These 18 TMP-resistant E. coli were also resistant to ampicillin ( 44 % ) , azithromycin ( 11 % ) , chloramphenicol ( 39 % ) , ciprofloxacin ( 11 % ) , doxycycline ( 89 % ) , erythromycin ( 100 % ) , furazolidone ( 72 % ) , levofloxacin ( 17 % ) , trimethoprim-sulfamethoxazole ( 89 % ) and trovafloxacin ( 17 % ) .
Emergence of trimethoprim-resistant Escherichia coli in healthy persons in the absence of prophylactic or therapeutic antibiotics during travel to Guadalajara, Mexico. Thirty-nine healthy US students without diarrheal disease and who had not received prophylactic or therapeutic antibiotics were monitored for emergence of trimethoprim-resistant gram-negative fecal flora for a 3-week period after arrival in Guadalajara, Mexico. During this time period, most students showed no change in total fecal gram-negative bacteria (p > 0.05) but showed an increasing level of trimethoprim (TMP) resistance (p < 0.01) among fecal coliforms. Escherichia coli was the TMP-resistant organism isolated in 18 of 39 (46%) healthy students. These 18 TMP-resistant E. coli were also resistant to ampicillin ( 44 % ) , azithromycin ( 11 % ) , chloramphenicol ( 39 % ) , ciprofloxacin ( 11 % ) , doxycycline ( 89 % ) , erythromycin ( 100 % ) , furazolidone ( 72 % ) , levofloxacin ( 17 % ) , trimethoprim-sulfamethoxazole ( 89 % ) and trovafloxacin ( 17 % ) . In the absence of prophylactic and therapeutic antibiotics, increased acquisition of TMP-resistant gram-negative fecal flora in this developing country is probably due to poor sanitary conditions and the recurrent and heavy exposure to antimicrobial-resistant indigenous flora as a result of contaminated food and drink.
