results two bacterial types, st208, and st218, were identified in all 140 samples. the st208 mainly came from icu and department of respiratory medicine, while st218 from department of plastic surgery; 70.21% of st208 and 84.78% of st218 were carbapenem-resistant acinetobacter baumannii (crab) and carbapenem-susceptible acinetobacter baumannii (csab), respectively. multidrug-resistance genes in...

conclusions sequence and structural diversity of the 3'utr variable region and poly u/uc region found in the local isolates indicate specificity in the regulating elements of 3'utr that might be associated with differential replication efficacy of the hcv pakistani isolates. the study necessitates functional characterization of these regulating elements to elucidate variable viral eff...
