In January 2021, Senegal reported the emergence of highly pathogenic avian influenza virus A(H5N1), which was detected on a poultry farm in Thies, Senegal, and in great white pelicans in the Djoudj National Bird Sanctuary. We report evidence of new transcontinental spread of H5N1 from Europe toward Africa.

Mycoplasma mycoides subsp. mycoides (Mmm) is the aetiological agent of contagious bovine pleuropneumonia (CBPP). The aim of the present study was to identify the profiles of the Mmm strains isolated in Niger using the ‘Multilocus Sequence Analysis’ (MLSA) typing technique based on polymorphism analysis of housekeeping and non‐coding genes. The inve...

Since November 2018, several countries in West and Central Africa have reported mortalities in donkeys and horses. Specifically, more than 66,000 horses and donkeys have succumbed to disease in Burkina Faso, Chad, Cameroon, The Gambia, Ghana, Mali, Niger, Nigeria and Senegal. Strangles caused by Streptococcus equi subsp equi, African Horse Sickness...

Introduction: Escherichia coli is a commensal bacterium of the digestive flora of the man responsible for urinary tract infections. The objective of our work is to determine the resistance profiles of broad-spectrum betalactamase-producing Escherichia coli isolated from the Fann hospital, as well as the beta-lactam resistance genes and the quinolon...

Contagious bovine pleuropneumonia (CBPP) is a highly contagious disease of cattle caused by Mycoplasma mycoides subsp. mycoides Biotype Small Colony (MmmSC). The disease currently occurs in most of sub-Saharan Africa and where it is endemic and a major constraint for improving pastoral productivity. Following the persistence of this scourge, and in...

Wastewater of human and animal may contain Shiga toxin-producing (STEC) and enteropathogenic (EPEC) Escherichia coli. We evaluated the prevalence of such strains in a wastewater treatment plant (WWTP) receiving both city and slaughterhouse wastewater. PCR screenings were performed on 12,248 E. coli isolates. The prevalence of STEC in city wastewate...

In recent years very virulent (VV) IBDV strains and classical (CV) IBDV strains re-emerged and caused devastating outbreaks in different parts of the world. In this study, genetic evolution of fifteen IBDVs collected in Senegal in was characterized to gain information for a better control of IBD. Following RT-PCR, nucleotide sequence of the VP2 hyp...

Bacillus anthracis is the causative agent of anthrax, and it is classified as " category A " biological weapon. There were six available complete genomes (A0248, Ames, Ames Ancestor, CDC684, H0491 and Sterne). Here, one Gambian and two Senegalese strains (Gmb1, Sen2Col2 and Sen3) were added. In this work, the pan-genome of B. anthracis was studied...

The authors mentioned the epizootic infection for Contagious Bovine Pleuro Pneumoniae (CBPP) caused by Mycoplasma mycoides subsp. mycoides biotype Small Colony (MmmSC) which has affected Ndama bovine in Niamina Dankunku a locality based in Abuko city in the eastern part of the Gambia during the rainy season in 2012. After the cessation of vaccinati...

Les auteurs décrivent un foyer d’infection épizootique de péripneumonie contagieuse bovine (PPCB) causée par Mycoplasma mycoides subsp. mycoides biotype petites colonies (MmmSC) qui a affecté des bovins de race Ndama à Lounthy, un village situé dans le Parc national du Niokolo-Koba dans la Réserve nationale communautaire du Boundou, du département...

The authors have described an epizootic infection of contagious bovine pleuropneumonia (CBPP), caused by Mycoplasma mycoides subsp. mycoides biotype Small Colony (MmmSC), that has affected Ndama bovine in Lounthy village, a locality based in Bala city in the Eastern part of Senegal, during the post-rainy season in November 2012. After the cessation...

We compared the prevalence of pathogenic and extended-spectrum beta-lactamase (ESBL) - producing Escherichia coli in effluents of a municipal wastewater treatment plant (WWTP) receiving wastewater from a slaughterhouse. A total of 1248 isolates were screened for the presence of virulence genes associated with enterohemorrhagic E. coli (EHEC) (stx1,...
