Erythromycin, 50mg kg day, 4 times daily for 7 to 14 days or 1 gr. Azythromycin as single dose are the treatments of choice for children or pregnant women and for adult patients that for any reason cannot take tetracycline. A single-dose 1 gr. oral Azytromycin is an alternative for the uncomplicated chlamydial cervicitis and urethritis. This treatment is equivalent to standard therapy with doxycycline 27, 28 ; . Azytromycin can be given where the causative pathogen of urethritis cervicitis is uncertain, and it is often, therefore, most useful in acute therapy where there is no immediate microbiological back-up 29 ; . Ofloxacin 200mg twice daily for 7 days is also very effective. As with the tetracyclines, it is contraindicated for pregnant women and for children. In many places the confirmation of the diagnosis is impossible. The syndromic treatment tables 1 and 2 and the adeguate follow up is the option in this situation. 2. Other causes of NGU C. trachomatis is the responsible of 30 to 40% of NGU, and Ureaplasma urealyticum is detected in up to 40%. Mycoplsmas, mainly U. urealyticum and Mycoplasma hominis, are normal commensal organisms of the genital tract, which sometimes makes it difficult to determine their pathogenicity. However they are responsible for urogenital infections, and U. urealyticum is a pathogen in male urethritis 30 ; . The treatment is the same for both. Trichomonas vaginalis, herpes simplex virus, and Candida spp. are the single causative organism of the NGU in approximately 1-2%. Stahphylococcus, Streptococcus and E. coli may cause NGU. In most of the patients the signs and symptoms of NGU are similar for the different pathogens. In as many as 20-30% of patients no known pathogen can be isolated 17 ; . Whenever possible, the treatment should be oriented in accordance with the isolated agent. As already mentioned, the tetracyclines are the treatment of choice for NGU caused by C. trachomatis and U. urealyticum. If the microbiological diagnosis is not available, the syndromic treatment is recommended tables 1 and 2.

M. O'Donoghue, M. Boost, R. Yim. The Hong Kong Polytechnic University, Hong Kong, China Introduction: Strains of S. pneumoniae co-resistant to tetracycline and erythromycin are usually a result of site-specific recombination of two genes, namely tet M ; and erm B ; in the Tn1545-like transposon. The erm B ; gene encodes for the production of a methylase that modifies the antibiotic-receptor site in the bacterial ribosome, while tet M ; gene encodes for the TetM protein, which affords ribosomal protection. The integrase gene Int-Tn ; in the Tn916-Tn1545 family encodes for an integrase that binds the genes together by site-specific recombination giving resistance to both antibiotics. Methods: One hundred and forty-six clinical isolates of S. pneumoniae were tested for resistance to erythromycin and tetracycline using disc diffusion susceptibility testing following CLSI guidelines. DNA was extracted from strains resistant to both antibiotics, and was used in a polymerase chain reaction PCR ; to amplify the integrase gene. The amplification products were detected on 1% agarose gel and visualized with ethidium bromide. Successful amplification of the DNA was confirmed by inclusion of a pneumococcal housekeeping gene for pneumolysin, ply. Results: A total of 35 strains 24% ; were found to be resistant to both antibiotics. PCR amplification resulted in detection of the integrase gene in 33 of these strains. In the remaining two strains, only the ply gene was amplified. Conclusions: The majority of co-resistant strains revealed the presence of the integrase gene, confirming that the well-recognised mechanism of site-specific recombination responsible for insertion of resistance determinants for tetracycline and eythromycin into the pneumococcal genome had occurred in most isolates. The absence of the gene in two strains may indicate that another mechanism for incorporation may be occurring, or that the gene present has multiple mutations leading to a failure to amplify. In a related study on these strains, it was noted that two strains did appear to have an unusual erythromycin resistance mechanism. Further characterization of these strains is needed.

Clinical Trials Four randomized, double-blind, controlled studies and four open-label studies of telithromycin for the treatment of community-acquired pneumonia were reviewed during the approval process for telithromycin. Only patients with mild to moderate infection appropriate for outpatient treatment were included in the studies. In the overall population, clinical cure rates were as shown in Table 4. Among patients with multi-drug resistant Streptococcus pneumoniae, clinical cure rates were 86.9% for patients with penicillin-resistant Streptococcus pneumoniae, 90.9% for patients with second-generation cephalosporin-resistant isolates, 89.3% for patients with macrolide-resistant Streptococcus pneumoniae, 88.9% for patients with trimethoprim sulfamethoxazole-resistant infection, and 84.6% for patients with tetracycline-resistant Streptococcus pneumoniae. Safety and efficacy in the setting of acute bacterial sinusitis was evaluated in two randomized, double-blind, comparative studies. Clinical cure rates for amoxicillin clavulanic acid 500 125 mg three times daily for 10 days versus telithromycin 800 mg once daily for 5 days were 75.3% and 74.5%, respectively. For 5 days of telithromycin versus 10 days of cefuroxime 250 mg twice daily, clinical cure rates were 85.2% versus 82.0%. Clinical cure rates by pathogen were similar for telithromycin and the comparator drug, with the and tramadol. This reduces the risk that the drug will cause a hangover effect the day after it is taken. Effectiveness Generally, field studies conducted to demonstrate drug effectiveness for a NADA should closely mimic the actual conditions of use. However, attempting to conduct field studies at aquatic production facilities poses a logistic dilemma. To reduce animal numbers to a manageable size, the studies can be conducted on a smaller scale, while maintaining conditions similar to those found at the production facility. However, even with this compromise, small ponds 0.25 acres ; or small tanks 700 gallons ; , with fish densities similar to those at industry production level, may contain several hundred to several thousand fish. This makes the collection of clinical data, such as mortality, feed consumption, or changes in fish behavior, difficult to capture. With warm water temperatures, dead fish may degrade quickly or sink to the bottom of a murky pond before being counted or collected. Catfish in a typical pond are frequently not visible except at feeding. For fish reared in clear water, such as trout or salmon raised in netpens with underwater cameras, the collection of some types of data may be easier owing to improved visibility. However, studies involving offshore netpens necessitate the collection of data on pontoons located alongside the netpens. Under these conditions, the collection of data is highly dependent on weather conditions. Antimicrobials that are approved for use in other food-producing species are commonly investigated for use in fish. This is because an approved drug product that can be administered to fish often is available. Since certain types of data can be used for approvals in multiple species, specifically some of the human food safety data, the cost of adding an indication to an approved product for use in aquatic species is thereby reduced. However, when compared with mammals, fish have some definite differences in pharmacokinetics that need to be considered. For example, differences in bioavailability of tetracycline, quinolones, and beta-lactam antimicrobials have been documented. Oxytetracycline and amoxicillin are not well absorbed from the intestines of fish. The doses of these antimicrobials are generally 2 to 5 times that needed to produce therapeutic systemic concentrations in mammalian species.19 The bioavailability of oxytetracycline in rainbow trout in fresh water may be as low as 8% and as low as 2% in Atlantic salmon living in seawater. Trimethoprim and ormetoprim are almost completely absorbed from the fish intestine and have a high volume of distribution, but the systemic availability of sulphonamides in Atlantic salmon in seawater is less than 40%. For several antimicrobials, the cations present in seawater consumed for osmoregulation and in feeds inhibit the absorption of antimicrobials from the intestine. Tetracyclines and quinolones chelate with di- and trivalent cations with the level of binding varying among the drugs in each antimicrobial class. Serum concentrations of oxolinic acid and difloxacin were found to be 2 times higher in fish held in fresh water than for fish held in salt water.19 and valaciclovir. REFERENCES 1. Abraham, L. J., D.

The N. gonorrhoeae population transmitted in Arkhangelsk, Russia is highly divergent from the bacterial populations in several West-European countries, for example, Sweden, Scotland, and England. In Arkhangelsk, Russia and presumably other areas of Russia, penicillins, ciprofloxacin, erythromycin, azithromycin, kanamycin, and tetracycline should not be used for treatment when results of antibiotic susceptibility testing are unknown. In Russia, surveillance of the antibiotic susceptibility in order to identify emergence of new resistance, to monitor the changing patterns of the susceptibility, and to be able to update treatment recommendations on a regular basis is essential. Serovar determination remains a fairly effective, rapid, inexpensive, and easily performed alternative to genetic characterisation in low-resource countries. In addition, also in other countries serovar determination can be a useful primary epidemiological marker, which can supplement the genetic characterisation and also provide valuable data regarding, for instance, exposure of immunologically important epitopes and vardenafil.
STRUCTURAL STABILIZATION OF HUMAN SOD1 BY BINDING OF TETRACYCLINES TO ITS ZN SITE David Frost * , Avijit Chakrabartty Princess Margaret Hospital Introduction: Therapeutic options for amyotropic lateral sclerosis ALS ; are extremely limited. Minocycline, a tetgacycline derivative antibiotic, extends lifespan in mouse models for ALS, and human trials are underway. Several mechanisms of action for minocycline involving inhibition of apoptosis and anti-inflammatory effects have been reported. Hypothesis: It has been shown that the aggregation of superoxide dismutase, SOD1 ; , which is likely involved in the pathogenesis of ALS, is determined by the stability of its Zn atom. Given the zinc-binding mechanism of tetracyclines'inhibition of matrix metalloproteases, tetracyclines may bind to the zinc site of SOD1 and stabilize it against aggregation. We have taken advantage of the fluorescent properties of its parent compound, tetracycline, to determine whether it binds to SOD1 in vitro. Results: Tetraxycline binds to SOD1 with a binding constant Kd ; of ~18mM. The fluorescent behaviour of tdtracycline in the presence of SOD1 is the same as its behaviour in the presence of free zinc. Zinc also competes with SOD1 for binding tetracycline, and vice-versa. EDTA, a metal chelator, competes with tetracyclinne for SOD1 binding. These binding experiments were performed by observing changes in the fluorescence of tetracycline under different experimental conditions. Analytical ultracentrifugation experiments demonstrated the excitation peak for minocycline at the molecular weight of SOD1, confirming that minocycine binds to SOD1 as well. Minocycline and tetracycline both stabilize SOD1 against thermal unfolding; the melting temperature Tm ; of SOD1 is increased by approximately 4C in the presence of minocycline, and 7C in the presence of tetracycline. Conclusion: The structure of tetracycline which does not cross the blood-brain barrier ; is very similar to that of minocycline, particularly in its metal binding region, which is identical. The data we obtained for tetracycline likely holds true for minocycline, suggesting a novel ALS-specific additional mechanism of action for the drug. Minocycline may bind to the Zn site of SOD1 in motor neurons and stabilize it against unfolding and aggregation.

6.9. Testing antimicrobial susceptibility The antimicrobial susceptibility of bacteria can be determined in vitro by standardised methods such as disk diffusion method and broth or agar dilution assay NCCLS 2002 ; . Disk diffusion method is convenient in screening of resistance phenotypes presence of the resistance genes ; while dilution assay determines the precise level of resistance. In disk diffusion method the size of growth-inhibiton zone around a filter paper disk containing the antibiotic on agar plate determines the susceptibility of the culture, and in antimicrobial dilution assay minimal inhibitory concentration MIC ; is determined as inhibition of growth within a series of antibiotic dilutions in broth or on agar. MIC can also be tested on agar using commercial E-test strips containing stable increasing antibiotic gradient producing a growth-inhibition ellipse and voltaren.
