We conclude that, in HIV-infected children, atovaquone-azithromycin is as effective as TMP-SMZ for the prevention of serious bacterial infections and is similarly tolerated.

The dicationic macrolide antibiotic azithromycin inhibits the uptake of horseradish peroxidase (HRP) by fluid-phase pinocytosis in fibroblasts in a time- and concentration-dependent fashion without affecting its decay (regurgitation and/or degradation). The azithromycin effect is additive to that of nocodazole, known to impair endocytic uptake and transport of solutes along the endocytic pathway. Cytochemistry (light and electron microscopy) shows a major reduction by azithromycin in the number of HRP-labeled endocytic vesicles at 5 min (endosomes) and 2 h (lysosomes). Within 3 h of exposure, azithromycin also causes the appearance of large and light-lucentlelectron-lucent vacuoles, most of which can be labeled by lucifer yellow when this tracer is added to culture prior to azithromycin exposure. Three days of treatment with azithromycin result in the accumulation of very large vesicles filled with pleiomorphic content, consistent with phospholipidosis. These vesicles are accessible to fluorescein-labeled bovine serum albumin (FITC-BSA) and intensively stained with filipin, indicating a mixed storage with cholesterol. The impairment of HRP pinocytosis directly correlates with the amount of azithromycin accumulated by the cells, but not with the phospholipidosis induced by the drug. The proton ionophore monensin, which completely suppresses azithromycin accumulation, also prevents inhibition of HRP uptake. Erythromycylamine, another dicationic macrolide, also inhibits HRP pinocytosis in direct correlation with its cellular accumulation and is as potent as azithromycin at equimolar cellular concentrations. We suggest that dicationic macrolides inhibit fluid-phase pinocytosis by impairing the formation of pinocytic vacuoles and endosomes.

In this study, we investigated the distribution, phenotypic and molecular typing characters of Campylobacter jejuni in domestic fowl, and livestock populations in East China, to provide some reference for researches on its molecular epidemiology. A total of 1250 samples were collected from different animal sources, and C. jejuni strains were then isolated and tested for antibiotic sensitivity. Antibiotics-resistance gene and pathogenic genes were detected by polymerase chain reaction. Phylogenic analysis on the C. jejuni strains was performed by multilocus sequence typing (MLST) method. The results showed that 108 out of the 1250 samples (mean 8.64%) were C. jejuni positive. These 108 C. jejuni strains were highly sensitive to antibiotics such as chloramphenicol, amoxicillin, amikacin, cefotaxime, and azithromycin, whereas they were highly resistant to antibiotics such as cefoperazone, cotrimoxazole, cefamandole, sulfamethoxazole, and cefradine. Pathogenicity related gene identification indicated that the mean carrying rate of adhesion related gene cadF and racR, flagellin gene flaA, toxin regulating gene cdtA, cdtB, cdtC, wlaN and virB11, heat shock proteins and transferring proteins related genes dnaJ and ceuE, CiaB and pldA were 92.45%, 38.69%, 73.58%, 71.70%, 52.83%, 96.23%, 12.26%, 1.89%, 0.94%, 65.09%, 39.62% and 9.43%, respectively. A total of 58.82% of these strains contained more than 6 pathogenicity-related genes. MLST typed 58 ST types from the 108 isolated C. jejuni strains, including 24 new types, and ST-21 was the major type, accounting for 39.3% of the total strains.
All antepartum obstetrical patients underwent routine screening for chlamydia cervicitis using a DNA probe assay (Gen-Probe Pace, San Diego, CA). Women who tested positive for chlamydia cervicitis were prospectively randomized to receive either azithromycin 1 g orally at enrollment, or erythromycin 500 mg orally 4 times a day for 7 days. Sexual partners were referred to the county health department for evaluation and treatment. A test of cure was repeated in 2 weeks. RESULTS were analyzed by chi-square analysis and Fisher's exact test when indicated.

These are the first sentinel surveillance data for Western Europe for N. gonorrhoeae and they have implications for choice of antimicrobial for treatment of gonorrhoea on a European and a local level. This is the start of the formation of a European gonococcal antimicrobial surveillance programme (EURO-GASP).

Confluent and reticulated papillomatosis (CRP) is a relatively rare disorder of unknown origin, mostly affecting young female adults. We here present the case of a 21-year-old male patient with confluent and reticulated papillomatosis. Skin examination revealed brownish, verrucous, hyperkeratotic, 2 to 5 mm papules, which formed confluent patches and plaques with a reticulate network on the interscapular area. The patient was initially treated with ketoconazole cream for two weeks without improvement. The disease can be rather persistent and resistant to topical therapy. Our case showed a satisfactory response to treatment with azithromycin. Although this treatment is known to be effective in some cases, the action mechanism of azithromycin on CRP is not fully understood.
Induction of ATP Binding Cassette (ABC) proteins involved in chloride transport has been proposed as a possible mechanism of the beneficial effects of azithromycin (AZM) in cystic fibrosis (CF) patients. This study focused on the effects of AZM on mRNA and protein expression of Multidrug Resistance-associated Protein 1 (MRP1) and Multidrug Resistance Protein 1 (MDR1) by real-time quantitative PCR, flow cytometry and gene reporter assays in two CF and two isogenic non-CF airway epithelial cell lines. We detected higher levels of MRP1 and lower levels of MDR1 mRNA in CF versus non-CF cells while both proteins were not differentially expressed. After AZM treatment we found modest differences in MRP1 and MDR1 mRNA expression while protein levels were unaffected. The ability of AZM to regulate MRP1 promoter transcriptional activity was excluded by gene reporter assays. Our data do not support the hypothesis of induction of ABC transporters by AZM.

We collaborated with 26 groups from universities across the United States to sample 42 sites for 33 trace organic compounds (TOCs) in water and sediments of lotic ecosystems. Our goals were 1) to further develop a national database of TOC abundance in United States lotic ecosystems that can be a foundation for future research and management, and 2) to identify factors related to compound abundance. Trace organic compounds were found in 93% of water samples and 56% of sediment samples. Dissolved concentrations were 10-1000× higher relative to sediment concentrations. The ten most common compounds in water samples with detection frequency and maximum concentration were sucralose (87.5%, 12,000ng/L), caffeine (77.5%, 420ng/L), sulfamethoxazole (70%, 340ng/L), cotinine (65%, 130ng/L), venlafaxine (65%, 1800ng/L), carbamazepine (62.5%, 320ng/L), triclosan (55%, 6800ng/L), azithromycin (15%, 970ng/L), diphenylhydramine (40%, 350ng/L), and desvenlafaxine (35%, 4600ng/L). In sediment, the most common compounds were venlafaxine (32.5%, 19ng/g), diphenhydramine (25%, 41ng/g), azithromycin (15%, 11ng/g), fluoxetine (12.5%, 29ng/g) and sucralose (12.5%, 16ng/g). Refractory compounds such as sucralose may be good indicators of TOC contamination in lotic ecosystems, as there was a correlation between dissolved sucralose concentrations and with the total number of compounds detected in water. Discharge and human demographic (population size) characteristics were not good predictors of compound abundance in water samples. This study further confirms the ubiquity of TOCs in lotic ecosystems. Although concentrations measured rarely approached acute aquatic-life criteria, the chronic effects, bioaccumulative potential, or potential mixture effects of multiple compounds are relatively unknown.
