No clinical trials have been conducted in India on the efficacy of parenteral antibacterials to treat footrot in sheep. In addition, there are no studies worldwide on the efficacy of parenteral antibacterials to treat chronic footrot. Sixty two sheep with acute footrot and 30 sheep with chronic footrot from 7 villages in Kashmir, India were recruited into two separate trials. Sheep with acute footrot were allocated to one of three treatments using stratified random sampling: long acting parenteral oxytetracycline, long acting parenteral enrofloxacin and topical application of potassium permanganate solution (a traditional treatment used by sheep farmers in India). In a quasi pre-post intervention design, sheep with chronic footrot that had not responded to treatment with potassium permanaganate were randomly allocated to treatment with one of the two parenteral antibacterials mentioned above. Sheep with acute footrot were treated on day 0 and those with chronic footrot on days 0, 3, 6 and 9. Sheep were monitored for up to 28 days after treatment. Time to recovery from lameness and initial healing of lesions was assessed using Kaplan-Meier survival curves, nonparametric log-rank and Wilcoxon sign-rank tests.. There was significant correlation in recovery from lameness and presence of healing lesions in sheep with acute (r = 0.94) or chronic (r = 0.98) footrot. Sheep with acute footrot which were treated with parenteral antibacterials had a significantly more rapid recovery from lameness and had healing lesions (median = 7 days) compared with those treated with topical potassium permanganate solution (less than 50% recovered in 28 days). The median time to recovery in sheep with chronic footrot treated with either antibacterial was 17 days; this was significantly lower than the median of 75 days lame before treatment with antibacterials. The median time to recovery for both acute and chronic footrot increased as the severity of lesions increased. There was no difference in time to recovery by age, body condition score, duration lame, or presence of pus in the foot within acute and chronically affected sheep.. We conclude that use of parenteral antibacterials to treat sheep lame with either acute or chronic footrot in India is highly effective. This is likely to improve welfare and give economic benefits to the farmers.

Twenty-six elderly patients with chronic leg ulcers infected by Pseudomonas aeruginosa or other aerobic Gram-negative rods were randomised to two treatment groups. The control group (eight patients) received conventional local therapy and the other group (18 patients) was treated with oral ciprofloxacin for three months in addition to conventional local therapy. In the beginning of the study both groups were comparable with the age of the patients and the associated diseases including impairment of arterial and venous circulation in the lower legs. Also the size, duration and the severity of the inflammation reaction in the leg ulcers were comparable before the start of the therapy. Ciprofloxacin was clinically more effective than the standard therapy in reducing the size of the ulcer (p less than 0.05). Also the need of extra systemic antibiotics decreased significantly in the ciprofloxacin group compared with the controls. In three out of eighteen ciprofloxacin treated patients the leg ulcers disappeared completely during the three months' study period compared with none in the control group. However, ciprofloxacin resistant strains, mainly staphylococci, appeared in the leg ulcers in 67% of the ciprofloxacin treated patients compared with 0% in the control group (p less than 0.01). No significant side-effects due to ciprofloxacin except the resistant strains were noticed. We conclude that oral long-term ciprofloxacin therapy is effective in the treatment of chronic leg ulcer infections due to Gram-negative rods but selection of ciprofloxacin resistant strains is a problem in this patient group.
