The worldwide prevalence of the neglected tropical diseases (NTD) shows the diseases are affecting more than 1 billion. The burden of the Neglected tropical diseases cost to developing, the burden of the diseases cost to developing economies billions of dollars every year. The genomic research in the last decades providing a full sequence (some currently in the sequencing pipeline) of genomes of many of the organisms including those which are responsible of neglected tropical diseases, may help in the management of such diseases. With the human genome being sequenced, the understanding of the genomic interaction between human and NTD pathogen enable scientists to develop new strategies to prevent and treat these devastating diseases. In this context of genomic era, African scientists may interestingly play an insider role in order to be part of the history of the elimination of these diseases. However, a critical mass of African scientists in genomic area constitutes the first step toward this long way in struggle against NTD. Although the challenge is enormous, it is very important to recognize that some African countries and institutions are fully committed to develop and strengthen African leadership in genomic area, while some are conspicuously absent from this debate. Joining African competences and leadership through collaborative activities and moving forward remains the next challenge to really impact the control and elimination of the NTD.

This study aimed to determine the resistance of diarrheagenic Escherichia coli (DEC) strains to β-lactams antibiotics and to perform the molecular characterization of extended-spectrum β-lactamases (ESBLs) and integrons genes. It was carried out from August 2013 to October 2015 and involved 31 DEC strains isolated from diarrheal stools samples collected from children less than 5 years. The identification and characterization of DEC strains were done through the standard biochemical tests that were confirmed using API 20E and polymerase chain reaction (PCR). The antibiogram was realized by the disk diffusion method, then an amplification of the β-lactamase resistance genes and integrons by PCR was done. Out of the 419 E. coli, 31 isolates (7.4%) harbored the DEC virulence genes. From these DEC, 21 (67.7%) were ESBL-producing E. coli. Susceptibility to ESBL-producing E. coli showed that the majority of isolates were highly resistant to amoxicillin (77.4%), amoxicillin-clavulanic acid (77.4%), and piperacillin (64.5%). The following antibiotic resistance genes and integron were identified: blaTEM (6.5%), blaSHV (19.4%), blaOXA (38.7%), blaCTX-M (9.7%), Int1 (58.1%), and Int3 (19.4%). No class 2 integron (Int2) was characterized. Because of the high prevalence of multidrug-resistant ESBL organisms found, there is a need of stringent pediatric infection control measures.
