This report describes the first case of deep neck infection resulting from Lactococcus lactis subsp. cremoris. The case is associated with the consumption of unpasteurized milk and occurred in a patient with a buccal mucosa tumor. Anti-infective therapy with ceftriaxone and metronidazole resulted in complete resolution.
These materials might cause antibacterial effects against S. mutans when placed on cavity surfaces in both enamel and dentine, thereby preventing secondary caries formation.
Here, we report a laboratory-developed colorimetric-plate method for rapid disk diffusion susceptibility testing of Escherichia coli. One hundred isolates were evaluated. Categorical agreement between the colorimetric plate and the standard disk diffusion method was 99%. Mean time to results was 7.07 h (95% confidence interval, 5.96 to 8.19).
June 2011 were included. Conventional methods and Vitek 2 Compact (bioMérieux-SE, France) automated systems were used for the identification and antibiotic susceptibility of the isolates. Results: During the study period, a total of 3.212 Acinetobacter species were isolated. Species distribution of Acinetobacter isolates and their ratios were found as follows: Acinetobacter baumannii-Acinetobacter calcoaceticus complex (n=3006; 93.6%), Acinetobacter lwoffii (n=83; 2.6%), Acinetobacter junii (n=27; 0.8%), Acinetobacter haemolyticus (n=19; 0.6%) and Acinetobacter spp. (n=77; 2.4%). Acinetobacter isolates were isolated at the most from tracheal aspirate samples (n=747; 23.2%) and samples sent from intensive care units (n=705; 21.9%). Ceftazidime resistance increased from 70.2% to 82.7%; cefepime from 26.4% to 79.7%; imipenem from 27.2% to 77.2%; meropenem from 4.5% to 77% and ciprofloxacin from 40.4% to 78.9% in the last six years. In the first six months of 2011, the resistance ratios to tigecycline and colistin were determined as 5.9% and 0.2% respectively. No significant changes were observed in ampicillin-sulbactam resistance ratios. ÖZET Amaç: Son altı yılda, hastanemizde izole edilen Acinetobacter türlerinin dağılımı ve antibiyotik duyarlılıklarının incelenmesi amaçlanmıştır.
The aim of this study was to retrospectively analyze the frequency of anti-hepatitis delta virus (anti-HDV) antibody in hepatitis B virus surface antigen (HBsAg)-positive cases. Materials and Methods: Anti-HDV and anti-hepatitis B virus core antigen (anti-HBc) IgM seropositivity was researched using ELISA method in patients who attended the clinical microbiology laboratory at Ondokuz Mayıs University Medical Faculty Hospital between August 2005 and August 2010 and were determined to be positive for HBsAg. Results: A total of 2314 HBsAg-positive patients were included in this study. Anti-HDV positivity was detected in 36 (1.56%) of them. By taking the anti-HBc IgM seropositivity as reference, among patients who had positive delta antibody, 33 (91.67%) subjects were evaluated as "super-infection" and 3 (8.33%) patients were evaluated as "co-infection". Conclusion: Although anti-HDV positivity in our region is relatively lower than in the other regions, emphasis should be given to the prevention and monitoring researches due to the high level of mortality and morbidity of the illness.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
