BACKGROUND Cefoxitin is a potent inducer of the mecA gene. It is currently as a screening recommended method for presumptive identification of isolates of methicillin resistant Staphylococcus aureus (MRSA). The aim of the study was to compare the sensitivity and specificity of the cefoxitin disc diffusion (30 μg) to oxacillin agar screening from detection of the mecA gene by PCR. METHODS Thre...

Intervertebral disc metabolic transport is essential to the functional spine and provides the cells with the nutrients necessary to tissue maintenance. Disc degenerative changes alter the tissue mechanics, but interactions between mechanical loading and disc transport are still an open issue. A poromechanical finite element model of the human disc was coupled with oxygen and lactate transport m...

The heterogeneous expression of methicillin resistance in Staphylococcus aureus affects the efficiency of tests available to detect it. Not all laboratories have access to accurate molecular tests used for this purpose. This study compares the performances of four phenotypic tests used to detect methicillin resistant S. aureus (MRSA) with the mecA gene polymerase chain reaction. Two hundred thi...

With the discovery of newer antifungal agents, emergence of resistance among Aspergillus, is a major problem. In the present study, 25 different clinical isolates of Aspergillus flavus were screened for their susceptibility against five common antifungal agents by broth dilution and disc diffusion method with the aim to evaluate both the methods for their suitability to adapt in clinical labora...

OBJECTIVE To find out the frequency of low-level quinolone-resistance in Multi-Drug Resistant (MDR) typhoid using nalidixic acid screening disc. STUDY DESIGN Descriptive study. PLACE AND DURATION OF STUDY Armed Forces Institute of Pathology, Rawalpindi, from January 2005 to December 2005. MATERIALS AND METHODS Blood was obtained from suspected cases of typhoid fever and cultured in to Bac...

OBJECTIVES To determine the antibiotic susceptibility patterns of 60 strains of Laribacter hongkongensis isolated from humans and fish to eight antibiotics and compare the results obtained from broth microdilution, Etest and disc diffusion susceptibility testing. PATIENTS AND METHODS The susceptibilities of 60 isolates of L. hongkongensis from humans with gastroenteritis and fish to eight ant...

BACKGROUND AND OBJECTIVES Staphylococcus aureus is one of the main causatives of bovine mastitis. Resistance of some strains to methicillin, can complicate the treatment of its infections. On the other hand, enterotoxin production is also important. Therefore, the aim of our study was to investigate the methicillin resistance and enterotoxin production in S. aureus isolates caused bovine mastit...

OBJECTIVES To investigate the reliability of cefoxitin and oxacillin for the detection of mecC-positive Staphylococcus aureus. METHODS The susceptibility to cefoxitin and oxacillin of 62 mecC-positive S. aureus isolates was investigated using broth microdilution, agar dilution, Etest and disc diffusion on different types of media. The data were interpreted for the utility of cefoxitin and oxa...

This paper details the phenotypic, genotypic, and antibiotic sensitivity patterns of 88 Vibrio cholerae strains from Zimbabwe. Of the 88 strains, 83 were classified as "altered El Tor" and 5 as "hybrid El Tor" strains. All of the strains were susceptible to tetracycline, doxycycline, ciprofloxacin, and azithromycin by disc diffusion, but susceptibility to tetracycline and azithromycin diminishe...

background pyogenic bacteria and especially staphylococcus aurous (s. aurous) are the most common cause of chronic osteomyelitis. not only treatment protocol of chronic osteomyelitis occasionally is amiss but also this malady responds to treatment difficultly. objectives this study investigates antibiotic resistance pattern of s. aurous isolated from iranian patients who suffer from chronic ost...
