Fig. 1From: Co-existence of extended-spectrum β-lactamases blaCTX-M-9 and blaCTX-M-15 genes in Salmonella species isolated from febrile and diarrhoeagenic patients in Lagos, Nigeria: a cross-sectional studyCorrelation analysis determining the associations between virulence and resistance genes among non-typhoidal Salmonella isolates from hospitalised patients in Lagos, Nigeria. The red boxes indicate positive association, while the strength of colour corresponds to the numerical value of the correlation coefficient (r). Significance was calculated at P < 0.05, and boxes with non-significant correlations were left blankBack to article page
