The use of RIT is associated with a marked reduction in symptoms, which was sustained for over 24 weeks.

To describe the rate of response to an antibiotic-lock technique (ALT) in the treatment of venous access port (VAP)--related bacteremia and to analyze the role of the reservoir in the persistence of infection, we reported the data from 12 human immunodeficiency virus--infected and 8 oncologic patients with VAP-related bacteremia. The ALT consisted of intracatheter delivery of antibiotics and was associated with a systemic antibiotic infusion. We monitored clinical manifestations and performed qualitative and quantitative blood cultures during and at the end of the treatment. Four patients had catheters removed before antibiotic treatment. Of the 16 patients who were treated with the ALT, 5 (31%) were cured, as determined by negative cultures of blood and of samples from the catheter; 2 (12.5%) were cured but had recurrent infection with another microorganism; and 9 (56%) had persistent positive cultures of blood and of samples from the tip, reservoir, or both of the VAP. Limited efficacy of the ALT might be explained by the presence of deposits of fibrin that include clusters of bacteria inside the reservoir of the port.

Advanced age, occurrence of IE on presumably normal valves, high rate of neurologic complications, associated gastrointestinal diseases and low mortality rate during initial follow-up are characteristic features of S. bovis IE observed in this study.

Aims:  The activity of two essential oils (EOs) of Cinnamosma fragrans, an endemic plant to Madagascar (B8: linalool‐type and B143: 1,8‐cineole‐type), against bacterial isolates from a shrimp hatchery of Penaeus monodon and their effects on the survival and bacterial concentration of larvae were determined. Methods and Results:  Minimum inhibitory concentrations were determined using a broth dilution technique. The bacterial concentrations of both larvae and water tank were assessed on Marine agar and Thiosulfate Citrate Bile Sucrose agar. The assays took place in OSO Farming’s shrimp hatchery in Madagascar. EOs were directly added to the water tank. Regarding the survival, the assays in larval culture (four replicates each of B8, B143, E and control) showed that B8 oil had a similar effect (P > 0·05) as the antibiotic (Erythromycin) and was more active than B143 (P < 0·05). A negative correlation was observed between the bacterial concentration and the survival of larvae for all assays. Conclusion:  Both C. fragrans essential oils, as antibiotic, exhibited significantly higher survival rates and lower bacterial concentrations of the larvae than the control (oil and antibiotic free). Significance and impacts of the study:  The potential of C. fragrans essential oil to control the bacterial load in in vivo conditions, thereby enhancing survival rate of P. monodon larvae, makes it a relevant option for developing a novel alternative to antibiotics in shrimp hatchery culture.
