To determine the antibiogram of the isolated strains, we selected different antibiotics like ampicillin, nitrofurantoin, tetracycline, cefotaxime,
nalidixic acid, ciprofloxacin, co-trimoxazole, meropenem, imipenem, chloramphenicol, gentamicin and piperacillin-tazobactum (16).
coli isolated from dogs were susceptible to
nalidixic acid and ciprofloxacin.
The numbering system of compounds from left to right is as follows: piroxicam (7),
nalidixic acid (6), cinoxacin (8), difloxacin (3), enrofloxacin (10), pefloxacin (4), ofloxacin (1), lomefloxacin (9), ciprofloxacin (2), and pipemidic acid (5).
pylori Using
Nalidixic Acid and Cephalothin Antibiotics.
Resistance to
nalidixic acid alone or in combination with other drugs was observed in 24% and 17.6% of isolates from eastern and central regions, respectively.
Evaluation of the current trend of
Nalidixic Acid succeptibility in typhoidal Salmonella; a marker of therapeutic failure for the fluoroquionolones.

Overall resistance to FQs tested was almost similar: moxifloxacin (74.4%) ciprofloxacin (79.3%), sparfloxacin (80.1%), ofloxacin (80.3%), norfloxacin (80.9%) and enoxacin (81.8%) with greater resistance to
nalidixic acid (91.7%).
Nalidixic acid have maximum of all biological activities, but H-6 showed slightly better antioxidant activity than
Nalidixic acid and other activities were close to it.
In vitro antibacterial activity of AM-715, a new
nalidixic acid analog.
Among 88 isolates, 72.7% were
nalidixic acid resistant Salmonella (NARS) which include Salmonella Typhi (58, 78.4%) and Salmonella Paratyphi (6, 42.9%).
There were intermittent zones of inhibition to the claforan,
nalidixic acid, amoxycillin, fosfomycin, fortum, and erythromycin (Table 3).
