Hi as per the history provided by you with fever last 2 weeks and S.typhi positive for 1:160 it seems that the cause of your fever is infection with Salmonella typhi. Now the value in your history 1:160 (dilution rate) is the titre of the antibody produced by your body in trying to protect you from the organism (S typhi) in your case. Now the titre (dilution rate) of 1:160 is significant and suggestive of S typhi infection. The normal titre (dilution rate) is below 1:80 in endemic regions of India that is value below this titre doesn't signify infection and this much value we get in normal people also.
