摘要：

Dengue virus infections and typhoid fever are among the endemic diseases in tropical and sub tropical regions of world. Bacteraemia with dengue co-infection is rare. Present study was designed to detect dengue virus RNA and then to test those samples for the detection of S typhi to check the co infection rate of these two infectious agents in Pakistani population. A total of 365 subjects were included in this study, out of which 224 (61.7%) were males and 141(38.2%) were females. The median age of patients was 40 +/- 32, percentage of dengue positive samples was found to be higher in age group 31y-40y and 41y-50y.75 % of total samples included in the study were positive for dengue virus RNA where as 24.6% were those in which dengue virus RNA was not detected. DENV-2 was found to be the most prevalent serotype while DENV-1, DENV-3 and DENV-4 were not detected in any of the sample. Of the 274 samples with DENV-2, only 4 samples were positive for S typhi. S. typhi was also detected in 3 patients who were negative for dengue virus PCR. The presence of S. typhi in dengue positive samples was further confirmed by sequencing PCR products.
