SODIUM CHLORIDE MEDIA FOR THE SEPARATION OF CERTAIN GRAM-POSITIVE COCCI FROM GRAM-NEGATIVE BACILLI

Post-neurosurgical meningitis; gram negative bacilli vs. gram positive cocci

Background: Post-neurosurgical meningitis is a significant cause of mortality and morbidity. In this study we aimed to compare the differences of clinical, laboratory features and outcomes between the post-neurosurgical meningitis caused by gram-negative bacilli (GNB) and gram-positive cocci (GPC). Methods: Cases of post-neurosurgical meningitis (with positive CSF culture) were included. After...

GRAM NEGATIVE BACILLI IN BURNS

In a period of nine months, 225 strains of Gram-negative bacilli isolated from burns were identified by a variety of tests in two burn centers in Tehran. The most common species were Pseudomonas aeruginosa, Pseudomonas fluorescens, Escherichia coli, Enterobacter agglomerans, Enterobacter cloacae and Klebsiella pneumoniae. Many strains of acinetobacter spp, providencia spp, proteus spp, ser...

Antimicrobial Susceptibility Profiles of Gram- Negative Bacilli and Gram-Positive Cocci Isolated from Cancer Patients in Libya

Title: Antimicrobial Susceptibility Profiles of Gram-Negative Bacilli and Gram-Positive Cocci Isolated from Cancer Patients in Libya. Background: Due to defects in their immunity cancer patients are prone to serious infections with substantial morbidity and mortality. However, there is lack of information on the microbial and antimicrobial susceptibility profiles of microorganisms associated wi...

Gram-positive Cocci: Staphylococci

Gram-positive anaerobic cocci.

Gram-positive anaerobic cocci (GPAC) are a heterogeneous group of organisms defined by their morphological appearance and their inability to grow in the presence of oxygen; most clinical isolates are identified to species in the genus Peptostreptococcus. GPAC are part of the normal flora of all mucocutaneous surfaces and are often isolated from infections such as deep organ abscesses, obstetric...
