With high annual mortality rates among young children, antimicrobial resistant salmonellosis is considered a major public health concern worldwide. Antimicrobial resistant salmonellosis is a worldwide health issue, particularly in low income countries with high microbially-derived food contaminations. As a result, it is important to better understand the biological factors that may control these bacteria’s dissemination low immunity individuals such as children. Thus, a sound epidemiological surveillance and control of salmonellosis (that is, tet and catA1) requires a better understanding of the role that class 1, 2 and 3 integrons play in the spread of these antimicrobial resistant genes. A total of 275 stool samples of children suffering of diarrhea in rural Burkina Faso were collected and their Salmonella species were screened. The antimicrobial resistance determinants were investigated by Polymerase Chain Reaction, checking the presence of class 1, 2, 3 integrons, tet and catA1 resistance genes. Seven of the nine confirmed Salmonella strains (78%) were multidrug resistant while 100% were resistant to amoxicillin. Antibiotic resistance genes catA and tet were present in 11.1 and 22.2%, respectively. Integrons were detected as follows: Int1 (44.4%) and Int2 (22.2%). No class 3 integron was detected. A surveillance and control programme of antimicrobial drug resistant Salmonella species is of paramount importance for limiting spread of these pathogens among children.
Key words: Antibiotic resistance genes, Class 1 and 2 integrons, Salmonella, children.
