| [serological study of rickettsia infections in niamey, niger]. | rickettsioses is a possible alternative to presumptive diagnosis of malaria. a serologic study was carried out in 1994 to determine the prevalence of rickettsioses in children under 5 years of age from three different areas of niamey, niger. indirect immunofluorescent assays using the micromethod were performed with antigens for rickettsia conori, rickettsia mooseri, and coxiella burneti. results were read from a positive threshold of 1/160 up to 1/640. out of a randomized population of 177 chil ... | 1997 | 9304008 |
| [study of two goitrous endemic areas in niger: belley-koira and tiguey-tallawal]. | the present work reports the clinical and laboratory findings in two endemic areas in niger: tiguey-tallawal and belley-koira. the goitrous subjects (n = 293), mainly children and adolescents, have clinical evidence of euthyroidism but with biological criteria of hypothyroidism in 25% of cases as shown by the decrease of the total serum t4 and the increase of serum tsh. iodine deficiency intake evaluated by the determination of urinary iodine in single urine specimens is the permissive and main ... | 1990 | 1966663 |
| bovine tuberculosis prevalence survey on cattle in the rural livestock system of torodi (niger). | bovine tuberculosis (btb) is a widespread zoonosis in developing countries but has received little attention in sub-saharan africa, especially in niger. recent investigations confirmed the high incidence of the disease in cattle slaughtered in an abattoir in niamey. the fact that most of the animals in which m. bovis has been identified were from the rural area of torodi implied the existence of a probable source of btb in this region. this study aimed to determine the prevalence of btb infectio ... | 2011 | 21961039 |
| antibodies to hemorrhagic fever viruses in domestic livestock in niger: rift valley fever and crimean-congo hemorrhagic fever. | a repository of domestic animal sera collected in niger between 1984 and 1988 was assayed for antibody against two zoonotic hemorrhagic fever viruses known to be present in the west african sahel. a total of 2,540 serum samples from 2,324 cattle, sheep, goats, and camels were tested by an igg-specific enzyme-linked immunosorbent assay (elisa) and the 80% plaque reduction neutralization test (prnt80) for rift valley fever (rvf) virus antibody. of the 2,540 sera tested for rvf-specific igg antibod ... | 1995 | 7573699 |
