Several important points regarding the treatment of urinary tract infections should be made. Single-dose and short-course antibiotic therapy is appropriate only for women with acute bacterial cystitis due to E. coli. Studies comparing single-dose to full-course therapy have not been sufficiently designed to draw valid statistical conclusions, and only TMP/SMX is recommended at this time. Recurrent UTI in women is almost always due to reinfection, which is best managed by prophylactic antibiotics. Acute bronchitis and acute exacerbations of chronic bronchitis are often due to viral infections, and therefore antibiotic therapy is not always needed. In acute exacerbations of chronic bronchitis, the clearest success rates for antibiotic therapy have been in patients, who have all three of the following symptoms: increased dyspnea, increased sputum production, and sputum purulence. Mupirocin is an important addition to the agents used to treat bacterial skin infections due to streptococcal and staphylococcal strains. In impetigo, mupirocin has been demonstrated to be as effective or superior to oral erythromycin. In prostatitis, data on the fluoroquinolones appears impressive, but further comparative trials are needed. They may become first-line, empiric therapy. The newer oral antibiotics are not recommended as initial, empiric therapy in the outpatient management of common infections, with the possible exception of the treatment of prostatitis. These newer agents may be more important in the treatment of recurrent or resistant infections.

The pharmacokinetics of trimethoprim-sulphamethoxazole was examined in seven malnourished (marasmic) infants receiving cotrimoxazole (CMZ) for treatment of urinary tract infection. Comparisons were made with the SMZ level of ten nutritionally normal infants, hospitalized for first and second degree burns, receiving CMZ for treatment of bronchitis. CMZ was administered as an oral suspension (20 mg TMP and 100 mg SMZ, 5 ml), patients receiving 22 mg SMZ/kg body weight. Capillary blood samples, 0.05 ml were taken at prescribed intervals. Elimination half-life of SMZ in the marasmic infants was prolonged, 9.6 vs 4.9 hr, in their eutrophic counterparts. In addition, greater area under the curve (AUC), 573 vs 328 micrograms/ml/h, was noted in the malnourished group. This disparity may be due to differences in body fluid distribution between the two groups.

Rational outpatient therapy restricts antibiotics to infections where they are beneficial and selects substances based on local resistance patterns. Respiratory tract infections typically caused by viruses should not be treated with antibiotics (e.g., rhinitis, bronchitis, sinusitis). Many respiratory infections likely caused by bacteria can be treated with aminopenicillin, sometimes combined with a beta-lactamase inhibitor. Quinolones should be used only as exception for respiratory tract infections, since resistance is rising. For this reason uncomplicated urinary tract infections (cystitis) should be treated with trimethoprim-sulfa-methoxazole (TMP-SMX) instead of quinolones, even though approximately 20% of Escherichia coli are resistant to TMP-SMX. Skin and soft tissue infections are best treated with beta-lactam antibiotics, as long as the community acquired methicillin-resistant strains of S. aureus frequently seen in certain countries remain uncommon here.

Salmonella spp. are important food borne pathogens worldwide that frequently infect poultry flocks. This cross-sectional study was conducted to determine the prevalence of Salmonella spp. colonization in broiler flocks in Shiraz (southern Iran) and to find the possible association of infection status with some potential risk factors including vaccination program and use of antibiotics. During October 2009 to April 2010, a total of 40 broiler flocks were selected in slaughterhouse and 20 cloacae contents were collected from each flock. Every five cloacae contents were pooled and investigated for Salmonella spp. using appropriate culture methods. The flock was considered positive if any of the pooled samples turned positive in culture. Statistical analysis was performed using multiple logistic regression. Nine out of 40 flocks (22.50%, 95% CI: 9-36) were positive for Salmonella spp. colonization. Nearly 75.00% of flock owners reported that they used antibiotics during production period, more frequently fluoroquinolones, combination of trimethoprim-sulfonamides (TMP/SU) and tetracycline. Nearly 60.00% of the flocks which had used TMP/SU were positive for Salmonella spp. compared with 10.00% of the flocks which did not use this antibiotic (p = 0.006). Increasing flock age was associated with a decreased chance of Salmonella spp. detection (p = 0.003). In flocks which received infectious bronchitis vaccine, 36.00% were positive for Salmonella spp. whereas this was 15.00% for flocks which did not receive this vaccine (p = 0.08). Careful monitoring of antibiotics use and further studies to determine the most appropriate vaccination program in the field is recommended.
