RESUMEN
Background: Bacteriophages are a promising biotechnological against bacterial pathogens. Currently, phage research is garnering interest in sub-Saharan countries as bacterial resistance to antibiotics becomes widespread. They are sought in all environments as they offer the possibility of a sustainable alternative to antibiotics. Materials and Methods: Altogether 30 water samples from urban sewage and environmental water were screened for the presence of bacteriophages able to infect Escherichia coli and Enterobacter cloacae. Their genomic diversity was determined by random amplification of polymorphic DNA (RAPD)-PCR fingerprinting. Results: We isolated 35 phages including 9 polyvalent phages that infect simultaneously E. coli and E. cloacae. This study allowed first isolation of E. cloacae-specific phages in Côte d'Ivoire. All phages were distinct based on their RAPD band patterns. Conclusions: Sewage systems of Yopougon and the environmental water of Ebrié lagoon were a rich source of phages. The phage collection could be useful for phage application in Côte d'Ivoire.
RESUMEN
The lytic Escherichia coli siphophage BRET was isolated from a chicken obtained at a local market in Abidjan, Côte d'Ivoire. Its linear genome sequence consists of 59,550 bp (43.4% GC content) and contains 88 predicted genes, including 4 involved in archaeosine biosynthesis. Phage BRET is related (95% nucleotide identity) to Enterobacteria phage JenK1.
RESUMEN
The lytic Escherichia coli phage Ebrios was isolated from a water sample collected in Ebrie Lagoon on the Adiopodoumé River in Abidjan (Republic of Côte d'Ivoire, West Africa). The linear genome of this Podoviridae family member contains 39,752 bp, has a G+C content of 52.9%, is composed of 53 open reading frames, and is related to the Stenotrophomonas maltophilia phage IME15.
