In an attempt to find a new class antibacterial agents, a series of biscoumarins (1-4) and dihydropyrans (5-13) were successfully prepared. The molecular structures of four representative compounds, that is, 4, 5, 8 and 12 were confirmed by single crystal X-ray diffraction study. These synthesized compounds were screened for their antibacterial activity in vitro against Staphylococcus aureus (S...

A penicillin-binding protein of molecular weight 76,000 inducible by beta-lactams was detected in methicillin-resistant Staphylococcus haemolyticus and Staphylococcus simulans. DNA from these strains hybridized to the mecA gene from Staphylococcus aureus; however, the chromosomal HindIII fragments containing the mecA genes were 3.4 kilobases in S. haemolyticus and 4.3 kilobases in S. simulans.

Antimicrobial resistance is a global health issue in the developing countries. This study was carried out to evaluate the impact of Mr. Trivedi’s biofield energy treatment on multidrug resistant (MDR) clinical lab isolates (LSs) of Staphylococcus species viz. Staphylococcus haemolyticus (LS 18), Staphylococcus epidermidis (LS 21), and Staphylococcus aureus (LS 30). Each strain was divided into ...

Bacteria known in animal infectious diseases can cause challenges in human diagnostic laboratories. We present pitfalls in the identification and susceptibility testing of Staphylococcus hyicus, a pathogen that typically causes exudative epidermitis in pigs. In this case, the coagulase-positive staphylococcus isolated from a septic patient was misidentified as Staphylococcus aureus.

Herein, we describe the isolation of Staphylococcus pasteuri, Staphylococcus pettenkoferi and Staphylococcus gallinarum and summarize the clinical characteristics of five patients. Cases were identified over a 2-year surveillance period that identified the respective strains using microbiologic and molecular methods. These data suggest that rare coagulase-negative staphylococcal infections may ...

Staphylococcus toxic shock syndrome is a severe illness caused by infection with toxin producing Staphylococcus aureus and is associated with a poor outcome. We report a case of Staphylococcus TSS presenting with cough and expectoration along with multiple pneumatoceles visible on the chest radiograph that progressed to acute respiratory distress syndrome with eventual foci in brain. The patien...
