چکیده

We report the first case of a primary group A streptococcus (GAS) psoas abscess in a 31-year-old woman. The psoas abscess was preceded by an episode of acute pharyngitis. The M-protein gene (emm) and streptolysin S structural gene (sagA) were present in the isolate, with no significant amino acid differences from previously described sequences of M1 GAS isolates. Multilocus sequence typing (MLST) showed that the isolate belonged to MLST sequence type (MLST-ST) 28, the predominant MLST-ST associated with invasive disease caused by M1 isolates.

Characterization of naphthalene-degrading bacteria isolated from the Persian Gulf and the Caspian Sea as potential agents for naphthalene removal from polluted environments

Over fifty bacterial strains were isolated from seawater samples in the presence of naphthalene as a sole source of carbon and energy. Among them, three isolates with higher growth rate and naphthalene degradation ability were selected for further studies. Biochemical and molecular analysis revealed that two Persian Gulf isolates, strain PG-10 and strain PG-48 belonged to the group of hydrocarb...

Production and characterization of biochemical properties of L-Asparaginase by indigenous yeast isolated from soil of Iran

Introduction: The use of L-asparaginase as a chemotherapeutic agent is an effective strategy for the treatment of leukemic lymphoblasts. Since the use of bacterial L-asparaginase causes side effects due to hypersensitivity reactions, search for new enzyme sources is one of the active research areas. In this study, the characterization of produced L-asparaginase by indigenous yeast strains was i...

Isolation and Characterization of Melanin Producing Pseudomonas stutzeri Strain UIS2 in the Presence of l-tyrosine and Survey of Biological Properties of Its Melanin

Background: Melanin is a negative charge hydrophobic complex pigment. Melanin is produced naturally in bacteria to protect them against UV, free radicals and environmental stresses. Pigment production in bacteria has more advantages than other biosources due to its rapid growth, higher efficiency and easier extraction. The aim of this study was the isolation, biochemical and molecular identific...
