INTRODUCTION Helicobacter pylori is a bacteria which infects half the world population and is an important cause of gastric cancer. The eradication therapy is not always effective because resistance to antimicrobials may occur. The aim of this study was to determine the susceptibility profile of H. pylori to amoxicillin, clarithromycin and ciprofloxacin in the population of Southern Brazil. M...
The aim of the study was to establish the in vitro sensitivity of S. agalactiae (126 strains), S. dysgalactiae (82 strains), S. uberis (419 strains), and Enterococcus sp. (136 strains) isolated from mastitis in cows to 13 antibiotics. Bacteriological examinations of quarter milk samples were conducted with the recommendations of the IDF. Sensitivity to antibiotics was tested by disk diffusion m...
Periodontitis is a bacterial disease that can be treated with systemic antibiotics. The aim of this study was to establish the antibiotic susceptibility profiles of five periodontal pathogens to six commonly used antibiotics in periodontics. A total of 247 periodontal bacterial isolates were tested for susceptibility to the six antibiotics using the Etest method. MIC(50) and MIC(90) values (min...
Quality Attributes and In Vitro Bioequivalence of Different Brands of Amoxicillin Trihydrate Tablets
Bacterial resistance and antibiotic drug effectiveness can be related to administering generic products with a subtherapeutic dose or poor in vivo drug release. The aim of this study was to investigate whether locally marketed amoxicillin tablets have the required chemical and physical attributes, including in vitro bioequivalence performance. Five generic products (T1, T2, T3, T4, and T5) cont...
A high rate of resistance (49.5 to 72.7%) to amoxicillin (AMX) was observed in Helicobacter pylori after two or three unsuccessful eradication attempts. Unsuccessful eradication regimens significantly increase resistance to not only clarithromycin (CLR) and metronidazole (MNZ) but also AMX.
Neisseria gonorrhoeae antimicrobial resistance (AMR) is a globally recognized health threat; new strategies are needed to enhance AMR surveillance. The Northern Territory of Australia is unique in that 2 different first-line therapies, based primarily on geographic location, are used for gonorrhea treatment. We tested 1,629 N. gonorrhoeae nucleic acid amplification test-positive clinical sample...
Lincomycin, chlortetracycline, and amoxicillin are commonly used antimicrobials for growth promotion and infectious disease prophylaxis in swine production. In this study, we investigated the shifts and resistance development among intestinal microbiota in pregnant sows before and after lincomycin, chlortetracycline, and amoxicillin treatment by using phylogenetic analysis, bacterial enumeratio...
BACKGROUND The prevalence of resistance to clarithromycin and metronidazole has considerably increased, with a corresponding decrease in the eradication rate for Helicobacter pylori (H. pylori) infection. Primary resistance to amoxicillin is extremely low, and esomeprazole was found to exert a noteworthy antimicrobial activity in vitro against H. pylori. A dual therapy with high-dose of esomepr...
BACKGROUND Empiric treatment of community-acquired urinary tract infections (CA-UTI) is determined by the antibiotic sensitivity patterns of uropathogens in a population. This study was conducted to determine patterns of resistance amongst CA-uropathogens in India, to help establish local guidelines on treatment of CA-UTI. METHODOLOGY 531 consecutive positive urine cultures taken from adult n...
Uncomplicated urinary tract infections (UTI) are common in primary care. Whilst primary care physicians are called to be antimicrobial stewards, there is limited primary care antibiotic resistance surveillance and physician antibiotic prescription data available in southern Chinese primary care. The study aimed to investigate the antibiotic resistance rate and antibiotic prescription patterns i...
