Última Lemierre syndrome from a neck abscess due to methicillin-resistant Staphylococcus aureus BJID Abhishek,Agarwal; Sandeep,Singla; Tarun,Pandey. Lemierre syndrome is characterized by acute septic thrombophlebitis of the internal jugular vein (IJV) that develops after an oropharyngeal infection, and can be complicated by septic emboli to lungs and other organs. The most frequent causative agent is Fusobacterium necrophorum, an anaerobic bacillus found in normal oropharyngeal flora. Staphylococcus aureus has emerged as a cause of Lemierre syndrome in the last decade. We report a case of a 24-year-old man who developed septic IJV thrombosis and necrotizing pneumonia due to S. aureus from an infected hematoma in the right sternocleidomastoid muscle. Antibiotics are the mainstay of therapy with few cases needing anticoagulation. A good outcome is dependent upon an awareness of the condition, a high...

Borage (Echium amoenum) is a large annual plant of the Boraginaceae family, which grows in most of Europe and in northern Iran. The borage flower is used as a medicinal herb in France and other countries. Iranian borage is used in traditional medicine for infectious diseases, flu and as an anti-febrile. We tested the aqueous extract of borage dried flowers in vitro for its antibacterial activity. The extract showed concentration-dependent antibacterial activity against Staphylococcus aureus 8327. This activity was heat resistant, but the activity of freeze-dried extract gradually diminished during a 90-day period. The traditional use of Iranian borage flowers for infectious diseases and for controlling fever appears to be justified.

Staphylococcus aureus infections are growing problems worldwide with important implications in hospitals. The organism is normally present in the nasal vestibule of about 35% of apparently healthy individuals and its carriage varies between different ethnic and age groups. Staphylococcal nasal carriage among health workers is particularly important to establish new clones and track origin of infections during outbreak situations. To determine the carriage rate and compare the pulsed field gel patterns of the strains, nasal swabs were collected from 185 medical students in a teaching hospital in Lagos, Nigeria. Isolates of S. aureus were tested for heamolysin production, methicillin sensitivity and Pulsed Field Gel Electrophoresis (PFGE) was performed. The...

Venom. Anim. Toxins incl. Trop. Dis. Batalha,J. E. N.; Caramori,J. C. T.; Corrente,J. E.; Montelli,A. C.; Barretti,P.; Cunha,M. L. R. S.. The presence of Staphylococcus aureus in the nasal cavities and pericatheter skin of peritoneal dialysis patients put them at high risk of developing peritonitis. However, it is not clear whether the presence of coagulase-negative staphylococci (CNS) in the nasal passages and skin of patients is related to subsequent occurrence of peritoneal infection. The aim of the present study was to verify the relationship between endogenous sources of S. aureus and CNS and occurrence of peritonitis in patients undergoing peritoneal dialysis. Thirty-two patients on peritoneal hemodialysis were observed for 18 months. Staphylococcus species present in their nasal passage, pericatheter skin and peritoneal effluent were identified and compared based on drug...

Galbanic acid, a sesquiterpene coumarin from Ferula szowitsiana roots, was investigated for its potentiating effect on the antimicrobial activity of antibiotics as well as ethidium bromide, in 6 multidrug resistance (MDR) clinical isolates of Staphylococcus aureus. Galbanic acid had inhibitory effect on none of the isolated bacteria tested (up to 800 µg /ml). The MIC range of ciprofloxacin, tetracycline and ethidium bromide, against all tested S. aureus were 10-80, 10-80 and 4-16 µg/ml, respectively. These were reduced to ≤2.5-5, 2.5-5 and 0.5-2 µg/ml in the presence of galbanic acid (300 µg /ml) or verapamil (100 µg /ml). The rate of ethidium bromide (2 µg /ml) accumulation in clinical isolates was enhanced with galbanic acid (300 µg /ml). There is also a...

O.; Côrtes,M. F.; Bandeira,P. T.; Figueiredo,A. M. S.. Biofilm formed by Staphylococcus aureus is considered an important virulence trait in the pathogenesis of infections associated with implantable medical devices. Gene expression analyses are important strategies for determining the mechanisms involved in production and regulation of biofilm. Obtaining intact RNA preparations is the first and most critical step for these studies. In this article, we describe an optimized protocol for obtaining total RNA from sessile cells of S. aureus using the RNeasy Mini Kit. This method essentially consists of a few steps, as follows: 1) addition of acetone-ethanol to sessile cells, 2) lysis with lysostaphin at 37°C/10 min, 3) vigorous mixing, 4) three cycles of freezing and thawing, and 5) purification of the lysate in...
