Item The comparative effect of onchocerciasis on the people of the northern and southern parts of Nigeria(IDOSI Publications, 2014) Anong, C.I.N.; Adediran, O.A.; Akinboade, O.A.Researchers have variously submitted that Simulium damnosum, the arthropod vector carrying the onchocerciasis parasite, breeds during the rainy season in the south western part of Nigeria. Since there is a difference in the climatic condition found in the northern part of Nigeria, we need to specially do a comparative study of situations in the North, as related to the disease, in terms of its causes and effects. This study investigated the differences in the North-South prevalence of onchocerciasis and the different types of the disease found in the North versus the South of Nigeria. The comparative strength (quality) of its impact and the spread of its impact. Local government records were accessed and a survey for presence of microfilariae in individuals carried out in Kaduna and Oyo states. Onchocerciasis in the north is more impactful health-wise and economically on the Northern population with higher frequency of occurrence of river blindness and a higher overall prevalence as well as in the productive age groupsItem Seroprevalence of trichinellosis in pigs slaughtered in Bodija abbattoir Oyo State Nigeria(World Journal of Life Science and Medical Research, 2012-12) Adediran, O.; Uwalaka, E. C.This survey was carried out to determine the prevalence of trichinellosis in Bodija municipal abattoir of Oyo state, Nigeria. Sera samples were collected from pigs slaughtered on the slabs from July to November, 2010 and taken to the laboratory in the department of Veterinary Microbiology and Parasitology, University of Ibadan for analysis. The samples were processed for Trichinella antibodies by ELISA using excretory-secretory (E/S) antigen.246 samples were collected and a prevalence of 15.04% was recorded. Adult pigs had a higher prevalence (35.55%) than the young (8.40, 14.29) and prevalence in male pigs was slightly higher (19.80%) than the females (11.72%) though this prevalence is not statistically significantItem Seasonal limnological variation and nutrient load of the river system in Ibadan Metropolis, Nigeria(EuroJournal publishing inc., 2008) Adedokun, O. A.; Adeyemo, O. K.; Adeleye, E.; Yusuf, R. K.Ibadan is a highly populated city, characterized by environmental problems arising from improper disposal of solid and liquid wastes, poor wastes collection and handling. We therefore investigated the seasonal limnology and nutrient load of the river system in Ibadan metropolis, Nigeria during the dry season (October 2003-March 2004) and rainy season (August-September 2004). The results revealed that colour, Total suspended solid (TSS), total solids (TS) and total nitrogen were generally higher during the dry season. This suggests that the run-offs have only a diluting effect on these parameters. All the other physical parameters (pH, BOD, DO, COD, TDS, Total hardness) and Nutrient load based parameters (phosphate, sulphate, nitrate and nitrite) were generally higher during the rainy season. Also, in most of the sample points, BOD, TDS, TSS, colour and phosphate levels were relatively higher than the WHO standards for surface water during the two seasons. The poor water quality and nutrient loading observed in the study area has severe consequences on the in-dwelling aquatic flora and fauna. Proper treatment of effluent from industrial processes to acceptable levels, discouraging stagnation of domestic waste and sewage, availability of sewage treatment plants is necessary to curtail the health risk associated with the present level of pollution observed during this study.Item Intenstinal helminth and protozoan parasites of pigs reared under intensive management system in Ibadan, Nigeria(Tropical Veterinarian, 2001) Adejinmi, J. O.; Adedokun, O.A; Ayoade, G. O.; Obadua, A. A.Two hundred and seventy two pigs of different age groups reared in an intensive management system in 10 different locations in Ibadan were screened for intestinal helminth and protozoan parasites. The following incidences were recorded. Ascaris suum, 25.4% Oesophagostomuir. dentatus 13.6%, TricJiiiris suis, 10.7%; Strongylodes ransomi, 7.0%; Eimeria debliecki, 31.3%, Eimeria suis, 2.2% and Balantidium coli. 0.74%. Mixed infections with these parasites were common. No helminth egg was detected in all the piglets screened. The incidence of helminth parasites increased with age. So also was the worm burden. To prevent widespread infection with these parasites strict adherence to good management and hygiene in piggery pens is recommended
