I have recurrent paratyphi bacteria (BH, O), every few months (tretament with doxylina dn ciprofloxacin). Does it mean that it remains in my system and then gets activated whenever my immunity is low or that I get infected each time from an external source? Thank you
HIT hanks for posting your query to Chat Doctor.  It could be either way. In your case I think it has remained in your system due to improper treatment. Roxy is not an antibiotic of choice for paratyphoid infection and these days there is a lot of resistance to Cipro.  So I feel your infection is not treated properly and hence it is recurring.Also, the duration of treatment plays a significant role in curing infection.  My antibiotic of choice for Paratyphoid infection is Definite with Of lox combination. Kindly ask your doctor for this prescription and use it for 7 days.  Also, Chat Doctor.  Hope this information was useful to you. Any clarifications feel free to ask. Regards.
