potentially zoonotic shiga toxin-producing escherichia coli serogroups in the faeces and meat of food-producing animals in ibadan, nigeria.shiga toxin-producing escherichia coli (stec) are major food-borne pathogens associated with gastroenteritis and sometimes fatal haemolytic uraemic syndrome complication. farm animals are asymptomatic carriers of stec and contaminated meat is an important vehicle for zoonotic transmission from animals to humans. this study investigated the presence, virulence traits and antimicrobial susceptibility of seven potentially human pathogenic stec serogroups (o157, o26, o91, o103, o111, o128 and o145) ...201020643488
rift valley fever in nigeria: infections in domestic animals.between 1986 and 1989, 2,255 sera collected from six domestic animal species in nigeria were tested for antibodies to rift valley fever (rvf) virus. in addition, a longitudinal study was carried out from july 1987 to december 1988, using ten sentinel flocks on four farms at ibadan and ile-ife, to determine the activity of rvf virus (rvfv). all samples were tested for haemagglutination-inhibiting antibodies and positive sera were further screened, using the plaque reduction neutralisation test. o ...19969025143

studies on west african dwarf sheep: incidence of perinatal mortality in nigeria.a study was conducted on the incidence of perinatal lamb mortality with extension up to 30 days of age (pmr 30) in west african dwarf sheep in ibadan, nigeria, over a three year period. an overall pmr 30 of 19.9% was recorded. this consisted of an abortion rate of 3.0%, a still-birth rate of 2.7% and a neonatal lamb mortality rate of 15.6% up to 30 days of age (lmr). abortion rate was significantly higher in pregnancies with multiple foetuses and during the dry sea son (p less than 0.01 and p le ...19911775695
a survey for haemagglutination-inhibiting antibody to west nile virus in human and animal sera in nigeria.a survey for west nile virus (wnv) haemagglutination-inhibition (hi) antibody was carried out in humans and domestic animals. human sera were collected from ibadan, while the animal sera were collected from both ibadan and maiduguri. out of 304 human sera tested, 123 were positive (40%). there was a higher prevalence of hi antibody in adults than children. sex distribution of positive sera showed that 37% of males and 43% of females had wnv hi antibody. there was no significant difference in the ...19902323182

anaplasmosis of small ruminants in nigeria: incidence and parasite identification through blood smear and latex agglutination test (lat).a survey was carried out on the incidence of anaplasmosis in small ruminants at bodija abattoir, ibadan. 100 sheep and 200 goats were examined using and comparing two methods-the giemsa stained blood smear and serodiagnosis by latex agglutination technique. the sheep and goats examined were among those brought from various parts of northern states and some neighbouring countries like chad, benin, niger and burkina faso. 27% of the sheep and 17.5% of goats were positive for anaplasma bodies with ...19863557833
studies on cysticercosis of small ruminants in nigeria.1,132 animals (720 goats and 412 sheep) brought to the ibadan abbatoir within a six month-period were examined during necropsy for the presence of cysticercus tenuicollis. c. tenuicollis was found in 20.97% and 23.30% of goats and sheep respectively. in both species, female animals were more predisposed to infection and it appears that adult animals were more susceptible. there was a low degree of infection during the dry season. the economic and public health importance of this disease are disc ...19836676341
the incidence of echinococcus infection in dogs, sheep and goats slaughtered in ibadan, nigeria.an investigation was conducted to determine the incidence of echinococcus infection among dogs and slaughtered sheep and goats in ibadan municipality. of 102 dogs examined, forty-nine (48%) had echinococcus-like ova. parasite eggs from four (3.9%) of these animals produced echinococcus larvae when cultured while twenty (19.6%) of the faecal samples had proglottides. two hundred and fifteen sheep and goats were examined at four different abattoirs. only 28% had hydatid cysts.19827174236

field and laboratory investigations into the role of the musca species in the transmission of intestinal parasitic cysts and eggs in nigeria.houseflies caught on refuse dumps in six areas of ibadan were dissected and the intestinal parasitic cysts and eggs which were found in their alimentary canal were similar to those found in the examined faeces of the community living in the environment. strongly eggs were also found in the alimentary canal of musca species which had fed on the faeces of an infected sheep. while the houseflies caught in the living quarters the high income group were free of parasites, some of these caught in and ...1977562375
