the Pig Farmers Association of Nigeria and the State Ministry of Agriculture and Natural Resources were involved. Gross mortality was ninety one percent (91%), while age group mortality ranged from 75.9% (growers), 83.1% (weaners), 91.2% (finishers) and 99.8% (piglets); to 100.0% in gilts, sow and boars. Losses were estimated to worth nine hundred and forty one thousand, four hundred and ninety one dollars, sixty seven cents (US $941,491.67). Highest financial loss was from sows (29.5% of total loss), followed by gilts (16.6%), finishers (15.2%), weaners (10.7%), boars (10.6%), growers (10.6%) and piglets (8.2%). Average mortality loss per farm of $3076.77 was of great financial and socioeconomic consequences for a developing country like Nigeria with a low Gross Domestic Product figures. In conclusion, the need to immediately revisit and take recommended actions on the 1998 Report of the FAO Consultancy Mission to Nigeria on Control and Eradication of an Outbreak of African swine fever in Western Nigeria is stressedItem Pattern of spread of African swine fever in south-western Nigeria, 1997-2005(2007) Olugasa, B. O.; Ijagbone, I. F.Geographic coordinates of selected pig farms with confirmed African swine fever (ASF) outbreaks in Ekiti, Lagos, Ogun, Ondo and Oyo States were used to create spatial models of pig farms and ASF outbreaks in southwestern Nigeria between 1997 and 2005. The probability of ASF virus-free pigs remaining in a non-infected state when located at various distances from ASF virus infected pigs was estimated. Movement of infected stock was the most important means of spreading the virus. The estimated mean duration of clinical signs prior to death was 3.4 ± 1.1 days (mean ± standard deviation); the mean convalescent period was 16.3 ± 2.3 days and the mean period of survival after full recovery was 1 084 ± 145.1 days. The continuous presence of recovered pigs in the population enables virus spread through trade and breeding. There is an urgent need for the implementation of an ASF eradication programme in Nigeria.Item An outbreak of animal trypanosomosis in a fulani herd at Idofian in Kwara State Nigeria(2005) Ijagbone, I. F.; Esuruoso, G. O.; Adeyemi, I. G; Olugasa, B. O.An epizootiological investigation was conducted to establish the cause of an outbreak of a disease which reportedly resulted in fifty cases of abortions and thirty deaths out of a population of 1,200-cattle within one month after its onset. The incident occurred in a Fulani.farm settlement located on the outskirt of Idofian via-Ilorin, Kwara State, Nigeria. Using parasitological methods, 9 out of the 34 animals sampled from the herd; were positive for trypanosoniosis, indicating 26.47% prevalence of the disease in the farm; Trypanosoma vivax was detected in seven of the samples while T. congolense was present in two. This finding coupled with other epizootiological parameters examined established trypanosoniosis outbreak in the herd which might have resulted in the reported cases of abortion and death among the cattle. The finding underscores how the disease can still be a major impediment to the growth of cattle enterprise in some parts of Nigeria.Item Introductory epizootiology(VetAcademic Resource Publishers and Consultants, 2005) Esuruoso, G.
