A five-center collaborative study was undertaken to develop quality control and specific interpretive criteria for susceptibility testing of Streptococcus pneumoniae against 12 antimicrobial agents. MICs were determined for 248 pneumococcal clinical isolates (with an emphasis on resistant strains) by use of the National Committee for Clinical Laboratory Standards (NCCLS)-recommended broth micro...

background and objectives: neisseria gonorrhoeae is the second most sexually transmitted diseases agents in developing countries. antimicrobial resistance strains have created serious health concern. the aim of this study was to determine the frequency of endocervical gonococcal infection and antimicrobial susceptibility of n.gonorrhoeae in kashan, iran. materials and methods: in this study, 29...

Ticarcillin and clavulanic acid in combination were tested against 40 Pseudomonas aeruginosa isolates resistant to ticarcillin by disk diffusion. A total of 21 isolates (53%) were susceptible to ticarcillin-clavulanate by disk diffusion, under currently recommended criteria for ticarcillin susceptibility. Macro-broth dilution tests (ticarcillin plus clavulanic acid, 2 micrograms/ml) confirmed s...

BACKGROUND AND PURPOSE A simplified antifungal disk diffusion test using Mueller-Hinton agar containing 2% glucose and methylene blue 5 microg/mL (GM-MH, Clinical and Laboratory Standards Institute [CLSI] M44-A) has proved to correlate well with the standard reference test. A new azole, voriconazole, has recently been approved for clinical therapy in Taiwan. This study investigated the reliabil...

conclusions due to the variable nature of antibiotic susceptibility patterns and etiological agents of septicemia, continual assessment of the most frequent pathogens associated with bloodstream infections and detection of their sensitivity patterns to locally available antibiotics seem to be reasonable measures. results from a total of 491 blood cultures, 74 (15.1%) samples were detected as po...

results the present study indicates that carbapenems and new cephalosporin antibiotics were practically ineffective against the extensive drug resistance (xdr) strains. colistin was observed to be more effective, although in seven cases resistance to colistin observed. ampc β-lactamase and mbl could be an important contributory factor for imipenem resistance among the isolates in our hospital. ...

Nanotechnology can be a valuable ally in the treatment of infections. Silver nanoparticles (AgNPs) are structures that have antimicrobial activity. The aim of this study was to produce AgNPs by green methods, characterize these structures, and assess their antimicrobial activity against Escherichia coli associated with the antibiotic ciprofloxacin. AgNPs were characterized by spectroscopic and ...

The aim of this study was to determine antimicrobial resistance patterns of Staphylococcus aureus isolated from bovine subclinical mastitis. California Mastitis Test was used for 2,160 quarters of 540 dairy cattle in 8 commercial dairy farms of Alborz province, Iran. Antimicrobial susceptibility test was performed by the disk diffusion method on Mueller Hinton agar. The results indicated that S...

H. parasuis isolates (n=112) from pigs were tested for antimicrobial susceptibility against 23 antimicrobial agents by the disk diffusion method. All isolates were sensitive to Florfenico and most strains were sensitive to Cefotaxime (103/112; 92%), Ceftazidime (99/112; 88.4%), Chloramphenicol (90/112; 80.4%) and Gentamicin (85/112; 75.9%). High resistance levels to Nalidixic acid (84.8%), TMP ...
