Ampicillin resistance dropped from 35% to 30%, nitrofurantoin resistance dropped from 93% to 92%, and nalidixic acid
resistance remained steady at 97%.
Todd-Hewitt broth supplemented with either colistin (10 [mu]g/mL) and nalidixic acid
(15 [mu]g/mL) or with gentamicin (8 [mu]g/mL) and nalidixic acid
(15 [mu]g/mL) may be used; appropriate commercially available options include Lim or SBM broth.
Ciprofloxacin, Norfloxacin, Linezolid, Meropenem, Nalidixic Acid
, Nitrofurantoin, Tobramycin and Cefazolin.
India, Pakistan, Bangladesh) often are resistant to the quinolone nalidixic acid
or are multidrug resistant (i.
However, the direct antimicrobial susceptibility plates revealed dual zones of inhibition around nalidixic acid
Merseyside, UK): Ampicillin (10ug), Chloramphenicol (30ug), Cefuroxime (30ug), Ceftriaxone (30ug), Gentamycin (30ug), Cotrimoxazole (25ug), Nalidixic Acid
(30ug), Ciprofloxacin (5ug) and Augmentin (30ug).
Over a decade ago, results of active surveillance studies showed that, in most endemic countries, especially in Asia and sub-Saharan Africa, there was an emergence of multidrug resistance to different antimicrobials, including ampicillin, co-trimoxazole, and nalidixic acid
All cry4 positive Bt isolates and positive controls of cry4 gene IPS78 and HD500 were found resistant to ampicillin, amoxicillin and bacitracin and were sensitive to chloramphenicol, erythromycin, kanamycin, neomycin, nalidixic acid
, oxytetracyclin, polymixin, streptomycin, tetracyclin and vancomycin.
The antimicrobial susceptibility tests included the following drugs: amikacin (an aminoglycoside), cephalexin, cefuroxime and cephotaxime (1st, 2nd and 3rd generation cephalosporins, respectively), norfloxacin, ciprofloxacin and nalidixic acid
(fluoroquinolines), nitrofurantoin, ampicillin, and trimethoprim-sulfamethoxazole (TMP/SMX).
cholerae isolates were sensitive to tetracycline, gentamycin and azithromycin but resistance for ampicillin, co-trimoxazole, nalidixic acid
, and furazolidone.
group B streptococcus infection was detected in 21 patients by using the cheaper, more rapid colistin and nalidixic acid
agar (CNA) culture system.
Based on these findings, MSF emphasized treatment of dysentery with a complete course of nalidixic acid
and improvement of basic sanitation and hygiene.
