Outbreak investigations and molecular characterization of foot-and-mouth disease viruses circulating in south-west Niger Instituut voor Tropische Geneeskunde

B. Souley Kouato, F. M. Elliot, D. P. King, J. Hyera, N. J. Knowles, A. B. Ludi, V. Mioulet, G. Matlho, K De Clercq, Eric Thys, et al.

In Niger, the epidemiological situation regarding foot-and-mouth disease is unclear as many outbreaks are unreported. This study aimed (i) to identify Foot-and-mouth disease virus (FMDV) strains currently circulating in cattle herds, and (ii) to identify risk factors associated with Foot-and-mouth disease (FMD)-seropositive animals in clinical outbreaks. Epithelial tissues (n=25) and sera (n = 227) were collected from cattle in eight ...

Spatio-temporal patterns of foot-and-mouth disease transmission in cattle between 2007 and 2015 and quantitative assessment of the economic impact of the disease in Niger Instituut voor Tropische Geneeskunde

B. Souley Kouato, Eric Thys, V. Renault, E. Abatih, H. Marichatou, S. Issa, C Saegerman

Foot-and-mouth disease (FMD) is endemic in Niger, with outbreaks occurring every year. Recently, there was an increasing interest from veterinary authorities to implement preventive and control measures against FMD. However, for an efficient control, improving the current knowledge on the disease dynamics and factors related to FMD occurrence is a prerequisite. The objective of this study was therefore to obtain insights into the incidence ...

Cross-sectional survey of brucellosis and associated risk factors in the livestock-wildlife interface area of Nechisar National Park, Ethiopia Instituut voor Tropische Geneeskunde

Hassen Chaka, Gezahegn Aboset, Abebe Garoma, Balako Gumi, Eric Thys

A cross-sectional survey was carried out to investigate the seroprevalence of ovine and bovine brucellosis in the livestock-wildlife interface area of Nechisar National Park, Ethiopia. Furthermore, producer's knowledge about brucellosis and its zoonotic potential was assessed using a structured questionnaire. A total of 268 cattle and 246 goat sera were collected from 50 herds and 46 flocks and subjected to Rose Bengal test (RBT) and ...

PCR and microsatellite analysis of diminazene aceturate resistance of bovine trypanosomes correlated to knowledge, attitude and practice of livestock keepers in South-Western Ethiopia Instituut voor Tropische Geneeskunde Universiteit Gent

Y. Moti, Reginald De Deken, Eric Thys, Jan Van Den Abbeele, Luc Duchateau, Vincent Delespaux

African Animal Trypanosomosis is threatening the agricultural production and cattle breeding more severely than any other livestock disease in the continent, even more since the advent of drug resistance. A longitudinal study was conducted from November 2012 to May 2013 in the Ghibe valley to evaluate diminazene aceturate (DA) resistance and assess livestock owner's perception of trypanocidal drug use. Four Peasant Associations (PAs) were ...

Bayesian estimation of the true prevalence, sensitivity and specificity of the Rose Bengal and indirect ELISA tests in the diagnosis of bovine brucellosis Instituut voor Tropische Geneeskunde

Moussa Sanogo, Eric Thys, Y.L. Achi, D. Fretin, P. Michel, E.N. Abatih, D. Berkvens, Claude Saegerman
Serology is the most convenient method for detecting brucellosis but the efficient use of such tests in disease control requires evaluation of diagnostic performance and discriminative ability. The objective of this study was to assess the performance of the Rose Bengal test (RBT) and an indirect ELISA (iELISA) in diagnosing brucellosis in 995 serum samples collected from cattle in the Ivory Coast between 2005 and 2009. A Bayesian approach was ...

Intersectoral collaboration between the medical and veterinary professions in low-resource societies: the role of research and training institutions Instituut voor Tropische Geneeskunde

T. Marcotty, Eric Thys, P. Conrad, J. Godfroid, P. Craig, J. Zinsstag, Filip Meheus, Abdou Razac Boukary, M.A. Bade, H. Sahibi, et al.
BACKGROUND: Neglected zoonoses continue to significantly affect human health in low-resource countries. A symposium was organised in Antwerp, Belgium, on 5 November 2010 to evaluate how intersectoral collaboration among educational and research institutions could improve the situation.
RESULTS: Brucellosis and echinococcosis were presented as models for intersectoral collaboration. Low-resource societies face evident knowledge gaps on ...

Economic burden of bovine trypanosomosis in three villages of Metekel zone, Northwest Ethiopia Instituut voor Tropische Geneeskunde

D Tesfaye, Niko Speybroeck, Reginald De Deken, Eric Thys
The study was carried out to assess the economic burden of trypanosomosis in three villages of the Metekel zone in 2009. The disease was found to cause substantial economic losses through cattle mortality, drug purchase, and draft power loss of infected oxen. The farmers in the area were spending a significantly (p < 0.05) higher amount of money for the treatment of trypanosomosis than all other diseases combined. The overall mortality rate ...

Risk factors associated with brucellosis seropositivity among cattle in the central savannah-forest area of Ivory Coast Instituut voor Tropische Geneeskunde

Moussa Sanogo, E.N. Abatih, Eric Thys, D. Fretin, D. Berkvens, C Saegerman
Serological results obtained from 907 serum samples collected from unvaccinated cattle of at least 6 months of age in the savannah-forest region of Ivory Coast were used to investigate risk factors associated with bovine brucellosis seropositivity. Serum samples were tested using the Rose Bengal test (RBT) and indirect enzyme linked immunosorbent assay (iELISA). Using a parallel interpretation, RBT and iELISA results showed that 10.3% (95% ...
