The susceptibility of two collections of coagulase-negative staphylococci (CNS) isolated from clinical specimens for teicoplanin and vancomycin were compared. They comprised 91 and 101 isolates, collected in 1985 and 1994 respectively, from different departments of a teaching hospital. MICs of vancomycin and teicoplanin were determined by a modified Etest method. Additionally, a disc diffusion ...

The present study was conducted to evaluate the performance of cefoxitin disc diffusion method and oxacillin broth microdilution method for detection of methicillin resistant S. aureus (MRSA), taking presence of mecA gene as reference. In addition, inducible clindamycin resistance and beta-lactamase production were studied and minimum inhibitory concentration (MIC) of vancomycin for S. aureus i...

Using the guidelines of the National Committee for Clinical Laboratory Standards (NCCLS), a total of 421 blood culture isolates of Salmonella enterica serovar Typhi obtained during 1991-2001 were tested for susceptibility to ofloxacin (OFX) by the disc diffusion method, and for the determination of minimum inhibitory concentration (MIC) values of OFX by the agar dilution method. Among 421 isola...

The aerial parts of Satureja spicigera were collected at full flowering stage at Gazvin, Iran. The essential oil was isolated by hydrodistillation and analyzed by a combination of capillary GC and GC-MS. Fourteen compounds were identified, of which carvacrol (53.74%) and thymol (36.03%) were the main constituents, representing 99.12% of the total oil. The in vitro antibacterial activity of the ...

Objective: The emergence of infections by Acinetobacter spp causes serious threats and further limits the treatment options. The present study aims to determine prevalence of ESBL and MBL among Acinetobacter species. Materials and methods: Various clinical specimens and isolates were identified using a standard bacteriological protocol. Antimicrobial sensitivity patterns were determined using K...

BACKGROUND & OBJECTIVE Treatment of serious life threatening infections due to multi-drug resistant pathogens presents a difficult challenge due to the limited therapeutic options. Therefore, we studied the in vitro susceptibility of tigecycline, a new glycylcycline with promising broad spectrum of activity against Gram positive and Gram negative bacteria at a tertiary care hospital in north In...

The role of magnetic fields for the formation of planets is reviewed. Protoplanetary disc turbulence driven by the magnetorotational instability has a huge influence on the early stages of planet formation. Small dust grains are transported both vertically and radially in the disc by turbulent diffusion, counteracting sedimentation to the mid-plane and transporting crystalline material from the...

Enteric fever prevails as a major public health problem despite the use of antimicrobials due to the emergence of drug resistance. The present study was undertaken to find out the antimicrobial susceptibility pattern of Salmonella isolates from our region. Antimicrobial susceptibility testing for six drugs chloramphenicol (30μg), amoxicillin (10μg), cotrimoxazole (1.25/23.75μg), nalidixic acid ...
