Profiling the occurrence of 143 HPV types and 6 Salmonella isolates across 26 gall bladder cancer patients. Heat map representation of 6 Salmonella isolates (in row) found across 26 gallbladder samples -- 17 tumours and 9 matched normal (in column) is shown. Solid boxes indicate presence of reads from Salmonella genome in the corresponding gallbladder sample. The samples (column) have been grouped based on gender as shown above the heat map. Solid boxes in the first row indicate presence of HPV16 sequence. Solid boxes in the second row indicate the presence of mutation in TP53. Reads of HPV16 were found in 1 of 26 samples (10 T). 9 of 17 gallbladder tumour samples were associated with gall stones as shown by solid boxes in the second row. Typhoidal Salmonella isolates were found in 11 of 26 gallbladder cancer samples, non-typhoidal Salmonella isolates were found in 12 of 26 gallbladder cancer, with 6 of 26 samples co-infected with both
