We describe a patient who developed daptomycin-resistant, methicillin-resistant Staphylococcus aureus (MRSA) during an episode of presumed septic thrombophlebitis of the portal vein. Although daptomycin is an alternative agent for treatment of drug-resistant gram-positive bacterial infections, development of resistance during prolonged use may occur with MRSA bacteremia from a persistent focus.

abstract biofilm is a complex community of microorganisms residing within a polysaccharide and/or protein matrix. biofilm can be produced by microorganisms such as bacteria and fungi. both gram positive and gram negative bacteria have this ability. resistance of biofilm to antimicrobial agents is becoming a global issue. bacterial biofilms are important in various aspects such as chronic human ...

Apical periodontitis is an infectious disease caused by microorganisms colonizing the root canal system. For an optimal outcome of the endodontic treatment to be achieved, bacterial populations within the root canal should be ideally eliminated or at least significantly reduced to levels that are compatible with periradicular tissue healing. If bacteria persist after chemomechanical preparation...

Serious infections caused by Gram-positive bacteria are currently difficult to treat because many of these pathogens are now resistant to standard antimicrobial agents. As a result of the emergence and spread of multidrug-resistant Gram-positive pathogens, new antimicrobial agents are urgently needed for clinical use. In recent years, there has been an increase in the number of drugs that have ...

Methods We performed a retrospective and compared study, between 01 January 2007 – 31 December 2010, in the Infectious Diseases Hospital of Craiova, on two groups of adults patients (Px): group A 114 PIH and group B 1442 Px non HIV, which had been diagnosed with nontuberculosis bacterial infections (BI) with established etiology. For each group we analyzed the incidence, clinical spectrum, etio...

Bronchoalveolar Lavage (BAL) is a medical technique by which cells and fluids from bronchioles lung alveoli are withdrawn for diagnosis of disease or evaluation treatment. Patients with various pulmonary infections follow the procedure BAL as it has high sensitivity reliability in diagnosis. To examine bacterial etiology among tertiary care patients infections, cross-sectional study was conduct...

BACKGROUND Respiratory tract infection is one of the most common reasons for hospitalization among adults, and recent evidence suggests that many of these illnesses are associated with viruses. Although bacterial infection is known to complicate viral infections, the frequency and impact of mixed viral-bacterial infections has not been well studied. METHODS Adults hospitalized with respirator...

Spontaneous bacterial peritonitis (SBP) in patients with cirrhosis is typically caused by gram-negative bacteria. However, the number of SBP cases due to gram-positive bacteria is steadily increasing. To date, little is known about the predictive factors involved in SBP infections.We performed a retrospective cohort study of patients (>18 years) with SBP due to gram-positive and -negative bacte...
